It was too late, so Zhu Youzhen and Guocheng decided to stay overnight in the guard. Guocheng asked the newly enlisted Jinyi guards to go home to rest, and gathered at the parade platform at the fifth watch tomorrow morning, and made a special statement that those who arrive late will be dismissed immediately.

Wu Tianmeng set up a banquet to entertain them, and when they were staggering, Guocheng and Zhu Youzhen were a little drunk. Of course, Guocheng and Zhu Youzhen drank not wine, but honey water. Ruan Dacheng was really at home on this occasion, and he had a hot fight with Wu Tianmeng and Feng Yu for a while.

Halfway through the meal, Guocheng remembered that Ke Qingqing was eating in the inner house. Sneaking in to take a look, Ke Qingqing chatted happily with Wu Qianhu and Feng Yu's family. Seeing Guocheng, the expression on Ke Qingqing's face instantly turned from sunny to cloudy, and there seemed to be water in his eyes, looking unaggrieved and sad. If it weren't for Guocheng's sharp eyes, he might have been fooled when he saw Ke Qingqing talking and laughing before he saw him.

Guocheng said with a smile: "Why was it sad to see me, I knew that I wouldn't come to see you." ”

Seeing that it was exposed, Ke Qingqing complained a little annoyed: "Can you not be so smart? ”

Before the fifth watch of the next day, Guocheng dragged the sleepy-eyed Zhu Youzhen to the parade platform. I thought I was the earliest, but I didn't expect that there were already shadowy figures in front of the parade platform. It's really Mo Daojun who walks early, and there are even more early pedestrians.

Guocheng originally wanted to catch a few typical Liwei, but he didn't expect that the military remnants in the guard station dreamed of participating in the Jinyi Guard, how could he be willing to lose this hard-won opportunity, and he waited here early before the fifth watch arrived. Guo Cheng and Zhu Youzhen became the last to arrive at the parade platform.

Since everyone had arrived, Guocheng asked them to line up, divide into two groups, and walk to the capital on foot. Because Chen Guoqi was the first person to take the test, and Wu Huping had the best score in the test, they were asked to serve as the temporary general flag, and each led a group. According to the military system, the hundred households have no right to appoint the general flag, but Guocheng, the hundred households, has never been to the Jinyi Guard to report for duty, nor has he been to the Jinyi Guard on duty, and this time the Jinyi Guard was recruited by him with full authority, so Guocheng only did not have this military rule, so he gave the order. It made Wu Tianmeng and Feng Yu, who came to see them off, muttered in their hearts, this hundred households wearing flying fish suits are so majestic.

Guocheng left ten guards to lead the recruits to the capital, and he got into the carriage with Zhu Youzhen, Ke Qingqing, Wang Chengen and Ruan Dacheng. Guocheng wanted to lead by example and personally accompany them on the walk, but Zhu Youzhen resolutely disagreed, and he was only 7 years old, and his body was much worse than that of a 12-year-old boy, so he didn't insist.

A few people were chatting with each other, when suddenly two people on the side of the road waved for a ride. Both men dressed as scribes, one was an old man in his fifties, and the other was a middle-aged man in his thirties. Although the two of them were dusty, their eyes were shining, and they were obviously not ordinary people. Guocheng saw that there was still a vacant seat in the car, and saw that the two of them were extraordinary, so he let them take a ride.

The middle-aged scribe's eyes were bright, and he saw at a glance that Guocheng was the person in charge of this group of people, so he said: "Thank you for this little prince, I am from Songjiang Mansion, surnamed Xu Guangqi, because of the overnight hurry, Male was sick, fortunately I met the little boy, otherwise I would have to go to the capital." ”

Guocheng's eyes lit up, wow, cow man, the greatest scientist in the late Ming Dynasty, who opened his eyes to see the world earlier than Lin Zexu, the first person in modern Chinese history to open his eyes to see the world, translated Euclid's "Geometric Originals", and wrote many scientific and technological works. The one next to him must be Sun Yuanhua, a famous artillery casting expert in the Ming Dynasty, and a cattle man.

Guocheng hurriedly stepped forward, bowed, and said, "Guocheng has seen Mr. Xu." ”

After speaking, he hurriedly pulled Zhu Youzhen's clothes and asked him to give Xu Guangqi a salute.

