Borrow the day to change the day

Zhong Jinwei stretched his arms forward, raised his thumb, closed his left eye, looked at it for a while, then closed his right eye, and opened his left eye to look.

The people around saw Zhong Jinwei doing it in a serious manner, and they were very curious. Just by looking at it, you can know how far it is. Isn't it too mysterious?

After a while, Zhong Jinwei put down his arm, opened his right eye and said, "I already know the distance from this place to the camp."

Gonzawa has been paying attention to what method Zhong Jinwei will use to measure, but what he never expected is that Zhong Jinwei simply stretched out his hand and closed his eyes to say that he knew it.

Although Zhong Jinwei didn't look like he was joking, he didn't believe that Zhong Jinwei could measure it by stretching out his hand. [

Zhong Jinwei looked at the expression of the Portuguese captain, then looked at the suspicious eyes around him, smiled and said: "I don't believe it, come on, bring a pen and paper."

When Gu Baichuan heard this, he quickly ordered a waiter to get a pen and paper. He was also very curious about how accurate Zhong Xinghou's simple gesture would be.

While waiting for the pen and paper, Zhong Jinwei shook hands with Gonza with a smile: "You can also measure it, write the result on paper, and then ask someone to measure the real distance on the spot, and see which of us is right."

Gonza shook his head and agreed, "Okay." After speaking, he beckoned to one of his subordinates to bring over the measuring tool for measurement.

After the pen and paper were brought, Zhong Jinwei and Gonzazhao wrote down their respective values, folded them and handed them to Sun Chengzong, asking him to be the judge.

Sun Chengzong didn't open it to look, but called two guards to actually measure the distance.

Zhong Jinwei watched the two guards busy, and found that Gonza had been staring at the guard who was measuring, so he said to him: "You should also send two people to measure, so as not to be unfair."

As it was about his own salary, Gonza did not hesitate to hold it, and immediately called two subordinates to start measuring together.

In this way, a problem was discovered, and the measurement length units of the people on both sides were inconsistent.

When the question came up, Zhong Jinwei found out that his unit was different from theirs, so he made all the conversions on the spot, using the length unit of Ming Dynasty. Gonza and Zhong Jinwei had to rewrite the answers with pen and paper before handing them over to Sun Chengzong.

Li Fengjie and Wang Zunde, governors-general of Guangdong and Guangxi, were curious about how the length unit written by Zhong Jinwei was not the length unit of Ming Dynasty. This on-the-spot measurement took a lot of effort. The two of them were idle anyway during the waiting process, so they began to whisper. .

Sun Chengzong's ears were sharp, and when he heard their conversation, he had no scruples, and explained to them: "Marquis Zhongxing came back from overseas, saved the emperor, and devoted himself to Daming, so the emperor named him a marquis and worshiped the army. .His customs are different from Ming Dynasty, so there is nothing strange about it.”

After listening to Sun Chengzong's explanation, Li Fengjie and Wang Zunde understood the reason. Just when they saw Zhong Jinwei look over after hearing Sun Chengzong's words, they quickly congratulated Zhong Jinwei for his promotion.

Gonza held his hands and heard Sun Chengzong's explanation, and understood Zhong Jinwei's origin, his eyes lit up, this outsider can also be a high-ranking official in the Ming Dynasty!

Zhong Jinwei didn't pay attention to the change of Gonzawa's mentality. He chatted casually, and took this opportunity to approach Li Fengjie and Wang Zunde, and chatted with them about the situation in Guangdong and Guangxi.

At this time, there is still a big difference between Guangdong and Guangxi and later generations. In addition, Li Fengjie and Wang Zunde would not mention the issue of their jurisdiction, so Zhong Jinwei chatted for a long time, but nothing was discussed.

Sun Chengzong listened to the three people chatting with each other. He was worried about the situation of the bet, so he gave the paper in his hand to Wang Zunde, pulled Zhong Jinwei aside, and asked in a low voice: "Can you do that? Is there any basis?"

"There must be a basis, and I will only say it when I am sure." Zhong Jinwei replied with a smile.

"Tell the old man?" Sun Chengzong asked tentatively, wondering if this was Zhong Jinwei's family secret, or if it would be inconvenient to say. [

"Of course no problem." Zhong Jinwei replied while re-demonstrating and explaining to him.

"Straighten your arm forward, put your thumb up, close your left eye, and make the line of sight of the right eye align with the left side of the target along the side of the thumb, keep your head and hands still, then close your right eye, and let the line of sight of the left eye pass through the same line of the thumb. side, and remember to focus on a certain point on the ground, and then visually measure the width from the left side of the target to that point, and ten times this width is the distance from me to the target.”

Sun Chengzong listened carefully, and after Zhong Jinwei finished speaking, he tried to do what Zhong Jinwei said.

