"Oh? The dean wants to solve the problem of Longtou Eighteen Grotto once and for all?"

Lin Feng was a little surprised. He actually didn't have much understanding of the four forbidden areas, but he also knew that the four forbidden areas had always existed, and the nine human saints had no choice.

"Saint Lin Feng, among these four forbidden areas, the Longtou Eighteen Grottoes are actually the weakest. In the Longtou Eighteen Grottoes we know, there are at least two emperor-level monsters in the Longtou Eighteen Grottoes. These two emperor-level monsters are usually controlled by me. They are indeed very strong in joining forces, but they like to stay in Longtou Eighteen Grottoes, but they will occasionally leave the cave and will be blocked by me."

"In addition to the two emperor-level monsters, the Dragon Head Eighteen Grotto is still a very mysterious place. I have gone deep into it alone before, but after feeling a strong threat, I was harassed by the two emperor-level monsters, so I had to withdraw helplessly. This time, it will be different with you. Let's join forces, and maybe we can completely kill the two emperor-level monsters. Then explore the Dragon Head Eighteen Grotto, solve this forbidden area once and for all, and remove it from the forbidden area!"

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. It was definitely not a temporary idea, but a plan. It was just because of his lack of strength that the other eight saints could not pull away, so they could only delay it.

Once the problem of Longtou Eighteen Grottoes is solved, it will not only be a matter of eliminating the forbidden land, but also allow the Invincible Fist Saint to free up his hands and support other saints. Perhaps the balance of the external domain guarded by the saint can be broken all the time.

By then, humans will be much better than they are now.

"Director, do you have a plan?"

"Of course, I'll wait for your reply."

"Okay, since I became a saint, I have enjoyed a lot of benefits, but I have never made any contributions. This time I will accompany the dean to visit the Longtou Eighteen Grottoes!"

Lin Feng had nothing to hesitate. He didn't have long been a saint, so Shengzhe and others were also deliberately giving Lin Feng some time to spend more time with his family.

In fact, the nine saints all have their own tasks and are all in the foreign domain. Lin Feng could not have enjoyed this "benefit" all the time without making any contribution.

Sooner or later, Lin Feng will help other saints to guard the outer world together. It would be better to help the Invincible Fist Saint solve the Longtou Eighteen Grottoes first. The situation of the entire human being will be very different.

Maybe the saints, together in the future, can solve the problems of the other three forbidden areas one by one.

"Dean, when will we set out?"

"I will arrange for the matters of the cave base and set off in an hour!"

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

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

"It has been arranged, Saint Lin Feng, I have to make it clear first. There is danger in the forbidden area, and I am not even sure. It may be full of too many unknowns. Do you want to contact your family first?"

The expression of the Invincible Fist Saint is very serious.

Although the saints are already the top strongest among humans and are almost invincible, the real master of the vast world is a ferocious beast! What's more, there are some ancient and mysterious ancient civilizations that may contain some terrifying means that can kill the saints.

Like the four forbidden areas, they are dangerous places that the saints believe that may threaten the saints. The reminders and warnings of the Invincible Fist Saint are not redundant.

"No need, I have already made arrangements before coming. Besides, even if it is really dangerous, it may not be that easy to kill me."

Although the forbidden area is dangerous, Lam Lin is still very confident.

"Haha, yes, we shouldn't be so savage as saints. Saint Kang shouldn't let me take risks before, because we were afraid that I was alone, but we are dignified saints. If we look forward to the front, how can we improve our martial arts? Let's go to Longtou Eighteen Grottoes immediately!"

The Invincible Fist Saint flew directly out of the base, and Lin Feng followed closely behind.

About an hour later, Lin Feng saw strange stones everywhere on the ground in front, and the surroundings were empty, except for the stones.

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

Further away, a huge rock stood faintly, looking like a huge dragon head.

"This is Longtou Eighteen Grottoes?"

"Not bad, but this is just the ground part of Longtou Eighteen Grottoes, and the real Grotto is underground."

"Underground?"

Lin Feng thought about it and said that there were no grottoes on the ground. Therefore, grottoes can only be underground.

"What's going on here?"

"This is not an earthquake, and I actually don't know why it vibrates here from time to time. But according to my speculation, the source of the vibration is deep in the cave, and it is very likely that there is a terrifying emperor-level monster!"

"Imperial-level monster? How huge is this?"

Lin Feng took a look and found that the area within a hundred miles was shaking. If it were included in the ground, the range might be wider. What kind of emperor-level monster has such a terrifying power?

"Haha, that's just my guess. Okay, be prepared, let's go down!"

"How to go down?"

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

"Haha, of course this is how it goes!"

The Invincible Fist Saint laughed, and at the same time, a blazing flames emerged from his body, as if burning the entire sky.

Behind him, a huge flame giant appeared faintly. He couldn't see clearly, but exuded a terrifying aura. This was a world of difference from when the Invincible Fist Saint came to Longpan City.

This is the true strength of the Invincible Fist Saint as a saint. In the battle of Longpan City, the Invincible Fist Saint may not even have one tenth of its strength.

"boom".

The Invincible Fist Saint waved his fist violently, and his fist seemed like a heavy hammer, and the terrifying flame burned, turning into a giant flame hand and hitting it hard on the ground.

"Rumbling".

The ground was shaking wildly, like a magnitude ten earthquake, the vibration became more and more violent, and the terrifying shock wave spread in all directions, razing all places within a radius of 1,000 meters to the ground.

"Click".

Finally, cracks appeared on the ground, like spider webs, and then collapsed violently and quickly, revealing huge holes.
