Tang Xue'er was also looking at Chen Changfeng at this moment.

She believes that Chen Changfeng has a way, after all, Chen Changfeng has always surprised herself and has never disappointed her.

It's just that Tang Xue'er doesn't know how Chen Changfeng is going to solve the problem of the Tang Mansion.

And the white powder found on the walls of these toilets, what is it?

Tang Lin looked at Chen Changfeng and didn't say a word.

There was a look of doubt in his eyes.

"Take two basins, one large and one small, and fill them with water, and then put this saltpeter into a large basin, and put the small basin in the large basin." Chen Changfeng commanded.

Tang Mingren frowned, he understood this method very clearly.

Even small children can do it.

But what does this have to do with him solving the problems of the Tang Mansion?

"Prince, what's the use of doing this?" Tang Xue'er asked in a whisper beside Chen Changfeng.

"You'll find out later." Chen Changfeng smiled mysteriously.

Tang Xue'er looked at Chen Changfeng suspiciously.

Tang Lin didn't go to get the pot this time, and asked the servant standing in the distance to get it done according to Chen Changfeng's words.

The servants filled the basin with water and poured saltpeter powder into the basin.

And he put a small basin full of water in a large basin.

"Master, according to the prince's request, it has been done." The servant looked at Tang Mingren and glanced at Chen Changfeng next to him.

I wondered what this prince wanted to do.

Isn't this a child's play?

Tang Mingren waved his hand and motioned for the servant to step aside.

"Prince, what's next?" Tang Mingren looked at Chen Changfeng, waiting for his next move.

"What's next?" Chen Changfeng looked around: "It's time to eat next." ”

"Eat?" Tang Lin was stunned at that time.

What kind of solution is this?

How can this solve the dilemma faced by the Tang government?

Isn't that taking them for fools?

"Dad, you see, the prince is clearly making fun of our Tang Mansion, how can this be true!" Tang Lin was furious.

This is a useless thing, Chen Changfeng still has the face to say to eat?

Is it tolerable or unbearable!

Tang Lin was so angry that he was going to shoot directly at Chen Changfeng.

Since seeing Chen Changfeng today, Tang Lin has been impatient with Chen Changfeng.

At this moment, the anger has reached its extreme.

Tang Mingren's face also became gloomy.

He originally thought that Chen Changfeng was so confident before, and he really had a way to solve the problem of his Tang Mansion.

That's why he chose to let him give it a try, and even promised that if Chen Changfeng could solve the dilemma of his Tang Mansion, he could promise Chen Changfeng to serve as the servant of the ministry.

But now......

Chen Changfeng is completely making fun of his father and son.

"Prince, this is what you call ......"

"Why is this still smoking?" As soon as Tang Mingren wanted to question Chen Changfeng, he heard the servant's exclamation.

Tang Mingren looked at the two basins, and saw that the basin that had just returned to the original little movement actually began to smoke.

Bursts of white smoke rose up, Tang Lin stood beside him, and the white smoke quickly covered his legs.

Tang Lin's face changed slightly, and he subconsciously stepped back.

He felt that the temperature of his legs had suddenly dropped a lot.

"What is this?" Tang Mingren was shocked with a hint of panic.

He hadn't seen anything like it.

And people are both curious and afraid of the unknown.

"Haven't you ever seen water condensed into ice?" Chen Changfeng said lightly.

"Condensation into ice?" Tang Mingren's face changed suddenly.

He had only seen such a miracle in the mythological novels written by his predecessors, but Chen Changfeng just said, this is condensing water into ice?

Tang Mingren didn't believe it.

After a breath of silence, Tang Mingren slowly walked to the side of the wooden basin.

A faint chill came to his face, and Tang Mingren stretched out his hand to touch the water in the small basin.

But all he could do was touch a cold stone.

Tang Mingren reacted instantly, and what he touched in his hand was an ice cube.

Their Tang Mansion needs to transport the ice stored in the Tang Mansion Ice Cave from Zhao State every winter.

