After killing the red-scaled python demon in the cave, Hong Daoshi has been looking for the Yin Devouring King. He didn't know that the Netherworld King had been surrounded and suppressed by the Netherworld's troops and suffered a crushing defeat. Today, I happened to meet the Yin Devouring King, and he ran away again, and I don't know where I hid.

Undeterred, Master Hong continued to search for it using the technique of turning water, but did not find it. Hong Daoist turned to Professor Yang Shimo's Magic Mirror Room and Cloud Room for help, but he couldn't find the whereabouts of the Yin Devouring King. The Yin Devouring King's mana is so strong that ordinary tools can't find him. The longer the Yin Devourer King is hidden, the higher the spells he practiced, and the more difficult it will be to destroy him in the future.

In desperation, Master Hong Dao thought of the Zen Master Juedi of Hanguang Temple, who once made a spirit rune to bind the black hole, and with the help of the secret spell obtained by Hong Laodao from the ancestor of Cangjie, the black hole and the secret jar containing the Yin Devouring King were sealed together in the lower mountain col of Jinguang Valley in Banpo Village, Calamus Township. When Master Hong came to Hanguang Temple, the new abbot told him that Master Juedi had passed away, and Master Hong Daoist was so sad that he folded his hands and kept chanting the Buddha's name. Although he is a Taoist master, he recites Buddha for the highly respected Zen master Juedi.

"Before the death of the Ancestor, I was very worried that the Yin Devouring King would reappear in the world. After Shakyamuni Buddha entered and perished, 500 years was the period of the Dharma, the next 1,000 years was the period of the Dharma, and the next 10,000 years was the period of the end of the Dharma. With the development of science, there are fewer and fewer people who believe in Buddhism and fewer people who practice magic. If the Yin Devouring King returns to the world, who will be able to resist in the era of the end of the law? The ancestor had already calculated this matter and left a hand. In the mountain behind Hanguang Temple, there is a demon suppression cave, and there is a demon suppression mirror in it, which can be taken out to deal with the Yin Devouring King when you meet someone who is destined. The abbot said.

"Who is destined?" Hong Daoist asked suspiciously.

The first teacher did not say specifically. He only said four words: Guan Guan Ju Dove. The abbot said.

"What does this mean? Master Juedi let a water bird like a dove fly into the Demon Suppression Cave to get the Demon Suppression Mirror? The dove is a rare bird, where can I find it? Master Hong was puzzled.

The abbot took Master Hong to the Demon Cave on the mountain behind Hanguang Temple. The entrance to the cave is not large, and the cold air is bubbling outside. Master Hong carried the treasure knife and entered the Demon Suppression Cave, and saw that there were many skeletons placed in the cave, both human and animal. The abbot said that this was a demon and a monster that was subdued by the ancestors of Hanguang Temple and was imprisoned in a cave. Hundreds of years have passed, and some youkai have run out of energy and have died. There are also some powerful monsters that have sucked the energy of the little demon and are still alive in the cave.

The demon found that there was a living person coming in the cave, like a hungry tiger finding food, and stretched out his hands to grab the Hongdao Master, and wanted to absorb his yang energy. The Demon Suppression Mirror in the center of the Demon Suppression Cave emitted a strange light towards those restless demons, and the demons' hands were like electric shocks, and they hurriedly retracted. Master Hong came to the Demon Suppression Mirror, prayed first, explained the original situation, and wanted to take the Demon Suppression Mirror away. As soon as Hong Daoist approached the Demon Suppression Mirror, the Demon Suppression Mirror jumped in the air, no matter how Hong Daoist grabbed it, he didn't want to get close to the Demon Suppression Mirror.

Master Hong thought that the treasure knife in his hand was scaring the Demon Suppression Mirror, so he put the treasure knife at the entrance of the cave and turned around to get the Demon Suppression Mirror again. Suddenly, a strong light shot out of the mirror, and Hong Daoshi was pushed out of the cave by a powerful force. Hong Daoist touched his face and found that he was not burned, and it seemed that the laser or electromagnetic waves emitted by this Demon Suppression Mirror did not hurt people much. What kind of substance this strong light is, perhaps only Professor Yang Shimo has done experiments to know.

Master Hong returned to the temple and repeatedly pondered the meaning of the four words Guan Guan Ju Dove. The four characters "Guan Guan Ju Dove" come from the "Book of Songs, Zhou Nan, Guan Sui", which refers to the water birds that sing in Guanguan and live on the sandbar in the river. This is a love poem about a "gentleman's" quest for a pretty, slender "lady". Once the Demon Suppression Mirror is removed, the balance of yin and yang in the Demon Suppression Cave will be broken, and the demons will come out of the cave and endanger the world. The meaning of the Enlightened Master is that two people who truly love each other need to come to the cave and maintain the balance of yin and yang in the cave in order to take away the Demon Suppression Mirror.

Hong Daoshi thought of Hu Kehao and Lin Xueyi and told them his thoughts. In order to subdue the Yin Devouring King, Hu Kehao was willing to give it a try. They made arrangements for their studies and work, and made time for the weekend to come to Hanguang Temple. They first burned incense and worshiped the Buddha in the Daxiong Treasure Hall and prayed for the success of the mirror action. At the same time, they also secretly prayed in their hearts that they could come together in the future.

