《IronFists》Ep1:episode 1
The head of the national army who held the Yunshanling was wounded and was transferred to the rear.

Twenty officers, led by Zhao Ying Zhang, gathered in the auditorium and enacted an "iron fist" project to eliminate the insiders. As a result, plans were leaked and 28 officers were arrested and killed. Both Guard Captain Yang Mu and underground party member Tong CanMou identified each other as spies. Both were overrelatedly trusted by Ma Rui and were reused. Tong CanMou decided to rescue Zhao Ying Zhang and others, but all of this was discovered by Yang Mu who was about to escape the cell.
