Under the wooden bridge, there was a life with red eyes lurking. There was a small pond with stagnant water. What kind of monster was lurking under it? Could it be that Mr. Yue’s sister’s strange disease was caused by it?

Before he could finish his thoughts, there was a loud bang, and the pond water wrapped in the mud rose into the air. Then a long yellow creature as thick as a human arm and about two meters long jumped out, and its head as big as a fist hit Lu Shangqin.

Lu Shangqin was not panicked at all. He opened his mouth and sprayed a mouthful of wine, which was full of puffs on the monster's head. Its body, which was sliding in the air, immediately spasmed, its strength disappeared, and his body was no longer moving forward, and he fell into the water with a plop.

After that, the pond seemed to have a pot, and the monster twisted his body violently in pain, broke the lotus leaf pods, stirring up the mud under the water. The originally clear pond water suddenly turned black, and the air was filled with a rotten smell.

Lu Shangqin sprinkled wine on the wooden bridge guardrail and looked at the monster struggling desperately in the pond under his feet. I walked to him. In addition to the stench, he smelled a fishy smell in his nose. He also saw clearly that the monster in the pond was actually a huge loach. No wonder no monsters were found in the pond, because loaches were fish living under the mud.

At this moment, President Yue was impressed by Lu Shang and Qin Wu, but I really couldn't understand how he had discovered the mystery of this place, so he asked respectfully: "Master, why did this kind of weird thing appear here?"

Lu Shangqin smiled and said, "I really don't know why it is here. As for why you see through this mystery, you have to start with traditional Chinese medicine. There is a leading doctor named Li Chuntang in the Qinggong Imperial Hospital. He is good at configuring and preparing sanitary, soup and pills with miraculous effects. He once arranged a decoction called "Tianhe San" to treat internal fire and attack the heart. The medicine is basically the blood of giant loaches."

"Traditional Chinese medicine divides life into two numbers of Yin and Yang. Yang over produces evil fire, and Yin over produces cold poison. Therefore, traditional Chinese medicine treats diseases as a process of regulating and balancing Yin and Yang. However, some lives are born with lack of yang numbers. For example, cold-blooded animals have only yin and no yang in their bodies. Therefore, in ancient Chinese medicine theory, cold-blooded animals are regarded as yin ghosts living in the yang world and having physical bodies. Ancient Chinese medicine said that loaches are evil in nature and fear light and like yin, but in order to avoid being frozen, they will inhale in Yang. As for the "source of yang energy" may be light, may be heating, but the most terrifying one is the spirit of warm blood creatures near it."

"Although the so-called three souls and seven spirits are the myths of practitioners, traditional Chinese medicine has a summary of spirit. Specifically, "spirit" belongs to the throat position. People who practice magic skills know this. Therefore, according to the theory of ancient Chinese medicine, when you approach a loach and breathe, the number of yang contained in spirit will be perceived by the dormant loach and quietly absorbed and used for your own use. Li Chuntang searches for a rare mud pond based on this theory, and then judges whether there are giant loaches by the biological signs around the mud pond."

"He found a pomelo in the grasslands of Beijing. The plants around it were barren. The land near the pomelo was scattered with bones of many dead animals. There were many beasts among the corpses of these animals. The corpses of some undecayed animals showed a mummy state, so weak that their bodies were only skin and bones. Occasionally, some rabbits and squirrels were old and had no agility that such wild animals should have. Even if the wolf fox chased the prey, they entered pomelo.

The land would be tens of meters around the ground, even the male wolf with red eyes was like this. So Li Chuntang put sulfur in the mud and then forced out a giant loach living in the mud. It was this loach that sucked all the Yuanyang energy of the surrounding creatures and turned this place into a place of death. Therefore, the larger the loach, the greater the demand for "yang numbers", which will naturally cause harm to nearby people and animals. The weakening that Mr. Yue's sister's body cannot be suppressed is due to the loss of Yuanyang."

"But the most feared loaches with extremely yin nature is sulfur. As long as the human body contains sulfur, loaches will be far away. So what I want you to buy firecrackers is the sulfur contained in it. Loaches are a kind of trick. Its blood is taken by some wizards and Taoists as magic tools for casting and preaching. Because the blood of loaches is extremely yin and cold, it can attract some unusual strange things. But loach blood is also an extremely mysterious medicine. It can stimulate the medicinal properties of some strange medicines. Li Chuntang used the blood of loaches to configure Tianhe San to disperse all the heat and poison and save lives."

