Fast Forward To three thousand and seventy seven

Under the leadership of Xu Jiu, the members of the expedition climbed the convex platform at the height of the rock wall through vines.

As soon as he stood firm, a cave appeared in front of everyone.

In addition to the mucus and a large number of claw marks left by the monster after crawling on the ground of the cave, there is still a track extending to the interior of the cave, and a track vehicle with a somewhat similar shape to the mine car is overturned not far away.

Fluorescent insects fly to the top of people's heads, and the light is projected on all sides. At the same time, there are many holes of different sizes on the rock wall not far from the upper left.

Because there is a certain distance between them, it can only be judged by the contour. Some of them are artificially excavated with flat edges, while the other part is like digging through with brute force, and the scale is also different.

There are openings that can only be used by one person, and there are openings that are more than ten meters high, which makes people suspect that they may be used for giants.

"Look there!"

Colonel Zongze suddenly raised his hand and pointed to a hole on the right. They all looked at it. They saw that a gray brown tail was gradually disappearing in it.

"Monster's nest?"

Glancing at the hole in front of his eyes, the secret instrument swallowed his saliva and asked in a muffled voice.

No matter how well prepared you are, as long as you are a normal person, you will fear the emergence of this giant monster, especially in the current dark environment.

"You guessed right, but it's not the nest of the monster you think. What was dragged into the hole just now was the body of the python we ran into on the top. When I came up just now, there was a small half hanging outside. It was dragged in only a minute or two."

Xu Jiu was inevitably surprised to see the Python's body here. You know, the python was on their head at that time. Even if it deviated from the falling position, it shouldn't be too far.

The expedition was at least a kilometer from the point of fall.

In other words, the python that can drag its weight by ton here in such a short time will either have great strength or act in groups.

This is also part of the reason why Xu Jiu guessed right about the secret ceremony.

"There may be many monsters hidden in the cave... Do you want to go in?"

Zheng Yi was uncertain for a moment. Her intuition told him that there was a great danger hidden in the cave. She subconsciously looked at Xu Jiu.

"This is probably the real residence of the relic civilization forces stationed here at that time. Nine times out of ten the monster we saw just now was transformed inside. In that case, there may be a secret about the temple inside the cave."

Xu Jiu actually wants to go in and find out, but he is not the leader of the expedition. Strictly speaking, he is just a consultant. Therefore, he is not prepared to force others to follow his own pace, but to put forward his own opinions,

"If we are lucky enough to find a station related to the temple, we may also find a channel directly connecting the other end of the valley, that is, the seal place where the temple is located."

"Then go in!"

After a brief silence, Zheng Yi was persuaded by Xu Jiu and signaled the team to move forward.

After entering along the track on the ground, he took more than a dozen steps. A little white light appeared in front of him. Xu Jiu motioned the team to put away the fluorescent insects. The light blue fluorescence they projected was very eye-catching in this environment.

There was no way before. Now there is a natural light source to replace it. Naturally, there is no need to continue to maintain it.

Further along the road, the source of white light appears, and gray crystal clusters appear on the rock wall inside the cave.

Unlike any ore seen in the past, the interior of these spars is like being injected with a flowing liquid. Even if they are embedded in the rock wall as a whole, the energy inside the spars is still churning.

When Xu Jiu saw them, he reached out and broke a small piece in the palm of his hand. He rubbed it quietly for a few seconds. A flash of surprise flashed in his eyes. He immediately inserted it back into the stone and broke back a larger piece as a lighting object.

The people behind them learn from each other, and they all get pure natural "flashlights".

With the deepening of the group, the cave passage gradually became spacious like a trumpet until Xu Jiu noticed the environment in front and suddenly raised the crystal stone in his hand, and his vision suddenly opened.

They arrived at a small grotto.

Everyone's eyes locked on the half open gate at the other end of the cave for the first time.

Walking quickly, Xu Jiu noticed that a large amount of dust accumulated on the door panels on both sides, and the tracks left by the injured monster could be seen on the ground in the middle.

"You see, there is only the passage when we came inside the grottoes. Are the other holes we saw outside leading to other places?"

