Strongest Survival by Otome Game’s Heroine (LN) - Chapter Volume 3 3: Thundering Fame

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?

Expect some:

Cold war era techs.

Super battleship with advanced electronics, propulsion, and fire control systems?
Helicopters?
Missiles?
Modern medicines and equipment?
AC-130?
A nuke?
Challenger or Abrams or Leopard?

Everything!!!

PS. Cover not mine, I just found it on google.

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…

Li Huowang was incapable of making up his mind. Was he in a hospital or in a fantasy world, struggling to survive? Both sides claimed that they were real and that the other is nothing more than a hallucination.

Follow Li Huowang on his adventure as he tries to make sense of what is happening to him. Explore a world full of bizarre cultivators and eldritch horrors as everyone tries to survive in it.

Official blurb from the raws: The bizarre path to the heavens, the abnormal Deities and Immortals. Are they real? Or are they fake? Li Huowang is unable to differentiate between the two in his confusion. But that’s not all that is causing him to be unable to differentiate the two. There was also his own illness, a debilitating one.
