- Description from novelbuddy

In Academy City, magic and science coexist in an unwavering power struggle. Toma Kamijo, an academically-challenged student in Academy City, wields the power of the Imagine Breaker in his right hand, which allows him to completely negate all supernatural powers – as well as his own luck. When he happens upon a mysterious nun named Index, whose mind has been implanted with the Index Librorum Prohibitorum – 103,000 ancient texts banned by the Church – Toma’s luck is about to be pushed to its limits when he finds himself in the middle of a war he never expected!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

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.
【Lightning Protection Guide】
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!
