Roll back the time by 30 seconds a little, and then select "x0.1 times the speed" to watch, so that you may be able to know what just happened-

At the moment when Leo was about to step into the classroom, his brain began to run rapidly, and all kinds of data and possibilities appeared in his mind.

First of all, the average weight of the blackboard eraser is about 60g, and the blackboard eraser is about 50cm away from the top of X's head, and then according to the initial velocity is equal to 0, according to h=1/2gt2, t≈0.31s can be obtained.

In other words, it takes 0.31 seconds for the blackboard to fall to X.

Then analyze that the normal travel speed of an adult is 1m/s, and the distance of X Aotian is ......

In the end, all in all, in a word, (in fact, the author Jun really can't make it up), through Leo's analysis, at this time, the stickiness of lifting the blackboard eraser can just fall on X Aotian's head.

Everything was calculated without errors, and the landing point was almost perfect and impeccable.

Egg, however, all ignore one of the most critical issues......

That is, he is X Aotian!

Although X Aotian didn't notice that there was a blackboard eraser waiting for him above his head, as a strong man with the attribute of "invincible", how could he tolerate any dirty things to pollute his "boiled eggs"?

As a result, the so-called super instinct was activated instantly, and raising his hand was a punch, making the innocent blackboard eraser disappear directly from this world.

That is, the speed was adjusted to "x0.1 times the speed" to barely see what was happening, but this group of students who still lacked ability didn't know what was going on.

What happened just now was in an instant, too suddenly, and X Aotian shot too quickly, so no one reacted, in fact, even X Aotian himself didn't notice that a blackboard eraser fell off his head, and it was directly "eliminated".

Until now, there is still such an unsolved mystery in Class C: Where did the blackboard erase go?

"Huh? What's wrong? ”

Seeing that the students below reacted a little strangely, X Aotian asked curiously.

Everyone shook their heads, now they were more curious about where the blackboard eraser went, of course, some people wondered if it was X's own "personality" or ability that caused the blackboard eraser to disappear, and Leo's prank had actually been discovered by **Aotian, so everyone was a little nervous.

"Okay, just change your clothes and go to the playground if you're fine...... Well, what about the chalkboard? ”

Seeing that these students were a little abnormal, X Aotian thought that his powerful aura had shocked them, and he didn't pay much attention to it, and as he spoke, he was ready to wipe the blackboard and take them to the playground.

But after looking around, I found that there was no blackboard eraser!

"Gollum!"

The students collectively swallowed their saliva, their movements and expressions instantly stiffened, and they silently turned around to change their clothes, pretending not to know anything.

"This matter must be reported to the academy, doesn't Class C need to prepare a blackboard eraser? Outrageous! ”

Unable to find the blackboard eraser, X Aotian scolded and walked out of the classroom, and blew on the blackboard before leaving, blowing the powder on it all at once.

On the playground, the students of X Aotian and Class C were all in place.

A group of students wearing "Hero Academia" special sportswear (with easy movement and a certain degree of adaptability) stood there looking a little dazed, not knowing what X Aotian wanted to do when he brought them to the playground.

The "Hero Academy" is a graduate school designed to train future professional heroes, and the entire playground is quite magnificent, not only covering a huge area, but also well-equipped with everything.

"Hey, what are we going to do in the playground?"

Leo belongs to the straight character, and the blackboard eraser incident just now is put aside for the time being, and now he is curious about what X Aotian wants to do when he brings them to the playground, so he takes the initiative to ask.

The other students also looked at X Aotian with curiosity, not knowing what kind of medicine the latter was selling in the gourd.

"I believe you have already understood the characteristics of this academy before entering the 'Hero Academia', and one of the major features is the freedom of teaching!"

With his hands in his pockets, he began to explain to the students the purpose of coming to the playground: "Teachers have a lot of freedom when teaching students, whether it is lesson planning or evaluation of students, they are very free......

"In other words, all my courses will be according to my standards, and if I don't think I have the potential to become a professional hero, I can also report to the academy, and there is no need to stay here and waste time, understand?"

"Wow!"

As soon as X Aotian's words came out, the entire students of Class C exploded, they are not stupid, and they can naturally understand the meaning of X Aotian's words.

There is nothing wrong with the previous paragraph, the educational principle pursued by the "Hero Academy" is liberal education, after all, in the future, after becoming a professional hero, you need to be flexible and changeable, and there is no so-called conformity.

But the latter words made the students not calm, what is the meaning of "there is no need to continue to stay here and waste time"? The popular saying is that you will be expelled!

"Whether you like it or not, that's my way!"

"Okay, without further ado, let you come to the playground this time, just to do a simple ability test, I want to see what kind of level your perception of your own ability is, in short, it is to use your ability to complete some projects......"

"Remember, make the most of your abilities and get the best results, emmm...... I feel like this is a bit boring, you don't seem to have any motivation, in that case, then I decided to leave the academy in the last place in this quiz and do it! ”

With a slight smile, X Aotian announced the purpose of this trip, allowing these students to use their abilities to test, through this way, X Aotian can understand what kind of abilities they have, and when the time comes, they can be targeted and strengthened.

However, in order to give these students a sense of urgency, X Aotian proposed an overlord rule, that is, the last place in the test score to leave the "Hero Academia".

“！！！”

All the students suddenly became nervous, seeing that X Aotian's expression was definitely not a joke, they finally entered the "Hero Academia", and if they were expelled without learning anything, it would be really embarrassing.

"Without further ado, let's get started!"

In fact, the test of X Aotian is very simple, it is the kind of quiz that is usually used in physical education classes in school, including 100-meter sprint, long jump, repeated horizontal jump, pull-ups, and shot put.

The project is not difficult, but it is necessary to flexibly use your abilities in order to achieve better results.

The first thing to do was the 100-meter sprint, where X Aotian stood at the finish line to record the results, and then took out a report card that had already been prepared, showing the last best results of many students in each event before entering the "Hero Academy", and they were not able to use it.
