Transmigrated Into a Zombie, I Grind Tech at the Library

[Zombies + apocalypse + technology flow + no system + library + Gou system] On the day he traveled through time and became a zombie, Dalin just wanted to go back to the library and finish reading the unfinished books. There are seven million copies, so it's good to read them one by one. It's a pity that the end of the world doesn't leave time for zombies to study. There was a power outage, the Internet was cut off, and the living people awakened their superpowers, flew into the sky and escaped to the earth, and even carried axes and searched for him on the streets. He is a low-level zombie with 900-degree myopia. He cannot catch up with people and cannot speak. If you want to live, you can only open a book and read to yourself—— When others awaken their powers, he rubs the generator with his hands; While others moved mountains and reclaimed seas, he built surveillance cameras and set up spring cannons; Others pulled a team to grab the territory, and he built a library of seven million books into a zombie fortress. The human said: "Does a zombie deserve to occupy the library?" Dalin didn't make any noise and pushed over a writing board: "How about you come in and get it?" He is the most educated among the zombies and the most skilled among the scholars. Until one day, there was a note in his pocket, with crooked handwriting—— "By the way, give it back to your sister."
