Cai Yan heard Han Zhan mention his father, and couldn't help but sigh and said, "Tinghou, the slave family has not seen his father for three years since he married into the Wei family, and I really want to rush to Chang'an to reunite with my father immediately." ”

Han Zhan thought to himself that Cai Yong only had a few months left to live, and if you rush over now, maybe you can see the last time. But at the same time, he also puts himself in danger, if Wang Yun engages in Zhulian when he kills Cai Yong, I'm afraid your life won't be saved. In order to prevent Cai Wenji from being in danger, he decided to stabilize the other party first: "Zhaoji don't be anxious, you go back to Jizhou with Benhou to live for a while, and when Benhou enters Beijing to face the saint in the spring of the next year, he will take you to Chang'an, and then you will be able to see Ling Zun." ”

Hearing that he would have to wait for a few months, Cai Yan couldn't help but look gloomy: "In this way, I still have to wait a few months before I can see my father." ”

In order to make Cai Yan happy, Han Zhan cleverly chanted a poem by Li Bai to her: "The beauty rolls the beaded curtain and sits deeply with frowning eyebrows." But when I saw the tears wet, I didn't know who I was thinking. He deliberately replaced the word "hate" in the last sentence with the word "read".

Cai Yan's attention was really attracted by Han Zhan, she glanced at Han Zhan with resentful eyes, and said, "Tinghou also lied to the slave family, saying that you don't know how to recite poems. Yesterday's seven-word poems, Fang Cai's five-word poems, are not ordinary people can make. It seems that Tinghou has always been deeply hidden. ”

Han Zhan got up and walked to Cai Yan's side and sat down, wrapped his hand around her fragrant shoulder, and said with a hippie smile: "Actually, Ben Hou has always been a person who does not learn and has no skills, but when he saw such a beautiful and talented woman as Zhao Ji, he immediately felt like a spring of thought, and such poems couldn't help but blurt out." After speaking, he leaned close to the other party's cheek and wanted to kiss Xiangze.

At this moment, Rob's voice sounded outside: "Qiyu Pavilion Marquis, Mr. Guo invites you to the conference hall to discuss important matters." ”

Han Zhan reluctantly let go of Cai Yan, who was being held by him, and said outside: "Got it, I'll go now." ”

Cai Yan glanced at him with disgust, gently pushed him with his hand, and said softly: "Tinghou, you have something to do, so go get busy first." The slave family is also going back in a hurry. ”

Han Zhan thought that Cai Yan lived in his backyard, and the cooked duck would definitely not fly away, so he smiled and nodded: "Zhao Ji, then you will go back to the room first, and then visit you after Ben Hou finishes handling business." ”

…………

When Guo Jia and the others saw Han Zhan enter the conference hall, they hurriedly stepped forward to salute.

Han Zhan waved his hand at them, signaling everyone to be exempt, and then asked Guo Jia: "Fengxiao, I don't know if it's for the sake of the high school lieutenant?" ”

"That's right," Guo Jia nodded, "Although the assassination of the senior lieutenant is not life-threatening, we should continue to search for the assassins hiding in the city, so as not to assassinate other officials." Also, we originally planned to continue to serve as the guard general of the pavilion after the class teacher, but judging from his current situation, he may not be qualified for this position, so we also ask the lord to make plans as soon as possible and arrange other manpower. ”

Han Zhan's gaze swept over the generals standing on the side one by one, and he was thinking about who to keep as the guard of the pavilion. Zhao Yun is definitely not good, so in the next battle of the Eastern Expedition to Qingzhou, he is still needed to command the troops; Huang Zhong, no, he and Zhao Yun are the best partners, if the two of them are in charge of the Eastern Crusade, they will definitely be able to get twice the result with half the effort. Dian Wei, it's not bad to be a personal bodyguard, but if he is allowed to be alone, his ability will be a little insufficient; Jiang Qi, Lu Kuang, Lu Xiang and others had just surrendered, even if they verbally said "no doubt about employing people", it was a bit too risky to let any of them serve as the guards of the pavilion.

After some consideration, Han Zhan decided to have Xiahou Lan come to serve as the general of the pavilion Tao. Originally, according to his plan, Xia Houlan, Chu Ge and others had to be with him at all times, these two were his future brothers-in-law, and they couldn't be put in danger. But at present, there is really no one available, so I can only catch the ducks on the shelves, and let Xia Houlan temporarily act as the Tao Shou General of the Pavilion.

