"Bright Sword" is the first episode of 17, when Wei Dayong went out to deliver letters and was robbed by bandits in Heiyunzhai. The second master of Heiyunzhai attacked Wei monk, killed Wei Dayong and had Wei Dayong's head cut off and hung on a tree to pay homage to his brother who was killed by Wei Dayong.

In the seventeenth episode, all the people in the independent group communication class were sent to deliver letters. It happened that an urgent letter needed to be sent to HQ as soon as possible. Li Yunlong asked monk Wei to deliver letters, and Wei Dayong rode to HQ alone. As a result, he met someone from Heiyun Village halfway.

Kong Jie surrendered to Heiyun Village, but Heiyun Village hesitated to join the Eighth Route Army. The second-in-charge Bobcat took people to rob the road and wanted to grab more money before joining the Eighth Route Army, which happened to stop Wei Dayong from delivering letters to HQ.

Wei Dayong didn't want to clash with the bandits in the Black Cloud Village, but the bandits didn't care about Wei Dayong's oceans at all. Wei Dayong could only kill the bandits in the Black Cloud Village out of self-protection, but he didn't expect the two bobcats to ambush Wei Dayong on the mountain.

Bobcats shot Wei Dayong seriously, then killed Wei Dayong directly with another shot, and had Wei Dayong's head cut off and hung on a tree to demonstrate in memory of the bandits killed by Wei Dayong.
