The Bee Dungeon - Chapter 248: Battle of Bee and Spider

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?

Shortly afterwards, he accidentally created the immortality-granting “Drop of Eternity,” and upon consuming it, obtained an eternally lasting body.He devoted himself to researching magic for almost 5,000 years… after which he traveled in search of the world’s most mysterious Dungeon. Along the way, he happened to save a family, and then their town, from a monster attack. Before he knew it, he was hailed by the locals as a savior with ancient arcane arts and knowledge…While helping to rebuild the town, an opportunity came up for Asley to enter the Magic University once again, so he did. One thing led to another, and his initially normal journey got bigger and bigger — studying, adventuring, monster hunting, money-making, hellish training, uncovering conspiracies, saving the world, the whole nine yards!Thus began the adventure through the mundane and the insane of “Eternal Fool” Asley, his Familiar wolf-dog Pochi, and all their friends and enemies along the way!
