Zombies Are Coming: Transform into Skynet and Kill Through the Apocalypse

[Pseudo system + non-Madonna + zombies + Skynet terminator + no harem + protagonist not invincible + survival] Zombies are coming around the world, and the civilized order is on the verge of collapse. A few people on the verge of death have awakened their powers, but I discovered that I can make various robots. See how I can mechanically ascend! PS: This is my first time writing a book. Please bear with me. The meaning of the pseudo system is that the protagonist is Skynet and does not need to cover up a system shell, but the pseudo system was written to prevent conflicts.
