After passing the interview and assessment test of the "Hero Academy", X Aotian and Saitama temporarily returned to Z City, returned to that reassuring small room, and still lived a poor life.

During this period, Saitama still worked hard to complete the daily "Stronger Training Plan" and steadily improved his strength.

At the same time, in the invisible place, Saitama's body gradually changed, reaching that critical value.

In layman's terms, Saitama is currently approaching the limits of human beings, and if you want to simply gain more power, you must break through this shackle, which can also be called a limiter, so that you can have power far beyond what humans themselves should have.

As for how to break through the shackles and break through the limits of human beings, this matter ......

"Teacher Aotian, it's been almost a month, and school should start soon, right?"

Saitama, who had finished training, asked curiously, it had been almost a month since they had returned from Y City.

X Aotian, who was watching TV, heard this, nodded, and felt that the time was almost up, guessing that the notice from the academy was just these days.

"Slippery (especially hairless) handsome pot, you have new news!"

At this time, there was a vibration and prompt sound from X's mobile phone.

Hurriedly picked it up and checked, it was the opening notice sent by the "Hero Academy", just next Monday, and as a "Hero Teacher", X Aotian needs to go to the academy in advance, and there are still many preparations to be done during the period, such as preparing for classes, familiarizing yourself with student materials, etc.

"Very good, Saitama, let's go!"

X Aotian didn't get too entangled and inked, and the next day he took Saitama to Y City, officially starting his life as a teacher in the "Hero Academy".

Saitama, on the other hand, entered the "Hero Academy" as a cadet.

……

"Saitama, you came out in a separate class, and you happened to be in the class I taught."

The day before the start of school, in the faculty dormitory, X Aoten said to Saitama that he already knew the specific class assignment.

The "Hero Academy" ushered in the first batch of students, although the popularity of the "Hero Association" is very high, many people who aspire to become professional heroes also flock to it, coming from various cities to become one of the members of the academy.

However, due to institutional reasons, the "Hero Association" heeded the advice of the blast and greatly increased the screening efforts, resulting in many people not being eligible for the opportunity to enroll.

Therefore, there are only 120 students in this year's class, which are divided into four classes: S, A, B, and C, and each class has exactly 30 students.

As I said before, according to the ability, personality, and potential of the students, the class they enter is also different, and the S class belongs to the elite level, and the level of becoming a professional hero in the future will be relatively higher.

On the other hand, Class C belongs to a group of students with poor strength, and they will receive relatively poor resources.

This is also the best solution at present, due to the lack of teachers in the "Hero Academy" not long ago, it is very good to be able to make up "Hero Teachers" who can just meet the teaching needs of all classes.

Perhaps in the future, when the "Hero Academy" is gradually improved, and then a large number of people with lofty ideals become "hero teachers", this differential education may be improved.

According to the previous interview and assessment test, X Aotian and Saitama are both rated "C", so they happen to be in the same class, which can be regarded as a kind of fate.

In addition, X Aotian happened to serve as the head teacher of Class C, and the respected teacher was once again sublimated.

Of course, in addition to the head teacher of X Aotian, the academy is also equipped with another "hero teacher" to assist in teaching, which is said to be an additional effort from the head of the academy to the "Hero Association", originally a C-level hero, although the strength is not strong, but the sense of justice is bursting, and the theoretical knowledge is also good, so he was selected to become the partner of X Aotian.

By the way, she is a girl and her hero is called "Axe Woman...... Axe, Woman, Emmm...... There is no sense of disobedience!

"Teacher Aotian, it's finally time to start the college life I'm looking forward to, I'll work hard!"

Saitama's face was full of excitement, as a young man who had already entered society, it was a novelty to return to the academy again.

"Well, even though we're Class C, it doesn't matter!"

"No matter what position you are in, keep a strong heart and don't let yourself be confused, you can continue to get stronger!"

X Aotian actually doesn't have much idea about class placement or anything, the main purpose of coming to "Hero Academy" is to make some money, and letting Saitama enroll is also for that scholarship and free tuition.

"Speaking of which, Teacher Aotian, I found that the speed of strength improvement has slowed down recently, what should I do?"

Saitama realized that the speed at which his strength was increasing had decreased significantly, and asked the doubts in his heart, because he was far from the strength shown by X.

Touching his chin, X Aotian fell into deep thought.

He also noticed this problem, but he didn't know what the specific reason was, his strength was because he was born with the attribute of "invincible", which made no sense, asking is the setting!

And making Saitama gradually stronger is just a training plan made up casually by X Aotian (I didn't expect the effect to be outstanding), so encountering a bottleneck caught X Aotian a little off guard.

"Well, don't worry, this situation has been encountered by the teacher, this is the so-called bottleneck, and the teacher calls it the 'four locks and shackles'!"

X Aotian deserves to be X Aotian, as a respected teacher, the ability to talk nonsense is the first! This is simply a small scene, with a flash of inspiration, another imaginary "setting" was born-

"People have four locks, called heaven, earth, Xuan, and yellow!"

"And these four locks are hidden in the human body, ordinary people don't know their existence at all, it is them, all the potential of people is locked, once opened, it can completely stimulate the potential and obtain explosive enhancement!"

"Of course, it is not so simple to open them, you have to take them step by step, step by step, and hit a lock when a critical saturation is reached at a stage, so that you have a chance of success."

"Now you need to open the first lock, the 'Yellow Body Lock', break through the limitations of the 'human body', and call it the 'Body Pole' for the teacher!"

X Aotian brags that he never has to make a draft.,Just open your mouth.,Anyway, Saitama doesn't know if what he said is true.,Anyway, just make a "setting".,Is it possible that someone refutes it?

Saitama was bluffed and stunned, hearing so many bizarre proper nouns, he was completely in a state of confusion, and of course he chose to believe in X Aotian at this time! Hurriedly took out a small notebook and wrote it down.

Seeing Saitama cooperate with him so much (the second second), X Aotian is very pleased, this apprentice is really teachable!

"Okay, Saitama, you should work hard to open the 'Yellow Lock' first, don't give up your previous training, you must accumulate so that you have a chance to succeed, understand?"

"Yes, Aotian sensei!"

The daily life of Secondary 2 teachers and apprentices, looking forward to the start of school tomorrow!
