Soon, coal became quietly popular in the three villages of Longquan, Ankang and Wuwei, and it happened to be matched with the iron pot stove and the fire kang, which officially ended the history of burning firewood.

You should know that in this era, picking up firewood is also a big job at home and is a waste of manpower.

The blacksmith shop and woodworking workshop also worked overtime to make bellows and supporting facilities. Of course, Li Feng didn't have to worry about these. He led the Taoist team and had already begun to study the methods of coking.

In addition, under the guidance of Shan Zhongjun, several brick kilns have been excavated. There were two small kilns in the original Zhangjiazhuang, and Li Feng was preparing to do big things. This was not enough, so he had to continue building the kiln.

In this era, firewood and charcoal were used to make bricks and tiles, so the cost was very high.

Haven’t you seen that when Emperor Wen of Sui built Daxing City, the city walls were built with rammed earth? It’s because the cost of burning bricks was high.

But if it is changed to burning coal, the cost will be greatly reduced. It is precisely because of this that in the later years, bricks and stones were used to build city walls in the Ming Dynasty.

If a modern coking plant was built, Li Feng would definitely not be able to solve the existing conditions. However, later, the coking was able to be done in the Song, Yuan, Ming and Qing dynasties, and it would be impossible for him to be done in his era.

Ask Xiao Ai to help collect relevant information, Xiao Ai also teased her brother: How backward are you going? Take a photo and take a look.

I took a lot of photos, but I can't show you now.

We organized manpower and built several coke ovens. Considering that this thing is more polluted, it is better to be far away from Wuwei Village. Moreover, we must also take into account the wind direction to avoid blowing smoke and dust to the village.

It is said to be a coking oven, but it is actually built with burn-resistant clay. A large steamed bun-shaped earth kiln has a height of about two meters. After filling with stinky coal, ignite the surrounding ignition ports, and the coal inside will burn. The burned waste gas is discharged from the uppermost vent hole.

Usually, it takes five or seven or eight days to burn until the ventilation holes stop breathing, and then slowly pour water into the furnace. After condensed, pieces of coke condensed.

This method of coking is relatively bad, and some of the coal is burned into coal ash, and the yield rate is not high.

Fortunately, coal doesn’t cost money, so it only costs some labor, so it can still be afforded.

After the coke oven was ignited, during the few days of burning the furnace, Li Feng finally made time to go to Luoyang City to meet with the medical team. Calculate the time, construction is about to start in the new Luoyang City. The time for the medical team inspection is coming soon, and Li Feng also feels nervous before the war comes.

Those who accompanied him were Grandma and Xiao Nunu, Yasha and Huma. In addition, Li Qianjun and Li Polu brought ten female soldiers as guards.

Li Feng originally said it was not needed, and the current public security is still good. But Li Bubai was worried. After all, there was a lesson in the past, and Li Feng couldn't help but smear others' good intentions.

As the crowd entered the ancient Luoyang City, it was obvious that the number of migrant population in the city was increasing, brewing a kind of tension and busyness before a major project.

Zhang Sanlang led the way in front and led them to the new location of the clinic in the east of the city. The bearded guest was indeed a big deal. It is several times wider than the medical college in Daxingcheng. It is said that it is also the ancestral property of the Zhang family.

Anyway, after the new city is built, it will be demolished here and there will be no loss of money.

Yes, the largest demolition was carried out by Emperor Yang of Sui. It was similar to later generations. Is it demolished? There must be many nouveau riche.

The clinic is facing the street, and the Red Ten Medical Team has been hung. Tanghe is sitting in front of the hall and behind the yard. There are actually more than a dozen patients queuing up for treatment.

There are more doctors who see a doctor than a patient, and they all stand behind Tang He. Wait for Tang He to see it first, then these students get started, and finally, they will confirm with Tang He.

Although the patient feels a little troublesome, fortunately, he does not need medical treatment fees and only charges for decoctions, so he endured it: it doesn’t cost money, don’t you ask someone to touch his wrist a few more times!

"Master Li!" Seeing Li Feng, the students greeted him affectionately.

Li Feng nodded to them, then said "not distracted", and went to the backyard. The several ox carts he brought had already started unloading coal into the corner of the yard, as well as two large bellows and related supporting facilities.

