Soon, it was night again.

The shadow went back to report, but Cao Cao still did not advance or retreat, and hesitated outside the Tiger Prison Pass.

"Tongfang's plan is a bit damaged."

Yang Zhao couldn't help but laugh and said: "The more we are like this, the more entangled Cao Cao will be, the more restless he will be, even if he doesn't come in, the entanglement can make him uncomfortable, and it will drag on for a long time, and it will be unfavorable to them, not us." ”

Cao Cao's plan was to use the attack on the Tiger Prison Pass to attract Yang Zhao's attention, so that they could attack the Yuyuan Pass and the Dagu Pass.

At this time, Yang Zhao was mainly anti-guest, and Cao Cao, as the party that took the initiative, fell into passivity, not to mention how uncomfortable it was.

Feng Ming said with a smile: "I'm just using a little trick, in the Tiger Prison Pass, the time and place are favorable, all on our side, plus there is an absolute advantage in strength, and there is firearm assistance, so it has such an effect." ”

Cao Cao was mainly afraid of Yang Zhao's strength, as well as the new firearms that Lu Su had mentioned and that they had never seen before.

Fearful of these, Cao Cao did not dare to mess around, if other people dared to play like this, Cao Cao might send a team of pioneers who were not afraid of death to kill to open the way, and then use the army to advance and forcibly occupy the Tiger Pass.

"You're very analytical."

Yang Zhao nodded slightly.

They are not in a hurry, continue to wait, and at the same time let people check the situation in Guanzhong and Lujiang to ensure that they have no problems.

——

The next morning.

Cao Cao went out of the camp again and looked at the Tiger Prison Pass.

He really wanted to ask Xi Zhong's opinion, but the distance was so far that it might delay the time for people to go to Yuyuan Pass and come back, causing the situation to change.

Now when he goes in, he is afraid, if he doesn't go in, he will be dragged here again, if he retreats, everything he has done will be in vain, and their plan will have to change since they met Yang Zhao, which is completely different from what they thought at the beginning.

Who would have thought that Yang Zhao would not play cards according to the convention.

"My lord, you give me 2,000 men."

Lu Bu couldn't help but say: "I'll help you go in and see how the situation is, if there is no danger, the army will come in again, control the Tiger Prison Pass, and go to Luoyang." ”

Cao Cao hesitated, and confirmed: "Arrange two thousand people to pass in first, control everything inside, how can I let Feng Xian take risks?" Wait outside together. ”

Two thousand soldiers, soon entered the Tiger Prison.

They were unharmed and nothing happened.

Cao Cao's heart was a little stable, and he arranged for another 5,000 people to go in, and there was no problem, Yang Zhao seemed to have really retreated, and he no longer defended the Tiger Pass.

So, Cao Cao further probed.

Continue to arrange people to go in, as half of the army entered the Tiger Prison Pass, there was still no other movement inside, and the safety was still the same, he and Cheng Yu glanced at each other and felt a little incredible.

"Yang Zhao really retreated?"

Chen Qun said in disbelief.

Cheng Yu said: "Lord, how are we? ”

Cao Cao decided to let go and said in a loud voice: "All enter the customs." ”

Le Jin said: "Lord, for safety, let me go in and take a look!" ”

The current situation is getting more and more weird.

How can Cao Cao go on an adventure.

Cao Cao agreed.

Le Jin led the troops into the Tiger Prison Pass first, he personally led the troops, and searched again in it, and could not find any suspicious places, ambush traps and the like, and could not see it, so he expanded the search scope and searched for several miles in a radius.

Except for the mountains, they are unfamiliar with the terrain and cannot go deep, everything else is normal.

After the news of the safety in the Tiger Prison was sent to Cao Cao, they hesitated again.

However, all aspects have proved that the Tiger Prison is safe and there are no problems.

Chen Qun and Cheng Yu also hesitated, if Xun Yu or Xi Zhong were there, they would persuade Cao Cao not to go in, but Chen Qun and the others couldn't see the situation in front of them clearly.

"Let's go inside!"

Cao Cao decided to let it go.

They entered the Tiger Prison and were still unharmed.

It's just that their every move is under the surveillance of the shadows, and seeing that Cao Cao also entered the pass, they hurriedly sent someone to tell Yang Zhao.

"It's coming!"

When Yang Zhao heard this, he waved his hand excitedly.

Artillery and mortars, condescendingly, aimed at the pass below.

The shells are fired from top to bottom, and the distance that can be shot out is farther, and the range of the mountains on this side can just cover all of the Tiger Prison Pass, and when the artillery is ready, Yang Zhao said again: "Fire coverage, open the cannon!" ”

Rumble......

Cannon fire appeared above the mountains.

At the same time as the cannon was fired, except for the soldiers who controlled the artillery, the other soldiers followed Yang Zhao down the mountain, and when the shells were almost finished, Cao Cao and the others wanted to exit the Tiger Prison Pass, they went out and fought in short combat.

Cao Cao came in, successfully controlled the Tiger Prison Pass, and there was a feeling of disbelief, and when he was about to discuss when to attack Luoyang, suddenly a burst of artillery rang out, coming from the mountain range next to him.

Hearing this voice, they instantly understood that it was going to be bad.

The most feared thing still appeared.

"Let's ...... away"

Cao Cao shouted eagerly.

But before they could run out, the artillery shells fell among the soldiers and exploded, knocking down a large number of Cao soldiers.

There really is an ambush!

They knew that Yang Zhao would not leave easily, but they were unwilling, so they had to come in and give it a try, but after being bombarded for a round, the Cao soldiers were in a mess, and the rest ran around, not knowing what to do.

"Lord, this way!"

Le Jin protected Cao Cao and shouted: "Quickly withdraw from the Tiger Prison!" ”

Lu Bu shouted: "Don't mess up, integrate everything, leave the Tiger Prison Pass, the lord will go first!" ”

Those Cao soldiers were in confusion and all crowded towards the gate.

They also blocked Cao Cao's way, and when they heard the sound of artillery on the mountain again, Yang Zhao's artillery bombarded again, and Lu Bu rushed directly over, killed the soldiers who blocked the gate, and forcibly rushed out with Cao Cao.

Those Cao soldiers who had not yet rushed out continued to accept the baptism of artillery fire, and the sound of cannon fire echoed in the pass.

Cao Cao had never tried, he was so embarrassed as today, and it was all up to Lu Bu to save him desperately to get out of the Tiger Prison, at this time, he couldn't care about anything else, and shouted: "All retreat." ”

Seeing that the shelling was almost over, Cao Jun also withdrew from the strike range.

Yang Zhao led his soldiers down the mountain and into the chaotic rear army of Cao's army.

Chase and kill.

——

Upper reaches of the Yellow River.

Not far from the Tiger Prison Pass, in a river embankment, Xu Chu and Dian Wei led Long Wei, as well as 5,000 soldiers, who have been squatting here.

The sound of the cannon was their agreed call.

At this time, I finally heard the sound of artillery echoing in the direction of the Tiger Prison Pass, and Xu Chu said loudly: "Do it!" ”

The nearest wind is blowing right in the west.

Their ships sailed smoothly, and then they were blown by the wind, and they sailed downstream at the fastest speed, and in the blink of an eye they came to the edge of the Tiger Prison Pass, which at this time was being baptized by artillery fire and was in chaos.

As soon as the ship crossed the Tiger Prison Pass, Dian Wei shouted: "Put away the sails, dock, and kill it!" ”
