The tunnels that Guo Jia wants to use are the ones that have not yet had time to dig through before.

Previously, due to his own tunnel tactics, he was easily cracked by the enemy, so Liu Yuan ordered to stop, this meaningless way of attacking.

Although some tunnels did not continue to be dug forward, the previously dug ones were not abandoned, but the cave was buried by the soldiers of the Jizhou army.

Now if you want to enable it again, you just need to dig up the floating soil at the entrance of the hole.

In this way, it will take at most, just two to three days, to get the tunnel under the walls of Cao Jun.

At that time, as long as they bury a large dose of explosives and detonate them, they will definitely be able to collapse the city wall on this side, and then the Jizhou army can immediately attack the urn city inside.

Compared to the outer city wall, although the inner urn city has also been repaired, it is definitely not as impregnable as the outer city wall.

For an elite like the Jizhou Army, once Cao Cao and the others lost the protection of the outer city, it was tantamount to being directly exposed to the wilderness.

At that time, Cao Cao and the others will be able to escape with their lives, which is already a blessing to invite the heavens, let alone what is it to defend the city in front of them, it is absolutely impossible!

When Guo Jiajiang's strategy was finished, Liu Yuan nodded with great satisfaction, in fact, this strategy is not too complicated.

As long as there are generals and above in his army, they should be able to think of it.

But their thinking has always been too single, and they have not thought of combining the two ways to attack the city.

This can only be said to be myself and others, and the grasp of the situation and the use of strategies are not yet in place, and these are all areas that need to be improved in the future.

The problem that bothered him before was solved by Guo Jia seemingly easily, and the sadness on Liu Yuan's face dissipated a little.

But if you look closely, you can still see that Liu Yuan is not completely relaxed at this time.

Guo Jia knew at a glance that although he had solved Liu Yuan's urgent need, he had not solved all the problems of his father-in-law.

Now what the lord is worried about, in addition to the fortified city in front of him, the rest are the princes who are being persuaded by Lu Bu's people.

If those princes intervened in the battle between them and Cao Cao and others at the most critical moment, the pressure on Jizhou would have increased exponentially at that time.

Although Jizhou's armor has been crowned with the world, they have not yet made sufficient preparations to compete with the whole world with the power of one state.

If these princes give them another five years, what will they do, even if they are enemies of the whole world?

At that time, the lord will not have to scruple at all, anyone's attitude, and he can level the world with a direct wave of the army!

For a while, Guo Jia also fell into contemplation, and he wanted to come up with a solution to those wait-and-see princes as soon as possible.

Even if you can't let them cast a rat trap, you must make them dare not act rashly!

But such a strategy, where can be thought up in an instant, with Guo Jia's world-class resourcefulness, it is also an incomparable headache for a while.

Just when Guo Jiadu was already thinking about it, and his brain was hurting, suddenly there was a familiar sound of footsteps from outside the tent, and then someone walked in as soon as he lifted the curtain of the door.

Liu Yuan and Guo Jia looked up at the person who came almost at the same time, and the person who came was the other two strategists in Liu Yuan's army who could be compared with Guo Jia.

One is Xi Zhong and Xi Zhicai, and the other is Jia Xu Jia Wenhe!

As soon as they saw the two of them coming together, Liu Yuan and Guo Jia's hearts moved at the same time, looking at the appearance of the two of them, could it be that they also thought of a solution to the problem?

Just when Liu Yuan wanted to open his mouth to ask, Xi Zhong had already come to him, and stretched out his hand to stop Liu Yuan's questioning a little rudely.

Immediately afterwards, he made a request to Liu Yuan, a request that made Liu Yuan confused, and Xi Zhong directly offered to let Liu Yuan send him a bunch of people.

And the scale of this team is not small, but Xi Zhong asked Liu Yuan to send more than eighty percent of the cavalry under his command to his command.

Although Xi Zhong's request made Liu Yuan a little confused, out of trust in Xi Zhong, Liu Yuan still nodded and agreed to Xi Zhong's seemingly reckless request.

Just the moment Liu Yuan nodded, Guo Jia noticed that Jia Xu's eyes had changed.

This old guy usually looks extremely calm, but at this time, his eyes also showed a feverish look.

This made Guo Jia realize at that time that Xi Zhong and Jia Xu must be going to do an extremely crazy thing, something that could change the crisis they were facing at this time.

Sure enough, when he saw Liu Yuan nodding and agreeing, Xi Zhong said his plan, and as he spoke, Liu Yuan and Guo Jia's mouths were slowly opening up.

Neither of them expected that Xi Zhong would be so crazy this time, he would lead a group of men and horses to rush thousands of miles to attack Han Sui, who was fighting with Zang Ba and others at this time.

After listening to Xi Zhong's plan, with Liu Yuan's boldness, he couldn't help but secretly wipe a cold sweat, Xi Zhong's idea was too bold.

He believed that at this time, the reason why Lu Bu was able to connect those undecided princes was precisely because Han Sui helped him drag Zang Ba's footsteps.

As long as Zang Ba's forces can be liberated, with the combined efforts of him and Zang Ba, even if they can't completely defeat Lu Bu's forces, at least they can force the other party to take care of themselves.

Once there was no Lu Bu as the initiator, and they showed almost overwhelming strength, those wall-like princes would definitely not dare to act rashly.

In this way, the dangerous situation they faced will be self-defeating, and in Xi Zhong's plan, he also piggybacks on Emperor Xian and other ministers of the court.

Xi Zhong planned to join forces with Zang Ba to perform a play, that is, to let Han Sui's people rush into Chang'an City before they attacked Han Sui and the others.

Isn't the main purpose of Han Sui's attack on Sizhou this time to be for the Han court, which has become virtually useless at this time?

Since he wants such a chicken rib court, of course they are willing to give it to Jizhou.

Han Sui only thought that he could order the princes with the Son of Heaven, but he didn't expect that even if the Son of Heaven was in his hands, he didn't have the strength and reputation to command the princes.

The Son of Heaven was in his hands, and apart from being able to hinder his strength, it would not be of any substantial help to him at all.

Even so, Han Sui didn't dare to easily touch the Son of Heaven, unless he was ready to be ruined and stinking for eternity like Dong Zhuo.

And when Han Sui took the Son of Heaven in his hands, Han Sui at that time would definitely be extremely proud, and that was when Xi Zhong and others were in trouble.

At that time, the complacent Han Sui army will definitely be defeated.

Of course, they must not knock Han Sui to death this time, after all, the Son of Heaven is not only a constraint for Han Sui, but also a hot potato for Jizhou!
