Zhao Gao sent someone to call the Meng family brothers.

In a small room in Jingyao, there were three small piles of powder on the table, which were sulfur, saltpeter, and charcoal.

Ying Zheng and the others widened their eyes to look at this pile, and then at that pile, and circled around the table.

"It's nothing special, it's just three small piles of ordinary materials." Meng Yi was the youngest and said impatiently.

"Didn't the king say that it has to be mixed together to have an effect." Meng Tian shook Meng Yi with a cold eye and said.

Ying Zheng stood up straight and said softly: "Then let's start, Tian Yi will take the hand, and the others will stand farther away." ”

The general dirty work is tiring and dangerous, and the work is usually handed over to Tian Yi to do.

Several people retreated backwards, straight to the corner of the wall, and Meng Yi's hands were subconsciously crossed in front of his chest, making a defensive posture.

Li Si looked at the expressions of these people and couldn't help laughing.

Wearing gloves sewn with twine, Tian Yi carefully pushed the powder of sulfur and charcoal little by little towards the middle.

The two piles of powder got closer and closer, just at the moment when they were about to merge...

Meng Tian's wrist was suddenly grabbed hard, and he couldn't help but be startled.

When I looked down, it was Meng Yi's hand, and then I looked at Meng Yi, who had already turned his head and closed his eyes.

Meng Tian glanced at Meng Yi again, looking at this unproductive appearance.

Tian Yi had already mixed the two piles of powder together.

However, there was no reaction at all.

Tian Yi began to stir with both hands, so that the two piles of powder could be mixed evenly.

Meng Yi also opened his eyes, however, there were a few more beads of sweat on his forehead.

Meng Tian shook off Meng Yi's hand and complained: "You, this is the way you went to the Tomb of King Wu last time, and next time there is such a thing, I won't take you out." ”

"Don't, brother." Meng Yi said, "Aren't I also trying to create some tension? ”

Ying Zheng, Li Si and the others were all amused by the two brothers, only Tian Yi was meticulously mixing the two powders.

After a short time, the two powders have been completely mixed evenly, and there is still nothing out of phase.

Several people did not relax, because there was still a pile of charcoal that had not yet been mixed, and they were also staring intently.

Tian Yi began to push the small pile of charcoal towards the large pile of mixed powder.

Li Si felt that the atmosphere was really a little too tense, so he said: "You don't have to be so nervous, it's okay, these powders after mixing can't touch the fire, instead of burning after mixing." ”

"Hear me, this powder doesn't catch fire." Meng Tian pulled Meng Yi, who was half hiding behind him, "When you get to the battlefield in the future, how can you go into battle to kill the enemy." ”

"That's different." Meng Yi strengthened his courage and stood up from behind Meng Tian.

Several people watched the brothers arguing and couldn't help but want to laugh.

At this time, Tian Yi pushed the scraps of the pile of charcoal and had already touched the mixed scraps before.

Everyone stopped talking about the trouble, and stared straight into the eyes.

Tian Yi was also quite careful, and mixed the two piles of scraps very gently.

Nothing out of the ordinary happened.

Meng Yi breathed a long sigh of relief, and seemed to be much more relaxed.

Finally, the three powders were evenly mixed together, and several people were no longer afraid, and took a few steps forward to watch carefully, but they were also separated by some distance.

"Deputy head of the team." "I also bothered to pack the gunpowder into the bamboo knots in different quantities, and then put the fuses on each of them. ”

Tian Yi nodded, and then according to the way Li Si explained before, different amounts of gunpowder were packed into different bamboo joints, and Jing Fan made the lead on the side.

The two of them were very meticulous in their workmanship, and even their breathing was very slow, for fear that the exhaled breath would blow away the gunpowder.

Yingzheng and several people were also far away, I don't know if they were afraid of being injured, or they were afraid that they would blow away the gunpowder with the same exhalation.

In nearly half an hour, gunpowder was loaded into five bamboo knots and fuses were installed. There was still a bit of gunpowder left on the table, which was reserved for demonstration fire.

