"Oh, the dean wants to solve the problem of the Eighteen Grottoes of the Dragon Head once and for all?"

Lin Feng was a little surprised, he didn't know much about the four forbidden places, but he also knew that the four forbidden places had always existed, and the nine sages of the human race didn't have any way.

"Sage Lin Feng, among the four forbidden places, in fact, the Longtou Eighteen Grottoes Forbidden Land is the weakest, and there are at least two emperor-level demons in the Longtou Eighteen Grottoes Forbidden Lands that we know. These two emperor-level demons are usually controlled by me. They are indeed very strong together, but they like to stay in the Longtou Eighteen Grottoes, and only occasionally leave the grottoes, they will be blocked by me. ”

"In addition to the two-headed emperor-level demons, this dragon-headed eighteen grottoes are still a very mysterious place, I used to go deep into it alone, but after feeling a strong threat, I was harassed by the two-headed emperor-level demons, so I had no choice but to quit. It's different with you this time, let's join forces, maybe we can completely kill the two emperor-level demons, and then explore the Longtou Eighteen Grottoes, solve this forbidden land once and for all, and remove it from the forbidden land!"

The more the Invincible Fist Saint spoke, the more excited he became, it seemed that he had been waiting for this day for a long time, and it was definitely not a temporary idea, but a plan. It's just that because of their lack of strength, the other eight sages couldn't pull away, and in the end they could only delay.

Once the problem of the Eighteen Grottoes of the Dragon Head is solved, it will not only be a matter of removing the name of the forbidden land, but it will also allow the Invincible Fist Saint to free up his hands to support other Sages, and maybe once it comes, the balance of the outer realm guarded by the Sage will be broken.

At that time, the situation of humanity will be much better than it is now.

"Dean, do you have a plan?"

"Of course, I'm waiting for your reply. ”

"Okay, since I became a sage, I have enjoyed a lot of benefits, but I have not made any contributions, this time I will accompany the dean to enter the Longtou Eighteen Grottoes!"

Lin Feng didn't have anything to hesitate about, he hadn't been a Sage for a long time, so Sage Kang and the others were also deliberately giving Lin Feng a little time to spend more time with his family.

In fact, the nine sages all had their own missions, and they were all sitting in the outer realms, and it was impossible for Lin Feng to enjoy this "benefit" all the time without making a single contribution.

Sooner or later, Lin Feng would help the other Sages to defend the Outer Regions together, it was better to help the Invincible Fist Saint solve the Dragon Head Eighteen Grottoes first, and then the situation of the entire human race would be very different.

Maybe in the future, a few saints will work together to solve the problems of the other three forbidden places one by one.

"Dean, when are we leaving?"

"I'll arrange the grotto base and I'll leave in an hour!"

So, Lin Feng waited quietly in the base, and by the way, he also learned some information about the Longtou Eighteen Grottoes.

About an hour later, the Invincible Fist Saint found Lin Feng.

"It's already arranged, Lin Feng Sage, I have to make it clear first, there is danger in the forbidden land, even I am not too sure, it may be full of too many unknowns, do you want to contact your family first?"

The expression of the invincible fist saint was very solemn.

Although the Sage is already the top powerhouse among the human race, almost invincible, the real master of the vast world is the fierce beast! What's more, there were some ancient and mysterious ancient civilizations, which may contain some terrifying means that can kill the Sage.

Like the four forbidden places, which are dangerous places that the saints believe may threaten the saints, the reminders and warnings of the invincible fist saints are not superfluous.

"No need, I have already arranged it before I came, not to mention, even if it is really dangerous, but if you want to kill me, I'm afraid it won't be so easy. ”

Although the forbidden place was dangerous, Lin Feng was still very confident.

"Haha, yes, as a sage, we shouldn't be so forward-looking, Kang Sage didn't let me take risks before, that was afraid of me alone, but we are dignified saints, if we look forward and backward, how can we still improve our martial arts? Let's go, go to the Longtou Eighteen Grottoes immediately!"

The Invincible Fist Saint flew out of the base directly, followed by Lin Feng.

For about an hour, Lin Feng saw that the ground in front of him was full of strange stones, and the surroundings were empty, except for stones and stones.

Moreover, the ground seemed to be shaking slightly, like an earthquake.

In the distance, a boulder looms over, looking like a giant dragon head.

"This is the Eighteen Grottoes of the Dragon's Head?"

"Yes, but this is only the ground part of the Longtou Eighteen Grottoes, and the real grottoes are underground. ”

"Underground?"

Lin Feng thought about it, and yes, the ground was bare, how could there be any grottoes? Therefore, the grottoes could only be underground.

"What's going on with the earthquake here?"

"It's not an earthquake, and I don't actually know why it shakes so often. But according to my speculation, the source of the vibration is in the depths of the grotto, and it is even very likely that there is a terrifying emperor-level demon!"

"Emperor-level demon, how huge is this?"

Lin Feng glanced at it, a radius of a hundred miles, it was shaking, if you count the underground, maybe the scope is wider, what kind of emperor-level demon is such a terrifying power?

"Haha, that's just my speculation. Alright, get ready, let's go down!"

"Go down, how do you go down?"

Lin Feng looked at the ground, there was no hole or anything like that, how could he enter the ground?

"Haha, of course it goes on like this!"

The Invincible Fist Saint laughed, and at the same time, a raging flame erupted from his entire body, as if the entire sky was on fire.

Behind him, a huge flame giant faintly appeared, unable to see the appearance, but exuding a terrifying momentum. This is a world of difference from when the Invincible Fist Saint descended on Longpan City.

This is the true strength of the Invincible Fist Saint as a Saint, and in the battle of Longpan City, the Invincible Fist Saint may not even show one-tenth of his strength.

"Boom".

The Invincible Fist Saint swung his fist violently, his fist was like a heavy hammer, and there were terrifying flames burning, turning into a flaming giant hand and slamming it on the ground.

"Boom".

The ground was shaking wildly, like a magnitude 10 earthquake, the shaking became more and more violent, and the terrifying shock wave spread out in all directions, leveling everything within a radius of a kilometer.

"Click".

Finally, cracks appeared on the ground, like spider webs, and then collapsed violently and rapidly, revealing huge holes one after another.

These giant holes continued to collapse, and finally all collapsed, forming a huge hole in the ground with a radius of 100 meters, which was deep and dark, and there was even the whistling sound of gusts of wind, exuding a mysterious and strange atmosphere.
