Kaiju Yi Zuo Shan

Starting with a mountain fort with just his general and his squire, he will build it into a mighty fortress. A man was transmigrated into a war-torn world, in charge of a gang that was about to break up. In this kill-or-be-killed era, will he be a mountain bandit, content with robbing money, food, and girls to live an easy life. Or will he be more ambitious, set out to take on the world's heroes, and build a legendary legacy. It's time to ask the question: Men, do you have the courage?
