Cao Cao ordered, and the arrow shaft was fired.

However, at this time, the gate of the Tiger Prison was not blocked with a boulder, but it was completely opened, and all the crossbow arrows shot in it failed.

Such a scene made Cao Cao and them stunned.

"Stop!"

Cao Cao waved his hand.

Those soldiers all stopped and looked at the gate of the Tiger Prison that had been opened, and they thought that they had seen something wrong, but the gate of the Tiger Prison was really open, and the soldiers inside didn't seem to want to guard it.

"Lord, there must be something wrong with Yang Zhao doing this."

Chen Qun frowned and said, "There is no one on the city tower to defend it, and at this time, the gate of the pass is opened, what does Yang Zhao want to do?" ”

Cheng Yu said: "Yang Zhao's move seems to be trying to lure us in. ”

They looked at the open gate and stopped everything, wanting to go in, but they were afraid that there would be an ambush behind them, if they didn't go in, if there was no ambush, it was Yang Zhao who did it on purpose, wouldn't it be a blood loss.

Yang Zhao's action made Cao Cao unable to rectify.

"Lord, what should I do?"

Le Jin came over and asked.

Cao Cao was silent for a long time, shook his head and said: "You can't go in, Yang Zhao is behind the pass, there must be some ambush and trap arranged, stop the attack, retreat one after another, I want to see how long the gate of the Tiger Prison can be opened." ”

They didn't dare to attack rashly again, worried that Yang Zhao would have some tricks, so they would retreat temporarily, and then let people stare at the gate of the Tiger Prison.

Cao Cao didn't believe that Yang Zhao would give up the tiger prison and leave it alone.

Chen Qun and Cheng Yu were also hesitant and didn't dare to do anything.

Kannai.

Yang Zhao looked out and said with a smile: "I knew that with Cao Cao's suspicious character, he didn't dare to come in." ”

Feng Ming said: "Even if Cao Cao is not suspicious, he doesn't dare to come in, the lord opens the gate for no reason, no matter who is tackling the problem outside, seeing such an impossible situation, he doesn't dare to rashly attack in." ”

What's more, what they are playing is not an empty city plan.

If you dare to hit in, you will really die, there are really traps behind the closed door, artillery machine guns, etc. have long been prepared.

Yang Zhao laughed and said unhurriedly: "Continue to open the gate, arrange a group of people to take turns to guard, and if there is a situation, immediately sound the gongs and drums, and there is no need to be stationed obviously, I want to see how long Cao Cao can hold out." ”

Those explosives packs alone can't blow up the walls of the tiger prison.

Unless they hid the explosives inside the city wall and blasted them in a directional manner like Taiping Road, but Cao Cao didn't have this technology, let alone the principle of blasting, so he couldn't do it at all.

Yang Zhao was very calm now and continued to open the gate of the pass.

The time soon came to night, and Cao Cao went out of the camp again to look, only to see that the gate of the Tiger Prison had not yet been closed, and had been open to them, as if to lure them in, and the doorway was full of temptation.

"Zhicai, what's wrong with them?"

Cao Cao asked.

Chen Qun said: "I have already asked people to send a letter to Zhicai and them, and they can almost attack the southern part of Luoyang." ”

Cao Cao said worriedly: "Attacking the southern part of Luoyang, can we still succeed?" ”

Chen Qun and Cheng Yu were silent at the same time.

Before the expedition, they were full of confidence, but outside the Tiger Prison Pass, Yang Zhao made them suspicious of life, with Yang Zhao's ability, they would not be unguessed, they still wanted to attack the south of Luoyang, if there was any special operation, Xi Zhong and Chen Gong they, wouldn't they have to stop again.

Cao Cao said: "The matter has come to this, it is impossible not to fight, it is too late for us to lead the troops to retreat, Yang Zhao has cleaned up Sun Quan and Liu Bei, and he will definitely fight us in Yuzhou and Yanzhou." ”

This is also true.

Once you've decided to fight, you can't stop.

"Keep waiting!"

Cao Cao said again.

Before I knew it, it was the next morning.

The gate was still wide open, there was no movement inside, and there were no soldiers on the castle tower.

At this time, Yang Zhao and Feng Ming were in a place where Cao Cao and the others could not see, observing Cao Cao's movements.

"Lord, why don't we just retreat?"

Feng Ming looked to the south and said: "This place is connected to Songshan Mountain in the south, with staggered mountains and the Yellow River in the north, as long as we hide in one of the mountains to ensure that the tiger prison is within the range of artillery fire, and then in the upper reaches of the Yellow River, prepare enough ships." When Cao Cao entered the Tiger Pass, we bombarded it with artillery fire from the mountain, and the ships went down the Yellow River, cutting off Cao Cao's retreat, not only to repel Cao's army, but also to capture Cao Cao. ”

Yang Zhao looked at the north and south for a while, thought about it for a long time, and clapped his hands: "Then do it!" ”

"Retreat all!"

He divided the soldiers into two parts.

Some climbed the mountain, and some had enough boats upstream, with a large number of bows and arrows on board.

Then give up the Tiger Prison Pass.

The door of the Tiger Prison was kept open, and Cao Cao would definitely not be able to help but send someone in to investigate.

As long as he really sent someone in, Feng Ming's plan would almost come true.

While Yang Zhao retreated up the mountain, he let people erase all kinds of traces on the road, and soon there were no guards inside the Tiger Prison.

Only the shadow hides on the nearby slope, watching everything below.

This majestic pass, quiet and quiet, there is nothing.

Outside the customs.

Cao Cao paced back and forth.

I couldn't see Yang Zhao coming up again, and I couldn't see the soldiers guarding the pass appearing, as if there was no one to defend it, and it seemed to be full of all kinds of traps.

"Send someone in and have a look."

More than a dozen scouts who were not afraid of death were sent out by Cao Cao and went deep into the Tiger Prison Pass.

After about an hour, they investigated clearly, hurriedly walked out, shook their heads, and said, "There is no one defending in the pass. ”

"Check the soil in the gate, dig a foot down to see if there is anything unusual, and arrange for people to go to the nearby mountains to see if there is any problem."

Cao Cao didn't believe that there would be no one to defend him.

This time, not only the scouts, but also more than a hundred soldiers entered the pass, searched the tiger prison tightly, rummaged through, tried to find the ambush inside, but found nothing.

The nearby mountains were staggered, and the Cao army scouts were not familiar with the terrain, and even if they entered the mountains, they still failed to find anything.

In the end, nothing was found.

"Can't find it?"

Cao Cao frowned and asked, "What do you think?" ”

Cheng Yu guessed: "Could it be that something happened in Guanzhong, Yang Zhao had to lead his troops back to rescue, so as to give up the Tiger Prison Pass and only prepare to defend Luoyang?" ”

Chen Qun said: "This is unlikely, even if Guanzhong is in danger, it is impossible for him to give up the Tiger Prison and leave it alone, not to mention that Yang Zhao's firearms are all useless, so he will leave like this, do you think it is possible?" ”

It's really not very likely.

Looking at the door in front of him, Cao Cao's heart was like a cat scratching, and he wanted to go in and take a look, but he didn't dare much.

"If I continue to arrange people to go in, I don't believe it, and I can't find the problem in the Tiger Prison."

Cao Cao considered it in the end, and sent someone to investigate.
