MTL - Monster Hunt: Notes From a Hunter - Chapter 766 long wait

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.

Xiao Chen, “the waste” of Xiao clan, had his engagement to the Young Lady of the Yang clan renounced.

And when he arrived at the sect that sympathized with him and took him in, he found corpses strewn all over the place and a mist of blood in the air. The sect was exterminated by a mysterious group that was looking for the ‘Wind Spirit Jade’.

He himself was left behind only half-dead for ‘wastes do not deserve to die by their hand’. Humiliated once more and on the verge of death, in the surroundings strangeness happened. A whirlpool sucked up the blood mist and diverted it into Xiao Chen’s forehead, transforming and enhancing his body.
