In the distant future, the world is under the shadow of the apocalypse. Fanfan pilots a mecha, fighting alone against Liang Chao, who commands natural disasters and seeks to rule the world. When the battle reaches a desperate impasse, Fanfan activates a device that summons across time and space, making contact with their 2018 self.
After learning of the crisis, the past Fanfan works to improve the mecha and find the weakness in Liang Chao's powers. Liang Chao, meanwhile, continues to amass strength and develops an even more powerful force of chaos. The decisive battle erupts, natural disasters ravage the battlefield, and Fanfan and Liang Chao clash fiercely.
At the critical moment, a mysterious force appears. It surges into Liang Chao's mind like a flood of consciousness, showing him the horrifying destruction of the future world under his rule. Shaken, Liang Chao decides to join forces with Fanfan. But the mysterious force continues to exert its influence, and both their abilities steadily weaken. At the same time, the future Fanfan and Liang Chao are also fighting, when suddenly their powers are drained as well.
Just as everyone is at a loss, space and time twist, pulling them into a vast vortex. When everything settles, they find themselves back before any of it happened. Fanfan and Liang Chao awaken from their dreams. Though neither knows whether it was all real, both decide to protect the present and never again let power and ambition control them.
