Zang Fengxing is a martial arts juvenile cartoon jointly launched by Shuang Shan Film Co., Ltd., a subsidiary of Beijing Chenming Film and Television Culture Media Co., Ltd., and Kate Animation, a subsidiary of Beijing Kate Century Media Co., Ltd. This cartoon mainly tells the story of intrigue and enmity among various factions and individuals in the Jianghu, with the rumors that four sects are constantly being killed, "the demon knife is resurrected" and the growth of juvenile Peilie as the clue. In the seventh year of Cheng Xuan's reign, the demon sword that once plagued the East China Sea reappeared, and all the major sects in the Jianghu were hit hard. The world only regards "the evil of the demon knife" as an innocent rumor. Pei Lie, an ordinary blacksmith, was ordered to send his sword to Shuiyue Tingxuan, which coincided with fierce fighting. Pei Lie bravely saved him and fled in the rain with Shui Yue's disciples. At the same time, the four sword gates in the East China Sea gathered in Lingguan Hall to encircle the demon sword. The people who wreak havoc in Shuiyue Pavilion have something to do with the demon knife. Can the four sword gates destroy the demon knife in one fell swoop?
