"W-what is this?"

The demon clan who controlled the beast tide couldn't help but widen their eyes for a moment as they watched the beasts under the city wall fall down in pieces like wheat under the iron ball.

"Is this a new weapon made by humans? Why is the power so terrifying, I feel that even my physical body may not be able to bear it. ”

A demon muttered to himself.

"Quick! Tell the king about this, and ask if he can send out the birds of prey. Another demon commanded.

At this time, the wolf force in the rear had actually noticed the changes under the city wall.

He was far from the city walls, but the loud and continuous explosions reached his ears.

"What's going on? Could it be that humans have used the so-called psionic cannon? ”

Wolf Li sat up, his face suspicious.

When Jiuli said that the demon king was moved, he naturally informed the demon clan of the invention of the psionic cannon, and at the same time leaked the strength of Jinling and Heishui City.

Therefore, the wolf force thought that the previous rumble was the roar of the psionic cannon.

But he thought about it, and felt that it was unlikely, according to Jiuli's information, it was impossible for Jinling City to have so many psionic cannons, and the sound just now seemed to be much smaller than the sound described by Jiuli.

Of course, he wasn't so sure, after all, he hadn't seen the psionic cannon fire with his own eyes.

"Report!" At this time, a demon clan rushed back from the front line and said, "Great King, the human race has used an iron ball weapon that we have not seen before, which has dealt a great blow to the beast tide, and the commander asked the small one to ask for instructions on whether to send out the birds of prey to cooperate with the beast tide." ”

Wolf Li pulled his palm out of the collar of the woman next to him, touched the tip of his nose, and said: "There is no need to dispatch birds of prey, those are used by this king to attack the city, tell them, continue to increase the impact of the beast tide, and be sure to use the corpse to build a passage to the city wall for the king's army before dawn!" ”

The current attack has only one purpose, that is, to build a road to the city, and there are not many birds of prey under his command, so it cannot be wasted at this time.

After all, their purpose this time was to destroy Jinling City, not to kill how many cultivators in Jinling City.

Good steel has to be used on the blade, and those birds of prey were gathered by him with a lot of effort, in order to cooperate with the attack of the demon army under his command.

"Yes, the little one understands."

......

On the walls of Jinling.

Gongsun Keming and Dongfang Yue were looking at Qin Chuan with amazement.

"Sect Master Qin, what kind of magic weapon is this thing, why is it so powerful, why have I never heard of the name of this thing."

Dongfang Yue held a grenade in her hand, and kept stroking the smooth and cold sphere, looking at it as if she was admiring some beautiful jade.

Gongsun Keming didn't look like him, but he also looked at the grenade in his hand with a surprised face.

"Brother Qin, what is the black powder in here, why do I feel that the things in it seem to be some common things?"

He had secretly disassembled a grenade and found that it was very simple in construction, with an iron shell on the outside and powder inside.

And although he didn't know what these powders were, he could feel that the ingredients in them were all minerals that didn't make up their minds.

This can't help but shock, it's just some mortal things, and then put on an iron shell, it can burst out with a power similar to palm thunder, and this thing doesn't have the slightest technical content to use, take a little fire fold, and it's over.

Isn't this even an ordinary person able to threaten cultivators?

"I named this thing a grenade."

Qin Chuan took the grenade in Dongfang Yue's hand, lit the fuse casually, and threw it under the city wall.

When the grenade exploded, Qin Chuan smiled slightly and said, "This is filled with gunpowder that I researched, this thing has explosive properties, as long as a little spark can make it burn in an instant, and then explode." ”

"Gunpowder?"

Gongsun Keming and the two frowned at the same time, thinking to themselves what this gunpowder was, could it be some kind of exclusive secret recipe of the Seven Star Sect?

Seeing that the two of them still wanted to get to the root of the problem, Qin Chuan waved his hand directly and said: "Two, now is not the time to ask the truth, let's deal with the beast tide in front of you first, and when the gambling agreement between the Demon Emperor and the imperial court is over, I will talk to you in detail, and when the time comes, I promise to know everything and say everything." ”

Seeing him say this, the two of them also suppressed their desire for knowledge.

"Okay, let's deal with the beast tide in front of you first."

Dongfang Yue said a word and left, and Gongsun Keming didn't have the heart to continue eating.

After he put away the food box, he turned his head to look at the boundless beast tide outside the city, and he was still very worried in his heart.

Although with the Qinchuan grenade, the people in the city will no longer be consumed by the beast tide, but this time the beast tide, the real danger is still the 10,000 demon army.

And in the same realm, the demon clan is stronger than the human cultivators, not to mention that those demon armies are all building a foundation realm, and with the demon slaying on this city wall, they can't resist it at all.

"Brother Gongsun, what are you thinking, are you worried about the 10,000 demon army?"

Seeing that he was distracted, Qin Chuan smiled and patted the former's shoulder.

Gongsun Keming nodded and said, "That 10,000 demon army is the real danger this time, and although the Jinling City Demon Slaying Division has been replenished after the last Jiuli disaster, most of them are newcomers to the Qi Refining Realm, and I am afraid it will be difficult to resist those demon armies." ”

Jinling and Heishui City, after the Jiuli Disaster, did receive rewards from the imperial court, but the personnel could only be recruited by Jinling City itself.

The total number of Jinling City is so big, and the previous Demon Slayer Si Si Zhong has already selected almost all the right people, so this time the manpower is replenished, and basically all of them are newcomers to the Qi Refining Realm.

Although there are many cultivation resources in the court's reward, the cultivation realm is not something that can be improved in a short period of time with cultivation resources.

