Anime Crossover: Natsume Takashi's Supernaturally Strong Adoptive Father

In his previous life, Si Jing was a scumbag who got chopped into mincemeat by his yandere girlfriend. When he opens his eyes again, he finds himself in Japan at thirty, a good-for-nothing who does nothing but hole up in a rental apartment and play video games, an overweight middle-aged shut-in.

Looking at his greasy figure in the mirror, Si Jing is just about to start his life over when good news arrives: he has awakened an extraction System that lets him obtain traits by killing things.

After killing the cockroaches in his rental apartment, he gains the trait:

[Flexible Chitinous Exoskeleton] (Can withstand static compression up to 900 times the user's body weight. The shell can deform and bend to dissipate heavy pressure)...

While downstairs throwing out the trash, he casually crushes a few ants:

[Exoskeletal Lever Strength] (The chitinous shell provides firm attachment points for the muscles. Using the limbs' lever structure, strength is increased fortyfold, and ground-dragging force can reach 100 times the user's body weight.)

But just as Si Jing decides this is an ordinary world and plans to farm traits, become the king of manual labor, and rise to the top, he doesn't expect what happens during a quick trip to throw out the garbage.

When he returns upstairs, six-year-old Natsume Takashi is standing outside his door. Only then does Si Jing realize this is a crossover anime world!
