I really love isekai/reincarnation stories that focuses on helping/improving people lives, health, or economy. If you know any manga like this, and that has a good overall plot and characters, please recommend me some! Thanks!

the only one i can think of is this:
http://www.mangago.zone/read-manga/daites_ryou_koubouki/hs/hs_chapter-1/

http://www.mangago.zone/read-manga/cheat_pharmacist_s_slow_life_making_a_drugstore_in_another_world/
is another one like this one where the MC is involved in pharmaceuticals. though it's on a smaller scale and more relaxed slice of life.
http://www.mangago.zone/read-manga/shin_no_nakama_janai_to_yuusha_no_party_wo_oidasareta_node_henkyou_de_slow_life_suru_koto_ni_shimashita/
he runs a little medical shop. slice of life.
http://www.mangago.zone/read-manga/tensei_shite_inaka_de_slowlife_wo_okuritai/
he invents stuff and helps out his father's domain. slice of life.
http://www.mangago.zone/read-manga/isekai_kenkokuki/
a lot of land development and inventions to advance the economy. has action but is also kinda slice of life.
http://www.mangago.zone/read-manga/isekai_nonbiri_nouka/
title kinda says it all. farming life in another world. slice of life.
http://www.mangago.zone/read-manga/jui_san_no_oshigoto_in_isekai/
he gets summoned to this world to cure magic diseases, turns out the diseases weren't all that magical but he cures them anyway.
http://www.mangago.zone/read-manga/genjitsushugisha_no_oukokukaizouki/
i dunno that i'd say he helps out the economy, but he does end up having to run a kingdom and deal with a war.
http://www.mangago.zone/read-manga/kenja_no_mago/
this one is kinda pushing it, but he does make a lot of magical inventions that boost the economy i guess?

This has action and harem, but the invention parts and development of characters are good... Ive read the novel

I am also in love with those kind of stories! If you are still looking for something to read, I recommend these 5 to you:
Doctor Elise is very similar but with a female lead. [Reincarnated, Medical, Webtoon, Europe-like setting, Awesoomee! haha] :
http://www.mangago.zone/read-manga/doctor_elise
If you liked it, also try Medical Return which is another work of the same author [Reincarnated, Medical, Modern setting, Webtoon, Male lead] :
http://www.mangago.zone/read-manga/medical_return
Another is That Time I Got Reincarnated as a Slime (If you haven't tried it yet...) [Reincarnated, Kingdom-building, Male lead?, Manga/Anime] :
http://www.mangago.zone/read-manga/tensei_shitara_slime_datta_ken
Also try The Accomplishments of the Duke's Daughter.
[Reincarnated, Manga, Economy stuff, Female lead] :
http://www.mangago.zone/read-manga/koushaku_reijou_no_tashinami
And lastly, try The Beginning After the End. It's only in the reincarnation tag, but it is lit! [Reincarnated, Magic, Webtoon, Male lead, Awesoomee!] :
http://www.mangago.zone/read-manga/the_beginning_after_the_end/?av=1
I think you should try Doctor Elise first, since it is the closest, I think, to what you're looking for. And it's very timely cuz it also have parts about a plague. (๑•ㅂ•)و✧

YEAHHH IKR!!! I think it was kinda more serious, yet still fun, in the novel. RTW was the novel that I enjoyably tried to finish. I tried to check the webtoon and I dropped it at the first chapter. I felt really disappointed. It was better in the novel for me. They should've just continued the anime adaptation or left it as is.( ̄へ ̄)

I really like that the plot is focused mostly on the main leads (so far) and without any unnecessary second love interest or evil villain/villainess. Would anyone recommend me a webtoon/manhwa similar to this? Thanks! :)

And a second love interest is good to add some 'spice' to the story ya know what I'm saying? But hey, you do you! If you want up to 5 love interests GO OFF LMAO but if you just want one ML and one FL then hell to the yeah with that too! As long as you enjoy writing and drawing the story it's all good!

Awwwwww
Thanks a hecking lot. That was very encouraging and helpful.
I'm currently worrying over killing my future readers because oh how dark the story is, it contains lots of tragedies, half tragedies, well half tragedies? (Time keeps rewinding itself so~). There will, however, be a love rival and a half (the half is the male lead himself having another identity no one even himself knows he had. Don't ask how XD) I shall strive to make a love rival strong enough you actually wouldn't know who she'll end up with kekeke!!
Right now I shall focus on characters development not only for the main characters but the side ones too, though I am afraid it might cause the story to be extra complicated as it is complicated enough now and also some comedy.
The most interesting part is that I came up with this very complicated story while being bored in an Arabic (native language) grammar class 3 years ago.

And actually
My profile picture is a fast sketch I did at school today
Noro. An 11 year old boy with a cold personality, he had his own shares of tragedies. He is very smart and insightful. He also has very rare powers within him many clans fight upon which is the reason he has this pale skin, white like snow hair and ashy light blue eyes appearance, he is one of the "white children" a very complicated topic I came up with and he's an even rarer type of them.
Just thought I'd sketch him smiling lol.
Spoiler:
Poor him. I might actually kill him in one of the endingS.

