In winter, the frozen soil is not easy to dig, and it took five days to dig through the shafts and horizontal shafts.

It took a month for the masons to build a layer of bricks on the shaft.

It took ten blacksmiths more than ten days to fail several times to pour the bottom bar, and the Tang Dynasty, which did not have an electric welding machine, could only rely on pouring to make large iron parts.

Ten men shouted trumpets and lowered the diameter bar to the bottom of the kiln with hemp rope.

"First lay a two-meter layer of firewood, sprinkle it with oil, then lay a layer of coal, then a layer of stones, a layer of wet coal, a layer of stones, and then a layer of wet coal. When this is superimposed on the top layer of the shaft, it is ready to ignite. Leng Feng explained to the county order.

The county commander of Sanshankou County, Luo Minsheng, has been busy these days. At first, I heard that there were many people with extraordinary manners in Chang'an City, and I heard that a cement workshop was going to be established. This is a very good thing, a workshop built under his rule can make money for his people, and he, as the prefectural governor, must thank the owner of the workshop.

But before he could leave, the Divine Decree arrived!

As a small county magistrate, Luo Minsheng never thought that he would have such an honor as receiving the holy decree. After he had prepared the incense case and bowed to the ground, the eunuch who had delivered the decree spoke:

"The emperor's edict said: Today-Tianxialou will build a fire kiln in Sanshankou County, which is beneficial to the people, and ordered Sanshankou County to order Luo Minsheng to fully cooperate, and he admires this."

Luo Minsheng was dumbfounded, this workshop owner is really fierce! There was a holy decree asking the magistrate to cooperate with it.

Shocked to shocked, Luo Minsheng received the decree and offered the holy decree with incense, and then began to run for the kiln. He did all the chores of finding migrant workers, blacksmiths, and masons.

Today, the kiln was completed, and as a prefectural magistrate, he was specially invited to participate in the ignition ceremony of the kiln.

Luo Minsheng, who was holding a torch, crossed the horizontal road, tremblingly put the torch on the fine firewood on the railing.

The firewood poured with fire oil suddenly burned!

Luo Minsheng hurriedly rushed out of the crossway, looking at Leng Feng and waiting to listen to the next work.

"When the white stone is burned by the fire to become 'cooked', the cooked white stone is crushed into powder with a stone mill and mixed with sand powder, and the ratio is ......"

Luo Minsheng immediately stopped Leng Feng's continued behavior: "Dongjia, this is the formula!" You can't pass it on! ”

Leng Feng was stunned for a moment, and then remembered that it was now the ancient time when the law was not passed on to the six ears, and many formulas and everything could only be known by the disciple's son.

However, for the sake of some black-hearted businessmen blindly imitated and harmed people's lives. Leng Feng also gave up the idea of spreading the word.

Although Leng Feng's lime kiln is also the most primitive one, he equipped the workers with wet masks and other labor tools, just for fear that the workers would get sick. The white stone used in the lime kiln was not mined, but collected by people in the river.

"Okay, I won't talk about it, the manager will instruct the migrant workers to work, as the county order, you need to come here once a month, responsible for supervising the distribution of migrant workers' wages and the output of the workshop. The output of the workshop needs to be submitted to the Ministry of Civil Affairs as a basis for collecting taxes. ”

Luo Minsheng nodded, with his supervision, there would definitely be no deduction of money and food from migrant workers.

The steward of the cement workshop was asked by Li Tai and his father, and he was not a eunuch.

Looking at the steward who skillfully assigned the jobs of migrant workers immediately after knowing the formula, Leng Feng deeply realized the terrible number of talents in Li Shimin's hands.

The first bag of cement was sent to the palace by the steward as soon as possible.

The emperor attached great importance to this material that could strengthen the city pass......

Looking at the big pit full of human and animal feces and weeds, Li Chengqian almost vomited: "Master, is what you said true?" Can this thing increase food production? ”

The Datang people believe that plant ash is the best fertilizer, and the smoke of burning straw will not stop every day in autumn.

Above the court, Sinong Temple scoffed at Li Chengqian's proposal, and took off his official hat and put it in front of Li Chengqian as a gamble, inviting Li Chengqian to fight in the coming year: a piece of Tianzi number field, divided into two halves, Sinong Temple and the prince in half. If the crown prince wins, he will directly sue the old man (resign!). ）！ Li Chengqian was also full of confidence in his master, picked up the hat of Si Nong Temple, and said that if he lost, he would join Si Nong Temple!

"Of course!" Leng Feng's words were categorical.

Although he didn't know what happened to the accumulation of weeds in the dung, he did what the farmers did when he visited his grandfather in the countryside as a child.

Since the farmers do this, it must be useful, and in any case, it is better than using plant ash as fertilizer!

"That's good." Li Chengqian believed in Master, but he couldn't help but gain more confidence from Master.

As for Li Tai, he was very interested in the explosive methane gas that Leng Feng said.

Ever since Leng Feng demonstrated the dust explosion to him, Li Tai has become obsessed with the word "explosion". Now I cover my nose with a handkerchief and get close to the septic tank, thinking hard about what circumstances can I detonate this septic tank too.

As for Li Ke, Leng Feng deliberately made him Wei Chigong's partial general, followed Wei Chigong to transport cement to some key city passes, was responsible for explaining the application of cement, and was familiar with the composition of the army by the way.

After a busy day, when Leng Feng returned to the bedroom exhausted, Xiao Shuwen had already prepared the bath water.

Although this woman has left her lowly status, she is still used to doing some work done by subordinates.

Leng Feng has now learned to enjoy, lying in the bathtub and receiving Xiao Shuwen's massage.

Playing the piano can play the little hands that play the sound of nature, and the massage can also make people flutter.

Leng Feng knew that Xiao Shuwen secretly had correspondence with the queen, and the pigeon he shot down with stones that day had a note on it that said what Li Chengqian and Li Tai had learned in the past few days. The people of the royal family are all this virtue, they all like to find something from the subtleties, they all like to find many people as their eyes, even if they live in the deep palace for a long time, they want to know something that they can't see.

The queen is like this, and so is Li Shimin.

Yesterday, Wei Zheng went to the construction site to eat and drink under the guise of being hungry after inspecting the township, in fact, he planned to see if such a workshop could be promoted in the world. When he was full of wine and food, he told Leng Feng about the interesting things that happened in the court:

The emperor gave Fang Xuanling two beauties, but Fang Xuanling was afraid of guilt and let Mrs. Fang drive the two beauties away, and Li Shimin planned to hit Mrs. Fang's arrogance. So the lady who saw Fang Xuanling pointed to two beauties and a jar of black liquid and said: "You drive away these two beauties, that is, to resist the order, I will give you two ways, either bring the beauties back, or drink this jar of poisonous wine!" ”

Fang Xuanling knew the old wife's temper, and knelt down and begged the emperor to let her go, but Mrs. Fang's face did not change, and she drank the poisonous wine in one go.

In fact, the so-called poisonous wine is a jar of vinegar, and it is impossible for the emperor to really give the prime minister's wife to death. So that's the end of it.

After this incident, Mrs. Fang's name of "Mrs. Vinegar" spread......

Leng Feng didn't think that those two beauties were just a simple reward, it was estimated that they were the two pairs of eyes released by Li Shimin to spy on the high-ranking prime minister.

Who is Fang Xuanling? One of the "Fang Mou Du Cut", how could he stuff a time bomb into his home!

However, Wei Zheng's intention to tell this story is not ordinary...... is clearly pointing out that Leng Feng has Li Shimin's eyeliner by his side.

What does he want to do?
