The Age of Monsters in the City

Ye Xiao was reborn in an era where monsters reigned supreme, and was given a system that he thought would make him awesome. But the result is of no use. It also requires double cultivation with a monster or immortal cultivator to open it. What kind of bloody system is this? What? With the Yin and Yang Eyes, it is the core of the dragon vein, and can only suppress monsters in certain areas. He is also a rare five-element spiritual root that can only be seen in ten thousand years. His future is limitless. The spiritual energy of heaven and earth gathers into one body, and he must never die. Immediately, the fox demon Su Jiu'er, the Taoist Guo Shuang, Li Muzi who failed in cultivating immortals and overcoming the tribulation, and Ru Yue, who relied on her charming skills, all came to serve. Everyone wanted to practice double cultivation with him, and Ye Xiao instantly found that his cock was hard... Now, is it okay to activate the system?
