Siheyuan: As a Level-Six Fitter, I Toy with the Courtyard's Troublemakers

[A Little Ruthlessness + Technical Skills + No Goody-Two-Shoes + Cathartic Face-Slapping + Everyday Life]

Li Guangjin transmigrates to 1962 and starts on hard mode: his parents are dead, his stepmother has been driven to death by the courtyard's pack of scoundrels, and a self-righteous busybody has even stolen his father's pension.

Luckily, he awakens a System.

From then on, the steel mill gains an all-around genius, and the courtyard gains a living demon.

A contest of technical skills?

While others are still striving to become first-grade workers, he handcrafts precision parts from the start, stunning the entire factory!

With a scalpel in his left hand, he's the head of the medical department. With a wrench in his right, he's a seventh-grade engineer!

He even builds a fuel-powered motorcycle by hand and modifies electric fans, living better than the factory leaders.

A showdown with the scoundrels?

Jia Zhangshi has a foul mouth? No! It's not foul enough. She needs a bucket of slop to fight stink with stink!

To outsiders, he's ruthless and merciless. He doesn't just slap them in the face, he crushes their spirits, grinding the scoundrels' pride into the dirt.

At home, he's a doting big brother, spoiling his two little sisters rotten with braised pork, White Rabbit candy, and pretty floral dresses made of dacron!
