She was a medical genius from the Noah Medical Academy as well as a drug producing specialist. After sleeping for three days, she had returned to the ancient era and become the loyal marquis palace’s ignorant and silly young miss.

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?
