One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive.

When he woke up, Ji Que traveled to a dangerous world where fairy mountains collapsed and temples were abandoned.

Fortunately, he has a supernatural ability, which allows him to save his understanding and use it like banknotes.

The more understanding you accumulate, the more miraculous you can realize.

Comprehend “swimming”, you can swim as fast as a fish in the water, and you can swim up and fly on the ground.

After comprehending “The Analects of Confucius”, the knowledge will be integrated, and the muscle strength will increase exponentially.

After comprehending “The Book of Benevolence”, I have learned one more combat technique of “dividing people into two”!

After comprehending “Yi Xue”, I accidentally mastered a skill of “smashing the head into the body cavity”!

Comprehend “Xiaoyaoyou”, “Mozi”, “Taoist Tibetan”…
