The first batch of cement after two grinding and one burning was finally baked, and when the fourth team picked up Linghe City, everyone's eyes were attracted to the nearly 100 boxes of cement.

"What's this, ash, is it gunpowder?"

"I heard Lao Hong say that this is a secret weapon developed by Lord Yang." There was a lot of talking. Yang Fan dispersed the people who came around and said, "Go back and do your own work." Wait and so on to show you what this thing is for. ”

The people of the fourth echelon have already begun to pour baskets of cement on the ground, mix them with fine sand and gravel, mix them with water, and then turn them over a few times with a hoe, and mix well. Beginning to lead the buckets over, the bricklayer's tools for building the walls smeared the gray-black cement on the walls that had been built. The pouring on the top was almost completed, and many migrant workers rested for a few days before going to Tianluojing Mountain to reclaim the wasteland. The construction period was really shortened compared to the expected time, so you can imagine how enthusiastic everyone was. Yang Fan estimated that Zu Runze, this kid, was also back tomorrow, and he could sow seeds on the reclaimed wasteland.

The last process he envisioned was completed in advance. Qi Dabai was still burning cement over there. That's not enough to build a wall. Yang Fan told Qi Dabai to open up at full power, speed up the firing, and if it was too late, build another blast furnace. As a result, the fire at the foot of the Pingding Mountain was burning day and night, burning cement.

Yang Fan is like building this Linghe City directly with bricks, and then pouring it with cement and steel bars, making it very ironclad. But there was too late time, and he was not allowed to do this at all, so he had to think of a way like this, that is, to lay cement on the outside of the mud wall, which is a tofu slag project to put it bluntly. But this is the way it was done. When the cement is dry, such a grand city, Huang Taiji will not dare to storm it.

Zu Dashou walked out of the city and saw hundreds of people scraping the wall with ash paste, so he walked over curiously, and poked his finger, feeling no different from mud.

"I said Yangzi, this is what you said about cement? This color is like river mud, and the others are exactly the same as mud, and there is a chicken feather use? Zu Dashou pouted.

Yang Fan smiled: "It's really useless." "It's adobe on the inside, cement on the outside, like an egg, the shell is hard, and it's mushy on the inside.

"It's useless that you've been tinkering with it for so many days?"

Yang Fan said: "Let's not talk about whether your adobe wall can bluff Huang Taiji, just talk about this rain, this wall will have a lot of water, and it won't be long before it will be repaired again, right?" With this cement, it is no problem if it is not repaired for 30 years. ”

"Thirty years without repair?" Zu Dashou was taken aback, "You don't want to deceive the old man for ignorance." "If you want to say that the walls of the capital are all burned bricks, built up piece by piece, if you want to say that you will not repair it for 30 years, then the ancestor will still believe in it. This adobe wall, let alone thirty years, will be faintly loosened if it is not repaired for ten years, thirty years? To hell with it.

Zu Dashou said: "The Great Wall has been repaired and repaired, and you have to scrape your cement according to what you said, you don't need to repair it for 30 years, I'm really a ghost." ”

Yang Fan knows that the so-called Great Wall, known as the wonder of the world, except for a few famous scenic spots that are made of magnificent bricks and stones, many of the Ming Great Wall are rammed with mud, and many of them have lost their original appearance.

"Believe it or not, you'll find out in a few days." Yang Fan didn't explain much. Many of these fourth-echelon carefully selected by Yang Fan are from masons, so it is only fitting that this job will be handed over to them. It is estimated that in less than ten days, this tofu slag cement city will be completed!

With Yang Fan's status, Xiao Hei is also rising in the Thirteen Peaks, and there will be someone in charge of the forage for it to eat all day long, and sometimes when he is free, he will use a big brush to brush his whole body. At this time, Xiao Hei will submit to roll on the ground to show that he is satisfied with being served. Yang Fan saw that it was growing taller, and sometimes he was afraid that it would be too tired, so he ran back and forth to find another horse. So when Yang Fan was no longer there, Xiao Hei, who was full of spirituality, became the first brother of the Thirteen Peaks.

Zu Runze finally rushed back, and he came back with someone behind him. When Yang Fan saw the foreigner, he thought he was dazzled, and said, "You are ......"

"Yangzi, this is Ricci Priest. By the way, I brought you the potato you mentioned. Zu Runze took out a piece of cloth from his chest and said, "I carefully wrapped and wrapped the things you asked for, for fear that the road would be broken." ”

Matteo Ricci had never ridden a fast horse, and his skeleton was so torn that he almost fell to the ground as soon as he got off the horse. Shaking his head, he said, "Amen, it's finally here." Matteo Ricci swore that if he flew on horseback again, he would let the Lord take him back into his arms.

In the past two days, he had vomited everything he should have vomited, so that when he got off the horse, his feet were so weak that he could not do it.

Yang Fan hurriedly helped Matteo Ricci up and said, "Priest Matteo Ricci, what are you doing here?" Looking at Matteo Ricci's pale face, Yang Fan hurriedly ordered the people on the side to cook a bowl of rice porridge.

"Yang? Are you Yang? Matteo Ricci's eyes lit up.

"I'm Yang Fan."

"Great! Finally seeing you. I am Matteo Ricci, a believer in God, a missionary to Daming. Matteo Ricci revealed his identity with great politeness.

Yang Fan said: "I'm glad you came. I see that your face is not good, sir, why don't you go and rest first, and when your body recovers, let's talk? ”

Matteo Ricci was dazed and said in a loud voice: "Okay! Good! Then he was helped by the men to the tent to rest. Zu Runze pursed his lips and said happily: "It's really useless, I'm tired after only two days." said that he should not come, not to come, but he still insisted on coming. ”

"You think everybody is like you, like a bear." Yang Fan lifted the cloth, and a musty smell came to his nose. "I'll go, how long has this thing been there?"

Zu Runze said: "I don't know, I found it in the corner, how about it, can I eat it?" ”

Yang Fan glanced at Zu Runze and said, "If you want to die, you can eat it." "Not to mention that the sprouted potatoes are toxins, and if you eat them like this, you are killing yourself. Yang Fan muttered to himself: "I don't know if I can live or not." With that, he asked Zu Runze to transport the sack of sorghum seeds to Tianluojing Mountain. I'm following behind, researching how to get this thing into the dirt.

According to Xu Guangqi's reply to him, this sack of sorghum rice is enough to grow dozens of acres of land. Yang Fan didn't have much concept of this, and directly handed it over to those farmers to take care of it themselves. According to Xu Guangqi's words, if you want to Tuntian Ming Tombs, these sorghum seeds are just a drop in the bucket, and if you really want to be self-sufficient, you have to collect some more seeds. Yang Fan directly handed over these things to Zu Dashou and they were going to do it. What he has to ponder now is the problem of these rotten potatoes in his hands.