The craftsmen have long been skilled in the work and started to install. After they taught Li Kutao and others to use it, they made these cooks feel happy: cooking in the future will no longer be difficult!

After Sun Simiao and Zhen Quan finished class, Li Feng went to see the ceremony. The three of them sat down. Just as they were about to speak, they saw Master Yin Mo and Yin walking in with a stack of paper, first saluting to the three teachers, and then reported to Li Feng alone: ​​"Master Li, this is a list of purchasing medicinal materials. I will calculate it. It requires more than 120 guan. This money--"

OK, you have to pay the bill when you come, right? Li Feng didn't feel the corners of his mouth, which made the others in the room a little embarrassed. Zhen Quan immediately gave him a high hat: "Who said Dalang, you are skilled in medical skills and good at economics. Those who are capable work more, and those who are capable work more."

Li Feng spread his hands: "I'm empty-handed now-"

The other people also knew that they had to place more than a thousand people, not only eat, drink, defecate, but also prepare for farming and production, but they did not spend money like running water. It would be good if they didn’t drink the northwest wind now.

It’s really hard to be loyal - King Sun Yao also looked at his disciples and felt a little distressed.

In the past two months, Li Feng has been relying on the dividends from Pei Xuanji and Xue Shi to support him. It will be great if he can survive this period.

However, he was not in a hurry: "When he came, he heard from his grandmother that there was a branch of my Li family in Luoyang. He once borrowed hundreds of stagnant of money from my grandfather to do business. After a while, the grandmother took me to visit and got the money back."

"We are the ones who have made things difficult for Master Li." Master Yin now completely regards Li Feng as his idol. He has good poetry and prose and excellent medical skills. What he admires the most is that Master Li has been spending money in medical schools in the past few months.

He is responsible for the college accounts and knows deeply that putting this money in a well-off home is enough to enjoy a lifetime.

Li Feng waved his hand: "Why do you have to blame yourself? You have done a good job. The biggest test is coming. Let me tell you to prepare for hard work."

After a brief arrangement, I should have gone to see Master Xue first. However, after this old man took office, he went to the county and county to inspect the academic affairs, not in Luoyang City. So Li Feng helped the grandma and led the little Nunu and the family of three to visit his relatives under the guidance of Zhang Sanlang.

Just visiting relatives, there is no need to take Li Qianjun and the others with you.

Zhang Sanlang was familiar with the land, and soon led Li Feng's family to the most prosperous area in Luoyang City, pointing to a large shop in front of him and said, "Dalang, this Li silk and satin shop is the largest in Luoyang, and it is not an exaggeration to say that he can make money every day. Unexpectedly, he was the same clan as Dalang. I heard that they are from the Li family of Zhao County, and I think Dalang is also from the Li family of Zhao County."

Zhang Sanlang was originally the family of the bearded guest, but now he follows Li Feng, so he naturally also calls him Dalang.

The Li family of Zhaojun is one of the most famous families in the world. At present, the most famous ones are the five surnames and seven sects, among which there are two surnames and two surnames of Cui and Li.

All the surnames in the world are proud of their origins from the five surnames and seven sects. Even in the Tang Dynasty, the imperial family’s princess mainly married the children of the Cui family, and they were not happy and refused directly. Just say it’s awesome or not?

Li Feng, a later generation, naturally didn't care about these backgrounds. So he helped his grandmother into the store and looked around. Sure enough, he did a big business.

The store displays a variety of fabrics such as silk, brown, cloth, Burmese, gauze, silk, silk, brocade, and silk, and colorful. The brocade also has turtle back patterns, polygonal patterns, ten thousand characters, double short patterns, tangled branches, etc. The flowers are clustered with beautiful flowers and can be called the pinnacle of ancient handicrafts.

Seeing an old shopkeeper in the store who was resting with his eyes closed, Li Feng stepped forward and explained his purpose, and finally said, "Don't bother the shopkeeper and lead us to the master's house."

The old shopkeeper lifted his eyelids up, his eyes full of contempt: "The master doesn't need to see you. The old man has already given instructions. Your team has been fired from the Li family of Zhao County. If someone comes to be a debt collector, just beat them out - come here, invite these distinguished guests out!"
