When the new gunpowder is made, it can be used for four purposes.

First, it can be used to make guns and shells, which can hit the enemy at close and long distances, and is very beneficial to individual combat and group combat, but according to the current scientific level and production conditions, it is obvious that it cannot be manufactured. This use can only be used as a long-term plan, and it cannot be realized at present.

Second, it can be used to make explosive packs, which are used to destroy castles and other buildings, and are a good blasting weapon, which can destroy decay, and the technical content of its production is not high, and it can be easily mass-produced. If there is an opportunity, Wu Zhi intends to mass-produce it when necessary, which can be used to equip troops and attack the city.

Third, it can be used to make grenades and grenades, which can kill and injure the enemy in a large area at a relatively close range, and the deterrent effect is also good. For Wu Zhi, this is the most ideal weapon at the moment.

Fourth, it can be used to make new rockets, bundled new rockets, that is, crossbow arrows can be tied to new gunpowder or weapons made of new gunpowder, launched through a powerful bed crossbow, can be remotely delivered to the enemy camp for long-range strikes, is a good long-range kill weapon, as long as the crossbow arrow is slightly modified, this is a good choice direction. If there is an opportunity, Wu Zhi will try his best to use this new rocket to equip the Song Dynasty army and enhance the long-range strike capability of the Song Dynasty forbidden army.

Based on reality, there are only two options that Wu Zhi can do at present, one is to make explosive packs, and the other is to make grenades or grenades. The explosives package is too big to carry, and Wu Zhi has no chance to destroy the city at present, so the explosives package is not needed for the time being. The only option is to make grenades or grenades.

Hand grenades are relatively small in size, light in weight, easy to use, easy to carry, and relatively hidden, and they are also very powerful, much better than knives, guns and sticks, and can be manufactured with the knowledge level of Wu Zhi and the current conditions. Therefore, making grenades or grenades has become the only choice for Wu Zhi.

Wu Zhi thought about it again and again and decided to make a grenade, a simple version of a bamboo grenade!

So, Wu Zhi found a sharp machete, ran to the back mountain (low hill) and cut a few bamboos about an inch and a half thick, the thickness was just right in his hand, cut off the bamboo branches, left bamboo knots at one end, cut them into a half-foot long (about 16 cm) bamboo tube, made a dozen, pulled them back to the courtyard, and then spread them out in the sun to dry.

Then, he took out about one or two gunpowder powders, put them in a large bowl, poured in some alcohol, stirred well, and mixed them into gunpowder liquid for later use. Then find a thin rope about a zhang long, put it in the gunpowder liquid to soak and knead it thoroughly, take it out after a while, put the rope in a cool place without rain to dry, and after drying, it becomes a lead for igniting gunpowder, and put it away for later use.

A few days later, when the bamboo tubes were dried, Wu Zhi trimmed and polished them one by one, so that they were slippery and not prickly. Then take out two gunpowder canisters, first take out the powdered gunpowder and slowly fill it, fill one layer and press one layer lightly to make it tighter, insert a lead wire about four inches long when filling to four-fifths of the position, in order to keep it longer for safety, and then continue to fill gunpowder, compact, leave a space more than three fingers wide when it is about the same, plug it with waste paper, press it, put in a piece of perforated log to expose the lead, and then coat it with a thick layer of bladder glue seal, so that a simple bamboo "grenade" is ready! Then he took out the granular gunpowder and concocted it in the same way, and filled it with another bamboo "grenade".

Wu Zhi looked at the two bamboo "grenades" in his hands and was full of emotion. Xiao'e supported her little head on the side, and watched him operate in a daze, until she saw the finished product in his hand, and then asked weakly, "Brother Dalang, what is this?" ”

"Grenades!" Wu Zhi raised the bamboo tube in his hand and said proudly.

"A grenade?" Xiao'e was even more confused, pestering him and asking non-stop.

Wu Zhi couldn't explain it, so he had to take her and go out. He still has to test the explosion, and it is not clear how effective it will be, so it is difficult to say anything.

Wu Zhi and Xiao'e came to the back mountain, found a secluded and uninhabited place, beckoned Xiao'e to hide behind a big rock, he walked forward to a small tree a little farther away, first put a bamboo grenade filled with powdered gunpowder next to the root of the tree, took out the fire fold to light the lead, and hurriedly ran behind the big stone to hide in the sound of burning.

"Ahh Xiao'e was so frightened that she went straight into his arms, her face turned pale, and he hurriedly hugged her and comforted her a little.

After waiting for a while, Wu Zhi took Xiao'e's hand and walked out. I saw a mess in front of me, the smoke had not yet dissipated, the small tree did not fall, but a layer of bark was taken off from the root, the branches were broken, and a shallow small soil pit at the root of the tree was impressive, and white smoke was still emitting in the pit, and the grass two meters away was crooked. Xiao'e hugged his arm tightly, and was stunned and shocked. Wu Zhi looked at it, and judging from the scene, he felt that the explosion effect was still good.