Therefore, half of the people in Jinling City's Demon Slaying Division are now in the Qi Refining Realm.

"Hehe, Brother Gongsun doesn't need to worry."

Qin Chuan smiled and said confidently: "Since the grenade can be quickly manufactured in batches, Jinling City has been invincible, unless his demon clan makes a move in the Yuanying Realm, he will not want to destroy our Jinling City." ”

As soon as these words came out, Gongsun Keming's heart suddenly shook, and he hurriedly asked: "Brother Qin, could it be that in addition to this grenade, gunpowder can exert greater power?" ”

Gongsun Keming was very smart, and after a little thought, he guessed what Qin Chuan meant.

"Hehe, everything will be known when the time comes."

Qin Chuan didn't answer him directly, but sold a pass, when he left the Demon Slaying Division, he had already told those refiners all about the artillery and the explosive bag and the like, about the weapons that gunpowder could be made.

Although the refiners of this world may not be able to understand this knowledge, he believes that those refiners will definitely be able to create those great killing weapons in the previous life.

......

Jinling Demon Slayer Division.

Dozens of highly respected refiners in Jinling City are in full swing forging firearms from their previous lives with their own unique refining techniques and according to the drawings left by Qin Chuan.

And in the square of the Demon Slayer Division, Xu Wanyi was speechless and looked at a giant grenade in front of him that was the same height as him.

This thing was transformed by a refiner based on Qin Chuan's grenade, not only did it increase the volume of the grenade, but even the outer iron shell was replaced with a second-order material.

But who knows if the power of this gunpowder can explode the second-order material, and the size and weight of this thing are also too great, and it is impossible to throw him out with those who are generally only in the foundation building and qi refining realm.

"Master Xu, I have tested it many times, the kind of gunpowder that Sect Master Qin configured can definitely explode this second-order material, but the specific power of this giant grenade still needs to be tested, so see if you can ...... it"

The maker of the giant grenade was a little obscene-looking little old man, and at this moment he was eagerly taking out a fire fold from his arms, and he wanted to light the fuse of the giant grenade.

it!

Looking at the movements of the little old man beside him, who was respectfully known as Master Jia, Xu Wanyi hurriedly snatched the fire fold in the other party's hand and threw it into his space ring.

"It is said that the refiner and the alchemist are a bunch of crazy people, and that's true!"

Xu Wanyi scolded secretly in his heart, and couldn't help but be glad that his reaction was fast enough.

Although the grenade he made earlier was not enough to threaten his Jindan Realm overhaul, who dared to guarantee that this thing in front of him would not hurt him, if he was ordered by this madman, then he would still have it?

Even if it didn't hurt him, he estimated that if it exploded, all the houses around it would be razed to the ground.

"Master Jia, you are not allowed to test this thing in this city, if you really want to test it, I will help you arrange for this grenade to be sent outside the city."

Xu Wanyi saw that he was unwilling, for fear that he would take out a fire fold from his arms again, but fortunately, he directly contacted Qin Chuan with the shadow jade and asked the latter to come back.

This giant grenade was too heavy, and the power must be terrifying, he didn't dare to let this thing explode under the city wall, so the best way was to let Qin Chuan fly out of the city wall with a spirit boat, and then throw it into the beast tide.

After a while, Qin Chuan drove the spirit boat and landed.

"I'll go! What are you guys doing, why are you so big! ”

As soon as Qin Chuan jumped down from the spirit boat, his eyes were attracted by the giant grenade.

He remembered that the drawings he gave didn't have such big guys, could it be that those refiners diverged their thinking and made up their own?

And looking at it like this, this giant grenade is not made of ordinary materials, it seems to be a second-order material.

"Master Xu, who made this thing, can this explode?"

He looked at Xu Wanyi suspiciously, although he knew that the power of gunpowder was very strong, but there were all kinds of strange metals in this world, and no matter how powerful gunpowder was, it might not be able to explode these metals.

Before Xu Wanyi could speak, Qin Chuan felt that his hands were being held, and as soon as he turned his head, he noticed that in addition to Xu Wanyi, there was also a lewd little old man here.

"Presumably, Your Excellency is the Qin Sect Master of the Seven Star Sect, in Xia Jia Ren, he is a third-grade refiner."

Master Jia looked at Qin Chuan with admiration on his face, and he felt uncomfortable for a while.

"Hello Master Jia, I'm Qin Chuan." He withdrew his hand without a trace, and then asked, "Master Jia, did you make this thing?" Are you sure this thing can explode? ”

Jia Ren nodded, and swore solemnly: "Sect Master Qin, rest assured, I have done a lot of experiments in making this giant grenade, and I can guarantee that this thing can definitely explode, and its power should be very terrifying." ”

"Since Master Jia is confident, then you can give it a try."

Seeing that Jia Ren was full of confidence, Qin Chuan did not hesitate, and directly put the giant grenade into his space ring, and then took Jia Ren to step on the spirit boat together.

"By the way, Master Xu, don't forget to tell Blackwater City how to make this gunpowder and grenade, the pressure on their side is greater than ours, and they must need this thing more."

Before leaving, Qin Chuan suddenly remembered.

"Don't worry, I don't need you to tell you, I've already informed you"

Xu Wanyi smiled slightly, and he was all in control, but after Qin Chuan Lingzhou disappeared into the sky, his face changed, and he hurriedly used the Shadow Jade to contact Hong Lie in Blackwater City.

"Master Hong, we have just gotten a ...... in Jinling City."