But just now, the water in this basin was obviously still from the well.

Chen Changfeng didn't even touch it, and the clear water turned into ice?

It's a miracle!

It's those white powders, what did the prince say that thing was called...... That's right, it's called saltpeter powder.

It must have been that thing that made the water freeze.

Condensing water into ice, it's so simple.

If the Tang Mansion can make ice from saltpeter powder on a large scale, then do you still need to buy ice cubes from Zhao State?

Will he still be threatened by the three princes with a border army?

No!

None of them!

Tang Mingren's right hand squeezed the ice cube in his hand, and his face was full of excitement.

"Dad, what's wrong with you?" Tang Lin saw that Tang Mingren didn't move, and thought what was wrong with him.

Tang Mingren got up slowly, tightly squeezed the small piece of ice that he pulled out in his hand, and turned his head to look at Chen Changfeng: "The prince is really a genius in the world, and the old man is really blind." ”

"Tang Lin, go and let people prepare wine and good food, I want to pay tribute to His Royal Highness the Prince."

Tang Lin was stunned, and when he saw the ice cube in his father's hand, his pupils instantly contracted.

Water turned to ice?

How did he do it?

Am I having a problem with my eyes?

Tang Lin thought in his heart, stunned in place.

"Don't go yet!" Tang Mingren shouted.

"Huh? I'll go! Tang Lin came back to his senses and left with a deep shock.

Tang Xue'er looked at the basin of water where the white smoke had slowly dispersed.

No, it should be said that it is an ice basin for now.

Because whether it is a small basin at the top or a large basin at the bottom, the water in the basin is frozen.

But just a quarter of an hour ago, there was still water in the basin.

"Prince, how did you do that?" Tang Xue'er looked at Chen Changfeng with excitement and stunned.

The servant next to him also wiped his eyes fiercely, looking at the ice cubes in the basin in disbelief.

Tang Mingren's eyes were firmly fixed on Chen Changfeng.

Although he guessed that it was the white saltpeter powder that was the work of the ice cube.

But that's just speculation.

He wondered if the real reason was what he had guessed.

"The white saltpeter powder, when it touches the water, absorbs heat, the temperature of the water decreases, and then it freezes." Chen Changfeng said with a smile.

Really!

A hint of shock flashed in Tang Mingren's eyes.

Although he guessed it, it wasn't until he heard Chen Changfeng's explanation at this moment that he was completely sure of the reason for the condensation of ice.

Tang Mingren looked at Chen Changfeng again.

Seeing that his eyes are like morning stars, his demeanor is graceful, his appearance is dignified, and he is a rare beautiful man in the world.

The more I look at Chen Changfeng, the more pleasing it becomes.

"Xue'er, you have a prince, and your father won't worry about it at all in the future." Tang Mingren said with a smile.

Tang Xue'er had a happy smile on her face.

Chen Changfeng can get praise from his father, which makes Tang Xueer happier more than anything else.

"Your Highness, you are amazing." Tang Xue'er looked at Chen Changfeng and said softly.

Chen Changfeng blew Tang Xue'er's nose, Tang Xue'er was ashamed, and ran out with her head down.

Tang Mingren looked at Chen Changfeng with a smile, and Chen Changfeng looked back at Tang Mingren: "Old Tang, can you still count the previous promise?" ”

The purpose of Chen Changfeng's coming today is to ask Tang Mingren to come out and take over the post of servant of the ministry, so as to help him grow his power in the court.

Tang Mingren looked at Chen Changfeng.

Before this, even if Chen Changfeng broke the sky, he, Tang Mingren, would not agree to take over the position of the servant of the ministry.

But now, Tang Mingren is full of confidence in Chen Changfeng.

I am also very curious, if Chen Changfeng keeps going down, how far can he go!

"Of course, it is an honor for the old man to be able to help His Royal Highness the Prince, and I hope His Royal Highness the Crown Prince will not dislike the old man's age." Tang Mingren got up and deeply bowed hands with Chen Changfeng.
