A young man who has lived on earth for 25 years and loves machinery and mechanisms.
Accidentally traveled to a world similar to Earth.
After being adopted by a crazy old man and teaching him the "Atlas of Heavenly Craftsmanship" for half a year, the crazy old man suddenly said that he had something to do and left for a while, and he has not come back since then.
Suddenly after the boy turned 18, the two of them found Mubai and embarked on the adventure of searching for people. Then they discovered that the world was completely different from the world he imagined, and that the secrets of the ancient gods actually existed in this world.
(Ps This book will stop updating for a while. I will open a new book. If you want to read it, you can pay attention.)
