Iron was controlled by the imperial court, and the next best thing to do was to find a coppersmith to see if he could get a copper furnace out. Su Ren designed the appearance and asked Liu Gao to find a craftsman to make it. Copper is softer than iron, so it naturally takes less time to build. Three days later, the world's first copper furnace appeared in Su's house, the round furnace body, three feet slightly tilted outward, in order to smoke, a long copper pipe, one end connected to the copper furnace, one end stretched out to the outside of the house.

The fire power of charcoal is really not good, so it is simply lit in the copper furnace. The thick firewood burned so vigorously that soon the whole stove burned red, and the temperature in the room rose. Finally, I don't have to cry anymore, and I finally found some feeling of a heating room in the future.

Su Ren threw down the quilt draped on his body and circled the copper furnace twice: "Why do you feel that it is about to burn, is the wall of the furnace too thin?" ”

Liu Gao nodded: "It should be, the craftsman probably didn't understand that Brother Ren wanted to use this thing to burn the fire." ”

"Then start over and make it thicker!"

During the day, he was busy working on the construction site, and at night he came back to see the craftsmen building the copper furnace. The first one was burned because the furnace wall was too thin, and it took three days to burn a hole, but fortunately it was firewood, if coal was used, there would be gas poisoning, and Su Ren would confess. The second stove took five days, and finally got it out, and it was surprisingly heavy. According to Liu Gao, almost 300 catties of copper were used, and Su Ren touched it, and the furnace wall was a palm-thick.

The weight is heavy, and the victory is strong. Copper has good conductivity, and although it doesn't heat up as quickly as the first furnace, it's still good to use. With a stroke of his pen, Su Ren allocated 5,000 catties of copper to the craftsman, all of which were used to make furnaces. Because of the stove, Su Ren's house has become everyone's favorite place, and there are constant people here from morning to night every day, even Twelve Niang and Thirteen Niang holding their children and pulling Dong Qian and Leng Yue in, who doesn't want to live in a warm house without smoke?

Twenty stoves were built in one go, except for the ones used at home, there were still a few left, and they were given to Cui Chengru, Dou Ying, and Dou Fu, how to deal with the rest? Sell it, right? Rich people take a look at themselves and go back to build them, and it's useless to keep them if they don't sell them. After thinking about it for a long time, I decided that it was a good choice to use it as a gift for the emperor while this thing was not yet popular in Chang'an.

When Su Ren came, Liu Che watched the recital in the Xuan room with snot and tears in his eyes. It was too cold outside to open the windows, and the smoke from the brazier in the house had nowhere to go, but to accumulate more and more. The houses of Dahan are generally low, which increases the deposition of smoke gas. He coughed violently a few times, and the smell of charcoal filled his nostrils and mouth. The chamberlain hurriedly brought a silk handkerchief soaked in water to wipe the emperor's face.

"Your Majesty, Yilang Su Ren asked to see him, saying that there is a treasure for His Majesty!"

"Treasures? What treasure? Can you keep me away from this annoying smoke? ”

The chamberlain hurriedly said, "Your Majesty, Su Yilang said that he came for this matter." ”

"Oh? He'll pick the right time to let him in, and I'll see how he gets rid of this annoying smoke! ”

Su Ren covered his mouth and nose as soon as he entered the door, and the palace maids who commanded the army and seized the lord hurriedly opened the doors and windows. The cold wind blew in one by one, and the frozen Liu Che shivered, and the chamberlain hurriedly found a thick cloak for the emperor to put on. Wrapped in clothes, Liu Che said angrily: "You are the only one who dares to be presumptuous here, what do you want to do?" Frozen to death? ”

Su Ren sighed: "Your Majesty can stay in this kind of place for a day, I really admire Your Majesty's endurance!" ”

"Could it be that you really have a way?"

Su Ren smiled and nodded: "The minister is here for this matter, Your Majesty will understand after a while!" ”

With a wave of his hand, several palace people carried the things that Su Ren brought into the palace and placed them in the main hall. Su Ren pointed to the copper furnace and said: "This is called a stove, it was made by Weichen a few days ago, lighting a fire in it can not only warm the house, but also remove the smoke!" ”

Liu Che circled around the copper furnace twice with interest, and looked at Su Ren with a puzzled expression. Su Ren didn't explain either, and commanded the palace people to start building. A huge copper furnace was placed in the center of the main hall, and long copper pipes protruded from one corner of the window, one after the other. More than a dozen palace people came in with wood, lit a fire in the copper furnace, put the wood in, and covered it with a copper cover.

During the whole process, Liu Che didn't say a word, shrunk on the couch and watched Su Ren command the palace people to be busy. When the smoke in the house was exhausted, Su Ren asked the palace people to close the doors and windows, and the fire in the copper furnace was burning. As the copper furnace turned red, the temperature in the room rose little by little.

Liu Che looked at the copper furnace in front of him in surprise, and then looked at Su Ren: "How did you come up with it?" ”

Su Ren said: "Your Majesty worries about the people of the world every day, and I worry about how to live comfortably every day. ”

Throwing away the cloak on his body, looking at the room without smoke, Liu Che laughed: "Good things, definitely good things, are there any more?" Make me a few more. ”

"Yes, yes, but ...... the cost?"

"I'll give you money!"

