Douluo: on the Wedding Night, Xiao Wu's Mentality Collapsed

Tong Hu traveled through the fairyland and bound the system.
At the beginning, marry the human daughter Mei Gongzi of the Peacock Demon King, conquer the world, fight the demon clan, destroy the demon emperor, and redeem the human race to become the masters of the continent.
"It was detected that Young Master Mei's mentality had collapsed, and he was deeply attracted by the host. Do you sign in?"
"Sign in successfully, reward 3 stand-in dolls, and awaken the infinite swallowing skills!"
"It is detected that Mr. Mei has lost his life direction and needs your guidance urgently. Do you sign in?"
"Sign in successfully, the system will reward you with a splendid upgrade package, and open up a chaotic battlefield!"
......
In this way, before he knew it, Young Master Mei finally found out that his previous life was actually Xiao Wu from Douluo Continent.
And her husband's name is Tong Hu.
