As for why I didn't buy charcoal, hehe, who is selling it on a hot day now? As for the ones that are sold, they are all fake and shoddy products, so it is better to find some in your own warehouse, which are all high-quality products. Pen & Fun & Pavilion www.biquge.info

He really found three or four hundred catties of charcoal in the warehouse at home, and he took a handful of scales at home, which was mainly used to weigh the proportions.

After entering the small world, he found an open place, or it was all an open place, mainly because he was afraid of burning his few grasses, which were the source of oxygen after all, and now he didn't have time to water them, he couldn't manage his life, and he could manage the grass?

He first put all kinds of items in different categories, and the two phases were far apart, so that even if there was an accident, it would not cause major losses.

Since ancient times, the earth has a gunpowder ratio of one nitrate, two sulfur and three wood carbon, and now make gunpowder according to the experience of the ancients to try, if not, it will be more troublesome.

But before that, the detonating device had to be made, and the phosphorite and paper that I bought before would have a role.

Phospholite is an ore with a low ignition point, about less than 40 degrees Celsius, and it will quickly spontaneously combust when placed in the sun, and is generally used to make fire folds.

He first used a stone mortar to grind all the three catties of phospholite into powder, took out a little powder and evenly smeared it on a piece of paper, and then whisked some flammable materials into a bunch, and put it at one end of the paper to wrap the paper, just such a simple fire fold was made, Nie Yuntian divided it into three sections, he picked up a section and tried to take a breath, and the fire fold sneered and ignited, and the effect was good. Then he made a fire with dry wood.

As for how to ignite the gunpowder, of course, it is directly pointed with a lead, but it is not easy to control the direction of the bomb and the detonation time. But it didn't bother him, and he thought of a simple and easy way.

Put the fire fold on top of a stone, and then bring a stone and press it on one end of the fire fold, he used a rope to tie the flammable material in the middle of the fire fold, and then walked to a distance, pulled the rope violently, the flammable material rubbed the paper to generate heat and finally reached the ignition point of the phosphorite, and the phosphite powder burned and ignited the paper, so that the purpose of igniting the gunpowder could be achieved.

Next was the most important stage of gunpowder, where he first took about a pound of saltpeter, sulfur, and charcoal and ground them into powder for experiments.

Then he weighed one tael of saltpeter, two taels of sulfur, and three taels of charcoal with a scale, mixed them well, and he scooped a spoonful with a spoon, poured it on the ground, and gathered it into a small pile.

Nie Yuntian found a long wooden stick with sparks in the fire, and used sparks to get close to the gunpowder from a distance.

"Bear!" and the gunpowder burst into flames.

"Okay!" Nie Yuntian couldn't help but shout, he succeeded the first time, and Nie Yuntian was very excited. It seems that the experience of the ancients is also very useful.

After that, Nie Yuntian cut the one-foot-long and wide paper evenly into three strips, and then he spread a layer of gunpowder evenly on top of a piece of paper, and then twisted the paper into a strand, so that the fuse was made. He tried to set it on fire, and it worked very well, it burned quickly, if it was fast, if it was too slow, the enemy would run away by the time your bomb exploded.

Then, Nie Yuntian made all the papers into fuses, and he counted twenty of them, all of which were used for experiments.

After making the fuse, there were still about three taels of gunpowder left, Nie Yuntian put all the gunpowder into a fist-sized clay pot, then put the lead in, and then put some stones in the mouth of the can to act as an obstruction, and then passed the exposed lead through the fire fold, tied the fire fold to the body of the can, and then used a rope to tie the flammable material in the middle of the fire fold. In this way, a remotely controlled mine is made.

Then, Nie Yuntian first dug a pit in the ground, carefully buried the clay pot in it, and led the rope into the distance. At the end of the rope, Nie Yuntian carefully lay on the ground, and then pulled the rope violently with his hand.

"Boom!" A few seconds later there was a loud sound, fortunately in a small world, if you were outside you don't know what kind of commotion it would cause.

