However, Zhu Xiaobao's experiment this time was not successful, he had seen all the things in the past, even the bow and crossbow had been personally experienced in Zhao Meng's camp. But this time, I had to figure it out on my own. Because for things like mines and bombs, I have only seen them in film and television dramas, but I have never seen the real thing. At most, I have a little impression of firecrackers.

For Zhu Xiaobao's new experiment, Wu Yue and Tong Wuxin both showed great interest. The two of them are now obsessed with the inventions of Zhu Xiaobao! I feel that the greatest pleasure in this cave paradise is to be able to see some surprising things from time to time, and many of them are very useful.

So this time was no exception, Wu Yue and Tong Wuxin followed Zhu Xiaobao closely, wanting to find out. Wu Yue even resorted to a beauty trick, and very implicitly let Zhu Xiaobao take advantage of it. In fact, the two of them had already discovered Zhu Xiaobao's evil deeds---- peeked at the female soldiers taking a bath, and they also knew what Zhu Xiaobao wanted to see the most, because he kept looking around, searching, and finally slipped away a little depressed! It's just that neither of them debunked him, and this age is the most curious time!

"Alas! I just wanted to make a mine, a bomb or something, and that hole was always a hidden danger. And if you need it someday, I can help you too! But now my experiment is a failure! Zhu Xiaobao was not defensive against these two people at all, and said what he thought.

"Landmines? Bomb? What's that? Isn't it like a catapult that throws a big fireball that can burn? "It's kind of a quick reaction of Copper Wuxin, because she's seen this kind of scene, and when that kind of catapult is against a large army, the lethality is still very great. It's just too bulky, and it takes a long time to throw it once.

"Hmmm! It's pretty much the same, but it's much lighter, and it can come in many forms! …… It's still unclear ......," Zhu Xiaobao said after thinking about it.

"Then show us!" Wu Yue said very excitedly.

"Touch it! The kind that goes deep! I need to find a feeling, I'm a little unsure of the shape of the mine! Zhu Xiaobao said shamelessly, and he seemed quite reasonable.

"Get out! Little bastard, you want to take advantage again, don't think we don't know about you peeking at the female soldiers taking a shower! Wu Yue suddenly scolded angrily, after all, Tong's heart is next to her, she feels very embarrassed!

"Alas! I'm just looking for a feeling! Zhu Xiaobao sighed, Wu Yue is getting more and more difficult to fool now, how simple it was at the beginning!

"Humph! Looks like you're forcing us to do it, right? Wu Yue and Tong Wuxin were left and right, and they immediately picked up Zhu Xiaobao, and they didn't even touch the ground with their feet.

"Okay, okay, I'll admit defeat, I can't take you there!" The little BMW shouted like pigs.

Arrived at a very hidden place, this place is the most remote place in the whole cave heavenly blessed land, and there is a female guard on duty at the intersection, today it is Lu Fang, and the three of them are in exchange.

"How come I don't know about this house? You never told me? Wu Yue asked in surprise, the key is that Ying Xiuxiu and Lu Tong and Lu Fang did not report to her, which made Wu Yue very dissatisfied, as the closest person to Zhu Xiaobao, he didn't know this place.

"I designed it from the beginning, and a lot of very important experiments and equipment can't be known to others, except for the two of you, of course!" Zhu Xiaobao walked in front and said without looking back, seeing Lu Fang, he touched it very skillfully, although the movements were very hidden, but they were still clearly seen by Wu Yue. Wu Yue couldn't help but glared at Lu Fang fiercely, and almost cried when Lu Fang was wronged!

When I entered this large room, I found that it was divided into several private rooms, but there was nothing particularly new. There was only one room, and the table was filled with various jars and bowls, as well as many strangely shaped containers. Basically, they are fired, and some are made of wood.

Ying Xiuxiu was sitting there, holding the cotton thread in her hand and entangled with some core threads wrapped in black powder, watching Ying Xiuxiu do it very seriously, and she was already very proficient, it seemed that Zhu Xiaobao had a little time to make these things!

On the other side, Lu Tong was filling a clay pot with black powder, and she was not surprised to see Zhu Xiaobao, but when she saw Wu Yue and Tong Wuxin, she smiled a little restrainedly, and then said to Zhu Xiaobao: "Xiaobao, this tube is filled with the No. 3 formula!" It's already filled! ”

"Hmmm! Got it. You put it on the sample rack first, and then get me the smallest jar.

After waiting for a while, Zhu Xiaobao led everyone outside and said to Wu Yue and Tong Wuxin: "Look at it, this is the smallest jar, open your eyes!" ”

Wu Yue and Tong Wuxin glanced at each other, and they didn't understand what such a small tube could do, because this jar was too small, as big as a fist! There is also a small hole on it, which has been filled and stuffed with a cotton thread, which is the thing that Ying Xiuxiu processed just now.

