"Black burst powder" is just traditional gunpowder, and after mastering the configuration method, it is not too troublesome to operate.

However, after all, Morrow is a person researching, and the configuration method is not very efficient, especially the production of saltpeter, which he grinds out of nitrate, and a lot of effort is spent on it.

Nitroclide rock is a commonly used material, which is generally used in a specific source box, and is one of the important ingredients of a source box agent, so the price of pure nitrified rock is expensive, and Moreau's budget on materials is mainly spent on this.

Xia Yu quickly understood Mo Luo's train of thought.

In the latest "black burst powder" formula, charcoal and sulfur powder are almost equal in proportion, accounting for about one-fifth each, followed by saltpeter, and a small amount of mercury.

He also looked at Moreau's previous test data, and the effect was really good.

"There is no such saltpeter sold in the shops outside?" Xia Yu asked.

"Yes, nitrification rock is relatively commonly used, so it can be bought in large quantities, and several other raw materials that can produce nitrate are rare, so don't think about it!"

"Understood," Xia Yu dispelled this thought, and asked again, "Then what am I here for?"

"Let's just extract saltpeter, this is the most time-consuming step, and I still have some stock that can be configured simultaneously. Well, the extraction is mainly carried out with this crushing and purifier, and a little catalyst is added...... "Mo Luo made a demonstration and explained the key steps in detail, and Xia Yu listened very carefully.

The principle of this crushing and purification instrument is not difficult, mainly three steps of crushing, filtration and purification, but it is easy to retain impurities, which will affect the effect of "black burst powder".

Xia Yu roughly understood the operation method, and then waved his hand directly: "You go, leave it to me here, I will put it in the sand jar in front after extraction, you can pick it up at any time." ”

"Well, this crushing and purification instrument has relatively high requirements for perception, you can try it first, don't worry!" Moreau reminded.

Demanding perception?

I don't think so!

Understanding the control method of this instrument, Xia Yu quickly entered the state, because he was in a hurry, he directly mobilized all 21 sensing tentacles and felt the use of this instrument.

Next, he added a catalyst given by Morrow and began to filter and purify with a sensory manipulation instrument.

This is a meticulous job, because this instrument is not very automated, and almost every step of the operation needs to be controlled by human perception and mobilization, triggering the source energy to work, which is completely different from the more and more automated and fool-like operation on the earth.

Considering the design of this instrument and the fact that the users were all mechanism cultivators with a certain level of perception, Xia Yu was quickly relieved.

However, Xia Yu was not difficult this time, while he accurately controlled the perception and felt the filtration and purification process of the saltpeter powder in this instrument, he inadvertently sped up the speed......

"Hey, don't be so fast, saltpeter is the most critical material, if the purity is not enough, it will directly affect the effect of the black burst powder......" Ten minutes later, Mo Luo got the equal amount of black burst powder in his hand, turned around to see that Xia Yu added the catalyst too fast, and couldn't help but remind.

In his experiments, the purity of saltpeter is indeed the key element in the explosive power of black burst powder, and basically only more than 98% of the purity can meet his requirements.

His own perception is very strong, but it takes about ten minutes to complete it, and he can purify 200 grams of 98% pure saltpeter at a guaranteed purity, and sometimes even 98.5%.

Xia Yu's first operation, he didn't plan to use it directly, he always had to be familiar with the instrument and test it a few times before it could reach the point where it was usable.

"Oh?" Xia Yu stopped and handed a small jar next to him to Mo Luo: "I didn't test it, but it feels like it should be okay, can you use it if you try it?"

"What? You've already finished one, hey, even if you're in a hurry, you can't ignore purity, isn't that a waste of raw materials......" Moreau frowned.

"Eh, do you want to test the purity first?" Xia Yu was still very confident in his operation.

The most important thing is that you need to pay close attention to the morphology, granularity, and adhesion state of saltpeter powder in the purification process, so the fineness of perception is very high.

"Hey, you really can't do this......" Mo Luo muttered, he was used to living a poor life, he naturally couldn't stand Xia Yu wasting materials like this.

However, after a few seconds, his mouth grew big, and he pointed at Xia Yu incredulously: "You...... How did you do that, boy? You're a fucking demon!"

No wonder he was surprised, because the numbers on the monitor clearly showed that the purity of the saltpeter powder produced by Xia Yu, the demon, for the first time, had reached 99.8%!

That's right, 99.8%!

It's a little higher than your best!

"Can it be used?" Xia Yu didn't look up at all, and continued to purify the second saltpeter.

"Yes, of course it works!" Morrow's eyes lit up, and he said excitedly: "I don't know how you did it, but the higher the purity, the better the effect of black powder, even if you get it, 20 pounds, maybe we can really get it tonight!"

............

The seventeenth day of the first month is an ordinary day.

The huge Luotong City, because of the recent turmoil, many people died in the melee every day, but this time the city lord seemed to lose his voice, allowing the situation to fall into erosion, it seems that in addition to the previous ban on 3-star monks to shoot in the city, ordinary battles are not taken into his eyes at all.

In these melees, there are monks who soar overnight, and there are also poor people who bury their bones on the battlefield without being rewarded.

For the veteran and wealthy families behind many monks, what does the life and death of these ordinary monks have to do with themselves?

The singing and dancing are still peaceful, and the singing and singing are non-stop every day, this is the bearing of the wealthy.

Zhang Luosheng didn't have this interest, but he couldn't stand his wife's insistence on Chong Chongxi, and a group of old friends also wanted to get together on this day to discuss the current chaotic situation, so he reluctantly made it difficult.

It's just that now sitting in the highest attic within a radius of several miles, looking at the brightly lit Zhang Mansion, as well as the shops and houses in the old town of Anyang, where every inch of land is valuable, it is obviously calm, but he always feels a sense of panic coming out of his heart.

What could happen?

Qu Bailing's side did not receive instructions not to do it without permission, and if he really wanted to do it, the strength of the Zhang family was not enough.

It can't be which Xia Yu?

The 3 henchmen discharged by themselves are all experienced 3-star powerhouses, and they are still part of the hole cards left by their father back then, although there is no news back yet, but nothing will go wrong after all, right......

Anyway, this feeling was very uncomfortable, and he was a little stunned for a while.

"Master, master......"

A concubine waited to call him to prepare in the front hall, and when she saw him like this, she didn't dare to rush up directly to disturb him, so she had to keep calling at the door.

"Oh, it's Ah Luan, who has arrived?" Zhang Luosheng came back to his senses and tried to suppress the uneasiness in his heart.

"The four principals of Article 17, several elders of the Chongyang Old Mansion, as well as many representatives of the Chamber of Commerce, the head of the monk group, there are no less than 100 guests, and the eldest son and the second prince are also well received, but the Duan family, the An family, the Hong family and other family heads are about to arrive, and the eldest lady asks you to call you to the door of the outer house to greet you......"

"I know, you go back first!" Zhang Luosheng waved his hand and glanced at the concubine more.

Well, it's been ten years, it's my own fame battle, soft and hard, and I will completely knock a rival family into the abyss in a week and can't turn over, and this rival's favorite woman is naturally included in the house.

Ten years have passed, and this woman is still charming, but she is a little old.

"Xiaoluan, wait a minute......" He was shocked, regained a lot of ambition, and stepped forward to hold the hand of the pretty woman in her early thirties: "Don't go, come with me to the front hall......"
