It was too late, and Zhu Youjian and Guocheng decided to stay in the military office. Guocheng asked the newly enlisted Jinyiwei to go home to rest, and gathered at the parade platform tomorrow morning at the fifth day of the morning. He made a special statement that those who were late would be dismissed immediately.

Wu Tianmeng held a banquet to entertain them. When the wine was toasting, Guocheng and Zhu Youjian were a little drunk. Of course, Guocheng and Zhu Youjian did not drink wine, but honey water. Ruan Dacheng was really like a fish in water on such occasions, and he had a hot fight with Wu Tianmeng and Feng Yu in a while.

Halfway through the meal, Guocheng remembered that Ke Qingqing was having a meal in the inner house. When he slipped in, he saw that Ke Qingqing and Wu Qianhu and Feng Yu's family were chatting happily. When he saw Guocheng, Ke Qingqing's expression instantly turned from sunny to dark, and his eyes were filled with water. He looked like he was not sure how wronged or sad it was. If Guocheng hadn't seen Ke Qingqing chatting and laughing before he saw him, he might have been fooled.

Guocheng said with a smile: "Why is it sad to see me? If I had known, I would not have come to see you."

Seeing that it was exposed, Ke Qingqing complained a little annoyed: "Can you be less smart?"

Before the fifth day of the next day, Guocheng dragged Zhu Youjian, who was sleepy, to the parade platform. He thought he was the first to come, but he didn't expect that there were already shadows in front of the parade platform. Don't tell me that you were going early, and there were even early people.

Guocheng originally wanted to capture a few typical examples to establish his authority, but he did not expect that Jun Yu in the ward station had always dreamed of joining the Jinyiwei, so how could he be willing to throw away this hard-earned opportunity? He waited here early before the fifth day of the day. Guocheng and Zhu Youjian became the last person to arrive at the parade platform.

Since all the people were here, Guocheng asked them to line up and divide them into two groups and walk to the capital. Because Chen Guoqi was the first person to take the test, and Wu Huping performed the best in the test, they were asked to serve as the temporary general flag and command one group. According to the military system, the hundred households had no right to appoint the general flag, but Guocheng, the hundred households, had never reported to the Jinyi Guard, nor had they been on duty at the Jinyi Guard. This time, the Jinyi Guard was recruited by him with full authority, so Guocheng only thought that there was no such military rule and ordered it. Wu Tianmeng and Feng Yu, who came to see him off, were confused in their hearts that this hundred households in flying fish suits were so powerful.

Guocheng left ten guards to lead the recruits to the capital, and he and Zhu Youjian, Ke Qingqing, Wang Chengen and Ruan Dacheng got on the carriage. Guocheng wanted to set an example and walk with them in person, but Zhu Youjian firmly disagreed. Moreover, he was only 7 years old and his physical strength was much worse than that of a 12-year-old boy, so he did not persist.

Several people were chatting together, and suddenly they found two people on the side of the road, waving to take a ride. Both of them were dressed as scholars, one was an old man in his fifties and the other was a middle-aged man in his thirties. Although the two were dusty, their eyes flashed, which was obviously unusual. Guocheng saw that there was still a space in the car, and saw that the two were very demeanor, so he asked them to take a ride.

The middle-aged scholar had a bright vision and saw at a glance that Guocheng was the head of the group of people, and said, "Thank you, this young master. I am from Songjiang Mansion, my surname is Xu and Guangqi. Because I was rushing all night, Ma Le was sick. Fortunately, I met the young master, otherwise I would have gone to the capital."

Guocheng's eyes lit up, wow, awesome, the greatest scientist in the late Ming Dynasty, was better than Lin Zexu, the first person in modern Chinese history to see the world open his eyes and open his eyes to see the world. He translated Euclid's "The Origin of Geometry" 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 another great man.

Guocheng hurried forward, bowed and said, "Guocheng has met Mr. Xu."

After saying that, he quickly pulled Zhu Youjian's clothes and asked him to greet Xu Guangqi.

When Xu Guangqi saw the two saluting him, he recalled the contents of the imperial edict and felt unhappy. He had worked hard for more than 20 years in the imperial examination. He did not seek any benefits for the people. Instead, he wanted to be the teacher of Prince Taiping. He also remembered the rumors about Guocheng. Seeing him wearing a flying fish suit with a spirit, he couldn't help but snorted heavily and asked, "Perfume Hundred Houses?"

Guocheng smiled bitterly in his heart. Could it be that his rumors were so unbearable? He also thought that if he could not quickly impress Xu Guangqi, he would not do his best to do his best for the emperor's grandson, so he asked: "The diameter of the wellhead is one foot, how much is the area of ​​the well? The depth of the well is one foot. If the well water floods the wellhead, how much is the well water?"

Xu Guangqi was shocked. He could do the first question. There were related formulas in the "Geometric Original" he translated, but the second question belonged to three-dimensional geometry, which was the content of the last nine volumes of "Geometric Original", and he had not 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, that this was pi, and it was pi at 7 decimal places.

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

Xu Guangqi was shocked. The 7-year-old baby mastered mathematical knowledge as much as he did. He couldn't help but stand up and bowed to Guocheng and said, "Xu said it from the truth that he offended the Prince of Guo, please forgive me."

Guocheng hurriedly returned the tribute: "How can Guocheng, a little boy, afford Mr. Xu's gift?"

Xu Guangqi said seriously: "There is no order of learning, and those who are good at learning are teachers. Guangqi is not celebrating because of the identity of the prince and the emperor's grandson, but is impressed by the prince's extensive knowledge."

Guocheng looked at the middle-aged man next to him and said, "Is this gentleman Sun Yuanhua from Songjiang Prefecture?"

The middle-aged man was shocked and said, "Young man, the nameless man, didn't expect that the prince of the country would recognize him."

Guocheng said: "Mr. Sun is a genius of artillery casting in the Ming Dynasty. I admire him very much."

Sun Yuanhua said: "How does the young master view artillery."

Guocheng said: "The artillery is powerful, has a long range and a lot of damage. If you shoot one shot, no matter what elite soldier in the world will turn into powder."

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

When Sun Yuanhua talked about artillery, he was like a clockwork, and he started talking to Guocheng as if no one else was around. Seeing this, Xu Guangqi couldn't help but shake his head. Sun Yuanhua is good at everything, but he just can't raise the artillery in front of him. When he mentioned the artillery, his words opened. You will never give up if you don't tell me.

During the conversation, he had already entered Beijing City. Two days later, the young man's physical strength was not good after all, and his speed was too slow. Guocheng arranged the recruits in Ningyuan Bo Mansion, and now he was called Guo Mansion. Guocheng used public service to private affairs, transferred the mason and blacksmith to the Guo Mansion, and repaired it carefully. In fact, it could not be considered a renovation. It was mainly based on demolition. Guocheng seemed to be a cow running to the Peony Garden, demolishing all the beautiful buildings, and only built a row of barracks on the side, flattening them all in the middle, forming a huge training ground.

The residents around were in trouble. Some time ago, a large group of unknown people came here to visit and pointed and pointed. Although they were quarreled, they were somewhat restrained. They did not come when they were windy or rainy, and no one was there after the curfew. But since the National Palace Museum was changed to a training ground, it has been stormy and rainy, and it has been endless day and night, either the sound of rushing or the sound of books. Does this make people live?

When Guocheng heard that his neighbor had any objections, he quickly apologized from door to door and gave each household a bottle of perfume, which finally blocked Youyou's mouth.
