When Chen Zhihua walked into the yard, he saw Qin Feng making coal balls in the yard with great enthusiasm.

Eunuch Le waved his shovel and mixed some loess into the carbonite at every corner of the yard. Add some water, and stirred hard to turn the carbonite into a cloud of mud. The dignified eunuch, a master of level nine, had a gangster on his body and face.

Qin Feng held the machine making a media ball, poked into the coal pile, twisted it hard a few times, then lifted it up, walked to the yard, placed the iron can below flat on the ground, grabbed the handle with four fingers, and pressed down the other small handle on the handle with two thumbs while lifting the iron can up. A cylindrical honeycomb media stood upright in the yard.

Several rows of such coal balls have been standing neatly and vertically in the yard.

"Your Majesty is so elegant!" Chen Zhihua bowed and bowed.

"It's not a good thing." Qin Feng picked up another machine and looked up at the sky. "It's rare that the sun has come out in the past two days, so I'll hurry up and make a few, and I'll make it myself and sell it myself! Try a new stove by the way."

"Your Majesty, although this charcoal can keep warm, it doesn't smell good when burned, and it can't be kept in the house for a long time. It may die if you spend a long time." Chen Zhihua said.

"Well, I already know what you said. This thing can't be placed in the soldiers' military tent. In the middle of winter, the military tent is covered tightly. There is indeed a problem with burning such a media in the big tent." Qin Feng nodded. "Is there something wrong in coming here today?"

"Yes." Chen Zhihua nodded.

"Okay, the house said." Qin Feng threw the media ball machine aside, patted the coal ash on his hand, turned around and walked towards the house, and Chen Zhihua quickly followed.

As soon as I opened the door, a heat came to my face, forming a sharp contrast with the cold outside.

Chen Zhihua looked around the room and couldn't help but exclaim, "Your Majesty, are you inside your room?"

"Did you see it?" Qin Feng smiled and walked to the corner of the house. From there, he picked up a pot of water from a stone table, poured the steaming water into the basin, pulled the facial towel, soaked it while wiping his hands and face, while looking at Chen Zhihua.

Chen Zhihua walked to the corner of the house and looked at the stone table here.

This is not a stone table, it is obviously a different coal stove.

At the bottom, the original round media stove was made into a square shape and was steadily placed on the ground. There was a table above, with thin stone slabs embedded in it. The place where the kettle was placed in the middle was lowered, slightly larger than the kettle, and it seemed that other things could be stored. The bottom of the stove was the stove. When you looked at it, you saw that the honeycomb coal inside was burning vigorously, with blue flames. On one side of the table, a tin barrel was upward from the stove, about two meters high, then turned a corner, poked out a piece, and drilled out from the wall.

Just as he reached out to touch the iron tube, Qin Feng screamed: "Be careful, this thing is very hot."

Chen Zhihua's hand was condensed in the air, only about an inch away from the iron tube, and he felt a stream of heat emitted from the iron tube.

Then reach out and press the thin stone slab in front of it, and the stone slab is also hot.

What surprised him the most was that although the room was burning coal, there was no odor at all.

Qin Feng dragged two chairs, threw them to him, and sat down by himself.

"How is it? Isn't it good?" Qin Feng smiled.

Chen Zhihua nodded repeatedly: "It's really good. It turns out that this thing can still be used like this."

"The last time something happened to the soldiers in your military tent burning coal, I asked a few craftsmen to find a solution and then made this." Qin Feng said: "The coal burning does have a very big smell, and it is also this smell that harms people. However, there is no problem to export this smell. The key is that after adding this iron tube, the whole house is warmed up. Even if the four doors are closed, there will be no harm."

"If you change this way, you will indeed turn waste into treasure. Although it is not possible to use it in the military tent, it can be used in the military camp, and ordinary families can also use it. A stove and a few coal balls can make the whole house warm. If you burn firewood, how much does it have to burn this effect!" Chen Zhihua nodded repeatedly: "I will get one too when I turn around. The key is that it is convenient and it won't make the house full of dust. Your Majesty, even if you burn the best white charcoal, there is still a lot of dust in the house."

"A small change can play a huge role. This thing is still very helpful to our Ming Dynasty. Our Ming Dynasty, coupled with the Qin land that is now occupied, has a long winter and low temperature. White charcoal is good, but this thing is expensive and many people can't afford it. Carbon is cheap, and anyone can afford it. Moreover, the more west the Qin land goes, the fewer trees are. I have asked someone to inquire these days. Not to mention white charcoal, even firewood is not cheap. Many Qin people basically rely on winter to survive. If they can't survive, they will live, and if they can't survive, they will die."

Chen Zhihua nodded.

"In fact, there are a lot of charcoal in Qin, but he always had problems burning him before, so he used very few people. With such a small improvement, this problem would be gone." Qin Feng clicked the table in front of him. "This thing can be promoted and can promote the development of an industry."

