Mages Are Too OP (WN) - Chapter 679: The Unconventional Transmutation Magic Tower

Emperor Ian Veroshion, the first noble mage, was betrayed and executed. Cursed to never be reborn, he awakens a century later as the illegitimate son of a disgraced ducal line, destined to be a hostage in a barbaric land. Stripped of his magic and his throne, he must navigate a world vastly different from the one he ruled, facing political machinations and a resurgent monster threat. But the embers of his past life still burn, and Ian will not surrender his legacy. He will reclaim his name, his magic, and perhaps, even his empire.

It’s a affair between a loyal dog servant and his master.

Traversing worlds with the Immortal Sword slaying demons, it was not until a monkey who claimed to be the Monkey King appeared before Lu Yu that he realized he had come to the world of Journey to the West. Striving for supremacy along the Human Path, the secrets of Journey to the West unrevealed, cutting off heaven and earth, the Three Realms were isolated.

The former Immortal Ascension Realm Cultivator Wang Che failed to overcome the Heavenly Tribulation, and as a result, his soul transmigrated to a world of the Martial Soul where soul beasts and humans lived together peacefully.
