The chapters are all messed up

Yes, I was really confused.
I think he first visited the mirror world accidentally,
trained under the sword devil leader and before he died received his power.
After the leader died he went back. He was there for a year.
When he was back, he had to study for exams so he went into the mirror to learn.
The old man found him before he could even start.
They moved to headquarters and were attacked.
He was protected and fled, lots of people died for him.
He went back through the mirror, trained and rescued the girl and the dude.
He went back through the mirror again and after he settled the trouble in his world and got the bad guy jailed he walked through the mirror again, but couldn´t go back.
Really confusing were the chapters where he wears the white clothes and is already the leader and the old man that I thought was already dead because he protected him served him and taught him......
I hope the chapters get fixed

I read the first chapter on Lezhin and felt intrigued, so I went ahead and bought the next four episodes. I didn't like them at all and felt like I gave my money to something stupid. But since I had already put money into it, I decided I could just as well read it to the end and bought the new chapter each week and honestly I feel like now it has become interesting again! It's not as cliche anymore as I feared it would be.
