Taking Exams Across Infinite Worlds from the Start: Survival Means Grinding!

[Squishy powerhouse + Eastern mythology Infinite Flow + Standalone exam-worlds + Natural disasters + Play the pig to eat the tiger + Power fantasy + No CP + Apocalypse]

Shi Zhen, a top student among top students at a prestigious 985 university, is a clinical medicine major. By his third year, he has already secured a recommendation for graduate school and the favor of his dream advisor. His future looks incredibly bright.

But one day, an ordinary surgical exam is altered into a fight to the death, and an exam world suddenly descends.

The strong prey on the weak. It's kill or be killed.

As the honors he'd worked so hard for vanish like mist, and his once-bright future grows dark, Shi Zhen looks at his two legs that can barely handle a hop, pinches the meager two ounces of meat on his thin frame, and without hesitation, smashes himself to death to start over.

Good news: He didn't die.

Bad news: He can't die.

Just as his top-student drive fades and his will to survive crumbles, the cheat System comes looking for him on its own.

Cheat on! Have fun!

With a cheat, maybe I can just barely manage to stay alive.

From then on... from then on, Shi Zhen wields a skill tree, beats up examiners, drains all the energy from the entire continent of the exam world, and ends this exam that butchers college students...

(The above is Shi Zhen's fantasy after his fighting spirit reignites.)

Before any of that, he has to figure out how to use his System, which faints after saying two sentences and claims to be only three years old. It's ridiculously easy to push around...

Note: This is a power fantasy! Absolutely a power fantasy! I'm doing my best to keep the logic solid alongside the wish fulfillment, and I'll fix any bugs as soon as I find them!

No CP. Male and female characters may appear, and could be good or evil. I guarantee there will be no male-gaze content.

The male lead isn't a cold-blooded lone wolf. He has principles and independent judgment, as well as friends and partners.

The myths have been adapted, and the dynasties are mixed up.
