"Blacksmith, take advantage of the fact that the logistics materials have not arrived, during this time, make every effort to make new tools, if the materials are not enough, you can ask the merchants for some broken weapons to melt the tools."

As the enemy's general had a new move, and Yang Qiao also had a new move here, under Yang Qiao's prompt, Changsun Chong also made a new battle plan and made new changes.

"Brother-in-law, remember, this battle plan is not immutable, as long as there is no war, it cannot be said that there will be new changes, even if there is a war, the commander must make some minor changes with the development of the war, naturally, this change must be based on the premise that the order can be fully issued and the soldiers can fully understand, if the soldiers cannot understand, then it is better not to change."

"Okay, Da Lang, I understand, even if you have a book on the art of war, you don't necessarily have to rely on this book of the art of war, you have to adapt to the situation, that's what it looks like, right?"

While waiting for the arrival of logistics materials, Changsun Chong followed Yang Qiao to chat after discussing tactics with the staff officers, and Yang Qiao analyzed some preset battle scenes with Changsun Chong based on some battles he watched on movies and television in his previous life, and even the battle strategies in China, as well as the wins and losses of some famous battles, so that Changsun Chong could add some knowledge.

You must know that these insights are not simply reading books and reading the art of war, and you must also have your own analysis and digestion, you are a nerd, although you can read a lot of things, you may not be able to understand it, even if you recite it backwards, you may not be able to understand it.

Those who may understand are drawing inferences.

Therefore, in just a few days, the amount of combat knowledge of Changsun Chong is already explosive, but fortunately, he can be pressed by the eldest sister after he goes back, otherwise, Yang Qiao is really worried about what will happen to him.

…………

It's redundant, idiot, I can't say, but, indeed, it's blocking the footsteps of the army, not to mention the cavalry, even the infantry, and it's difficult to move forward.

What did this enemy do?

What did he do, the general of the defense, did not set a trap, but organized manpower, dug a lot of trenches in front of the city, and inserted sharp wooden sticks in them, that is, the trap set by Yang Qiao in front of him when he was defending against the night attack, however, he did it clearly, and there was no cover on it, and he also knew that such a big action naturally could not hide the spies of the Tang army, so it was necessary to come clearly, at least, you can't attack at night at night, so that they can sleep peacefully.

The other three city gates, because of the terrain, the other three city gates, or two city gates, because, the city gate behind it, is considered to be their own rear, this, on the contrary, does not need to be defended, only the front gate is the most troublesome.

In this way, the morale of the defenders of this city has risen slightly, but when his trench was dug, he found that this not only blocked the footsteps of the Tang army, but also blocked the possibility of his team going out of the city to fight, and this city could only be used for defense.

"Da Lang, you say, this time, can we still fight quickly?"

With Yang Qiao in front of him, this eldest grandson Chong seemed to have something to rely on, and he actually had to ask Yang Qiao about everything.

"This, you make your own decision, if there is no accident, I won't speak, stinky boy, you follow your brother-in-law, remember, listen to your brother-in-law, otherwise, I will close your confinement well, you be careful, I will draw a circle to close your confinement."

Yang Qiao threatened the stinky boy, however, he also needs to continue to participate in the war, and the little sister, from now on, don't contact the battle, after that, you can only follow yourself to play, and the little sister has also begun to retract, she, participating in the war is just fun, no matter how good the fight is, there is no advantage, the fight is bad, and it is possible to take her life, so she wants to open it.

"A team of engineers, fill the pit in front, and the crossbowmen in the back follow, to prevent the enemy from going out of the city to fight remotely, and wait until about 300 meters away from the city, and then proceed according to the predetermined plan."

There was no need to cover up this sortie, so this team set off in the morning, and Changsun Chong also chose a place to camp early, because of the blockage of the trenches, so this camp was necessary.

"Alas, mistakes, mistakes!"

"But, general, isn't this the best, in this way, it can consume the physical strength of the Tang army, and even time, otherwise, how can we fight, 50,000 people, don't say that this person is few, even the ability of our soldiers is much weaker than the defenders of Liaodong City, they have so many teams are defeated, it is said that the first battle still used 100,000 strongest cavalry, we, what can we do, field battle, steal the camp?"

"You're right, it's mainly their new weapons, new tactics, we don't understand, depressed, depressed, and we can't retreat yet, although, there is a strong city in the rear."

Scratching your head, defeated, defeated here, retreating, may not have a chance to survive, at this time, it is also a time when Goguryeo is complicated internally, until that what Gai Suwen rises.

However, it's a pity that with Yang Qiao, Gai Suwen, who is still in his infancy, shouldn't have a chance, perhaps, he will die of old age with a piece of ambition.

Perhaps, he will lose his life in a certain battle, and even, Yang Qiao doesn't plan to look for that Gai Suwen, it's not worth it.

Although this obstacle is very boring, but, indeed, it also blocked the footsteps of the Tang army, and even, it really caused some impact, the front is good to say, this is close to the city wall 300 meters, there is a danger, because the arrows thrown at the head of the city may float over.

Therefore, when he reached 300 meters, Changsun Chong changed his tactics, that is, originally, it was processed on the surface, but when he arrived here, he began to go down the trenches, and when he got down the trenches, the first thing that needed to be dealt with was those sharp woods, fortunately, he could be reused, at this time, it was not a good time to fill the pits, but the trenches were used to turn in, and then, in the corresponding places, they were modified into roads, but they needed to go up and down, but they did not affect the advance of the cavalry, that is, they affected some speeds, and trebuchets, It can be projectile from a distance of 300 meters, and there is no danger yet.

This, even if the defenders themselves lifted a stone to shoot themselves in the foot, this trench also blocked their attack, and they could only watch the Tang Army erect high shelves one by one, naturally, they would not think that these high shelves were useless things, they must be some new weapons.

In this way, this trebuchet can be fully prepared and will not be attacked, and the sappers in the trenches, because of the blocking of the trenches, have all reached the bottom of the enemy's city walls, and this projectile or direct shot cannot shoot them, so they are slowly cleaning the wooden thorns in the trench.

In this way, the Tang army is not in a hurry, and comes slowly, so that it can also consume the morale of the other party.

In this way, it took about ten days for the sappers to reach the city, and the guards on the city were all hairy.

And what they don't know is that those merchants' private soldiers have slowly surrounded the city, naturally, in order to catch slaves, at this time, they have also formed a tactic, that is, the siege of the city is not besieged, they besiege the city, and they do not let the other party know, and, even if they know, people will not care, you are such a little person, what can you do, yes, what can you do, naturally you can catch slaves, once the slave runs, it is not caring about anything, naturally it is easy to catch ruthlessly.

This is also one of Yang Qiao's tactics, that is, to start a battle, it is strictly confidential, and the defenders of the next city can only know a little bit of news, but they can't summarize anything.

"This kid, this time, why aren't you in a hurry!"

Li Jing was a little anxious in the back, that is, he was not in a hurry.

However, Li Jing was not idle, behind Yang Qiao's army, their team also set up temporary camps, which brought more pressure to the defenders in the city.

"Da Lang, you say, do you want to let the general's army follow the attack this time?"

Seeing Li Jing's army, the eldest grandson suddenly came up with a new idea.

"This, you have your own idea, there are benefits together, and there are benefits alone."

Yang Qiao didn't even give any advice, but he was embarrassed by the eldest grandson, and then, he discussed it with those staff officers.

"Okay, that's it, Da Lang, you forced me!"