Madeleine asked as she walked around the grottoes with crystal pillars.

The gate in the cave proves that Xu Jiu's previous speculation is undoubtedly correct. Here is the real camp, but there is only one channel directly here, and people have to care about what happens in other places.

"Just go in and have a look."

Just spinning around in the grottoes won't understand anything. Xu Jiu crossed the thick door while talking.

Almost as Xu Jiu stepped into the space behind the door, the dripping sound from the darkness made him alert quickly, handed the crystal stone in his hand forward, and the perception spread out immediately.

With his superior eyesight, even with a weak light source, Xu Jiu saw the internal structure of the cave.

Originally thought it would be filled with all kinds of old appliances, but there were a large number of pools in the space!

Yes, except for the entrance area where Xu Jiu stands, there are pools with a diameter of about two meters, tamped with unknown materials and a height of nearly half a meter, two steps closer to the nearest one, which has already dried up.

Where did the dripping sound come from?

Without taking care of the members of the expedition behind him, Xu Jiu took a step and leaned in the direction of the sound. Soon he found a pool that had not dried up in the middle of the grottoes, and also saw the monster lying on the edge of the pool.

At this time, it was dying, and half of her arms were soaked in the water. What made Xu Jiu quite concerned was that the wound opened by Madeleine showed some healing at the moment, and there were a lot of water stains around.

"Is he trying to save himself with the water in this pool?"

Zheng Yi, who followed behind, saw the scene in front of Xu Jiu, noticed the monster's intention and asked in surprise.

"I'm afraid so. Why do they build so many pools here? It's not for bathing... Zheng Yi, feel whether the water in this pool contains evil energy."

Xu Jiu doesn't think that people of relic civilization will be so clean that they will build an underground bathhouse nearly kilometers away from the earth's surface. Besides, how can the monster think of using groundwater to recover his injury?

"The water is full of evil energy!"

He picked up a handful of water and still slipped between his fingers. Zheng Yi tightened her eyebrows and said in a deep voice.

"That's right. It knows that there is a pool full of evil energy. The water in it can repair the wound..."

In the interval of speaking, Xu Jiu's eyes moved up and looked at a stalactite hanging at the top of the pool, and water droplets were dripping at its tip.

The ability to launch shock steps, raise your hand and attract a wind to cut off the soil layer on the surface of stalactite.

Sure enough, it began to show the same crystal columns as the crystal clusters between the rock walls on the road ahead.

"This may be a water taking place. We have come all the way and basically deliberately determined that there is no river nearby. The distance from the surface is doomed to make it impossible to carry out direct transportation. The way to take water from the surface is cut off, and the only thing we can rely on is the underground river."

Albert observed the surrounding environment, reached his own conclusion, paused, and then said,

"The water may come from an underground river somewhere in the valley. The evil energy spilled from the seal erodes the river, and the water flowing here will naturally be affected accordingly."

Xu Jiu didn't answer, but looked at Zhong Rushi and fell silent.

Xu Jiu has to admit that the water intake function mentioned by Albert may indeed be one of the reasons why people of relic civilization established here, but his intuition tells him that this is by no means the main reason!

In front of the pool, the stalactite on the top, plus the way of water storage

If it's just to get water, why make so many pools, not to mention the way of storing water bit by bit. Isn't it difficult to support yourself when you're full?

One more thing.

As the crystal pillar of the stalactite body, Xu Jiu knows the energy contained in it better than anyone. Even if it is extremely weak, he still senses the energy similar to the crystal of sage in the first piece just broken in the channel.

Even if the sage's crystal in his chest can't absorb the energy, Xu Jiu still realizes that before being eroded by evil energy, these water is not ordinary groundwater!

Across the monster's body, Xu Jiu's eyes wandered around the cave. He didn't think there were only these pools here. It was likely that there were other equipment, at least related to the inscriptions on the heart of the monster.

Facts have proved that Xu Jiu's guess is accurate.

When the members of the expedition leaned towards the depths of the grottoes, Xu Jiu, who was walking at the front end, saw the special platform in the area opposite to the front door when he came, the various instruments placed around it, and the operating table in the center

This is a laboratory left by the relic civilization!
