The Six Prefectures of Zhongbo were ceded away in surrender to the external enemies, and Shen Zechuan was taken into custody in the capital, reduced to *a drowning dog loathed and condemned by all. Xiao Chiye followed the scent of the furor and made his way over. But instead of setting others on him, he kicked Shen Zechuan with his very own leg that rendered the latter an invalid. Who would expect this invalid to turn around and bite him in a counterattack until he was all drenched in blood?

I want to conquer that insurmountable peak. I am going to fight for myself.”

1v1, HE, HE, HE.