Then, Wu Zhi put another bamboo grenade filled with granular gunpowder under another small tree, took out the fire fold and lit the fuse, and then quickly returned to Xiao'e to hide behind the big rock, and in an instant, there was a loud noise, earth-shattering, deafening, the sound was more violent than just now, and the earth and rocks flew.

After a while, Wu Zhi pulled the frightened Xiao'e back to the explosion site, and found that the explosion scene was even more messy. The smoke was filled, the small tree was blown off from the roots, and only the bark was attached to the ground slantedly, and there was a small soil pit under the tree, and the grass four or five meters away was blown to the ground, and the stumps and broken leaves were everywhere. This explosion is even more amazing than the explosion effect just now! The effect is also better!

If this bamboo grenade made of granular gunpowder explodes in a dense crowd, if you can add something dirty to the gunpowder, it is estimated that it can kill and injure the enemy at least five meters away, although it can't blow up a large piece of it as soon as it explodes, but the effect of such a blow is very amazing, especially for the psychology of breaking the enemy's defense, such a intimidation effect should be very effective, it can instantly capture people's hearts and destroy people's confidence, even if no matter how well-trained the team, in the face of such an amazing explosion, Its formation will also collapse in an instant, and it will no longer exist.

It can be seen that the explosive power of granular gunpowder is several times greater than that of powdered gunpowder!

Wu Zhi immediately decided to granulate all the new gunpowder.

The bamboo grenade has finally been developed, although there is still a certain gap with Wu Zhi's expectations, but at least it is also a good self-defense weapon, and it can be worn on his body to guard against the enemy, which makes him have more confidence in the future.

The explosion of these two bamboo grenades startled the nearby villagers to run out of their homes one after another, and asked what happened in shock, Wu Zhi could only explain one by one with a wry smile, and the villagers' doubts gradually disappeared.

Back home, Wu Zhi could only explain to Wu Xiu and Feng Niang again to dispel their doubts and panic.

The test explosion was indeed a bit big, indicating that the explosion effect of the grenade made of this new gunpowder was still very terrifying.

Next, Wu Zhi first sifted all the remaining powdered new gunpowder into granular new gunpowder, and after drying, he drew a gourd and filled it into the bamboo tube, but when filling, he used a flat-headed wooden stick to gently compact, which would press more tightly and the effect would be better, and at the same time make the lead slightly shorter, so that when it was thrown, it would explode faster, and not give the enemy a chance to react and dodge.

After loading, looking at the ten bamboo grenades placed in front of him, Wu Zhi was overjoyed and relieved. Xiao'e was on the side, and her eyes lit up, she could be regarded as having learned the amazing power of this bamboo grenade.

After making the grenade, Takeshi began to think about how to carry it conveniently. According to the way soldiers marched and fought in later generations, he could tie a leather belt or a wide cloth belt to his body, sew some hanging bags on the leather belt or wide cloth belt, and then insert the grenade in the hanging bag so that he could carry it. When using, you can usually plug in three or four, and the rest can be packed in a box for later use.

As soon as he said it, he informed Feng Niang of his design plan and asked her to help make this belt. Feng Niang was very strange about his thoughts, but she couldn't twist his begging, so she had to find some wide strips of cloth, there was no belt at home, and sewed a belt according to his idea, and at the same time sewed six hanging bags at equal distances on the belt, two on the left and right, two on the back, and the back of the hanging bag can be kept when not in use. Feng Niang looked at the strange-shaped belt in front of her, her expression was very rich, and she shook her head with a wry smile.

Wu Zhi ignored Feng Niang's strange gaze, took the belt, loosened the robe, tied the belt around his waist, and then inserted bamboo grenades in turn. Feng Niang is ingenious, the belt is made well, the hanging bag is sewn to the right size, just right to hold the bamboo tube, it will not fall out easily, and after inserting the bamboo tube, she doesn't feel much discomfort, she moves freely, and she can't see it after putting on the shirt. The lead is afraid of getting wet, so you can usually wrap a bamboo grenade in a piece of paper, and as for the fire fold, you can take it with you, everything is there, perfect!

Succeed with flying colors!

Wu Zhi was overjoyed, this was the weapon he wanted most for self-defense at the moment, and as for whether he could make a better weapon in the future, he would talk about it later.

After storing the bamboo grenade and putting his mind at ease, Wu Zhi began to study normally, meditate, practice boxing, kicking and bowing, and also had an additional training subject: practicing how to use a dagger.

Wu Zhi had never practiced knives, guns and clubs before, and the dagger couldn't be played with in his hand, and his movements were jerky and stiff. After research, he found a clue from the law of boxing, and spread it out along the boxing path, and found a routine for him to apply the dagger.

With the sharp weapons and measures for self-defense, Wu Zhi has a little more confidence and confidence in the future.
