Knowing the seriousness of the matter, as a six-star famous teacher and dean of the famous teacher college, there was no reason to refuse, so Zhang Hang agreed.

Back then, Master Confucius had also visited the cave three times, and he also wanted to see what this node bordering the extraterritorial battlefield of the alien spirit people looked like.

"There's Dean Lao Zhang......"

Master Mu respectfully clenched his fists.

"It should be done!"

Nodding, Zhang Xuan didn't say more, and immediately communicated with the deity who was cultivating outside, and after a short time, a figure appeared in front of him.

It's the deity.

As the other party said, with the help of the dean's order, you can really come here.

After glancing at each other and quickly knowing what was happening, the deity immediately looked at Master Mu.

"Open the formation, I'll go down and have a look!"

"Master Zhang is careful, you just need to see what happens, if you can't find it, it's okay, you can think of a way slowly, don't be greedy for merit, and there will be danger......"

Master Mu explained.

It is important to investigate the reason, but the person in front of him is a famous teacher, and safety is even more important.

"Don't worry, I've always been cowardly, and I won't rush forward knowing the danger!" Zhang Xuan smiled.

With his means, if he can't fight, he can still escape.

"That's good......"

Hearing his promise, Master Mu breathed a sigh of relief, returned to his position, grabbed forward, and a crack immediately appeared in the sealed formation.

After studying this formation for tens of thousands of years, it is still very easy to make a crack appear in a short period of time, but it is still very easy to do without delaying to block the killing qi.

"Farewell ......"

Without the slightest hesitation, his body shook, and Zhang Xuan rushed straight towards the crack.

The body entered it, and the "Whew!" disappeared.

"He's not in danger, is he?"

As soon as he disappeared, the figure of a dean appeared in front of Master Mu.

"Don't worry, when Master Confucius was a half-saint, he also entered the cave, and he came back unharmed, he is also a famous teacher recognized by heaven, this Master Zhang will definitely be able to solve the hidden danger this time!"

Mu Shidao.

"I hope so......"

The dean nodded, his brows still worried.

In the cave, many of the peak powerhouses of the Holy Domain, when they enter it, they basically have no return, this person who only has the strength of a half-saint can really be safe and sound?

He was a little worried.

"It's useless to worry, the current situation, you don't know it, you can't stand it anymore...... During this period of consumption, the minds of those of us have run out of oil and will die at any time, and if we don't solve the problem as soon as possible, I'm afraid...... It really will cause irreparable disaster!"

Mu Shi shook his head with an ugly face.

It's not that he wants the other party to enter the dangerous place, it's that there is really no way.

Their thoughts themselves are not strong, and they have been tortured by these killing qi for more than two years at this moment, if it weren't for their firm thoughts, I am afraid that their souls would have been scattered and disappeared long ago.

And how can it persist until now!

"To become the dean of the college, you have to shoulder the responsibility of the dean, and if you want to grow, it can't be smooth sailing...... This is a famous teacher, Master Zhang knows this!"

Mu Shidao.

"Yes!" said the dean.

Yes, a famous teacher is not only an honor, but also a responsibility.

How can you become a real teacher if you even retreat from your own responsibilities?

This Master Zhang, although young, is obviously doing what a true teacher should do.

......

"This is the Cave?"

Feeling his whole body tight, Zhang hovered and stood up straight, only to realize that he had come to a huge underground world.

The surroundings are as dark as ink, there is no light, I don't know how deep and far, I can't see the end at a glance, there is a strong killing aura everywhere, it is extremely cold, it makes it difficult to breathe, if I don't know in advance, I think I have fallen into the boundless hell.

"No wonder no one wants to come ......"

When it comes to the cave, all the famous teachers talk about the tiger changing color, and now it seems that it is indeed not a place for people.

These killing qi alone can make those who are low in cultivation feel fearful and their state of mind collapses.

It's as if at the beginning of the assessment of a four-star famous teacher, Master Hong took out a person from the alien spirit clan, and everyone didn't dare to move forward.

The killing aura here is extremely strong, and it seems that there are many fierce monsters hidden around it, which will be killed at any time.

A five-star master who has not undergone special training will immediately tremble with fright when he suddenly enters, and it will be difficult to move forward.

"Once these breaths leak out...... At least 99% of the people in Hongyuan City will die on the spot......"

The look was solemn.

Before, I didn't think anything, but when I came here, I knew it was terrible.

With such a strong killing aura, it is easy for those who are not strong in cultivation to lose their minds, lose themselves, and become killing machines.

Once leaked to Hongyuan City, this city containing hundreds of millions of people is very likely to become ruins and deserted in a short period of time.

The Heavenly Dao True Qi was running, and the oppressive feeling of the Killing Qi disappeared, and Zhang Xuan raised his eyes to look around.

The scenery is basically the same, it is all pitch black, and even if you use the Eye of Reason, you can only see the distance within a few hundred meters.

Difficult to discern directions.

"Follow the breath, you will definitely be able to go to the depths......"