"But those who chop wood and buy wood have no work!" Chen Zhihua said with a smile.

"After all, there are a few people. If you don't do this, they can do something else. Besides, it's not easy to chop wood in such weather." Qin Feng said: "Don't leave at noon today. I'll treat you to dinner. Let's use this stove. Let's sauté mutton. Le Gong, Le Gong."

Eunuch Le walked in from outside, his face was already covered in black, "Your Majesty, the pile of coal has been made. Today, the sun will probably let them do it outside."

"Okay, let's have mutton hotpot at noon, you can arrange it." Qin Feng smiled.

"Yes, Your Majesty, I'll make arrangements now!" Eunuch Le went happily.

At this time, the water on the stove had already boiled. Qin Feng took out the tea set and prepared to make tea. Chen Zhihua quickly moved the things to his front.

"Your Majesty, I'll do it!"

Qin Feng smiled, "Okay, you are from a famous family and you are good at making these things. I can't understand the fun here. But Xi'er often forces me to do it, saying that it is to cultivate one's own character, but I still like big bowls of tea, which is refreshing."

"Everyone has their own fun." Chen Zhihua started brewing kung fu tea familiarly, "In the army, I like big bowls of tea. When I get home, I can slowly enjoy brewing kung fu tea. I make kung fu tea. The real fun is not about drinking, but about the process of brewing."

Qin Feng laughed loudly, took the small cup from Chen Zhihua, took a sip, savored it in his mouth for a moment, and then tilted his neck and drank it all, "Maybe that's the case, sometimes the process is more important than the result. Well, you said before that there were some changes ahead, what happened?"

"General Mahou is extraordinary!" Chen Zhihua handed Qin Feng another cup, picked up another cup, and slowly tasted it.

"The little monkey has made a dot and made a line?" Qin Feng was also very happy to hear this news.

"Yes, Your Majesty." After drinking the cup of tea, Chen Zhihua sat upright: "General Ma had cleared the Thunder Army cavalry around Shuanglian City, and completely cut off the grain passage from Yongdu to Shuanglian City. Now Shuanglian City can no longer support it."

"What's the reaction of the Qin army?" Qin Feng asked: "Yong sent people to open up this passage again, or was he going to give up the Double Connected City?"

"I'm afraid Yong doesn't have the courage to send out the Thunder Army again." A sarcastic smile appeared on Chen Zhihua's lips: "The entire Yongdu is only 50,000 Thunder Army. There are about 5,000 cavalry around these acropolises, accounting for one tenth. In this winter, we have been entangling with these people. The 5,000 Thunder Army has lost almost the same amount. The area of ​​the Double Defense City was originally the largest, accounting for nearly two thousand cavalry, but now there is no one. The latest spy found that the remaining Thunder Army has retreated to the Yongdu City."

"In other words, Yongdu gave up the Acropolis outside!" Qin Feng said.

"It can be said that." Chen Zhihua nodded and said, "Shuangliancheng is about to run out of food. Chen Shaowei estimated that the Qin general Lian Shaowen, who guards Shuangliancheng, might be alone."

"Lonely!" Qin Feng raised his eyebrows: "Are he going to withdraw from Yongdu City? This is a death sentence."

"It's true!" Chen Zhihua said: "Lian Shaowen is a good general. Shuanglian City is more than fifty miles away from Yongdu, and now these fifty miles are full of our cavalry, so he has no chance at all. But they are only ten miles away from Chen Shaowei's camp."

"Does Lian Shaowen want to attack Chen Shaowei's camp? Then rob the supplies from Chen Shaowei's camp?" Qin Feng felt a little incredible.

"Harding is a dead end, and withdrawing Yongdu is a dead end. Although it is difficult to attack Chen Shaowei's camp, there is not a chance." Chen Zhihua smiled and said, "It failed, but once it dies, but if it succeeds, they can hold on for a while and at the same time increase the morale of the Qin army. Even Shaowen drove all the relatives in the city when the food and food supply in Shuanglian City were in a hurry. He can really do such a thing."

"Is this Chen Shaowei's judgment?" Qin Feng asked.

"Yes, so Chen Shaowei is ready to wait for Lian Shaowen to go to the trap. At the same time, he also sent someone to send a letter asking me to order Mahou's cavalry and the cavalry of Zhuifeng Battalion to help the New Third Battalion divide the connection between the other acropolis and the Double-Alliance City. Chen Shaowei estimated that the other acropolis might support the Double-Alliance City. Because everyone knows the role of the Double-Alliance City on the entire Acropolis defense system."

"Well, it's a bit interesting." Qin Feng smiled and said, "I have to go and see such a lively atmosphere. If I can clean up all the acropolis outside Yongdu this winter, I will save a lot of trouble next year."

"This winter, if we can push the Bingfeng to Yongdu for dozens of miles, I believe Yong will be even more nervous." Chen Zhihua added.
