In the twinkling of an eye, the temperature in the North has reached the point of dripping water into ice.

But the freezing of the Yellow River has greatly facilitated the army to cross the river eastward.

At the moment, Qin Huan was busy resettling refugees in Nanyang. Carts of grain were transported from Xiangyang to supply the rations of millions of people in Nanyang.

With the advent of winter, people from Henan and runing continue to come to Nanyang with their families. By December, the number reached as many as one million.

Nanyang has no more land. Except some of these people were sent to Xiangyang, most of them were sent to the mine.

Young men and women dig mines. When they are old, they do some easy work. Girls of school age are sent to ladies' College, and boys are apprentices in factories and kilns.

At the foot of a mountain in the west of Nanzhao County, looking around, there are thousands of earth kilns rising from the ground. At the moment, there are rolling black smoke. Tens of thousands of people shuttle among them. The scene is very spectacular. More people are mining in the mountain, and there will be explosions from time to time.

Some of these kilns burn bricks and tiles, some burn glass and process salt, but more are burning cement.

Qin Huan didn't expect that the Ministry of heavenly works had burned cement and glass in just over a month.

Although the cement was different from the previous life, it was much better than cutting the wall with lime after solidification, so Qin Huan immediately planned to let them continue to make drums while mass production.

A full 500 earth kilns were built at one go to burn cement.

The glass also could not be compared with the previous life. It was dark red. To be exact, it should be called colored glass. However, as long as it continued, Qin Huan believed that it should not be far from transparent, so he only built ten kilns, which were mainly used for research, and used waste to make some lampshades and so on.

To Qin Huan's great joy, there were a lot of lime and clay near the salt mine. There was also a lot of quartz sand in the river at the foot of the mountain, so he simply built all the kilns at the foot of the mountain.

The only regret is that coal will be transported from Xichuan.

"Husband..."

"Girl, why are you here?" Qin Huan was surprised to see that it was Hong Ying escorting the team.

"They asked me to come and let me catch you back for the new year." After jumping off the horse, the red warbler jumped into Qin Yu's arms and said with a smile.

"Hehe, I think you miss me!" Qin Huan smiled and quietly grabbed her chest.

Where still don't understand, is Zhang Yan they miss themselves, but they are embarrassed to take the initiative to find themselves, so they encourage this girl to come over.

In fact, he depends on Nanyang. In addition to developing military industry and heavy industry, he also wants to avoid the cannibal female tigers in his family.

After all, he is still young now. It's terrible for him to sing every day. He doesn't want to die to enjoy sitting in the world after he has won the world in the future.

He can still control in front of other women. Even Mrs. Li can sleep in her arms until dawn.

But only in front of Zhang Yan, she couldn't help it. The woman was typically not charming and charming. Once she slept, she had to touch rain and dew, so she couldn't afford to provoke her, so she had to hide.

The red warbler immediately blushed with his pinched cheeks. Seeing that there were people everywhere nearby, he hurriedly pushed him away and asked:

"Xianggong, the eight kings, Chuang Wang and Cao Cao all call Wang Jianguo. The brothers in all towns can't help it. When do we have to wait?"

"What's the hurry? I have my own plan. In addition to losing and winning wars, an army should also be calm! " Qin Huan waved his hand.

"But now is not a rare opportunity. With our current strength, we can sweep the whole Huguang, or go north and win the whole Henan." The red warbler never dies.

"Yes, we can take it, but after taking Huguang, we don't have so many people to manage. After taking Henan, we don't have so much food to feed the people for the time being. Our food can just last until the summer harvest in May next year, so we might as well let them toss first." Qin Huan explained patiently.

"Then the troops will be divided into two routes. I will attack Henan in the north and save those ladies and girls. You will sweep across Huguang in the South and collect food from your family. In this way, there is no shortage of managers and food?"

The red warbler pinched her fist. Obviously, there has been no war since she captured Zaoyang. She was suffocated.

"Ha ha, it's really a three-day leave. Look at it with new eyes!"

Qin Huan was very surprised at first, and then he laughed because the girl was the same as he thought.

After Lu Xiangsheng went south, the reason why he didn't take runing house with his hand was that he wanted Niu Er and Cao Cao to wreak havoc first, kill all the big families, and then be the Savior himself.

"Do you agree?"

Hong Ying was very happy. She just said it casually. Unexpectedly, Qin Huan reacted so much.

"Even if you agree, it's not now, but next year."

Qin Huan didn't have a good way to see her like this.

First, with the improvement of technology, the output of the arsenal has increased several times. He plans to change and reorganize before he starts.

Second, there is too much pressure from the north and the south to attack at the same time, so the garrison in each county and the militia in each village should be improved, and the knives and guns eliminated by the regular army are just equipped for them.

After all, most of the knives and guns in the hands of the Chinese army are seriously chipped and uneven in grinding.

Seeing him say so, the red warbler also knew that this year was over. Although she was disappointed, she was not tangled. Then she looked at the rows of earth kilns in the distance and exclaimed, "so many kilns?"

"Hehe, let's go. I'll take you there to open your eyes."

Qin Huan said and took her hand and walked towards the earth kiln.

"Xianggong, can salt really burn out of the stone?"

The red warbler looked at the baskets of stones broken by the young man with a sledgehammer, and then put them into the pool. He couldn't help but be surprised.

"You can burn it, but it's too troublesome." Qin Huan smiled bitterly and explained to her the process of salt processing.

Because the salt mine is on the hillside rather than underground, it is impossible to dig wells to get brine like Sichuan well salt.

Instead, it can only be mined manually, and then the salt ore is transported down the mountain to be crushed and soaked in the pool to dissolve and precipitate.

Then scoop out the water, filter it twice, pour it into a big pot and cook it, so as to get some yellowing salt.

Fortunately, the content of this salt mine is not low, reaching 30%.

Now there are 20000 people making salt alone, 5000 mining, 5000 transportation, 5000 crushing, and finally 5000 filtering and cooking.

There is no way. There is no water on the mountain. We can only get cooking and filtration at the foot of the mountain. The mountain is steep and must be carried on our shoulders.

20000 people can produce about 50000 kilograms of yellowing salt every day. Although this kind of salt is bitter, it can't eat dead people. It is much better than the inferior salt of this era. At least there is no soil and sand in it.

After dissolving the yellowing salt, filtering and cooking again, you can basically catch up with the green salt of this era, and the taste is quite good.

As for the snow-white salt, it must be dissolved and filtered again, and it can't be boiled in the end. It's the most troublesome to use the sun.

Therefore, he plans to divide the salt bar into three grades in the future. Ordinary yellowing salt bar is produced in large quantities and the price is cheap. The purchase object is mainly ordinary people.

The second is the secondary processing of green salt, which is purchased by large families. It should sell at least two liang of silver a kilo.

As for the final refined salt, only a small part will be produced, and the lowest price will be ten Liang silver a catty.

These three kinds of salt will be exclusively operated by commercial firms. There is no restriction on the purchase of green salt and refined salt, but the purchase of yellowing salt should be restricted, otherwise it will definitely be snapped up by foreign merchants.
