But Zhu Xiaobao's experiment this time was not successful. He had seen all the things in the past, even the bow and crossbow, which he had personally experienced in Zhao Meng's camp. But this time he had to explore it by himself.

Because I have only seen things like landmines and bombs in movies and TV series, but never in real life. At most, I have only a little impression of firecrackers.

Wu Yue and Tong Wuxin both showed great interest in Zhu Xiaobao's new experiments. They are now obsessed with Zhu Xiaobao's inventions! They feel that the greatest pleasure in this paradise is to be able to

I saw some surprising things, 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 used a beauty trick to let Zhu Xiaobao take advantage in a very subtle way.

.In fact, the two of them had already discovered Zhu Xiaobao's evil deeds-peeping 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

He ran away a little frustrated! But neither of them exposed him. This is the most curious time at this age!

"Oh! I just want to make a mine, bomb or something like that. The hole is always a hidden danger. And if there is a need one day, I can help you! But now my experiment has failed!" Zhu Xiao said

Bao was not defensive at all against these two people and expressed his thoughts.

"Landmine? Bomb? What is that? Is it like a catapult, a big fireball that can be thrown out?" Tong Wuxin reacted quickly because she had seen such a scene before. That kind of catapult can deal with large-scale

When used as an army, the lethality is still very high. It is just too bulky, and it takes a long time to throw it once.

"Yeah! It's almost the same, but it's much lighter and can have many forms!... I still can't tell clearly yet..." Zhu Xiaobao thought for a while before saying.

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

"Touch it! It's very deep! I need to get a feel for it. I'm a little unsure about the shape of the mine!" Zhu Xiaobao said shamelessly, and seemed quite confident.

"Go away! You little bastard, you want to take advantage again. Don't think that we don't know about you peeking at the female soldiers taking a shower!" Wu Yue immediately yelled angrily. After all, Tong Wo Xin was right next to her, and she felt very embarrassed!

"Oh! I'm just looking for feelings!" Zhu Xiaobao sighed, Wu Yue is getting harder and harder to fool now, she was so innocent at first!

"Hmph! Looks like we are forced to take action?" Wu Yue and Tong Wuxin immediately picked up the little treasures without even touching the ground with their feet.

"Okay, okay, I'll admit defeat, why don't I take you there!" The little horses got up and yelled like killing pigs.

We arrived at a very secluded place. This place is the most remote place in the entire Cave Paradise, and there is a female guard on duty at the intersection. Today it is Lu Fang, and the three of them are here in exchange.

"Why don't I 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 have not reported to her, which makes Wu Yue very unhappy.

Satisfied, as the person closest to Zhu Xiaobao, he actually didn’t know about this place.

"I designed it from the beginning. Many very important experiments and equipment cannot be known to others, except you two, of course!" Zhu Xiaobao walked in front and said without looking back. When he saw Lu Fang, he was still very excited.

He touched it skillfully, and although the action was very subtle, Wu Yue could still see it clearly. Wu Yue couldn't help but glared at Lu Fang fiercely, which made Lu Fang almost cry!

After entering this very large room, I found that it was divided into several single rooms, but there was nothing particularly novel. There was only one room in which the table was filled with various jars and bowls, as well as many strange-shaped containers.

.Basically they are fired, and some are made of wood.

Ying Xiuxiu is sitting there, holding a cotton thread in her hand and twisting it with some core threads wrapped with black powder. She looks at Ying Xiuxiu doing it very seriously and very skillfully. It seems that Zhu Xiaobao is doing this.

Things are a little old!

On the other side, Lu Tong was filling a clay pot with black powder. 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 contains formula No. 3! It has been filled!"

"Yeah! 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, this is the smallest jar, let me open your eyes!"

Wu Yue and Tong Wuxin looked at each other, neither understanding what use such a small tube could do, because the jar was too small, as big as a fist! There was a small hole on it, and after filling it, it was stuffed

I took out a piece of cotton thread, which was the thing that Ying Xiuxiu processed just now.

The piece of exposed cotton thread was half a foot long. Zhu Xiaobao touched his body, and then asked Tong Wuxin: "Do you have any fire folds?"

"Yes!" Tong Wuxin carried a lot of these bits and pieces with him, and he took out several items at once, all of which could ignite fire.

