Three Kingdoms: I, Ma Su, Only Seek Death

"What the hell is that!!"

When he saw the thing dragged out by the Han army, Sima Yi's face suddenly turned pale.

They were several catapults. Although they were very different from traditional thunderbolt chariots in many places, Sima Yi could still tell that they were catapults.

But the problem is... this is too big!

Even the smallest catapult among them is more than twice the size of a traditional thunderbolt cart. The Han army used dozens of oxen and hundreds of civilians to drag it, and then they could barely move the catapult out from behind the earth wall.

Especially Sima Yi saw the huge rocks being carried behind him, which were several times larger than the largest rocks that the Thunderbolt Chariot could throw. As a rough estimate, a huge boulder would weigh hundreds of kilograms!

Ma Su had been holding it back for two months, and when he had nothing to do, he simulated the design with Master Pu Yuan. After the main business invested a lot of manpower and material resources and designed it all night long, it was a surprise.

That's right, it turns out that the number one siege weapon in the cold weapon era in history is the Huihui artillery!

Since he discovered that Chang'an City's defenses were a bit too strong and that the defender was still Sima Yi, Ma Di immediately thought of using return artillery to deal with the Wei army.

Although the return cannon has shortcomings such as being bulky, inconvenient to move, and very difficult to make. But it cannot be denied in any case that the Huihui artillery is the pinnacle of siege equipment in the cold weapon era.

This kind of catapult basically applies various technologies such as the lever principle to the extreme, making the weight of the catapult reach its peak.

The most intuitive example is that this thing can throw a boulder weighing 150 kilograms 300 steps away!

Such an instrument would have been a powerful weapon even in the Ming Dynasty, let alone in this era when slinging equipment was not included in the category of sieges.

Ma Su gave Sima Yi a big surprise!

It was precisely because of this that the Han army kept piling up forts in Weinan and built earthen walls that stretched for hundreds of miles with sand and water.

If the Shu army had built this catapult openly, the Wei army would have gotten the news a long time ago. Chang'an City was not so short of manpower, and Sima Yi could still urgently build a temporary wall in the city to prepare.

Although the Huihui Cannon is powerful, its range is not as high as the 800-step range of the Thunderbolt Chariot. If Sima Yi built a large number of second sections of walls in the inner city, even if they were temporary piles, the offensive of the Han army would be greatly delayed.

But now Ma Su no longer has this worry, because even if Sima Yi wanted to, he didn't have the manpower to repair the city wall now. Because the earth wall built previously diverted Wei Jun's attention, because all of Wei Jun's manpower in the past two months was devoted to building the Thunderbolt Car.

But in fact, that earth wall was not prepared for a long-term confrontation at all, but was used to cover the assembly of the Han army and the construction of return artillery!

After seeing all this scene, Sima Yi quickly reacted. As an old artist for many years, he also figured everything out in a very short period of time.

He was fooled by Ma Su!

Ma Su's goal from the beginning was to storm Chang'an. He was not here for a long-term confrontation at all! But because of the cover of that damn earthen wall, he didn't figure it all out until the moment of the Han army's showdown!

Is it really still too late?

"The whole army goes out to fight! Destroy that catapult for me at all costs!" Sima Yi quickly thought about everything and made a judgment in an instant.

Although he didn't know what the catapult was like, Sima Yi still knew Zhuge Liang and Ma Su's master and apprentice. They won't reveal their trump card until they are absolutely sure. When you see his trump card, there is a high probability that he can beat you.

So now we must not let the Shu army push that catapult to Chang'an City! The catapult must be destroyed before the Shu army launches a bombardment on the city head!

The generals did not react to Sima Yi's order for a while. However, as Sima Yi turned his head and gave them a death stare, everyone quickly realized the seriousness of the matter.

The usually steady Governor was so panicked now, something was probably going to happen!

Under Sima Yi's urgent order, the troops that had been assembled in Chang'an City responded immediately. Guo Huai, Hu Zun, Sima Shi and other generals all put on armor and mounted their horses to lead the troops into battle.

Suddenly the gate of Chang'an opened, and a large number of Wei troops filed out and rushed towards the Han army.

"Prime Minister! Look what I said! Sima Yi is in a hurry!"

In the Han army's camp, Ma Di stood next to Zhuge Liang's four-wheeled chariot, pointed at the movements of the Wei army with a smile, and said to Prime Minister Zhuge.

"How can we not be in a hurry?" Zhuge Liang himself came to the earth wall in a four-wheeled vehicle at this moment. Looking at the emergency situation of the Wei army, he couldn't help but smile.

"Youchang, your machine skills have actually improved to this point... It's a shame that you can imagine such a mysterious instrument."

"I understand a little! I understand a little!" Ma Su didn't dare to brag too much about this, after all, he just learned from it.

"But it seems that the Wei army is now out in full force and planning to destroy our Chang'an artillery. And this is probably the most critical battle for Chang'an. Look, Prime Minister..."

With that said, Ma Su pointed to the Zhuge Liang version of Luban Lock 7.0 in his hand without leaving any trace.

Although according to his opinion, it was not difficult to pry open this lock, Ma Su still did not have the courage to pry the lock in front of the prime minister.

"You kid, you'll feel uncomfortable if you don't fight for a while..." Zhuge Liang felt helpless, pondered for a while, and waved his hand calmly. Then Zhuge Liang's soldiers stepped forward and helped Ma Su open the lock.

"This will never happen again!"

"Okay! Prime Minister! Thank you for your trust, old man!" Ma Di was overjoyed, but was immediately slapped by Zhuge Liang's feather fan.

"But I have to remind you that after spending so much manpower and time on this plan for you, if you fail to capture Chang'an..."

"You can twist off my head and use it as a chamber pot!" Ma Di promised, patting his chest and picking up the military flag.

"The whole army is dispatched!"

Ma Su had expected that Sima Yi would be unable to sit still and mobilize the entire army. After all, seeing as his bastard shell was about to be shattered, there would be trouble if he could still sit still.

Therefore, in order to prevent the Wei army from jumping over the wall in a hurry, the main force of the Han army had completed its assembly under the cover of the earth wall within two months. At this moment, with Ma Su's command flag waving, the Han army soldiers who were already ready to attack quickly rushed out from behind the earth wall!

"Recover Chang'an! Return the old capital!"

"Recover Chang'an! Return the old capital!"

"Recover Chang'an! Return the old capital!"

Amidst the shouts, the Han soldiers quickly rushed forward and protected the returning artillery in the middle.

Their mission is to withstand the Wei army's final counterattack and push this big killer to the city of Chang'an.
