My Entire Class Was Summoned to Another World except for Me - Chapter 148

Yu Mengruo transmigrated into a Zerg.
The good news is that he is a rare male with special privileges, and he also has the golden finger as standard for traversal.
The bad news is that the Zerg is a strong race, and the original owner just failed the promotion and was abandoned by the family. Within three days, within a very small range of options, he must choose a female partner with a worrying comprehensive score. The siege of marriage.
Yu Mengruo left his partner’s position to the desolate Bai Yueguang after a brief period of ignorance.
Bai Yueguang, who the original owner could not ask for, was a military female from humble background but self-improvement. Due to serious injuries that were difficult to cure, she could only be discharged from the army’s high position and became a defective product that was criticized by cold eyes.
When the once sharp sword was covered with dust, Yu Mengruo (thinking to himself) appeared as a radiant savior and stretched out his hand to the female worm in desperation.
Female worm: Is it to avenge my original rejection? 【Heart is like ashes.jpg】
Yu Mengruo: Nonsense, I am the reward for your hard work.

Although the copywriting looks like a favorite, it’s just a wild cat master who has not been domesticated and decided to give the stupid shit shovel a chance to get close to his story. The author thinks that it is mutual favor and two-way healing, but maybe readers will think that it is favored? Anyway, it’s not attacking the favor, it’s not attacking the favor, it’s not attacking the favor, and the important things are said three times!

- Description from novelbuddy

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?
