In order to promote kimchi as soon as possible, Han Zhan ordered someone to give the prepared kimchi to Jizhou Wenwu and some close ministers in the DPRK and China. In less than half a month, the production method of southern kimchi spread in the capital of Ye, whether it was court officials or ordinary people, they were learning to make kimchi.

The prosperity of the kimchi industry in Yedu City, the biggest benefit is the boss of the roast pinxuan, to his shop to customize the kimchi jar of the dignitaries and nobles in an endless stream, so that his home has been idle for a long time in a few tile kilns, every day is blazing, but also specially recruited more than a dozen potters, day and night non-stop firing, but still in short supply.

The boss of Roast Pinxuan, who got the benefits, also specially enshrined Han Zhan's immortal tablet at home, and he had to worship his family sooner or later, praying that God would let Han Zhan live a long life, so that he could bless himself with a prosperous business.

Han Zhan didn't know that the boss of Burning Pinxuan had enshrined his immortal tablet at home, and he was thinking about how to use it to achieve long-distance communication.

Just pondering, Rob came in to report: "Lord Qi, the military advisor asks to see!" ”

Guo Jia now regards Han Zhan's state mansion as his home, not only to watch Huangmei Opera every day, but more importantly, to eat. Not only can I say it, Han Zhan is the most powerful person on the ground in Jizhou, and the people who come to please him every day are lining up outside, and the various food things sent are even more dazzling, Guo Jia came here just to be able to taste unexpected deliciousness at any time.

Seeing Guo Jia enter the door, Han Zhan suddenly asked thoughtlessly: "Fengxiao, Ben Hou asks you, is there any way to send back the information thousands of miles away in the shortest possible time, or to spread the information here?" ”

Guo Jia thought for a while and replied: "If you go back to the lord, you can use carrier pigeons, and the message from thousands of miles away can be transmitted back in two days at most!" ”

"No, it's too slow." Han Zhan shook his head and said: "The carrier pigeon is actually the most unreliable, it is possible to get lost in the middle of the way, or it may be hunted by natural enemies, and then it will delay the big thing." ”

"Then we can communicate through the station." Guo Jia saw that Han Zhan denied his statement, and after a short thought, he continued: "Six hundred miles is urgent, and you can receive a message thousands of miles away in two days. ”

"No, it's still too slow." But after hearing this, Han Zhan continued to shake his head: "We receive the information here, and then feedback back, it will take four days at the earliest." If it is an alien attack from the north, it will take two or three days to get the information, which is too slow. ”

"My lord," Han Zhan's words made Guo Jia confused: "If the alien race comes to attack, the border guards will be able to report through the beacon tower, even if it is thousands of miles away, at most an hour or two, we can get the information here." ”

"When you see the beacon fire in the distance, you can only know that there is an enemy coming. But how many enemies are coming, and where they entered the customs, we still can't know in time......" As soon as Han Zhan said this, his mind suddenly flashed, and he suddenly thought of a communication method similar to a beacon tower, so he slapped it on the table hard, and said excitedly: "Military advisor, what a word to wake up a person in a dream, Ben Hou knows how to contact thousands of miles away in the shortest possible time." ”

Seeing Guo Jia's dazed expression, Han Zhan said triumphantly: "Strategist, if Ben Hou tells you that there is a way to get information thousands of miles away in the time of two incense sticks, can you believe it?" ”

"With two sticks of incense, you can know things thousands of miles away?" Guo Jia heard Han Zhan say this, and asked cautiously: "Could it be that the lord is talking about thousands of miles of sound?" But this kind of thing can only be done by talented people, and ordinary people still can't do it. Do you need your subordinates to send someone to find such a talented person? ”

"Who said that you have to be able to be different, even if you are an ordinary person." Han Zhan saw that Guo Jia looked suspicious, so he said to him: "Like building a beacon tower, we will build a high platform every mile on the high place, and place a soldier with a flag on it. We sent someone to turn the message into a flag and pass it on to the soldiers on the high platform a mile away, and after the soldiers saw the flag, they sent the same flag to the soldiers on the next high platform. By analogy, the message we want to send will be quickly transmitted to the distance through the banners of the soldiers on the high platform. ”

After Guo Jia listened to Han Zhan's introduction, a shocked expression appeared on his face: "Lord, you are really a genius, you can actually come up with such a wonderful method." You must know that the beacon can only play the role of a warning, but the method of the lord can transmit accurate information thousands of miles away in the shortest possible time, which is simply wonderful. ”

Speaking of this, Guo Jia stood up and said to Han Zhan respectfully: "If the lord can trust his subordinates, he can hand over this matter to his subordinates. The subordinates must build a high platform leading thousands of miles away within two months. ”

"In order to ensure the accuracy of the information," Han Zhan saw that Guo Jia was willing to take the initiative to take the matter, and did not object, but explained his work to him: "The interval between the high platforms should not exceed one mile, so that the soldiers on the high platforms can clearly see the flags from the previous high platform and accurately transmit them to the next high platform." ”

"And how many soldiers should be deployed on each platform?"

"One high platform, three people are enough." Han Zhan replied: "If you encounter any uneven areas, you should be equipped with at least one or more people in the high platform you build, so as not to be powerless to resist when attacked." ”

Guo Jia understood what Han Zhan meant, and the high platforms established in Jizhou were enough for three people per platform. But if it is Qingzhou and other newly acquired places, the people's will is not stable enough, if there are only three people in each high platform, once they are attacked, it is estimated that they will be wiped out in an instant, and hurriedly replied: "Please rest assured, my subordinates will definitely handle this matter." ”

"Fengxiao," Han Zhan continued to advise, "Now is the cold winter wax moon, and it is also the time of farming. You can recruit people to do the work of building high platforms, and remember to give them more money and food. Only when they have food in their stomachs will they work harder. ”

"Lord, please rest assured," Guo Jia hurriedly replied: "Not only Jizhou or Qingzhou, but when the farming season is slack in winter, many people will have problems with their livelihoods, and they want to earn more money to supplement their families." If I had known that the lord was willing to pay for food and recruit people to build the high platform, I think there would have been many people rushing to do it. ”

Knowing that there would be many people to participate in the construction of the high platform, Han Zhan's heart was still quite happy, and he continued: "Build the high platform leading to Qingzhou first, not only to say it, but it is all newly harvested land, the people's hearts are unstable, and there are some officials who are not in harmony with us, so it is very important to understand the information there in time."

After repairing the high platform leading to Qingzhou, the high platform to the north was repaired. After the beginning of spring, the war between us and Gongsun Chan is inevitable, and with the high platform, we can understand Gongsun Chan's movements in a more timely manner. The so-called: knowing oneself and knowing the other side will win all battles, and only when we understand the reality of the other side can we not suffer losses after the war. ”