The stronger the killing aura, the more he went to the depths of the underground palace, stood in place and felt it, Zhang Hang found his direction, and walked straight forward.

There is not only a killing aura around, but also some strange magic sounds, bewitching the soul, and the mood is not strong, listening to it for a while, I am afraid that you will fall into it, unable to extricate yourself, and finally you don't know whether you are alive or dead.

"No wonder famous teachers have such strict requirements for the mood scale, and it is estimated that it will be difficult for a martial artist of the same strength to last here for a long time!"

Looking around vigilantly, Zhang Xuan walked forward slowly.

The cave filled with killing qi not only makes people dizzy, but more importantly, it also blows a special magic sound, and the mood is not strong, and it is very easy to indulge in it.

Not to mention anything else, even if it is a demi-saint powerhouse, if you stay here for a long time, you will go crazy.

However, these things had no effect on him, and under the operation of the Heavenly Dao True Qi, his mood was vast and spacious, and his spirit was not affected in the slightest.

"Hmm, there are footprints of alien people!"

After walking forward for a while, Zhang Hang frowned.

The ground not far away is covered with dense footprints, about a foot long.

He had seen the Aliens, who were usually taller than normal humans, and the footprints, so deep in the ground and so huge, were probably left by them.

It's just that...... Isn't there a seal in the depths of the dungeon?

How can there be aliens here?

"And human footprints......"

After walking in the direction where the footprints appeared for a while, Zhang Hang saw scattered human footprints, which seemed to have traces left by the battle.

It seems that there are humans and aliens who have met and fought.

There are human beings in the caves, and he has long known this, basically they are famous teachers who cannot break through or have reached the end of their life, and in order to take a higher step, they come here regardless of life and death.

"These traces have not been left for a long time, and the alien people are numerous, and they have the upper hand...... If it's fast, you might even be able to save someone!"

The eyes of reason flickered, and after looking at the traces for a while, he raised his eyebrows.

According to the traces, it can be seen that the alien people have a great upper hand, and the Terrans should have fled after being chased.

"Anyway, let's go over and see ...... first."

As a famous teacher, it is impossible to see human beings in distress and stand idly by.

Hongchen walked in the sky, gently levitated, and flew straight along the direction of the footprints.

After cultivating the Divine Sealing Solution, the true qi in his body was extremely thick, and the consumption of maintaining flight was already negligible.

Covering all the breath on his body, his eyes flickered, and the speed was fast.

In such a dim place, if you change to other six-star famous masters, you must be cautious, but for him, the eye of reason can not only see the texture, but more importantly, see farther, even if there are really alien people, they must find each other first.

After flying for half an hour, although there was still no human figure in sight, the ground traces became denser and denser, and the battle became more and more fierce, marking that the distance between the two groups of people was already close.

After walking forward for a while, I really felt a violent aura stirring in front of me, and there seemed to be a battle going on in front of me.

The closer he got to the front, the more he calmed down, closed the acupoints of his body, and slowly flew forward, bypassing a hill, and sure enough, he saw a group of alien people standing in front of him.

"This ......"

glanced at it, and his eyebrows jumped.

There are as many as two hundred of these alien spirit clansmen, and each of them has reached the first level of the Holy Domain, and there are even a few of them who are double of the Holy Domain.

Fortunately, he suppressed his breath in advance and was not discovered, otherwise, even if the Thousand Ant Hive had the Nine Kings, the Purple Yang Beast, and the Jin Yuan Ding, and fell into it, he would only be beaten by the group.

The alien spirit race, naturally strong, is a fighting nation, in the same level, each one is stronger than the holy beast, two hundred heads...... Not to mention him, even if the four powerhouses of the Holy Domain come over, I am afraid that they will be blown up on the spot.

"How can there be so many?"

The face is ugly.

More than two hundred heads of the Holy Domain are heavy, plus several heads of the double, although they can't sweep the entire Famous Teachers Academy, but rushing into Hongyuan City, I'm afraid no one will be able to stop it, at least the Hongyuan royal family, definitely can't resist!

Where did all this stuff come from?

"It is estimated that the impact under the mausoleum is caused by the joint attack of so many alien people...... Otherwise, it would be impossible for there to be such a huge movement, so that more than a hundred deans in the past dynasties, as well as so many deans' orders, would not be able to resist!"

Zhang Hang understood.

The ideas of more than a hundred deans, combined with the seventh-level formation, are infinitely powerful, and more importantly, there are more than 100 dean's orders, containing millions or tens of millions of students.

It is estimated that it is this group of alien people who are doing the trick.

"Who are they fighting?"

Eyebrows raised, looking inside.

Immediately, I saw a group of old men wearing famous teachers' robes, back to back in a circle, covered in blood, and each with death in their eyes.

"They are all six-star peak masters......"

They are all six-star peak teachers, and there are as many as thirty or forty people.

"Huh, Lu Feng?"

Suddenly, a familiar figure appeared in sight.

(When I arrived in Changsha, is there an old iron in Changsha? I caught a day of planes, and I actually used my mobile phone to code 6,000 words, yes, I am the peerless genius of one in ten thousand!)
