Although the "Quartz Jixiong" "created" a large amount of sand to eliminate a large number of giant robots, it also left a huge sand dune in front of everyone.

"But it's much better than a robot!"

In the midst of a group of students, someone made a noise and then mobilized his personality and tried to cross the dunes.

However, seeing their movements, Qin Ren couldn't help but chuckle, but he seemed to remember something:

"It's not good, I almost forgot, this is for you to be assessed, I have to make it more difficult for you."

In the middle of the arena, "Quartz Jixiong" raised his hand, absorbed countless black-gray gravel from the ground, and sprayed it onto the sand dunes, and in the blink of an eye, the entire sand dune turned black-gray.

Then, in the mouth where the quicksand condensed, the grit trembled, mimicking the vocal cords to make a quartz second male voice:

"Let me warn you, these are flint sand."

And his voice is also transmitted to the audience through the broadcast camera.

"Flint Sand? What is that? ”

"I don't know......"

"Does it work?"

And in the crowd blocked by the quicksand, Eight Million Bai thought for a while, and then suddenly something sounded, and said to the Class A classmates beside him:

"Be careful! Flint is a variant of quartz, which can produce sparks when hit with iron tools, so it was also used as a fire tool by ancient people! ”

Eight million hundred eyes stared at the black-gray sand dunes: "You all try to be careful, the flowing flint sand is easy to produce high heat, and if it is hot, it will ......"

Everyone followed her gaze to the huge sand dunes full of quicksand, and one word came to their minds-

"Dust Explosion"

Not only them, but also the audience's little expertise in their minds has come together to create a variety of dangerous situations.

"What's the matter with that student!!"

"How can you do such a dangerous thing!"

"This is too vicious!"

With Qin Ren's perception, of course he could hear these words, but he just rolled his eyes.

If those giant robots attack someone, they can directly kill them, why don't you say that the giant robots are dangerous, but that the dust explosion is dangerous?

What's more, it is very simple to solve the situation.

Class B's Bone Puller can soften the ground with his personality, sink the sand, or wet the sand with water, anyway, there are many ways, and he can come up with a dozen or so ways to clear the dunes and avoid explosions.

In addition, flint sand is prone to high heat due to friction, but what about it......

The main characteristic of flint is that it is hard, and it can produce sharp fractures when broken.

Originally favored by primitive people in the Stone Age, most stone tools were made with flint strikes, which sparked when struck, but were difficult unless they were struck with metals such as iron.

That is, the early flint and steel.

Flint guns also use triggers to strike flint to ignite gunpowder.

But he didn't have a lot of flint out of the ground, and that large piece of flint sand just looked bluffing, and it couldn't burn people or reach the high temperature that could cause a dust explosion, unless someone rolled around on it hundreds of times with iron or other metal, it wouldn't be fine.

The palm of his hand was raised, and countless quicksand sprayed out from the hands of the "Quartz Cixiong", and after cutting off a medium-sized robot that was approaching, the Qin people continued to control him to move forward.

Listening to the discussions of the surrounding melon-eating masses and melon-eating heroes, several more sensible heroes couldn't help but shake their heads, and then talked about it:

"This teenager is quite skilled in the use of personality, and it seems that he has also done a lot of training on the limits of personality, making so much sand, and still not a little tired......"

"Indeed, by narrowing the jet port, sand is created at high speed, and a powerful destructive force is formed in an instant....."

"It's like a high-pressure waterjet, right? The power of a high-pressure waterjet with sand and a high-pressure waterjet without sand is completely different. ”

"His use of personality is enough to be a professional hero."

"But professional heroes aren't just about the use of personality, and a hero license isn't just about personality."

"I'm just comparing them."

"However, speaking of which, the ability to make quartz sand is a personality that may be solicited by Mr. Izir, right?"

"yes, this boy's personality can make sand, and Izr can control sand, right?"

"That's right, but it seems that there is also the ability to make objects sandy, and although it can be cooperated, it is not particularly important."

"Oooh......"

........

The discussions of the professional heroes, even if the Qin people heard it, they didn't react.

It's nothing to make flint sand, and Quartz Jixiong can indeed make various variants of quartz, but in terms of quantity, his own personality can't make that much sand.

You can't fill a truckload, and it's impossible to fill a quicksand river.

Quicksand River? That's a good name.

But then, he had to deal with the teachers and all sorts of people.

The consternation of those who know Quartz Jixiong can't be so simple as prevarication.

How about using "we haven't been together for a long time and haven't revealed our limits" as a reason?

While thinking, Qin Ren controlled the sand soldier quartz cixiong's fingers to compare into sword fingers, and with another high-pressure sand sword, he cut a medium-sized robot that was approaching in two.

However, the identity of Quartz Cixiong can be kept for fun, and when he wants to be a student, he can be a student.

Speaking of which, Snake Nine is almost at the end, right? After the start, she quickly crossed the field through the void, and now she was almost at the finish line.

Sensing the position of the snake Jiu, Qin Ren blinked, and continued to control the sand soldier quartz Cixiong to walk forward slowly.

And just as he walked forward slowly, the first echelon, to be precise, the second echelon, looked at the huge pothole with a diameter of more than 100 meters in front of him, and his face changed slightly.

In the pit dozens of meters deep, there are more than 100 huge stone pillars, like a stone forest, and between these irregular stone pillars, they are connected together by strong steel cables.

"That's right, after the robot hell, now you have the second difficulty in front of you!"

Mike teased the emotions of the students and the audience with his high-pitched voice:

“The Fall！ If you don't want to fall or get out, just crawl over it! ”

Professional heroes and ordinary people alike are horrified by the broadcast footage of the camera robot floating in the sky:

"It's too dangerous, isn't it?"

"A bunch of idiots."

And in response to their inquiry, Zach said dismissively:

"We dare to do this, of course, because we have safeguards! With his strength, he will definitely be able to catch everyone who falls! ”

However, his words made everyone applaud:

"Cut! How could I believe you! ”

"It's even more suspicious to say it out of your mouth."

"Are you Xiongying joking with the lives of your students?"

"Even if there is a recovery girl in your Xiongying, you can't make such a dangerous thing!"

"What the hell are you going to do! At least let's make sure first! ”

"If something goes wrong, you're responsible, understand!?"

Listening to the doubts of the professional heroes and the audience, Mike also raised his hand and said in a high voice:

PS: Whenever this happens, I habitually have the idea of being out of context. (tsk)

The teaching level of our starting class is still very popular. (Negative hand sighs)
