At the age of 39, Zhu Yuanzhang, who was in his prime, personally took charge of Kaifeng and formulated the first Northern Expedition plan of the Ming army, taking Shandong first and entering Shanxi sideways. In order to avoid the head-on battle of the Yuan army, he quickly recovered the two places and surrounded the Northern Yuan court in a corner.

Xu Dachang Yuchun made a Northern Expedition. Before he arrived in Dadu, Emperor Shun of Yuan ran away. Why? Of course, there were no troops available in Zhili area, and all reinforcements were blocked by Lao Zhu and could not be supported.

It seems that Zhu Yuanzhang has become the pinnacle of the Ming Emperor's merit book.

If future generations want to surpass him? Be the chief!

Zhu Gaochi said: "Grandpa's achievements are naturally not comparable to me, I hope they can match them. If it is just Dongfan, how many indigenous people are there on Dongfan Island?"

Zhu Gaochi wiped the tears from the corners of his eyes. Fang Shiyu wanted him to cry, so he cried without any ambiguity.

"I don't know this. Most of the indigenous people in the East Band were from the Song Dynasty after the fall of the Song Dynasty. The court is not sure about the specific number. If you have any requirements, you can also tell me as much as possible."

Seeing Zhu Gaochi's appearance, Fang Shiyu looked calm and said to himself: "Emperor Renzong is indeed Emperor Renzong. He just observed his words and expressions with this move, and was not surprised. Zhu Gaoxu was far from being inferior."

Zhu Gaochi said, "Well? The court doesn't know, that's nothing more. Brother, what should I do when I go to Dongfan? I always have to make money to support people's livelihoods. Otherwise, no matter how hard I work, there is no way." Zhu Gaochi shrugged. He did know how the primitive tribe developed rapidly, and Dongfan was near the Penghu Islands and was backed by the imperial court.

Except for the extremely special things that cannot be obtained, Zhu Gaochi is still very confident whether it is farm tools or seeds.

Fang Shiyu said: "Dongfan, it's hard to say about this ancestor. The climate over there is a tropical climate. The ancestor has never been there. There is no good way to ask Dongfan to do something specifically."

Zhu Gaochi nodded and said, "That's hard to deal with, I still have to think about it."

Just as Zhu Gaochi was talking, Li Wan and Zhu Ziyi walked in and Feng Cheng and Zhu Gaochi stood up and saluted, "Greetings to the princess."

"I'm not so surprised. I'm here to share it with you. This thing Gao Chi brought back is so sour and delicious."

Zhu Ziyi held a plate in her hand and placed it on the table. Fang Shiyu was stunned and her eyes were frozen: "This thing?"

"Master, this delicious thing was given to me by some tribal forces at the southern end of Dongsheng Shenzhou, and I brought some back."

Zhu Gaochi didn't see him at all, and picked up a piece and chewed it in his mouth.

After swallowing his saliva, Fang Shiyu said, "Don't you don't know what Dongfan is doing, just plant it. Dong Zhu Gaochi was stunned and said, "Has the ancestor eaten it?"

"Isn't this a matter of time? You took the officers and soldiers and the civilians to Dongfan, and then reclaimed wasteland and planted this thing."

"It just so happens that it can enrich the fruit and vegetable varieties of the Ming Dynasty, it's amazing."

Fang Shiyu had a smile on her face. The uncontrollable joy was really very happy.

A magical smile.

The people at the bottom of the Ming Dynasty were living a little difficult, even after Fang Shiyu got three high-yield crops: sweet potatoes, corn and potatoes.

Food can indeed fill the stomach, but the Ming Dynasty still lacks a lot.

Zhu Gaochi ate the pineapple and said to Fang Shiyu: "Master, I want to go to Nanjing."

"Go, go."

Fang Shiyu's face was calm. These juniors came back from overseas and should pay homage to Zhu Yuanzhang.

After discussing with Zhu Gaochi for half a day, Fang Shiyu stretched her waist lazily, wandered around the Qianqing Palace, and said with a irritable heart: "This kid is getting smarter and smarter!"

"I'm smart when I'm a little bitch. I've been practicing overseas for so long, and it's not inevitable that I'll become smarter!"

Zhu Ziyi shrugged. She was too familiar with Zhu Gaochi.

Nodding, Fang Shiyu said, "It's better that he is smarter, otherwise, Dongfan will not be so easy to deal with. How can it be much smaller than Dongsheng Shenzhou?"

Primitive tribes are dense, and there are also cannibals.

"I hope he can get the East Band soon." Fang Shiyu sighed softly.

Zhu Ziyi hesitated: "If he has done the Eastern Band for ten or eight years, what do you want him to do? Go overseas and become a vassal?"

"How is that possible? Gao Chi's talent has not been used clean yet. When he gets done with Dongfan, let him be a cabinet minister in the cabinet."

Fang Shiyu smiled slightly and said softly.

Zhu Ziyi looked surprised and said in surprise: "Cabinet?Cement ministers?"

"You think, the other vassal kings are all one place. If I give Zhu Laosi's family two places, what will it become?"