Their not bad at all! I also love reading them, and I think the majority of people do too! I just posted my original question because I have been obsessed (lol) with reading webtoons that always contain a love rival or villain/villainess that I thought this was a nice change.
To be more specific about what I liked about this story, maybe because it doesn’t have any big drama and this makes me focus more on the leads and their growth for each other? ٩(๑❛ᴗ❛๑)۶
By the way, your idea for your story sounds amazing!!! I do love complicated stories that makes we want to know what happens next :)

Interesting opinion, I shall work on that! I shall give one of my characters something like that. Although my story does not in fact have an actual villain which is hard to make a story like that. I believe the only villain would be themselves.
Hmmm letting the reader focus on the growth between them rather than the drama. Refreshing indeed. It should be alright with her mother's old friend a baker who quit being a herb doctor after failing to save someone precious to her, she took care of Medori the female lead after she lost her parents in a fire accident when she was young. It should work between that woman and the red moon clan commander as he turns out to be that person in the past she thought she lost.
Since I haven't decided on an exact storyline for it yet. During the story I'll let the two focus more on the obstacles and walls between them, let's say I was inspired by The Vampire And The Maid for this one hehe (▰˘◡˘▰).

I don’t mind a second love interest, but I personally hate it when the main girl/boy is obviously in love with one of the love interests and still gives hope to the other one. (Spoiler if you haven’t read or watched the Twilight series)
For example, I read the Twilight series and I couldn’t have hated Bella more than when she was pining over Edward, but still tried to date Jacob!!! God, I really hate when someone knows the other person loves them and they know they don’t love them the same, but they still try being with that person for what ever reason. It gives the other person hope only to hurt them in the end!
Sorry if that got confusing and long. I would love to check out your story! What’s it called?

Oh my Gosh YES!!
I HATE IT TOO
Like what even is the point of the love rival itself
That's why my heroine haven't really figured out her feelings for any of them at all first.
I call it Scars Of Truth(-the black moon).
But nothing is released now. As I am still an 11th grader who must polish their drawing skills (honestly I suck at drawing) and work on the story before even start drawing the actual thing, I don't have much experience when it comes to this, there's also the fact that soon I'll become a 12th grader which is called Tawjihi in my country.. the most nerve-wracking one of them all *sigh*. And the fact that my parents who refuse to buy me a pencil so I don't draw and this country doesn't give much support tho these stuff. I must say I am kinda nervous about the story, I want it to be perfect, I just want people to enjoy it and remember it, I'm a perfectionist when it comes to my creation AND I'm also a lazy person XD There's also the fact that I should improve my drawing style. As people

Ah did I mention one of my characters is actually my friend and classmate who let's pretend she reads my manga reincarnated after her death (I had lots of fun asking her creepy questions like how she wants to die when she had no idea at the time)
So I included her in my story as a way of mourning for her. And like that, she got reborn into my world lol. I even gave her my friend 's nickname.

http://www.mangago.zone/read-manga/jishou_akuyaku_reijou_na_konyakusha_no_kansatsu_kiroku/
its been awhile since ive read some of them but they might be similar to what you're looking for : ) either way, I would suggest them anyway bc I enjoy them a lot

Its bad, a second lead character just spells lazy writing.
Why put a character in a story, if their soul purpose is to blindly fall in love with main lead character but never stand a chance?
They have no substance and growth, or they so lovable and caring but always loose to the douche male lead. They existence shouldn't be to distract and create drama.
The story should be creative, new, unique and stand on its own. It shouldn't have to rely on a worthless character to keep readers guessing or interested.
Dare to be different second leads are cliche and a thing of the past. The maid and the vampire is proof of that.

That's because the story doesn't really revolve all around the love between the male lead and the female lead, or romance. I left the shipping to my possible future readers(even though I already have my favourite shipping lol).
But I as a reader and not an author am sick of all those nice guys being thrown away in manga as supporting characters. That's why I'm only making multiple endings

Ah I posted accidentally before finishing lol;
That's why I'm only making multiple endings, so that no one lose.
Now that I think about the reasons why there are multiple endings can be linked to the actual plot of the story (an idea just popped in my mind) wooooha this is genius XD don't wanna spoil lol.
Why make 2 stories with the whole purpose of having a character ending up with a different guy in each, when first that isn't really the whole thing to the story and second, it's just inconvenient and unnecessary. Making multiple endings sounds better.
How about (I'm literally organizing my thoughts here lol) towards the near end of the story, the story shall branch into two timelines. In each the story will start developing for a different target, just like routes? The other 2 endings I planned from way before, don't exactly focus on the shipping, but the way the story unfolds. And I plan to put a bitter sweet ending in one and a FREAKING plot twist in the other lol.

