Although the vat under the city can clearly hear the sound of the enemy marching, the enemy army can not be seen on the city wall for the time being, so Zhu Youcheng and King Xin still have time to chat, as for the mobilization of artillery to defend the city, that is Wu Huping's business.

King Shin asked a little puzzled, "Brother Cheng, why are you not surprised that the vat can hear the movement of the enemy?" ”

Zhu Youcheng said with a smile: "Originally, I should have said this matter in the "Science" class of Tongle Primary School, but there are too many things, and the "Science" textbook has not been revised, and the knowledge of sound has not been added for the time being. In fact, sound can not only travel in the air, but also in water and soil. For example, if someone is diving, we call him, and he can hear it, which means that sound can also be transmitted in the water. Soil and rocks have a stronger ability to transmit sound. For example, if you put a stone against your ear and gently scrape the stone, your ear can hear a loud sound, and if you move the stone a little farther away, the sound will be much quieter. This is the principle of burying a large vat in the soil and being able to hear the sound of the enemy's movements. What's even better is that the vat is round, it has a concentrating effect, it can bring the sound together, which is equivalent to amplifying the sound, so that you can hear small sounds in the distance......"

Cai Fuyi and Fu Zonglong couldn't help but nod their heads again and again when they heard this.

Cai Fuyi praised: "It is worthy of being the champion Lang, he knows everything about astronomy and geography, knows everything about the three religions and nine streams, and he actually knows the principle of the big vat of sound gathering." The two of us only know what it is, but we don't know why. ”

Zhu Youcheng, a hypocrite, has to be humble again.

At this moment, Wu Huping said, "My lord, the enemy army has appeared. ”

Zhu Youcheng picked up the telescope and looked into the distance, only to see that there were flags waving, and a large army was marching towards Guiyang with firm steps.

"When did the rebels become so aggressive? He also came to fight with a flag. Zhu Youcheng muttered a little strangely.

Cai Fuyi and Fu Zonglong saw Zhu Youcheng, Xinwang, Wu Huping, and Ke Qingqing each holding a strange item made of brass and looking into the distance, not knowing what they saw. was so anxious that he scratched his ears and cheeks, and he didn't take into account the decency of the important ministers of the court.

Fu Zonglong, relying on his age, snatched the telescope in Zhu Youcheng's hand and said, "Borrow the old man to take a look." ”

There is a lanyard on the telescope, which is put around Zhu Youcheng's neck to prevent accidentally breaking the telescope. When Fu Zonglong grabbed the telescope. didn't notice the lanyard, this robbery, the lanyard tightly strangled Zhu Youcheng's neck, strangled his tongue out, and he was not strangled to death. Zhu Youcheng is a martial champion, with his skills, with a beautiful over-the-shoulder fall, he can subdue Fu Zonglong and snatch the telescope back. But Fu Zonglong is getting old. If you really want to fall, you'll be in trouble. So Zhu Youcheng grabbed it for a long time before snatching the telescope back.

Fu Zonglong muttered in a low voice: "I won't let you borrow it, it's really stingy." ”

Zhu Youcheng first gasped for breath, then pointed to the red mark on his neck and said: "This official did not die in the hands of Jiannu and the rebels, but almost died in the hands of you, a loyal minister of the Ming Dynasty." If you want to borrow it, just say it, what does it mean to grab it. Huping, show your binoculars to Master Fu—no, show them to Master Cai first. Show it to Master Fu again, pay attention. I'm just borrowing him to see it, and I'm going to take it back. ”

Zhu Youcheng's sense of revenge is still very strong, isn't Fu Zonglong in a hurry to watch? I finally showed him and killed him in a hurry.

Cai Fuyi took the telescope and looked in the direction of the army following Zhu Youcheng's example, but found that it was clear, but the scene became smaller. You might as well not use a telescope.

Wu Huping reminded in a low voice: "Lord Cai, take it upside down." ”

Cai Fu turned over the telescope, looked closer to him, and couldn't help but say, "Master Fu, maybe we guessed wrong." ”

said. He handed the telescope to Fu Zonglong.

Fu Zonglong took the binoculars, looked at them carefully for a while, and said, "Yes, it's not a rebel, but it looks like the army of the Ming Dynasty." ”

Fu Zonglong returned the telescope to Wu Huping, and then said to Zhu Youcheng: "Lord Zhu, the army seems to be a friend rather than an enemy." ”

Zhu Youcheng nodded and said, "I saw it." However, I am also afraid that the enemy army will change into the clothes of our army and then come to the city, so it is better to be careful. ”

After a while, the army was getting closer and closer to Guiyang City, and the people on the city wall could clearly see the faces of the front-row soldiers without binoculars.

Zhu Youcheng observed for a long time and said: "The army is strict and orderly, and the military discipline is strict, it is indeed like the army of the Ming Dynasty." However, they were only allowed to enter the city after careful interrogation. Guiyang is the capital of Guizhou, and the significance of politics is extraordinary, and there is no room for mistakes. ”

Everyone nodded in unison.

