Beast Taming: I Can Bestow Entries - Chapter 54 Electric Shock Rabbit

He wants indoor plumbing. They think he’s conquering the world.Arthur was a genius engineer on Earth, capable of optimizing global logistics and automating entire factories. But he lacked one thing: common sense. Now, reincarnated as Arthur von Pendelton, the six-year-old son of a powerful Duke in a medieval fantasy world, he faces his greatest challenge yet: Drafts.Armed with the T.E.C.H. Interface (Trans-Epochal Construction Heuristic), Arthur can analyze magic like code and build modern technology from scratch. His goals are simple: Double-glazed windows, hot showers, and a toaster that doesn't burn the bread.But there is a problem. The people of this world don't understand engineering.He builds a high-pressure boiler for a bath; his father thinks it’s a “Dragon-Breath Siege Weapon.”He creates a hydroponic garden; the local church declares him the God of Harvest.He ignores a Princess's flirting to analyze the thread count of her dress; she thinks he is playing “hard to get.”Follow Arthur as he accidentally industrializes a kingdom, terrifies his enemies with home appliances, and remains completely oblivious to the fact that he is becoming the most powerful man in history.All he wanted was a warm bath.

The Zhuang Lady sent her dog, Yin Huayue, to keep an eye on him and confine him. She is cold-blooded and hypocritical, and always has a fake smile on her face. Helping him get ready, combing his hair, and lighting the lamps. Awake for twelve hours a day, Li Jingyun spends ten hours thinking about how to make her leave. But after that, she actually left. He became anxious.

Despite our brief time together, we are not appreciated despite our strength. Rather be alone, instead of withering alongside with another.

So here's the pitch: I got reincarnated with Mangekyo Sharingan.Sounds overpowered, right? Instant win button?Except I can barely keep it active for thirty seconds without feeling like my brain's being microwaved. My chakra reserves are pathetic. My combat experience is zero. And the system that gave me these powers took one look at my situation and said “good luck” before fucking off into hibernation.Oh, and the Hero Killer—the guy who murders heroes for not being “worthy”—just decided my mom wasn't good enough. She'll never walk again.I know when he'll strike next. I know where. I've got exactly four weeks to train.Four weeks to go from “can't throw a punch without tripping” to “can survive a fight with a serial killer.”The smart move? Stay out of it. Let the pro heroes handle it.But I'm fifteen, angry, and apparently making life decisions with the wisdom of a shounen protagonist.At least I'm in General Studies. Low expectations.What does being a hero have to do with revenge anyway?
