The main entrance of the college was wide open.

The east building fell straight and straight, lying motionless on the ground.

An Xiu shouted angrily, and the "Copper Mountain Iron Wall" magic power appeared on his body, but before the person arrived, the "Copper Mountain Iron Wall" was smashed, and the whole person spurted blood and flew upside down.

Rumble!

The upside-down figure smashed a rockery in the academy and buried it in the ruins.

I don't know life and death.

"Teacher!"

"Sir!"

"Courtyard Master!"

Yan Shan, Helian Shan and other students, as well as some of the teachings, were all stunned, and rushed towards An Xiu frantically.

"Teacher, teacher!"

Yan Shan was the first to rush and dig An Xiu out of the ruins.

"The teacher is fine. ”

An Xiu's face turned pale, and after breathing a sigh of relief, he struggled to his feet.

At this time, Helian Shan and other students, as well as the teachers of the academy, also arrived, and they were slightly relieved to see that the master of the academy was fine.

"Guard the hospital door!"

An Xiu said in a deep voice, and the figure flew towards the main entrance, and when he saw Donglou Xuan lying upright on the ground, he couldn't help but cry out sadly. He rushed up to pick up Donglou Xuan, turned around and handed it to the student behind him, and quickly walked behind the open door.

The atmosphere outside the gate was oppressive, and it seemed to be filled with billowing black fog.

He vaguely saw a blood-stained humanoid skin floating in the black mist, drifting towards the gate little by little.

This is the fourth taboo?

At the same time as his heart was shocked, his soul also trembled suddenly, as if he was frightened by the "forbidden" form, so that he had to close his eyes immediately.

The form of the fourth taboo is very strange and should not be looked at.

If you look at it for too long, you will definitely die.

But in a short breath of direct gaze, An Xiu also found some clues, and the door has been open for dozens of breaths. But the fourth taboo has never floated in, as if it didn't want to drift in.

It's something that's holding it back, making it very difficult for it to float in.

Why is that?

An Xiu closed his eyes and thought, his body motionless, as if he was in a stalemate with the fourth taboo.

This scene shocked the students behind them, the master of the academy was able to block the "taboo"? In their hearts, An Xiu's figure became extremely tall, as if it ran through the heavens and the earth.

At this time, An Xiu opened his eyes again and found that the humanoid leather had only floated in an inch.

But at this breath, his soul seemed to be frozen, and the blood in his whole body seemed to stop flowing......

His body was stiff and unable to move for half a minute, and there was only one door left in his mind.

I see!

An Xiu faintly understood.

Although the fourth taboo is terrifying, even the existence of the Great Sage level is like an ant in front of it. But it was stopped by a threshold, a door to be exact.

He didn't know why a door was able to stop the fourth taboo.

But it did stop.

As long as the door is not opened, the fourth taboo will never be able to enter the academy.

Even if the door is opened, there is a threshold that makes it difficult to cross. It can be crossed, but it takes a few moments......

That's why it's such a terrifying being, but it's going to knock on the door.

At this time, An Xiu immediately turned around, opened his eyes, and shouted: "Immediately seal all the courtyard gates!"

The priest guarding the gate of the courtyard was stunned for a moment, and seemed to realize something, so he immediately understood, and woke up: "Yes, seal the courtyard gate, seal the courtyard gate!"

The sober teachings and teachings immediately sealed all the courtyard gates.

But the main entrance could not be closed.

"Master, the main door can't be closed, what should I do?"

Some students said anxiously.

"If you can't close it, you will build another one. ”

An Xiudao, the figure appeared in front of the main hall in an instant, only to hear the sound of "boom", the front wall of the main hall and the door, etc., were demolished.

Rumble!

A wall immediately smashed down, blocking behind the open gate.

"Seal both ends. ”

An Xiu commanded, and he also sealed the door.

When everything was done, both the teachings and the students were relieved. At this time, they were also stunned, and they couldn't imagine that the door could block the fourth taboo......

It's simply unimaginable.

"Childe, this, this door, why can it block the fourth taboo?"

Liu Ling said with a tangled face, he was so confused that his brain was pumping, but he couldn't figure it out, he couldn't figure it out, and it made him very uncomfortable.

"It's up to the author. ”

Helian Mountain Road.

Tuk Tuk –

But the knock on the door rang again.

It was still so hurried, so that the consciousness of all the students fell into chaos in an instant.

At this time, more and more teachings could no longer resist the knock on the door, and their consciousness gradually fell into confusion. They frantically rushed to open the door, and when they couldn't open it, they began to smash and break down......

Burial Hill Academy.

Those who are still awake are only Anxiu and the Great Teaching.

"Please suppress the taboo by the white-clothed gentleman!"

The Great Priest roared and frantically stopped the Sect that smashed the door.

But there were too many gates, and he could block one or two gates, but he couldn't block all of them.

Eventually, his consciousness became confused.

At this time, An Xiu's face was pale, since even the door couldn't resist the fourth taboo, then turn the door into a wall!

Rumble!

Rumble!

Almost instantly, An Xiu demolished the main hall of the academy and sealed a wall behind the courtyard gate.

Without a door, how does the fourth taboo knock on the door?

But the knock on the door was still ringing.

Although An Xiu had sealed the courtyard gate with a wall, the door behind the wall was still there, and he felt that something was wrong at this time.

His consciousness also seemed to be in trouble.

But still a little sober.

As soon as An Xiu bit his tongue, he quickly came to the main gate, broke the "door" that he had moved in, and sealed a wall, so that the academy would have no main entrance.

He frantically broke down the courtyard gates one by one, and then sealed the broken doors with a wall.

When the last courtyard door was sealed, the knocking sound like a talisman finally disappeared.

He was relieved and said softly, "Hold the ......"

Bang!

He fell straight up.

Because in the process of breaking down the door and sealing the wall, he looked directly at the fourth forbidden form too many times, causing his soul and body to appear terrifyingly ominous.

Outside the main entrance of the college.

The blood-stained humanoid skin seemed to be frowning, staring at the wall in front of him. After breaking the door and sealing the wall, is it a wall or a door?

It seemed to be thinking.

"Woo-"

A whining sound came out of the skin's mouth, as if to say, "The door is the door."

It flapped again.

Tuk Tuk –

An eerie knock sounded again.

And the students who had just come to their senses, as well as the teachings, were all desperate. The doors are all turned into walls, can't they stop the fourth taboo?

Is the sky going to die and I will be buried in the mountain academy?

An Xiu, who had fallen, heard the knock on the door again, his eyes glared slightly, and a look of horror appeared.

Still not holding on?

Tuk Tuk –

The students and teachers in the academy fell into confusion again, and ran frantically to slam the door again.

Rumble!

Rumble!

They broke through the walls, revealing broken courtyard gates.

Outside the gates of all the courtyards, there was a blood-stained humanoid skin, which slowly floated into the ...... while opening its mouth and devouring the students

"Get out—"

An angry shout came from the burial mountain.

The humanoid skin stiffened, then trembled in the air.

......
