Tibet

Three days have passed in the blink of an eye, and the actual combat training in the imperial city is still in full swing.

In the morning, Li Ye came to Xineiyuan. Just as Li Ye himself attacked Chang'an City from the north, he was also more worried about the defense of the palace city in the north. The walls of the palace city were actually exactly the same as the other three walls, all three feet tall. feet high, the city walls are tall and strong, and the moat is three feet wide.

But the north side is relatively flat, which can open up the battlefield, and there are many city gates. In particular, Anlushan's army can dismantle the palace pillars of Han Chang'an City and use them as battering rams.

Although he wants to get rid of these hidden dangers, it will take at least a month for Li Ye to completely demolish Han Chang'an City now. Moreover, even if Han Chang'an City is demolished in time, there are still other county government offices. It is still relatively easy to find raw materials for the battering ram. This It was the first time in the more than 100 years since the founding of the Tang Dynasty that Chang'an City had become a battlefield, and he was unable to completely strengthen the walls and clear the country.

The trees in the East Inner Garden have been cut down, and the trees in the West Inner Garden are about to be cut down. The entire outside of the palace has become bare.

At this time, Pei Xiu said in a deep voice: "Your Highness, I have two suggestions for you!"

Li Ye nodded, "You say it!"

"Our kerosene weapons are powerful, but the other side also has gunpowder weapons. Even if its explosion damage is not great, the recruits don't know it. Therefore, we need to conduct drills for the recruits to prevent Juntian thunder to prevent them from being injured by poisonous nails. This is one.

Secondly, the enemy will definitely attack with fire. I suggest setting up a fire-fighting team in the militia to extinguish the fire in time. "

Li Ye said happily: "These two suggestions are very good. You will be responsible for the drills to prevent Juntian thunder. I will let Zhang Ping be responsible for setting up the fire-fighting team!"

Pei Xiu nodded, "I'll make arrangements right now!"

Pei Xiu bowed and left.

Li Ye then led a group of people on horseback from the city wall to Qujiang Pond in the southeast of the city. This was also a weak defense point. Although there was a tall city wall, the waterway into the city was wide, and the enemy could enter the city by water.

And Li Ye is a little worried that the weather has obviously become very cold in the past two days. Long icicles began to appear under the eaves, and the ice on the river is no longer thin ice, but has become thicker. Once the water in Qujiang Pool freezes Indeed, the enemy can directly enter the city from the ice.

The general responsible for guarding the gap in Qujiang was Guan Pei. He said to Li Ye: "I have asked the surrounding residents that the ice surface of Qujiang Pool can be skated in winter. Now that the weather is getting colder, I am afraid it will freeze soon." ”

"Is it freezing now?" Li Ye asked.

"We tested it yesterday, but it hasn't completely frozen yet. We haven't tested it yet today."

Last night it was at least ten degrees below zero. After a night, I'm afraid the situation has changed again.

Li Ye immediately ordered: "Test now!"

Guan Pei immediately arranged for soldiers to conduct experiments. Several soldiers hit the ice with hammers more than a dozen times before the ice cracked. Then a dozen soldiers pushed a wooden boat into the lake. , walked two miles, and pushed the boat back again. Li Ye's heart sank, and the lake was ready for people to leave.

The entrance to Qujiang Pond is thirty feet wide. How can we defend against such a wide gap?

Guan Pei bowed and said: "Even in humble positions, I gathered soldiers to think of a way. Some people said that they would pile up sandbags, and the defenders behind the sandbags would use dense crossbows to deal with the enemy. Even with shields, they can still penetrate."

Li Ye nodded, "This method is okay, but the enemy will have countermeasures to defend against arrows. Do the soldiers have any other ideas?"

"Some soldiers suggested setting fires and burning them with large logs to form a wall of fire."

This method is also possible, Li Ye smiled and said: "Keep talking!"

"There are also holes drilled densely on the ice, like a horse pit, to deal with cavalry, or spears inserted diagonally, just like the spear formation outside the military camp."

There are really three Zhuge Liangs, but one is the cobbler. All these methods can be implemented.

At this time, Sima Su Zhen offered his advice: "Your Highness, I have an idea!"

"Su Shijun, please speak!"

Su Zhen laughed and said: "Beizhi is from Chang'an. I often came to Qujiang to skate when I was a child. I remember when I was twelve years old, I was pierced by a wooden thorn on the ice and lay in bed for a whole month, so Beizhi thought it could be used." To quench the poisonous thorns, pour hot water on the ice at night and sprinkle a large amount of poisonous thorns. After dawn the next day, the thorns will be frozen in the ice, but the spikes will be outside."

"Wonderful! This is a great plan." Everyone clapped and praised.

Perhaps inspired by Su Zhen's plan, Li Ye suddenly thought of a good way to freeze hot water.

He laughed and said, "I have a good idea!"

Everyone looked at him, and Li Ye smiled proudly and said: "Pilt it up high with bags of sand and earth, pour water on it repeatedly, and freeze it into an ice wall, making it extremely strong. I wonder how they can attack the city?" "

"good idea!"

Su Zhen smiled and said: "Then simply pour water on the outer surface of the entire city wall and freeze it into an ice wall. The enemy's siege ladder will not be stable."

Li Ye immediately concluded: "All of these plans can be implemented, especially the poisonous Tribulus. We summon craftsmen to make millions of them, quench the poison and scatter them outside the city."

Su Zhen was a little worried and said: "Your Highness, this will hurt ordinary civilians in the future!"

Li Ye thought for a moment and said, "Then sprinkle it on the moat!"

On the seventh day after the capture of Chang'an, a thirty-man Tang Army scout team hid on a hill on Jingyuan Road, watching the Jingyuan Road two miles away. It was still about fifty miles away from the exit of Jingyuan Road. Once The main force of the Yan Army heading south will inevitably pass through here.

The leader of the scout team is General Zhang Dian. His mission is to provide early warning after discovering the enemy's main force.

"General, do you think Chang'an City can be defended?" a soldier asked worriedly.

Zhang Dian smiled and said, "You are from Chang'an. Don't you know whether you can hold on?"

The soldier sighed: "Since my great-great-grandfather, there has been no war in Chang'an City. The last time they attacked Chang'an was the Sui Dynasty! People in Chang'an have never seen a war. I don't know if they can hold it."

Another soldier said: "Didn't An Lushan attack Chang'an City some time ago?"

"Anlushan was not attacked. The emperor ran away and handed over Chang'an to Anlushan. No war broke out."

Zhang Dian smiled and said: "No one knows whether we can hold it, so it means that it is possible to hold it. His Royal Highness, King Lu, has experienced hundreds of battles in the Western Regions. I think we can definitely hold it."

At this time, there was the faint sound of horse hoofbeats in the distance. Everyone quickly looked towards the official road and saw another group of Yan army cavalry rushing towards them on Jingyuan Road, about twenty people.

From morning to now, this is the ninth cavalry squad. They should be enemy outpost spies. According to usual practice, the main enemy army should appear soon.

"General, look!"

One soldier pointed north and shouted: "The army is coming!"

Then a mighty cavalry came down. The flags of the team in front were fluttering and they were menacing. The black cavalry could not be seen at a glance. The team was not fast, but at least it numbered more than 10,000 people.

Zhang Dian decisively ordered: "Release the letter eagle!"

The soldier immediately tied the letter tube to the eagle's leg and opened the eagle's cage. The eagle flew up and circled twice in the air, then flew slowly towards Chang'an.
