Civilized Survival: I Build Infrastructure in the Wilderness

[Invincible flow + wilderness survival + infrastructure + pollution alienation + immortality] The end of the world is coming, when everyone is trying their best to become stronger, form a team, and struggle to survive. Cheng Yan, a retired mercenary, awakened the top rule-level plug-in [Immortal] at the beginning, and began to live a peaceful life in the apocalypse—— He fishes while others are leveling up, and sleeps while others build houses. Others only want to reach the top in their lives, but when he wakes up, he finds that there is no one else on the top of the mountain. Many years later—— The greatest head of state of the new era wrote on the title page of his memoirs: "He is the most important guide in my life." The man who is known as "the strongest human being" and who once killed an alien master by himself only said one sentence in the interview: "In front of him, I'm just a new recruit." As for those top experts who have fought against Cheng Yan, or who were lucky enough to receive his "guidance"—— A: "You can't defeat it even if you try your best." B: "Sir Cheng Yan's casual remark, I want to stay at home and spend my life trying to understand it." C: "Master Cheng Yan is very close to God..." D: "I am Lord Cheng Yan's dog!" E: "I'm really sorry that I couldn't make Mr. Cheng Yan happy..." … Until the ultimate BOSS that almost destroyed human civilization, seeing the man who could not be killed no matter how hard he tried came through the air again with a hundredfold increase in strength, his pupils were shaken, and he was finally completely broken: "Damn it, this one is Gui!" Cheng Yan wiped the blood and said calmly: "It's not off, it's just not on."
