Lu Yuanzheng (played by Li Cangmao) is the founder of the Lu Foundation, and the biggest knot in his life is that his beloved wife died in an accident in his early years, so he invested in the research and development of the latest metaverse virtual world for scientist Lao Liu (played by Cheng Zhen), hoping to return to 1995 in the metaverse and live with his wife Yu Jiao (played by Mu Lan) again to make up for the trauma in his heart.
