The other agreed, and they were all curious about the defenses of their walls.

So, the two went down the city wall, went out of the city, went out of the second city gate, walked south, and found the place where the Han army was bombarded by artillery.

At first glance, it was terrible, and a three-foot-deep pit was dug down, and I saw that the iron plates inside were blasted out of the pit. Fortunately, the wall was eight feet thick, and if it was only five or six feet, it would have collapsed by cannonballs, even if it hadn't been blasted out of the hole.

"This Han army's artillery is really powerful!" A guard touched the deep pit in the wall and exclaimed.

"Isn't it? You know, the iron plate in the middle is two inches thick, and this has made a pit, if you continue to let the Han army fight, this iron plate may not be able to parry! The other guard also said in amazement.

"That's right, fortunately, we launched the rocket in time and drove the Han army away. Otherwise, it's really a bit hanging! The guard said with some trepidation.

Another guard said, "Brother, but this time we have gained a lot!" ”

The guard general said: "Yes, not only has the defensive ability of the new city wall been tested, but also the power of the rocket army has been tested, this battle can be described as killing two birds with one stone!" ”

"That's right, let's go back and report to our superiors with a smile, report to General Lunta, and let him know, so that the imperial court will increase the construction of this kind of city wall." The other guard said with great excitement.

"Let's go, we'll go back now." The defender was also very happy to say.

"But what about this pit?" The other guard asked.

"It's easy to do, just find someone to build with stones." The guard said.

The other guard nodded, smiled, and said, "Okay, I'll go back and go our separate ways." ”

The two of them said and walked away together. There was still that big pit in the city wall, and when the wind blew, it swirled in the pit and brought out some dust.

After about a cup of tea, another man appeared in front of the pit in the city wall. The man, dressed in a dry grass-colored garment, was drenched, and was reaching for the pit in the wall. I touched the pig iron. There was a look of surprise on his face. If you look closely, the layer inside is really pig iron.

After observing, the man looked left and right like a thief, and then quietly climbed into the moat and dived under the water, there was no one left, and even sleep became without a trace.

After another cup of tea, a few Tatar soldiers came pushing stones and cement, built a bridge, crossed the moat, and began to repair the crater that had been blasted by the shells of the Han artillery.

Ten feet to the south, in a bush spot, a man crept out of the moat into the bushes on the other side, like a rabbit.

The man ended up standing wet in the big tent of the Han army.

Cao Wen asked, "Do you understand what's going on with the wall of the Tarnu army?" ”

The man said, "General Hui, my subordinates have seen clearly, there is a three-foot-deep pit where the wall of the Tatar army was bombarded by our artillery, and there are pig iron plates in the pit. ”

"Pig iron plates?" Cao Wen asked with a frown.

The man nodded and said, "Yes, General, there is a cast iron plate between the walls of the Tatar army. ”

Cao Wen pondered, nodded and muttered: "No wonder the cannonballs can't penetrate it, it turns out that there is a pig iron plate in the middle of this city wall." The Tatars have also taken great pains to block the artillery. ”

The anxious lieutenant general beside him said, "General, this is extremely unfavorable for our siege!" ”

"Do you still have to say that?" Cao Wen said.

"Yes, General." The lieutenant nodded.

Another lieutenant asked, "General, what should we do next?" ”

Cao Wen first waved his hand to the wet soldier to signal him to go first, and then said, "It seems that this matter is to be reported to the general." ”

The lieutenant general nodded and said, "What the general said is very true, and his subordinates will grind ink for my sister."

Cao Wen didn't object, just squinted and frowned, as if he was thinking about how to break through such a strong city wall.

In a few moments, the lieutenant had the paper and ink ready.

Cao Wen began to write, first to write down the siege of the city, and then to write about the city walls of the Tatar army.

"Okay, send someone to the general of Cuiping County as soon as possible.

"Yes, General." The adjutant took the letter and went out.

At this time, Wu Qing sat in Cuiping County to supervise the war.

Five hours later, Wu Qing received Cao Wen's letter, opened it, and frowned. Gao Tang was by Wu Qing's side and was Wu Qing's lieutenant.

And Chen Cheng led the troops to attack Huangzhou of the Tatar army. Even if the attack cannot be attacked, it must be harassed, so that the Tatar army will always remain in a state of panic.

Seeing Wu Qing's frown, Gao Tang asked, "General, is it not smooth to attack the land of Zhangzhou?" ”

Wu Qing didn't speak, but handed the letter to Gao Tang. Gao Tang took it in his hand and looked at it, and then frowned. After a moment of silence, he said, "How did this Tarnu army come up with such a city wall? ”

Wu Qing said: "Do you still need to ask? It was to prevent our artillery from attacking. ”

"Well, the general is right. It seems that the Tatars have made a bloody investment. Gao Tang nodded and said.

"What do you mean?" Wu Qing asked.

Gao Tang arched his hand and said: "General, what the last general means is that since the walls of this Zhangzhou City have been added with two city walls and iron plates, then the walls of other cities must also be equipped with iron plates." This is also a big project, in terms of the financial resources of the Great Yang Dynasty, this is indeed an out-and-out bloody behavior! ”

After listening to Gao Tang's words, Wu Qing nodded and said, "You're right. This made it very difficult for us to attack the city. ”

Gao Tang said: "Yes, General, our army relies on artillery to attack the city, and if this artillery can't be used, we will have nothing to rely on when attacking the city." You can't set up a ladder, and the tactical losses of such a sea of people must be quite large.

"Crowd tactics? Ladder? Your Majesty will not do this. Wu Qing said.

Gao Tang nodded and said, "That's right, Your Majesty's most important thing is the lives of the soldiers, and Your Majesty will never do this." But what about us? ”

Wu Qing pondered, facing such a situation, there was nothing he could do in his heart.

Gao Tang saw that Wu Qing didn't answer, so he didn't ask anymore, but just looked at Wu Qing from the side. is also waiting for Wu Qing's instructions.

After a while, Wu Qing said: "Gao Tang, we have to show Your Majesty about this matter!" ”

Gao Tang nodded and said, "Then let the last general go back to Pingliang Prefecture to His Majesty!" ”

Wu Qing shook his head and said, "No, you stay, General Ben will go back." ”
