Let's lay our cards on the table. Our Old Li is a top student.

After crossing the War of Resistance and awakening the cultural system, the noob Old Li became a top student in seconds.

If you learn mathematics, physics, and chemistry well, you won’t have to be afraid of killing the devils.

[Maximum level in geography: Explode mountains, dig gold mines, dig for mines, dig for oil]

[Chemistry max level: White Pellet, various poisons.] The gas bomb made the devil walk away.

Maxed out Mathematics and Physics: 56.5, 40 Fire, 107 Rocket Launcher, able to defeat the Japanese.

[Agriculture max level: improve grain types and provide enough white rice.]

A few years later.

Looking at the Eighth Route Army that was about to attack the palace, the devil cried out," I’m not afraid of anything, but I’m afraid that Li Yunlong is cultured.”
