Since Zhang He led his army to Jieting, Liu Feng had been waiting for the Wei army to launch an attack on the Han army camp.

However, for several days in a row, the Wei army in the large camp on the opposite side has never launched an attack.

The silence of the Wei army did not make Liu Feng lower his guard, but a worry faintly appeared in his heart.

Liu Feng speculated that Zhang He was planning a big event.

Liu Feng did not speculate wrongly.

Just a few days after leading the army to the street pavilion, Zhang He looked at the huge siege equipment assembled in front of him in the camp, and a satisfied smile appeared on his face.

The siege equipment in front of Zhang He was called a "catapult" in the world.

As the name suggests, this is a machine capable of catapulting boulders.

It's just that in Cao Wei, catapults have another loud name - thunderbolts.

Zhang He looked at an old man standing under the tall thunderbolt with an inquiring gaze, and he asked:

"Ma Shilang, is the improved Thunderbolt really usable?"

In the face of Zhang He's inquiry, the old man known as Ma Shilang replied with a confident smile on his face:

"Left, General Zuo rest assured, Jun never speaks falsely."

After getting Ma Jun's answer, the smile on Zhang He's face grew.

Zhang He has extraordinary trust in the old man named Ma Jun in front of him.

Ma Jun, the word Deheng, a person who helps the wind.

Although Ma Jun was born poor, he has a deep accomplishment in machinery.

Over the years, Ma Jun invented and improved many machinery in the Central Plains and Guanzhong area, which played a considerable role in promoting the development of the productive forces of the Wei State.

Because of Ma Jun's achievements, the people of the time praised Ma Jun as "the world's famous skill".

The most important thing is that Ma Jun's talent in machinery is not limited to civilian use.

In terms of transforming military machinery, Ma Jun's attainments are also among the best in the world.

Other Wei generals may not know much about this, but Zhang He, who has led the army to sit in Guanzhong for many years, knows this.

Of course, the government and the opposition of the Wei State know that Ma Jun's talent is not only Zhang He.

Otherwise, Ma Jun, who was born poor, would not be able to get the position of squire.

It's just that because Ma Jun came from a poor background, and his talent is mainly reflected in the "strange and obscene skills", this makes many Wei ministers have a lot of resistance to the reuse of Ma Jun.

But Zhang He, who has always had a practical personality, has a different view of Ma Jun.

Because of this, Ma Jun originally served as a squire in Luoyang, but as soon as Zhang He arrived in Luoyang, he immediately asked Cao Rong for Ma Jun to be a member of the army.

Although Cao Rong was puzzled by Zhang He's move, he needed Zhang He to break through the street pavilion for him at the moment, so naturally he would not refuse Zhang He's request that was too small to be smaller.

Zhang He believed that with Ma Jun's extraordinary ability to transform military equipment, his assistance would give the Wei army a considerable advantage in the Jieting battlefield.

Now is the time to prove Zhang He's idea.

Zhang He said to the full favor on the side: "Our army, you can attack!" ”

After receiving the offensive signal released by Zhang He, the main general, as a deputy general, he was fully favored by wearing armor, and immediately ordered the drummers in the army to beat the war drums.

When the high military drums sounded, tens of thousands of Wei troops in the Wei army camp immediately took action.

And because the sound of the Wei army drum was too loud, Liu Feng soon heard the sound of the military drum coming from the Wei army camp.

Listen to the drum and attack!

As a general, Liu Feng stood up almost reflexively.

Without the slightest hesitation, Liu Feng also issued an order to the whole army to meet the battle.

During this period of time, Liu Feng did not relax his vigilance against the Wei army at all, and Liu Feng's prudence kept the Han army in a state of combat readiness at all times.

Therefore, when Liu Feng's order spread throughout the army, tens of thousands of Han troops in the Han army camp quickly returned to their respective posts under the command of their respective generals, holding weapons in their hands and waiting for the Wei army's attack.

Liu Feng also personally took Ding Feng, Deng Ai, and Jiang Wei to the lookout behind the camp gate and watched every move of the Wei army.

When Liu Feng came to the lookout, he found that the gate of the Wei army's camp, which had been closed for several days, had already been completely opened.

From the wide camp gate, groups of energetic Wei troops were walking out one after another.

A few quarters of an hour later, the Wei army, which was the first to walk out of the camp gate, turned into a regular phalanx under Liu Feng's gaze, and walked towards the camp at his feet step by step.

The footsteps of tens of thousands of Wei troops, from far and near, were like muffled thunder in the sky, constantly knocking on the hearts of Liu Feng and the Han army.

Preemptively, this is a method often used by veterans.

If the Han army is not the elite, then this tens of thousands of thunderous sounds of stepping on the ground alone will cause panic in the heart of the Han army.

However, the military spirit of the Han army was not shaken by Zhang He's preemptive move.

The Han army that could participate in the Northern Expedition was naturally elite.

Moreover, with the great victory of Liangzhou in front, the morale of the Han army will only be higher than that of the Wei army.

In this case, Zhang He's preemptive move could not have a big effect.

On the contrary, it stimulated the fighting spirit in the hearts of the Han army.

The Han troops guarding the camp looked at the approaching Wei army, and their eyes became more and more determined.

