After finally succeeding in breaking down this wall, Russell couldn't help but secretly breathe a sigh of relief in his heart.

To say that he had never taken this building material to heart before, he never thought that its hardness could reach such a level, which made him impressed.

But fortunately, he did not lose face after all in front of everyone, which made Russell's pride as a holy demon master a little satisfied.

As for the others, they couldn't help but show a look of shock on their faces.

After all, this level of hardness has far surpassed their cognition, and it is much better than the bluestone materials that are now prevalent on the mainland.

You know, almost all of the people present were big businessmen and tycoons who controlled the lucrative industry, so everyone already saw the promise of this material.

Seeing everyone's performance like this, Leng Feng couldn't help but laugh secretly in his heart, but he still made an embarrassed expression and said.

"Everyone, in fact, the limit of this material can withstand the full force of the Holy Demon Master, but since it is still a semi-finished product, the result can only reach this level!"

Oh, my God!

It's surprising enough to be able to withstand a full blow from a Magister, but that's not the limit of this material, is that a joke?

There was already some disbelief in everyone's hearts, but fortunately, Babos among them was quite resilient, and he immediately asked urgently.

"So Mr. Cold Wind, I don't know how much this kind of wall costs?"

"Don't you know, Mr. Barbos, that such a question is very rude?"

Leng Feng frowned slightly and said.

This novel material and the strength is so high, it has far exceeded everyone's imagination, plus now only Leng Feng can do it, so the price is not with him?

Then the cost is naturally a trade secret!

How could Babos not know about the mystery of this? It was only because he was so eager that he made such a mistake.

Immediately, I saw the dead fat man smile slightly embarrassed, and before he could speak, Leng Feng continued.

"But since everyone is so familiar, I might as well tell you a reserve price, the selling price of this material is about one gold coin per cubic meter!"

To be honest, such a price is actually still within the range of acceptance by everyone, after all, the superior performance of this material is there!

It's just that even so, everyone can't help but fall into a deep thought.

After all, its high cost has far exceeded today's ordinary bluestone materials more than 100 times, although his performance is superior, but it is even more difficult to promote among the common people, the main reason is because it is too expensive.

For everyone's thoughts, how could the cold wind not be able to see it? He couldn't help but smile slightly and said, having been prepared for a long time.

"Everyone, in fact, this offer is actually only for the highest grade building materials, after all, this wall is specially tailored for the bank's vault, for the safety of its funds, so even if this material is expensive, it must be used, right?"

This is true, after all, as the bank's funds become more and more abundant, the problem of its capital security has also begun to become more and more apparent.

Although Marquis Hillary has been on strict guard around the vault, considering that some of the people who want to get their hands on the funds may be powerful bulls, everyone is still a little apprehensive.

Therefore, even if this material is expensive, everyone is afraid that they will pinch their noses and admit it, isn't this to spend money to buy a peace of mind?

And this kind of loss is actually quite cost-effective compared to the large amount of money caused by the fall of the vault.

Sneaking a glance at everyone, he couldn't help but show a look of deep approval when he found that everyone, including Hillary's old goods, was almost happy in his heart.

He knew that his first order for building materials would not have to be worried.

Although he thought so in his heart, Leng Feng's thoughts were still running rapidly, and he continued.

"If it is an ordinary civilian, of course, there is no need for this kind of strength, then the price does not need to be so high, only about one percent of the original is enough, and we absolutely guarantee its quality, according to my preliminary calculations, even if it is a civilian building, if you use my materials, it will almost maintain a three-hundred-four hundred years, which is also a very common thing!"

"Not only that, but our materials have many other benefits besides the hardness, which can be well protected from cold and heat, so that the people who live in it can definitely feel extremely comfortable!"

After hearing Leng Feng's words, these rich people, including Babos, couldn't help but be overjoyed again.

If it is really as Leng Feng said, then the market prospect of this new building material is absolutely undoubted.

Not only the performance is superior, but also the cost is similar to the original bluestone material, where to find this kind of good thing?

So much so that everyone's minds began to turn rapidly at this time, and they began to think about how to get a share of the benefits of this building material.

But obviously, the shock brought by the cold wind to everyone was far more than that, and he said again.

"By the way, today coincides with the day when our new campus is about to be completed, so since everyone is here, why don't you take a tour with me?"

"Mr. Leng Feng, are all the brand-new materials used in your new campus?"

Babos was the first to stand up and ask.

Damn, no wonder this kid can become the leader of today's aristocratic circles, this brain is really fast, right?

While secretly sneering in his heart, Leng Feng immediately replied with a smile.

"That's right! Although the materials specially developed for the vault still need some time to be perfected, if they are put into civilian use, they are already fully competent, so the establishment of the new campus this time is completely based on the use of this new material!"

"Okay! Take us there!"

Babos immediately couldn't help but say with some impatience.

"Okay, but before that, please hold back for a moment, because there's another product you haven't seen yet!"

Speaking of this, the cold wind pointed to the side, and everyone realized that there was a metal door on the wall!

"Ladies and gentlemen, this is the second product I show you, and that's the security door!"

"Mr. Cold Wind, is this the door that will be used in the bank vault in the future?"

Babos asked again duly enough.

"That's right!"

Leng Feng couldn't help but cast an appreciative look at this guy, nodded and said.

Originally, everyone was still a little dissatisfied with Leng Feng's unappetizing behavior, but now they had nothing to say, and they gathered around and looked carefully.

I saw that on the square metal door frame, there was a circular gate inlaid with various criss-crossing mechanisms on it, which made people look very powerful.

While everyone was still looking, the cold wind glanced at the ancient wind on the side.

The kid who had been silent all the time easily got the opportunity to perform in front of everyone, and immediately stepped forward to operate and demonstrate, while Leng Feng continued to explain.

"Compared with building materials, the process of this security door is very mature, so you can see it as a sample, but the security door used in the vault in the future will definitely be more secure and safe than this door!"

"It's not that I'm boasting, this security door can be said to be the most complex door today, because it not only requires three sets of keys to twist at the same time, but also needs to enter twelve sets of passwords to open, and in order to ensure security, the passwords of these twelve groups must be adjusted after a certain period of time, in order to ensure its absolute insurance!"

"In addition, the material of this gate is made of the latest alloy steel, so whether it is toughness or strength, it is no worse than the wall of the new material, and it is also equipped with an automatic alarm magic guide device, once it suffers a heavy blow, it will immediately call the police!"

"Of course, because of the confidentiality involved, the performance of this sample is much worse than that of the finished product, especially about the combination lock and related technology is not used, which is mainly for confidentiality, but even so, you can see the advantages of the future security door from it!"

Under Leng Feng's explanation, no matter how many people tried, they couldn't move the iron door at all, until the ancient wind stepped forward again and used the key to open it.

Seeing this, Hillary on the side couldn't help but breathe a sigh of relief.

With the new material and the double insurance of this security door, the safety of the bank's funds will undoubtedly make you feel at ease.

"Alright, Mr. Cold Wind, it's almost time to take us to your new campus, right?"

After looking at the security door, someone finally couldn't help but propose.

Although the effect of this security gate is very impressive, but now everyone's mind is still on the new campus.

You must know that many of the people present are also investors in the comprehensive college, so that under the itch, they can't help but ask for it with confidence.

"As everyone wishes!"

I saw that Leng Feng was very chic and said after a bow.
