Yu Dayou stayed at Xiao's house for the past two days. He didn't need to be secretive anymore for two reasons.

First, because he fought for Xiao Feng in Wudang Mountain at the Dao Conference, or in the name of the chief disciple, with the spread of news, even the blind and deaf would have known about it, and it was useless to cover up his relationship with Xiao Feng.

The second is that his official certificate has already arrived, even if Yan Shifan repents, there is nothing he can do about him for the time being. What's more, there was a rumor in the palace that Yu Dayou was superior in force at the Daoist Conference, and Jiajing appreciated it very much, and said: "With such martial arts, you should go into battle to kill the enemy and make meritorious contributions." Even with this sentence, Yan Dang would not move him easily.

And Yu Dayou lived in Xiao's house, and he taught Xiao Feng's martial arts at Xiao Feng's request. Since he has obtained the official certificate, he has to take office as soon as possible, and he will not stay in Beijing for long, so if he wants to teach martial arts, he must hurry up, and living at home is the most efficient method.

The Xiao family only has a courtyard, one is two compartments and one door. Qiao Qiao slept in a wing room with Qiao Niang, and one of the wing rooms was empty. Xiao Feng asked Yu Dayou to sleep in the wing, but Yu Dayou refused to say anything, so he had to sleep in the gatehouse.

Xiao Feng said that this is not the way of hospitality, but Yu Dayou said that he is a disciple, and it is right to be a disciple to show the door to the teacher. Xiao Feng knew that he felt that the two wings were diagonally facing each other, and he was afraid that it would be inconvenient for Qiao Niang to come out and go in, so he could only follow him.

"You help me out of the siege and pretend to be a disciple, I can't help it, so don't mention any more master-apprentice gifts."

Unexpectedly, Yu Dayou was very serious: "This is a bad word, the eldest husband has said everything, and the horse is difficult to chase." I confessed to myself as a disciple in public, and you didn't deny it, so the matter is settled. Could it be that you dislike me and are not worthy of being your apprentice? ”

Xiao Feng couldn't cry or laugh, how could he still buy and sell forcibly to accept apprentices, and he still got on the bus first and then made up the ticket?

Yu Dayou said sincerely: "To be honest, I didn't have this idea before. But these days, listening to Shen Lian say a lot of things about you and what you want to do, I feel admiration from the bottom of my heart! If it weren't for that, when Lord Lu asked me to pretend to be your apprentice, I wouldn't have agreed so happily! Now that the whole world knows about it, I also ask the master to accept me, so that others will not say that I Yu Dayou is a person who deceives the world and steals fame. ”

Xiao Feng was stunned: "What? Did Lu Bing ask you to impersonate? ”

Yu Dayou nodded: "Lord Lu said, with your wit, the Qing Cultivation Sect is not worried. However, Wudang Mountain's argument is hard-hitting, not solved by machine intelligence. Among the brocade guards under him, there is no one who can beat Zhang Wuxin, and it is impossible for him to fight for you, even if it is possible, he should not be able to beat Zhang Wuxin. Come to think of it, only I am the most suitable person. ”

Xiao Feng was silent for a while: "What you just said makes sense, if I don't admit this matter, others are afraid that they will say that you see that I am getting the Sacred Heart at this time, and I insist on pretending to be an apprentice to take refuge." Yu Dayou is a dignified husband, how can he bear this reputation. That's it, tonight's wine, even if it's a formal apprenticeship, it's just wronged you. ”

Yu Dayou was overjoyed, turned over and bowed down: "There is no grievance, since ancient times, the capable person is the teacher, the teacher has the talent to help the world, Yu Dayou can worship under the teacher, it is really a lucky thing." ”

He suddenly remembered something, "From now on, I will be regarded as the second disciple of Cangjie Immortal Master, hahaha." ”

Xiao Feng is indeed the case in terms of seniority, but unfortunately Xiao Feng has not figured out the working principle of this Cangjie Heavenly Book until now, so naturally he can't teach Yu Dayou the method of measuring characters. However, Yu Dayou, a disciple, diligently teaches Xiao Feng the way of martial arts every day, which is not only inconsistent with the name of the master and apprentice, but also upside down.

For external skills, Yu Dayou thinks that Xiao Feng's physique is very good, coupled with the unique horizontal bar sandbag training method, the physical flexibility is also enough, just practice diligently. He seized the time to teach Xiao Feng his internal strength and mental method to ensure that Xiao Feng could understand, so that Xiao Feng could also cultivate by himself after he left.

