Abyssal Sovereign: The Demon's Dominion - Chapter 6: THE NEW SYSTEM AND WTF..

After being imprisoned in the basement by her mother for ten years, she ended her cruel and tragic life in death when they forced her to hand over the key to the hidden treasure. Getting reborn in her teenage years, she woke up in the bed of that terrible and powerful man. This time, she must take revenge on her enemy, and now she must live.

When we lose our hearts to the wrong person, setting a betrayal in place, how well do we come out from such hurt?

Tang Hao was an honest man making an honest living, but despite all his honesty and kindness, life often looked the other way. Even when he stood up for a man in the streets, he ended up being beaten to a pulp and the man he stood up for? He disappeared. That left Tang Hao with nothing to prove and a hefty medical bill blowing through his savings. However, while he lay unconscious in the hospital, he could feel a warmth coming from the jade pendent he wore as it began to feed him with a trove of priceless information. Now discharged, and still armed with the same naivety and honesty, what will our village peasant do with this newfound power? Will he go on to conquer the hearts of a hundred women? Will he defeat the mightiest crime lords? Only time will tell, but for now, fate has many whimsical plans for Tang Hao.

I finally managed to kill the demon lord.
