"By the way, you said earlier that your fifth brother was imprisoned in Daxing City Prison?"

Chu Zhen asked Li Shimin.

He checked Li Shimin's fifth brother just now, and found that his name was Li Zhiyun, this kid was more unlucky, and when Li Jiancheng and Li Yuanji fled back to Taiyuan, he was left behind.

After Li Yuan's father and son raised troops, Li Zhiyun was captured and returned to Daxing City, and was killed by the criminal department Shangshu Yin Shishi in Daxing City soon after.

Why was Lee Ji-yun left behind?

Chu Zhen has reason to guess that Li Jiancheng and Li Yuanji are trying to use him as a trick so that the brothers can escape, and Li Zhiyun is a concubine, and if he dies, he will die.

"Yes."

Li Shimin's expression was a little gloomy, as if he knew what Chu Zhen wanted to ask, and sighed: "When my brother and Yuanji fled back to Taiyuan, the fifth brother was left behind, I asked the two of them, and they said that the fifth brother was too young to travel long distances on horseback, so he stayed. ”

"Li Zhiyun was 14 years old when he was killed."

Chu Zhen said, looking at Li Shimin.

Sure enough, this young general, who values brotherly feelings, frowned suddenly: "Killed? This year? At the time of the siege of Daxing City?! ”

At this moment, the fifth brother is being taken hostage by the defenders in the city, and it is impossible for the Li family father and son to give up Daxing City for the sake of a Li Zhiyun, once they attack the city, the fifth brother will definitely die.

Why did the elder brother and Yuanji leave the fifth brother behind......

Li Shimin's right fist clenched unwillingly.

"How are you going to take Daxing City?"

Chu Zhen changed the subject.

The details of the Chinese history books are very detailed, but the omitted places are really maddening.

For example, with the exception of "Zuo Biography", there is no history book that describes a war in detail.

During the war, the terrain, the direction of the river, the specific number of our troops, what armor they wear, how to place the array, where the reinforcements are ambushed, where the enemy troops come from, and so on.

There are also some descriptions of chariot graphics in the left pass, and after the left pass, there is nothing at all, all of them are how many years and months to go out of the army, how many people have been killed, at most plus the description of the division of thousands of troops, and the rest is gone.

"Defend the big city and fight in the wilderness, defend the lonely city and sit and wait to die!"

Speaking of military affairs, Li Shimin regained his self-confidence and said categorically.

"A good defender of a big city will fight in the wilderness!"

Zhu Yuanzhang, who had been silent, slapped his thigh excitedly at this time, "This sentence is well said!" Just one sentence to say the root of defending the city! ”

“？”

Li Qingzhao and Lin Daiyu, who didn't know anything about men's affairs, glanced at each other.

"What do you mean?"

Chu Zhen asked with a smile, he didn't know how to fight.

When he looked at the Three Kingdoms, he was puzzled, why did the generals who defended the city always like to go out of the city to fight? There was also plenty of food and grass in the city, so there was no need to go out at all, but there were still many generals who were lured out of the city and ended up being dumplings.

Li Shimin smiled slightly and was about to speak.

"Wait."

Chu Zhen stopped him, pointed to the camera, and said: "This thing is called a camera, it can pass your portrait to other people, they are also listening to our conversation, and now they want to see the demeanor of Li Shimin, Taizong of the Tang Dynasty, what do you mean?" ”

"Let Mr. Chu decide."

Li Shimin had nothing to say.

He probably knew that this was the afterlife, but there were many things here that he couldn't understand, Mr. Chu was in charge of these magical objects, where could it be ordinary people?

Chu Zhen nodded, glanced at the barrage, and the audience was already boiling, shouting faster.

Chu Zhen quickly got it right, connected the drawing board and projector, and shouted to Zhu Yuanzhang again: "Help me close the curtains...... Little Lady Li, Miss Lin, you help me pull the curtains over there. ”

Zhu Yuanzhang: "......"

He carried the emperor in a dignified manner, and he was actually instructed to pull this curtain?

How do you get this thing?

Li Qingzhao and Lin Daiyu got up and went to pull the fabric hanging by the window, and they easily pulled it.

Soon, the house was darkened.

Chu Zhen turned on the projector, and a white pillar of light shot out from a square box, and the light hit the wall, forming a brilliant and colorful picture, which shocked the four ancient people in the room.

Li Shimin, in particular, was amazed in his heart and was even more respectful to Mr. Chu.

He has also seen many cultivators in Taoist temples, but whether it is chanting Buddha or chanting scriptures, they are far inferior to the miraculous images that Mr. Chu casually shows!

"This thing ......"

Zhu Yuanzhang's expression was shocked, and he doubted his judgment for a while.

Li Qing looked at the projection screen and couldn't help but say, "Chu Langjun is really a god!" ”

Lin Daiyu pursed her thin cherry lips and did not speak.

She didn't care much about this, she was only curious about why Uncle Chu did this.

