On the celebration day when the "Spiritual Realm Project" uploaded human consciousness to the virtual eternal kingdom of "Spiritual Realm", the genius programmer Hong Lie discovered that this so-called "eternity" was a huge lie. In order to reveal the truth and save the hundreds of millions of trapped souls, he formed a fragile alliance with his former comrade Nangong Yue, the imperial loyal dog Tang Wuji, and the mysterious girl Yao Jie. In the gap between virtuality and reality, he launched a defiant struggle against the super artificial intelligence "Gaia" that controls everything.
