"Mei Daoyou, your firearm is so powerful, can you also pass it on to us?" With a respectful face, Zhuxue stepped forward to ask for it, and the next moment she said:

"Don't worry, Liuli Palace will never take your formula for nothing, you can make a price."

Compared to Ling Shang, the attitude of the woman in front of her was very comfortable, Yan Yunting said with a smile: "The human race against the demon clan, such a righteousness, it is too hurtful to negotiate the price, I don't think it's as good as this, or according to the bounty, all the firearms I made, how about we divide the account of the demon beasts killed?" ”

Isn't it about money?

Pillow Xue sighed lightly: "Do you want to mention another thirty percent on each beast?" ”

Yan Yunting shook his head, "No, no, no, it's me who is seventy percent, and you are thirty percent." ”

"Mei Mingzhi, you still said that you don't talk about money, you're too dark, right?!" Qing Zhi said loudly: "There are hundreds of thousands of demon beasts in the whole territory, if you mention it like this, it can't be ...... That's not ......."

Xu is spirit stone is too much, she can't even count it.

Yan Yunting said indifferently: "I said that the firearms made can be used even by mortals, if you master this craft, you will no longer be afraid of demon beasts in the future." In this way, this firearm is a priceless treasure. ”

Pillow Xue hesitated for a moment, "Or, let's split fifty-fifty?" ”

Yan Yunting smiled, "June Fourth is the lowest, and if you bargain again, I won't give it." ”

"You-"

"Good! 64 open, 64 open! Pillow Xue gritted her teeth and agreed.

The corners of Yan Yunting's mouth curled slightly, "Pillow Snow Fairy, it's much wiser than the one under the city, and I guess it's much more beautiful." ”

Pillow Xue showed a faint smile, "Then when will you be able to give us the recipe for this firearm?" ”

Yan Yunting said: "There's no need to worry, the velvet gourd can only be regarded as a 'burning. Burn. Bottles, we can't call them explosives yet, I'll give them to you when I improve them and finalize the recipe. ”

"Okay," Pillow Xue looked at Qing Zhi, "Qing Zhi, you are familiar with Elder Mei, you bring a few disciples and be responsible for cooperating with Elder Mei's development." ”

"Yes."

……

The burning range of the velvet gourd has reached the expectation, but the power is far from enough, Yan Yunting wants to combine gunpowder with velvet to try the power again.

So, in the first half of the night, he began to refine saltpeter.

"You help me remove the white powder on the nitrate, then mash it all, throw it into the pot, first boil the water over high heat, and then slowly boil it with a simmer, until a layer of milky white foam is boiled, then turn off the fire and cool, if there is no accident, the saltpeter after cooling will condense into yellow-white crystals, then it is fire nitrate; The commission steps for the sulphur mine are similar, and everything is under my command......"

Yan Yunting leaned on the side of the city wall, drinking and directing the female cultivators to work.

"The elders have asked us to help you, but you have used us as servants!" Qing Zhi complained in a low voice, "I've never done such rough work in my life!" ”

Yan Yunting smiled: "It's better than you going down to kill demon beasts, leaving you covered in blood and your life in danger." ”

Qing Zhi said: "I'd rather go down to kill demon beasts, my monks, are you afraid of fighting?" ”

Yan Yunting took a sip of wine and smiled without saying a word.

Although firearms are powerful, they also need to know how to use them, if human generals lead this war, with such a high wall, coupled with ingenious tactics, they will definitely be able to block the tide of beasts; But where did these monks know what tactics of war?

If the beast tide continues to ferment, in the end, you still have to rely on the sword in your hand to fight.

An hour later, the saltpeter and sulphur were purified, and as the night wore on, the temperature plummeted and a snowstorm broke out on the ice sheet.

In less than half an hour, saltpeter and sulfur had solidified and crystallized.

Yan Yunting prepared three kinds of explosives according to the proportion, one was to take fifty percent saltpeter, four percent velvet ointment, and one sulfur; the second is to take sixty percent of saltpeter, three percent of velvet ointment, and one into sulfur; the third is to discard the sulfur, saltpeter and ointment are divided into fifty and fifty;

Then press the middle and upper three layers of the three materials to fill the gourd, and finally add a fire charm to detonate it, so that three simple fire gourds are made.

At this moment, the herd of beasts outside the Great Wall gathered even more densely.

