Test… test… I remember that I have to do a test…

But what test???

"Leon, Leon! Are you okay?"

Leon was shocked and woke up from his thoughts. He saw the big, black hand he remembered so well. A large man with black skin that exudes African characteristics, his body is quite stocky with a height of around 190 cm. Leon immediately remembered this friend.

"Johnny, you don't need to move my body like that. I'm fine."

"Are you sure? I just want to remind you one last time. "We will dive at a depth of 100 meters below sea level, exploring underwater caves with an oxygen cylinder that can only last for 6 hours."

"I told you, I still remember it. Do you still doubt the memories I have?"

John didn't comment anything further. He went outside to start getting ready and put on his diving suit. Leon looked outside, there was only the vast blue ocean in front of him.

They are currently on a large yacht owned by John. Leon was already wearing the diving suit that John provided and was ready with everything he needed. What he was waiting for now was for John and the others to prepare.

"Strange, I seem to have forgotten something very important." Leon frowned and looked at his reflection on the calm ocean in front of him.

The horrible and disgusting feeling of forgetting something was truly the first time he had felt this way. Leon has what doctors call perfect memory.

A talent that he considers a curse in his life.

This is a genetic disorder that appears for the first time in this world. At least what is recorded in medical and biological history. Different from the form of Eiditic Memory, Perfect memory can be said to be something truly superior.

Not only can he replicate images perfectly, but he can remember everything captured by his five senses as if he were seeing his own reflection. Leon once tried how strange this thing called Perfect Memory was and stayed in the library while reading everything there.

As a result, Leon could remember all the books there just by reading them once. He could explain even the smallest details of the book in just one look.

That's just the smallest aspect. What made him say that this was a curse was the influence brought by this Perfect memory.

Everything seemed interesting at first, but after he tried it for the first time, the feeling disappeared and was replaced by something bland. Be it games, food, and even feelings. It's all fun at first but gets boring later.

He could remember clearly and there was no need to do it a second time. Because of this, Leon really hates things that are stagnant and unchanging.

"I have never forgotten anything in my life. Even if it's the tiniest memory." Leon looked at his face reflected in the mirror. All kinds of memories from the smallest start to appear as if showing a long video from small to large.

It was quite short when Leon finished remembering all the memories he had.

"There is no irregularity at all. Everything is the same and nothing is strange." Leon tapped the edge of the ship at a slow tempo.

Love this novel? Read it on Royal Road to ensure the author gets credit.

He was sure that nothing had changed, but he was very sure that he was forgetting something.

"Leon, are you ready?" Johny called Leon and woke him up from his reverie.

"I am ready." Leon got up and immediately followed Johny and the others. They put on gas masks connected to oxygen cylinders and began diving.

The beautiful underwater scenery amazes divers but not Leon. This isn't his first time here. In fact, this is where Johhny taught him to dive.

Johhny started giving signals for them to start diving deeper. Leon and the others immediately followed Johhny and went to the cave they were going to.

Immediately, they turned on the flashlights they had and used them as the only light they had. In an instant, there was only darkness around them.

Inside this cave, no light could enter so there was only complete darkness in this place.

Leon felt the feeling he always felt when experiencing something new for the first time. A dark cave with something unknown inside, and who knows what he would encounter, Leon immediately became excited.

Leon and the others were holding on to the guiding thread that they could use to get out of this place. The only thing that can guide them is to get out of this underwater cave.

What are they really looking for here?

Nothing. Johny suggested going to this place because he felt that this was an extreme activity that could bring adrenaline to its peak. Those who agreed to take part were people who lived with a sense of danger and a high adrenaline rush.

Without such feelings, there is no point in living.

Don't people always say that you only have one life?

If so, then I choose to live like Larry.

John even shouted such words the day Leon asked him to teach him to dive.

Leon calculated that they had been here for about an hour. He had seen many things in this underwater cave.

Several fish and other aquatic species, coral, and various kinds of stalactites decorate this cave. Leon was at the back of the line when something caught his attention.

"That… What is that?" He turned his head to see a rock that was quite far from where they started. Without thinking, Leon removed his hand from the rope he was using and swam away.

His eyes seemed to shine when he saw a unique coral that he had never seen before.

What does it mean?

That meant that Leon was the first person to discover this species of coral. Leon slowly tried to touch the coral in front of him. The color is quite blurry because it lives in places where there is no light. But Leon didn't care.

After observing the Coral for a while, Leon lost interest and looked back.

"Oh Shit. I'm really in trouble this time." Leon almost wanted to curse himself when he saw the empty darkness in front of him. Even with the light provided by the flashlight he had, Leon couldn't see anything.

"I really hate myself."

***

How long?

Maybe 3 hours? No, 4 hours?

"Right, I'm sure that I've been here for 4 hours. The time I have will soon run out."

Leon sat in a small room in the cave. His chest felt a terrible tightness and he needed to breathe with the oxygen tube he was carrying.

"I have to look for another place, the oxygen in this place is starting to run out." Leon started putting on his oxygen mask and started diving again. In this dark place. He gave John many instructions, according to what they agreed.

Leon saw the red Flares that he scattered in various places. The flare light had been burning for several hours and was slowly starting to dim. Leon didn't dare move from his spot for now.

What if John and the others came to this place when Leon decided to leave?

That thought always haunted him as he spread another Flare every 30 minutes.

"This is the last one." Leon tightly grasped the Flare that was emitting red light and threw it towards the bottom.

After throwing it, he returned to the small space from before. This was the only place that could let him rest. Leon sat back and looked up at the colorless cave ceiling.

"Strange, for some reason I always feel like I'm forgetting something important."

Something so important.

"Cough..." Leon felt a gasp that made him unable to breathe. He immediately took the oxygen mask and inhaled quickly. His body trembled and slowly became relieved.

"John, come quickly. I don't have much time left."

There is not much oxygen left in this tube. I don't even know how long I can last.

No, would he perhaps come? It's been hours since I disappeared.

Correct. It's been hours. With the nature that John has, he will check on the people who are taking part every 20 minutes.

"This is strange. Really strange." Leon slowly got up and stood while holding the oxygen cylinder in his hand.

He's been here for 4 hours. 4 hours in fear of death that always loomed over him.

"No, that doesn't matter anymore. I can't go on like this."
