Chapter 567 The Key Hole
This time, Zhuang Xin looked at the gate of the Kingdom of the Sea, which was nearly ten meters high and five meters wide, swimming slowly, carefully looking for the keyhole.

At the same time, he took a look at the stone key in his hand. Judging from the size of the stone key in his hand, the keyhole on the gate of the sea kingdom should not be too small.

But right now, he didn't find anything, not to mention the key hole, he didn't even find a hole in the gate.

Zhuang Xin was in the water, looking at the gate of the sea kingdom in front of him, he couldn't help but feel puzzled.

After thinking for a while, Zhuang Xin suddenly had a flash of inspiration.

The Kingdom of the Sea is a country built on the sea, and it relies on the U-shaped loop in this sea area. The sinking of the Kingdom of the Sea suppresses one end of the U-shaped loop.

And the key in his hand is the key to open the door to the kingdom of the sea, and another meaning is the key to make the kingdom of the sea reappear in the world.

The entire country of the sea has its own buoyancy device drainage system, and the reason why it sank below the water surface was all because of a sudden tsunami.

As a result, the buoyancy device drainage system of the sea country itself was closed for some reason, and the key in Zhuang Xin's hand was the key to open it.

Therefore, the key in his hand is not meant to open the door of the Kingdom of the Sea in front of Zhuang Xin, but refers to something else.

After thinking of this key point, Zhuang Xin couldn't help swimming directly through the flashing gate in front of him and entered the ruins of the kingdom of the sea.

Nightingale and others on the water and everyone in the three tribes were looking forward to it, but there was no movement for a long time, and the excitement slowly turned into worry again.

"Brother Zhuang, he must have encountered something dangerous again?" Aotian couldn't help guessing.

Chi Lian frowned slightly and said: "You crow's mouth, it's better to say a few words less!"

After being told by Aotian, although everyone is unwilling to think about it, they still can't control their minds to think about it.

Nightingale couldn't help looking at Sha Hai, Kang Rui, and Ron.

"Aside from the big snake, are there any other dangers?" Nightingale looked at Sha Hai, Ron, and Kang Rui and asked.

Sha Hai, Kang Rui, and Ron also looked worried at this time. After all, it is about whether the Kingdom of the Sea can reappear in the world, and whether they can communicate with the outside world!
After Nightingale asked, Sha Hai, Kang Rui, and Ron couldn't help showing thoughtful expressions at this moment, and they didn't think that there would be other dangers.

The answer given by the three people shook their heads.

"There should only be those big snakes." Sha Hai looked at Nightingale and said, "And those big snakes have been dealt with right now, so could there be another hidden one?"

"That should be impossible." Sirius denied, "I think brother Zhuang should be exploring the ruins of the kingdom of the sea."

"Besides the big snake, there should be no other threats." The poisonous scorpion also said immediately, "The big snake is already the overlord here, and there should be no other dangerous creatures in their territory."

"What the poisonous scorpion said makes sense." Fengweihua continued, "Maybe we are just overthinking, it's the same as before. Let's wait for brother Zhuang to bring us good news!"

Speaking of these words of self-comfort, in fact, the worry about Zhuang Xin's safety in his heart did not decrease much.

At this moment, Zhuang Xin, who was in the ruins of the underwater kingdom of the sea, was visiting some areas of the kingdom of the sea, and was shocked by the ruins in front of him.

The ruins of the kingdom of the sea sank to the bottom of the sea because of a fight, and those buildings were well preserved.However, no bones or corpses were seen.

After thinking about it, there are those big snakes here, and the bones and corpses may have already become their stomachs.

No wonder those big snakes can grow so big.

After swimming around in some areas, Zhuang Xin came back to his senses immediately. What he has to do now is to find and reopen the buoyancy device system of the Kingdom of the Sea as soon as possible.

Use the key in your hand to turn it on again, so that the kingdom of the sea can reappear in the world.

After searching everywhere, I don't know when I will be able to find the keyhole. After thinking for a while, Zhuang Xin's eyes could not help but return to the gate of the kingdom of the sea.

His eyes fell on the city wall at the gate of the kingdom of the sea, wondering if he would be at a certain position on the city wall, and swam over involuntarily.

Thinking that the place to open the buoyancy device system should not be outside the gate, but somewhere inside the gate.

First, after searching carefully at the inner gate, it was still the same as before, nothing was found, not even a hole.

Zhuang Xin couldn't help but began to search for the keyhole along the city wall. Due to the relatively large area of ​​the city wall, Zhuang Xin could only search slowly, and his oxygen was constantly being consumed.

All of a sudden, Zhuang Xin's eyes fell on a certain part of the city wall, and he saw a relief picture of a circular simple pattern engraved on the outer surface of the city in front of him.

It can't help but look a little strange, the relief picture with circular and simple patterns in front of you looks like a piece of land covered with a swimming ring in the sea.

Seeing this, Zhuang Xin couldn't help being delighted. The relief picture in front of him depicts the image of the kingdom of the sea.

Zhuang Xin began to grope on the relief map. At this moment, he had a strong feeling that the keyhole he was looking for might be able to give him the answer in this relief map in front of him.

Everyone in the three tribes including Shahai on the water, Ron, and Kang Rui, felt like they were living every minute while they were waiting.

Moreover, Zhuang Xin has been going down for a long time now, but until now there is no movement at all. At the same time, several people can't help but are very worried about Zhuang Xin.

After all, such a long time has passed without any movement, and Zhuang Xin has never been out of the water.It feels like nothing has sunk into the sea, which makes people worry endlessly.

"It's been so long, why hasn't there been any movement?" Ghost Mandrill couldn't help but said, "This is really worrying!"

"Could something really happen?" Aotian looked at Nightingale and asked, "Why don't we go into the water and have a look? Wait here, I always feel uneasy in my heart, up and down of."

Nightingale shook her head and said, "The oxygen tank he brought is enough for him to stay in the water for more than an hour. Wait and see, if there is still no movement, we will go down and look for it."