This exposed cotton thread is half a foot long, Zhu Xiaobao touched his body, and then asked Tong Wuxin: "Is there a fire fold?" ”

"Yes!" There are a lot of these bits and pieces that Tong Wuxin carried with him, and he took out several things at once, all of which can cause fire.

"So much? What is it? Zhu Xiaobao saw it, and was stunned for a moment, but he didn't expect that there were all kinds of fire-causing things in this era, he pointed to a thin stone chip and asked.

"It's a flint stone, it's the fastest! Look at ......" Tong Wuxin couldn't help but explain a little proudly, and then took out a piece of wood, which could be seen to be processed, and the front part of the wood chip was stained with a lot of gray-white things. Tong Wuxin pressed the wood chips the thin stone chips, and then stroked along the stone chips, and the wood chips shined little by little, and then burned.

This reminds Zhu Xiaobao of matches, but this kind of processed wood chips ignite very slowly, not as quickly as matches, because of the lack of potassium chlorate. But this has already surprised Zhu Xiaobao, the so-called flint is also brushed with a layer of substances containing red phosphorus, whether it is phosphate rock, Zhu Xiaobao is not sure.

"Where did you buy this? Can I buy it in bulk? Zhu Xiaobao asked with great interest.

"Nope! This is from the Western Turks, it is difficult to buy, and it is expensive! If you want it, I'll leave it to you! Tong Wuxin said very generously.

"No, I just want to know where it's made, it's useless to have two pieces in one!" Zhu Xiaobao shook his head a little disappointed and said.

"That's it! What now, the chips are almost burned! Wu Yue asked a little impatiently on the side.

"Oh! Yes, yes, come on, light this! Zhu Xiaobao pointed to a piece of cotton thread inserted in the small clay pot and said, in fact, that is the fuse.

Tong Wuxin looked at Zhu Xiaobao, then took the piece of wood in his hand and lit the fuse. Unexpectedly, Zhu Xiaobao pulled Tong Wuxin and Wu Yue and ran, and Ying Xiuxiu and Lu Tong also ran quickly.

Running out more than ten meters, Zhu Xiaobao stopped, turned around, and saw that the fuse had burned to the filling hole of the small clay pot, and then quickly burned into it......

"Bang!"

With a loud sound, the small clay pot exploded, a dazzling fire burst out, and at the same time, many broken pottery shards also splashed everywhere, and a small pit appeared in the place where the small clay pot was placed just now, and a place of one or two meters around it was a piece of black ash. The farthest broken pottery shard actually splashed at Wu Yue's feet, and Wu Yue hurriedly took a step back.

"What is this? How can it burst open? And it's so powerful? Tong Wuxin asked in amazement, she had seen the burning boulder launched by the catapult, which was a huge stone pre-filled with sulfur, tung oil and other flammable materials, but it had to be ignited before it was projected, and the effect was indeed very shocking. It can cause a large area of burning, and it can kill and injure many people in the place it hits, but it is definitely not as light and convenient as this small clay pot.

"The black powder you saw just now is called black/gunpowder, and what Lu Tong filled into the small jar is black/gunpowder. A jar filled with black/gunpowder is called a bomb. But it's still not powerful enough! Zhu Xiaobao shook his head and said, don't look at the scene of the explosion, it's scary, but the lethality is very small.

"Then make a big one!" Wu Yue immediately thought of making a tuba!

"Hmmm! I'll try it tomorrow! Add some more iron spikes to increase the lethality. It seems that Formula 3 is the most powerful! Zhu Xiaobao was still comparing the results of these experiments and muttered to himself.

"Little treasure! What do you do with this kind of thing. Do you want to give it to the nineteenth princess? After being surprised, Tong Wuxin asked a little worriedly.

"No, it's too dangerous and it's not mature. I just want to increase my Cave Blessed Land's defenses, and I don't want the princess to know about it for the time being. and you shall not speak to anyone! Princesses included! Zhu Xiaobao shook his head and said, then looked at Wu Yue, to say that everyone else would listen to him. But whether Wu Yue will report to the princess, he is not sure, because the relationship between Wu Yue and the nineteenth princess is too close!

"I ...... I know, if you don't let me say it, I won't say it! Wu Yue said a little tangled, but in the end she still stood on Zhu Xiaobao's side.

"It's not that I can't say it, but this kind of thing is very powerful, once it is known, whether it is King Ming or the Seventh Princess, they will frantically find the source, and it is easy to find out what I have here, and then it will be a big disaster!" Zhu Xiaobao said solemnly.

"Then why are you going to make such a horrible thing!" Tong Wuxin also nodded, which she had just thought of.

"I'm feeling a lot of pressure! So many people are following me now, and I have a responsibility to ensure your safety, and I have a responsibility to ensure the safety of the Cave Heaven and Earth, so I want to make the defense here impeccable! I want you all to know that no matter what the circumstances, it's safest with me! Zhu Xiaobao waved his hand very hard, at this time it didn't look like the scoundrel little fat man, but it was a bit of a hegemon......
