MTL - Reincarnated Devil King - Chapter 108 I can't beat my kids

A teen is summoned to another world as the Hero. It turns out the Hero can power up women with his cum.

The novel follows the story of Arnold, a porter, who accompanies warriors and superhumans inside dangerous dungeons, which are distinguished by their colours. The porters were always mistreated by the modern human civilization and even though their job was riskier than that of warriors and superhumans, their existence was never appreciated nor were they paid well. No one knows why these dungeons started to appear all over the world. The only thing they know was the dangers that would find their way into the world if they didn’t kill the monsters. But only a selected few cared about the calamity because for the rest it was all about earning money and gaining power. But nothing in this new world is constant and everything keeps changing, and this time the change would find its way towards an ordinary Porter. After stealing a scroll from the dungeon, he ran off to his home. The scroll gave him powers no one could’ve imagined to gain. But he wasn’t alone. 9 other humans had been granted similar powers... powers of the Gods! What would Arnold do with his newfound powers? Will he kill the other 8 Paladins and rule over the world which had oppressed him for years? Or will he rise against the Gods and make them repent for their crimes? Can the strength lent by the Gods be sufficient to deal with them once and for all? Would he be able to defeat his creator? Or will he join the Gods instead? Too many questions, too little time.

- Description from novelbuddy

In novels with a stud there is always a Senior Martial Brother like this:

In the early stages of the novel, his innate talent is high, his cultivation is good, his appearance is handsome, and he has an intelligent, cute younger Martial Sister as a fiancée.

In the middle stages of the novel, he is caught unprepared and defeated by a young disciple (the protagonist) in the sect who’s hardly remarkable at all. From then on, he falls from his godly altar and loses his brilliance. Even his young Martial Sister leaves him for someone else.

In the late stages of the novel, he continues to turn dark, going down the Demonic Path and becoming the major villainous boss. However, the protagonist still ruthlessly defeats him and his soul is eternally sealed.

Once Qin Mo opened his eyes, he discovered that he had become this Senior Martial Brother.
