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

Yes! Zhenbei Wang Hongxuan gave a letter of challenge.

The core content of the declaration of war was not to ask the Northern Territory National Master Yun Yi to release the tens of thousands of soldiers trapped in Baidi City.

A big gamble!

The stakes are Yun Yi's life and the lives of the surviving soldiers in Baidi City.

Or perhaps from the very beginning, King Hongxuan of Zhenbei had no intention of actually rescuing the trapped soldiers of the Dafeng Kingdom, but rather of using these soldiers as a bet.

Since it is a bet, there are winners and losers.

If he loses, the King of Zhenbei will then kill the National Master Yun Yi, the Lord of Beishang, Ba Xin, and all the dignitaries of Beishang on the front battlefield.

Only in this way can Zhenbei King Hongxuan achieve true rule.

The tens of thousands of soldiers trapped in Baidi City were used as sacrifices to help Zhenbei King Hongxuan destroy the Beishang Kingdom.

If you win.

The Beishang Imperial Master really released all the tens of thousands of soldiers trapped in Baidi City.

So what are the consequences?

The 300,000 cavalrymen of the entire Beishang Kingdom would create a serious rift in the majestic military power of him as the national teacher.

And it's a crack that can't be healed.

Supreme Commander, letting the enemy go, and letting the enemies who once killed 220,000 cavalrymen of the Northern Shang Kingdom go, is not just a matter of shaking the morale of the army.

If this matter spreads.

He, the national teacher, and the Yun family will be wiped out at the first opportunity.

Yun Yi frowned and muttered to himself:

"The most critical issue today is the challenge from the King of Zhenbei. How should I choose? What answer will the King of Zhenbei give?"

"Obviously, his answer was that whether he won or lost was all within his calculations."

"Humph! Good trick! My master doesn't believe you can really come up with a weapon more powerful than the composite military crossbow."

Yun Yi didn't have time to think about it anymore. He didn't believe that the King of Zhenbei could come up with a battlefield weapon more powerful than the composite military crossbow!

He has made his choice.

"Ziyun! Order General Peng Riqiang's South Camp and General Ji Xuelun's East Camp to retreat southwards and prepare for an ambush. Wait until all the Dafeng soldiers leave Baidi City. Then let General Wei Kunhua's West Camp and Xu Xian's North Camp combine to quickly occupy Baidi City. Then, these Dafeng soldiers who have withdrawn from Baidi City will be attacked from both sides and annihilated!"

"Humph! The King of Zhenbei wants to sacrifice tens of thousands of soldiers' heads to the flag, so this national teacher will grant your wish!"

Hongxuan issued a declaration of war from the beginning, so Yunyi had no choice but to follow Hongxuan's path.

Ziyun retreated and conveyed Yunyi's order to the four military camps.

After leaving the tent, Qilin Guard headed straight for Baidi City, and no one stopped him on the way.

The Qilin Guards successfully approached Baidi City, and the army soldiers standing on the commanding heights soon discovered the Qilin Guards.

"Who are you? Don't come any closer, or I'll shoot you!"

Qilin Guard hurriedly said:

"I am Qilin Guard, the personal guard of King Zhenbei. Open the door quickly and lead me in! Convey the order of King Zhenbei!"

After hearing the news, the soldiers on the city wall hurried to report it to Zhao Bencai.

Army commander Zhao Bencai was overjoyed when he received the news, but he did not open the city gate. Instead, he ordered the Qilin Guard to be pulled up from the hanging basket.

Qilin Guards arrived at the main hall of Baidi City.

The commanders of the First, Second and Third Armies are all in place.

Qilin Guard looked at them and said:

"King Zhenbei has issued an order for all of you to leave Baidi City and return to Beijing City."

Zhao Bencai looked at Qilin Guard and said:

"We are all surrounded. How can we leave?"

"Is this really an order from the King of Zhenbei?"

Qilin Guard said:

"King Zhenbei sent me to Yun Yi to deliver a declaration of war. After delivering the declaration of war, I will lead all your soldiers to leave Baidi City and return to Beijing City!"

"Whether you live or die, that depends on God's will. The prince already knows that you are short of water here, so you must not stay any longer. In short, if you stay in Baidi City, you will definitely die!"

Zhao Bencai considered what Qilinwei said and decided that leaving Baidi City this time would be dangerous.

"This general will obey the order of King Zhenbei!"

Zhao Bencai assembled all the soldiers, a total of 50,000 people.

When 50,000 people had gathered, Zhao Ben said to everyone:

"All soldiers, obey the orders of this commander!"

