"What the old man said is that spells are not allowed!" Chu Xun looked at Ning Ze and said word by word, "If Ning Zhonglang uses spells, he will fail!"

"Husband, Chu Gong is obviously deliberately embarrassed!" Liu Yuanxiang walked to Ning Ze's side, lowered his voice and whispered, "How to get ice in the hot summer?"

"This is not feasible at all!" Mi Yan also frowned sadly beside her.

Not to mention them, even Chu Meiren looked depressed, because she felt that it was impossible to get ice cubes this season, this was her father's means of refusing Ning Ze.

Ning Ze was full of confidence, and replied with a smile in the face of Chu Xun: "You can give it a try in the next place!" In addition to taking ice this summer, what are the other two major problems?"

Chu Xun stroked his beard and said, "If Ning Zhonglang can pass the first problem, the old man will naturally tell you!"

It means that if you can't even get over this, don't talk nonsense.

Taking ice in summer? Chu Xun himself didn't believe it, this was simply impossible.

"In that case, I'll get ice cubes for Duke Chu next!" Ning Ze said with a smile.

"Now?" Chu Xun frowned slightly, "Ning Zhonglang doesn't have to be in a hurry, he is about to order, and the old man does not limit the time." As long as it's still summer, it's counted!"

"It's okay!" Ning Ze replied, "This matter is easy, and it doesn't hinder it." ”

"Oh?" Chu Xun looked incredulous.

Liu Yuanxiang, Mi Yan, and Chu Meiren looked at each other, and they all felt puzzled. The heart said that Ning Ze didn't use spells, how could he get ice cubes in this hot summer?

Ning Ze turned around and beckoned to Liang Wu: "Little Wu, come here!"

Liang Wu immediately ran to Ning Ze: "What do you have to say, big brother?"

"Command two basins of water, one large and one small, to be filled and brought to me. Ning Ze ordered, "Also, go to the warehouse and get some saltpeter!"

"Saltpeter?" Liang Wu looked dazed.

"It is what was confiscated in the East Gate of the Tuo in the past, and there are some white spars in it, which were used to make gunpowder. Ning Ze said, "Hurry up and bring it." ”

"Wow!" Liang Wu immediately ran and set off.

Saltpeter?

Chu Xun, Liu Yuanxiang, Mi Yan, and Chu Meiren all looked puzzled, and they couldn't figure out what Ning Ze was going to do.

After a short time, two basins of water and a bag of saltpeter were sent to the hospital.

Chu Xun watched Ning Ze pour saltpeter into a relatively large basin of water, and then put a small basin of water into a large basin.

The chemical name of saltpeter is potassium nitrate, and when it is dissolved in water, it absorbs heat and lowers the temperature, so the water in the small basin freezes into ice.

Very simple knowledge of chemistry comes in handy at this time.

Next to them, Chu Xun, Liu Yuanxiang, Mi Yan, Chu Meiren, and Liang Wuwu couldn't understand what Ning Ze was doing, but they found that the water in the small basin gradually condensed into ice, and they were all dumbfounded, as if they had seen a ghost.

When the water in the small basin was completely transformed into ice cubes, Ning Ze reached out and took it out, handed it to Chu Xun and asked with a smile: "Duke Chu, I successfully took the ice cubes in Xia, can this problem be solved?"

Liu Yuanxiang, Mi Yan, and Chu Meiren had a strange light in their eyes, and they looked at Ning Ze with joy and admiration. After all, they are all young girls in their teens, and their hearts are full of pride when they find out that the man they like is so powerful.

Liang Wu was already surprised, in his opinion, Ning Ze was proficient in spells, what was this matter?

Facing the basin of ice cubes handed over by Ning Ze, Chu Xun stretched out his finger and touched it gently, and it was really cold.

He couldn't have imagined that anyone could actually fetch ice in the summer, and only with two basins of water and some strange stones.

It was precisely because he felt that no one in the world could do it that he would come up with this problem, how could Ning Ze easily take out the ice, and he couldn't understand what was going on.

