After all, those who can afford ice belong to wealthy families, and only those with strong backgrounds are not afraid of having such skills taken away by others.

What's more, making ice from saltpeter will eventually be discovered.

If there is no strong background, once exposed, the people running the business may suffer retaliation from these wealthy nobles.

Chai Lingwu not only has a profound background, but also has a naive character. No one wants to offend such a person easily.

After all, Chai Lingwu is a free-spirited demon king. Wouldn't it be uncomfortable to cause trouble for him?

With the definition in mind, Yang Fan thought about how to convince this guy to fall into the trap.

But Chai Lingwu was eager to say: "Master, now that midsummer has just arrived, the hot weather has lasted for nearly two months, and there is not much ice stored in the court. If you teach this magic to someone, you can make ice cream."

If you get the ice out and sell it on the market, you will definitely make a lot of money!"

Well?

Yang Fan was a little stunned!

I didn’t expect that this tough-minded Tiehanhan would have such a flexible mind. It’s really unbelievable!

However, it played into Yang Fan's hands and saved him a lot of effort.

Thinking of this, Yang Fan touched his nose and said: "Ahem, if you want to learn, it's okay. I'll give you the method later. However, this is not a magical method, it's just some chemical reactions!"

"Although this is not some magical skill, it can give you a way to make a living."

"You are going to marry Princess Shang soon. You can't keep asking for money from your family. Men, only when you have money in your pocket can you be confident."

"After you learn this craft, you can also add some sugar to the water and insert some wooden skewers. Under the unbearable heat, many people must want to taste the sweet and cold taste."

Feeling proud, Yang Fan got out the popsicles of later generations.

Chai Lingwu exclaimed excitedly, clapped his hands and said: "What the master taught me is that some time ago my brother said that I only know how to spend money and never thought about making money. Humph, I must make him look at me with admiration this time until I go back."

From now on, let me have someone study it carefully. When the time comes, I will make money and I will honor you as an old man."

Yang Fan was too lazy to pay attention to him.

Of the people he had made friends with, only Chai Lingwu didn't have a good career.

It doesn't matter whether it's money or not. You have to let the words of the people you are close to have weight, and then your goal will be achieved.

After talking about the business, Yang Fan picked up the iced wine, and the two started chatting while drinking.

Looking at the scorching sun outside the house and drinking ice-cold wine, Yang Fan suddenly felt that the heat had completely disappeared.

Neither of them spoke. After a while, less than half of the wine was consumed, and Yang Fan became a little drunk.

Not to mention, wine can really make you drunk.

Yang Fan felt very comfortable while humming a song while sipping the wine in the bowl.

Muffled sounds came from the distant workshops from time to time, and Yang Fan knew that this was the "Hangtian Lei" developed by the craftsmen who were testing it.

Listening to the rumbling sound, it seems to be very powerful, and it should be almost successful.

It's not that Yang Fan deliberately doesn't want to guide them step by step, but that some things can only become more valuable if they are tested by themselves.

Moreover, the ingredients of gunpowder, mononitrate, disulfide, and charcoal, have long been discovered, but the proportions are just different.

Of course, the more important thing is that Yang Fan is relatively lazy. Only by letting these people master each step clearly will they avoid being called every day for technical guidance in the future.

Hearing the deafening explosion, Chai Lingwu sobered up a little from his drunkenness.

He stretched his neck and looked out the window, but couldn't see anything. He could only turn to Yang Fan and asked: "Master, was this the sound of thunder just now? It was so terrifying, it was like the God of Thunder coming!"

"

Although I have never witnessed the power of Hongtianlei with my own eyes, due to rumors and rumors, Hongtianlei has become a myth.

Yang Fan said leisurely: "Ling Wu, in fact, thunder from the sky is not scary. What is scary is the human heart."

"Master is right!" Chai Lingwu thought for a while and nodded in agreement.

It's exactly what Yang Fan said.

If a just person holds this sharp weapon, it can intimidate the enemy and benefit the people.

If something like this fell into the wrong hands, it would be a disaster.

Therefore, thunder is not good or bad, it just depends on the person who uses it.

Looking at Chai Lingwu who was thoughtful, Yang Fan smiled slightly.

Although this guy looks naive, he is not stupid. No wonder this guy in the original history dared to rebel.

After drinking all the wine in the bowl, Yang Fan asked: "Lingwu, why did you want to come to firearms surveillance today? Is it just to give me something?"

Chai Lingwu did not hide anything, but said calmly: "Master also knows that His Majesty will come with all civil and military officials to inspect the production progress of the firearms supervisor. In order to ensure safety, this trip is in accordance with His Majesty's imperial order.

Check the surrounding area for any danger."

Yang Fan continued to ask: "Have you discovered anything?"

"No report, I don't know yet..."

Before Wu Ling finished speaking, a voice sounded outside the door.

"Lord Captain, the Qianniu Guards have completed their investigation and are here to report to you."

Seeing Yang Fan nodded, Chai Lingwu said loudly: "Come in!"

Soon, the door to the check-in room was gently pushed open, and a man with a red cherry crown on his head, wearing the standard imperial uniform and fast boots walked in.

First, he looked at Yang Fan with admiration.

This is the God of War rumored in the military!

Tibet will be decided in one battle. As long as they are soldiers, who doesn't admire them?

After the visitor saluted Yang Fan respectfully, he reported to Chai Lingwuhui: "Master Duwei, after a thorough investigation by the Qianniu Guards, no danger was found nearby. However, we discovered a bad phenomenon. It may be necessary for everyone to come."

Mr. Wei went to coordinate."

"Oh? What's wrong?" Wu Lingwu was a little surprised.

Speaking of which, they came to investigate first. It was just a routine inspection, but they didn't expect that there was really a problem.

Qian Niuwei quickly said: "It's not a big deal. According to the observation of my subordinates, there are many dirt trucks passing by the official road from Daming Palace, and a lot of dirt fell on the road during the transportation process."

"According to the observation of the Supervisor, it will rain in the next two days. Once it rains, the mud will be stuck on the road, and the road will definitely be muddy."

"My subordinates think it would be better if the captain came forward to say hello and ask the Daming Palace to suspend construction for a few days."

Chai Lingwu breathed out slowly: "I know, you go down first!"

In his opinion, this is simply a trivial matter.

However, when Yang Fan heard this, something felt vaguely wrong in his heart.

The construction of the Daming Palace has been completed long ago. Now it only needs small-scale repairs and no major construction work at all. Why does it need to transport so much soil?

What's more, there were no vehicles transporting soil some time ago!

Obviously, there is something famous here.

But Yang Fan did not express the doubts in his heart.
Chapter completed!
