At noon, after having dinner with Zhang Shiqian, Zuo Houde and the others rested in the tent.

Zuo Houde didn't go to the shooting range again, and his arm still needed to be recovered, but Zuo Houde still understood this reason.

In the tent, there are a few old military doctors who are still taking a lunch break, and it is inconvenient to chat, and there is nothing to do, Zuo Houde opened a medical book "Materia Medica" collected by Dr. Zhang Shiqian, which can be traced back to the period of the Three Emperors and Five Emperors. Of course, there are many versions that have been circulated to this day, and Dr. Zhang said that his book is a common version on the market, and there are many ancient medical techniques in it.

The doctors in this barracks are also well-connected, and most of the people who study medicine are good people. Most doctors also have no disputes over interests, and there are exceptions to the saying that peers are enemies, after all, the real interests are still between pharmacies.

Most of the people like Zuo Houde are just sitting in these pharmacies and borrowing the signboards of the pharmacies, and these doctors don't have their own pharmacies, after all, the capital required to open a pharmacy is not something that ordinary people can have, and they have to be responsible for the negative problems of opening a pharmacy, and it is much simpler to be a doctor.

So when I entered the barracks, the doctors had a very good relationship with each other. For example, Zhang Shiqian is willing to show his collection of medical books to Zuo Houde.

Looking at it, Zuo Houde suddenly remembered a story "Ji Chang Learns to Shoot",

It is said that the Ganfly was a man who was good at archery in ancient times, and when he pulled the bow, the beast fell, and the bird fell. One of Sugarfly's disciples was named Feiwei, who learned archery from Sugarfly, but his archery skills surpassed that of his master. Ji Chang learned archery from Feiwei again. Feiwei said, "You first learn to look at things without blinking, and then you can learn to shoot arrows." ”

Ji Chang returned home, lay on his back under his wife's loom, and practiced not blinking with his eyes on the shuttle on the loom. Two years later, he didn't blink even though the awl spike was on his eyelids.

Ji Chang told Feiwei about his practice, and Feiwei said: "It's not enough, you have to learn to see things." Practice to see small objects as clearly as big things, and small things as easy as significant objects, and then come back to me. ”

Ji Chang tied a lice with the hair of the yak's tail and hung it on the window, facing south and looking at it from a distance, and after ten days, the lice gradually grew bigger in Ji Chang's eyes.

Three years later, lice were the size of a wheel in his eyes. Everything else you look at in this way, it's as big as a hill. Ji Chang used a bow reinforced by the horns of Yandi, and used the canopy stalks produced in the north as arrows, and shot the lice hanging from the window, penetrating the center of the louse, but the hair was not broken.

Ji Chang told Feiwei about his practice again, and Feiwei was so happy that he raised his footsteps, stomped his feet, and patted his chest. "You've got the hang of archery!" After Ji Chang learned all the kung fu of Feiwei, he felt that only Feiwei could match him in the whole world, so he planned to get rid of Feiwei.

Finally, one day the two met in the wild. Ji Chang and Feiwei both shot arrows at each other, and the arrows shot by the two people collided in the air, and they all fell to the ground, but no dust was raised. In the end, Feiwei's arrow was finished, and Ji Chang had the last one left, he shot it, and Feiwei hurriedly raised the thorns beside him to poke the flying arrow, blocking the arrow exactly as it was.

So both of them threw their bows and hugged each other and wept, believing each other father and son, and vowed not to pass on this technique to anyone again.

From this story, Zuo Houde extracted a key message, to practice shooting and first practice eyesight. He decided to follow Ji Chang's method.

The first step is to see things without blinking, and the second step is to see small objects as clearly as seeing big things.

Thinking of it, Zuo Houde continued to look at the medical book, unlike before, Zuo Houde's eyes did not blink, and when Zuo Houde finished reading the medical book, the two eyes unconsciously shed tears. Zuo Houde can only gently wipe his eyes with a hot towel.

In order to make it as easy as a conspicuous object to see a small object, Zuo Houde marked the green leaves of a green plant 10 meters away, eliminating distractions, concentrating, and concentrating on the gaze, and identifying the lines on the green leaves.

One afternoon, Zuo Houde was trying out the method of eye training that he had summed up, first of all, he did not blink an eye when he read medical books, and when he was tired, he looked into the distance, stared at the green leaves, and observed its lines.

One afternoon, Zuo Houde's eyes were red and swollen. Dr. Zhang Shiqian still thinks that Zuo Houde misses his family?

Zuo Houde told him about the matter, which made him cry and laugh, "Your method, I don't know if it has any effect, my master is old, his eyes are still bright, he has a set of methods to protect his eyes, do you want to know?" Zhang Shiqian said.

Zuo Houde's eyes lit up when he heard this, "Brother Zhang, just tell me, and sell Guanzi!" ”

"Then next time, when you go home to visit relatives, remember to bring me your pre-Qin "Three Elimination Theory" to me." Zhang Shiqian said.

This "Three Elimination Theory" is a treasure, Zuo Houde finally got it out of the pawn shop, and he didn't show off with Zhang Shiqian, and people who study medicine love to compare these.

"Okay, I'll bring it to you next time I visit my family!" When Zuo Houde heard this, he immediately agreed, after all, he is not a stingy person.

"Okay, then I'll tell you that when my master washes his face every morning, he first soaks a towel, compresses his eyes and temples, and about a stick of incense, which has been insisted on for decades, and his eyesight is still good!"

When Zuo Houde heard it, although he thought it was simple, there were successful cases, so he decided to give it a try.

"Then I'll thank Brother Zhang," Zuo Houde laughed after speaking.

Zhang Shiqian smiled: "Don't forget my "Three Elimination Theory". ”

Next, Zuo Houde continued to try the method he was groping, changed to a medical book, and continued to read without blinking.

Time flies, a month passed in a blink of an eye, during which Zuo Houde and others went home to visit relatives once, and after reporting safety to their parents, they warmed up with their wives for a while, and Zuo Houde left.

This time, Zuo Houde brought an extra bookcase, which was full of books, mostly medical books, and of course, other miscellaneous books.

The last time he stayed in the barracks and found out a set of methods for practicing his eyes, Zuo Houde read an average of one or two medical books every day, and this time he brought more.

That set of eye training methods is useful, at present, the branches and leaves on the tree five steps away from Zuo Houde, Zuo Houde can see its lines clearly.

Of course, practicing 100 arrows a day, Zuo Houde is also insisting, and now, with an arrow target fifty steps away, Zuo Houde has been able to hit the bull's-eye like Li Er did at the beginning.

Even the skill of archery has appeared, Zuo Houde's system layout. It can be seen that it has already entered the house. But Zuo Houde is still practicing.

Fifty paces can shoot at the target, and there are eighty paces and a hundred paces. Even on the battlefield, there is no fixed target, it is all moving.