"Although I am a Taoist, I know a little bit about the treatment methods of traditional Chinese medicine. I happen to know Li Chuntang and the prescription he invented. So Mr. Yue is also due to your sister's luck. You just found a Taoist priest and happened to be the one who prescribed the right medicine."

President Yue laughed happily and said, "Thank you for your hard work, sir, you have worked so hard."

Later, after his sister's narration, we learned the origin of the loach. A year ago, it was a not-so-large loach. It had a little white spot on its head, as if it had a meat crown, which looked so unique. The chef was about to slaughter, but his sister saw that the loach had a strange shape, so she felt compassion, so she saved it from the chef and kept it in the pond in the backyard.

But soon this kind woman forgot about the little loach, but the pond is inevitably wormy, eels are not short of food, and the thick and fertile mud layer also provides a protective layer for the loach, allowing it to spend the winter safely.

After a winter, the physique of the loach has undergone earth-shaking changes. It has become bigger and stronger, and can vaguely feel the vital signs passing by around her.

Without exception, these lives will emit a "warm current". Whenever this warm current is inhaled, the loach's cold body will feel extremely comfortable. So a small loach quietly grows into a giant among the loach under the nourishment of the human body's Yuanyang.

The pond is surrounded by shade and the south wall blocks the sunshine. This gloomy environment further encourages the evil and poison characteristics in the loach's body. It greedily absorbs the Yuanyang of all living things here, and "gives life and happiness" to itself.

Lu Shangqin said: "This is the principle of species restraint, because every life has its own characteristics. These characteristics are mutually generated and restrained, which is the way nature balances its own yin and yang. No matter you have super wisdom and ability, you cannot jump out of this boundary. So go back and get some blood for your sister to drink, and the medicine can be cured within ten days."

Amid the praises, Lu Shangqin said proudly: "I was in a good mood today. Although the story of the noble man with a face is just a legend, it is true in history and is also related to a traditional Chinese medicine doctor. This man is called Liu Quaner."

"Liu Quaner is good at making medicinal foods. Medicinal foods are actually a method of making Chinese medicinal materials. During his research on ancient medicine, he discovered a Chinese medicine formula called "Yuji Rougu Pills". This medicine was made from the hands of the medicine king Sun Simiao. Later, the imperial physician of the Tang Dynasty discovered that it was made into pills and tribute to the peerless beauty Yang Yuhuan. Yang Yuhuan took this medicine and was really bright and sweat-free. Especially after taking it, it was even more beautiful. It was a proof of Bai Juyi's famous saying "Hot spring water is smooth and the coquettish water is used to wash the cream. The waiter helped her up and was weak."

"Liu Quaner checked the formula and felt that the medicinal properties of this medicine were aphrodisiacs. Once the consequences were unpredictable in the palace, he sealed them in the cabinet. However, he did not expect that the formula was discovered by his student. This person was greedy for money, and the noble man was new to seek good luck with the emperor. The two hit it off. However, this person's medical skills were still superficial. How could he know that the medicinal materials were different in the morning and evening, and the gender of the picker would cause the medicinal properties, not to mention that the region and the Beijing era, which was a hundred years later, was different in the water and soil, and the medicinal properties were naturally very different. He used medicine according to the script, so the aphrodisiacs turned into poison. The noble man's body had a toxic attack, so there was such a strange image. It was just that ordinary people didn't know the hidden truth and thought it was a ghost."

He Ziyu and Yue didn't think it was strange. They listened with relish, but I thought it was wrong. Lu Shangqin was just a Taoist priest. It would not be surprising if he was knowledgeable to know more. The problem was that what he said seemed to have seen with his own eyes. The expression was completely about what he had experienced. The more I thought about it, the more strange I felt, and suddenly I heard a burst of laughter coming from the roof.

Looking through the sound, I saw a short and fat middle-aged man squatting on the roof. He rushed to Lu Shangqin and said, "Master Lu is so knowledgeable. His explanation is really exciting. You must be the most knowledgeable among Taoist priests."
