The giant tooth mechanism at the front entrance of the thatched shed is very simple and rude.

If someone carelessly walks there directly, once the mechanism is touched, the mechanism hidden in the yellow sand will be activated, and then a giant tooth will be drilled out and the person will be bitten into pieces.

The giant tooth is like a crocodile's mouth, built more cleverly, no matter which direction the mechanism is touched, there seems to be a spring gear underneath, which will turn flexibly, and then it will immediately bite in that direction, the speed is very fast, and the attack power is also very fast and rough.

Now the mechanism tooth has bitten the wood and then burrowed into the yellow sand, and it is not a one-time mechanism, but can be triggered multiple times.

However, the principle of this mechanical creation is also very simple, and it is easy for modern people to understand and find its flaws.

Master Lian went to find a wooden stick about five meters long, and then asked the black girl to pick up a stone, Master Lian stabbed the next mechanism contact with the wooden stick, and then the giant tooth quickly drilled out.

It was at this time that the black girl quickly threw the stone into it after the giant tooth came out, and the mechanism was half opened, because the width of the stone and the giant tooth could not be closed, the giant tooth mechanism could not shrink back again, and it was stuck there.

But after it was stuck, the giant tooth was still opening and closing, as if it would not stop biting the stone.

"Go quickly, don't be too big, don't be too fast, there must be a trap in it, the simpler the place, the more dangerous it is, you must remember this!"

After Master Lian had given everyone a word of advice, he took the lead with a wooden stick and passed through a gap next to the megalodon, and the others hurriedly followed.

After entering through the door, the ground inside was covered with yellow sand, and after hundreds of years of immersion, it appeared relatively smooth, as if there was no trace of living creatures passing through it.

Master Lian used the most primitive method, which was to make the stick poke a few times in some places to see if there were any gaps or the presence of hard substance.

But under such a stab, I really tried out that some places seemed to be deep pits above the ground, and the bottom was full of metal spikes, but it was also a simple way out.

It's just that Huo Sifar saw that Master Lian actually used such a simple method to explore the way, and she really couldn't stand it anymore, so she took out a small robot explorer from her backpack.

After activating the robot explorer and connecting it to the remote control, Huosfar released the small robot detector, and soon some of the conditions of the road surface and the detection analysis map three to five meters below the ground were displayed on the monitor on this side.

Xu Ran looked at the detected images on the side, although they were relatively clear, but there were still uncertainties in some places, which made him start to miss his robot team.

The goal of the group was the pyramid buildings, as well as the ancient tower in the center.

There seems to be a square in the middle, which seems to be relatively open, but it is not necessary to probe all the parts.

After using a small detection robot to circle around the middle, there was probably a path that could be passed smoothly.

In fact, under the yellow sand, there is really an old-fashioned road, and everyone steps on the old-fashioned road, and the safety factor is much higher.

But just as he was about to reach the front pyramid building, the black girl who was walking in the front came to a slightly protruding part and was about to step over, when suddenly a sudden change occurred.

Wow!

The ground began to shake before the feet of the black girl fell, as if something was about to come out from under them.

This scene shocked everyone, and even the master felt that the ground around him was shaking very strongly, and he couldn't help but change his face, and said, "Quickly retreat ten meters!"

Everyone quickly retreated ten meters along the way they came.

At this moment, a metal spike suddenly burrowed out of the ground.

The metal spikes were very sharp, and they were arranged very densely, and they quickly drilled out from different positions, and if one accidentally stood in the place where the spike was, the body would definitely be pierced and hung with sausages.

The spikes were about three meters high, very pointed, very thin and dangerous, arranged in an irregular way, and it seemed that there was no pattern to be found, even if Huo Sifar used the detection robot to continue to detect through the first row of spikes, but there was no new discovery.

However, it is known that there must be such spikes hidden elsewhere.

I really didn't expect that this kind of seemingly simple main sacrificial shrine would be camped step by step, full of traps and traps.

Fortunately, it seems that most of the people here are metal or mechanical artifacts, and there are no highly poisonous mutated creatures for the time being.

Da-da-da-da!

The first row of stabs was because everyone came to the front, and the mechanism there was suddenly touched and bounced out, and even the master took a wooden stick and stabbed it in other places, feeling that the ground was hard and there was no gap, but when the black girl walked a few steps, there was a sudden spike in an unknown place and suddenly drilled out.

Fortunately, the others didn't follow, otherwise even if they were scattered and didn't get close to other directions, I'm afraid that Leng Buding would have a spike out and stab people through.

Anmoko looked at the spikes, and suddenly said: "Since the robot can't detect these mechanisms, it means that this should be a gravity mechanism, and a few of us walk in one place, and the mechanism will be triggered through gravity induction, so why don't you try to act alone?"

Huo Sifar listened to Amoko's suggestion, thought about it and nodded, "Let's try it first, then who will go first?"

"Come on, it's the Guardian's job!"

The black chick volunteered to take on this task, and then slowly walked towards the road that seemed to be nothing.

Shout!

Just after the black chick took a few steps, suddenly a spike popped out next to her, the black chick did not panic and continued to walk, every few steps she walked, there would be spikes in different directions popping up, some would block her way, and after she bypassed, it would continue to pop out.

But soon the black chick discovered a pattern, that is, when the single passes, those spurs pop up nearby, and there is no direct threat to the black chick's spikes.

The others remained where they were, until after a little while, when the black man had reached a safe route about twenty meters or so, and she stood on a stone platform in another place and probed, and no more stabs bounced.

After calculating the line of the black girl, the second is Master Lian, when he walked along the line of the black girl, although the position of the spike changed, but the line was relatively safe for the single person to go forward.

However, just when Master Lian had walked less than ten meters on this line, something happened on the side of the black girl.

Everyone was surprised to see a big hand suddenly poking out of the sand and grabbing the black girl.
