No War At the Chivalrous Path - S2.E12

The inscription on the weapon reads Pozhen Bawang Qiang (The overlord's spear that crushes armies). Shaoyu is very fond of this reward. Tianming and Yue-er enters a chamber where there are many bronze soilders and a huge bronze god. Suddenly the bronze men began to attack them. Yue-er realizes that the bronze god knows their locations through the weight on the floor tiles. Therefore she stands on her tiptoe at the border of the tiles. Tianming pulls the key to the back door from the bronze god, and they manage to pass the chamber. Yue-er finds the key to be the ultimate weapon of Mohist, Feigong(No War).
