After sending Lang Zhong and his men away, Xia Houlan told Fu Zhu what had just happened. After hearing this, he said in a skeptical tone: "Captain Xiahou, how do you know that the other party is a fine work sent by Tinghou to Jingshi?" ”

"I saw a waist tag representing his identity." Xia Houlan explained to Fu Zhu: "The fine works sent by Jizhou everywhere have a waist card representing their identity on their bodies. On one side is written the word 'spy', and on the other side is a set of numbers representing identity, which outsiders cannot forge at all. ”

"Even if it's a fake, it doesn't matter." Wang Yun put himself under house arrest because he didn't want to interfere in Cai Yong's affairs, and the letter he wrote to Han Zhan was just to tell him about the recent situation of Jingshi and the news of Cai Yong's imprisonment, even if this letter fell into Wang Yun's hands, there would be no harm.

After the man got out of the heavily besieged inn, he immediately said goodbye to Lang Zhong, and walked around the street a few times, and only after making sure that no one was following him, did he knock on the door of a house. The man inside opened the door and saw that it was his own outside, so he let him in, but he went out, looked around vigilantly, and after making sure that there was no danger, he retreated into the house and closed the door casually.

With a stick of incense, a man on horseback came out of the back door of the house, looked left and right, and galloped towards the east.

Seven days later, he arrived in Jizhou with the letter of frustration.

Xun Yu, who was in charge of managing the fine work, hurriedly came to Guo Jia to discuss after receiving the letter from the frustrated professor: "Fengxiao, you see the letter from Gonghe, Wang Yun used a series of tactics against Lu Bu and joined forces to kill Dong Zhuo. However, what the lord was worried about still happened, and Cai Shizhong was imprisoned by Wang Yun. ”

When Guo Jia heard Xun Yu say this, he couldn't help but be shocked, and hurriedly asked for the letter he had just received, read it carefully, and then said to Xun Yu: "Xun Changshi, I think we should go to the state pastor's mansion as soon as possible and see the lord." ”

"Filial piety and slowness." Xun Yu stopped Guo Jia and said to him: "Cai Shizhong is in prison, we have to think of a countermeasure first, so that when Zhan'er asks, we can deal with it." ”

"Xun Changshi, don't worry." Who knew that Guo Jia actually laughed when he heard him say this: "As far as I know, before the lord sent Fu Gong and went to Jingshi, he explained two things to him. One is to offer a series of schemes to Wang Yun, prompting Dong Thief and Lu Bu, the righteous father and son, to turn against each other; The second is to order Fu Gonghe to find a way to persuade Cai Shizhong to come to Jizhou. Since these things had been expected by him for a long time, could he not have thought of any way? ”

After Guo Jia's reminder, Xun Yu suddenly realized that his nephew seemed to have the ability to be an unpredictable prophet, so he nodded and said, "Okay, then let's go to the state pastor's mansion now, give this letter to Zhan'er, and see what he has to say then." ”

When the two came to the state governor's mansion, they happened to meet Chen Dao, who was on duty. Guo Jia bowed to the other party and asked with a smile: "Uncle Zhi, I don't know if the lord is in the mansion?" ”

Seeing Xun Yu and Guo Jia coming together, Chen Zhi hurriedly bowed down and saluted them, and said respectfully: "The lord has never gone out in the mansion today, please come with Chen." ”

Chen Zhi led Guo Jia and Xun Yu to the outside of the study, and said politely to the two: "Please wait here for a while, and wait for Chen to go in and report to the lord." Not long after Chen entered the house, he walked out again and sat down in a gesture of invitation to the two.

Guo Jia and Xun Yu walked into the study and saw Han Zhan sitting in front of several cases, leaning over to write something. The two hurriedly stepped forward to salute: "I've seen the lord!" ”

Han Zhan glanced up at the two of them, and said with a smile, "Uncle and Fengxiao are here." As he spoke, he pointed to the side with his left hand, "The two of you will sit down for a while, and wait for Ben Hou to finish this sketch, and then talk to you." ”

Han Zhan's words aroused great interest among the two, and they did not sit down, but gathered around to see what Han Zhan was drawing. Guo Jia looked at it carefully for a while, and felt that what kind of farm tools Han Zhan painted seemed to be quite familiar, but he couldn't remember what the name was in a hurry.

Xun Yu was well-informed, and after only looking at it for a while, he asked Han Zhan tentatively: "Zhan'er, is it a cocoon car that you painted?" ”

"That's right, it's the car." Hearing Xun Yu ask, Han Zhan nodded, and then said triumphantly: "The columbine can not only complete the ditching, planting, soil covering and other operations at one time, greatly improving the efficiency of sowing, but also ensure that the row spacing is consistent, the depth is consistent, and the density is consistent, which is convenient for ventilation and light transmission and field management after emergence, so that the quality of sowing can also be improved." ……”

Han Zhan had just finished selling the knowledge he knew to the two, and suddenly he realized that something was wrong, and hurriedly asked Xun Yu: "Uncle just said that this kind of farm tool is called a cocoon car, has he ever seen this thing before?" ”

"That's right." Xun Yu nodded and said, "This farm tool was available to me a hundred years ago." Unfortunately, the cost is too high to be popularized. ”

Hearing that this kind of farm tool had been available for a long time, Han Zhan couldn't help but blush with shame, he originally wanted to tell the two that this was a farm tool he had invented. Fortunately, Xun Yu said the name of this farm tool first, otherwise he would be embarrassed.

Han Zhan hurriedly coughed heavily, put this drawing aside, and put another drawing that had been drawn a long time ago in front of the two of them, and asked, "I wonder if you two have ever seen this thing?" ”

Xun Yu stared at the drawings for a long time, then shook his head and said, "I've never seen this thing." Then he turned his head and asked Guo Jia, "I don't know if Feng Xiao can recognize this thing?" ”

Guo Jia smiled bitterly and replied, "Jia has never seen this thing, it must be a new thing that the lord just came up with." ”

Seeing that the two did not recognize the stirrup he had drawn, Han Zhan became proud again, and he explained to the two: "This thing is called a stirrup." It is a pair of pedals hung on both sides of the saddle for the rider to use as a harness for riding when he gets on the horse and when riding. Its role is not only to help people get on the horse, but more importantly, to support the rider's feet when riding, so as to maximize the advantages of riding a horse, and at the same time effectively protect the safety of the rider. ”

When Guo Jia heard Han Zhan say this, he hurriedly picked up the drawings and looked at them carefully, while making up the details of what Han Zhan said. After he organized the words to be said in his mind, he handed the drawing to Xun Yu on the side, and then asked tentatively: "I wonder if the lord has prepared this stirrup for the army?" ”

"Bonghyo guessed right." Han Zhan nodded and admitted, "That's exactly what Ben Hou thought about. ”

"It's wonderful." Xun Yu pointed to the drawings with his fingers and said to Han Zhan excitedly: "Our army's horses were nailed to the horseshoe a few months ago, which reduced the daily wear and tear of the horses. With this stirrup at the moment, it is really a tiger with wings. In time, my Jizhou will definitely be able to train an invincible iron horseman. ”
