Even so, Cao Cao still believed that these gunners of the cavalry army were really capable.

Cao Cao originally thought that under this windy and snowy sky, the artillery grenades and other artillery would turn into scrap metal. Unexpectedly, the artillery above Tongguan still had two more doors to open fire.

Is this a temporary shed to hide the wind and snow?

Or is it possible to solve the problem of gunpowder moisture?

However, even if there are moisture-proof methods, as long as it is used in the wind and snow, there will be not many fuses and gunpowder that are not affected by moisture?

Sure enough, it didn't take long before the artillery stopped completely.

It's like the war drum behind Cao Cao.

The skin was stained with wind and snow, and the sound could not be made.

Even without the war drums as an inspiration, the Cao army soldiers on the front line seemed to have stronger fighting spirit. They cheered and rushed forward, as if for these Cao army's auxiliary soldiers, as long as there was no threat of artillery, it was something worth celebrating.

Cao Cao looked at the big rock in his heart, as if it had loosened a little.

But after a moment, another bitter smile appeared on the corner of Cao Cao's mouth.

Compared with the soldiers of the cavalry, although the elite of the Cao army was also called elite, they were more accustomed to facing the original combat mode and facing the old-fashioned swords, guns, and rolling stones, rather than using new weapons.

Yes, the old pattern.

Most people like the old pattern and always have an inexplicable sense of fear about new things.

Because that's unknown...

The same is true for Cao Cao. He is also afraid when facing his unknown.

Cao Cao thought he could change the ills of the Han Dynasty, and thought that the root of the ills of the Han Dynasty was just like those Qingliu said, it was in the eunuchs, and Cao Cao also truly saw the misconduct of eunuchs and eunuchs' relationships, so he created a five-color stick. After he took the five-color stick, Cao Cao realized that killing a few eunuchs was useless.

So, killing all the eunuchs is equivalent to curing the great man?

Perhaps with this idea, when Yuan Shao entered the palace, Cao Cao also took action. Then he discovered again that the eunuchs were not as important as they imagined. After killing such tigers and leopards, the Han Dynasty was still corrupt and the court was destroyed.

So, where exactly is the problem?

Then Cao Cao felt that it must be the powerful minister Dong Zhuo who was in trouble with the court...

After all, Shandong Qingliu said so at that time.

And now, he has become a "powerful minister" and is attacking another "powerful minister".

Back then, Cao Cao wanted to pursue Dong Zhuo, at least one Bao Xin followed him, and now...

Bao Xin is dead.

Cao Cao is still lonely.

Therefore, the root cause of the disease of the Han Dynasty is really the eunuch? Or the powerful minister?

Or somewhere else?

Cao Cao had the answer in his mind.

But he was avoiding that answer.

The big man is like a big tree that has been decayed by fungi. It seems that there are still some places that are intact. You only need to remove the decayed places after you really move the knife. However, after you really move the knife, you will find that one place is removed and another place. If you use the knife everywhere, will this big tree still exist?

Cao Cao waved his sword, looking like he opened and closed, but in fact he was careful.

"I'm so envious..."

Cao Cao whispered, then looked up at Tongguan.

After Cao's army approached within 500 steps, the crossbows on the top of Tongguan City shot angrily, but it stopped after not long.

The bowstrings of the crossbows will also get damp, so this time you can reach the city of Tongguan and the side of the trench, there are more shield cars on the edge of the trench than before.

The trenches in Tongguan were originally more than two meters deep, but in the previous battles, many places had been filled or dug. Many places of the trenches collapsed, and the spikes inside the trenches were also flattened.

As the shield car stood up in front, the car and other vehicles following behind quickly followed.

The soldiers of Cao's army rushed up like ants who saw honey, layer by layer. Some were digging and filling the pits, some were pushing wooden boards to build temporary bridge decks, some climbed up the Arrow Tower and shot against the soldiers in the lower city of Tongguan, and some tried to hook up with a new attack channel with ladder trucks...

The effectiveness of arrows in the wind and snow was also reduced. As the bowstring was damp, the power of arrows gradually decreased, so both sides quickly stopped this method that had little effect.

Everything was exactly as Guo Jia expected. The long-range weapon of the Cavalry was greatly suppressed, but Guo Jia was still a little nervous and clenched his fists in his sleeves.

Soon, something Guo Jia was worried about happened.

The grenade was thrown down.

Guo Jia stared at it tightly, then counted the number. After a while, he let out a long sigh and "It's done."

Cao Cao smiled and nodded.

Grenades also received the impact of wind and snow.

The power of the explosion seemed to have dropped a lot, not to mention that some grenades were extinguished by wind and snow even if they ignited the fuse.

"In this way, only the last trick left..." Guo Jia said slowly, but his tone had become much easier.

After suppressing the gunpowder, all combat modes entered the range that Cao's army was accustomed to.

Just as Guo Jia said, there is only one way to stop these siege equipment from destroying the city wall.

Several shield chariots and chariots crossed the trenches and entered the Tongguan city wall. When Cao's soldiers were preparing to dig holes to destroy them, they poured turbulent oil from the city wall.

The torch was thrown down.

Even in the wind and snow, the power of tinder oil is still violent. The flames rising from the sky roar in the wind and snow, and rolling black smoke filled the city walls.

Cao's army had to suspend the offensive.

The shield and chariots that arrived first under the Tongguan city wall were destroyed, but a new batch of siege equipment gathered in the rear.

The fire was raging under the base of the city wall and could not attack for a while, so Cao's army temporarily stopped.

A batch of steamed cakes and hot soup that had just been released were carried by the leader and sent to the front line.

Many Cao army soldiers caught and ate it without caring about the blood, cement and water stained on their hands. They knew that although the fire caused by this tincture oil was fierce, it could not last long. If they didn't eat something at this time, then if they died in battle, they would be a starving ghost.

However, even though the attack on Tongguan was still alive, the soldiers of the Cao army seemed to have seen hope. At least now the Cavalry Army was forced to be on the same level as them under the wind and snow. The dangers and threats that the soldiers of the Cao army had to face were all familiar to them, and were no longer those terrifying derivatives of gunpowder, which made the morale of the soldiers of the Cao army unknowingly improve.

Before, the Cao army was forced to follow the rhythm of the cavalry and was suppressed by the cavalry's new weapons. Now they seem to be able to play with the cavalry in this mud again...

Cao Cao was about to turn in, he was about to go to Hedong.
