As the saying goes, one sulfur, two nitrates and three charcoals, which is an important part of black **.

Find the sulfur, and the guy who made the black ** is all about it! Next, as long as the ratio is good, you can do the experiment.

Mo Lan instructed the others to continue their search for sulfur, and she took the collected sulfur down to the high ground, found a safe place outside the high ground, and began to mix the powder.

To be on the safe side, she didn't mix much powder for the first time.

She took out the saltpeter powder, sulfur powder, and charcoal powder, carefully put them into her small balance made of moso bamboo, and began to weigh them.

At this moment, Yuga walked over and saw the strange small dish of ground wool bamboo that swayed up and down in front of Mo Lan, and was immediately attracted! Curiously, he stepped forward and asked, "Mo Lan, what is this?" ”

"A scale, which is used to weigh the mass of an item."

Mo Lan was busy mixing various powders and replied casually.

"Scales? How is it weighed? How do you know how much it weighs? ”

Yuga asked with an interested expression.

Mo Lan had no choice but to explain in detail: "A balance is a weighing instrument, an instrument used to measure the mass of an object. It is made according to the principle of the equal-arm lever. At each end of the lever there is a small tray for the object to be weighed. For example, sulfur powder, or saltpeter powder. ”

Mo Lan said as she pointed to the small bamboo plates at both ends of the scale.

"Actually, in our place, the tray at one end of the scale is used to hold weights, and the other end is used to put the object to be weighed. A weight is a standard gauge that allows us to know what the mass of an object is. But we don't have that condition yet, so we can only put objects in both plates. ”

Mo Lan said, using a small shovel to put the sulfur powder and saltpeter powder into two small dishes, and began to weigh them.

"See this pointer? When the pointer in the center of the lever coincides with the line in the middle, the two ends are balanced, and the mass of the object at both ends is the same. Conversely, if the small dish at one end sinks and the pointer tilts, it means that the objects on both sides are of unequal mass. ”

Mo Lan explained, using small bamboo slices to gently add or subtract saltpeter and sulfur powder from the small plates, and finally the pointer finally coincided with the center line, and it seemed that the sulfur powder and saltpeter powder in the two small dishes were basically the same.

"It's amazing! Mo Lan, your Yan Clan's things are really exquisite! ”

Yuga understood the truth and couldn't help but sigh.

Mo Lan smiled and said, "Our Yan clan has a lot of more subtle things than this, I will teach you them one by one when I have time in the future!" ”

"Really? That's great! ”

When He heard this, he was suddenly surprised.

The Yan civilization on Mo Lan's body is really breathtaking, if you can learn two or three out of ten from her, you can use it endlessly!

Mo Lan just smiled lightly.

The cultural heritage of the Chinese nation is broad and profound, and it is a precious wealth that many working people have exchanged for blood, tears and sweat, and the essence of five thousand years, which is of course a supreme treasure for these orcs.

Yuga studied medicine, and through medicine he learned more about civilization. Mo Lan estimated that Yuga's mind should have reached the stage of enlightenment. And Han Che, it is estimated that it is likely to be in the late stage of Qihui, or close to wisdom to keep pace with her!

Because every time she told him something new, he was always quick to accept it, and he understood and comprehended it quite quickly and thoroughly.

If it weren't for his naturally high IQ, then it could only be said that his mind was already enlightened!

Between the turns of his mind, Mo Lan has completed the ratio of black **. Now it's time for the real experiment!

This time, Mo Lan has to test two kinds of weapons, the first animal skin, which is the kind she used to deal with the ground brown bear. The most important thing is not the power of the explosion, but the aftermath of the explosion

The second type, bamboo tube**. This is similar to the production method of firecrackers, but the ground bamboo is thick, and Mo Lan added flammable materials and gravel to the bamboo tube, which should be able to reach more than ten times the power of firecrackers after improvement. It's not an exaggeration to say it's small**. In this Kumo Snow Plain, where conditions are extremely scarce, this is already the strongest weapon that Mo Lan can find and successfully develop!

Although this is only a simple **, Mo Lan is confident that he can definitely become a powerful help for the clansmen when hunting!

Mo Lan communicated with Xiaoxiao in her heart for a while, and after repeatedly confirming that there was no mistake in the production method, she picked up the prepared animal skin** and bamboo tube**, and put them in the right place according to their different characteristics.

Because it was the first test, Mo Lan made the fuse slightly longer so as not to injure himself by mistake.

"Mo Lan, are you going to start? I'll help you! ”

Yuga followed, with a look of eagerness.

Mo Lan replied solemnly: "No, this thing is too dangerous, maybe something will go wrong!" You stand back, I'll come! ”

Seeing that Mo Lan's face was so solemn, Yuhe didn't dare to disobey, and with a wave of his hand, the group of clansmen who came over with curiosity retreated to a safe distance.

After everyone obeyed and stayed away, Mo Lan took a deep breath and summoned a little pet in his heart.

Little.

Master, little is here!

The little yellow dog immediately appeared in her mind.

Are you sure it's okay? Mo Lan was apprehensive.

After all, this thing is different from other weapons, the lethality is too great, if it is really injured by mistake, with the current level of medical care, it is really certain death!

Don't worry, master, I've checked it, two simple ** are no problem, you can test it with peace of mind!

Little flapped her furry belly with her wings.

Okay, then I'm relieved!

After a little invisibility, Mo Lan stepped forward and took out the reserved fire and lit the fuse of the animal skin.

Seeing the fuse slowly burning, Mo Lan immediately got up, quickly retreated to a safe distance, half-squatted down, supported the ground with one hand, and stared at the fuse tightly.

As the fuse burned out, there was a loud bang, and the animal skin** was detonated into a fireball, and then a wave of fire swept in the form of ripples!

Seeing this, Mo Lan's face changed, and he turned back to Yuga and the others and shouted, "Get down!" ”

Yuga and the others were stunned by the power of this animal skin**, and they hurriedly crawled to the ground when they heard Mo Lan's shout!

Just as they were lying down, a wave of heat rushed over their heads, and everyone was collectively scared into a cold sweat!

Looking up again, everyone found that a pit was blown out of the place where the animal skin ** was placed, and all the weeds around it had been turned to ashes.

"Oh my God, that's too good, isn't it?"

The clansmen who came with them were all stunned and in disbelief.

If someone had stood in the place of the explosion at that time, they would not have been burned to charcoal!

Mo Lan saw that the experiment was successful, so he got up, went over to check, and saw that the animal skin ** was exactly as described in a small way, so he nodded with satisfaction.

"Mo Lan, is this the power of **? It's horrible! If this is thrown on a man, that person will surely die! ”

Mo Lan glanced at him and said solemnly: "This is not too powerful, and the next one is even more fierce!" Stand back, and I'm going to keep trying! ”

Yuga hurriedly beckoned the clansmen to retreat half a distance, and then squatted down and looked at Mo Lan.
