Li Shengxia transmigrated back to the Tang Dynasty with a System packed with cutting-edge technology. Using his own hands and knowledge, he continually influenced those around him. As his influence spread, life grew better and better. People felt that a few decades had lifted their lives from hell to paradise, so Li Shengxia came to be known as an immortal descended from Heaven. Then one day, this immortal truly created a celestial artifact. Whether he returned to the Heavenly Court afterward, no one knows.
