Re:Ant Lord - Chapter 84: Private chamber

Akira Kisaragi traverses into the Bleach world, unlocking a check-in system.He initially thought that by checking in daily, he could become stronger, soon become the Captain-Commander, join Division Zero, punch Yhwach, kick the Soul King, and marry Unohana...However, the system's style wasn't quite what he had imagined.〈 Check-in complete, obtained Genryūsai Yamamoto's secret roasted sweet potato! 〉〈 Check-in complete, obtained exclusive attribute: King of Normal Attacks, effect... 〉〈 Check-in complete, obtained Retsu Unohana's... 〉Akira's eyes suddenly lit up!“Seems like this might not be so bad after all!”

One system connects two worlds. Wu Ye, a timid and unambitious rich second-generation, was suddenly thrown into an apocalyptic world of zombies, equipped with a strong golden finger. To flee, or not to flee?

Qin Wuhua, a cold-faced special forces soldier, with his comrades betrayed by his superiors, showed him one night of “good will.”

To eat, eat, or eat? (Ye: What about the other options we talked about?! Qin: Be good. Ye: …..)

- Description from Novelupdates

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?

Cold war era techs.

Super battleship with advanced electronics, propulsion, and fire control systems?
Helicopters?
Missiles?
Modern medicines and equipment?
AC-130?

Everything!!!

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

SSS Beast Apostle System and Survival Racing in Apocalypse.

When the aliens invaded earth, they didn’t come for its resources as many doomsayers had proclaimed throughout the years.

Instead, they came for fun.

They came, flattened earth’s biggest cities and turned the world into a planet-sized stadium for their civilization.

The sport?

Survival Racing.

Ferocious alien beasts were unleashed upon the ruins of the world along with thousands of alien death-row fugitives who were only told one thing: Kill the humans, survive the year and regain your freedom.

Elliot was a survivor. He died right before he entered the final 15 days of the Games.

But as his consciousness began to slip away, a metallic voice rang out within his soul.

Mission failed.

Activating sponsor’s Boon: Reverse Time Walk.

Activating sponsor's Boon: Beast System.

Welcome to the Beast System. My name is Hawk, your AI.

EXCERPT from Chapter 1:

Elliot screamed in absolute exhilaration as he smashed his foot on the brakes, just enough to fully utilize the power of his ceramic brakes but not so much that his tires locked up. He went from two hundred miles an hour to forty miles an hour in a heartbeat.

He entered the sharp corner from the outside at the maximum entry speed and skillfully brought his car to the threshold of his tire’s grip.

SCREEE!!

He took the corner at record speed like a professional racer and then floored the pedal to the metal once more!
