yang jian minking around

Yang Jian immediately flew out of the city, entered the Shang camp, and landed on the canopy of the Mo brothers' tent. Mo Lishou saw it and took it in his hands. He looked at it closely but was disappointed to find no sign of its having devoured anybody.
Late that night, the Mo generals drunkenly entered their tent and col- lapsed into bed. They were soon asleep and snoring like thunder. Yang Jian saw his opportunity. He jumped out of the bag and tried to get hold of the weapons hanging on the tent frame. As he grabbed the Universe Muddling Umbrella, he knocked the other two weapons onto the floor. The noise roused the four generals, but in their drunken stupor, they as- sumed the weapons had fallen because their hooks were loose. They carelessly picked them up and hooked them back onto the tent frame then fell back into sleep.
Yang Jian flew to West Qi City and gave the umbrella to Jiang Ziya. Nezha and his brothers came forward to inspect it as Yang Jian returned to the Shang camp. He crawled back into Mo Lishou's leopard-skin bag.
