Zhong Jinwei stretched his arm forward, raised his thumb, closed his left eye, and looked for a while, then closed his right eye and opened his left eye to look.
People around him were very curious when they saw Zhong Jinwei doing it seriously. Isn't it too mysterious to know how far away he is just by looking at it?
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."
Gonsar was always paying attention to what method Zhong Jinwei was going to use to measure, but what he never expected was that Zhong Jinwei simply stretched out his hand and closed his eyes and said he knew.
Although Zhong Jinwei didn't look like he was joking, he didn't believe Zhong Jinwei could detect it by stretching out his hand like that.[
Zhong Jinwei looked at the Portuguese captain's expression, then looked at the suspicious eyes around him, smiled and said, "You don't believe it, do you? Come on, bring me a pen and paper."
When Gu Baichuan heard this, he quickly ordered a servant to get paper and pen. He was also curious about how accurate Zhongxing Hou could be with such a simple gesture.
While waiting for paper and pen, Zhong Jinwei smiled and said to Gonsa: "You can also measure it, write the result on paper, and then have someone measure the real distance in person to see which of us is more accurate."
Gonzago nodded in agreement and said, "Okay." After saying that, he waved to one of his subordinates to bring over the measuring tools for measurement.
After bringing the paper and pen, Zhong Jinwei and Gongsahou wrote down their respective values, folded them and handed them to Sun Chengzong, asking him to be the judge.
Sun Chengzong did not open it to take a look, but called two personal guards to actually measure the distance.
Zhong Jinwei watched the two guards busy, and found that Gongsahao had been staring at the measuring guards, so he said to him: "You should also send two people to measure, so as not to be unfair."
When it came to his salary, Gonza didn't hesitate and immediately called two of his subordinates to start measuring it together.
In this way, a problem was discovered. The measurement units of length of the people on both sides were inconsistent.
When Zhong Jinwei heard the question, he found that his unit was also different from theirs, so he did all the conversions on the spot, using the length units of the Ming Dynasty. Gongsa Wai and Zhong Jinwei respectively asked to rewrite the answers with pen and paper before giving them to Sun Chengzong.
Li Fengjie and Wang Zunde, the governors of Guangdong and Guangxi, were very curious that the length units written by Zhong Jinwei were not the length units of the Ming Dynasty. This field measurement took a lot of effort. While they were waiting, they were idle anyway, so they started whispering.
.
Sun Chengzong's sharp ears heard their conversation, and he did not hesitate and explained to them: "Zhongxing Hou returned from overseas, saved the emperor, and devoted himself to the Ming Dynasty, so the emperor granted him the title of Marquis and Supervisor of the Army.
.His customs are different from those of the Ming Dynasty, so there is nothing surprising."
Li Fengjie and Wang Zunde understood the reason after hearing Sun Chengzong's explanation. They happened to see Zhong Jinwei look over after hearing Sun Chengzong's words, and they quickly congratulated Zhong Jinwei on his promotion.
Gongsa held it aside and heard Sun Chengzong's explanation. When he understood the origin of Zhong Jinwei, his eyes lit up. This outsider could also be a high-ranking official in the Ming Dynasty!
Zhong Jinwei didn't notice the change in Gongsar's mentality. He was chatting casually and took this opportunity to approach Li Fengjie and Wang Zunde and chat with them about the situation in Guangdong and Guangxi.
At this time, the gap between Guangdong and Guangxi was quite large compared to that of later generations. In addition, Li Fengjie and Wang Zunde would not mention the issues in their own jurisdictions, so Zhong Jinwei chatted for a long time, but nothing came out of the conversation.
Sun Chengzong listened to the three people chatting without saying a word. He was worried about the situation of the bet. He gave the paper in his hand to Wang Zunde, pulled Zhong Jinwei aside, and then lowered his voice and asked: "Is it okay to do what you did?
Is there any basis for this?"
"There must be evidence and I will say it only when I am confident." Zhong Jinwei replied with a smile.
"Tell me about it?" Sun Chengzong asked tentatively, wondering if this was Zhong Jinwei's family secret and would it be inconvenient to tell it.[
"Of course, no problem." Zhong Jinwei replied while re-demonstrating and explaining it to him.
"Stretch your arms forward, raise your thumb, close your left eye, and align your right eye's sight along the thumb side to the left side of the target. Keep your head and hands still, close your right eye again, and make your left eye's sight pass through the same side of your thumb.
side, and remember to aim your sight at a certain point on the ground, and then visually measure the width from the left side of the target to that point. Ten times this width is the distance from me to the target."
Sun Chengzong listened attentively, and after Zhong Jinwei finished speaking, he tried to do what Zhong Jinwei said.
