The price of coal was set so low, which surprised Su Shuang and Zhang Yi. Ten dollars a catty, this price is almost equivalent to the price of firewood. Moreover, coal is comparable to charcoal, or even better than charcoal, but its price is so low, it is incredible.

Setting the price of coal relatively low is not Lu Bu's reckless behavior. Lu Bu also knew that coal was mined on the ground, which was extremely difficult. Even in the later generations, there are many mining accidents, and it is naturally not easy to mine under the current conditions. But Lu Bu personally went to find out that most of the coal mined at this time was open-pit coal mine, and it was not difficult to mine. Bingzhou is a famous coal producing area in later generations, and there are many open-pit coal mines. If these coal resources are extracted, there should not be much problem with supply.

In this era, the utilization rate of coal is far from being comparable with the utilization rate of modern industry in later generations. Modern coal is more used for heating and iron smelting. However, judging from the records of ancient books, before the Song Dynasty, there were not many coal smelting iron? Why? It's still a matter of craftsmanship. Before the Song Dynasty, although coal could be used as fuel for ironmaking and steelmaking, there were many harmful substances when coal was burned, and the quality of steel would be affected when it was burned into molten iron. In the Song Dynasty, coal was truly developed and utilized, and it officially had the name of coal. The reason for this is that the coal mining project in the Song Dynasty has progressed a lot, and the coal block has been improved into coke, which is purified on the basis of the coal block, in the blast furnace, whether as a fuel, a raw material, or in terms of heating performance, is much higher than coal.

And the state is short of money, and even more so of people.

With coal, more people can face the cold and have hope of survival. The pricing is extremely low, and it is as affordable as possible for most people.

“…… The price of coal is extremely low......"

Su Shuang sighed, "It's just that it really burns longer than charcoal?" If it burns like charcoal for a long time, I think it will make a lot of profit by selling it......"

"If Zhong Fei doesn't believe it, I still have some coal here, you can sell some first and see how it works......"

Lu Bu said.

"Yes."

Su Shuang nodded.

Looking at the somewhat bright eyes of Su Shuang and Zhang Yi, Lu Bu knew that if he gave them coal, the price might not be so cheap. But Lu Bu is not worried, this coal is still only mined by him and the state. Maybe there are still some places in the land of Sanfu, but it will definitely not be like Lu Bu, who dispatched a lot of manpower and material resources to mine! Nor will there be as many open-pit coal mines as there are in the state. Even if Su Shuang and the others sell high, it will be a big deal to discuss profits with Su Shuang and Zhang Yi in the future.

Everyone has a selfish side.

Lu Bu is not a saint, he wants the poor people in the world to no longer suffer from evil and cold, so that those who work hard can survive in this troubled world. But this ideal is too far away! Now he is just a state pastor! Just manage his merger with the state, and he doesn't want to manage people in other places, and he can't manage them.

Su Shuang and Zhang Yi left satisfied.

I don't know why, when they came, they were still two horse dealers, but when they left, Lu Bu felt that neither of them seemed to care about the horses. After learning about coal, the two may be thinking about how to make a greater fortune.

Because it wasn't just coal, Lu Bu also talked to them about paper. Lu Bu's preparation for improving papermaking is also in the plan, since Cai Lun improved papermaking, the production of paper is mostly based on hemp and mulberry. After Cai Lun, Zuo Bo paper in the late Han Dynasty also improved it a little more. But Lu Bu's improvement this time will be based on bamboo raw materials, and there are many places where bamboo is produced in Hanoi. Because the climate of the Han Dynasty was relatively warm, the north also produced a large number of bamboo. The new and improved papermaking technology is bound to cause a new revolution.

The sky was full of snow, and it poured for a few days. The snow on the ground is not shallow, and it can bury no one's shoes. It was supposed to be extremely cold weather, but Lu Bu was only wearing a thin single coat, and he was enthusiastic to roll up the snow on the ground, and there was a half-human-sized snow mass rolling in the snow. Behind Lu Bu, Lu Lingqi cheered and jumped with joy, following Lu Bu's steps, "Building a snowman......

In a quarter of an hour, the body of a snowman the size of a man was almost formed. Lu Lingqi's little hands, which were red from the cold, also repaired the shape of the snowman, and made the mouth and nostrils out of the snowman.

"It's almost ......"

Lu Lingqi stared at the lifelike snowman, and always felt that something was missing, "eyes...... Snowmen don't have eyes...... Waiting for ......"

Like a gust of wind, Lu Lingqi ran back to the house.

Looking at Lu Lingqi who was running, Lu Bu showed a smile. Concentrate on repairing the snowman, after the exercise just now, in this cold weather, Lu Bu actually felt a little hot. From the nostrils, constantly exhaling white breath,

"Daddy, Daddy......"

Lu Lingqi ran back, grabbed the sleek pebbles in her small hands, and inlaid them on the nose of the snowman, like two bright eyes.

“…… The snowman is good......"

Lu Bu didn't expect that Lu Lingqi actually had two smooth stones picked up from the river, which were inlaid on the snowman's body, which was really like the finishing touch, making the entire snowman feel alive.

"Where's the ear..."

Lu Lingqi grabbed a handful of snow and pressed it on the snowman's head, making it into an ear shape. Lu Bu put her hand on her big hand, a little cold, "Remember to bake the stove when you go back...... Look at your little hands, how cold they have become......"

"Lingqi is not cold......"

Lu Lingqi sniffled and said with a smile.

Looking at Lu Lingqi, Lu Bu also smiled and touched her head, "Go, go back......"

"Where's the snowman......"

"The snowman is here......"

Lu Bu said, "...... Didn't you always give a name to the snowman in previous years, why didn't you choose it this year? ”

"Lingqi has grown up......"

Lu Lingqi's eyes were a little complicated, "After this year, Lingqi will be thirteen......

Stomp and tread.

Just as Lu Bu was about to speak again, not far away, a horse flew over.

"Feng Xian, you can go......"

Someone dismounted and brought a white horse over, it was Zhang Liao.

"Hmmm......"

Lu Bu replied lightly, turned his head to look at Lu Lingqi, "Let's go in and bake the fire......

"Oh."

Lu Lingqi's eyes darkened.

The time spent together is always short. Lu Bu has a lot of things to do every day, and it is very good to be able to take some time to play with Lu Lingqi.

Lu Bu also entered the mansion and changed his clothes.

After a while, Lu Bu walked out, and Dian Wei brought the red rabbit for Lu Bu.

Stroking Chitu's sideburns, Lu Bu felt that Chitu was a little restless today, and exhaled a wave of heat in his nostrils.
