A concise summary of a Li Kui story from Water Margin 30~50

Li Kui went home to pick up his mother and went to Liangshan to enjoy a happy life. On the way, he encountered Li Gui who used his name to cut off the path and robbed him, and chopped Li Gui with a knife. After hearing that Li Gui said that he wanted to support his ninety-year-old mother, he did not kill Li Gui and gave him ten taels of silver. Later, he learned that he had been deceived and that Li Gui did not have a ninety-year-old mother, so he killed Li Gui and his wife escaped.

Li Kui went home to see his mother. Her mother had been blind because she had been crying for missing her son for many years. Li Kui lied to his mother that he had become an official and wanted to take his mother to enjoy the blessings. Carrying my mother on my back to Yiling, my mother complained that she was thirsty. So Li Kui asked his mother to sit on a big bluestone and went to get water for his mother. Unexpectedly, when he came back from fetching water, he found that his mother had been eaten by a tiger. Li Kui was filled with grief and anger. He carried a simple knife and killed four tigers including his son, mother, and tiger. He collected the remains of his mother's body and took it to a nunnery for burial.

"Black Tornado" versus "Langli Baitiao"

One day, Li Kui, Song Jiang and Dai Zong went to a restaurant to drink. Song Jiang said he wanted to eat fish, but the hotel happened to have none, so Li Kui went to buy it. Li Kui went to the riverside to buy fish from a boatman, but the boatman said he could not sell it until the owner came back. Li Kui got angry and jumped on the boat to grab the fish, but he couldn't catch fish and accidentally let all the fish run away. The boatmen would not give up, so they started fighting with Li Kui. These boatmen were no match for Li Kui. Zhang, the "Langli Baitiao" who just happened to come back, lured Li Kui into the water. Li Kui forgot in a fit of anger that he didn't know the nature of water, so he jumped into the water and choked, losing the power to hit people. Fortunately, Song Jiang arrived in time and showed Zhang Shun his brother's letter. Only then did Zhang Shun know that it was the famous Song Jiang. Later, Li Kui and Zhang Shun became brothers in life and death.

Dai Zong and Li Kui were ordered by Song Jiang and Wu Yong to leave Gaotang Prefecture and go to Jizhou to find Gongsun Sheng. One day I went to a plain noodle shop for dinner and learned from an old man that Gongsun Sheng was in Erxianshan, Jiugong County. Dai Zong went to see him, but was rejected by Gongsun's mother. Dai Zong asked Li Kui to go fight in the house, but Gongsun Sheng had no choice but to come out. He refused to go to Liangshan because his mother was old and Luo Zhenren would not let her go. Li Kui stole to Songhexuan at five o'clock and hacked Zhenren Luo with an axe. Luo Zhenren sent a white handkerchief to tease Li Kui. Dai Zong repeatedly begged, and Luo Zhenren sent a yellow scarf warrior to rescue Li Kui from Jizhou prison.
