It was very simple for Chu Hong to get the fragments, and the things were quickly delivered to the house.

After the war, the city walls were cleaned, and these things were put together, and as a trusted advisor, they had the right to study and facilitate the formulation of strategies.

Although Chu Hong felt that this was inappropriate, he didn't want his niece to get involved. But he didn't want Boping City to be breached, so that Liangzhou fell into the hands of outsiders.

At least he believed in his niece's talent and might be able to find a way to defeat Ning Ze.

Chu Wenxiuzai carefully observed several times, placed each piece independently, and drew a picture while thinking.

Some of the repetitive pieces are eliminated one by one, and the places that seem to fit together are also remembered and drawn with a brush.

After a long time, a crossbow arrow that was almost indistinguishable from the real thing appeared, and there was even a sketch similar to a cross-sectional drawing.

Chu Hong has been watching from the sidelines, and saw with his own eyes that his niece had restored the shape of the complete crossbow arrow step by step by carefully observing the fragments, and said in his heart how good it was for her to be a man.

His eyes fell on the drawings, and he asked softly, "This crossbow arrow has a strange shape, which is quite rare!"

Chu Wenxiu said: "I have seen a hundred soldiers' genealogy, which records all the styles of weapons throughout the ages. This kind of crossbow arrow is unheard of, and it should be created by Ning Ze himself. This picture was created by me by restoring fragments, and many places cannot be connected, so I can only fill in by guessing. But the difference will not be much. The crossbow bolt itself is not unusual, but the arrow is more special, it is actually hollow, and the volume is larger......"

"After this arrow was shot, why did the thunder appear? Can you see it?" Chu Hong hurriedly asked.

Chu Wenxiu closed his eyes and thought about it, then opened his eyes and pointed to the arrow part on the drawing: "Second uncle, do you think that in terms of this arrow alone, does it look like a firecracker?"

"Firecrackers?" Chu Hong looked at it suspiciously, it was really a bit similar.

Although there are no thermal weapons in this world, and gunpowder weaponization has not appeared, there are still firecrackers in folklore, as if the Taoist alchemy accidentally discovered simple gunpowder, and later used it in firecrackers.

Firecrackers are used as signal flares during wars, and the so-called cannon sound refers to this.

In fact, people in this world do not know much about gunpowder, and they have not thought of using it in the military. Therefore, Ning Ze's approach, as well as the power of the explosive crossbow, was far beyond their understanding.

After being reminded by Chu Wenxiu, Chu Hong found that the shape of the crossbow arrow in the picture was indeed similar to that of firecrackers, but there were some changes in details.

"The debris also smells like firecrackers. Chu Wenxiu bent down and sniffed, raised his head and said seriously.

Indeed, I didn't pay much attention to it before, but after she reminded her, Chu Hong suddenly remembered that no matter how much the city wall was fighting, or when he withdrew, he smelled something like firecrackers. In fact, it is the smell of gunsmoke, but it is too frightened and chaotic, which leads to ignorance.

But when I thought about it again, I suddenly wondered: "If it is a firecracker, why is there no cannon twister?" At that time, the enemy army was shooting, and no one was seen lighting the crossbow arrows, but attacked directly. The bolt will automatically explode when it touches the shield......"

"Among these fragments, there is something very inconspicuous. Chu Wenxiu's fingers gently twisted a small white stone grain, "At first I thought it was gunpowder powder, but when I think about it carefully, it doesn't seem right!

"Flint?"

"That's right! I suspect that the explosion of the crossbow bolt has nothing to do with the flint!" Chu Wenxiu replied affirmatively, "Such ingenuity is amazing!"

"Gunpowder...... Firecrackers ......" Chu Hong's eyes lit up, "Firecrackers are so powerful......?

"Second uncle, it's not that simple!" Chu Wenxiu shook his head, "Everyone is familiar with firecrackers, and they also know that they are easy to blow up and hurt people." But the power is not yet as great as that of the other party. You see, this crossbow arrow is about the same size as a firecracker, and so is the gunpowder that can be contained in it. But the power of firecrackers is very different from that of crossbow arrows, haven't you thought about why?"

"When you say that, it's true!" Chu Hong frowned, "If we also tie a firecracker and shoot it at the arrow, I'm afraid the power can't be compared with it, and it's good to hurt people." But why?"

"The problem arises on the gunpowder," Chu Wenxiu thought for a while, "I'm afraid that the crossbow arrow gunpowder in Ning Ze's hand is different from ordinary firecracker gunpowder." I don't know what changes he made to make gunpowder more powerful. Also, it's amazing how he can think of igniting gunpowder with flint!"

"Now that you have drawn the drawings, can our army copy them?" Chu Hong asked.

Chu Wenxiu shook his head decisively when he heard this: "Second uncle, my figure is not accurate, it is just restored with fragments, and many of them rely on guessing to fill in the gaps." Moreover, this crossbow bolt has a peculiar shape and is obviously specially made. Not to mention that it cannot be imitated, even if the arrow is imitated and the fire is made with flint, it is the biggest problem that cannot be solved. Not to mention that ordinary firecrackers and gunpowder are afraid that they have no effect. In addition, this kind of arrow has a unique shape, and even if it has the ability to imitate it, I am afraid that it will cost a huge amount of money and cannot afford it! Today, Ning Ze only used one round, and I believe that the enemy army will not easily use it again. ”

Chu Hong was very disappointed: "According to what you say, even if you know how the other party makes this kind of weapon, you can't imitate it? If such a killing weapon can succeed, it may not be able to defeat Ning Ze!"