But right now I'm working so hard on the balance in the story.
So I don't have a big villain in the story, which I think is good as I'm not going for a typical revenge story, as I want to make the story as original as possible, and revenge stories are boring these days.
The balance I'm talking about is the balance between light and darkness in the story, or like joy and sadness. Since my story is just filled with lots of negativity, I'm seeking to add joy and organize it in the plot, but it's hard.
Also I'll have to be careful about the character development!
Woha this is an important point as a reader.
Characters need to have depth which is already not so bad in the story. But development in the characters as plot unfolds is necessary.
AND there's the fact that I'm working on making the plot follow the other characters than the main ones as well. And develop every one of them. Ah this is so hard.
I'm also worried about my female character having a weird character. Of course she isn't the weak stupid type but isn't arrogant jerk one too. Since she suffers from depression and suicidal thoughts, is smart and not gullible, kind and caring, and also a herbalist doctor. I really wonder if she is weak for suffering from depression and self hatred or if she is strong for having firm principles, courage and responsibility. Like this mix of personality is just so unusual and is risky for me.

Okay..why herbalist though?
You have to sell the character make her believable and relatable, then readers will take to her easier.
Suicidal thought and depression aren't weak...it really depends how you portray her...if she is always talking and feeling sorry for herself then weak...but if she acknowledges her short comings and doesn't let them hinder her and tries to deal with said issues then strong.
I really like that your taking you time to iron out the wrinkles in story, a good writer always brain storms extensively.

Thank you, I mean I really want to make the story perfect if that's even possible, I want my story to have impact, depth, meaning and entertainment that and also well balanced. I do not want it to be one of those boring, not well-thought-out, typical mangas that just waste my time. That's why I've been slowly working on the story in my head for 2 years now and still not even close to finishing, I want every detail to have a story or reason behind it, even though I'm worried it'd be over detailed.
About Medori (you may as well call her female lead) being a herbalist, imma just jab down some backstories here so brace yourself XD I'm sorry lol
that's because people in the small villages had to depend on herbal medicine to treat the sick, as it was the only thing they could depend on. Actually it's more of Traditional Chinese Medicine to be honest, but they call it Traditional Herbal Treatment Science, and Medori would be called a herbalist treater. So back before the War of The Cursers reached the country, when Medori lost her parents (to which I'm developing their backstory and connecting it with the story) in a fire accident in the tree house that belonged to her parents, to which Medori caused the fire by accident, I was so sad drawing sketches of this part, drawing the whole accident, especially since the male lead from the present would also be watching the incident next to a small traumatised Medori as he was involved in time conflicts at the time.
So basically after she lost her parents she then had to live with one of her mother's old friends, a woman who is a baker and a boarder in her house, to which the woman (who actually has a story of hers and conflicts with Medori's mother and a knight from the red Moon clan) who now is a baker, used to be a successful herbal treater but quit the career after losing her lover in the past leaving it behind her forever. Medori after meeting Akai (oh boy Akai has a huge plot twist there! XD, he's Sagatsuka the male lead's other identity but no one knows about that, not even Sagatsuka or Akai themselves know about that, and so they are now treated as two different people to other people, it's hard to explain it lol) so anyways after Akai and Medori met when they were kids but a little older than before and Medori realized she wanted to become a stronger person, her mother's friend started teaching her Herbal treatment. Thus that's why she became a herbalist XD there you have it!

Cool, I'll be on the look out for when you release it! I think it's a good idea to focus on the story first and slowly build up you drawing, especially because you're still a student! I love trying different types of art, but I'm not that confidant in my drawing skills, lol! It's so awesome that you have something you love and want to work towards! I wish you all the best!! ٩(๑❛ᴗ❛๑)۶

Thank you so much!! I appreciate it. I too feel like my drawing skills aren't ready yet to publish officially. I'm really not confident at all with any of my skills including singing and writing.
Your drawing skills can be developed by practicing, learning how to practice efficiently (YT can help you with that), using your imagination to be flexible like having a deep understanding of what you're drawing (for example you are drawing a head you saw on pinterest, imagine the skull and the angle and understand what you are drawing, that way you'll remember it better next time), observing everything in drawings you see and wonder how it was drawn, what type of brushes or tools used, colours, shading and lights effects, layers?.. etc just analyse and observe even if you don't really draw what you see (reading manga and manhua really helped me with that a ton as I don't really practice by coping a lot which is not good). The most important thing about that is your passion to drawing, sometimes you'll feel like not drawing at all heck I'm always like that, I'm lazy, but at the end of the day, I still love drawing and know I'd still go back to it after a while.
I mean I started drawing at 3rd grade after my home room teacher was in shock after she saw my drawing and called the whole teachers in the floor then filmed me explaining my drawing. I was dumbfounded but after that motivation I never stopped drawing. I self-taught myself drawing.
Wth Lucas! I wanted you to have a redemption-arc to turn you into a less-of-a-jerk friend/ally... BUT not anymore! I hope he gets the punishment he deserves and not just forgiven like many shonen mangas! (/TДT)/
From what I heard, Lucas isnt getting a redemption arc ( ̄へ ̄)
Good. That bitch dont deserve a redemption
GOOD! he doesn’t deserve it ╮( ̄▽ ̄)╭
Agreed! ٩(๑❛ᴗ❛๑)۶
