There are many kinds of caves in this world, caves on the mountains (caves), caves on the ground (crypts), caves in the universe (black holes), people's bodies... Ahem, so it's not surprising that there's a cave at the bottom of the sea.

But it's a bit strange to trigger the rare quest, the sea monster just now is a rare level, if it hadn't just attracted a lightning strike and hit it hard, it is estimated that even if the sea monster floats there for me to kill, it will take several days to kill it.

And if I meet it at the bottom of the sea, then I guess I'm dead.

Wei Shu drove the boat to the point where Bai Guang appeared, then dismantled the rod of the ox and tied the thick and long fishing line to himself, and the other end to the bow of the boat, and then he jumped into the sea.

Because of the heavy rain, the sea was very noisy, and it was a violent wind and a torrential rain, and almost all of his ears were the sound of wind and rain, but when he dived to the bottom of the sea, the sound of the rainstorm suddenly disappeared, and the surroundings suddenly became quiet.

At this moment, the sun has set, and the sky is covered by dark clouds, neither starlight nor moonlight can fall, so it is completely dark under the surface of the sea, and the only light source is the faint white light of the seabed.

There seemed to be something hidden in the darkness, and some strange sounds came up from under the deep sea, but with the "Shadow Blade", Wei Shu still had the courage to dive down.

Wei Shu kept diving, and occasionally he could ask about a fishy smell, this was because there were too many dead fish nearby, and the sea water was not cold, it was because he had just received the huge heat of the thunder, but the sea water was constantly cooling.

This time, Wei Shu sneaked down not to complete that task, but to observe what was going on with that bright light, he was not fully prepared, and came down just to reconnoitre.

Wei Shu kept diving, until he couldn't hold his breath and still didn't reach the bottom of the sea, because it was too dark around, Wei Shu couldn't see how far he was from the bottom of the sea, he could only rely on his feelings, but after diving for a long time, the soles of his feet did not touch the earth or stones.

He had no choice but to float, because he couldn't hold his breath anymore and he had to return to the surface.

As soon as he returned to the sea, the majestic rain hit his head, and the whole world was filled with the sound of torrential rain, as if a sudden noise woke you up, and the whole person could be startled.

Wei Shu swam back to the boat, this time he had to make some preparations, such as preparing an air bag, preparing a longer rope, the air bag is very easy to make, you can use the fish bubble, and the longer rope is so that Wei Shu can keep in touch with his ship, otherwise when he returns from the expedition, the boat will be gone, wouldn't it be very embarrassing.

The next day, the sun rose, and as far as the eye could see, the sky was cloudless.

Wei Shu immediately felt very happy, it was a good weather for exploration.

But it wasn't until Wei Shu dived underwater that he found out. The sun is so bright during the day that you can't see the light on the sea.

Your sister, this weather is not good, it is not suitable for underwater exploration at all.

However, Wei Shu has already made a mark on the ship, as long as he follows this mark...

Do you think the story of carving a boat for a sword is really just a fable? Do you think that the purpose of carving the boat for the sword is to illustrate the need to look at things from the perspective of development?

I'm so sorry... Really.

Wei Shu dived down to the location of the mark, but found nothing.

This is normal, it rained all night, the position of the ship has long been offset, it is definitely not in the original position, the truth of carving the boat and seeking the sword has long told us that we must look at things from the perspective of development.

And Wei Shu just tried it, after all, he had no other way to determine the location of the submarine cave.

It seems that we will have to wait until the evening to dive again.

Wei Shu prepared for a day, and waited until the evening, tonight the sea was calm, there were many clouds in the sky, but there was no sign of rain, the sea was pitch black, Wei Shu jumped out of the boat, fell into the sea, and then began to dive vertically.

He dives very quickly, due to his high cell density, which looks about the size of a normal teenager, but his mass is far greater than that of a human, which causes him to dive very fast, and it takes more effort to ascend.

However, because of his strong physical fitness, he was able to hold his breath for a long time under the surface of the sea, and with an air bag, he was able to search the underwater cave for a longer time.

Wei Shu slowly dived, and it didn't take long for him to see a little white light source.

Got it.

Wei Shu immediately swam in the direction of the light source, and it was not until the bottom of the sea that Wei Shu saw a particularly hidden cave, from which that little white light emanated.

Wei Shu dived down and saw a huge hole with a diameter of fifteen meters, and he saw a huge pit near here, which was obviously the habitat of the previous behemoth.

Treasures must be guarded by fierce beasts, which is the routine of traditional Xianxia online texts.

But everyone else kills beasts for the sake of treasure, and I killed the beasts first before I came to hunt for treasure.

Wei Shu pointed the mouth of the air bag at his mouth and took a sip, the air bag was made of fish bubbles, and it was also covered with a layer of animal fur for protection, but the air bubbles in the air bag did not smell very good, and after inhaling into the mouth, he immediately felt a fishy smell on his tongue.

But Wei Shu couldn't care about it so much, he spat out a bunch of bubbles, and then got into the huge hole.

Wei Shu paused, ready to explore this cave under the sea, after all, the caves where good things are hidden are very dangerous.

As a result, Wei Shu saw a wall.

Wei Shu: "..."

What about the caves? Why do you come in and see that it's a wall?

There was a small gem in the middle of the wall, which emitted a white glow, which looked very faint from a distance, and when I got closer, I felt that this gem was very bright.

What kind of treasure is this gem?

Wei Shu began to buckle the gem, but he couldn't buckle it, the gem was set too tightly, and then Wei Shu took out the hunting knife again, and then used the hunting knife to pry, but he couldn't pry it out.

Wei Shu was busy for a long time, but he still couldn't pry the gem, I don't know what material the wall was made of, it was very hard.

Wei Shu was suddenly a little discouraged, this is not a gain!

Then Wei Wei saw a string of small characters on that wall, and it was also in Chinese.

Wei Shu: "..."

The small words are four words: "Open the door with blood".

Wei Shu: "..."

It's dark under the lamp, it's dark under the lamp, and the first thing people think of when they see the wall is how to open it, why do I first think of taking this gem off?

People are really different.

The gem turned out to be a lock.

Wei Shu suddenly remembered, this Nima is a game, which player will deduct the gem on the door in the game copy?

Wei was supported, but he still didn't adapt to the current rhythm.

Wei Shu stretched out his finger, and then cut it on his finger with a hunting knife, and the blood suddenly spurted out and scattered with the sea.

Wei Shu suddenly felt that this hunting knife was awesome, his skin was so tough, this hunting knife was actually cut with a single click, could I have ignored some artifact?

Wei Xu's blood had already flowed onto the gem.

Immediately after, the gem emitted an intense white light!
