"Are you saying that only those who have the key can enter this underwater city? ”

"Yes, young master. ”

Liu Long agreed with the speculation one by one, after all, under such a large atmospheric pressure, if there was no special means, there would be no way to enter the underwater city, because even if there was a hole as small as the eye of a needle, under the action of atmospheric pressure, the entire underwater city would be swallowed by the sea in an instant.

Although he knew that the way to let the big crab find to enter the underwater city would not work, Liu Long did not let the big crab stop looking, of course, there was no miracle in the result, after trying all the methods, the big crab stopped on the protective cover, because after searching, this protective shield was simply invulnerable and did not have any loopholes.

"One by one, think about whether there is any other way. ”

Looking at such an unknown underwater city, how could Liu Long not be tempted, but now the protective shield that protects the existence of this city has become an obstacle for him to enter the underwater city.

"Young Master, the only way now is to wait until our technology reaches this level, crack out the key, and then enter. Obviously, there was nothing to be done about it, so he said with some frustration.

After hearing Yiyi's words, Liu Long's mood suddenly became unbeautiful, but he also knew that since Yiyi said that there was no way, it was obvious that there was really no way.

But until the technology of space science and technology reaches this level, I don't know what about the Year of the Monkey, if it is discovered by other countries, it will be impossible to eat alone, so I asked one by one, "Is there a way to hide this place from other countries?" ”

"Young master, don't worry about the problem you said at all, although the depth of the sea here is nearly seven thousand meters, but with the current technology of the earth, if it can be discovered, I am afraid that it will be discovered, and it is impossible to wait for us to find out. ”

"What do you mean?"

"This area has been manipulated by man, and it can be said that any electronic device will fail when it reaches this sea area, and the closer you get to this underwater city, the more interference will be. ”

"At a depth of about three thousand meters, any electronic equipment will be damaged and lose its due value, the reason why we can be unimpeded is the credit of the magnetic field, but because the interference here is too strong, the power loss is also huge, if it is not for the fact that we are equipped with 10,000 times graphene batteries, I am afraid that it will not be able to support it for a long time. ”

"And there will be magnetic field vortices from time to time, maybe you didn't notice it, young master, there are many shipwrecks and planes on the side of the protective shield, if I guess correctly, I'm afraid they were all circled by the magnetic field vortex to the bottom of the sea when they passed through this sea area. Explain to Liu Long one by one.

Hearing the explanations one by one, Liu Long knew that his worries were superfluous, and at the same time understood why so many ships had mysteriously disappeared, but seeing the mysterious city close at hand, he couldn't enter, and Liu Long, who was a little depressed, controlled the big crab to vent the depression in his heart.

Under the control of Liu Long, the big crab dived to the bottom of the sea from the protective cover, and then controlled two large pincers, and the brush fired a laser.

Just when Liu Long was about to vent for a while and then return to the voyage, he suddenly stopped Liu Long one by one, to be precise, to tell Liu Long to stop controlling the big crab.

"What's wrong. Liu Long, who was suddenly stopped, asked one by one suspiciously.

"Young Master, maybe I have a way to enter the underwater city. One by one, he looked at the turbid seabed through the screen, and then said to Liu Long.

"Can you find the key. Hearing that he could enter the undersea city, Liu Long suddenly became interested.

"Whether it's the key or not, we'll find out in a moment. ”

After finishing speaking, he personally controlled a big crab to walk towards the turbid seabed, and then knocked on the turbid seabed, picked up a relatively small stone, and then groped on the stone for a long time, the stone was divided in half, like a box was opened, and what was contained inside was a thumb-sized colored "jade" drop pendant.

"One by one, is this the key to entering the underwater city. Liu Long looked at the colorful pendant in the hand of the big crab through the screen with some disbelief.

"Wouldn't you just have to give it a try? ”

As he spoke, he took the pendant in his hand and walked towards the protective shield, but the miracle did not happen, because the big crab did not enter the underwater city as he wished.

"It seems that we were rejoicing too soon. Seeing that the big crab did not enter the underwater city, Liu Long said with some disappointment.

After seeing the results one by one, he was also disappointed, but he had a feeling that told him that this was the key to entering the underwater city, but the way to enter was wrong.

Because this colorful drop pendant will not be placed here for no reason, but also put in the stone box, looking at this stone box that is integrated with the surrounding reef, there is reason to believe that this stone is the key to enter the underwater city, because it is very similar to our life, afraid of losing the key, so we hide the key in the flower pot at the door of the house.

So he controlled the big crabs one by one, trying various methods to enter the underwater city, but the results were all in vain.

"Young Master, you can be sure that this is the key to entering the underwater city, but why can't you enter it? "There is no doubt that this time I was stumped one by one.

"You're sure. Seeing that he couldn't enter the underwater city no matter what way, Liu Long had already given up on the fact that this was the key.

"Of course, haven't you noticed that hiding a droplet pendant in a stone box that is not easy to find is like a schoolboy who is afraid of losing the key and hiding it in a flower pot in front of his house. ”

After listening to Yiyi's words, Liu Long seemed to be empowered, yes, when he was in elementary school, just like Yiyi said, in order not to lose the key, he often hid the key in the flower pot, which is too similar to the hidden way of the water drop pendant in front of him.

Now that you've determined that this is the key, all that's left is how to use the key correctly, then find the lock, and open it.

"One by one, you try to hold the box in your hand with the pendant before entering the shield. ”

One by one, he controlled the big crabs and tried according to what Liu Long said, but he did not enter the underwater city as he wished.

Just after Liu Long and Yiyi tried various methods one by one, but to no avail, they even wondered if this was the key.

Liu Long, who was a little helpless, lay on the chair and prepared to take a few breaths of oxygen to relieve his mood, but when he picked up the oxygen mask, he suddenly slapped his thigh and yelled at one by one, I know how to open it.
