As the heads fell to the ground, the onlookers cheered one after another.

And what Zhou Xian heard in his ears was more of the words of gratitude of 'singing praises to the Lord Qingtian'.

"Chitose, the thief has been punished, these belongings?"

Xu Xianchun asked Tao Zhihuan what to do with the gold and silver that he brought out.

Zhou Xian said: "All of them will be confiscated, exchanged for food, and distributed to all refugees in Xincheng when the time comes." ”

"Yes!"

Zhou Xian then rode into Xincheng.

The city was already in shambles.

The streets and alleys are scattered and orderly, and the houses are empty.

The rest of the old people who are old are obviously unwilling to run away again.

They stood in front of the empty door with indifferent faces, waiting for the end of their lives.

Three days ago.

The information that the Mongol cavalry attacked the border town of Datong has been spread to the entire Xincheng people.

Two days ago, they heard that the 52 forts in Datong were almost dead in name.

The enemy's iron cavalry approached Yanmen Pass, and it seemed that they were about to hit this side.

Since then, the order of Xincheng has been completely disrupted.

The military presence here is gone.

The servicemen also ran out.

When asked about Tao Zhihuan, this old bastard doesn't know anything.

Zhou Xian was even more puzzled by the war situation in the north.

The saddest thing is that he has the elite of the Ming Dynasty to turn the tide.

But all the border officials are blocking him, and even everyone is passing on false news for their own selfishness.

This Da Ming who came to the end of the period is really difficult to bring.

Now Zhou Xian is even more uncertain, did the Mongolian cavalry defeat Yanmen Pass?

If you hit it, then you have to re-plan it.

And then the northwest region of the Ming Dynasty will be completely out of control.

All in all, the weekly line has lost the need to defend in Xincheng at present.

There is no food or grass here, and there is no soldier here.

By what fight?

Zhou Xian then led the army out of the city.

In any case, you have to go to Yanmen Pass to have a look.

As Zhou Xian thought, Yanmen Pass is the last barrier in the border town of Datong.

It's pretty sturdy.

In the middle of the night, Zhou Xian entered Yanmen Pass.

If it is said that the Shanhai Pass guarded by the Liaodong Front of the Ming Dynasty is the barrier of the Central Plains and the pass of the tiger.

The Yanmen Pass is the pass of the soul of the entire Chinese nation.

Since ancient times, Yanmen has been the head of the Nine Stops.

It is a battleground for soldiers of all generations.

The people who hold this pass, as long as they are above the normal, can use 10,000 people to control an army of 100,000 or even 100,000.

Because there are six defenses in Yanmen Pass.

The first is the traditional tall wall.

Moreover, the walls were built at an inclination to the outside.

It is simply impossible to break the city by climbing.

You can only rely on ladders.

However, because of the slope of the city wall, the success rate of the ladder into the city is also very small.

At least 100,000 troops would have to pay the cost of 30,000 men to break through the walls and rush to the towers.

This is still the result of the whole army pressing a fierce onslaught.

But is it over after breaking through the outer walls?

No, the real challenge has just begun.

When the enemy enters the city through the outer walls, they will find that they are surrounded by steep walls that are five feet high.

In the middle of the four walls there are three open spaces the size of football fields.

It can accommodate tens of thousands of people.

This is the city of urns.

At this time, the defenders will fire arrows on all sides, and condescending is another baptism.

Fortunately, the stalemate was until the infantry broke through the city gate, and the attacker's strength had to lose another 10,000 or 20,000.

After two lines of defense, there were only 40,000 or 50,000 left of the 100,000-strong army.

At this time, the defenders will retreat to the inner city.

That is, the third line of defense.

The attackers, on the other hand, had to send more troops to conquer them.

If it is increased to 100,000 men, it will attack the inner city again.

then the casualties must be more than half.

And then there's the fourth line of defense, which is Watergate.

Among the nine border towns of the Ming Dynasty, only Yanmen Pass has built a water gate.

The so-called water gate diverts water downstream of the pass, and then uses the water from the downstream to irrigate the land upstream.

This kind of anti-heaven innovation was developed by Li Bing and his son, who built Dujiangyan in history.

Among them, the water city of Yanmen Pass is hoarded with the water of the Yellow River.

The structure of the terraces in the Sekinai is divided into three steps.

Each staircase is a large pool of water with the help of the terrain.

If the attacking side wants to break through the water city, it will have to be drowned three times.

In addition, the cross-section of the water city is small.

Therefore, even if the attacking side has an army of 100,000 troops, it cannot be spread out to attack.

It can only accommodate 10,000 or 20,000 people to attack one after another.

In this way, after passing through the fourth line of defense at Yanmen Pass, the attacking side was once again severely damaged.

The last line of defense is the steep hills on both sides of the pass.

The defenders are in the mountains and forests, and they can easily hide tens of thousands of soldiers.

The result is a dangerous peak canyon.

The attacker wants to pass, and it is another baptism of ten thousand arrows......

This is Yanmen Pass!

In the records of the military families of the past dynasties, it is one of the few military important places in the world where a husband can not be opened.

When Zhou Xian entered the pass, the first thing he did was to let Lu Delin go to the town to guard the dangerous place.

Then let Xu Xianchun inform the defending generals in the pass.

He stood under the city and looked at this Xiongguan that had suffered from military famine in history but remained strong.

A moment later, Xu Xianchun came to report: "Chitose, people are here." ”

Zhou Xian looked back and saw a group of soldiers rushing towards this side.

The man in the lead looked to be less than thirty years old.

He was wearing an old suit of armor, and stepped forward to bow down: "The last general, Zhao Ziyang, see Chitose!" ”

"What is your position?" Zhou Xian asked.

"The last general will join the army in Kannai."

"General Zhao, let's get even." Zhou Xian saw that the armor on Zhao Ziyang's body was rusty in many places.

Whether such armor has protection is still unknown.

However, the abolition of the Ming armament is a foregone conclusion.

It will take time to turn it around.

Especially since the imperial court has just armed the forbidden army and the equipment of Jin Wuwei.

The defenders of the Nine Sides will be heavily armed, and it will take at least two years.

Zhou Xian suddenly felt a little embarrassed for him.

"Xie Chitose." Zhao Ziyang got up.

"How many defenders are there in the Kannai?"

"Back to Chitose, there are still 800 defenders in the pass, all of whom are under the command of the last general."

"Chitose rest assured, they are all elites of a hundred battles, and they vow to live and die with this pass."

For some reason, Zhou Xian listened to some people's bold words and trusted them very much.

But as soon as some people swore an oath, Zhou Xian felt very insensitive.

Perhaps this is the essential difference between a loyal and good general and a corrupt official.

Zhou Xian frowned slightly: "There are only eight hundred defenders left?" ”

"When Jiang Jian, the chief soldier of Datong, wrote to the imperial court, he said that there were 18,000 guards in this pass."

"In addition, there are five thousand logistics personnel."

"In total, there are twenty-three thousand troops."

"Chitose, is that really the case?" Zhao Ziyang's face was shocked.

Obviously, he didn't expect his immediate boss to brag so much about the court.
