Upon learning that Annam intended to take treacherous actions against Yunnan, the border region of the Ming Dynasty, Zhu Yunwen immediately reacted.

He immediately sent an order back to the capital, requesting that 5,000 soldiers equipped with muskets and 1,000 light artillerymen be dispatched to Yunnan with their equipment and weapons.

In just two days, six thousand soldiers arrived in Yunnan with all their equipment.

The speed at which troops were mobilized was outrageous. Previously, mobilizing troops from such a long distance would have taken at least ten days to half a month, or even a month or two.

However, in just two days, an army was transferred from the vicinity of the capital to Yunnan.

Such speed is beyond description; it's so fast that even Mu Chun of the Mu Prince's Mansion finds it unbelievable.

This feels like a divine soldier descended from the heavens!

In fact, such a speed is not surprising, because Zhu Yunwen implemented the militarized management of soldiers throughout the country, similar to that of special forces in later generations.

Therefore, they were able to obey orders without question, and the roads in the Ming Dynasty were indeed in good condition. In addition, every soldier was equipped with a bicycle and a horse, and there were also tricycles for transporting supplies.

A tricycle carrying a light cannon and some shells and guns was no problem at all, a far cry from the arduous marches of the large armies of the past.

Therefore, it's quite reasonable that these armies are so fast now.

The key point is that in the past, when armies marched and fought, most of these soldiers did not have horses and had to walk.

The mountain roads were difficult to traverse, the terrain was treacherous, and the marching on foot made it extremely troublesome.

Now, not only are the roads better, but the soldiers are also riding bicycles, so it's not surprising that they can reach such a place in a very short time.

The key point is that they also use cycling as part of their physical training, so they inevitably chase each other along the way, and no one is willing to give in.

In this situation, the speed naturally increases.

Outside the Mu Prince's Mansion, in a spacious area, Mu Chun of the Mu Prince's Mansion was stunned as he looked at the army of six thousand men and the various cannons and muskets he had never seen before.

Although this army only numbered six thousand, he had a feeling that even his own regular army of over one hundred thousand would not be able to gain any advantage against these soldiers.

Standing to the side, Zhu Yunwen looked at the army below and smiled with satisfaction. He then turned to Mu Chun beside him and said:

"Where on the border is Annam currently most active?"

Mu Chun thought for a moment and said:

"It was probably most rampant in the Yuanyang County area."

Zhu Yunwen nodded slightly and said:

"Very well, in that case, I will personally lead the army to Yuanyang County. You will also take some of your troops. This move will surely create a powerful deterrent effect on Annam. We may even go to great lengths to infiltrate Annam and teach them a profound lesson."

Mu Chun nodded excitedly and said:

"Yes, sir!"

So, for the next day or two, Mu Chun was busy mobilizing troops and preparing provisions.

On the third day, he followed Zhu Yunwen, leading Zhu Yunwen's 6,000 firearms troops and the 100,000-strong army of the Mu family in Yunnan towards Yuanyang County.

Yuanyang County, as a border county between the Ming Dynasty and Annam, has been in a state of considerable disorder for many years.

There are many reasons.

This is because of the geographical environment of this border region, where the people live in dire straits and are frequently harassed by Annam, Myanmar, and other places.

The second reason is that Yunnan was not long after it was recovered by the Ming Dynasty, and it was not given much attention or strengthened management. It was almost ignored and neglected.

This further exacerbated the backwardness of the area and emboldened other countries along the border to oppress the local people.

However, things are different now. Since Zhu Yunwen wants to vigorously develop Yunnan, he naturally cannot allow the things that happened before to happen again.

In any case, Yunnan has been taken back by the Ming Dynasty, so it is now part of the Ming Dynasty's territory, and the people here are also the people of the Ming Dynasty.

In any case, in Zhu Yunwen's view, it was absolutely not the place for the surrounding small countries to oppress the people of the Ming Dynasty in this way.

Besides, I've worked hard to bring various industries to the forefront in Yunnan, and the tourism industry here has begun to flourish.

If tourists feel threatened by harassment of Yunnan's borders by other countries and thus stop visiting, wouldn't all the previous efforts be wasted?

Therefore, Zhu Yunwen would absolutely not allow such a thing to exist.

So, once everything was ready, the army quickly set off for Yuanyang County. Upon arriving in Yuanyang County, Zhu Yunwen discovered that although the population was small, it was actively responding to his policies.

The road is being repaired as quickly as possible, and many people are digging for various medicinal herbs or picking tea in the mountains.

Seeing this, Zhu Yunwen sighed helplessly. Faced with the covetous oppression and greed of the border enemies, they were still struggling to make a living.

So what reason did Zhu Yunwen, as the crown prince, have not to protect them?

What reason is there not to defend their rights as citizens of the Ming Dynasty and the life they are entitled to enjoy?

Therefore, Zhu Yunwen directly said to Mu Chun:

"Send your soldiers to ten groups to protect the safety of the people in various parts of the border. If they find any foreign enemies oppressing them, kill them all immediately."

You must do your utmost to ensure the safety of these border residents; this is your duty as the garrison commander of Yunnan.

Seeing Zhu Yunwen's serious expression, Mu Chun dared not delay and immediately went to issue the order.

Following Zhu Yunwen's instructions, Mu Chun divided his 100,000-strong army into ten routes.

Each route had 10,000 troops dispersed to various border areas to protect the people on the border and prevent them from being oppressed by the border enemies.

And at any time, he would report the situation to Zhu Yuntong and Mu Chun, who were in Yuanyang County.

That very evening, news came back that four groups of soldiers, after arriving at different locations, had all encountered Annam soldiers massacring villages on the border.

Fortunately, the Ming army that arrived from the northeast wiped out the enemy and did its best to ensure the survival of the civilians.

Although some civilians had already been massacred by the enemy, Zhu Yunwen only felt heartbroken about it.

Fortunately, from this moment on, the border was protected by the army, which could guarantee the safety of the border as much as possible.

The people would no longer suffer from the brutality of foreign enemies, but the swift response of the Ming army also provoked Annam.

So, starting the next day, the enemy soldiers who had been roaming the Yunnan border areas gradually began to gather together, preparing to fight the Ming Dynasty's border army.
