Of course, as precarious as the state of Chu, there is also the state of Sheng.

On the eighth day of the first month of March, Cangguo questioned Sheng Guo on the grounds that Sheng Guo had violated the covenant.

Emperor Sheng was frightened, and hurriedly sent someone to Cangguo to explain, and then Emperor Sheng Min Lei went to Cangguo in person to explain the misunderstanding.

There was no surprise that Emperor Shengguo was humiliated when he entered Cangguo, and under the leadership of Shangshu Ge Lie of the Ministry of War, he went to the location of the Xuanwu Army and watched a big military parade.

Zhu Xi, the generalissimo of the Xuanwu Legion, who learned of this, immediately understood the meaning of the imperial court, and immediately dispatched 50,000 people to set up a formation outside the station.

As a group of people at the top of the Sheng Kingdom, of course they know how powerful their own army is, and now when they compare with the army of Cangguo with their own eyes, a world of difference is presented in front of them.

Is such a large team really owned by Cangguo?

Sheng Huang Min Lei couldn't help but secretly exclaim in his heart, what happened in five years, when Cangguo was still 200,000 troops, Sheng Guo was already powerless to resist, and now there are millions of troops, what will Sheng Guo use to fight?

Right now, the only Jin Kingdom that has been pinned on hope is busy invading Chu in the south!

Emperor Min Lei of Shengguo complained bitterly in his heart, and secretly scolded the Emperor of Jin for attacking Chu at this time, because even he didn't think that Jin State's attack on Chu was a worthwhile thing, but it was better to come one by one, first eliminate the threat under his nose, and then slowly plot.

At least, if the Sheng State is swallowed up by the Jin State, the monarchs and ministers of the Sheng State may still have a good old age, but if they become the captives of the Cang State, it is better to live than to die.

"What's that?"

Suddenly, Min Lei saw more than a dozen very tall wooden frame cars launched from the rear army, and couldn't help frowning.

Cangguo has always won by surprise, and this kind of thing that he has never heard of at all has attracted his attention.

On the side, Han Tong stood on the commander's chariot and said proudly: "This is the latest siege weapon of my Cang army-catapult, what does Your Majesty think?" ”

When Min Lei was still puzzled, he saw a group of soldiers, rolling huge stones and putting them on the catapult.

"Boom—"

A huge stone, in a perfect arc across the sky, landed on the ground a mile away, and a huge sound rang out.

The dust is flying, rolling like thunder.

Min Lei was taken aback, how could such a bulky stone, at least a few hundred catties, be thrown into the sky?

"Boom—"

"Boom—"

Then, there were two loud sounds, and one of the stones smashed against a wall in the distance, and the high wall made of blue bricks collapsed at once.

The monarchs and ministers of Sheng Guo couldn't help but break out in a cold sweat, and the eyes that looked at the siege vehicle had completely changed.

From doubt, to fear.

In the face of such a monster, what role can those walls of Shengguo do?

I'm afraid that if I can't take a few hits, it will collapse, right?

For a long time, the monarchs and ministers of Sheng Guo have understood a truth, they can't beat Cangguo in a head-to-head confrontation, but Sheng Guo can still do it if they are cowering in the city.

Among them, Prime Minister Zhu Lixing is a supporter of this proposition, and listed the facts that the reason why the Dong Kingdom was driven straight into by the Blue Dragon Legion and the White Tiger Legion and directly attacked the imperial city was because the main force of the Dong State army was completely lost, and there was no strong army to defend the city.

This thought has always supported Sheng Guojunchen, and it is precisely because of this that it has given Sheng Guojunchen some psychological comfort.

For this reason, in the past two years, Sheng Guo has never relaxed the repair of the border city, even if the soldiers' weapons are outdated, they have not given up the reserve of bows and arrows, etc., everyone believes that after the loss of Cangguo's cavalry advantage, it is impossible to take advantage of the situation that more than 500,000 regular troops of Sheng Guo defend the city.

But what I saw today directly destroyed the faith in the heart of Emperor Min Lei of Shengguo.

When the city wall collapses, what else can Sheng Guo defend it?

Defending the city is just an empty word.

On the same day, after Sheng Guo Min Lei returned to the post house, he was depressed and his face was pale.

On the second day, he fell ill in bed.

This can make Yang Mu embarrassed, even if the two countries that are at war, they have a tradition of not beheading, if the emperor of Shengguo dies of illness in Cangguo, then many of the previous arrangements will be in vain, the unrighteous name of Cangguo is a backlash, which country can still rest assured to make an alliance with Cangguo in the future?

This is something that even the Jin Kingdom didn't dare to do at the beginning, let alone the Cangguo.

Therefore, he could only ask the Ministry of Medicine to summon the imperial doctor to treat the emperor.

I have to say that Cangguo's current medical water products have thrown off several streets in various countries, and some basic diseases have basically no problems, with the popularization of some medical and health knowledge, not to mention other diseases, even the infant mortality rate in Cangguo has been much lower in the past two years.

After cultivating for a few days, he finally sent this emperor of the Shengguo back.

Yang Mu also breathed a sigh of relief, the foreshadowing work was basically done, the game between countries has no women's benevolence, either you die or I die.

After listening to Zhu Xi's letter, he became more confident in this battle.

In this battle, his biggest confidence is trebuchet.

The trebuchet, as an ancient combat weapon, has appeared before this, and it has made a contribution in the previous war against Zheng Guo.

But it was a very simplified catapult, far from the point of collapsing the city walls.

At first, Yang Mu didn't understand it either, but it wasn't until he stumbled upon an introduction in a bunch of books that he suddenly realized.

Catapults have existed in China for thousands of years, and if it weren't for the appearance of gunpowder weapons, I don't know how long they would have been making waves on the stage of history.

At the beginning, there were two kinds of cannons on chess, one next to the stone word and one next to the fire word, which later evolved into two identical cannons, and from a professional point of view, the "cannon" next to the stone word is the trebuchet.

China's written trebuchets first appeared in the Spring and Autumn Period and the Warring States Period, and the first large-scale use of trebuchets in the history of Chinese warfare should be Li Xin's attack on Chu, the Chu army secretly prepared a large number of trebuchets, when the Qin army crossed the river suddenly launched at the same time, countless sharp stones smashed into the Qin army like hailstones, so that the 200,000 Qin army was completely defeated, seven captains were beheaded, and Li Xin also committed suicide due to defeat.

And the most well-known is recorded in the "Chronicles of the Three Kingdoms", Cao Cao and Yuan Shao fought in Guandu, Hebei, Yuan Shao's archers and arrow towers once had the upper hand, and the suppressed Cao Jun had to put a shield on his head and hang the pot lid on his hips when he went out to the toilet.

Later, the strategist Liu Ye presented the drawings of the trebuchet, and also gave a loud name called "Thunderbolt Car", Cao Jun made it according to the law, and built a large number of trebuchets, which turned the tide of the war.

The catapults of this era are the kind before Cangguo.
