I've Already Confronted the Five Kage, and the System Just Arrived! - Chapter 351 - 352

The 5,000 years-old boy has resurfaced!In the distant past, young and foolish Asley flunked out of the prestigious Magic University… by failing an early exam that had a 100% passing rate until then. 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!

An 18-year-old poor college student tried to apply for a job as a tutor but his life almost ended as demons' meal. In his last breath, a mysterious woman gave him a strange power. When he opened his eyes he had turned into a demon with a system that would turn him into… A pervert.

Now he must lived with his dual identity as a model student named Ethan and an incubus named Damian.

I accidentally changed the whole world, the resurrection of the dead, genetic variation, recovery of the qi, mountain and seas reborn, land and seas expanded and evil spirits have started to appear.

Ghosts are now commonplace. Some people now have three heads and six arms. Some people have obtained martial arts techniques and ordinary people are now just cannon fodder.

Fortunately, I have acquired an ability which can make various items mutate.

books into martial arts or cultivation manuals,

fruits into precious treasures of heaven and earth or poison that you can only imagine and…

weapons, that can split the earth or gain sentience!
