"That's right! The Huansheng Powder that can revive dead fish was indeed made by a poor monk based on the "Chemistry" textbook in the academy!"

In the room, Gae nodded. Seeing that all the teachers and students were still confused, he continued: "You may still not understand when it comes to Huanshengsan. After all, this is just a name given by the poor monk himself, but if it comes to Its other name, I believe you can understand, this Huansheng Powder is actually sodium peroxide!"

"Sodium peroxide?"

Everyone couldn't help but exclaimed, because this name was so familiar to them. Zeng Ziran murmured at this time: "According to the textbook, sodium peroxide reacts with water to generate a large amount of oxygen. Is it because there is too much oxygen in the water?" There is a lot of oxygen, so the dying black fish suddenly becomes alive and kicking, making people mistakenly think that it has come back to life?"

The teachers and students of the academy who were able to participate in the construction of the telegraph relay station were all with solid engineering skills. After Zeng Ziran said this, everyone looked stunned and turned their attention to Gae.

"This little donor is right!"

Jia'e glanced at Zeng Ziran, nodded approvingly, and said:

"The black fish used by the poor monk to perform the art of resurrecting dead fish in the evening had been taken out of the water for half an hour before that. Everyone should know that only when a fish is in the water can it use its gills to separate the oxygen in the water, but it cannot It separates the oxygen in the air, so if it is left in the air for a long time, the fish will suffocate to death!

The snakehead fish had been stranded for half an hour and was already dying. The water in the fish tank that the poor monk later used to hold the fish was stagnant water with little oxygen, so even if the snakehead fish entered the water, it would still be difficult to absorb it. Oxygen, in the eyes of outsiders, is almost like a dying fish!

If you have studied chemistry, you should all know that 2 Na2O2 + 2 H2O = 4 NaOH + O2↑, so when the monk poured a small amount of Huansheng Powder, that is, sodium peroxide into the fish tank, the sodium peroxide reacted with the water, A large amount of oxygen will be produced in the water in a short period of time. The snakehead fish, which is already lacking oxygen, suddenly gets so much oxygen, and it will naturally become lively! This is what people think of as the art of resurrecting dead fish~! "

After listening to Gae's detailed explanation, everyone couldn't help but marvel. Li Tai frowned and asked: "Sodium peroxide reacts with water. Although it will generate oxygen, it will also generate sodium hydroxide in the water. This substance has It’s highly alkaline. If a fish stays in a strongly alkaline solution for a long time, won’t it die?”

Most of the students nodded secretly, obviously agreeing with Li Tai's question.

Gae smiled and said: "Your Highness, this is a good question! However, first of all, the amount of sodium peroxide that the poor monk put into the fish tank was relatively small. Even if sodium hydroxide was generated in the water, its concentration would not be It will be very high. The water in the entire fish tank is only in a weakly alkaline state at most. Such water quality will not have much impact on the tenacious snakeheaded fish. Your Highness, don’t forget that some salt-alkali lakes , there are also many fish growing there, that is to say, for some fish, the alkaline liquid environment will not affect their survival;

Secondly, due to time constraints, the poor monk had not actually done any experiments with black fish before, and he was somewhat unsure. Therefore, in the evening, not long after showing the people the technique of resurrecting dead fish, the poor monk People removed the fish tank because they were worried that the snakehead fish would slowly die due to the alkaline solution environment! His Highness must have noticed this detail through the window of the inn room!

However, it later proved that the poor monk's worries were unnecessary, because even after all the people in Jian'an Square received the Huansheng Incense, the black fish in the fish tank was still as lively as before! "

When Li Tai heard this, he was amazed in his heart. He really didn't expect that Gae had such a thorough grasp of the knowledge in the academy's "Chemistry" textbook. But how long had he been in Yunshan

Mo Chui frowned and said: "Master Jia'e showed the technique of resurrecting dead fish. The purpose is to attract people to crazily ask for the rejuvenating incense? What's the point of doing this? And before, Master Jia'e said that the rejuvenating incense has It has a rejuvenating effect similar to that of Huansheng Powder, but the actual situation is not like this at all. Isn’t this deceiving the people?”

Mo Chui's last question was a bit sharp. In fact, he didn't want to ask it, because Jia'e saved Li Tai after all, but those people who originally wanted to ask for Huanshengxiang to go home to treat themselves or their relatives, in After using Huanshengxiang, they found that the pain was not relieved at all. How disappointed would those people be? When he thought of this, he couldn't help but want to seek "justice" from Gae on behalf of those people.

"Mr. Mo Chui..."

Li Tai opened his mouth and wanted to say a few words for Kae, but Kae recited a Buddha's name:

"Amitabha~!"

Then he said with a solemn face: "Monks really don't tell lies. This poor monk broke the precepts this time! After returning to Chang'an, the poor monk will retreat to pray to the Buddha for a month and apologize to the Buddha! However... although the rejuvenating incense has no rejuvenating effect , but for ordinary people, there will be no harm, because Huanshengxiang does have the effect of calming the energy and concentrating the mind!

