I Signed up with the Gods in God's Forbidden Zone

In 2012, indestructible black towers appeared one after another around the world. The outsiders used the black tower as a beacon and turned the earth into a battlefield. Known as God's Forbidden Zone. Fifteen years later, human civilization has its own way. Fight back against these restless visitors in a post-apocalyptic world. It was in such an era that the time traveler Zuo Zhe gained the ability to sign contracts with the gods. Standing on the wave of the times little by little... "I am a descendant of the gods, the heavens above the human world." Zuo Zhe said. "The world is a beast that feeds on mediocrity," said Chitu, the outsider. When the gods became the support behind Zuo Zhe. It turns out that the earth has been an arena since ancient times. Constant destruction and rebirth, when the gods no longer tolerate it. He could finally say that to outsiders on behalf of mankind: "Visitors, you are the challengers."
