Let you be a faint king, and you have unified the six kingdoms?

"The climber kills!"

"Throw bombs in the direction of the city gate!"

"Hot air balloons go up! Send messages with signal arrows!!"

…………

Yang Su woke up suddenly.

Sitting up straight all of a sudden, the pain from his body didn't even make him snort.

The guards outside entered immediately.

"How's the battle going?" Yang Su covered his head with a stern expression.

"General He Ling has taken over the command!" The guard replied, "We are still fighting!"

"How long have I been in a coma?"

"An hour and a half!"

"Thank you for your hard work..." Yang Su immediately got up, put on the battle armor, and walked towards the city.

He soon saw He Ling.

"Well done." Yang Su said to He Ling.

"It should be!" He Ling wiped the blood on his face.

Yang Su immediately re-examined the battlefield.

There are rockfalls all over the walls.

Wei Jun's catapult throws it really accurately...is it a special catapult?

These stones put a lot of pressure on the defense.

"Where's the hot air balloon?" Yang Su asked.

He Lingdao: "It has been lifted into the sky, and information is constantly being sent back."

"The location of the catapults has been determined, let the hot air balloon come back, equip the bombs, and blow up those catapults for me." Yang Su ordered.

Immediately someone went to do it, and soon the hot air balloons started descending.

"But... the accuracy seems not enough..." He Ling said.

It's not that he hasn't thought about it.

But if the hot air balloon rises too high, the accuracy will drop, so more bombs are needed to hit the target.

"Wei Jun's catapult is too powerful. Get rid of this first." Yang Su said.

"Then if the Wei army uses siege vehicles to break through the door, our bombs may not be enough!"

"Don't worry. I have fixed the city walls and gates with cement."

Yang Su said.

So far, He Ling didn't speak anymore, but silently studied Yang Su's commanding art.

Chapter 185 The thirteen princes who died of depression, Luo Zhi, the increasingly fierce battle on the front line

2030 years.

Department of History, Tsinghua University.

"In Kangzhe's three years, Wei State changed its strategy. From a full-scale attack to a focused attack, Feng De's six-line strategy went bankrupt." The history teacher said.

"At the same time, Emperor Luo Lin went to Jiangnan again."

"Let's take a look at this question first, and use your mobile phone to answer it."

A question appears on the screen.

And this question also appeared on the mobile phones of all the students.

Topic: What benefits did the emperor Luo Lin bring to Jiangnan for the third time?

Immediately, some students started typing.

After a while, the students finished answering, and the intelligent AI directly selected the key points for scoring.

The history teacher took a sip of tea and saw the average score.

A 6-point question with an average score of 4.6.

"There is nothing to say about this kind of link. The history department has a lot to memorize. And if many words are wrong, the meaning will be completely different. If you want to get a good grade, you have to memorize well."

The history teacher tapped the big screen.

Answers began to appear on the big screen.

1，震来，自.小！说。群:9:8"0'2。0；5′8，5:6慑世家，稳定国内局势。

2. Inject the money in the internal treasury into the private sector to drive the economy.

3. The prestige of the imperial court has risen.

4. Master the sentiment of the people.

5. Promote the development of festival culture.

6. Eliminate the political hidden dangers of the thirteen princes.

"I took a look, the main reason is that you have not achieved the sixth point. Everyone is very smart, and I have memorized the problem-solving methods. Therefore, it is best to get 5 points for this kind of topic, and half of the students did not get it. Cultural points."

"I'll say it again. Solve the problem according to the three axes in two dimensions."

"The first dimension is the class dimension. In the civilian class, in the aristocratic family class, in the royal and noble class."

"The second dimension, the national aspect. From the cultural level, from the political level, from the military level."

"The sixth point of this question is more difficult to answer."

"The answer came out... there are three classmates, just choose one at random and answer it."

Soon, a rather quiet girl stood up.

"I know the sixth point because there was an episode during the emperor's third trip to the south of the Yangtze River. That is, he met the thirteen princes. After this meeting, the thirteen princes left the political center." The girl said.

"Yes!" The history teacher nodded.

Then the figure of the Thirteen Princes appeared on the big screen.

"The thirteenth prince, Luo Zhi. A prince with a strong sense of rebellion, and he is also very young. He is only in his 30s."

