The Legend of Qin (2007) : 2x5

Duanmu Rong tells Gao Jianli that she has checked all the water in the City, and somehow there's no prison at all. Ge Nie is prisoned, and Tianming is furious with the Mohists. Xuenv immobilizes him and put him into the room next to Ge Nie's. Duanmu Rong gives the Mohists leaders her unique pills that can resist any prisons for four hours just in case. At the daybreak Duanmu Rong is suddenly reminded of a poison called One Thousand Nights, the poison that never attacks unless it's exposed to sunshine. The poison became gas and the whole City is paralysed. Tianming feels painful because of the gas, and Ge Nie tries to teach him to resist. Wei Zhuang and Qin's armies began their attack.