Han Zhan shouted at the queue of generals: "Where is Xiahou Lan?" ”

"The last general!" Xia Houlan strode out of the queue and clasped her fists and saluted: "What does the lord command?" ”

"Ben Hou intends to let you temporarily act as the Tao Shou General of the Pavilion," Han Zhan said to Xia Houlan, "After the high lieutenant's injury heals, I will transfer the seal ribbon to him." ”

"The last general understands!" Xia Houlan replied loudly.

Han Zhan considered that even if Gao Ran recovered from injury and returned to work, he would still be alone, and he needed to find a deputy for him. After repeated deliberations, he continued: "I will leave the two brothers Lu Kuang and Lu Xiang as deputy generals to assist the high school lieutenant in guarding the pavilion." ”

After arranging the Tao guards of the pavilion, Han Zhan looked at the civil and military officials below: "Is there anything else?" ”

Zhao Yun came out of the column and respectfully reported: "Lord Qiqi, the weather is cold today, the bedding in the barracks is too thin, and many soldiers are infected with wind chill at night. ”

"General Zilong," Hearing Zhao Yun say this, Guo Jia hurriedly asked with concern, "Have you asked Lang Zhong to treat the soldiers?" ”

"I have already asked Lang Zhong to heal them." Zhao Yun frowned and said, "Since this heavy snow came too early, we haven't had time to prepare the bedding for the soldiers for the winter, and I'm worried that many soldiers will be frostbitten tonight." ”

Han Zhan knew that in this era of lack of medical treatment, a small cold and flu could kill someone, so he hurriedly asked, "Do you have any good solutions?" ”

Regarding the issue of heating, Guo Jia was also helpless, and he said helplessly: "Jia thinks that he can only put a few more braziers in each barracks, hoping that the soldiers will not feel too cold when they sleep." ”

The suggestion to put a brazier, no one responded, such a large barracks, if a brazier was put in every room, how many braziers would be needed? How much firewood will be burned overnight? Therefore, no one responded to Guo Jia's proposal at all.

However, the speaker has no intention of listening, and the brazier that Guo Jia said made Han Zhan think of the "fire kang", which is much more economical than the fire kang, and there is no danger of carbon monoxide poisoning. Thinking of this, he said to everyone, "Do you know about the ondol? ”

"Ondol?!" Hearing what Han Zhan said, everyone looked at each other, and finally said in unison: "My subordinates don't know, and I ask the lord to teach me." ”

Although Han Zhan had never seen how to plate the fire kang, he still knew a little about the composition of the fire kang. He hurriedly drew a sketch on the paper with a brush and explained to everyone: "The kang is a bit similar to the bed we usually sleep on, about eight feet to one zhang wide, and the length can be determined by the length of the room. ”

When Xun You heard this, he couldn't help but interject and asked, "Lord, can this make the soldiers not be infected with wind chill due to the cold when they sleep?" ”

"It's not enough to just have a pit, there must be fire, otherwise how can it be called a fire kang." Han Zhan saw that everyone's attention was focused on himself, so he continued: "The kang has a stove and a smoke mouth, the stove is used to burn firewood, and when the smoke and heat from the firewood pass through the wall between the kang, the stone slab or thick wooden board on it will be heated to make the kang generate heat. Finally, the smoke of the chimney fire kang is sent out of the house through the chimney ......"

Guo Jia, Xun You and others reacted quickly, and when they heard Han Zhan say this, they immediately suddenly realized: "The fire kang that the lord came up with is really ingenious." ”

Zhao Yun hurriedly stepped forward to ask for his life: "My lord, the last general is willing to return to the barracks immediately and gather people to build this kind of fire kang developed by the lord." ”

Although Han Zhan had theoretical knowledge, he had never made a fire kang with his own hands after all, so when he saw Zhao Yun taking the initiative to ask for help, he nodded and said, "General Zilong, you immediately lead a thousand soldiers to build a fire kang in the barracks." At least 100 seats should be built before dark. ”

Don't look at Zhao Yun as an ancient person, but his IQ is no worse than that of modern people. He took the sketch of the fire kang provided by Han Zhan and instructed the soldiers to draw a gourd to build the fire kang in the vacated barracks.

The soldiers gathered outside the barracks, staring curiously at the robes that were busy in the barracks, trying to figure out what they were doing. A soldier from the crossbow battalion asked Chu Ge, who was also watching the excitement, curiously: "Chu Junhou, what are they doing?" ”

Chu Ge pinched his chin with his fingers and said thoughtfully: "I asked General Zhao, and he said that this is a kind of 'fire kang' developed by Tinghou, and the brothers sleep on it at night, even if the bedding is thin, they will not feel cold." ”

With Han Zhan's schematic diagram of the structure, the soldiers involved in the construction worked very quickly, and just by noon, hundreds of ondols that could accommodate 20 people were prepared.

