After Li Jing locked up Nezha, he sent people to inform the people of Chentangguan that the Dragon King wanted to flood Chentangguan, so that the people of Chentangguan could run quickly, and at the same time mobilized crossbowmen to be stationed on the seashore to strictly guard against the East China Sea tribes.

Li Jing arranged these two things, and called the housekeeper and said, "Butler, you go and tidy up now, and escort the lady and young lady to the palace of Chaoge Wucheng." After hearing this, the housekeeper asked, "General, what about you and the little master?" Li Jing said: "I am the chief soldier of Chentangguan, and I should only live and die with Chentangguan." Nezha knows the Five Elements Escape Technique, even if the time comes, the Dragon King really floods Chentang Pass, he can also escape by water, I locked him up, I am afraid that he will not be able to do his best, go to the Dragon King. Don't persuade me anymore, go down and tidy up, and take Madame and Miss away. The housekeeper had to say goodbye to Li Jing and leave.

Li Zhenying learned that the Dragon King was going to flood Chentang Pass, and Li Jing was about to send her and her mother to leave Chentang Pass for Chaoge, but because she was worried about Nezha's safety, she stole the key from Li Jing.

When he got to the dark room, he opened the door. Nezha saw Li Zhenying knocking on the door and asked, "Little sister, where did you get the key?" Li Zhenying said: "Third brother, the Dragon King wants to flood Chentang Pass, and is going to send me and my mother away, I'm worried about you! Nezha asked, "That old loach is coming?" Li Zhenying said, "Not yet." Nezha said: "The old loach hasn't come yet, so he wants my whole family to flee, if not, I have to strike first." Nezha then recited a spell, and after a short time, the Qiankun Circle and Chaotian Aya flew to Nezha's hand.

Nezha said to Li Zhenying: "Little sister, go back and tell your father and mother, you don't have to run." Go kill the old loach now. After saying that, Nezha drove away.

When Nezha arrived at the beach, he thought about avoiding the water again, and jumped into the sea and headed for the Crystal Palace. When Ao Guang, the Dragon King of the East China Sea, returned to the Crystal Palace, he summoned Ao Shun, the Dragon King of the West Sea, Ao Ming, the Dragon King of the South China Sea, and Ao Ji, the Dragon King of the North Sea, to discuss the flooding of Chentang Pass.

The four of them were discussing the flooding of Chentang Pass, and Yaksha hurriedly came to report: "Nezha, who killed Li Gen and the third prince before, came in!" Ao Guang was furious when he heard this: "Okay! I haven't looked for him yet, he came to the door first." Immediately send my order, and order the nine princes to lead shrimp soldiers and crabs to defend against the enemy. Then he said to the three sea dragons, "The three virtuous brothers will go with me to capture the evil boy." Ao Guang and his third brother and nine sons went to the front of the Crystal Palace together, and saw Nezha killing shrimp soldiers and crab generals.

Said to the children on both sides: "Which of you is going to kill this evil boy?" The eldest prince said: "Father, I will kill him now to avenge the third brother!"

When the second prince and the fourth prince saw that their eldest brother had been killed, they were furious and killed Nezha together, and the two of them stabbed Nezha with guns from the left and right.

Nezha caught the spears of the two with both hands, snatched them from them, and stabbed them back. Ao Guang was sad and angry when he saw Nezha kill three sons in a row, and killed Nezha with the remaining six sons of the Dragon King of the Three Seas.

After fighting with Nezha for thirty times, he barely surrounded him. Nezha hurriedly flew and danced with the heavens, and suddenly turned the East China Sea upside down, and the ten dragons were also scattered, Nezha took the opportunity to make the Qiankun circle to kill the Dragon King Ao Shun of the West Sea, the Dragon King of the South China Sea, Ao Ming, the Dragon King of the North Sea, Ao Ji, the fifth prince, and the sixth prince.

He also used Chaotian Aya to defeat Ao Guang, the Dragon King of the East China Sea, and his seventh prince, eight princes, nine princes, and ten princes. Ao Guang and his four sons saw Nezha kill the eight dragons in a row, and hurriedly fled into the deep sea trench.

Nezha saw Ao Guang fleeing into the trench with his four sons, so he shouted to the deep ditch: "Old loach, you'd better stay in the ditch forever, if you dare to come out, I will definitely kill you and your four sons!" After saying that, Nezha used the Qiankun circle to mess with the sky, destroyed the crystal palace, and laughed away.