And sometimes, giving the patient a sense of comfort can alleviate or alleviate the patient's condition to a certain extent! People believe that Huanshengxiang has the effect of rejuvenating and healing old wounds. Under this kind of inner comfort and psychological suggestion, even if Huanshengxiang does not have this effect, their condition will be improved to a certain extent! "

If Li Zexuan were at the scene, he would definitely agree with Kae's views, because what Kae said has a certain scientific basis. In modern medicine, there is something called "placebo", and what Kae said This phenomenon is called the "placebo effect" in modern medicine!

Placebo refers to tablets, pills, and injections that have no therapeutic effect. It has a substitution and comforting effect on people who have suffered adverse consequences from taking certain medications for a long time. Placebo itself does not have any therapeutic effect, but it plays an analgesic, analgesic or symptom-relieving role due to the patient's trust in the doctor, the patient's self-suggestion and the patient's expectation of the efficacy of a certain drug. In experimental research in clinical medicine. In order to observe the efficacy of a certain drug, it is also often used in controlled trials.

Modern medical research shows that when treated by a physician who is highly trusted by patients, the short-term efficacy of placebo in treating gastroduodenal ulcers can reach up to about 70%. For patients with malignant tumors, placebos can produce a "placebo effect" in relieving certain symptoms, but are ineffective in causing death or injury or delaying life!

It has to be said that Gae is indeed a talent. Not only is he extremely talented in chemistry, but he also has a new approach and his own style in controlling people's hearts and treating diseases. If Li Er had really killed him, then What a pity!

"Is there such a thing? But how is it possible~?"

Mo Chui raised his eyebrows in surprise and said in disbelief.

He had never heard of this kind of treatment method. If it weren't for the fact that Gae saved Li Tai first, he would have thought that Gae was a liar!

"Amitabha! This matter is absolutely true. The poor monk dare not lie! Previously, when the poor monk was in heaven... he witnessed many similar cases with his own eyes while treating people. It is definitely not a lie!"

Kae clasped his hands together, chanted the Buddha's name, and explained to Mo Chui seriously.

He wanted to say that he had witnessed countless such examples in the process of treating illnesses in Tianlong Sect, but when the words came to his lips, he thought of his sensitive identity and quickly changed his words.

Li Tai knew Gae's true identity. After hearing this, he no longer had any doubts and spoke to help:

"Master Kae has treated many people before. I believe in Master Kae's words! Moreover, I have also used this Huanshengxiang. It does have the effect of calming the mind, promoting sleep, and calming the mind. It proves that this thing is useful for ordinary people. It's absolutely harmless! Besides, the Huansheng incense distributed by Master Gae to the people is free. The people have never paid for it, and it can't be said to be deceiving. At most, it is a white lie, and for some people , not even a lie!

Because according to the government's investigation, many people who received Huanshengxiang in Jian'anfang sold Huanshengxiang to some dignitaries and wealthy businessmen in the city. Even so, Huanshengxiang is still hard to find in Taiyuan City. ! For those ordinary people, instead of losing anything because of Master Gae's white lies, they actually gained a small amount of wealth. With this money, they can go to the city to find better doctors for treatment. ! "

Hearing this, everyone nodded secretly and looked at Gae with a little more respect.

Mo Chui also figured out the key. He bowed his hand to Jia'e with an apologetic look and said, "Mo is so stupid that he misunderstood the master's painstaking efforts. He was reckless for a while, and I hope that master Jia'e will understand~!"

Jia'e smiled nonchalantly and said, "Amitabha! Almsgiver Mo cares about the people and cares about the common people. What's wrong with that?"

Mohist disciples have taken it as their duty to save the common people from generation to generation. Jia'e's summary is indeed just right!

After Mo Chui heard this, he felt even more ashamed and said: "Mo didn't understand the cause of the matter, so he accused the master. If the master doesn't blame, Mo is already grateful and cannot deserve such praise from the master!"

Gae smiled and did not continue to struggle with this matter. He continued to explain: "The poor monk used Huansheng powder to induce Huansheng incense and made the people crazily ask for the incense, just to create a crazy scene and make the inn The Turkic spies inside thought that the poor monk was a magician and that this dharma conference was just an ordinary dharma conference, which made them relax their vigilance towards the dharma conference!

At the same time, this is also an opportunity for His Highness to introduce incense into the house! The poor monk believes that with His Highness's wisdom, he will definitely be able to see that this Huansheng Incense is the key to breaking the situation, so he will try his best to get the Turkic spies to get two Huansheng Incense! "

Everyone was suddenly enlightened again, and couldn't help but admire Gae's ingenious plan in their hearts.

Tiedan couldn't help but wonder at this moment: "But Master Gae, what if Qingque doesn't understand your meaning and doesn't see that Huanshengxiang is the key to breaking the situation?"
