After the final stage at Bayanbulak, Zhang Chi is invited to compete in a brand-new event, the “Muchen 100 Rally,” as the head coach of the team. The once “wild” racer now steps onto the international stage. Facing a completely new course filled with top-tier competitors, Sun Yuqiang and Ji Xing once again fight side by side with Zhang Chi. Powerful drivers such as Lin Zhendong are also invited to join, and a team built on top-level speed and shared belief is formed. However, Zhang Chi soon realizes that the true challenge does not seem to come from the race itself. Beneath the surface, tensions are rising beyond the track, casting uncertainty over their high-speed journey ahead.
