Legend Of Monsters

*What is a human? 
What is a demon?
What is the purpose of living?
What is the true face of the world?
From ancient times until now, countless lives had struggled between life and death. 
Why was this all happening?
All these questions constituted the entirety of Shenglian Mountain, a person who appeared out of thin air, had no past, and did not know where his future might lead.
Thus, in order to find out the answers to all the questions and their meanings, when he was sixteen, he carried a sword on his back, and from then on, he traveled a long and long journey in search of the truth.
