"Beware!"

Suddenly, Zhang Qizhi shouted loudly.

Qi Zhaoruo's eyes were quick, and he immediately protected Fu Nianjun and squatted down.

This was the second shell fired by the Tanguts.

The walls shook again.

Fu Nianjun looked sideways at Qi Zhaoruo beside him, and saw that he was also half relieved.

If it was real artillery, they wouldn't have to fight this battle at all.

Just two shots are enough to blast through the thick city walls.

And now, the iron projectiles of the Tanguts only played the role of impact, that is, their artillery only had an empty shelf, at best a more powerful catapult, which could only play a threatening role.

"You go down first. ”

Qi Zhaoruo thoughtfully protected Fu Nianjun with his hand and went down the city wall.

"This thing appeared in the hands of the Tangut people because of ......"

Fu Nianjun was about to speak, but was interrupted by Qi Zhaoruo.

"Because the people behind the scenes betrayed the country. ”

He briefly came to a conclusion, and then glanced at Fu Nianjun: "Who is he, please tell me after you pass this level, but now, my personal grudge is not as important as the safety of Dunzhou City at this moment." ”

He didn't want to be distracted.

Fu Nianjun nodded, and then said, "Fortunately, he didn't master the secret recipe for gunpowder, otherwise the consequences would be really unimaginable." ”

In fact, even after thirty years, the Song army did not dare to use artillery, and most of them were locked in the reserve.

The reason is also well understood, too dangerous.

On several occasions, the shells did not go out, but killed the surrounding soldiers, not to mention the particularity of gunpowder, it is difficult to transport it over a long distance, and the two armies are fighting, to put it mildly, the enemy only needs to send a small out, a little spark, can blow up half of their own camp, so even after thirty years, artillery is not the first choice of the Song army, to control this weapon, it will take a long process to perfect all aspects of preparation.

It's Zhou Shaoyong who is too anxious.

"Even then, we'll have to destroy that thing quickly. ”

Qi Zhaoruo twisted his eyebrows and said:

"Although the power of this cannon is less than one-tenth of that of later generations, in view of the fact that our garrison is so poor, I personally went to see the city wall a few days ago, and the construction site is really poor, and if the iron projectiles keep hitting, it is very easy to form a collapse. ”

Therefore, the enemy's armament is not high, but our army is even worse.

Fu Nianjun secretly hated this corrupt official who was on the border defense of the Great Song Dynasty, and dared to cut corners for such a big thing as building a city.

"Iron projectiles are expensive, and I don't think they're going to attack all the time," she said. ”

After a pause, he said: "If my guess is correct, this thing was originally a killer weapon that was sacrificed when it was going to be pulled to deal with Weizhou, but now they see that it is difficult to attack in Yanzhou, so they simply pull it out and walk it first." ”

From this point of view, this Western Xia lord is also a person who can't hold his breath.

Qi Zhaoruo nodded and glanced at Fu Nianjun: "Do you have a way?"

Fu Nianjun smiled bitterly, "Count it as half a method, because I'm not sure at all." ”

Qi Zhaoruo spit out a comforting word: "From the very beginning of this siege battle, no one was sure. ”

Fu Nianjun exhaled: "I'll try, but please be sure to keep it." ”

Qi Zhaoruo smiled, and there were two more points of youthful spirit and confidence in his smile.

"It's nature. ”

After all, he boasted about Haikou.

"The iron projectiles of the Tangut people will not be wasted too much in Dunzhou, so I think if you are a little more ...... with this artillery. Be horrified, and maybe they'll use it less. ”

Fu Nianjun said his advice:

"Of course, if you think this is detrimental to the prestige of our army, I don't say it. ”

Defending the city is Qi Zhaoruo's business, Fu Nianjun has no command power, and what Qi Zhaoruo should do is his own decision.

Fu Nianjun hurry up, she needs to put the ideas in her head into action as soon as possible.

Thirty years later, the Great Song Dynasty, firearms manufacturing has made great progress, Fu Nianjun thanked himself for his habit of reading idle books in the past, this idle book is not only the market book, but even includes the "General Essentials of the Martial Arts" on firearms manufacturing, and Fu Ning has never restricted her in this regard.

It was too complex for her to build a weapon from her memory in a short period of time.

But there is one thing, but it is possible - "thistle".

Tribulus terrestris is mixed with prepared gunpowder, with iron tablets and other lethal substances, as well as poisonous tribulus terrestris, and solidified into a spherical shell with multi-layer paper paste, and the shell is coated with flammable ignition material, and then used after drying.

She once lamented that the person who invented this thing must be an all-rounder, not only understanding weapons, but also pharmacology.

Of course, it is impossible to compare the power of fire thistle with artillery, and when the two armies are fighting, it is also burned as an obstacle and a shield, although the damage is not huge, but for the time being, it is very suitable.

Because the weather is beautiful, the southeast wind has been boasted since last night.

And the Western Xia army is just downwind, which means that the smoke after the burning of the thistle terrestris will have an exponential effect due to the direction of today's wind.

Without further ado, Fu Nianjun mobilized the women in the city and began to make thistles from the tribulus grass that had already been collected.

Gunpowder is no way to conjure up at this time no matter what, Fu Nianjun has already thought of countermeasures, there are fireworks and firecrackers shops in the city, and there are a lot of firecracker shops to be used in the New Year and New Year, and now they can be requisitioned together.

Firecrackers mainly contain nitrate, dirt and other substances, which are still very different from gunpowder, but the smoke and loud noise produced are enough.

After Fu Nianjun saw the artillery of the Tangut people just now, she guessed that in fact, Zhou Shaoyong's idea was the same, the smoke was billowing in front of the Tangut people, maybe they also borrowed fireworks and firecrackers to increase the power of the "artillery", but because this thing was used by the Song people, the Tangut people marched for a long time, and it often snowed on the road these days, and the firecrackers and fireworks with the army must be damp, so the sound when firing the cannon was not loud, but the smoke was huge.

Fu Nianjun also got some inspiration from this, and immediately ordered the women in the city to urgently make thistle with her.

Since she didn't have enough time, it was impossible to improve the workmanship, so she used paper and wax to seal it, and after a short explanation, the skillful women were immediately able to complete the simple tribulus terrestris.

But the question also followed, tribulus terrestris is not a commonly used medicinal material after all, and the reserves in the city are really limited, Fu Nianjun is eclectic and asks everyone, but as long as it can play the same role, you can try to add it to the fire tribulus.

The shopkeeper of a few herb shops offered some herbs, and some peasant women said that they could try the bellflower because the black smoke from its burning was extremely choking.

Fu Nianjun adopted them all.

In the end, which one is easy to use, she has no time to verify, so she can only hand it over to the battlefield.