The opponent's army set up a formation outside Guiyang City, rode over, and when he walked to the gate of the city, he said loudly: "The Ming Military Department is still in the book, and the military affairs of Guangxi, Yunnan, Guizhou, and Sichuan provinces Zhu Xieyuan Zhu has arrived, who are you?" ”

Governors of the four provinces? Zhu Youcheng once again changed history. Historically, Zhu Xieyuan did serve as the governor of the four provinces and the secretary of the military department, but this military secretary was an additional title, which was just convenient for him to dispatch the army in the southwest, and it did not mean that he had taken the position of the boss of the military department. The boss of the military department is still Li Chunye, because of Zhu Youcheng's hospitality, Li Chunye did not succeed and remained in the military department.

The envoy's words sounded strange at first glance, but Zhu Youcheng looked at the charred city walls and burned towers, and couldn't help but smile bitterly, such a Guiyang city really looked like a city that had been breached, no wonder the envoy would ask who they were.

King Xin grabbed the iron horn in the hands of his own soldiers and shouted to the city: "King Daming Xin, Daming Longtuge University Scholar, Daming Hanlin Academy Bachelor, Daming School of Administration, Daming Military Academy, Daming Jinyi Guard Commander Zhu Youcheng Zhu is here." ”

Hearing that there was a military secretary, King Xin's competitive spirit rose again, and all of Zhu Youcheng's official positions were reported.

Zhu Youcheng has too many official positions, and King Xin finished reading it in one breath, but he didn't breathe, it seems that after he exercised in Jingxi Huangzhuang, his body was much better.

Cai Fuyi and Fu Zonglong saw the horn in King Xin's hand, and their eyes were full of envy. Jinyiwei's equipment is really good, there are binoculars that can see in the distance, and there are horns that can amplify sound. It's a pity, looking at Zhu Youcheng's stinginess, these things can only be seen but not touched.

The messenger hurried back again, presumably to report to the commander of the army.

In a short time several horses came out at the same time, and the one in the middle was probably the highest, and I saw that he was about sixty years old, with gray sideburns and a big beard that was shiny black.

He came to the city, raised his head and said loudly: "This official is Zhu Xieyuan, can you ask Master Zhu Youcheng Zhu to come out and talk?" ”

Fu Zonglong once saw Zhu Xieyuan and carefully identified it, it was indeed Zhu Xieyuan.

Fu Zonglong's proof made Zhu Youcheng feel at ease, and boldly took King Xin out of the city to see Zhu Xieyuan.

Guiyang City is on guard against Zhu Xieyuan, why isn't Zhu Xieyuan on guard against Guiyang City? Since Zhu Youcheng has determined that the person who came is Zhu Xieyuan, he naturally has to be more frank, if it causes misunderstanding on the other side, then it will not be worth it.

Zhu Youcheng rode a yellow fat horse, King Xin rode a white horse, and the two went out of the city together.

Zhu Xieyuan looked at it carefully, ho, the two beautiful young men are indeed like the two in the legend. He gave way to a white-faced, beardless man behind him. When the man saw Zhu Youcheng, he said in surprise: "Master Zhu, I haven't seen you for a long time, but I want to die in our family." ”

Zhu Youcheng looked at it and was happy, sure enough, it was an old acquaintance, the Imperial Horse Supervisor Palm Seal was too close to Tu Wenfu, it seemed that the Emperor of the Apocalypse had arrested him again.

Zhu Youcheng asked with a smile: "Father-in-law Tu, is it another eight-hundred-mile urgency?" ”

Tu Wenfu also smiled: "Not bad." The emperor heard that Guiyang City was besieged by 200,000 rebels, and he was worried about the safety of you and King Xin, so he specially sent our family to Chengdu to move troops. This is Zhu Xieyuan Zhu, the number one hero in the defense of Chengdu. It was he who blocked the pace of luxury Chongming's march and kept the capital of Sichuan. The emperor sent him to assist Lord Zhu in exterminating the rebels. ”

Seeing Tu Wenfu mention himself, Zhu Xieyuan said with a smile: "However, I see that there is no enemy outside Guizhou City, I think it was the enemy army who heard that we came to help, and they were so frightened that they fled far away." ”

Before Zhu Youcheng could speak, King Xin preemptively said, "It's not." An Bangyan, the old thief's 200,000 enemy troops, has been defeated by Brother Cheng, and even this old thief has been captured by Brother Cheng. ”

Zhu Xieyuan's horsewhip fell to the ground.

He knew that the rebels in Sichuan and Guizhou were just a rabble, but although the quality was not good, the quantity was there, 200,000, and he was a little weak, why did Zhu Youcheng defeat them so easily? Could it be that An Bangyan's brain suddenly flooded and made all the rebels stand still and let the Jinyi guards cut it?

Zhu Xieyuan couldn't help asking, "What's going on?" ”

Zhu Youcheng smiled: "Lord Zhu, let's go to the city to talk." ”

He was full of respect for Zhu Xieyuan, and in the historical time and space without him, it was Zhu Xieyuan who finally quelled the Extravagant Rebellion and returned stability to the southwest. (To be continued......)
