Otaku Engineer in Great Tang Dynasty Chapter 2155: The truth is revealed! (middle)

"That's right! The Huansheng Powder that can bring dead fish back to life is indeed made by the poor monk according to the academy's "Chemistry Textbook!"

In the room, Gae nodded. Seeing that the teachers and students were still puzzled, he continued: "You may still not understand Huanshengsan. After all, this is just a name given by the poor monk himself, but If you talk about its other name, everyone will understand that this Huansheng San is actually sodium peroxide!"

"Sodium peroxide?"

Everyone couldn't help exclaiming, because they were so familiar with the name, Zeng Ziran murmured at this moment: "According to the textbook, sodium peroxide reacts with water to generate a large amount of oxygen. Is it because There is a lot of oxygen in the water, so the black fish that was dying instantly became alive and kicking, making people mistakenly think that it was resurrected?"

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

"This little benefactor is right!"

Gaer glanced at Zeng Ziran, nodded approvingly, and said:

"The black fish used by the poor monk to perform the dead fish resurrection technique in the evening has been out of the water for half an hour before that. Everyone should know that the fish can only separate the oxygen in the water with its gills, but It cannot separate the oxygen in the air, so if it is placed in the air for a long time, the fish will suffocate to death!

The black fish had been stranded for half an hour, and it was already dying. However, the fish tank that the poor monk used to hold the fish later contained stagnant water with little oxygen, so even if the black fish entered the water, it was still very weak. Difficult to take in oxygen, in the eyes of outsiders, it is almost a dying fish!

If you have studied chemistry, you should know that 2na2o2+2h2o=4naoh+o2, so when the poor monk pours a small amount of Huansheng powder, that is, sodium peroxide into the fish tank, the sodium peroxide reacts with water, and the short-term A large amount of oxygen will be produced in the water within a short period of time, and the snakehead, which is already hypoxic, suddenly gets so much oxygen, it will naturally become alive and kicking! This is the resurrection of dead fish in the eyes of the common people! "

After listening to Gae's detailed explanation, everyone couldn't help being amazed. Li Tai frowned and asked: "Sodium peroxide reacts with water, although oxygen will be produced, but sodium hydroxide will also be produced in water at the same time. This substance is highly alkaline, wouldn't the fish die if they stayed in the strong alkaline solution for a long time?"

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

Gaer smiled and said: "Your Highness, that 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 formed in the water, the other The concentration will not be very high. The water in the whole fish tank is at most weakly alkaline. This kind of water quality will not cause much impact on the tenacious black fish. Don't forget some salt, Your Highness There are also a lot of fish growing in the alkali lake, that is to say, for some fish, the alkaline liquid environment will not affect their survival;

Secondly, due to the urgent time, the poor monk had never experimented with black fish before, and he was somewhat uncertain, so in the evening, not long after showing the resurrection technique of dead fish to the people, The poor monk asked people to remove the fish tank, because he was worried that the black fish would die slowly due to the alkaline solution environment! His Highness should have noticed this detail through the window of the inn room at that time!

However, it turned out afterwards that the poor monk's worries were unnecessary, because until all the people in Jian'an Square received the Huansheng incense, the black fish in the fish tank was still as lively as before! "

Li Tai was amazed when he heard the words, he really did not expect that Gae had such a thorough grasp of the knowledge in the academy's "Chemistry Textbook", but how long has he only been in Yunshan?

Mo Chui frowned, and said, "The purpose of Master Jiaer's demonstration of the resurrection technique of dead fish is to attract the people to frantically seek the fragrance of rejuvenation? Shengxiang has a rejuvenating effect similar to that of Huanshengsan, 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 this question because Gae saved Li Tai after all. The common people, after using the Huansheng incense, found that the pain has not been alleviated at all. How disappointed will those common people be? As soon as he thought of this, he couldn't help but want to seek "justice" from Gae for those people.

"Mr. Mo Chui..."

Li Tai opened his mouth, wanting to say a few words for Gae, but Gae recited a Buddha's name:

"Amitabha!"

Then said solemnly: "The monks really don't lie, the poor monk has broken the precept this time! After returning to Chang'an, the poor monk will retreat and worship the Buddha for a month, and ask the Buddha for sin! But...Huanshengxiang is not It has the effect of rejuvenation, but for ordinary people, it will not do any harm, because the fragrance of rejuvenation does have the effect of calming the mind!

