I have become immortal, Taoist friends still need to be diligent

"Centurion, your letter."

A city at the junction of the Western Wei Dynasty and the Song Dynasty, outside Zhangcheng.

In a military camp, Zhang Fugui, who was returning to his tent after listening to the commander's arrangements, saw a commander coming over with a heavy envelope.

"Okay, give it to me, you go and do your work first."

After waving to signal the chief to retreat, Zhang Fugui walked into the tent. At this time, he was already a centurion and had his own small tent.

"Who are they, my parents? It's true to write such a thick letter."

Looking at the bulge on the back of the letter, Zhang Fugui guessed with a smile.

"Stab~"

After tearing open the envelope and placing it on the cot, I saw a few words.

"Junior brother Zhang Fugui...Li Mu of Fenglin Martial Arts School in Xiaohe Village, Huangyuan Town, Qingping County, courtesy name Muzhi..."

"Oh, it's a letter from senior brother."

Zhang Fugui was surprised. He had not contacted anyone at the martial arts school since he joined the army, and he rarely contacted his family.

Because the station address cannot be told to others, the addresses he gave to his family were fake addresses that were changed by the military camp every month.

He never thought that Li Mu could contact him.

"a book?"

Looking at the book in his hand, Zhang Fugui was confused.

""Wu Jing": Qingping Li Mu is called Muzhi?"

Li Mu really went to great lengths to make his acquaintances remember his name and characters.

"Eldest Brother is so funny. Although Eldest Brother has a good understanding, who can understand things on the battlefield without coming here? I have been here for so long and I dare not say that I understand."

Zhang Fugui was not optimistic about Li Mu's military strategy, so he smiled, but still opened the book. After all, he hadn't talked to his cheerful and easy-going senior brother for a long time, and it was quite interesting to read his childish guesses.

As soon as he saw Zhang Fugui, his whole mind went into the book, forgetting the passage of time outside. .

"Centurion, it's time to eat."

With the voice of a soldier, Zhang Fugui was finally pulled out of the book.

"It's almost dark? This book is truly a divine book, and Senior Brother is truly a divine being."

There are not many words in the book, but Zhang Fugui fell in love with it at a glance. I read it over and over again and enjoyed it with gusto.

"Okay, come in, put the food here, and then go back. Remember, don't come here if you have nothing to do. I'll ask you to come again."

Zhang Fugui said calmly to the soldiers outside the tent.

"Yes."

Zhang Fugui felt a little unhappy when he was interrupted by the soldiers, but in order to continue studying well later, he told the soldiers to prevent them from cleaning up the dishes again later.

Then Zhang Fugui lit the oil lamp in advance and fell into hard study again.

……

"Brother Li, you are finally back. The businessman has been pressing you so hard these days that I am embarrassed to refuse. If you don't come back, I will go to your house to find you."

On the second day after Li Mu arrived in Qingping County, Liu He knocked on the door and shouted. As soon as the two sat in the private room, Liu He complained.

"Oh, is it so popular?"

Li Mu asked curiously. After all, he had only been away for ten days, and he had three spare ones before.

"That's right. The businessman said that there is a wealthy family in the next state city who wants twenty pieces. He is pressing for them. We can negotiate the price later."

Liu He replied.

"Oh, this businessman is not simple. His business has reached the state capital."

Li Mu sighed.

"That's right, this relationship was introduced by a previous businessman. He said he was an elder in his family and was very powerful in the three northwest states."

Liu He said proudly, as if he was the businessman.

"Oh, then help me ask if I can get the Yi Jing shape-changing technique. If so, I can increase production."

Li Mu was interested as soon as he heard about it. Generally, only low-grade exercises are available in the market. Middle-grade and higher-grade exercises are particularly rare and hard to come by.

Generally, they are autobiographies of apprenticeships, families, and sects.

"Okay, I'll write a letter when I get back."

Liu He didn't ask Li Mu what he wanted this kind of technique for. People in the world would inevitably have this need when they go out.

After all, we often have to "act chivalrously and do justice."

……

Later, Li Mu increased the time for blacksmithing, and planned it according to the standard of fifteen strokes a month.

A few years passed in the blink of an eye, and Li Mu was already twenty-six years old.

"Brother Li, this time the businessman came in person and said that this exercise can definitely meet your requirements."

Li Mu was pulled out of the medical clinic by Liu He. In the past few years, the businessman had written letters about the effects of seven or eight exercises, but the results were not what Li Mu expected.

Li Mu felt that there was no chance, but as soon as he went to the medical clinic today, Liu He came with several helpers.

"Brother Li, let me introduce you. This is Senior Tao Wutao of the Tao family."

"Senior Tao, this is my brother Li Mu, also known as Muzhi."

"I have admired Senior Tao's reputation for a long time, and today I saw that he is truly worthy of his reputation."

Li Mu looked at the slightly thin but piercing middle-aged man in front of him and said.

"Well, Li Xiaoyou is also very heroic. Tao's trip is well worth it."

After exchanging business compliments, the three of them waved and exited the entourage.

"Senior Tao, don't you know that technique?"

Li Mu asked a little eagerly.

After all, he hasn't changed his appearance in three years, and he is 100% sure that he has been forgotten by time. In order to prevent others from seeing him, he is ready to use simple disguise techniques.

"Haha, since Li Xiaoyou is quick to talk, I won't do the ink. Here you go."

Tao Wu saw that Li Mu was really anxious, so he took out a book from his arms.

""Marrow Cleansing and Blood Exchange Technique"?"

Li Mu looked at the exercises in front of him and slowly opened the book. Tao Wu and Liu He didn't bother either.

Li Mu read the entire technique at a glance and finally understood the main effects of this technique.

This skill is a high-grade skill, but he does not cultivate internal strength, only the bone marrow. Practicing for three months can improve his qualifications a little, and control the hematopoietic function of the bone marrow to change his complexion.

A year of practice can improve your qualifications by one percent and control your complexion more smoothly.

Five years of practice can increase your qualifications by 10%, and you can control skin firmness, black and white hair, and bone gaps.

Ten years of practice will increase your qualifications by 20%, and control the turbidity of your eyes.

Qualifications improved by 50% in twenty years...

Qualifications improved by 10% in thirty years...

……

Li Mu closed the exercise and suppressed the excitement in his heart.

"Senior Tao, I like this technique very much. What are my requirements?"

Li Mu never thought about lowering the price. First maliciously suppress the value of the other party's things, and then get them at a low price.

That's not something a smart person does. After all, the person opposite is a well-informed person, so it's better to be sincere.

"Well, it's fine if you like it, little friend Li. This exercise is a bit useless, but it does have its own unique features."

Isn't it? For ordinary people, it is too useless. After all, the time to increase qualifications is too slow, and there will be almost no people waiting to develop their qualifications.

"But it is a top-grade technique after all. I just ask Little Friend Li to sell me the method of making Xiuchun Dao. What do you think, little Friend?"

Tao Wu smiled and said to Li Mu.

He had mentioned it to Li Mu many times before, but Li Mu never gave a definite answer.

"Senior Tao is joking. Xiuchundao is a secret that has not been passed down from my family's ancestors. How dare I pass it on to outsiders at will?"

Li Mupi said with a smile.