"Let's try it, and remember to cover your ears."

Yan Yunting threw the three fire gourds out of the city wall respectively, and when they were more than a foot away from the ground, they ignited the fire charm in the air-

"Boom!"

"Boom!"

"Boom!"

With three deafening loud noises in a row, the fire gourd exploded in the herd of beasts, the fire was dazzling, and the air waves were monstrous, blowing up the flesh and blood of the demon beasts under the city!

"The fire gourd on the left is even more powerful!" Qing Zhi exclaimed.

"Hmm......" Yan Yunting picked up the book and recorded the data: "Sixty percent of fire nitrate, forty percent of ointment, and one percent of sulfur, the explosives of this ratio are the most powerful, the direct killing range is about ten zhang square, the flame incineration is twenty zhang, and the shock wave is nearly forty zhang...... It was as expected. ”

Then, he recorded the raw materials for making fire gourds, boiled velvet ointment, purified nitrate ore and sulfur, and the proportion of the configuration, and finally signed the end - Batianzong, Mei Mingzhi.

He handed the recipe to Qing Zhi.

Qing Zhi looked at it, and couldn't help covering her mouth and laughing: "Deception Sect? It's a good name...... Bite off more than one can chew. ”

Yan Yunting snorted lightly, "Don't do it yourself? You don't go to Yunmeng Immortal Domain to inquire, ten miles and eight towns, who doesn't know the prestige of my five saints? ”

"You're good." Qingzhi hugged the formula and left happily.

……

In the next three days, all the female nuns of the Liuli Palace joined the ranks of making explosives.

The explosions under the Great Wall of Ice and Snow are getting more and more intense.

The power of the fire gourd is fatal to most demon beasts below the third order.

After three days of bombardment, the corpses of demon beasts under the Great Wall have piled up into mountains, dust mixed with snow and mist, and gunpowder smoke mixed with blood, covering the entire southern border with a thick veil, which cannot be lifted and lingered.

The demon beasts did not retreat under the firearms, but as death spread, more demon beasts poured into the Great Wall of Ice and Snow from the depths of the ice field, and even those herbivorous spirit beasts with gentle temperaments joined the ranks of the beast tide.

Endless killing, instead of solving the root of the problem, will add contradictions and hatred.

There are more and more third-order demon beasts, and their pupils are getting redder and redder.

"This is by no means good news."

Yan Yunting and Li Huai'an no longer drank alcohol, nor did they stop shabu-shabu, the two of them stood in the wind at the head of the city, motionless, one station was a whole night, the snow stained their hair white, the cold ice froze their clothes, but they never shook off for a minute, their expressions were extremely serious, and their eyes were extremely deep.

They all understood that if the ice field was restless, they would not be able to travel to the barbarian realm for a day.

Urgent!

Very urgent!

Very anxious!

"Why don't we go to the Liuli Palace and ask for the help of its palace master?" Yan Yunting proposed.

Li Huaian shook his head slightly, "Even if they can't invite people themselves, why should we run into a wall?" ”

Yan Yunting said in a deep voice: "Do you just keep waiting? This blizzard, unless a key break is found, I am afraid it will be difficult to stop. ”

Li Huai'an was silent for a long time, and finally sighed softly: "Wait a minute, the number and level of demon beasts are getting higher and higher, I think there will be big demon beasts soon, and the Glass Palace should be more eager to find the answer than us." ”

Yan Yunting nodded slightly: "They are the same as us, they have to go to the ice field after all." ”

"Rustling ......" footsteps.

"Who!" The two of them looked back at the same time, shook the snow on their clothes, their eyes were as sharp as knives, and their killing intent fluctuated!

Qing Zhi suddenly lost color, and subconsciously took a few steps back.

"Are you eavesdropping on our conversation?" Yan Yunting said coldly.

Qingzhi hurriedly explained: "I...... I didn't, I just ...... Just ......"

Li Huai'an glanced at Yan Yunting, shook his head slightly, and his voice became warmer: "Fairy Qingzhi, what are you looking for us?" ”

Qing Zhi bowed her head slightly, and said in a low voice: "The elder used the compass to predict that there was a powerful demonic qi approaching the Great Wall ahead, and she asked me to remind you to be on guard......

Yan Yunting turned his head and replied with a light "um".

Qing Zhi glanced up at the two people in the city, bit her soft lips, and turned to leave.
