MTL - This Omega is Fierce and Wild - Chapter 15 initial training

Cthulhu Gonfalon is a story about a man who woke up in another world. After a drink over his loss in a game, Sui Xiong ended up in the middle of the sea. Surprisingly, he now found out he no longer existed in a human shape but in a spirit state without any flesh. In order to survive and find a way to return to Earth, he then searched for a body to accommodate his spirit. After several confrontations with some creatures under the sea, he decided to settle for a jellyfish flesh. This Jellyfish was extraordinarily huge. With its tentacles, it caught others’ spirits to nurture its own power. In this world, Sui Xiong wasn’t only matchlessly powerful but he also had an ability to cast magic. With this gifted ability and combined with his knowledge from the civilized world on Earth, he could help a deceased person resurrect, change a person’s look, and do tons of other crazy things that he didn’t know.

He was the youngest guru of martial arts as well as the perfect Mr. McDreamy of the most girls. He had mysterious absolute touch, clear-sighted observation ability and various outstanding talents.

A normal guy gets hit by a truck and isekai'd. Why? Because trucks are apparently some cosmic loophole. He decides to be a dungeon, because it sounds weird and interesting to be one. Is it? Let's find out.

Xia Zhijun got the title ‘study god’ after scoring first place in the whole city. He’s the model of a good student in a teacher’s eyes: good grades, good manners, and quiet. When he wasn’t smiling, his entire body emits a cold abstinence aura. The girls only have the guts to look from afar and not get close.
Later, it was rumored throughout the entire school that even the study god would fight and hit on girls. Whoever dared to provoke his girl, he would teach you how to be a person at every minute. The night of the graduation ceremony someone saw him blocking Gu Siyi in the corner. He didn’t stop kissing even when she cried. He bit her lips and said in a raspy voice, “I’m going crazy…”
During college finals, Gu Siyi almost bursted out crying, “I’m such a failure. I won’t be able to find a good job in the future…And if I can’t find a good job, I can’t provide for myself…”
Xia Zhijun played with her pink earlobe and remarked, “I’ll take care of you.”
After they graduated, Xia Zhijun created a research company and Gu Siyi became the boss’s wife.
The commercial rocket, “Star of Siyi” was successfully launched. So everyone knew that the new technology superstar, Xia Zhijun has a wife who he spoils a lot.
