Originally, Leng Feng planned to prepare a college-wide welcome ceremony for this old guy, but was rejected by Hillary very insistently.

After all, he had come to see the new building materials and security doors, and he had to know that this was the lifeblood of his bank's security, so he couldn't be careless.

As for the rest, this old man really doesn't bother to bother with it now.

Seeing that this old man who was so happy was now so low-key, Leng Feng also knew that he was really in a hurry, so he immediately asked Liya and other teachers and staff to go to their respective jobs, and took Hillary to a courtyard located in the hinterland of the school.

In the middle of the courtyard, a high wall was now standing, and around Gao Qiang, there was a group of people busy.

The two people at the head are the little guy Gu Feng, and now he has joined the laboratory of the comprehensive college, leading a group of students to carry out related scientific and technological research work.

As for not far from the high wall, there is an old man in a robe standing, who else can there be if it is not Russell?

Now this old man has obviously completely integrated into the ordinary life of the academy, so that his mood has become more tranquil, except for Leng Feng, the master who knows his details deeply, the rest of the people don't even know that he used to be a terrifying necromantic holy magister.

Perhaps out of his reserve as a magician, even when he found out that Hillary was coming, the old man did not come to salute, but nodded his head from afar.

"Leng Feng, I didn't expect that there was such a character hidden in your academy, at least he was also at the level of a Holy Demon Master, right?"

After taking a deep look at Russell in the distance, Hillary couldn't help but ask in a surprised tone.

Although it was not the first time Hillary Clinton had come to the college, it was the first time she had met Russell because she had always kept a low profile.

"I can't tell you about this!"

Leng Feng shook his head slightly and said.

"It's just because Mr. Russell applied for the job when the college just recruited students, and he is admirable both in terms of personality and knowledge, so he has a lot of prestige in the college!"

"Oh!

Clinton nodded slightly, but instead of asking, she focused on the high wall on the side.

"This is what you call a concrete wall, right?"

Hillary couldn't help but ask.

"Yes, sir!"

Leng Feng hurriedly replied.

"In fact, this high wall is divided into three layers, the outermost layer is made of our latest red bricks, because it is filled with cement, so it is extremely strong, and the second layer is poured with concrete, and the inside is filled with steel bars, as for the third layer is stacked with red bricks again, its overall solidity can be said to be absolutely undoubted!"

"Yes, it's very thick!"

Under the introduction of the cold wind, after slowly stepping forward and touching the wall, Hillary couldn't help but nod and said.

It has to be said that after this kind of exterior wall made of red bricks is paved with a layer of cement, it is not only very strong, but also feels extremely delicate, far from being comparable to those rough bluestone walls.

And Hillary couldn't help but push it lightly with her hand, and after finding that the wall didn't move at all, she couldn't help but nod her head more and more.

In terms of Hillary's current strength, even if it only uses a few layers of power, it is extremely terrifying in comparison, and this wall can resist her own push, which makes Hillary first have a good feeling.

As Hillary Clinton stepped forward, the shareholders of the surrounding banks couldn't help but gather around and began to criticize the thick walls.

Although I know that this is a new thing that Leng Feng has once again made up, I am afraid that it will definitely not be simple, but since I have not seen it before, it is not easy for everyone to make a conclusion.

"Ladies and gentlemen, I know that you are still inconclusive about the safety of this new material, so why don't you ask this Russell teacher to experiment with it for everyone?"

Feelings: This magician was invited here because of this!

In a burst of enlightenment, everyone quickly retreated into the distance, and then looked at this side with blank eyes, it seemed that they were also very interested in this experiment.

At this time, Russell's old fellow stepped forward, only to see that he raised his arm very slowly, and he didn't see the slightest step of chanting magic, and a fierce flame was already burning in his hand.

"Go!"

With a brief snort from Russell, the flame immediately pounced like a flood beast, and began to gnaw at the outer walls of the wall fiercely.

