Try Return of the Flowery Mountain Sect. Both mc's are super similar; they were both hellishly strong in their past lives, reincarnated with past memories, and are now trying to restore the powers of a sect. They both also love money and the like, are training the other disciples, and put on a face in front of the masters but resort to violence otherwise lol. There are also no females as of rn, and I am enjoying it quite a bit, so I highly recommend!

^Yes I can't believe I didn't mention that. Lightning Degree is absolutely hilarious. It isn't an isekai, but has many similar elements to Path of the Shaman. After mc's parents pass, while mc is sculpting, he catches the eye of this old man who invites mc to be his disciple. Under the supposed farce of teaching him martial arts, the old man makes the mc do household chores and 'sells him' to various professions to earn money.
As expected, the mc grows up to be very similar to his master; he ends up loving money and is super lazy (like mc in Path of the Shaman). Mc is also a genius, (so while he wasn't isekai-ed with past knowledge), he is heaps of times stronger than people who are even triple his age.
Later on, due to some circumstances, mc disguises as an old man, and begins teaching other disciples (without his master's knowledge) (ike Path of the Shaman as well). He teaches these disciples using the same absurd techniques his master taught him, and they all end up becoming super op.
Where it is currently at, the mc is attending a martial arts school (same one where he was disguised as a teacher earlier).
Overall, characters are all fun (and no romance/female lead), the plot is good, and it was a super interesting and fun read, so I definitely second this recommendation
Anyone know similar manga as this one?? Like funny, action/Martial Arts and no female whatsoever just with a twist of isekai, like they are op but have to start at level 1 again but with past memories and leaning more into action stuff and being funny at the same time(づ ̄ ³ ̄)づ