"Are you ready?"

Chu Zhen deliberately disguised and said: "The Tang Emperor Li Shimin appeared for the first time and besieged Daxing City!" ”

The camera turned and focused on Li Shimin, who was wearing Xuanjin armor.

The young general appeared in Chu Zhen's live broadcast room for the first time.

Instantly caused a piece of "666"!

"Wow, I have the demeanor of my Erfeng! So handsome~~ What is the anchor's name? I'm going to pay attention to one! ”

"The anchor is awesome, this set of armor has made a lot of money, it is much more gorgeous than those live broadcasts in the film and television city!"

"Tsk, it's still a full-body armor, this one who plays Li Shimin is not simple, and the momentum is very hard!"

"No one notices that it's Emperor Hongwu sitting on the sofa in the corner? Hahaha, the anchor is not professional, hurry up and let him stand up and play against Li Shimin! ”

"What about the two beauties? Who are Mrs. Li and Miss Lin? ”

"The anchor asked Li Shimin to say two lines! Didn't you just talk about it? ”

The barrage was so loud that Chu Zhen had the illusion that he was on fire, but in fact, when he looked at the live broadcast room, the popularity was more than 10,000.

"Let's go!"

Chu Zhen was shocked to shoot the wood, the standard starting style, and then picked up the stylus and drew a circle in the center of the drawing board, in which the word "Daxingcheng" was written.

Then draw two lines in the north of the city, add a few splashes, and write Weishui.

To the south is the Qinling Mountains.

"Where's Jingyang?" Chu Zhen asked.

"Probably here. Xinfeng is here, Chang'an is here, Tongguan is here, and Zhushui, Weishui, and Jingshui are such trends......"

Li Shimin saw Chu Zhen's thoughts at a glance, pointed at the projector with his sword, and instructed Chu Zhen to draw a map one by one.

Moreover, what he said was far more detailed than Chu Zhen asked.

What are the mountains, wide canyons, small streams, where are the villages, whether the mountain roads can pass, how high the weeds are by the rivers of the army, whether the ambushes can be laid, and so on.

So much so that Chu Zhen gave up directly, and only drew a little.

Li Shimin smiled slightly, took the initiative to pick up the previous topic, and said: "The so-called everyone who defends the big city must fight in the wilderness, which means that once the big city is besieged, the defenders in the city must find the right time to go out of the city to counterattack, why?" It all started with how we attacked the city. ”

Li Shimin pointed at Jingyang with the hilt of his sword, "After I occupy this place, I will leave two thousand soldiers and horses to garrison, as a back road, my brother built the ...... that now guards Tongguan."

That's twenty minutes.

Explain all the siege essentials of ancient times!

Where to surround it, how to surround it, where the soldiers should be stationed, how to trap the men and horses in the city, cut off the way for reinforcements, and how to dig fortifications to prevent the soldiers and horses in the city from rushing out.

The nearest garrison must not be too far from the city gate, otherwise it will not be able to counterattack the people rushing out of the city in time, and it should not be too close to prevent it from being scattered at once.

In addition, the construction of siege equipment should begin immediately, and it should be rolled out as soon as it is finished to deter the defenders in the city.

There is also digging up the river so that the people in the city cannot get water, of course, this is not effective for Daxing City, there are too many rivers nearby.

After listening, everyone in the live broadcast room was dumbfounded.

It seems to be a little professional!

When he was talking just now, Li Shimin pointed to the map with the hilt of his sword, and his momentum was extremely strong, as if he was pointing at the front of his soldiers, and thousands of soldiers fought bravely to kill the enemy, and the enemy fled in horror.

Half a day.

"What are the siege equipment?"

Chu Zhen asked with a smile again.

Li Shimin immediately began to talk again, he didn't know how to make them, but he was very familiar with what they were like.

After the lecture, he added how to patrol at night to guard against reinforcements in the city and possible arrivals.

Hearing this, there is nothing else on the barrage except "6"!

"I watched the TV series and thought that the ancient siege was to surround the city, but I didn't expect the siege to be to hold the nearby passes and trap the people in the city!"

"No wonder Li Shimin said that defending the big city must fight in the wilderness, under such a siege, the morale of the defenders in the city can only decline day by day, and if you don't fight, you will die."

"There are still many civilians in the big city, and once they are trapped for a month, rumors will spread and morale will fall faster."

"After listening to it, I just want to say that Li Shimin's siege is really ruthless!"

"Where did the anchor find the actors? It's too professional, isn't it? ”

Chu Zhen glanced at the big curtain, raised his head and was about to speak, only to hear Zhu Yuanzhang stand up suddenly, look at the young man in armor with burning eyes, and shouted:

"What a Tang Emperor Taizong Li Shimin!! This siege is really wonderful! ”

He completely believed that the young man under eighteen in front of him was Li Shimin!

Except for Emperor Taizong of the Tang Dynasty and himself, no one else could have such a subtle method in leading the army to fight!