And sometimes, giving the patient comfort can relieve or alleviate the patient's condition to a certain extent! The common people believe that Huanshengxiang has the effect of rejuvenating vitality and healing old injuries. With this kind of psychological comfort and psychological suggestion, even if Huanshengxiang has no such effect, their condition will be improved to a certain extent! "

If Li Zexuan was present, he would definitely agree with Gae's point of view, because what Gae said has a certain scientific basis. In modern medicine, there is something called "placebo". The phenomenon mentioned by Gae is called the "placebo effect" in modern medicine!

Placebos are tablets, pills, or injections that have no therapeutic effect. It has a substitute and comfort effect on people who have taken a certain drug for a long time and caused adverse consequences. The placebo itself has no therapeutic effect, but it plays an analgesic, analgesic or symptom-relieving role because of the patient's trust in the doctor, the patient's self-suggestion, and the expectation of the efficacy of a certain drug. In the experimental research of clinical medicine, in order to observe the curative effect of a certain drug, it is also often used in controlled trials.

Modern medical research shows that the short-term effect of placebo on gastroduodenal ulcer can reach up to about 70% when treated by a doctor who is highly trusted by the patient. For patients with malignant tumors, the placebo will have a "placebo effect" on relieving some symptoms, but it will not cause death or delay life!

I have to say that Gae is indeed a talent. Not only is he extremely talented in chemistry, but also he has found a new way in controlling people's hearts and treating diseases. Li Erruo really killed him back then. Yes, that's really a pity!

"There is still such a saying? But how is it possible?"

Mo Chui raised his eyebrows in surprise, a little in disbelief.

He had never heard of this kind of treatment method. If Gae hadn't saved Li Tai first, he would have thought Gae was a swindler!

"Amitabha! This matter is absolutely true, and the poor monk dare not lie! Previously, the poor monk was in the sky...in the treatment of people, he witnessed many similar examples with his own eyes. It is absolutely not a lie!"

Gae folded his hands together, recited the Buddha's name, and explained to Mo Chui solemnly.

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

Li Tai knew Gae's true identity, and he no longer had any doubts when he heard this, so he chimed in and said:

"Master Jiaer has treated many people before, and I believe in what Master Jiaer said! Moreover, I have also used this Huansheng Incense. It really has the effect of calming the mind, helping sleep and calming the mind. It is absolutely harmless to ordinary people! Besides, the Huansheng incense distributed by Master Jiaer to the people is free, and the people have never paid for it, and it is not a deception. Humanly speaking, it's not even a lie!

Because according to the government's investigation, many people who received Huanshengxiang in Jian'anfang sold Huanshengxiang to some dignitaries, rich and powerful businessmen in the city. Incense is hard to find! For those ordinary people, instead of losing anything because of Master Gae’s white lies~IndoMTL.com~, they got a lot of wealth. With this money, they can go to the city to find better The doctor is cured! "

Hearing this, everyone nodded secretly, looking at Gae with more respect.

Mo Chui also wanted to understand the key point, he bowed his hands to Gae apologetically, and said: "Mo is so stupid that he misunderstood the master's painstaking efforts, he was reckless for a while, and I hope Master Gae will forgive him! "

Ga'er smiled as if nothing had happened, and said: "Amitabha! Donor Mo's heart is for the common people and the common people, what's wrong with that?"

The disciples of the Mohist school have taken saving the common people as their duty for generations. Gae's summary is indeed just right!

After Mo Chui heard this, he was even more ashamed and said: "Mr. Mo blamed the master without knowing the cause of the matter. The master does not blame him. Mo is already grateful and cannot afford such a praise from the master!"

Ga'er smiled and did not continue to entangle in this matter. He continued to explain: "At that time, the poor monk used Huansheng powder to attract Huansheng incense, so that the people frantically begged for incense, just to create a crazy scene. , so that the Turkic spies in the inn thought that the poor monk was a magic stick, and this puja was just an ordinary puja, which made them relax their vigilance towards the puja!

At the same time, this is also an opportunity for His Highness to introduce incense into the room! The poor monk believed that with the wisdom of His Highness, he would definitely be able to see that the Huansheng incense was the key to breaking the situation, so he would try every means to get the Turkic spies to get two Huansheng incense! "

Everyone was stunned again, and couldn't help but applaud Gae's ingenious calculation in their hearts.

At this time, Tie Dan couldn't help wondering: "But Master Gae, if Qingque didn't understand what you mean, and didn't see that Huanshengxiang is the key to breaking the game, what should I do?"