"Good!"

Seeing Russell's methods, Hillary on the side couldn't help but shout hello when she saw the hunting heart!

After all, this Russell can cast magic in every move, not only without the help of spells, but also his movements are more skillful and free, as if flowing water, what is even more rare is that there is already a high-level magician between this shot, and the high level of his attainment can be imagined.

Although this Hillary is not a magician, after all, she has been on the battlefield for a long time, and this vision and insight are really not covered!

I didn't expect that this old guy seemed to be dormant during this time, and he was extremely low-key as a normal person, but he didn't expect that this strength would rise unconsciously, and it seemed that at least he had reached the high level of the Holy Demon Master, and he was almost starting to enter the threshold of the Law Saint, right?

Although the cold wind on the side remained silent, under the flickering eyes, he couldn't help muttering in his heart.

Under Russell's attack, the wall actually withstood the test, except that the outer wall was a little scorched because of the burning flames, and the whole body did not even tremble.

And this made the people around him can't help but let out a heartfelt exclamation.

If you change to an ordinary bluestone wall, you can still withstand this blow, but you will definitely be traumatized.

And this wall looks undamaged, no wonder the cold wind admires it so much!

However, what everyone still didn't expect was that just as the fire scorched the outer wall of the wall, suddenly a terrible hissing sound came from above the wall.

Because it was caught off guard, everyone couldn't help but be taken aback, and although Hillary was unmoved, she couldn't help frowning and asked the cold wind.

"Boy, what's going on?"

"Tell my lord, this is the self-protection device that comes into play with the wall, as long as it is hit by an external force and exceeds its predetermined value, then the pre-set alarm device will automatically activate, so as to give information to the surrounding guards to quickly rush to reinforcements!"

Leng Feng asked respectfully.

"Oh! I see!"

After nodding her head again, Hillary did not speak again, but observed more intently.

Russell in the field saw that his blow did not work, and immediately extinguished the flames with a wave of his hand.

In fact, this blow seemed to him to be just a pure test, in order to see how hard the wall really was.

Now that he had a faint score in his heart, he saw his lips squirm slightly, and he began to quickly recite magic spells.

Soon, a fireball almost the size of a wagon had formed above his head and swooped down diagonally like a flood beast.

It's still fire magic, but this time it's replaced with a powerful magic at the top of the high-level magician level - "Fire Meteor"!

Seeing that the fireball and the wall collided fiercely, a huge roar erupted, but in addition to a few violent tremors, the wall still stubbornly blocked Russell's way in the end.

"Good!"

Hillary, who was overjoyed, couldn't help but shout hello again.

But this time it wasn't for Russell, but for the thick walls!

Although Russell's performance is amazing, this wall can still stand under such an attack, and its strength is far greater than that of those bluestone materials.

Seeing that he had tried his tricks one after another but still had no effect, this Russell was obviously angry, and immediately saw him recite the magic spell again.

Compared with the original silent recitation, this time his tone was not only solemn but also slow, as if it took a lot of effort to spit out a single word.

And at this time, even Hillary on the side couldn't help but show a touch of seriousness on her face.

Obviously, this is the old guy who is going to make a big move!

Sure enough, after a long period of magical preparation, he suddenly saw Russell open his arm, and fierce magical elements immediately erupted around him.

This time, instead of using fire-based magic, he used earth-based magic!

With the shaking of the mountains under his feet, even the originally flat ground began to crack one after another in a hoarse moan.

As for the wall, it was finally unable to resist the powerful power of nature, and finally collapsed under the constant tremors, and a huge gap soon appeared in the thick wall.

It's still not enough!

Leng Feng couldn't help but sigh secretly in his heart!

According to his original idea, this wall must be able to withstand the full force of the Holy Demon Master, but now it has collapsed only to this point, so that Leng Feng is really not very satisfied.

However, he also knew that this was actually only a half-finished product, and he couldn't force it!
