One Piece: Unreal Adventure - Chapter 19: Improvement

He was supposed to transmigrate to a magic world, but due to an accident, he ended up trapped in a massive library. The system assigned him a task: for every book he read, he would be rewarded with mana stones, until he finished reading all the books. A trillion years later, Daniel finally finished the last book! [Ding, detecting that the host has finished the final book. Calculating system rewards.] [Ding, reward calculation complete. Dispatching rewards. The total number of mana stones the host has accumulated: 99999999...9999.] “Damn, am I that rich now?” [Ding, detecting that the host has completed the task. Loading world...] ... Goddess of Fate: “Daniel, my divine realm needs expansion. Could you sponsor me with some mana stones?” God of Storm: “Daniel, the divine punishment is about to descend. Could you lend me some power to help me get through it?”

Qiao Chen was mysteriously transmigrated to the interstellar era. As an adult from his original world, he was forced to grow up all over again in this new one. Now, out of nowhere, he was requested (forced to take on) with the inexplicable task of jumping from world to world to save the high general’s soul.

Throughout his journey, Qiao Chen finds that these worlds and bodies he’s jumping in and out of are his previous reincarnations. Whether or not these all culminate into coincidences or a predetermined destiny, there’s things that must be done while completing the main task:

-Avenge his past life

-Take revenge

-Fulfill past regrets

-Realize those lost dreams

-Make up for past failures

Since God has given him these opportunities to rewrite his fate, why wouldn’t he be pleased to start-over?
