Starting with the Death Penalty, I Trade Myself in the Parallel World

Su Han traveled through the parallel world and found that the original owner had been framed as the murderer of the scientist who was researching controllable nuclear fusion in the Dragon Kingdom. He was directly sentenced to death and executed three days later. Just when Su Han was at a loss what to do, he suddenly awakened to a system that could trade with himself in the parallel world. At the beginning, he made a deal with himself as a detective in the parallel universe, found out the truth of the matter, cleared his grievances, regained his innocence, and successfully caught the murderer. Then he made a deal with himself in a parallel universe with highly advanced technology, and successfully obtained the key technology of controllable nuclear fusion, the proof of Goldbach's conjecture, and the design drawings of the lithography machine, which shocked the world's scientific community! He also made a deal with himself in a parallel world where literary and artistic works were highly developed, published One Hundred Years of Solitude and the Smiling Mona Lisa, and became the brightest star in the literary world. Many years later, Su Han stood on top of the world. Countless reporters were very curious, how did he achieve so many awesome achievements? Su Han answered humbly: "It's all based on my own efforts!" The self in the parallel world is also myself! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
