Kai, a modern college student, stayed up late to finish his thesis on "Mechanical Principles" and died suddenly after drinking. When he opened his eyes, he was transported to the magical world of the parallel universe. When he woke up, he encountered a witch demolishing the village. He relied on military training to "turn left" to avoid magic, used a Huawei power bank to charge the "Iron Egg" of the mechanical wolf in the ruins, and accidentally bound the "core of time and space" that can be traced back and analyzed.
Others rely on combat experience for rebirth, but Kai relies on modern knowledge to reduce dimensionality: using high school chemistry to mix magic fuel, and changing the muzzle of the Iron Egg into a Sky Monkey launcher; building a force relies on "eating hot pot every Wednesday" to unite people's hearts, even the cold witch scientist Li Mei is Being bribed by his hot pot ingredients, he changed from "I want to dissect you" to "Let me read the paper"; even the villain Planet Eater was confused by him - this guy not only dismantled an alien energy station to use as a power bank, but also complained that "you, this rogue software in the universe, has no ethics review"!
Tie Dan has evolved from Tie Hanhan who only knows "Didi" to a conspicuous bag with earthy BGM and "Kaipai certified" stickers. He even fissioned into two small iron eggs, one to fight monsters and the other to deliver snacks to Kai. Lina and Kai teamed up to magically modify the machine and changed the time and space core notification sound to "Alipay has received 1 million." The two chatted about the parts all afternoon, like college students rushing to due.
Until Kai discovered that rebirth was a cosmic experiment and that he was reincarnated for the 99th time, Tiedan degenerated into a mini version to save him - he still carried the little Tiedan through the void corridor: "What are you afraid of? If you win, you will get the magic hot pot. If you lose, you will have to go back and start over!"
Since then, the Wizarding World has had a stupid leader.