Facing Ning Ze's question, he immediately said: "The old man said that you can't use spells! Ning Zhonglang must have used a spell that condenses water into ice!"

"Duke Chu has been wronged!" Ning Ze arched his hand and smiled, "Condensing water into ice is not an illegal technique, it is really a saltpeter skill. Saltpeter melt water absorbs heat, which is the principle of nature. If you don't believe it, Chu Gong can also try it himself!"

Ning Ze ordered to bring two more basins of water and give Chu Xun some saltpeter.

Chu Xun looked at the two basins of clear water in front of him, and then looked at the bag containing saltpeter in his hand, full of suspicion.

"There is a saltpeter mine in Huajun, which is located in Dongshan. Ning Ze said, "If Chu Gongruo is still suspicious, he can use my password to pick up himself in the mining area later, and then go home to do the test." However, saltpeter is very valuable, try to take some less. In the next to configure the most perfect gunpowder, the amount is very large. ”

Chu Xun didn't understand what gunpowder was, but Ning Ze asked him to use saltpeter to do experiments by himself, but he understood, thinking about how Ning Ze operated just now, he still poured saltpeter into the basin.

Sure enough, in front of everyone, the water in the small basin really condensed into ice, which was no different.

Ning Ze didn't make a move, which meant that it wasn't a spell.

But Chu Xun couldn't figure out why a few small stones could make the clear water condense into ice.

Where did he know chemistry? He was stunned by the strange phenomenon he had seen for the first time.

Liu Yuanxiang and the others were the same, they couldn't understand the principle of clear water condensing into ice, so they looked at Ning Ze one after another.

Facing everyone's eyes, Ning Ze said with a smile: "I just said that saltpeter melt water absorbs heat. You should be able to understand this explanation, the winter is extremely cold, so the water condenses into ice. Water is extremely hot and boiling, extremely cold and frozen, the common sense of the world. Saltpeter can absorb the heat in the water, causing the water temperature to plummet, reaching an extremely cold state like winter, so it condenses into ice!"

A group of ancients seemed to understand but did not understand.

"In short, contrary to boiling water, this stone is not the same as fire......"

"You say that fire is yang, and saltpeter is yin. The yang is extremely hot, and the yin is extremely cold?" Chu Xun asked curiously.

Ning Zexin said that if you want to explain it like this, let it be like this! So he nodded and smiled: "That's right! If Duke Chu doesn't believe it, he can do more tests after he goes back to prove that it is not an illegal technique." ”

"Hmm~" Chu Xun was really curious and wanted to figure out what was going on.

"Duke Chu, this problem has been solved, right?" Liu Yuanxiang hurriedly asked, "The husband has not used a spell, so it should be counted as a pass!"

"That's right!" Mi Yan immediately responded, "Husband has passed!"

Chu Meiren hurriedly looked at her father, although she was very interested in condensing water into ice, there were more important things.

Chu Xun faced their gaze, turned his head to look at Ning Ze, then looked at the ice cubes in the basin, and reluctantly replied after thinking for a moment: "Okay! Ning Zhonglang is really extraordinary, even if this question is passed!"

"Thank you Duke Chu!" Ning Ze smiled and arched his hand, "In that case, please ask the lord to ask the second question." ”

Chu Xun frowned, raised his head and thought about it, and said to Ning Ze for a while: "Since Ning Zhonglang can take ice in summer, he must also be able to find combustible water?

"Father!" Chu Meiren just heard the combustible water, and immediately thought of lamp oil, but was directly vetoed by his father, and said in his heart that in addition to oil, what else is there to burn water?

"I know!" Liu Yuanxiang's eyes lit up, and he whispered in Ning Ze's ear, "Husband, when the concubine was young, she accidentally knocked over the wine glass, causing the guest's liquor to fall into the charcoal basin and cause a fire, this liquor is combustible water!"

Ning Ze sweated on his forehead, and said in his heart, You are really powerful! Did you cause a serious fire?