If it's freezing today, I don't know how long it will take to wait until all the mud on the planks is dry. In order to test the effect of the kang as soon as possible, Zhao Yun asked people to bring firewood and burn the fire at the stove, striving to dry the mud as soon as possible.

Watching the bustle of the soldiers, they poured into their barracks to see if the kang was really warm. As the mud on the planks dried, the temperature in the room began to rise slowly, and the soldiers cheered when they noticed the change. Then the soldier who had just chatted with Chu Ge said: "My God, it is worthy of a fire kang, the whole house is warm, even if you don't cover the futon at night, I don't think you will feel cold." ”

Zhao Yun patiently waited for the mud on the wooden board of the kang to dry, and then let people spread out the straw mat, and lay down on it for a while, and after feeling the warmth of the kang for a while, he turned over and went down the pit. He called a military marquis and instructed: "While it is still early, you continue to take people to build kangs in the barracks, and be sure to build two hundred kangs before dark!" ”

Seeing that the effect of the fire kang was indeed good, the military marquis hurriedly replied loudly: "Subordinates obey orders!" ”

After Zhao Yun finished explaining his work, he immediately rode back to Taishou Mansion. Han Zhan was still discussing with Guo Jia, Huang Zhong and other civil and military personnel in the conference hall at the moment, and when he saw Zhao Yun entering the door, he hurriedly asked, "Is the fire kang plate ready?" ”

"Lord Qiqi," Zhao Yun replied with a happy face, "Now that I have set up a hundred kang kang in the camp, the last general has already experienced it himself. As long as there is firewood burning at the stove, let alone sleeping on it, even the whole house is warm. ”

After Guo Jia waited for Zhao Yun to finish speaking, he asked tentatively: "General Zilong, I don't know which is better or worse compared with the brazier?" ”

Zhao Yun grinned and said to Guo Jia: "Mr. Guo, there is not much comparison between the two. There are a few braziers in the house, which is nothing more than a few places where the braziers are placed to warm up; And this kang is as warm as spring in the whole room. ”

"Is it really that amazing?" After Guo Jia heard this, he felt that it was beyond his imagination, and he muttered: "Jia wants to experience it for himself." ”

"Mr. Guo," Zhao Yun said with a smile on his face, "When Yun left the barracks, he brought back fifty soldiers with quick hands and feet, and they all crossed the fire kang today. Just before I entered the council chamber, I sent someone to take them to the backyard and went to make a fire kang for the Lord. If Mr. Guo is interested, we can experience it after an hour. ”

"So good, so good!" After hearing this, Guo Jia nodded again and again: "Jia will definitely go and experience it for himself later." ”

An hour passed quickly, and Luo Bulai reported to Han Zhan: "Lord Qi, the soldiers brought by General Zhao have already set up the fire kang, please go and take a look." ”

When Han Zhan heard that the kang had been arranged, he stood up and said to everyone in the council hall, "Everyone, since everyone wants to know how effective this kang is, you might as well follow me to the backyard to see what is going on." ”

The group came to the backyard and followed Han Zhan into his spacious bedroom. As soon as everyone entered the door, Dian Wei said in surprise: "My God, this room is really warm enough, I don't know how many braziers are placed in it." ”

Han Zhan turned his head to look at Dian Wei and said with a smile: "Captain Dian, there is only one fire pit, not a brazier. As he spoke, he pointed his hand at the position of the new kang and said, "If it doesn't work, you can see it with your own eyes." ”

Everyone looked in the direction of Han Zhan's finger and saw a waist-high earthen kang by the wall, covered with straw mats and bedding, and there was indeed no trace of a brazier around. Dian Wei walked over in disbelief, stretched out his hand and touched the kang surface, and then exclaimed: "My God, this kang is really warm, much stronger than the brazier." ”

After Han Zhan and the others had studied the kang in turn, he asked them, "What do you think of this kang?" ”

"Amazing, simply amazing!" Everyone replied in unison.

"Lord," Guo Jia immediately made a request to Han Zhan after waiting for the room to be quiet again: "Can you also put such a kang in Jia's room?" ”

"Don't worry, Fengxiao, no matter what you want to make a fire for you." When Han Zhan said this, he swept his gaze over everyone in the room, and then said, "Where each of you lives, you will have to put this kind of fire kang on it. ”

"The lord is wise!" Hearing Han Zhan say this, everyone immediately said in unison: "Thank you Lord for your kindness!" ”
