One year, there was a great drought in the world, and the land of mountain gods was in urgent need of heaven. The Tathagata knew that these two dragons knew the world very well, so he sent two dragons, Huang Qing and Erlong, to this world.
Soon, Huang Qing Erlong discovered that it was the second demon "ghost" that caused demons and grandchildren to spread around the world and set fires everywhere. It also uses magic to hide a kind of "fire" in everyone's heart, doing evil to each other and disturbing the cool world on earth, so many people worship it and follow it.
Huang Qing Erlong is determined to eliminate the evil of human beings and reform the right path of the world. They disguised themselves as two monks to dispel people's evil thoughts and heart diseases in the name of treating diseases and exorcising evil spirits.
According to legend, these two demons poisoned people and made them suffer from a strange disease. Only by doing something that harms others and benefits others can we temporarily alleviate the pain caused by the illness. Seeing the human suffering, Huang Qing Erlong in heaven came to the world disguised as a monk and sent people medicines made of cinnabar, pearls and seaweed. After adjustment, many people found their conscience and relieved their pain. The news spread like wildfire and people rushed to tell each other. Three months later, thousands of patients recovered and lived a normal life. People also said that two living immortals had come.
"Ghost" heard that someone had broken their spell, so he sent two of his men, crocodile essence and toad essence, to find out the truth. Toad essence is full of evil and tricks. He came to the monk's place dressed as two patients with the naive crocodile essence. Toad spirit saw two monks sitting in the shade of a tree emitting blue and yellow lights, and knew that the other one was a miracle, so he had a plan. He told the crocodile that they were two little gods, so don't take it to heart. Let the crocodile sit there and rest. He can take them back by himself. Crocodile essence is furious, and toad essence can't take all the credit. So he showed his true colors, opened his hay cutter-like mouth and pounced on the two monks.
The two monks knew that two goblins were coming, but they kept silent. When they saw the crocodile essence suddenly show its true colors, one of them aimed at the crocodile and sloshed a marble-sized dragon ball, then knocked it to the ground. Seeing that the crocodile was in bad condition, he turned over and tried to escape. Another monk turned his hand and grabbed its brains and broke them. However, the toad spirit took this opportunity to escape and told the "ghosts" that Qinglong and Huanglong were saving lives.
The "ghost" was furious and personally brought 50 thousand demon soldiers to challenge. Qing and Huang Erlong told all the cured people not to come out, so they rode in the clouds and faced the "ghost" in the air. Qing and Huang Erlong used their magical powers to fight the demon soldiers for seven days and seven nights. Seeing that there are fewer and fewer demon soldiers, the two demons discuss a vicious idea. The two demons arranged their demon soldiers in two long snake-shaped dragon arrays, north and south, and slowly squeezed into the middle. Everywhere they went, everything turned to scorched earth. They tried to burn green and yellow dragons and people.
Huang Qing Erlong has been fighting the demon warrior for days and nights, exhausted. When they saw the evil intention of the "shadow", they turned into two cold yellow rivers, facing two fire dragons respectively, regardless of their own safety. When they came into contact with the "dragon", the fire met the water, which stirred up a huge whirlpool and dragged the demon soldiers into the river one by one. After three days and three nights, the two "big dragons" gradually crushed the "dragon" with their huge bodies. Destroyed the devil, the two dragons also exhausted their vitality and gradually embedded into the ground, forming the present Yangtze River and Yellow River.
To this day, the descendants of the Chinese people on both sides of the Yangtze River and the Yellow River are still multiplying by the river.
