Helian Entropy, a prodigy in the physics department, unexpectedly awakened and found that he was actually the Lord of Reincarnation in charge of the "Reincarnation Entropy Reducing Instrument". He understood that the essence of reincarnation is actually the entropy reduction process that goes against the second law of thermodynamics! By filtering memory information through the "Maxwell's Demon" mechanism (actuated by information entropy theory), he compressed his life experiences into qubits and stored them in his soul. Questioning the fate of reincarnation, he discovered that the paradox stemmed from a misunderstanding of thermodynamics. Working with the quirky assistant Mai Xiaowei and the fatalistic physicist Xue Ding, Helian Entropy uses statistical mechanics to calculate the probability of reincarnation, uses information theory to reconstruct memory encoding, and finally establishes the "Reincarnation Information Conservation Protocol". In the vortex of reincarnation where entropic light flows, he writes a growth epic that subverts cognition and is full of thermodynamic romance and life philosophy.