With so many years of life experience, his estimate of the length is relatively accurate.Therefore, when he said the value of ten times the estimated distance, seeing Zhong Jinwei smiling and nodding, he couldn't help being happy and said: "Is it really that simple?"

"Yeah, that's about it. This method is called eye-picking." Zhong Jinwei replied.

The eye jumping method is a simple distance measuring method commonly used in the army of later generations. Zhang Taofang, an excellent sniper of the former Volunteer Army, is best at this method.

In the Shangganling sniper battle, the Mosin Nagant rifle used by Zhang Taofang was not equipped with a scope, and the distance measurement mainly relied on visual inspection. The record of killing 210 and four enemies in three months also proved the accuracy of the skillful use of the eye jumping method for distance measurement. Spend.

Zhong Jinwei saw that the pillars were used in "Bright Sword", and found it strange at the time. After checking the information, he found out the reason, and then often bet with others to guess the distance, and won many meals for this.

"Is there any basis for this method?" Sun Chengzong remembered that Zhong Jinwei had not answered this question, so he asked again.

"Of course, the distance between the pupils of our eyes is about one-tenth of the length of our own arms. Therefore, we can obtain the distance from the place we are standing to the target by measuring ten times the width of a solid object." Zhong Jinwei explained , then turned to Gu Baichuan and said, "Lend me your knife."

Others have been paying attention to these two high-ranking court officials. Seeing that Sun Chengzong was imitating Zhong Jinwei's previous movements, they knew that Zhong Jinwei was teaching Sun Chengzong. They couldn't help being a little curious and wanted to hear what it was about.

But Sun Chengzong pulled Zhong Jinwei aside to ask questions before, obviously he didn't want them to know what he said.Therefore, they dare not approach.

Gu Baichuan had been looking at Zhong Jinwei's side all the time. Now when he heard that he was going to use a knife, he hurried over, pulled out the knife, turned his wrist, and handed the knife to Zhong Jinwei with the handle facing Zhong Jinwei.

After Zhong Jinwei got the knife, he scratched it on the dry mud floor with the tip of the knife, and explained to Sun Chengzong: "This side is ten times different from this side. This is a right angle, and this is also a right angle."

Sun Chengzong couldn't understand what he was listening to. He didn't understand why this side is ten times, here is a right angle, and that side is ten times.He watched Zhong Jinwei explaining seriously. Although he didn't understand, he didn't need to guess and knew that what Zhong Jinwei said must have a set of basis, and there was no mistake.

After Zhong Jinwei finished speaking, Sun Chengzong shook his head and sighed: "I'm really old, I don't understand this." Then he found that Gu Baichuan was standing next to him and didn't avoid it, so he asked him, "Do you understand?"

Gu Baichuan was also confused when he heard it, he shook his head and said, "This subordinate doesn't understand either."

Zhong Jinwei returned the knife to Gu Baichuan, clapped his hands and said, "It's nothing difficult, it's just a little knowledge of mathematics and geometry."

"But the geometry that Xu Shangshu said?" Sun Chengzong knew that Xu Guangqi called shape science geometry, so he asked when he heard Zhong Jinwei's words.

Zhong Jinwei nodded: "Exactly, there is a lot of mathematical knowledge that can be used in military affairs, not just geometry."

Gu Baichuan listened to it, and thought to himself that he should learn this mathematics carefully when he has time, and it will always be useful in the future.

When Sun Chengzong was about to express his feelings, the guards who measured the distance came back. He was eager to know the final answer, so he took the lead and walked back to the crowd. [

The guard reported the actual length measured to Sun Chengzong.The two subordinates of Gonzawa also said the length, and the interpreter on one side translated it to Sun Chengzong, so as not to make a wrong translation on purpose by Gonzawa.

The difference in length measured on both sides is very small, and this error is understandable.Everyone's eyes focused on the two pieces of paper in Wang Zunde's hand.

Sun Chengzong signaled Li Fengjie and Wang Zunde, who were standing aside, to each take a piece of paper and read it out to the public.

Gonza was very nervous. He didn't believe that Zhong Jinwei's result would be accurate, but when he saw that Zhong Jinwei was teaching Sun Chengzong again, he felt a little uneasy.

As soon as the answer was released, it was found that Zhong Jinwei's answer was similar to the length measured by Gonza's subordinates, and Gonza's answer was similar to the length measured by Sun Chengzong's personal guard.

That is to say, the results of Zhong Jinwei and Gonzasha are very close, almost the same, and it is impossible to tell which one is more accurate.

Gonza did not expect that this young high-ranking official of the Ming Dynasty could measure the distance, and he could measure it without any tools.

He was very unwilling, after all, it was about their salaries.So, he said: "I can only measure the distance, but can't explain the shooting. I don't accept it."
