Bai Xiao arrived and raised his head. Not only did he see this bizarre and magnificent world, he also saw the career modifier he had downloaded before traveling.

The world's largest urban agglomeration, a rainy night.

The God of Martial Arts has descended on the final battlefield!

Metal mechas with terrifying energy, biological armors extracted from monster cells, and the cruel battle between old and new technologies has begun.
In this era alienated by machines and foreign objects, shouting about the power that belongs to humans may be unimaginably romantic...