Xiao Feng finally came into contact with the extremely mysterious "internal strength" since ancient times. He thought that he would encounter something incredible and beyond common sense, but when Yu Dayou explained to him the inner strength of the mind, he suddenly realized.

The internal strength method is actually an extremely subtle way to exercise the body. It's just that unlike the exercise of external strength, this kind of exercise is so subtle that it is incredible.

For example, if you want to exercise the muscles in your body, you can exercise at any time and in any order. To exercise the arms, you can use stone locks, large guns, and heavy knives; Exercising legs can be tied to sandbags, leg control, kicks, and so on.

If you want to exercise internal organs, such as cardiopulmonary function, you need to rely on running, long-distance running, sprinting, variable speed running, and so on.

But what if you want to exercise the internal organs of the spleen and stomach? Do you want to exercise your kidneys? Is there a way to exercise?

Or if you want to exercise the coordination between the arms and the pectoral muscles, and train the coordination of the force from the waist to the legs, is there a corresponding exercise method?

Internal strength is to exercise these seemingly impossible parts, and it is also the part that people are most likely to ignore.

For example, exercising the kidneys is not available anytime and anywhere, it takes the right time to adjust the person's body to a certain extent, and then it can stimulate the internal organs that are hidden deep in the body and do not usually participate in exercise with specific actions.

Another example is that a person who looks thinner will be more lethal when kicked out than a person who looks stronger. People who don't understand the principle can only be attributed to the fact that thin people have internal strength. This is true, but the essence of it is that the thin person, between the waist and legs, the invisible part of the muscles, is more developed than the person who looks strong.

This part of the invisible muscles can transmit the power of the waist to the legs like a spring, and let the power of the two muscles superimpose and explode. And this part of the muscles is not good, although it looks like the waist is thick and the legs are strong, when you really kick out, the strength of the waist and legs will not only not be superimposed, but will cancel out most of each other.

Qinggong is similar, Xiao Feng watched the basketball games of later generations, and thought why did the black stars of the NBA stay in the air for so long? The high jump is one of the reasons, but that magical ability to stay in the air is so unnatural that it simply ignores Newton's laws.

Now in Yu Dayou, Xiao Feng has seen a stronger ability to jump and stay in the air than Jordan, and he already knows all his internal skills.

To jump high depends on two things. One is muscles: leg muscles, waist-leg connecting muscles, waist muscles; The second is viscera and fat, note that it is not weight, but viscera and fat.

If body weight is made up of muscles, then it is both weight-bearing and motivation. It is important that muscles and bones are one, and the muscles of the entire human body are attached to the bones, and no matter whether they are running or jumping, they will not form a large resistance.

On the other hand, the internal organs and fat are loose and separate from the structure of the human body, creating a great resistance when running and jumping.

If you don't understand this truth, you can do an experiment, a hard-boiled egg, you rotate hard, you can turn for a long time before stopping; But a raw egg, you can't turn it twice and then stop. In the same way, if you throw an egg into the sky with the same force, the cooked egg must be higher than the raw egg.

The cultivation of external strength can make your limbs and even the whole body stronger, while the cultivation of internal strength can make your fat distribution more reasonable, and through luck, change the contraction state of the peripheral muscles of the internal organs, which can temporarily shrink the volume and become tighter.

As a result, you go from a raw egg to a boiled egg for a while, thus becoming firmer, more flexible, and more powerful. How long you can maintain this state depends on the state of your cultivation. That is, what people commonly say, how deep the internal force is.

Xiao Feng took the ingenuity and remembered what Yu Dayou said. When Yu Dayou left, they could only rely on their own cultivation slowly.

Seven days later, seeing that it could no longer be delayed, Yu Dayou had to take his official credentials and say goodbye to Xiao Feng with tears.

"Master, the things of the Japanese have come and gone, and I don't know how long I will be able to come to the capital again. If the master is free, please go to the coast and give the disciples some guidance. ”

Xiao Feng smiled and nodded, took out a letter, and handed it to Yu Dayou: "You must visit Hu Zongxian on the way back, bring this letter to him, although the two of us are famous for each other, we have never met." This letter is a greeting, and the second is to ask him to do me a favor, which is also good for him. ”

Yu Dayou didn't ask what was the matter, put away the letter and said, "Master, don't worry, your business is my business, and Brother Ruzhen will definitely do his best." ”

Xiao Feng watched Yu Dayou's horse go away, and said to himself: "Don't worry, you should have company soon." ”
