The stone was thrown down by Lin Fan for a long time, but there was no echo, which was enough to imagine how deep this cave mouth was!

"Boss, what are we going to do?" asked Nie Lei. ．

"Now that the entrance to the cave has appeared, we can't afford to delay time, we must go down as soon as possible!" Lin Fan said.

"I'll go down with you!" Miao Qiaomei said.

"You're gone, what will happen to your stockade?" Lin Fan asked.

"It's okay! This is our Miao territory, and it is difficult for outsiders to break in at will! Moreover, if there is really an ancient tomb below, then this ancient tomb is built under our Miao Zi, and it is a secret guarded by our Miao people, and you will definitely need my help sometimes!" Miao Qiaomei said.

Lin Fan pondered for a moment, then nodded and said, "Okay, then you can go down with me, if there is any danger, you will immediately return the same way, you can't follow us to the adventure!"

"Don't worry, I know it in my heart!" Miao Qiaomei said.

Immediately, Lin Fan said to Nie Lei: "Start doing!"

After Nie Lei comprehended what Lin Fan meant, he immediately put down the backpack behind him and opened it, and took out a tough rope inside!

Nie Lei and the others quickly moved and tied the rope to a sturdy object, and the other end was hung on their body with a hook!

At the same time, Nalan Qiankun took out a few night vision goggles, this kind of night vision goggles, in the dark, can see more clearly!

After the equipment was completed, Lin Fan did not hesitate, and said to Nie Lei and the others: "After going down, everyone gathers together, don't scatter!"

"Understood!"

Nie Lei and the others nodded heavily!

Immediately, the group no longer hesitated and slowly jumped out of the hole!

Below, it's so dark that you can't see your fingers, which makes you feel like you've come to hell!

Fortunately, Lin Fan and others have night vision goggles and can see some things clearly!

"Are they all down?" Lin Fan asked loudly.

"All in place!" Nie Lei reported!

"Descend immediately!" Lin Fan snorted, and then took the lead and descended downward!

At the beginning, Lin Fan and the others felt a trace of cold, but as he continued to go deeper, it became even colder, making people feel like they had come to a glacier, and they couldn't help but shiver up and down!

Moreover, the deeper you go, the darker it becomes, and even the night vision goggles don't have much effect!

"Turn on the flashlight!" Lin Fan hurriedly shouted, he had already taken the lead in turning on the flashlight!

Several others did not dare to hesitate and did so!

The light of several flashlights gathered together, and it was barely enough to illuminate the things within five meters in front of him!

After descending more than ten meters again, a thick layer of smoke appeared in front of me!

"There is a dense fog below, everyone be careful, don't disperse, if there is danger, you must shout, and then retreat!" Lin Fan cautiously told everyone!

"Understood!"

The crowd shouted in unison!

Then, Lin Fan took the lead, tried the rules, and immediately got into this piece of smoke!

Entering inside, people feel like they are wrapped in haze, the flashlight can't shoot far, and everything around them is difficult to see clearly!

Lin Fan's whole heart was in his throat, he didn't dare to be careless, he grabbed the flashlight with one hand, and the pistol on his waist with the other, as long as there was danger, he would shoot without hesitation!

The whole smoke, Lin Fan didn't know how big it was, let alone how many meters he had descended!

Time passed minute by minute, and not long after, Lin Fan finally appeared, and when the things in front of him were blurred clearly, he realized that he had walked out of that smoke!

Huhuhu~

And here, there was indeed a piercing sound of the wind, Lin Fan felt that he was being blown by the wind and was swaying from side to side, the cold wind couldn't help but be cold, and sharp, hitting people's faces, making people feel hot and painful!

Lin Fan didn't dare to be careless, and immediately turned his head and shouted, "Have you all arrived?"

"Number one!" Nie Lei shouted!

"No. 2!" Nalan Qiankun shouted!

"No. 3 ......" Junko shouted!

"Number Four ......"

"Number Five......

The voices of Xiang'er and Miao Qiaomei also came!

Knowing that everyone was not in danger, Lin Fan finally put his mind at ease, and said secretly in his heart: "It has been almost two hours since I entered the cave now, and there is a wind here, and it is estimated that it is not far from the bottom!"

"Be careful, everyone, keep descending!"

After Lin Fan snorted, he once again took the lead in the front!

A few people were like riding the wind and waves, breaking through the cold wind, almost an hour later!

Lin Fan felt that the wind had stopped, and here, there was no cold before, although the temperature was not very high, it was definitely able to withstand it, it was very different from the previous environment, as if entering another space!

"I guess we're close to the bottom now!"

Lin Fan smiled excitedly, and increased the drop!

Soon after, Lin Fan felt that his feet were stepping on a hard part!

Lin Fan didn't dare to be careless, stepped on it hard, and then bounced up with the help of his strength, worried that there would be dangerous things below!

However, Lin Fan waited cautiously for a moment, and did not show any dangerous aura, and only then did his feet step on the position of the sword shadow with confidence!

Then, Lin Fan put up the flashlight, and at the same time, with the help of night vision goggles, he saw that under his feet was a black and brown rocky ground, and around him, there was a high stone wall, and in front of him, there was a deep tunnel!

"Boss, have we reached the bottom?" asked Nie Lei, uncertain.

"If I'm not mistaken, it's like this!" Lin Fan said.

"Damn, is this the ancient tomb? The master has seen a lot of tomb robbers, and it is really the first time to come into contact with the ancient tomb, the spirit of heaven and earth, but there are no demons and monsters!"

Lin Fan was cautious in his heart, but he was also a little excited, firstly, he was getting closer and closer to the secret book of becoming the strongest left by the Taishang Ancestor, and secondly, he was also getting into contact with the ancient tomb for the first time!

"Boss, it looks like this thing is a mechanism!" At this time, Nalan Qiankun's voice came!

"Don't act rashly!"

Lin Fan hurriedly reminded him and walked quickly in front of Nalan Qiankun!

Lin Fan raised his flashlight to look, and sure enough, he saw that on a high stone wall, there was a protruding stone, just like the mechanism shape in those ancient tombs in the movie!
