Bai went to the blacksmith shop to buy a sword. He originally only wanted to buy one, but the owner only wanted to sell two swords together.Many bizarre whirlpools appeared on the Qiantang River.These whirlpools are magical tricks prepared by the toad spirits to swallow fishing boats and people.White Snake was flying over the river when he suddenly saw small whirlpools converging into a large whirlpool. Several fishing boats were sucked into it and were about to sink to the bottom of the river.White Snake comes to the rescue.Bai Suzhen realized that the whirlpool was caused by magic, and decided to go into the water to see what monster was causing trouble.It turns out that it is the frog-faced water snake's subordinates, the toad spirit and the clam spirit, who are causing trouble underwater.Feeling the call, the green snake also came to the riverside.Qing and Bai teamed up to rescue all the fishing boats.The two work together to fight off the toad spirit and the clam spirit.Qing and Bai asked each other why they were here.Bai Suzhen finally confessed to Xiaoqing that Guanyin Bodhisattva inspired her to go down the mountain to repay Xu Xian's kindness.After calculation, she knew that Xu Xian was in Qiantang County.Xiaoqing told Bai Suzhen that she stayed in the world in order to regain the power of the Demon-Suppressing Pearl, but what she saw was a smoky world, and she didn't know how to find strength.Xiaoqing was grateful for Bai Suzhen's life-saving rescue last time, and was convinced of Bai Suzhen's skill and virtue. Bai Suzhen also liked Xiaoqing's liveliness and straightforwardness.The two are sworn sworn brothers and are like sisters.And agreed that Xiaoqing would help Bai Suzhen find Xu Xian, and Bai Suzhen would help Xiaoqing find the power in the world.The defeated toad spirit fled to the bottom of the Qiantang River and reported to the frog-faced water snake who was recovering from his injuries. Because Green and White came to disrupt the situation again, he failed to capture the people on the river today to build the Ten Thousand Mirrors Forest.The frog-faced water snake was furious and vowed never to let Qing and Bai go.