"That's true," Chu Wenxiu nodded and said, "At least we can dispel the rumors and suppress the rumors that Ning Ze led thunder to bomb the city." Now the people in the city are panicking, and they all say that Ning Ze's mana is strong, and the young envoy can't resist it at all. As long as this rumor is exposed, the morale of the military will be stabilized. Only after stabilizing the morale of the army can we further think about the strategy of retreating from the enemy and not fall into internal chaos. ”

"Makes sense!" Chu Hong immediately said, "There are indeed rumors in the city, and the situation is very unfavorable. The fluctuation of military morale is the most dangerous, and if you can suppress rumors, it will make it easier to defend the city. In this way, you hurry up and write an official document on this matter, and when I write it down, I will immediately go to Yan County Decree and ask him to go to the young envoy to make a speech. ”

"Wenxiu is here to write an official document for the second uncle. Chu Wenxiu replied, "Tomorrow, can the second uncle take Wenxiu to the city wall to have a look? ”

"Nonsense!" Chu Hong was startled and hurriedly said, "Absolutely not." ”

"Second uncle, Wenxiu will change into men's clothes and pretend to be a family member to follow you. ”

"That's not going to work!" Chu Hong said hurriedly, "What if the first-class arrow hurts you, then what can I do? War is not a joke, what are you a girl doing to make a fuss? If something happens, how can I explain to my dead brother and sister-in-law?"

"Second Uncle~"

"No, it's not good!" Chu Hong resolutely objected, "This matter is not negotiable. ”

Chu Wenxiu had no choice but to write out the document first, let Chu Hong memorize the contents, and then he recopied a copy by himself, and went to Yan Tao overnight with the fragments of crossbow arrows.

The stakes were very high, and after Yan Tao learned of the situation, he immediately took him to see Sun Yi.

Chu Hong told Sun Yi about the explosion of the crossbow in person.

It was learned that it was not a spell, but some kind of iron crossbow arrow, which worked on the same principle as firecrackers. Sun Yi's sense of fear weakened a lot, and he praised Chu Hong and rewarded him.

Then he ordered Chu Hong to immediately quell the rumors and stabilize the morale of the army.

The next day, Ning Ze found through the virtual map that the morale of the enemy army, which had fallen to a very low level, showed signs of recovery, and he was puzzled.

According to his thoughts, after yesterday's round of explosions, the soldiers and civilians in the city should panic, and there is no reason for morale to rise.

Just when he was confused, a soldier entered the account: "Report ——! carrier pigeon flying out of Boping City." ”

"Bring it on!"

"Whoa!"

He took the pigeon from the soldier's hand, took the secret letter from the bird's leg, opened it and looked at it, frowning slightly.

It turned out that the superstition wrote: Duwu County ordered Chu Hong, a strategist around him, to post official documents everywhere to appease the army and the people, saying that yesterday's thunder explosion was not an illegal technique, but a special weapon made by the governor. The city severely punishes those who spread rumors, and we can only lie dormant for the time being.

"Chu Hong?" Ning Ze closed his eyes and pondered, revealing a puzzled expression.

In fact, in the first two city gate encounters, he had seen the attributes of the enemy's civil and military officials, starting from Sun Yi to the generals defending the city, not to mention the official and military generals, the attributes were very mediocre. Chu Hong is among them, it stands to reason that this guy doesn't even have the intelligence of 80, and it is impossible to discover the secret of the explosive crossbow in such a short time, let alone even figure out its structure.

There must be a military general with super high intelligence in Boping City, but he did not appear in the main camp.

Ning Ze believed that this explosion of the crossbow was seen and had nothing to do with this military general with super intelligence.

And the long-hooked soldiers who appeared in Duwu County before and were trained on a large scale in Boping also had a direct connection with him.

Judging from the current situation, this military general is either not reused, so he does not appear around Sun Yi, or it is inconvenient to appear.

If he is not reused, why does the matter of the Long Hook Army, as well as the situation of the explosive crossbow, leak out?

But he is reused, and he can confront himself head-on with this wisdom alone, why let Sun Yi suffer again and again?

Every time something is related to Chu Hong, in this way, the military general with high intelligence in the city has a close relationship with Chu Hong.

Chu Hong's subordinates?

Even Chu Hong's subordinates can appear on the city wall, and they can better understand the battle situation and help Chu Hong on the spot.

If it weren't for his subordinates, wouldn't it be relatives?

If it is someone close to Chu Hong, or a child, he is very young. In a protective mentality, it is normal not to let him appear on the battlefield.

Anyway, it's always related to Chu Hong.

I really didn't expect that Liangzhou also had this kind of genius. The explosive crossbow is a weapon that he has carefully researched and worked hard to create, and the other party has actually seen through the secrets.

I wanted to use the explosive crossbow to lower the morale of the city to the bottom, causing internal panic and causing chaos. If the pressure is exerted again, there may be civilian officials and military generals with poor psychological endurance who will become grass on the wall and throw themselves into it in order to survive.

It's just that I didn't expect to be easily punctured by the other party, and the success fell short.

Even though the morale of the defenders was low, they managed to avoid the pressure and did not collapse so easily.

The six counties of Liangzhou are too easy to take, Sun Yi is so straw, Ning Ze originally felt bored, but he didn't expect that there was such a strong opponent in the city. But no matter how good you are, it's really unlucky to face an opponent who has a system to cheat!
