After getting down for more than one hour, he estimated that he is more than 1500 meters deep and Sam found a rocky terrain on the sea bed.

He moved towards it and the place filled with rotten carcasses, some of them are of water bound creatures and some of them are of humans, there are a lot of carcasses.

Even the bones are corroded so much due to the toxins.

Sam went deeper and deeper into the rocky terrain and he only stopped when he found something weird.

There was a large area with some concentrated energy and when he used his observation, he wasn't able to understand what it realty is.

But when he moved towards it, he was able to sense that energy is distributed in that particular area and it is making all the water repel from it.

The pressure on him increased when he moved towards it and he has to increase the thrust so much to go against it.

If not for the fact that his body is physically as strong as a beast at the same level, he would have had his bones crushed under his pressure.

He not only found that formation is quite high grade, but it is very much eroded completely, as if the energy source is completely depleted.

Sam drifted towards the formation, but he wasn't able to enter easily.

The formation is completely sealed and even though there are some loop holes, Sam wasn't able to pin point them.

The loop holes are small and sparse and didn't appear all the time, so he waited as he swam around the formation to find out if there is any way to go through it.

After a long struggle, he finally found a loop hole in the formation and slipped into it.

*splash*

The water level inside the formation is strangely not full. Sam fell into the knee-deep water as soon as he entered. At this moment, even his suit started having corrosive problems and he immediately took out his hoverboard and started floating.

Inside the formation it seemed like a room with hemispherical dome. It completely deterred the water from entering inside and even the knee-deep water also came inside due to small loop holes appearing for split seconds.

But Sam's concentration isn't on the dome or the water, but on the skeleton right before him. The skeleton so massive that is not even as long as its claw.

Sam felt so in significant in front of the skeleton, but the massive size isn't the reason. The reason is the powerful aura that is coming out of the skeletal remains. Even though, it is not giving him enough pressure to buckle him.

He is still feeling insignificant. His bloodlines of Sky sovereign roc and Golden sun crow activated subconsciously to repel the pressure and then only he felt relief.

There are nine snake like heads to the massive figure, hind legs like dog and talons for front limbs, a d body like a hound, and tail like a dragon.

The bones have slight hint of purple on it. The skeleton is so majestic even in this state.

"Hydra." Sam could only mutter this word subconsciously.

Yes, the skeleton in front of him belongs to the mythical beast Hydra, but the hydra isn't completely same as that of Greek mythology of earth.

The on in the Greek mythology is Lernaean Hydra and that is only one in the world which is killed by Hercules.

The hydra in front of him are descendants of that immortal beast.

Sam let out Yanwu and Sky from the divine dimension. The formation provided him enough space to fly.

"Imprisoned Variant Hydra." Yanwu immediately muttered after seeing the skeleton.

Obviously, Sky didn't know about it at all.

Sam looked at Yanwu with a questioning gaze and the latter explained.

"Back at home, the story of this hydra is part of history. The basic hydra having nine heads will have same abilities to all his heads but the variant hydra is not same. Each head has different type of poison and each has different ability.

The hydra tribe ostracised these variant hydras from them due to their powerful abilities and eliminated them, but the story is that a normal male hydra from royal family and a female variant hydra escaped together.

But the whole tribe sent the power houses and even sought help from other tribes and chased them. Even though, the male is a prince and one of the strongest from the tribe, he was completely surrounded.

Since, he was from the royal family he was subdued and taken back to the tribe, while the female variant hydra was chased.

Then only they knew one thing, that the female is stronger than the male and even when surrounded by them, they were only able to subdue her and the instant kill was completely out of question.

So, they subdued her and imprisoned her in a very powerful formation, and the energy source is the beast itself.

In this way they left her to die after continuous depletion of energy. I never thought that I would encounter the imprisoned hydra here."

When Yanwu finished the story, Sam looked at the skeleton again and saw that there are some long chains attached to spikes.

Each long chain had one spike on end which was inside the skeleton, meaning it was stabbed to the beast core and the other end of the chain is connected to another spike which is stood like a pillar.

In the same way, there are lot of chains and spikes which are acting like the energy nodes and the source of energy.

The chains and spikes are full of runes. Sam closed moved towards the skeleton. The water is almost purple in colour, the concentration of the toxins is quite high.

He though of something and started immediately entered the divine dimension. He made a clearing in the water zone and created a formation.

He came out and started observing all the water to the divine dimension, this would not only help him to explore this place, he can also use this water to make some potent poison.

A pool was formed inside the dimension within the formation.

Soon, the formation became empty, but there is some water seeping slowly from outside, but it is not enough to fill the formation completely.

But when the water is completely empty, Sam took a step back in astonishment.

There is a huge egg in front of him which was placed horizontally, he wasn't able to find out earlier because the water level near the skeleton is high and the egg was completely submerged.

The egg is full of runes. Which seemed to be written with purple blood.

Sam didn't move forward and just probed it with his spiritual sense. A voice rung in his head.

[Whoever you are, I don't know you. But you are the only person I can ask you help now. I was chased by my kin and was separated from my love. The only thing I was left with was my own offspring.

If you are hearing this, my offspring is still sealed from birth and still alive.

But I don't know how many days the remnants of my energy will be able to save it for.

So, I hope you will unseal it and let it come to this world.]

Then the process of unsealing was transmitted to Sam's mind.

[I know that I don't have any right to ask for help. But I am not asking you as a beast, but as a mother.

My only sin is to be born as a variant and my child has nothing to do with it. I hope you can give my child a chance to live and you can have my remains as compensation.

My remains no matter how old they might be, are one of the valuable treasures in the world. Even the single claw or the fang can be made into a powerful weapon. So, I hope it is enough for you.]

This is the last message that came to Sam's mind before a glow disappeared from egg. But the runic seals which seemed to be from the blood of the hydra itself still remained. Apparently, they are runes that maintained the seal.

Sam looked at the formation which is still working, there are no restrictions on the egg though. So, he first stored inside the divine dimension.

So, after that he thought of the way to remove the restrictions of the formation to take away the skeleton.

Because, he wasn't able to move the skeleton and it seems that the chains are restricting the spatial transfer as he failed to move it into the divine dimension.

This only makes sense, as a top-level beast from the higher realms, the hydra might even be able to tear open the space, if there were no restrictions placed on it. He started his brain storming as he observed the formation and the spikes responsible for maintaining it.