After so many years of life experience, his estimation of length is relatively accurate. Therefore, when he gave the value of ten times the estimated distance, he saw Zhong Jinwei smiling and nodding, and he couldn't help but be happy and said: "Is it really that simple?"
"Yeah, that's pretty much it. This method is called eye-picking." Zhong Jinwei replied.
The eye-tap method is a simple distance measurement method commonly used in later armies. Zhang Taofang, an outstanding sniper from the former Volunteer Army, is best at this method.
In the sniper battle at Shangganling, the Mosin Nagant rifle used by Zhang Taofang was not equipped with a scope, and the range measurement mainly relied on visual inspection. The record of killing 214 enemies in three months also proved that he was proficient in using the jump-eye method to measure distance.
distance accuracy.
Zhong Jinwei saw the use of pillars in "Bright Sword". He thought it was strange at the time. After checking the information, he found out the reason. Then he often bet with others on guessing the distance, and won many meals for this reason.
"Is there any basis for this law?" Sun Chengzong remembered that Zhong Jinwei had never 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 arms, so by measuring ten times the width of the object on the ground, we can get the distance from where we are standing to the target." Zhong Jinwei explained.
, then turned to Gu Baichuan and said, "Lend me your knife."
Others had been paying attention to these two high-ranking officials of the imperial court. When they saw Sun Chengzong imitating Zhong Jinwei's previous actions, they knew that Zhong Jinwei was teaching Sun Chengzong. They couldn't help but be a little curious and wanted to hear what it was about.
But Sun Chengzong had pulled Zhong Jinwei aside to ask questions before, obviously not wanting them to know the content of his conversation. Therefore, they did not dare to get close.
Gu Baichuan had been looking at Zhong Jinwei. Now when he heard that he wanted to use a knife, he quickly walked over, took out the knife, turned his wrist, pointed the handle of the knife toward Zhong Jinwei, and handed it to him.
After Zhong Jinwei got the knife, he scratched it with the tip of the knife on the dry mud while explaining to Sun Chengzong: "The difference between this side and this side is ten times. This is a right angle, and this is also a right angle."
Sun Chengzong was listening at a loss. He couldn't understand what Zhong Jinwei was explaining seriously. Although he didn't understand, he knew what Zhong Jinwei said without having to guess.
There must be a basis for it, and there is nothing wrong with it.
After Zhong Jinwei finished speaking, Sun Chengzong shook his head and sighed: "I'm really old, I don't understand this." Then he noticed that Gu Baichuan was standing beside him and didn't avoid it, so he asked him: "Do you understand?"
Gu Baichuan was also confused, shook his head and said, "My subordinates don't understand either."
Zhong Jinwei returned the knife to Gu Baichuan, then clapped his hands and said, "It's not difficult, it's just a bit of mathematical geometry knowledge."
"But what is the geometry mentioned by Xu Shangshu?" Sun Chengzong knew that Xu Guangqi called geometry geometry, so he asked after hearing what Zhong Jinwei said.
Zhong Jinwei nodded: "Exactly, there is a lot of mathematical knowledge that can be used in military affairs, not just geometry."
Gu Baichuan listened on the side and thought to himself that he should study this mathematics well when he has time, it will always be useful in the future.
When Sun Chengzong was about to take stock, the guards who were measuring the distance came back. He was eager to know the final answer, so he took the lead and walked back to the crowd.[
The personal guard reported the actual measured length to Sun Chengzong. Two of Gongsar's subordinates also reported the length, and the interpreter on the other side translated it to Sun Chengzong to prevent Gongsar's misinterpretation on purpose.
The difference in length measured on both sides is very small, and this error is understandable. Everyone's eyes suddenly focused on the two pieces of paper in Wang Zunde's hand.
Sun Chengzong motioned to Li Fengjie and Wang Zunde, who were standing aside, to each take a piece of paper and read it out in front of the public.
Gongsar was very nervous. He originally didn't believe that Zhong Jinwei's results would be accurate, but when he saw that Zhong Jinwei was teaching Sun Chengzong again, he felt a little uneasy.
As soon as the answers were announced, it was found that Zhong Jinwei's answer was similar to the length measured by Gongsa Jue's subordinates, while Gongsa Jue's answer was similar to the length measured by Sun Chengzong's personal guard.
In other words, the results of Zhong Jinwei and Gonzawa are very close, almost the same, and it is impossible to tell whose result is more accurate.
Gonzago did not expect that this young high-ranking official of the Ming Dynasty could actually measure distances, and he could do it without tools.
He was very unwilling to do so. After all, it was about the salary of these people. So he said: "Just because you can measure distances doesn't mean you can fire cannons. I don't accept it."