It's just that before Ning Ze could speak, Chu Xun immediately said: "Ning Zhonglang, I forgot to say it! Spirits don't count." The old man wants water, and anything that has nothing to do with water cannot be regarded as combustible water!"

Hearing this, Liu Yuanxiang, who finally thought of spirits, was suddenly displeased.

Ning Ze nodded slightly, looked at Chu Xun and asked, "It must be water?"

"That's right, anything with oil and wine can't do it, it must be water!" Chu Xun said, "The old man wants combustible water!"

"Yes!" Ning Ze snapped his fingers, "Little Five!"

"In!" Ning Ze whispered a few words in his ear, and then said, "Go!"

Liang Wu immediately ran out.

Chu Xun saw that he was full of confidence, and said in his heart that he wouldn't do it, right? Although he thought about it temporarily, where could there be combustible water in the world except for oil and wine?

If Ning Ze didn't think of it, why was he full of confidence, what did he ask Liang Wu to do?

"Husband, do you know combustible water?" Liu Yuanxiang leaned over and asked.

Ning Ze smiled and said, "This bureau is too simple!"

Chu Xun frowned when he heard this: "Ning Zhonglang don't talk big, don't fool the old man with things that can't be touched!"

"I don't dare," Ning Ze replied, "Duke Chu wants combustible water, and he happens to know that a kind of water can be burned." As long as it's water, Duke Chu can recognize it, right?"

"Of course!"

"In that case, please go out with Duke Chu!" Ning Ze walked directly to the front.

Chu Xun looked suspicious and thought silently behind Ning Ze.

Liu Yuanxiang, Mi Yan, and Chu Meiren hurriedly followed.

Not long after, Ning Ze took Chu Xun to the blacksmith shop, and saw Liang Wu coming out of it, and said respectfully: "Big brother, it's okay!"

"Duke Chu, the combustible water is inside, it's better to ......" Ning Ze invited Chu Xun with a smile on his face.

In fact, the moment Chu Xun saw the blacksmith shop, he immediately realized that he had made a mistake and forgot such a simple thing!

What Ning Ze said must be molten iron, and he didn't seem to rule it out, saying that molten iron is not water, it seems to be a trick, this is not good. Therefore, he waved his hand depressedly: "Okay! The old man already knows what you are talking about, this question is the old man's own negligence, forgetting that there is molten iron...... Count you through!"

Liu Yuanxiang, Mi Yan, and Chu Meiren all smiled happily. In fact, when they arrived at the blacksmith shop, they all thought of this.

"In that case, could you please tell me what this third problem is?" Ning Ze looked at him with a smile.

Chu Xun sweated on his forehead, turned his head and found that his daughter was looking at Ning Ze with a stupid expression, and he was angry in his heart, he really didn't want to marry his daughter to Ning Ze. must come up with a difficult problem that can never be done, so that Ning Ze will retreat!

After pondering for a long time, he looked up at the sky and suddenly had a flash of inspiration, and said to Ning Ze: "These three problems are the boat in the air! Ning Zhonglang must find a boat for the old man that can travel in the air!"

Chu Meiren almost died of anger, her father obviously didn't want an old face, and he clearly didn't want to marry him. Just as he was about to protest, he heard Ning Ze reply: "You can try it in the air, but it will take a month!"

"A month?" Chu Xunxin said that you are joking, right? If you can really find a boat that can travel in the air, I will obey you! Not to mention marrying your daughter to you, this old bone can be called by you! He immediately said, "The gentleman is difficult to chase after the horse, if Ning Zhonglang finds the boat in the air within a month, even if he passes all the difficulties, the old man agrees to marry his daughter to you! If Ning Zhonglang can't do it, he can't talk about it again in the future, and he has to personally choose the best husband for the little girl and marry him off!"

"Father!" Chu Meiren turned her head to look at her father, unable to believe it.

"Don't worry, Duke Chu, this son-in-law is done!" the corners of Ning Ze's mouth curled slightly.

Hot air balloon to get to know it, is it difficult for me to stay?
