After Lin Yuan, a genius who cultivates immortals, ascended to heaven, he discovered that the immortal world was not a paradise but an endless cosmic battlefield called "Heavenly Wall". His personal Taoism was deprived of him and he was reduced to the lowest level of "heavenly soldier". However, with his unique Taoist reverberation that has not been completely erased, Lin Yuan showed extraordinary value in a desperate situation. He was identified as a rare "Tao Thorn" and was absorbed into the "Sequence Zero", an elite secret force that dealt with the highest threats. From then on, he embarked on a thorny road to reinvent himself in a cruel war and explore higher power.
