Full career experience system Lin Yiji's face

No one in the other groups had any objection to Lin Yi's arrangement.

If it wasn't for them to block Mammon's support troops, he would be the one lying on the ground.

And in the entire Zhongwei brigade, they also instinctively believed that, apart from their own team leader, only team leader Lin could command themselves.

Lin Yi led a group of people into the water first.

The water surface is not too deep, about five meters.

For the people in the Zhongwei brigade, there is no difficulty.

When I came underwater, I quickly discovered the underwater passage.

The structure is a bit like the embedded parts of cement, but not quite.

Lin Yi instinctively believed that it was left by the predecessors.

But people of that era can actually make such a thing, which is amazing enough.

Along the underwater passage, Lin Yi climbed in first.

After entering inside, you can clearly feel that the direction is towards the ground.

This can effectively prevent the river from flooding.

A few minutes later, Lin Yi jumped out of the water, and the surroundings were pitch black.

Without the reflection of light, Lin Yi's night vision ability was greatly affected.

Turn on the searchlight and find that this is a confined space made of earth bricks.

There are many incomprehensible words on the wall, about 30 square meters.

After Lin Yi climbed up, other people also came up one after another.

There are more than [-] people in total, which is a little crowded.

The only way out here is the underground passage ahead.

Steps are made, extending in an unknown direction.

Adjusting the earphones, Lin Yi whispered:

"Pay attention to the people in each group, can you hear me?"

Soon, people in each group responded to Lin Yi.

"Every 5 minutes, people in each group must send feedback signals, and don't interrupt the connection."

"clear."

After arranging the tasks, Lin Yi focused his attention.

"Leader Ning and I are at the front, the others follow behind, and Leader Qiu and Leader Tao are at the rear."

Regarding Lin Yi's arrangement, the others had no opinion.

At this time, no other voices of opposition are allowed, because there is no time to discuss these things, and all the time must be used.

Taking out their weapons, the group descended the steps in a mighty manner.

Compared to the island, there is a big difference here.

There is a strong breath of life, and you can even see some things for eating and living.

"Here we are, there is no difficulty in breathing. Does it mean that there are other exits that allow air to flow in?"

"It's unlikely." Lin Yi said:

"I searched all over the place, but I didn't find any clues. Even if there were, they might not be nearby."

Lin Yi took the flashlight and shone it forward.

"If there is another entrance, it will be far away, and it will be difficult to pour here."

"If so, where does the oxygen we breathe come from?"

"I'm also a little puzzled. In short, there is nothing unusual now, so let's go and have a look first."

Under Lin Yi's reminder, everyone quickened their pace.

The steps stretched all the way down. Lin Yi estimated that it was about ten meters long and looked like a three-story building.

Soon, the group reached the end of the steps, and there was an empty field below, which was as big as a basketball court.

There are all kinds of things here, many of which are strange.

Not quite what life needs.

"Bath Ore!"

Xiao Bing exclaimed, and everyone looked after her voice.

I saw several pieces of ore the size of a human head.

This also solved the doubts in everyone's mind. It is because of these ores that they can breathe here.

This also confirms the previous speculation that the people living here are indeed aboriginals.

"Brother Lin, our previous guess seems to be inaccurate." Xiao Bing said:

"With Bath Ore, they no longer have to create a high-oxygen environment."

"You can't say that." Lin Yi said:

"With Bath ore, they can only meet their daily needs, but if they want to carry out large-scale activities, these Bath ore are far from enough."

The others didn't know what the group of people were talking about, so they could only listen quietly.

"But they can transport the ore here, so they don't seem to be the bottom of the aborigines. I don't believe that they don't have the intention of expansion." Lin Yi said:

"If you really want to live a comfortable life, the area of ​​Etilia Island is completely sufficient."

"So it is."

"Now is not the time to discuss these things. Let's take a look here to see if there is anything we can use."

"understood."

After receiving Lin Yi's order, all four groups took action.

Lin Yi looked around and found eight skeletons here.

After careful observation, I found something wrong.

The skeletons of these people are obviously thicker and longer than normal humans.

According to the shape of the bones, the height of these people is at least about two meters one to two meters two.

This scene made Lin Yi fall into deep thought.

In the ruins on the island, the bones of the aborigines were also found.

But their stature is generally short, only about 1.5 meters to 1.6 meters, and they don't feel like a race at all.

What is certain now is that this is where the aborigines live, but the race is completely different.

suddenly!

Lin Yi's eyes changed, as if he had thought of something.

The Hill of Death existed 2600 years ago.

In other words, these people were people who lived around 2600 years ago.

As for the people found in that ruins, there is still no way to deduce the specific age, so far, they can only guess roughly.

But what is certain is that it is much more than 2600 years.

There is no way of knowing how much difference there is in the middle.

Then it is possible that the bodies of these people have changed during this period of time.

Lin Yi frowned, according to the biological point of view.

Only in the case of rich oxygen can organisms undergo essential changes during reproduction.

But the current situation is far from meeting this requirement.

Are they experimenting with their own bodies?

This thought made Lin Yi shudder.

"Look here."

At this moment, Qiu Yuluo's shout called the others over.

Everyone gathered in front of a wall with a monster-like thing painted on it.

It has a bird-like head and wings, and a long tail.

At first glance, it looks very similar to the mythical phoenix, but upon closer inspection, it is quite different, because it has many feet, which makes it look mighty and weird.

"According to common sense, this thing is very similar to their totem."

Everyone stopped for a while, but they left without finding anything useful.

"Boss, there are new discoveries."

Hearing Shao Jianfeng's voice, Lin Yi trotted towards him.

There is a black jar in front of him.

There was something black and sticky inside, and there was a faint smell.

This made everyone fall into deep thought.
