Starting from the ultimate, the keeper behind the Nine Gates

Since we set off relatively early, after all the preparations were completed, the sun had just emerged from the horizon.

The gushing sunlight dissipated some of last night's chill.

But the water in the pool is still bitingly cold.

Fortunately, the dry diving suits worn by everyone blocked most of the cold for them, preventing them from losing body temperature.

At first, the space in the reservoir was not very generous, and several people were somewhat constrained in their diving movements.

The oxygen tank behind him would hit the stone wall from time to time.

But when we reached about ten meters underwater, it suddenly became clear!

They seemed to have suddenly fallen into a different world without boundaries.

The darkness swallowed them up instantly, and the surroundings became even more terrifyingly quiet.

Everyone stopped in unison and let their bodies hang vertically in the water.

At this time, they could only hear their own heavy breathing.

His vision and hearing were both blocked, and a strong sense of suffocation came over him instantly!

Unable to see, several people turned on the search lights above their heads one after another.

The beams of light intertwined together, like three cold knives cutting through the thick black curtain.

Let everyone finally see each other clearly.

But that's all.

The range of the overhead searchlight was limited, and it was still pitch black in the distance.

Unable to speak, Wu Sanxing swam to the middle and made a few gestures to follow him.

Everyone then continued to dive.

With limited oxygen, they must hurry up as much as possible.

It wasn't until we dived another hundred meters or so that the bottom of the reservoir gradually appeared in front of everyone.

It is about the size of a football field and is circular in shape.

A bronze chiki with a dragon's head and a fish body is glaring at the beast's eyes as big as a copper bell, guarding the center with an open mouth.

Chiki is the legendary ninth son of the dragon. It has a big mouth and belly that can hold a lot of water. It is often used as a water-controlling mythical beast.

It matches this small belly and big reservoir very well!

There are dozens of passage openings on the rock walls around the bottom, all of the same size and shape.

One of these pathways is where they want to find their target.

So in order to save time, the eight people spread out in groups of two to search.

Wu Sanxing had said it long before they came down.

The reason why he was able to find Stone City so quickly was because of the marks left by his little brother back then.

If nothing else, there should be one here.

It's just that the little brother himself has lost his memory and can't remember the location at all, so they still need to search carefully.

Jiang Xing and A Ning chose a direction and swam there.

Since everyone else is sharing an oxygen bottle and cannot move separately, they can only check together inside and outside the channel.

In comparison, they are relatively free.

Soon they came to a passage, and A Ning motioned to Jiang Xing for her to go in and check.

When he was about to swim in, he was stopped by Jiang Xing who raised his hand.

Facing A Ning's confused gaze, Jiang Xing silently pointed to the ground beneath them, and then shook his head.

Ah Ning didn't understand its meaning at first, but she realized it after reading it twice.

Some of the silt at the bottom of the pool rushed into the channel, ranging from thick to thin.

Explain that this channel is the drainage outlet that drains water from the reservoir.

If the drainage from the tomb chamber enters the pool, the ground in the passage and even the ground around the entrance cannot be said to be free of silt, but it can also be seen that it is much thinner than other places.

Through this method of observation, they can eliminate part of the passage even if they don't have to go in.

But by the time she came to her senses, Jiang Xing had already swam far away.

Ah Ning was so busy that she chased after him. After determining that it was the channel that conveyed water from the inside to the pool, she and Jiang Xing checked it separately.

So the speed is faster again.

On the other side, Wu Tianzhen also discovered this method after searching for a few more passages.

After only a few practical operations, I found that familiar string of marks in the passage.

The reason why he was familiar with it was because he had seen it in the tombs he had visited a few times before, so he saw it almost at a glance.

Wu Tianzhen's eyes lit up instantly, and he gestured excitedly to the boy next to him.

Seeing this, the little brother also curled up his lips in a subtle way.

The two men immediately swam out of the passage and used the searchlights above their heads to signal others.

But as soon as he pressed it, a figure suddenly appeared in the passage next to him!

Wu Tianzhen, who was immersed in joy, was startled and even bumped into the little brother behind him.

After taking a closer look, I realized it was Jiang Xing.

The expression on his face changed from frightened to relaxed, but then suddenly turned to shock as he looked up.

You must know that they and Jiang Xing searched from both sides towards the middle.

Although they will eventually converge, their speed is too fast.

He just found the trick, and the search was less than half...

Jiang Xing was quite speechless as he looked at Wu Tianzhen, who was shocked and changed his expression in front of him.

The light from the searchlight above his head is so obvious, how can he be scared?

Do not understand.

Jiang Xing looked away without even noticing, and turned to look at the little brother behind Wu Tianzhen.

Use your eyes to ask if they have found the passage into the tomb.

Jiang Xing obviously showed no movement, expression or eyes, but the little brother somehow understood what he meant.

So he nodded slightly, indicating that he was here.

Wu Tianzhen, who was caught in the middle and ignored: "..."

Damn it, the communication methods of patients with the syndrome are really advanced.

Brainwaves send messages!

After a while he sent the signal again.

At this time, Ah Ning also swam out from another passage.

The searchlight above Wu Tianzhen kept flashing, and he soon received a response from Fatty Wang.

And his third uncle seemed to have just entered the new passage, and after a while he saw faint light coming through.

Next, we just need to wait for them to come out and join together.

But right now!

The little brother suddenly grabbed him and swam towards the passage behind him at high speed.

Jiang Xing also followed closely with An Ning.

When Wu Tianzhen came to his senses, others were already in the passage.

But he didn't need to explain, he felt that the water outside the channel started to flow.

And still in different directions!

It's obvious that the reservoir is draining outward!

Wu Tianzhen hurriedly looked in the direction of Fatty Wang and his third uncle.

But the fast-flowing water stirred up silt on the ground, reducing visibility.

You can only vaguely see a beam of light that is constantly turning.

This means someone is in the rapids!

Wu Tianzhen's heart suddenly rose.

He just vaguely saw bright light coming from the passage where Uncle San and Black Glasses were, they might not have come out yet.

It would be okay if the channel they were in drained away from the pool, at least it would be safe.

But if not, it’s even more dangerous!

They are now under more than [-] meters of water, and the impact of the water pressure from opening the drain is enough to kill someone.

There was also Fatty, who was already heading towards them just now.

He seriously doubted that the light was one of Fatty or Mop.

But don't worry!

Wu Tianzhen's face was pale at this time. He was so flustered that he couldn't help but clenched his fist and hammered the stone wall hard, trying to relieve himself.

Upon seeing this, the little brother immediately put the respirator on him.
