In My Senior Year of High School, I Became a Quasi-Sage.

[Urban Invincibility + Return of the Ancients + Awakening of the Gods + Fast pace + Extremely refreshing writing] Chen Du failed to cross the tribulation and was plotted by Heaven. He returned to the senior high school classroom from the wilderness. The whole class was laughing at his monthly exam results. No one knows that he has lived in the ancient world for 18,000 years and is only one step away from becoming a saint. Got 16 points on the math test? Backhand, he uses the variational method that only graduate students can use to teach teachers how to behave. Provincial competition champion questions? The answer is given in three seconds, and the three solutions will convince the audience. The school bully blocks the door? One look made him kneel down on the spot. Chen Du originally wanted to keep a low profile and rebuild his education, so he helped the school beauty deal with a few monsters that were following her. But when he returned to Blue Star, he discovered that there were too many things hidden in this world that shouldn't exist—— Blue Star is no ordinary planet at all. It is a cage used by Heaven to imprison the gods of the prehistoric times. At the bottom of Kunlun Mountain, the Demon Saint was penetrated by chains. Under the glacier, the corpse of the great witch will not rot for thousands of years. Even the monkey that caused havoc in the Heavenly Palace has been sleeping here for a hundred thousand years. Now, the seal is loosening. And he is the only one who can break the cage.
