But fate had other plans for him. He was mysteriously transmigrated into the world of cultivation, a place where strength reigned supreme and power could shape reality. In this world, Ye Tian embarked on a dark path... the path of demons. After trillions of years of cultivation, he ascended to the pinnacle of power, becoming the Absolute Demon, feared and revered across the entire cosmos. His beauty was angelic, but beneath that flawless appearance lay the heart of a ruthless killer... a demon hidden in the guise of an angel. Countless races trembled at his name. He was a cold-blooded, merciless force of destruction, known for slaughtering without hesitation. Entire worlds were laid to waste at his feet. His cruelty knew no bounds, and his reign of terror spanned eons. Yet, for all his strength and dominance, there was no satisfaction. Ye Tian grew weary of the endless killing and ruling. Standing at the top, alone and bored, life had become empty... a never-ending cycle of bloodshed that no longer stirred his emotions. But everything changed one fateful day. In the blink of an eye, Ye Tian found himself back in his old body, back on Earth, as if the trillions of years he had spent cultivating were nothing more than a distant dream. However, this Earth was not the one he remembered. The world had changed. A giant Tower had appeared... like something out of the fictional fantasy stories he had read in his past life. And just as Ye Tian began to grasp this new world, a system window appeared before him... [Connecting to the Tower.] *****
