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?

Kael was a “rat”—a lowly stable boy in a frozen, brutal medieval world where Knights ruled with iron and Barbarians crushed skulls with bone clubs. His life was worth less than the manure he shoveled. That changed the night he butchered a Knight with a rusty dagger to pay a debt of blood.Chosen by the God of Slaughter, Kael awakens the Aether System. His cheat? The ability to project his soul into other worlds, live countless lives, and bring their powers back to reality—if he survives.But power is not free. It is bought with pain, time, and sanity.World 1: The Wild West. He spends a lifetime as “El Lobo,” a legendary gunslinger. He returns with the muscle memory of a master marksman and a 12-gauge shotgun. World 2: The Martial Arts Realm. He trains for decades as a Wuxia disciple. He returns with internal energy that can shatter steel.Now, as the Kingdom faces war and monsters surge from the dark, the nobles sneer at the servant boy holding a strange metal tube. They chant spells. They draw enchanted swords. Kael takes a slow breath. He racks the slide. Click-clack. “Parry this.”

Facing bankruptcy, a beekeeper crosses over into a magical fantasy world, gaining the ability to control bee swarms. Leveraging magic, he cultivates diverse mutant bee species: efficient honey-collecting bees, formidable combat bees, and entirely new bee species with extraordinary abilities.He explores this fantastical world, bringing back various nectar-bearing flora for cultivation, creating magical honey imbued with enchanting effects, and distributing it to all corners of both worlds. While he becomes renowned as the Honey King of his original world and an elite beekeeper, his fame also spreads in the magical world, where he’s known as the Bee Whisperer of the Black Forest.The latest edition of the “Black Forest Adventure Guide” specifically warns: “Never attempt to provoke him, or his bee swarms will not spare you! Don’t ask me how I know!”

There are 7 dimensions controlled by a Universal Government. Each dimension is governed by its own unique universal laws. There are a few things they have in common, there is always 1 the strongest and 1 the smartest. Except for the Universal Government, it’s forbidden to travel between dimensions. Interdimensional gates don’t close on their own and if left open, creatures that dwell in the darkness between the worlds will find their way through. Without warning, one of the dimensions disappeared without a trace. The remaining 6 in panic did all they could to find the reason why. They never found an answer. 12 years after the dimension vanished, a signal started appearing in the empty universe. Perhaps the answer is in that signal.Tsugi No Level
