There is no exchange in the mall, no punishment for erasure, only a closed-loop connection where everyone is prosperous and everyone loses. The two worlds are facing the same wilderness. Lin Sui, an orphan from the ancient dynasty, and Su Jin, a wasteland survivor, are bound by the symbiosis system: all the original materials from the ancient world are sent to the wasteland for life, and all the artificial materials from the wasteland are fed to the ancient world for survival. The two stayed together across time and space to fight against evil and weather the cold, supplying each other with hope and coexistence, and finally ushered in the rebirth of both worlds.
Intention: To coexist in desperate situations, help each other to overcome the crisis, and go both ways to gain new life
