The Eternal Demon Lord

The martial arts school is a complete scumbag; they even cut back on any new recruits. I just can't understand how they managed to become so big.

The protagonist doesn't have any illness, so why is he so out of breath after climbing only three floors? Why is that so absurd? Did anyone notice that this was mentioned earlier?

It's a pity that so many of my favorite works have been taken down; I've forgotten the details of them over time.

Having read up to Chapter 98, I noticed several plot holes. First, the protagonist was clearly feigning injury to set a trap for the powerful families, then immediately went to fight in underground boxing matches, even using his real name. Are you sure the powerful families aren't blind?

Is this the author who wrote "The Old Ruler"? The author's name looks familiar; "The Old Ruler" is still in my bookshelf, but it shows as unavailable and I can't open it, nor can I see the author's page. I hope the new work is good.

The writing was good before it went on sale, but it really got awful in chapter 92. The protagonist feigns injury to hide his strength in front of his backers and rival families, hoping to gain benefits and secretly improve his power. Then he goes to fight in an underground arena, not hiding his identity and even using his real name.

The plot is moving too slowly, and the sudden decision to participate in an underground boxing match is baffling.

The plot and ecosystem of conflict within this martial arts school are too distorted; the way the plot is advanced is too forced.

Is it similar to the Nightmare Summoning skill?

How is strength determined? Sometimes the protagonist seems really powerful, but other times they still seem like a nobody.
