The End of the World: Awakening of the Backing System, the Strongest Contract

[The end of the world + rebirth + cool writing + decisive killing + not the Holy Mother] Wang Xi was reborn one month before the end of the world and awakened the backing system. The stronger the backing, the stronger I will be. Wang Xi decided on the spot to inform the whole country about the matter, and mobilize the whole country to find the strongest person in his previous life, and then establish a contract with him. The gods who forced humans into captivity underground in previous lives could only be solved by Wang Xi's support. ------ When Wang Xi stood in front of the gods, the gods laughed because of Wang Xi's fearlessness. When a backer appeared behind Wang Xi, the gods stopped smiling. When three backers appeared behind Wang Xi, the expressions of the gods gradually became distorted. When seven backing mountains appeared behind Wang Xi, the gods fled away.