Xu Guangqi saw that the two of them saluted him, recalled the content of the holy decree, and was unhappy, he had worked hard for more than 20 years, and did not seek any welfare for the people, but wanted to be the teacher of the Taiping Prince, and remembered the rumors of Guocheng, and saw him wearing a flying fish suit vividly, he couldn't help but snort heavily, and asked: "Perfume hundreds?" ”

Guocheng smiled bitterly in his heart, is his rumors so unbearable? Thinking that if he couldn't quickly convince Xu Guangqi, he would not do his best for the emperor's grandson, and he would live up to the emperor's kindness, so he asked: "The diameter of the wellhead is one foot, what is the area of the well?" The well is one foot deep, if the well water overflows to the wellhead, how much well water is there? ”

Xu Guangqi was shocked, he would do the first question, and there were relevant formulas in his translation of "Geometric Originals", but the second question belonged to three-dimensional geometry, which was the content of the last nine volumes of "Geometric Originals", and he had not yet had time to translate it.

Guocheng said again: "3.1415926"

Everyone didn't understand what it meant, but Xu Guangqi understood as soon as he heard it, this is pi, and it is pi to 7 decimal places.

Guocheng continued: "The area of a rectangle is the length multiplied by the width, the area of the square is the length of the sides multiplied by the length of the sides, the area of the triangle is the base multiplied by the height divided by 2, and the area of the trapezoid is the sum of the top and bottom multiplied by the height and divided by 2. ”

Xu Guangqi was shocked, this 7-year-old little doll mastered no less mathematical knowledge than himself, so he couldn't help but stand up and salute Guocheng: "Xu Mou hearsay, offended the son of the country, please forgive the son." ”

Guocheng hurriedly returned the salute: "Guocheng is a little boy, how can he be worthy of Mr. Xu's courtesy." ”

Xu Guangqi said: "There is no order to learn, and the master is the teacher." Guangqi did not salute because of the status of the prince and the imperial grandson, but was impressed by the profound knowledge of the child. ”

Guocheng looked at the middle-aged man next to him: "Is this gentleman Sun Yuanhua from Songjiang Mansion?" ”、

The middle-aged man was taken aback and said, "Xiao Ke is a nameless person, I can't imagine that the prince of the country can actually recognize him." ”

Guocheng said: "Mr. Sun is a genius of the Ming Dynasty, and I admire Mr. very much." ”

Sun Yuanhua said: "What does Gongzi think of artillery. ”

Guocheng said: "The power of the artillery is strange, the range is long, and the damage is great. ”

Sun Yuanhua nodded in agreement and said, "I think the court should vigorously cast cannons, especially in the border areas......"

When Sun Yuanhua talked about artillery, he talked about it as if he had a foot, and talked with Guocheng as if no one was around. Xu Guangqi couldn't help but shake his head when he saw this, this Sun Yuanhua, everything is good, but he can't mention the artillery in front of him, as soon as he mentions the artillery, his word box will be opened, and you will never stop if you don't stun.

During the conversation, I had already entered the city of Beijing. It was two days after the recruits arrived in Beijing City, and the young man's body was not good after all, and the progress of the line was too slow. Guocheng arranged the recruits in Ningyuanbo's Mansion, which is now called Guofu. Guocheng pretended to be public and private, transferred the masons and blacksmiths to the national government, and repaired them well, but in fact, it could not be regarded as repair, mainly demolition. Guocheng is like a cow running to the peony garden, tearing down all the beautiful buildings, and only building a row of barracks on the side, all of which are bulldozed in the middle to become a huge training ground.

The surrounding residents can suffer, some time ago there were a large group of unknown people to visit here, pointing and pointing, although it is noisy, but a little moderation, the wind and rain do not come, no one after the curfew. But since the national government was changed to a training ground, rain or shine, day and night, it was either the sound of rushing and killing, or the sound of Lang Lang's book, which still made people live?

Guocheng heard that his neighbors had opinions, so he hurriedly apologized door-to-door, and sent a bottle of perfume to each household, so that he finally blocked Youyou's mouth.

Rao is like this, the training ground is still causing trouble.
