Guangzong Yaoming

Chapter 301 Internal and External Strength
It will not be until the end of February in the lunar calendar that the cold north will gradually thaw.

At this time, it was not suitable for the tribes on the grassland to start a war because they had to breed livestock and fatten the sheep and horses.

They are accustomed to taking action after autumn.

Correspondingly, if the Han army in the south wanted to harass, they would start their attack during this season.

The snow will melt, and even though it will be muddy, it is better than fighting in the ice and snow.

If it is just harassment, it is called burning the wasteland.

This time it was not harassment, but there was also burning.

The Khalkha tribes within the Liaohe River and the right wing of the Khorchin, especially those living south and west of the Liaohe River, had not seen the Ming army on the grassland for a long time.

On the flat Liaohe Plain, there are no easy-to-defend and difficult-to-attack passes outside the Ming Dynasty's border wall.

The Ming Dynasty has been so mobilised into war, how is it going to defend itself in the future?
Chaohua couldn't figure out this problem, but now he had to protect them.

"Duling, the Ming army from Guangning has come out. Aren't they really afraid of fighting us on the grassland?"

"…Since they dare to come, let them have another taste of the iron cavalry!"

Chaohua's face was gloomy, and he felt provoked and humiliated.

As the wind direction gradually changed to the south, the Ming army burned the wasteland along the way and advanced steadily northward.

It is a full-scale advancement from Kaiyuan to Guangning!
They crossed the Liao River before it thawed, and pressed forward in groups, as if they were not afraid at all of the cavalry attacking them or cutting off their retreat or robbing them of their food supplies.

Daming is crazy!
The Tatar tribes in the Liaohe area have not dealt with this kind of situation for many years. There are many directions to defend, but the Inner Khalkha tribes and the Khorchin tribes are not united and have a unified command.

Even Chaohua had no way to convince his other brothers to concentrate their forces and inflict heavy damage on the Ming army in one direction.

Everyone is on guard against that tough guy who appears out of nowhere from the north.

"...Go to Naiman and tell Ecan that I'm going to fight the Ming army. If he wants to help, please help us watch the north!" Chaohua gritted his teeth and said, "Pass the order down and start the transfer to the south!"

The herdsmen live near water and grass, and every time at this time, they start to migrate.

If we want to go and fight back, it would be inconvenient to split our forces and leave behind only one tribe, so we might as well go together.

The Ming Dynasty had such large-scale burning, Chaohua didn't believe that the various tribes would still do the same when it came to survival.

As long as we win the first battle, they will gather around us.

So far, except for the Tianshu Camp, the Ming army and the Tatar tribes have not officially engaged in battle.

And in the far east, in the lower reaches of the Tongmon River, the Korean border troops once again saw the Jurchens appearing on the other side of the mountain pass.

There was a huge crowd of them, far more than the group of Jurchens who robbed and killed their own people last year.

At the Wujie Rock, Nurhaci looked at the battlefield of last year, looked at his eldest son and the generals who won a great victory there that day, and then raised his arms and shouted: "The Jianzhou tribe is invincible! Last year, 300 Jianzhou warriors defeated the 10,000-strong army of the Ula tribe! This year, 30,000 Jianzhou warriors will surely flatten Korea and establish a country that belongs to us Jurchens! Kill!"

"kill!"

The North Korean border troops turned pale when they heard this.

Looking around, there were no other enemies, and it didn't look like the Jurchens were going to fight each other again.

In front of them were only the Korean border troops.

The strong winds from the entire north of the east finally started to blow, and spring came to Beijing.

For Zhu Changluo, all that was left was to wait.

Waiting for battle reports, waiting for victory reports, waiting for new military intelligence.

How to adjust and how to ensure logistics.

As an emperor, doing these things sometimes feels like playing a strategic game. After all, he only needs to determine the direction, give orders, and then wait for the results.

But he was in the middle after all, and every order he gave involved human lives.

There are also many unpredictable variables. So I just continued to spend my time in the Boyan Institute and Baijiayuan.

Galileo had learned Chinese quite well and was able to communicate directly with Zhu Changluo.

"You want to observe comets, just to prove that the earth revolves around the sun." Zhu Changluo said, "In this regard, the Ming Dynasty Imperial Astronomical Observatory has a wealth of information. From ancient times to the present, every dynasty in China has a special history museum that is responsible for recording history. They have detailed and reliable information that can help you."

Galileo has already felt the benefits of being in the Ming Dynasty.

The emperor was very open-minded and supportive of his work.

But the most important thing is that there are indeed too many historical records in the East, piled up like mountains.

Observing the stars is not something that can be done in a day or two. Although the telescope has been improved once, it will still require long-term observation and recording to prove one's point.

Instead, the emperor wanted him to spend more time on another matter now.

"Mathematics is more important, and rigorous experimental methods are more important." Zhu Changluo said, "Even if you observe the stars, their speeds and trajectories will eventually require mathematical formulas to reveal the mysteries. Let's start with the many existing laws, levers, parabolas, pendulums, didn't you say you studied them back then? If Kepler could come, you also said he was more interested in astronomy and optics, you could study together, and he would also need your mathematical help."

Zhu Changluo had persuaded him to write a letter to Europe to ask Kepler if he was willing to come.

Moreover, Zhu Changluo also told him that he could bring his lover and children over. In the Ming Dynasty, his survival and experimental expenses would not be a problem.

"Your Majesty, the other day you mentioned three observations about force. Lord Xu, Lord Wang and I have been thinking about them. It is incredible that such a concise statement, when combined together, seems to be able to explain most of the motion phenomena. I would like to discuss it with you again..."

This is Zhu Changluo’s ultimate move.

I don’t remember much, but I do remember the three most famous laws of classical mechanics.

Now, Zhu Changluo has made specific requirements for them to establish and improve mathematical standards. The topic given is to start from these three laws, to experiment and extract clear mathematical expressions.

This will allow more people to verify and will also bring up more questions.

After all, the current experimental environment is not a vacuum, and there will be external variables such as altitude, air pressure, wind speed, etc.

Of course, for Galileo, the emperor's concise summary of mechanics was too shocking.

He increasingly felt that unimaginable mathematical achievements might be possible in the East.

Zhu Changluo was happy to discuss with him, but he also called Wang Zheng, Zhu Zaiyu and others.

Outside the border wall, the Ming army was on the move.

In the Forbidden City, the emperor was guiding the scientific talents he had recruited to study.

Spring is here and flowers are blooming, but we don’t know how long it will take for these decisions and actions to bear fruit.

But Zhu Changluo was officially on the road.

In the Liulichang on the outskirts of Beijing, master craftsmen are still improving glass.

In a corner of the Academy of Scientific Research, Taoists were tinkering with the acids, alkalis, and mercury that the emperor had mentioned.

The emperor didn't want them to make elixirs, which gave some Taoists a headache because they truly believed that they could attain enlightenment by taking the essence of all things.

But there are also some Taoists who are more indifferent, or more worldly. You know, this thing... is just a technique to keep yourself safe.

But being able to practice freely is a good thing, right?
Alchemy is very expensive, and the various materials are very valuable.

The benefits of having an adequate supply of raw materials to improving craftsmanship are immeasurable.

They were looking for the thing the emperor had mentioned, which would explode without being ignited but with a single violent shock. It was a very dangerous thing.

But if the quantity is small, the power won’t be that great, which is okay... after all, I have an apprentice.

In the Taichang Temple, Li Tingji had a serious look on his face.

"Your Majesty is now studying with the Western barbarians!"
