Emperor: When will the Seventh Prince rebel? I will open the city gates to welcome him.

Mai Qingchang led his troops to Mangdang Mountain without stopping.

This mission is extremely important.

Soon, he informed the battalion commanders of the mission.

The battalion commander also conveyed the message to the company commanders.

So just one command goes down,

All the soldiers knew the importance of this mission.

Before they set off, Brigade Commander Mai Qingchang arranged for each of them to be fully alert.

At the same time, check whether you have all your weapons.

After completing these preparations.

The First Brigade of the First Army took horse-drawn carriages and headed for Mangdang Mountain.

Mai Qingchang commanded this brigade-level force of 5,000 people.

Five battalion commanders followed him.

The commander of the first battalion, Feng Tianyu, said:

"Commander! We are bringing so many vehicles with us. Are there really so many crossbows in Mangdang Mountain? I really can't believe there are so many crossbows. Three million crossbows is a number that I dare not even think about!"

"Haha! Whether there are really so many, we will know after we go there. There is not much point in guessing now!"

5,000 men from the First Brigade of the First Corps;

From the northern border, we went all the way to Mangdang Mountain.

Three days later, the troops arrived at Mangdang Mountain and saw from the outskirts that the place was heavily guarded.

These are all the Qilin Guards of King Zhenbei.

After being interrogated by the Qilin Guards of King Zhenbei, they entered Mangdang Mountain.

When we got close to Mangdang Mountain, we found that

Various workshops have been established around Mangdang Mountain.

These workshops are different from ordinary workshops and are much larger.

“This is refining iron ore!”

Mai Qingchang saw it at a glance.

A Qilin Guard came to Mai Qingchang and said to him:

"You are Mai Qingchang, commander of the First Brigade of the First Army Group, right?"

Brigade Commander Mai Qingchang saw the Qilin Guards bowing and said:

"I am Brigade Commander Mai Qingchang!"

The Qilin Guard smiled and said:

"You are the brigade commander! You cannot call yourself a lowly official in front of me!"

"The King of Zhenbei is calling you over in the military tent!"

"The King of Zhenbei called me over, yes! Then I'll go over now!"

Since he was sent there right after arriving as King of Zhenbei, it must be a very important matter.

As a subordinate, he certainly couldn't let the great King of Zhen wait for him, so after hearing the order from the Qilin Guard, he quickly entered the meeting room of the military tent.

In this military tent meeting hall, besides himself, the King of Zhenbei sat high on the throne, with the Qilin Guards on his left and right.

Hong Xuan said to the officer who was half-kneeling in the hall:

"Are you the brigade commander of the First Army?"

Mai Qingchang said respectfully:

"Reporting to the King of Zhenbei, I am the commander of the First Brigade of the First Army, Mai Qingchang."

Hong Xuan looked at the officer and said:

"The king called you here for nothing else."

"After you take this weapon away, you must not reveal the secrets of this place, and you must not reveal what you have seen. Do you understand?"

Mai Qingchang responded respectfully:

"I understand. I will never reveal any information about this place!"

"I will also strictly order the five battalion commanders to convey to the company commander that the information here will never be leaked."

Hongxuan nodded with satisfaction:

"Okay, now you follow Qilinwei to collect your equipment. After you collect it, you take this news to the commander of the Second Army and ask them to send a team of 5,000 people to collect the same amount of equipment!"

After saying this, the commander of the First Brigade of the First Army walked out of the military tent to collect his equipment.

Hongxuan watched the brigade commander leave.

I am extremely excited

"Finally, we can equip the army with sufficient weapons!"

"Unexpectedly, making military crossbows is much smoother than I thought!"

"The most important thing is that in this era, no one recognizes that such a huge mountain is actually all iron ore!"

"Now we just need to wait for each army group to be equipped with composite crossbows and crossbow arrows, then we can start our plan!"

"The more it is at this time, the calmer you need to be!"

Iron smelting is in full swing in this area.

After leaving the 1st Brigade of the 1st Army,

Soon, the Second Army sent a 5,000-man team from the First Brigade to Mangdang Mountain.

The commander of the First Brigade was Ning Zhongwei.

When he arrived here, he was shocked.

He never expected it.

The huge mountain in front of us turned out to be an iron mine.

There was a strange look in his eyes and he thought, "No! We must convey the news to the national teacher. King Zhenbei is too scary!"

The voice of the Qilin Guards behind him called out to him:

"King Zhenbei asked you to go to the military tent. I have something to tell you!"

Ning Zhongwei came to the military tent

Seeing the King of the North sitting on the throne, he bowed and saluted.

"Ning Zhongwei, the commander of the First Brigade of the Second Army, pays his respects to the King of Zhenbei!"

"Well, get up, no need to be so polite!"

Brigade Commander Ning Zhongwei stood up.

"I summoned you here to tell you that everything you see here must be kept secret! You must not let foreigners know about it. Do you understand?"

"I will obey your order. I will keep it strictly confidential!"

After saying this he stood up.

"Subordinates resign!"

Ning Zhongwei is about to get up and leave!"

Suddenly Hongxuan stopped him and said:

"Brigade Commander Ning Zhongwei, do you have anything else that you haven't explained?"

Ning Zhongwei was stunned. He didn't understand what King Zhenbei meant.

Hong Xuan narrowed his eyes and looked at the brigade commander:

"You can't go back for now, you have to stay here, you can't leave without my order!"

Ning Zhongwei was shocked. He didn't understand what he had said wrong.

This made King Zhenbei so suspicious of him.

Ning Zhongwei looked at the King of Zhenbei who was sitting on the high seat:

"Please forgive me, Lord Zhenbei! I don't know where I said the wrong thing, please let me know."

King Zhenbei looked at him and said with a smile,

"Under normal circumstances, wouldn't you need to pass on the orders that the king has given you to your soldiers?"

"How could you make such an obvious mistake?"

Ning Zhongwei, commander of the First Brigade of the Second Army, said in panic:

"I just missed it! After I go back, I will definitely convey the order of King Zhenbei."

Zhenbei Wang Hongxuan looked at him and said with a smile:

"I don't care whether you missed it or not. This place is of great importance. You cannot leave now."

"If you want to leave! You can only leave and leave your life behind."

Hong Xuan said to Qilin Guard:

"Qilin Guard! Go to the Second Army's First Brigade and select a company commander. Come to my tent."

The Qilin Guard bowed and accepted the order:

After a while, the Qilin Guard brought a young-looking company commander.

The young company commander was terrified. It was the first time he was so close to the King of Zhenbei.

He bowed quickly and said:

"Your subordinate greets the King of Zhenbei!"

After paying his respects to King Zhenbei, the young company commander saw his brigade commander standing beside him.

He looked at Brigade Commander Ning Zhongwei suspiciously.

King Zhenbei looked at the company commander from his high seat and said:

"What's your name?"

"Reporting to the King of Zhenbei! My name is Rong Zewen."

Zhenbei Wang Hongxuan said to the company commander:

"Rong Zewen, I now appoint you as the commander of the First Brigade of the Second Army!"

The young company commander was overjoyed.

"You will be tasked with escorting the weapons this time! You must keep it confidential and never reveal anything here!"

Rong Zewen responded:

"I will definitely fulfill my mission! Strictly order all company commanders and battalion commanders to keep this place a secret!"
