Historical Fiction Characters Saving the Earth System

"I am Wu Dalang. My talents are singing and playing musical instruments. My main business is selling cooking cakes. Welcome everyone to my live broadcast room," the system summoned character Wu Dalang said. The earth where Su Chenyu was lying on the bed and playing a certain tune was attacked by a meteorite that suddenly appeared around other planets, destroying everything in an instant. Su Chenyu traveled to half a year before the destruction of the earth, and obtained a system that can summon characters from any novel. By making money, he can buy awesome characters, make money through recycling, and unlock the ultimate password, thereby saving the earth. The first character Wu Dalang summoned, and the second awesome character Qin Shihuang summoned, but neither of them was the final figure to save the earth.
