Survival in a different apocalypse, behind-the-scenes mafia flow, technology farming.
On the first day of the apocalypse, seven billion people around the world collectively traveled through the wasteland. Electronic equipment is scrapped, civilization collapses, acid rain corrodes flesh and blood, and alien beasts roam the wilderness.
Lin Mo huddled in the ruins and was bound to the [Civilized Mentor System], and from then on he became the "anonymous father" of all mankind - when others drank sewage and chewed tree bark, he casually threw out the water purifier blueprints; when the camp was besieged by rotting wolves, he taught ultrasonic weapons with his backhand.
When the survivors knelt down and begged for "the true face of their mentor," they didn't know that he was on a mission wearing a vest: intercepting alien signals with hand-rubbed radar, deciphering the runes of ancient civilizations, and unlocking energy technology... Until one day, a thousand-meter-long giant ship descended from the clouds of acid rain, and everyone discovered——

And the mentor who taught them to tear apart the apocalypse had already twisted the Blue Star technology tree into a star destroyer cannon, and was anonymously issuing the last instruction: "All humans, reverse invasion today!"
The subject matter is novel and worth a look