Jing Fan filled this small pile of gunpowder

entered a cloth bag, leaving no trace, probably because he was afraid that in case of a fire, he set this kiln on fire.

Lees led the crowd to the shooting range.

Zhao Gao had already made preparations, ordered people to move some stones and weeds in advance, as well as a lot of buckets filled with water, and also placed a few flying crossbows, and a lot of crossbow arrows wrapped with pine trees, and then ordered all the sergeants to withdraw from the shooting range, and ordered that no matter what noise they heard, they should not enter the shooting range without permission.

Lees ignited an arrow, then leaned over and ignited the small pile of gunpowder.

The gunpowder instantly sparked and burned. However, because the portion was too small and there was no combustible, it was extinguished in an instant.

Everyone didn't expect Li Si to ignite the gunpowder directly, and they couldn't help but be a little afraid.

"Sir, this ......" Ying Zheng was worried that there would be other conditions with gunpowder.

"Don't worry, the king, Weichen is just showing what normal gunpowder looks like when it burns."

Jing Fan stepped forward to take a look and said, "It seems that it is indeed more flammable than oil, but it is also consumed faster." ”

"Therefore, to put it in the bamboo is to use the explosive power of its combustion, not the role of combustion and lighting." Lees explained.

Ying Zheng and everyone nodded. The world's understanding of fire is, of course, only burning and lighting.

"Since there is a certain danger, don't get too close, you will have to rely on Meng Tian's archery technique for a while." Li Si pointed to the bamboo knot filled with gunpowder in the distance and said.

Although Meng Tian's archery technique is not a hundred steps through Yang, it is also the best archery among several people.

Meng Tian stepped forward and arched his hand, "What does Sir need me to do?" ”

"The five bamboo knots containing the gunpowder, which had been placed in different places, were all covered with stones or trees of different sizes." Li Si handed the crossbow arrow to Meng Tian and said, "General Meng only needs to shoot the respective leads with the flying crossbow, and that's it." ”

Meng Tian took the crossbow arrow, looked at the position of several bamboo joints, and said, "This is not difficult. ”

The first bamboo knuckle, placed ten paces away, was pressed with some small stones.

Meng Tian exhaled lightly, stabilized his mind, looked at the position of the lead, and pulled the trigger of the flying crossbow.

The fiery bolts flew out and pierced directly into the lead.

Ying Zheng and the others widened their eyes and saw that the lead was burning rapidly.

Meng Yi subconsciously took a step back, and half-blocked his eyes with his hand.

Syllable! ……

With a crisp sound, the bamboo burst open, scattering the stones above, and blasting a crater out of the ground below.

Ying Zheng's mouth opened wide and looked there in surprise.

Everyone was also taken aback, and Meng Yi also took two steps back.

Meng Tian remained silent, and ignited another arrow feather and put it on the flying crossbow.

The second knot was buried five steps away from the first, and the amount of gunpowder in it was a little more than the first.

Meng Tian calmed down, looked at the position of the lead, and shot the second arrow.

Sou......

The arrow hit the lead accurately, and the lead ignited.

Boom!! ……

There was another loud bang, and then the stones on the bamboo knots were shattered, and the pit on the ground was a little bigger than the first.

Meng Tian put down the flying crossbow in his hand, raised his hand to signal, and then led Tian Yi to the front of the two dirt pits.

The two men examined the scorched earth inside the pit and looked at the stones and fragments of bamboo.

Tian Yi also grabbed the scorched earth and sniffed the smell.

The two of them put everything they could collect into their cloth bags and then returned.

Ying Zheng led the crowd to inspect the scorched earth and the fragments of stone and bamboo.

"It seems that the fragments of this second bamboo are more finely broken, and the broken stones are even finer." Ying Zheng said.

"The distance from the collapse is also farther." Meng Tian added.

"The pit is also collapsing even bigger." Tian Yi also added, "Moreover, the smell of those scorched earth is also greater. ”

"Then, it also shows that the more gunpowder is loaded, the more powerful it becomes." Ying Zheng looked at Li Si and scored

Analysis.