No matter how many Wei troops there are, they are the one who has the advantage in today's battlefield with the barracks as a barrier.

But just when Liu Feng thought that the Wei army would continue to advance into the range of the Han army's archers, the Wei army's actions were beyond Liu Feng's expectations.

When tens of thousands of Wei troops were two hundred steps away from the Han army camp, they no longer continued to advance.

This is exactly outside the farthest range of arrows in the world.

And not long after tens of thousands of Wei troops stood still, Liu Feng, who had climbed high enough to see into the distance, saw that behind the infantry phalanx of tens of thousands of Wei troops, more than a dozen huge siege machines appeared.

Liu Feng recognized at a glance that the dozen or so huge siege equipment were catapults.

Under the push of the Wei army, the catapult gradually came to the rear of the Wei army's infantry army.

Liu Feng realized that Zhang He should want to use catapults to attack the Han army camp.

But even though he realized this, Liu Feng didn't have much worry in his heart.

During the Battle of Guandu that year, Cao Cao used an upgraded version of the catapult to destroy the buildings of the Yuan army's camp.

Because he knew that the Wei army had this kind of big killing weapon, Liu Feng took precautions early.

At the moment when he saw the Wei army push out the catapult, Liu Feng immediately ordered the Han army to hang wet cowhide on the camp wall.

Although the thunderbolt improved by Liu Ye is more powerful than ordinary catapults, it still has many drawbacks.

The biggest disadvantage of the Thunderbolt is that it can only be single-shot.

A single shot means that the catapult is not very efficient to fire, and it is time-consuming and labor-intensive to fire once.

This drawback fundamentally limits the power of the Thunderbolt, and there is no too high upper limit.

Otherwise, Cao Cao also attacked the black nest back then.

Just drive the road with a thunderbolt and crush Yuan Jun.

And this drawback of the thunderbolt car was also noticed by Yuan Shao back then, so he came up with a way to restrain the thunderbolt.

Yuan Shao's method was to hang wet cowhide on the camp wall.

Wet cowhide has a strong toughness, and in the case of a single shot of the Thunderbolt, the toughness of the Wet Cowhide is enough to protect the camp wall from the boulders emitted by the Thunderbolt.

After ordering the Han army to hang wet cowhide on the camp wall, Liu Feng looked at the dozen or so catapults again.

Liu Feng was a little puzzled, obviously Yuan Shao had already figured out a way to crack the thunderbolt car back then, why did Zhang He have to repeat his old tricks today?

But soon, Liu Feng had more and more doubts in his heart.

I saw more than a dozen catapults stop hundreds of paces away from the Han army's camp, and then many Wei troops were loading boulders into the wooden wheels of the catapults.

After seeing this scene, not only Liu Feng was puzzled, but even Ding Feng and the others looked at each other.

According to common sense, the range of the catapult was at most 200 paces away.

But at present, the catapult of the Wei army is at least 300 steps away from the Han army camp.

At such a distance, can the stones fired by the catapult hit the Han army camp?

In addition, most of the catapults in the world are shaped like a big scale, but today, more than a dozen catapults pushed out by the Wei army are hung with wooden wheels, which seem nondescript, why is this?

Just when Liu Feng and the others were puzzled, the catapult loaded with the boulder began to launch in the direction of the Han army camp.

As a thunderclap resounded through the sky, more than a dozen boulders slammed into the Han army's camp wall under the incredulous eyes of the Han army.

The distance of more than 300 steps did not prevent the boulder launched by the Wei army's catapult from falling on the camp wall of the Han army's camp.

After easily crossing the distance of three hundred steps, the boulders smashed directly on the wet cowhide in front of the wall of the Han army's camp with an unbeatable force.

Because the boulder is too ferocious, although the wet cowhide with excellent toughness has not been directly broken by the boulder, the surface of the wet cowhide has inevitably left shallow dents everywhere.

The Wei army's catapult suddenly had a range of 300 paces, which had already surprised Liu Feng and several Han generals, but what surprised Liu Feng and them was still behind.

I saw that after firing the first round of boulders, almost a moment later, more than a dozen Wei army's catapults launched a second round of boulders.

More than a dozen boulders, with unparalleled momentum, slammed into the wet cowhide in front of the Han military camp wall for the second time.

And because of two consecutive blows in a short period of time, the depressions on the wet cowhide became deeper and deeper, and there were more and more of them.

Just when Liu Feng and the others were worried about this scene, the third round of the Wei army's stone-throwing offensive also roared.

A deafening crash sound resounded in the sky above the Han army camp, making the faces of the Han soldiers slowly turn pale.

If you continue to be hit like this, how long can the wet cowhide last?

Compared with the worries in the hearts of ordinary soldiers, Liu Feng and several Han generals on the lookout tower thought more.

Wet cowhide can temporarily block the boulder of the Wei army's catapult, but what about the camp wall without wet cowhide to protect it?

When this dangerous idea emerged in the hearts of Liu Feng and the others, the sharp-eyed Deng Ai was the first to exclaim:

"The enemy catapult has turned!"

Deng Ai's exclamation was like pulling the Han army into a hell from which it will never recover.

The end of the month is really busy, resulting in a bit of a chapter in between.

When there is a lot of time, I will try to update.

Thank you for your continued support.
