Before this dive, everyone adjusted their watches, they had to complete the exploration and return to the surface within an hour, their oxygen in the Blue Hole will be very huge. Pen & Fun & Pavilion www.biquge.info

At this point, Han Yu felt it as soon as he started diving, and a heavy pressure pressed against his chest, making him feel difficult to breathe all of a sudden, and he almost couldn't breathe.

It's like a big fat man sitting on his chest fiercely, Han Yu feels very uncomfortable, and when he looks at the others, it seems that he and Xu Ding's situation looks similar, Uncle Chen is better, and Master and Tian Yu are like swimming fish in the water, swimming freely.

Gritting his teeth, Han Yu turned over, rushed his head down, and dived for more than ten meters in a row, the surrounding light became dim, although everyone was equipped with an underwater strong flashlight, but Han Yu felt that he didn't need this thing.

Long before he entered the water, he blessed himself with the Luminous Charm, and when he dived into this depth, he was instantly stunned by the scenery in front of him.

Groups of brightly colored tropical fish surrounded him, and Han Yu couldn't help but run after them, and before he knew it, he was away from everyone.

Because at the bottom of the sea, due to the obstruction of light, they had no way to detect Han Yu's departure in time.

Han Yu swam all the way, and after inadvertently diverting his attention, he didn't feel tightness in his chest anymore, the more he swam, the more he swam, the more comfortable he became.

He has never used a diving device, usually going to the beach at home is at most snorkeling, and diving five meters is already a terrible thing, not to mention that now in this blue hole of Youlan, accompanied by beautiful sea creatures, Han Yu is simply comfortable leaving everything behind.

Swimming and swimming, he only found that there seemed to be some bright light coming from in front of him, Han Yu was already at the bottom of the fifty meters at this time, this glimmer of light made him feel extremely curious in an instant.

People are born with the habit of tending to the light, and Han Yu is the same, he swam towards the light, and when he arrived in front of the light, Han Yu was stunned.

This is a huge blister, I don't know what it is, maybe it's water, maybe it's gas, it sways with the flow of water that Han Yu is stirring, but it has no tendency to break or lift into the air, its surface exudes a glowing light, it should be the light source that Han Yu just saw and was attracted.

Curiously stretched out his finger and poked it, and it actually reached through the film of the blister, Han Yu was startled, and quickly pulled it back, although he didn't feel anything, but Han Yu still carefully checked his finger, but fortunately it was okay.

So...... Han Yu had the idea of wanting to go in and find out, but it was white, he couldn't see what was inside at all, and in the face of unknowable things, after hesitating for a while, Han Yu still planned to break in.

He stuck his head in with his eyes closed, he was still wearing an oxygen mask, it was a superfluous move, and after waiting for a while, he found that nothing had happened, so he stepped in boldly and disappeared into the bubble.

At the same time, his anchor point also disappeared from the rest of the people's watches.

After the whole body came in, Han Yu only felt that his body was heavy, and he had a feeling of stepping on land, Han Yu jumped tentatively, and sure enough, it fell to the ground again, without the feeling of floating in the water.

Isn't that amazing? Is there such a place in the deep sea? Han Yu said that he didn't understand, because it was the first time he had come to this kind of place.

Trying to remove the oxygen mask, Han Yu found that the air here could be smelled, and it was very fresh, with a sweet smell, and looked around carefully, Han Yu found that there was a small hole in front of him, and a faint wind blew out of it, which seemed to be just enough for a person to enter.

After a moment's hesitation, he decided to take off all the heavy equipment on his body, put on only a thick wetsuit to keep himself warm, and walked towards the cave.

After crawling down a narrow aisle, Han Yu came to a slightly wide place, like a small room, and he was surprised to find that there were traces of artificial excavation here.

Looking up at the top of the cave, Han Yu walked, stepping on a hard thing under his feet, and when he looked down, he was shocked that his scalp was numb.

"Dead ...... Dead man's bones! Han Yu exclaimed in surprise, echoing in the empty cave room, he jumped back a big step, kept shaking at the corpse that had turned into bones, and apologized: "I'm sorry! The juniors didn't step on you on purpose, you have a lot of adults, just forgive the juniors this time! I'm sorry, I'm sorry! ”

The attitude was extremely pious, and after a while, perhaps the fear in his heart slowly calmed down, Han Yu was no longer trembling with fear, but looked at the skeleton in front of him curiously, only to see that although his body was corroded to the point that only white bones remained, the clothes on his body were still intact.

Han Yu looked to the side, there was a cowhide book on the cuff of the bones, and there seemed to be a round one on the book, I don't know what it was.

Han Yu stepped forward cautiously, and after confessing his guilt, he took the book, took a few steps back, and looked at it carefully.

First of all, on the cowhide book, is a pendant, I don't know what material is carved from, but look at the feel, what kind of jade should be, but the strange thing is that it is black throughout.

Of course, Han Yu didn't understand this, he only thought that the jade pendant was very good-looking, thinking that it was already an ownerless thing, so he didn't care about accepting it.

Carefully opening the brown paper book, Han Yu found that it was written in Chinese characters, but it was in traditional Chinese, because he had not learned it, Han Yu could only understand individual words, and even guessed with confusion, feeling that it was like a diary.

In the deep sea, there was a cave in a mysterious water bubble, and in this cave, there were even ancestors who came, which made Han Yu unable to understand what the connection between this person and this cave was.

Skipping the introduction, Han Yu opened the first one, only to see that it read: "Unknown weather today, unknown date." I have been trapped here for a few days, drinking the sweet spring on the top of the cave every day, eating the algae at the bottom of the sea, for the sake of ............, I don't know when I will die, fortunately, the ............ with me, record...... In this uninhabited space, if anyone picks it up, please bury my body and give it to it with ink jade. ”

There was so much writing on the first page, Han Yu could not understand much, plus some of the handwriting was already blurred, he had a hard time reading it, and when he turned to the next page, Han Yu only felt a cool breath rising from the soles of his feet.
