MTL - The Book of Troubled Times - Chapter 245 is this pig's head yours

Xiaya reincarnated in the Dragon Ball Universe as a Saiyan 12 years before the destruction of Planet Vegeta. Watch him as he creates the strongest legend of Dragon Ball World from the beginning.

Luo Wencheng made a deal with a certain existence and went back in time to ten years ago, when he had just been released from prison, still young and healthy, not yet pushed to the breaking point by Luo Wenjun and not yet used by him as a prop to test drugs for profit until his tragic death.

This time he was going to trample Luo Wenjun underfoot.

The first priority was to steal Luo Wenjun’s future backer from him.

- Description from Novelupdates

“monarch of entropy” introduces a cosmic entity of immense power, whose eternal existence was once defined by passive observation. Everything changes when a surprising connection ignites a spark of curiosity and a yearning for interaction. As this King explores his evolving desires, his colossal abilities begin to influence realities on an unimaginable scale. This is the story of a powerful ruler's journey from detached observer to active participant, where every decision, no matter how small or whimsical, creates ripple effects across the multiverse, leading to a series of grand, and sometimes inconvenient, adventures.

You thought being reincarnated as an extra-side character was bad? Imagine being thrown into the body of a villain who is disowned by his own family and discarded by the author.
