I'm Already Invincible, and You Just Traveled Through Time?

My name is Shen Yuning, a student at Jiangcheng University. A 'civilization trial' game triggered by cosmic turmoil has swept countless civilizations, including the earth. Nearly half of the people in the world will travel to the cruel worlds. Unfortunately, I became the first in Daxia, and it was still a terrifying and strange world. Fortunately, I was able to contact the country! For the sake of my compatriots in Daxia and the future, the country is ready to mobilize the whole country to let me become a master of tricks first. But in front of the ten strange kings who revived one after another, it was impossible to survive. I had no choice but to look for the legendary weird emperor who once ended the weird era. However, when I went through all kinds of hardships and finally got down in the worship procession of Wangui and was about to call out to the Emperor, I actually saw my childhood sweetheart! Daxia was confused: "What do you mean the full-level Gui Emperor is a member of our family???" … After Ning Wuque returned from the heavens, he became an ordinary college student again. I thought I would live a normal life, but I didn't expect that the mysterious world that he had once destroyed would suddenly receive a summons. ——It seems that this time, I really have to take action.