Li Si smiled and said, "The king's analysis is good, but has the king ever thought that if the gunpowder is not a bamboo joint, but a larger utensil, it will contain more gunpowder?" ”

Hearing this, everyone gasped.

Li Si looked at the remaining bamboo knots and said, "Let's finish experimenting with them all, let's discuss them again." ”

"Okay." Ying Zheng stopped thinking, led everyone back to the original point, and raised his hand to signal Meng Tian to continue.

Meng Tian nodded, and ignited another crossbow arrow, aimed at the third bamboo joint, and shot the third arrow steadily.

As expected, the power of this third bamboo joint has increased a lot compared to the first two.

Another arrow was fired, and the power increased again. And this time, even Ying Zheng unconsciously took two steps back.

Except for Li Si, the shock in the hearts of several people was higher than that.

If it is a person, let alone a life, even the whole corpse will not be left.

There is still one last bamboo lud, but unlike the previous ones, this one is not pressed down by a stone, but is inserted under the root of a poplar tree with a bowl mouth.

And the distance between this tree and everyone has exceeded 100 steps.

Meng Tian ignited the arrow and shot a flying crossbow.

Probably because of the distance, the arrow hit the position slightly off.

Meng Tian lit another arrow, exhaled a long breath, steady, and then aimed and fired.

This time it is impartial and the lead is in the middle.

Rumble! ……

There was a loud explosion, and everyone only felt that the ground under their feet was trembling.

Look at the small tree again, although it was not lifted off, its roots were also broken, and it slowly fell to one side.

Several people were dumbfounded, and they didn't speak for a long time.

Li Si quietly walked down Meng Tian, took the crossbow, and hung it on the crossbow stand.

Meng Tian was missing something in his hand, and he was the first to come back to his senses: "This, it's too powerful, if you use this gunpowder to blow up the city gate, there is no city that can't be attacked." ”

"It's better to open a mine, and it's a lot less effort." Jing Fan said with a smile.

"If you throw it into a fish pond, you can make sure you blow up a lot of fish." Meng Yi smirked.

Ying Zheng and several people looked at Meng Yi with disdain.

This guy is not only timid, but also always wants to eat.

"Sir, you said that if you want it to be more powerful, you need to put more gunpowder into a larger vessel, right?" Ying Zheng asked.

"Yes, the more servings, the more powerful." Lees replied.

"What if you put more gunpowder into a larger iron pipe?" Ying Zheng asked again.

"Naturally, it's more powerful." "However, in that case, it will be very inconvenient to carry and increase its own danger, so Wechen suggests that it is enough to use bamboo to carry gunpowder." ”

"Okay." Ying Zheng nodded and said, "According to what Mr. said, only bamboo is used to load gunpowder, and it is only used for mining minerals. ”

"Then please give the king a name for the bamboo that is loaded with gunpowder." Lees said.

Ying Zheng pondered for a moment and said, "Since this bamboo will explode after being ignited, it will be called a firecracker." ”

"Yes, Your Majesty." Li Si arched his hand and said.

Ying Zheng looked at Jing Fan and said: "Now that there are firecrackers, it is not so difficult to open a mine, from today onwards, we will make all our efforts to mine minerals, and the widow will make 'my device' as soon as possible, as well as the colorful paint." ”

My Healing Game

"Wechen obeys the king's orders." Jing Fan arched his hand and said, "But Your Majesty, those colored paints have been imitated with the help of Master Li. It's just that Lord Li instructed that he couldn't say it until after the king's wedding. ”

"Really?" Ying Zheng looked at Li Si with some suspicion, "Didn't Mr. say that you need to find the black fire oil first?" ”

Li Si smiled and said: "Although the black fire oil is difficult to extract, it is not without stock in the world, and Weichen happened to buy some before he came to the Qin State. ”

Ying Zheng slapped his head.

Yes, it is to be imitated, not mass-produced, and it is enough to spend money to buy a little.
