The final battle of the Silver Dimension begins. This time, it will be harder than all the previous battles combined.
The heroic teams must give more of their powers to stop Ye Si Ti from dominating the Silver and Iron Dimensions. But the battle turns disastrous when Ah Xiang emerges as their enemy, under her father's control. Eventually, they manage to gain victory with unexpected interference from Xia Tian (the last protagonist of The X-Family).
In a one month flashforward, Xiu and Ah Xiang have settled down in the Iron Dimension. Meanwhile, everyone in the Silver Dimension sets off to find their own paths in life: Zhao Yun goes on a journey to re-discover his charisma again; Zhang Fei regains his wealth after becoming obsessed with share and now owns a joy-stock company; Ma Chao and Huang Zhong open a surfer equipment shop together. Gan Ning's color-blindness is cured. Xiao Qiao and Zhou Yu are engaged. The Nationwide School Union is divided in three kingdoms by Cao Cao, Sun Quan and Liu Bei (with assistance from Zhuge Liang); thus officially form the legendary kingdoms of Cao Wei, Dong Wu and Shu Han. Guan Yu is finally reunited with Diao Chan after she went missing in 37th Round.