"The King of Zhenbei has issued an order to this commander. He has sent 60,000 soldiers from the Northern Border City to pick us up."

"The prince's soldiers and our 50,000 soldiers, a total of 110,000! No matter how powerful the Beishang cavalry is, they can't resist it. They will be attacked from both sides!"

"All soldiers of the army, bring all the kerosene. The chariot and horse shields are afraid of the attacks of the chariot and horse shields."

When Qilin Guard heard this, Zhao Bencai lied when he mobilized the soldiers to leave.

The King of Zhenbei did not tell him at all that he would send 60,000 soldiers to support him.

Why does Zhao Bencai just talk nonsense?

What the Qilin Guards didn't know was that it was because of Zhao Bencai's command that the army was able to save the lives of 50,000 soldiers.

If it weren't for Zhao Bencai's command, the entire army would have been destroyed by now.

All the soldiers in Baidi City believed Zhao Bencai's words without a doubt. They believed that King Zhenbei must have sent a large number of troops to welcome them back to Beijing City.

The army is assembled.

All soldiers should bring enough military crossbows and arrows. There are large stocks of these crossbows and arrows in Baidi City, and there are still as many as 30,000 military crossbows.

But we couldn't take all the soldiers of the army with us.

Zhao Bencai ordered that all military crossbows that could not be taken away should be destroyed on the spot.

All 30,000 military crossbows in stock had their bowstrings cut and bow bodies chopped off by long swords.

After doing all this, Zhao Bencai took all his troops and left Baidi City. Even if they wanted to stay in Baidi City, there was no way.

Because there is no water source in Baidi City.

The scouts surrounding Baidi City discovered that all the trapped Dafeng soldiers had left Baidi City.

The army led by Peng Riqiang in the South Camp and the army led by General Ji Xuelun in the East Camp, with a total of 150,000 troops, were determined to wipe out these 50,000 Dafengguo soldiers.

The 150,000 troops in the West Camp and the North Camp were responsible for occupying Baidi City and cutting off the retreat route of the 50,000 Dafeng soldiers.

Zhao Bencai realized that as long as he and his soldiers left Baidi City, the only way they had was to break through the Beishang Kingdom's chariots, horses, shields and cavalry.

Yun Yi of the Northern Shang Kingdom handed over all the captured crossbows to Peng Riqiang of the Southern Camp.

So the South Camp is now the most powerful force.

Zhao Bencai led 50,000 soldiers of the Dafeng Kingdom and marched southward. Before they had gone five miles, they saw from afar that the cavalry of the Beishang Kingdom had already taken up their positions in front of them.

Only then did Zhao Ben realize that all the soldiers of the Dafeng Kingdom would be buried here, including himself. He shouted angrily:

"The support of the King of Zhenbei has been dispatched. All soldiers, prepare your crossbows! Follow the orders of this commander!"

"Ready! Shoot!"

"Ten thousand arrows fired at once! Fifty thousand military crossbow arrows fired!"

General Peng Riqiang of Beishang State was not panicked at all when he saw the crossbow arrows shot at him, and gave the order directly!

"Chariot and Horse Shield!"

"Open the shield!"

The cavalrymen of the Northern Shang Kingdom all hid under the large shields of the chariot and horse shields.

General Ji Xuelun looked at the crossbows that were coming at him and said with a smile:

"Haha! These 50,000 Dafeng soldiers will all be killed by us today!"

On the battlefield, Zhao Bencai roared:

"Rockets! Load the crossbows with flaming oil!"

"Shhhhhh!"

Tens of thousands of crossbow arrows loaded with kerosene were fired at the same time, but they were still blocked by the chariots, horses and shields.

After these days of transformation.

Yun Yi had already replaced all the wooden parts of the chariot, horses and shields with iron ones.

This is to prevent the crossbowmen of the Dafeng Kingdom from attacking with kerosene. This fire attack must be carried out unexpectedly to catch the enemy off guard, in order to be most effective.

However, the kerosene shot onto the shields of the chariots and horses quickly burned up the oil on the crossbow arrows.

They went out one after another.

"God wants to kill me, Zhao Bencai!"

"All soldiers of Dafeng! Listen to the command of this commander! Charge! Charge! Charge! Fight with the cavalry of Beishang!"

Just when Zhao Bencai wanted to fight to the death.

A force of 60,000 crossbowmen aimed at the front and shot tens of thousands of crossbow arrows from behind the military formations arranged in the South Camp and the East Camp of the Northern Shang Kingdom.

"Shhhhhh!"