"It's finally successful!" Nie Yuntian jumped up happily, and he hurriedly ran over to check the results.

When the smoke cleared, a pit about a quarter of a meter deep and half a meter in size appeared on the ground.

Looking at his own achievements on the ground, Nie Yuntian smiled and said, "Masters, your end has come!"

After the success of the ratio of the ancients, Nie Yuntian decided to try other proportions, after all, the things of the two worlds are different, who knows that this ratio is the best?

He spent the next few days experimenting with new proportions in a small world. Don't say it, Nie Yuntian really found an optimal formula, that is, the gunpowder made in the ratio of two nitrates, three sulfurs, and seven charcoal is the most powerful, at least half of the original proportion, it seems that it is still the reason for the aura.

There is still a little bit of this world more or less, just like the earth is simply poor.

He spent the next few days making new gunpowder in it, and finally obtained about two hundred catties of finished gunpowder, and now everything is ready, only the shell is owed.

However, he still used clay pots to make a few simple bombs to defend himself, who knows when the crisis will come? Fortunately, they haven't taken any action in the past few days, it seems that they are also afraid of attracting Huang Yuanlong's attention too often, as for Huang Yuntian, they don't care at all, what can this little kid see? If it weren't for being valued by Huang Yuanlong because he was so young and a third-rate martial artist, he would have been killed long ago. But what they don't know is that this Huang Yuntian is no longer the Huang Yuntian who was at the mercy of others.

Ten days later, he went out again, this time Nie Yuntian brought back the two hundred iron shells he had prescribed, and he also bought more phospholite, paper, sulfur, saltpeter, charcoal, and some flammable materials, and used thousands of taels of silver, which made him very distressed, and no matter how rich he was, he couldn't afford such an expense.

Everything else is easy to buy, there are ready-made ones in the city, and charcoal is what he has ordered, after all, there is no good charcoal now. The charcoal seller wondered what he was doing on this hot day, but he quickly burned the charcoal, driven by money.

He also got a message, you said that the woman named Xiaoqian disappeared for no reason. It seems that she was afraid that they would kill people and kill them, so she ran away early. This has nothing to do with him, taking people's money to eliminate disasters for others, and if you don't eliminate disasters, you have to pay a price, and her price is obviously her life, and she is not willing to give her life and run, which is also a correct choice.

Back at home, Nie Yuntian assembled all the bombs and tried a fist-sized bomb, which directly blew the hard ground into a pit half a meter deep and one meter long and wide. He didn't try it, he was afraid that the world would be blown up, who knows if this space is stable or not, if it causes the butterfly effect to cause the space to shatter, he will die on the spot, and there is no place to reason. What's more, this is no ordinary "butterfly".

……

Nie Yuntian's bombs are all made during the day, and at night he still enters the dream realm to train his combat ability, mainly knife skills. Although his strength has increased, the strength of the enemies in the dream realm has also increased, just enough for him to train. A dynamic equilibrium is maintained.

In this way, a month has passed, Nie Yuntian's sword skills have grown very rapidly, and he no longer only understands the left and right Du sweeps like he did at the beginning, and combined with some classics such as knife books in their family, he has a good look.

Huang Yunhu and the others didn't have any other movements, but even if they did something, he was not afraid.

……

In a courtyard of the Tianlong Dart Bureau, two figures were talking. "Big brother, last time Huang Yuntian's kid somehow escaped, and let us waste so much energy and money, but didn't cause him any loss. A figure said in annoyance.

"Hmph, this time he won't have so much luck, let him die like his parents, and send him to reunite with his parents. With that, the two figures disappeared into the darkness.

As soon as it dawned the next morning, Nie Yuntian was called by Huang Yuanlong.

Nie Yuntian also wondered what Huang Yuanlong was looking for him for, he usually came to him when there was something. But he didn't pay much attention to it, after all, he was an elder.