"Why do you say that he left the political center after the emperor went to Jiangnan for the third time?"

"Simple because he's not even in the country anymore."

"Historical records show that the emperor said to the thirteen princes at that time: I don't like ministers who do nothing."

"The thirteenth prince is numb all over, and he is very scared, for fear that the emperor will cut him off with his backhand."

"After he went back, he thought about it."

"Continue to govern his fiefdom, that means nothing has changed, and there will be a dead end."

"In the end, the thirteenth prince took out a lot of money to order a large number of ships, formed a fleet, and decided to do one thing."

"What is it? Proclaim the greatness of Daqian!"

"But in fact, historians of later generations basically believe that Luo Zhi probably went back to his old business."

The screen changed and turned into a world map.

Then focus on the Southeast Asian archipelago region below.

"After the thirteenth prince arrived in this area, there were more pirates. Then the thirteenth prince recruited a representative to suppress the pirates."

"In this area, Dagan has gradually gained influence."

"Do you know what happened to Luo Zhi?" The history teacher changed the topic.

The students shook their heads.

"Actually, what he did did not satisfy the emperor. Even if the thirteenth prince is far away from the political center, he is quite dissatisfied with it, and he wants Jin Yiwei to kill him several times."

"But Luozhi is located in a remote place, and the Jinyiwei accompanying him...missed!"

"Luo Zhi was completely hopeless at the time. In the end, he confessed what he had done, and then went into self-exile and became the emperor of the land in Southeast Asia."

"And the emperor rejected his proposal, did not admit that Luo Zhi was exiled, but did not send troops to destroy Luo Zhi. This move gained the name of benevolence at the time."

"After Luo Zhi heard the news, he was afraid that the powerful army and sailors would come to kill him. In the end, he was under too much mental pressure and died of depression within a few years."

The history teacher finished.

There was a burst of emotion in the hearts of the students.

Because of too much mental pressure, I died of depression... I was too scared to go back to work.

Is this the sense of oppression that belonged to the emperor in that era?

They have nothing to say about the emperor's actions. In fact, it is a typical struggle for imperial power.

There is no reason to fight for imperial power, it is bloody and cruel, like the emperor and Luo Zhi are actually quite gentle.

"If the thirteenth prince is older, or if his personal ability is stronger, and then he is extremely loyal. Then maybe the emperor will treat him completely differently." The history teacher also said with emotion, "On the other hand, the fourth prince, he got The great emperor's important use, sealed the land, and gave him great power. The fourth prince also gave him his return: Qidi Dazhi, and two tax laws."

"Looking at the thirteenth prince's southward move, in fact, it didn't drive any economy at all. Although the national prestige of Daqian was publicized, it is completely incomparable with the fourth prince."

"Incompetent, ambitious, disloyal, and young. He is only in his 30s. Most emperors ascend to the throne at this age."

"It can only be said that the thirteenth prince, who is a dish and loves to die, ended up like this, which is reasonable."

The history teacher finished talking about the Thirteen Princes.

Then he said: "Now let's move on to the battle."

"On the southern front of Yandi, the Wei army and the Qian army entered a great battle. According to historical records, this battle..."

"Blood in a river!"

…………

"retreat!!"

Qianguo, the southern front of Yandi.

Yang Su roared angrily.

There are too many armies.

the most important is……

A big hole was pierced through the city wall, and now the Wei army is pouring in in large numbers.

After learning the news, Yang Su ordered the army to retreat without hesitation.

"Damn it, I didn't expect this garbage city to be strengthened by cement or broken."

"No...you can't blame the city, it's because there are too many trebuchets and they are too powerful."

"so troublesome."

Although some catapults were blown up.

But the impact of the time lost at the beginning is still too great.

Yang Su had to admit his mistake, and then choose the most suitable tactical decision.

this battle.

Wei Jun Casualties

More than 500 people were killed, but countless were wounded, thanks to the advantages of equipment and city defense.

In the case of similar elite levels of soldiers on both sides, the battle loss ratio was two to one.

But it is a pity that five cities were lost, many of which were battlegrounds for military strategists.

On the strategic level, the army suffered a disadvantage.

The defensive line was forced to retreat.