"That's it!" Su Ren nodded again and again: "There are four or five, I brought them all, so I will go to Changle Palace, Yongshou Palace, and Lanlin Garden, let people set up, let the Empress Dowager and the Empress Dowager know Your Majesty's filial piety, and let Mrs. Wei know Your Majesty's concern for her!" ”

Liu Che laughed: "I finally know why you can become the biggest businessman in Shu County, just because of your cleverness, I don't want Chengdu to be difficult!" ”

All day, Su Ren was busy in the palace. The Empress Dowager's Changle Palace, the Empress Dowager's Yongshou Palace, Wei Zifu's Lanlin Garden, and even the Queen's Jiaofang Palace, ran all over again. set up the copper furnace over and over again, and instructed the palace people and palace maids over and over again how to take care of them. When I returned to Jianzhang Palace, I didn't even have time to eat lunch.

Constantly receiving praise from several elders and thanks from his wife, Liu Che was in a good mood, and without saying a word, he gave Su Ren a banquet, which was regarded as a thank you for the good things Su Ren gave him. The palace rice is indeed exquisite and delicious, a large plate of mutton, a large bowl of soup cakes, Su Ren ate until he was full.

Liu Che shook his head and smiled bitterly: "You haven't eaten for a few days?" ”

Su Ren swallowed the last bite: "It's still the food in the palace that is delicious, no wonder everyone in the world wants to eat under His Majesty!" ”

"Delicious, isn't it? That can't be eaten in vain, this meal will be on top of those stoves! ”

"Ahh More than a thousand catties of copper for a meal? Is this too expensive? ”

"Then you spit it out!"

Su Ren was speechless and looked at Liu Che: "Okay, I admit it, next time if there is anything good, collect the money first and then talk about anything else." ”

"Hahaha...... what other good things to take out? Otherwise, I will cure you of the crime of deceit!" ”

"Poof!" The sip of soup I just drank spurted out. Su Ren wiped his mouth and looked at Liu Che: "Your Majesty, let's not play like this!" If that's the case, next time if there is really something good, I really don't dare to bring it to the palace. ”

Liu Che's tears of laughter fell, no one had spoken to him like this for a long time. He is the emperor of everyone in the world, and everyone who sees him is cautious and cautious, and he doesn't say a word if he can. But this Su Ren and him don't seem to have any identity barriers, how nice it sounds to say first, at least a balanced attitude, which makes Liu Che very relaxed and enjoys this feeling.

Liu Che felt that he and Su Ren were not emperors and courtiers, but more like friends who had not been masked for a long time. I feel that this Su Ren is different from everyone else, whether he is speaking or doing things, he stands at a higher angle than others, farther than others, and has a feeling of looking down on the world. This world also includes him Liu Che.

Liu Che thought for a while and said, "No need for next time, just this time, I ask you, how did you use to collapse the horizontal door?" Without waiting for Su Ren to answer, Liu Che continued: "Don't say anything about heavenly punishment, I heard that when I was in Shu County, there were a few similar things, although it was not as big as the Hengmen matter, but it was also not small, how could the heavenly punishment be punished on the people who were not good for you?" ”

"Ji Huang got some things back from a merchant in Shu County, I sent someone to try it, it was very powerful, according to what the merchant said, you just used this thing to do what kind of heavenly punishment, I let people see it, no one knows how to get it, today is just right, tell your secret, I can't eat this meal in vain!"

Finally talked about this matter, when he was still in Shu County, Su Ren saw that the angel Ji Di was living in Zhuo Wang Sun's house and did not leave, so he knew that there was a problem. According to the news that Zhuo Wangsun had taken several jars of gunpowder from the Yandi Copper Mine before it was bombed. As soon as Liu Che said this today, the whole thing was completely connected.

Su Ren hurriedly put away his smile and looked left and right. Liu Che understood, drove out all the chamberlains, palace people, and palace maids, and ordered the guards outside the door to kill anyone within ten zhang of the house.

Everything was done, Su Ren took a deep breath: "Today I will tell Your Majesty that this thing is called gunpowder, which is the secret of my master's sect, how powerful Your Majesty has seen it, and the minister only said that if there are 100,000 catties of gunpowder, Chang'an City can be razed to the ground!" ”

"Razed to the ground? Is it really that powerful? ”

Su Ren nodded: "The minister has a secret workshop in Yelang, and he is stepping up his research, the reason why he didn't mention it to His Majesty is that this thing is not very mature, and second, our Han needs this thing, Your Majesty can think about it, when the Han army and the Xiongnu go to war, what will be the effect of this thing?" No matter how powerful the Hun iron cavalry is, in front of gunpowder, they are just a pile of minced meat! ”

Liu Che was so excited by Su Ren's words that his face turned red.

Su Ren continued: "Your Majesty mentioned it today, the minister is not hiding it, the minister proposes to secretly move the minister's workshop in Yelang back to Chang'an, Your Majesty will send a reliable person to be responsible for this matter, we hoard a lot, and when the war with the Xiongnu starts, let the Xiongnu know how powerful we are!" ”

Liu Che's eyes shot out, although he didn't understand what the gunpowder Su Ren was talking about, he still knew the power. moved his body, sat cross-legged beside Su Ren, and nodded again and again. At this time, Liu Che and Su Ren were two bear children, and they were still the kind of bear children who were ready to do bad things. The two of them got together, sometimes muttering, sometimes laughing. You say a word and I say a word about their vision for the future.

After a glass of wine, Su Ren drank too much and put his arm around Liu Che's shoulder: "You are a good emperor, in the eyes of future generations, you can mention it alongside Qin Shi Huang, who unified the six countries, since I can't go back, then help you, let's make this Han last forever!" ”

Liu Che also drank a lot, nodded and smirked: "Hahaha, okay, a word is a certainty, when we are old, we will walk all over the world together!" ”