Accompanied by Master Hong Dao, Hu Kehao and Lin Xueyi came to the mountain behind Hanguang Temple and mustered up the courage to enter the Demon Suppression Cave. The pervert in the cave saw the beauty and was so excited that he was about to catch Lin Xueyi with his teeth and claws, but as soon as he touched her clothes, he was bounced back by a mysterious force. This was also the case when the demon caught Hu Kehao, but he was able to catch Hong Daoshi. After Hong Daoshi was caught, he kept driving him away with the treasure knife, and the demon didn't want to hurt him for half a point.

Hu Kehao and Lin Xueyi don't have spells, why can't the demons approach them? It turns out that they study and work in colleges and universities, are infected by the spirit of physicists, are blessed by great scientists such as Newton, Einstein, Maxwell, etc., and have a lot of knowledge in optics, thermodynamics, electromagnetism, relativity, quantum mechanics, chemistry, biology and other aspects.

Hu Kehao and Lin Xueyi approached the Demon Suppression Mirror together, they were very nervous and scared. Hu Kehao gently stretched out his hands to the Demon Suppression Mirror, for fear of alarming him. Just when his hand was only a few millimeters away from the Demon Suppression Mirror, he thought that the mirror could be caught with his hand, but who knew that the Demon Suppression Mirror suddenly jumped up and flew into the air. Hu Kehao grabbed it with both hands, and the Demon Suppression Mirror kept dodging in the air, unable to touch, so he had to retreat, and the Demon Suppression Mirror stood firmly in the center of the Demon Suppression Cave.

Lin Xueyi slowly approached the Demon Suppression Mirror again, and when her hands were only a few millimeters away from the Demon Suppression Mirror, Lin Xueyi was worried that the Demon Suppression Mirror would jump up again. Her hands froze, and the Demon Suppression Mirror stayed there honestly. After waiting for a while, Lin Xueyi grabbed the Demon Suppression Mirror with lightning speed, but the mirror still didn't move. The Demon Suppression Mirror was finally caught by Lin Xueyi, and she felt a burst of joy in her heart.

Lin Xueyi wanted to lift the mirror with both hands, but the mirror didn't move at all. She shook it with all her strength, and the Demon Suppression Mirror seemed to have taken root, still not moving. Lin Xueyi had no choice but to retract her hands, but her hands were like glue, and they couldn't be removed from the Demon Suppression Mirror. Lin Xueyi was in a hurry, and tears fell. Hong Daoist held the treasure knife and forced the Demon Suppression Mirror step by step, and the Demon Suppression Mirror seemed to be very afraid of the treasure knife in Hong Daoshi's hand, and let go of Lin Xueyi's hands.

"I see, it could be so. The Demon Suppression Cave is full of demons and monsters, and the Yin Qi is very heavy, since the Demon Suppression Mirror can restrain the demons, it must have a very strong Yang Qi. That being the case, then the same sex repels each other, and the opposite sex attracts. So when I and Xiao Hu took the magic mirror, it was ostracized and jumped high. When Kobayashi took the magic mirror, not only did the mirror not jump away, but it stuck firmly to her hand. It seems that this is indeed a magic mirror full of 'evil spirit'. I think it's better for both of you to pick it up at the same time, and you should be able to take it off. Hong Daoshi said.

Hu Kehao and Lin Xueyi thought so, they held hands, worried about each other's safety, and had the same mind. They approached the Demon Suppression Mirror together, Hu Keha stretched out his left hand, and Lin Xueyi stretched out his right hand. When the two hands were only a few millimeters away from the Demon Suppression Mirror, the Demon Suppression Mirror did not fly away. They held the Demon Suppression Mirror with both hands at the same time, and released it at the same time, and the Demon Suppression Mirror did not stick to their hands. They held the Demon Suppression Mirror with both hands again and gently picked it up without any resistance. They turned around, holding mirrors, put their arms around each other's waists, and walked towards the entrance of the Demon Suppression Cave.

"We took the Demon Suppression Mirror away, will the demons in the cave escape?" Hu Kehao asked.

"I don't know, let's try first." Hong Daoshi said.

As soon as Hu Kehao and Lin Xueyi walked out of the entrance of the Demon Suppression Cave, a monster ran out, and Hong Daoshi raised his sword and forced the demon back. Hong Daoist took a few steps back, and the demon was about to come out again. It turns out that there is a conservation law between heaven and earth, and if you take away a thing, you have to put it back, and Hong Daoist had no choice but to put the treasure knife in the original position of the demon suppression mirror in the demon suppression cave, so that these demons did not dare to act rashly. From this point of view, these demons are stupid. When they go out, they should pretend that they can't get out, and then come out quietly after they are far away. No way, they're monsters, and no one has the wisdom to come up with these simple schemes.

Taking out the Demon Suppression Mirror, under the guidance of the abbot of Hanguang Temple, they illuminated the hiding place of the Yin Devouring King. It turned out that this Yin Devouring King was hiding in the stone Buddha temple, pretending to be a bodhisattva in the temple, enjoying the incense offerings of the men and women, and his energy and mana were further improved, and the difficulty of dealing with him increased.
