There are two theories. The first one is the python spirit, which comes from "The Green Snake" and was brought by Fa Hai to practice his concentration. Fahai vowed to practice Buddhism, but he still lost to the demonic barrier of lust, and the black python in Xiaoqing's arms was the embodiment of Fahai's desire. The second kind of Dharma is the turtle spirit, which comes from the folk. According to legend, there is a turtle in the west, hiding under the lotus seat of Tathagata Buddha and listening to sutras. After listening to the sutras for several years, the turtle also learned some magic. When he took a break from the Tathagata Buddha's sermons and dozed off, he stole three of his treasures and ran to the mortal world, turning into a black and thick monk. He thought that he had strong spells and great abilities, so he named him Fahai.
Plot summary of "Green Snake": During the Southern Song Dynasty, people's livelihood was in a state of chaos, and it was difficult to distinguish between humans and monsters in the market. The majestic monk Fahai takes it as his duty to do justice for heaven, suppressing goblins everywhere to improve the people's hearts. After subduing the spider spirit disguised as a kind old monk, he disturbed the two green and white snakes who were practicing cultivation at the bottom of the West Lake. Because White Snake Zeng Yi saved Qing, the two became sisters.
The green snake and the white snake were bewitched by the spiritual light of the fairy Buddha beads and became enlightened. If you were in the world, curled up on the beam and peered into the world of mortals. The White Snake is better than the Green Snake, and he likes the handsome and honest Xu Xian. Xu Xian loves books and aims at fame, but Bai heart acquiesces. The cunning green snake only sings, dances and plays nonsense, and its snake nature has not changed. After a decisive battle with his inner demons, Fa Hai greatly increased his power. He realized that evil spirits were appearing in Hangzhou, and he went down the mountain with a Zen staff to eliminate evil spirits for the people with full confidence.
White Snake, already in love, chanted a spell to induce rain, and got acquainted with Xu Xian by borrowing an umbrella. After a severe plague caused by heavy rains, White Snake spent money to open the drugstore Baohetang, thinking that he would be able to live a stable life from now on. As time went by, Xu became increasingly smart and powerful. Coupled with the temptation of the green snake, pure love could not withstand the test, and Xu Xian had second thoughts.