"So many? What is this?" Zhu Xiaobao looked at it and was stunned. Unexpectedly, there were all kinds of fire starters in this era. He pointed to a thin stone piece and asked.

"This is a flint grinding stone, the fastest! Look..." Tong Wuxin couldn't help but explain with some pride, and then took out a piece of wood. It could be seen that it had been processed, and the front part of the wood piece was stained with a lot of grayish white.

Something. Tong Wuxin pressed the wood piece hard against the thin stone piece, and then scratched it along the stone piece. The wood piece shone little by little, and then burned.

This reminded Zhu Xiaobao of matches, but this processed wood chip ignited very slowly and was not as fast as a match because it lacked potassium chlorate. But this already surprised Zhu Xiaobao. The so-called ground wood chip ignited very slowly.

The flint is also coated with a layer of material containing red phosphorus. Zhu Xiaobao is still not sure whether it is phosphate rock or not.

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

"No! This is passed down from the Xijue tribe. It's hard to buy, and it's expensive! If you want it, I'll leave this to you!" Tong Wuxin said generously.

"No, I just want to know where it was produced. One or two pieces is useless!" Zhu Xiaobao shook his head in disappointment and said.

"Okay! What to do now? The wood chips are almost burned out!" Wu Yue asked impatiently from the side.

"Oh! Yes, yes, come on, light this!" Zhu Xiaobao said, pointing to a piece of cotton thread stuck on the small clay pot. In fact, that was the fuse.

Tong Wuxin looked at Zhu Xiaobao, then took the wood chip in his hand and lit the fuse. Unexpectedly, Zhu Xiaobao took Tong Wuxin and Wu Yue and ran away, followed by Ying Xiuxiu and Lu Tong.

After running for 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 it in...

"boom!"

With a loud sound, the small clay pot exploded, and a dazzling fire burst out. At the same time, many broken pottery fragments also flew everywhere. A small pit appeared where the small clay pot had been placed, and the surrounding areas

A place one or two meters away was filled with black ash. The farthest broken pottery fragment actually flew to Wu Yue's feet, and Wu Yue quickly took a step back.

"What is this? How could it explode? And it's so powerful?" Tong Wuxin asked in amazement. She had seen burning boulders launched by catapults. Those huge boulders were pre-filled with sulfur.

Tung oil and other flammable materials must be ignited before being thrown out. The effect is indeed very shocking. It can cause large areas of burning and can kill and injure many people where it is thrown, but it is definitely not as light and convenient as this small clay pot.

.

"The black powder you just saw is called gunpowder. What Lu Tong filled into the small jar is black gunpowder. The jar filled with black gunpowder is called a bomb. But the power is still not enough!" Zhu Xiaobao shook his head.

He shook his head and said, although the explosion scene is scary, the damage is very small.

"Then let's make it a big one!" Wu Yue immediately thought of making it a big one!

"Well! I'll try it tomorrow! Add some iron thorns to increase the lethality. It seems that the No. 3 formula is the most powerful!" Zhu Xiaobao murmured to himself while still comparing the results of these experiments.

"Xiaobao! What are you doing with this kind of thing? Do you want to give it to the Nineteenth Princess?" After Tong Wuxin was surprised, he asked a little worriedly.

"No, this kind of thing is too dangerous and immature. I just want to increase the defense of my Cave Heaven Paradise, and I don't want the princess to know about it for the time being. You are not allowed to tell anyone! Including the princess!" Zhu Xiaobao shook his head and said

, and then looked at Wu Yue, saying that everyone else would listen to him. But he was not sure whether Wu Yue would report to the princess, because the relationship between Wu Yue and the Nineteenth Princess was too close!

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

"It's not that I'm not allowed to talk about it, but this kind of thing is very powerful. Once people know about it, both Prince Ming and the Seventh Princess will search for the source frantically. It's easy to find it here, but then a disaster will be imminent.

!" Zhu Xiaobao said with a solemn expression.

"Then why do you want to do such a terrible thing!" Tong Wuxin also nodded, she had thought of this just now.

"I feel great pressure! So many people are following me now. I have the responsibility to ensure your safety and the safety of Cave Heaven Paradise, so I have to make the defense here impeccable! I want you all to know