As he said that, Fang Shiyu shook his head. Just when Zhu Ziyi was confused, Wei Hong walked in and said, "Your Highness, Minister of Revenue Zheng Ci asked for a meeting!"

"Zheng Ci? Let him come in!" Fang Shiyu said casually.

After entering the Qianqing Palace, Zheng Ci said, "I am paying homage to Your Highness."

"Okay, if you have something to do, tell me!" Fang Shiyu said impatiently.

Zheng Ci bowed and said, "Your Highness, the cement has been effective. It is indeed very hard, and it is relatively convenient to use, not as picky as the city bricks!"

Upon hearing this, Fang Shiyu was obviously stunned for a moment, and Zhu Ziyi, who was beside him, said, "You talk first, I will go back and rest!"

He smiled awkwardly and sent Zhu Ziyi away. Fang Shiyu hurriedly pulled Zheng Ci and said, "Come on, tell me what the effect is!"

Although this thing was handed over to Lao Luo before, because there were too many things, Lao Luo passed away and now he has to teach it again.

"The cooling speed is barely enough. It's about two days old. The hardness is very good, far from comparable to that of city bricks. The most important thing is that the process is simple and clear, and it is not complicated at all.

The difficulty of manufacturing process alone is much simpler than that of bricks, and cement has the possibility of large-scale production."

Zheng Ci hurriedly spoke.

Before he came, he had just experimented with a cement board. At that time, Zheng Ci didn't believe that the cement had such strong hardness.

The serious hammer hit a few times. Although the huge hammer caused gravel to the cement board, the angle of the huge hammer was enough to smash a brick into powder in one go.

Seeing this scene, Zheng Ci had a new understanding of the hardness of the cement board, and then he hit it twice with a small hammer, although some mud spots were shaken off.

But that was also the damage to the cement board caused by the heavy blow of the sledgehammer.

Fang Shiyu's eyes were deep and she said with a smile on her face: "Go and take a piece and show it to me!"

Zheng Ci bowed and said, "Report to your highness, I have someone to bring you Qianqing Palace, right in the yard!"

Fang Shiyu didn't doubt that he was there and took a step out of the palace. In the huge courtyard, he could see three cement boards piled up together at a glance.

The top piece has a crack, which should be Zheng Ci's test piece.

Although the hardness of these three cement boards is not as good as that of later generations, Fang Shiyu's hardness should be stronger than the current city walls.

But if we compare the dams of the earth and stone buildings in the Ming Dynasty, it would be an obvious epoch-making progress.

Fang Shiyu nodded meaningfully and said, "With this thing, he can use it to make the outer city wall!"

Zheng Ci quickly retorted: "Your Highness, this is absolutely absolutely forbidden!"

"No?" Fang Shiyu was slightly stunned, looked at Zheng Ci, and said suspiciously.

Zheng Ci said: "Your Highness, I believe that taking this thing out alone will be harder than the city bricks used in the city wall, but the city bricks used in the city wall are the most important riveting technology."

"While it is relatively soft, it has a certain degree of toughness. If this thing is used, according to the current artillery fire power of the Ming Dynasty, its effect will be far inferior to the defense of the city wall!"

As soon as Zheng Ci finished speaking, Fang Shiyu hesitated: "Then let's organize an experiment first, and I'll try how hard this thing is!"

Fang Shiyu still understands the principle that it is easy to break even. If this thing is really not suitable for use on city walls, it is not used now. In a few hundred years, the existence of the city wall will not be so important.

Wei Hongcai, who was standing beside him, raised his little hammer, and slapped Fang Shiyu a few times, and said in surprise: "Your Highness, this thing is really hard..."

Since it cannot be used for city walls, then it should be used to build houses. How much does this thing cost?" Fang Shiyu asked. Since it can achieve large-scale mass production, the price will be much lower than that.

Zheng Ci said: "The cost is low, but if it is used to build a house, Weichen believes that it is not a good place to go. Wooden houses are the fundamentals! Although this thing is good, it cannot replace wooden houses at all."

"And if you use this to build a house and use wood as a support, the wood will be wrapped in it sooner or later, and the safety will not be guaranteed."

Fang Shiyu had a clever mind and said in his mind, "Cement building must have a steel structure. It is definitely not safe to rely on cement alone."

As if Zheng Ci woke up, Fang Shiyu asked, "Then tell me, what should this be used for?"

Zheng Ci said bluntly, "It is OK to build bridges, pave roads, and sort out river dams."

Build a bridge, pave the road, and organize the river dam. By the way, go back and simulate it, use it to build a small river dam, and see how much waterlogging it can withstand."

"You must remember how much you bear!"

Fang Shiyu looked at the cement board in front of him, which could not be used on the city wall or built houses, but it did not prevent him from shining and heating in all walks of life in the Ming Dynasty.

The official road has just been built, and it is time to lay a layer on the official road. It is another terrifying project to use cement to smooth the road surface. Fortunately, the cement is still passive. Although I don’t know if the river dam can be done, there is definitely no problem in repairing bridges and paving roads.
