Zhu Su once saw Lao Zhu mobilize workers to build the Yingtian City Wall: First, he collected solid stones to make the city base, and then burned thousands of city bricks to make the wall. Glutinous rice mortar was used between the city base bricks.

And mortar such as quicklime is used to fill the joints, so that the city wall bonded is very strong.

The Ming city wall of Yingtian Mansion has indeed stood safe and sound on the land of China for hundreds of years.

But in Zhu Su's view, the city wall built in this way is time-consuming, labor-intensive, and expensive. Just a short section of the city wall often needs to be stacked, tamped, and stacked dozens of times. And it is not easy to boil the glutinous rice mortar.

, you must know that glutinous rice is food! At the beginning of the Ming Dynasty, the cost of glutinous rice as the raw material was already worth a lot of money.

Zhu Su was extremely dissatisfied with the effect of the glutinous rice mortar cooked at such a cost: the bonding took a long time, often taking more than a month. It was best not to be exposed to rain during the process. It also needed to be compacted layer by layer, and brackets needed to be put on the outside.

To serve as support... The city walls are obviously used to protect soldiers and defend against foreign enemies, but they are made to be more delicate than the people themselves.

Precisely because construction is difficult, the locations where cities could be built in ancient times were also very limited.

Zhu Su was very dissatisfied. Did the ancient Chinese use this stuff to build majestic cities that would go down in history? The hard work of craftsmen should not be wasted on delicate adhesive materials!

Make cement! You must make cement! With cement, such a towering city wall can be erected in just a few months! Building a city in the Northern Desert is no longer impossible. With the support of the city wall, the radiation range of the Chinese nation can be further expanded.

Thousands of miles away!

Zhu Su was relatively good at studying in later generations. For example, he dabbled a little in the guide books known as "must-have time travel" for later generations of time-travel enthusiasts, "Friends of Military and Civilian Talents", "The Barefoot Doctor's Manual" and other books.

.But theory is just theory after all. If you want to truly burn cement, you still need to keep trying.

It’s not just cement, but also glass, firecrackers, etc. The steam engine is too far-fetched and it’s a bit impossible. At least in your lifetime, you have to come up with a breech-loading flintlock pistol, right?

In the future, if I have the opportunity to fight against a certain Shanyu in front of the army, the Shanyu loudly challenges my fifth prince Zhu Su. Amidst the exclamations of condolences, I rush out of the danger without hesitation, facing the Shanyu who is galloping away.

The coming Kuai Ma Scimitar calmly took out his pistol, bang!

Shanyu fell off his horse in fear, blew the smoke from his gun, and left behind a sentence: "Stupid barbarians, times have changed." Then he floated back to the battle, and in the eyes of Shanyu when he was dying, a silhouette that was invincible in the world was reflected...

…

This scene makes me emotional just thinking about it!

"Brother Su? What are you thinking about?" Mu Ying called.

"Nothing..." Zhu Su quickly wiped his saliva. Although it would be great to kill the enemy chief unexpectedly with a pistol before the battle, it is still too dangerous to go to the front line. A gentleman does not stand in danger, think about this.

That’s it…

Zhuangzi's visit was basically like this. Mu Ying and Zhu Su rode their horses and wandered around. It was the turn of summer and autumn, and there was no wave of wheat that was about to mature in the fields as Zhu Su had imagined. The wheat appeared green and yellow, extremely sparse, tall and short.

They are also different.

Compared with the rickety old farmer who was working hard in the fields with his trousers rolled up, the scarcity of the wheat made Zhu Su angry.

….

"Is this a disaster year?" Zhu Su asked Mu Ying.

"Huh? Why do you ask? Although this year is not a bumper harvest, it is probably a good year."

Mu Ying looked at the old farmers working in the fields and showed an expression of relief that was completely different from Zhu Su's. "In the B.C. Yuan Dynasty, where could we see such a scene of people farming happily? People at that time had no way to survive, even if they were farming.

, they are also plowing for the master's family. As soon as the wheat begins to grow, the dog officials of Yuanting will come to cut a crop. Not even a bit of the food grown can reach the people's mouths!"

"If it weren't for me, the Ming Dynasty, how could we have such a peaceful and contented life?"

Such a scene is peaceful? Zhu Su felt that Mu Ying's words were a bit horrifying. If such sparse wheat stubble can be regarded as a scene of living and working in peace and contentment, what kind of hell would it be if the people recorded in the history books of the Mongolian and Yuan Dynasties were in dire straits?<

/p>

This kind of farmland was considered a disaster in Zhu Su's eyes. In the eyes of the court, officials, and even the people, it turned out to be a good thing that required gratitude

New Year?

"It shouldn't be like this..." Zhu Su murmured.

"What?" Mu Ying asked.

"Nothing." Zhu Su forced out a smile and looked at the old farmer with a smile on his face, but his heart became heavier.

The people on this land are the most hard-working people.

They don't deserve just this.

"Brother Muying, when can we move to this Zhuangzi?" Zhu Su asked. He couldn't wait now and wanted to try to do what he wanted to do in Zhuangzi. After all, there were too many rules in the palace, and even digging in the harem

There were eunuchs kneeling in the sand pit for exercise, saying that it would ruin the feng shui. If you want to do something, you can't do it in the palace, or you will be annoyed to death.

"In another half month, this Zhuangzi will be completed." Mu Ying said. He walked side by side with Zhu Su, stretched out his arm and patted Zhu Su on the shoulder: "But by then, I'm afraid I won't be able to come here to keep you company."

."

"Huh?" Zhu Su was a little confused. "Didn't he say that my father asked you, Brother Mu Ying, to temporarily lead King Wu's guards?" Before the village was built, Lao Zhu told him that he would ask Mu Ying to train guards for Zhu Su and protect the palace.

Mu Ying is a talented general, so being Zhu Su's bodyguard is an overkill. With Mu Ying protecting Zhu Su, he feels at ease.

Why have you changed your mind now?

"It was originally arranged like this. But the Governor's Office issued a mobilization a few days ago and asked me to lead troops to Yunnan." Mu Ying said with a smile. "It has been my long-cherished wish in my life to fight for the country. My adoptive father has high hopes for me.

I can't bear to disobey him. But I broke my promise to you..." His expression was a little tangled.

"Why don't you break your promise? Taking Yunnan is a national event! Brother Mu Ying, you are my famous general of the Ming Dynasty and my Wu Wangwei is unreasonable. Now that the Ming Dynasty needs you, why should you break your promise!" Zhu Su quickly called.

I stopped him. But I felt strange in my heart: According to the original history, it would have been several years before the Ming Dynasty conquered Yunnan. Why did they mobilize their troops to Yunnan now?

It seems that Lao Zhu can’t wait to clean up this big stall to recharge his batteries.

"Don't worry. Didn't you also say that conquering Yunnan was not difficult in history? It was my adoptive father who had his own considerations a few years earlier." Seeing Zhu Su's worry, Mu Ying comforted Zhu with a smile.

Su told him about the conquest of Yunnan, and told Mu Ying as many historical details as he could remember, in order to enable Mu Ying to make plans early and make the conquest of Yunnan smoother.

However, Zhu Su did not tell him about Mu's future return to Yunnan. Out of gratitude, Zhu Wenzheng's tragedy had made Zhu Su understand the consequences of having too high expectations. He did not want Mu Ying to have any

The opportunity and signs of the split with the Zhu family, after all, what if Lao Zhu doesn’t want to make Mu the king of Yunnan?
