What's Wrong with Me Being Crazy?

In the next century 300, an unknown zombie virus sweeps the world. Since humans cannot compete with zombies, some people have developed their own powers due to the environment. Nian Yanxi, Gu Yan's old enemy in his previous life, is a person with both fire and water attributes. The "savior" of the end of the world is not the Holy Mother, and it is not known that she might be in a bad mood sometimes. He has the strength and decisiveness of a leader, but in private he is very unruly and a troublemaker... He is the new order of this apocalypse, and he wants to end this chaotic apocalypse. But there was one person who was just the opposite. That is Gu Yan. Gu Yan's thoughts were distorted because he experienced inhuman experiments before the end of the world. He carries a powerful zombie virus in his body, but the drug cannot assimilate it. Looking at the mess outside, he thought that the world would sink and be destroyed with him. As for how the two of them became enemies... A chance encounter. When Gu Yan was giving a speech at Nian Yanxi's base, he "accidentally" barged in and started to contradict him. He said one thing that Gu Yan said was worth ten, so Nian Yanxi couldn't bear it anymore and kicked him out of the base. (You're so irritable, be careful of chasing your wife in the crematorium in the future) At this point, the two of them formed a rift. After that, the two started fighting each other as soon as they met, and they didn't like each other. Yesterday you came to my base to provoke and cause trouble, and tomorrow I will save the people you want to kill... No matter how angry you are, I like the way you dislike me and can't kill me... When they were collecting supplies in the laboratory, the two met again. After several arguments, the two got into a fierce fight and actually detonated the chemicals in the laboratory (two unlucky guys)! This move brought him back to before liberation, and Nian Yanxi traveled directly back to 10 years ago. And the first thing he did when he came back was to go to the laboratory and fish out Gu Yan. Gritting her teeth, she became his "guardian" and wanted to straighten him out. Of course, our Yanyan was not easy to mess with before, and we almost pissed him off at first. So during these 10 years, they began to have a love-hate relationship. Finally, Nian Zong won and finally corrected him. (It's really not easy, hee hee) And the two of them became friends unknowingly. (/Partner) Of course there is still mutual loss, but it is not so tit-for-tat. This was really a beating from the floor to the bed~ "Gu Yan! You have turned this world into a mess!" "Haha, then drink it, my Holy Father!" Intention: I want to write a novel
