Just a few days.

All the students in the academy respected and feared Fan Wujiu.

The black ruler in his hand looked plain and unpretentious, with nothing special about it. However, when it hit the palm of the student's hand, even the holy realm could not reduce the swelling, and could only slowly wait for the swelling to subside.

"Ah, itchy, itchy..."

"It feels so uncomfortable. I want to cut off my left hand. What the hell is this?"

"Ugh, I don't dare anymore. I will study hard and never let down the dean's expectations again. Fan Xuezheng, I really know my mistake. Please forgive me..."

At this moment, many students in the academy are rolling around on the floor being tortured by their left hands, which is unbearable for them...

Countless students were afraid when they saw it.

"What kind of ruler is the ruler that I learned from Zheng? Why can't the swelling go away after being applied?"

"I don't know, I can't tell."

"This ruler was most likely made by the master of the academy, specifically to teach us."

Many students were discussing and became curious about the ruler in Fan Wujiu's heart.

This ruler is so magical and terrifying that it can't even reduce the swelling in the Holy Realm. Moreover, the Holy Realm is also unbearable, but it doesn't roll on the ground like Pluto.

But what's even more amazing is.

As long as you calm down and study seriously, the numbness and itchiness in your left hand can be relieved, and you will not even feel anything strange about your left hand. However, most of the students who are beaten cannot calm down, let alone study seriously.

At this moment, the emperors who were still in the Four Wastelands were all curious about the black ruler in Fan Wujiu's hand. Their eyes fell on the black ruler, but what puzzled them was that it was just a very ordinary black wooden ruler...

…

It's really ordinary and nothing special.

"It's strange, how could this happen?"

At this time, even the emperor became confused and couldn't help but study it carefully. However, after studying and studying, he found that the ruler in Fan Wujiu's hand was still an ordinary black wooden ruler.

"It shouldn't be, there must be something weird."

There was a great emperor who did not believe in evil and began to study it seriously again.

Shortly after.

They wanted to take the ruler away to study, but Feng Qingyan was in the academy, making them embarrassed and did not dare to take away the ruler rashly.

They are in the four wilderness areas and can study it without touching the ruler.

There is no need to take it away.

"Brother Panshan, do you see what's special about the ruler?"

The emperor pondered for a while and said.

"No."

Emperor Panshan shook his head, also studying the ruler carefully, and then said: "By the way, this ruler was made by my master?"

"I didn't pay much attention to it before, but when I think about it, besides the Holy Emperor, who else can create such a magical ruler?"

The emperor responded.

"It should have been made by the Holy Emperor."

Several great emperors nodded and studied the black ruler carefully.

At first, they really didn't pay attention to who made this black ruler. Who could have imagined that a small ruler could be so powerful?

Even they can't see through it?

When they noticed, Fan Wujiu had already finished beating five students.

"It's a pity that we didn't see the process of the Holy Emperor making the ruler, otherwise we would know something about it." The emperor shook his head, still very curious about the ruler, it was really amazing.

If the ruler is integrated into a weapon, will it increase its power?

besides.

Will the ruler work for them?

"I'm going to the academy."

There is a great emperor at this moment, but his figure is nowhere to be seen.

After a few breaths, several figures flew over. They were students from the academy, but their left hands were extremely swollen.

"What, what's going on?"

"Why can't I move? Why, how did I get here?"

Several students were frightened and struggling, but except for speaking, they were unable to move, and they had no idea why they suddenly left the academy.

It seems to be controlled by an invisible force.

At this time, they were fixed in the air. There were four Hades and one Holy Realm...

The few great emperors in the Four Wastelands were observing carefully, but they did not show up.

"But do you see the problem?"

After a while, the great emperor said.

"I can see some problems. It seems that the ruler is hitting the palm, but in fact it is hitting the soul." A great emperor said in surprise, "It's strange, how can this ruler hit the soul directly? Moreover, it has not hit the soul yet.

Disperse..."

"No wonder the swelling can't be reduced even in the holy realm. It turns out the problem lies in the soul."

"This ruler is really extraordinary."

Several great emperors couldn't help but marveled. They didn't expect that the small ruler turned out to be a soul-defeating artifact. Even for them, it was not easy to make a soul-defeating artifact...

Although it is said that this ruler hits their souls, it is neither itchy nor painful for them.

However, this is just the ruler of Jiuzhou Academy. It is not meant to kill or cripple students, it is just used to discipline students.

This shows what?

Also, students only need to calm down and study seriously, and the swelling will be reduced or even eliminated.

This is what's scary.

Even if they can create a soul-killing artifact that can disperse and cripple souls at once, it is not the power they can control to control the power.

At this moment, they could only marvel again, he was indeed the Holy Emperor.

"It turns out it's about the soul. I didn't expect that the Holy Emperor has such deep research on the soul."

The emperor was very moved.

Although they are great emperors, they don't know much about souls.

It's not that they haven't studied it, but they can't study it. After studying it, they still feel that the soul is just like that...

There is nothing to study.

"Could it be that the realm of creation is related to the soul?"

The emperor began to think seriously.

Although it was just a small ruler, they felt that the Holy Emperor's research on souls was no longer comparable to theirs.

Profound attainments.

"Creation is not necessarily related to the soul, but creation can definitely touch the soul." A great emperor hesitated and said, "Creation is the creation of all things. If it does not touch the soul, how can we talk about creation?"

"That makes sense."

Several great emperors nodded and couldn't help but look towards the academy.

Now that the problem was found, the emperor tried to reduce the swelling, but things did not go as he thought...

He was also unable to help the student reduce swelling.

"this……"

The emperor was stunned for a moment, frowned slightly, and said: "That's not right, why can't the swelling go away? The ruler hurts the soul. Logically speaking, as long as the mark on the soul is smeared, the swelling should disappear. But..."

"Can't reduce swelling?"

An emperor was surprised and took action himself.

After a while, several great emperors were shocked. They tried again and again, but still could not reduce the swelling.

"How is this going?"

Even the emperor couldn't figure it out at this moment.

"You see, there seems to be a faint trace of the ruler on their souls." After a few breaths, the emperor became surprised and said: "The ruler did not hurt the soul, it just left a trace on the soul..."

"However, this trace cannot be erased."

"Why can't it be erased?"

In the blink of an eye, half an hour passed.

Panshan and several other great emperors were still unable to erase the traces of the ruler from the students' souls.

Moreover, they were unable to study anything from the traces of the ruler, which seemed to be like a brand mark.

It doesn't seem right to say it's a brand.
To be continued...
