On the Feasibility of Making a Diving Suit with Koukaku

"Plop!"

A soft, muffled sound of water rose and fell, completely swallowed by the still turbulent seawater in Mao City.

The Shisui in the night sky now tightly folds its broad wings.

Like an arrow released from a bow, he plummeted from the sky at an astonishing speed.

His body tilted at a steep angle, like a bolt of Lightning speeding straight toward the waters near the Wunu River.

The moment it entered the water, the Ukaku on its back instantly spread out and then began to move like fish fins.

They adjusted their direction of movement, directing the Shisui towards the upper reaches of the Wunu River.

To increase his speed underwater, Shisui slowly released his Psychic Energy.

They draw upon external Psychic Energy to form a smooth, thin protective layer.

Although this temporary Psychic Energy membrane consumed a lot of energy, it was enough to prove one thing.

Given sufficient Psychic Energy, terrestrial creatures can also breathe, move, and even live underwater.

Shisui moved extremely fast, covering a kilometer in about ten seconds and leaving the saltwater environment.

Soaking in the clearer freshwater of the Wunu River, he did not stop immediately.

Instead, it maintains this speed, removes the protective layer, and swims for another ten seconds or so.

As it moved at high speed, the water flow washed over Shisui's body and the Steel Feathers Ukaku his back.

The river carried away all the sea salt and dust floating in the feathers.

Shisui broke through the water's surface, found a secluded riverbank close to the water, and with a push of his hands, flipped himself over and sat down on the bank.

He took out a crystal and gnawed on it to replenish his almost depleted psionic Psychic Energy.

He recalled the amount of energy his body had consumed before and after activating the protective shield.

For the first ten seconds, it moves at high speed in the water while maintaining Psychic Energy Shield.

The above amounts of Psychic Energy are minus the energy consumed during the high-speed movement without a shield for the last ten seconds.

The amount of energy required to maintain the Psychic Energy membrane can then be roughly estimated.

"Sigh, nearly 80% of the energy consumption comes from the shield."

Moreover, this protective shield is only in its normal operating state during underwater navigation.

He was worried that if they were fighting underwater, the Flesh Crystals he had just collected wouldn't be enough.

After all, the Dragon Palace is located in the Pacific Ocean outside of the Ringwater Continent, and to travel from Mao City by water, one still has to cross the Tianpiao Ocean.

This method, with its alarmingly high attrition rate, is something Shisui really doesn't want to use anymore unless absolutely necessary.

"Click click click..."

After finishing a crystal, his Psychic Energy was only about one-fifth full.

So he took out another one and started eating it while thinking.

The flow of Psychic Energy within the Kagune would greatly reduce energy loss.

I wonder how much energy it consumes to use Koukaku as a diving suit.

With a thought, the Koukaku extended, spread, and enveloped from behind until it completely covered Shisui's body.

The Rc Cells density of the Koukaku is the highest among all Kagune, making it much heavier than other Kagune.

One of the main reasons he grew a second pair of Ukaku was to ensure that his movement speed would not decrease in his Kakuja state.

With his innate Owl Wings alone, he couldn't even run while wearing the Koukaku Kakuja.

Not to mention, we're now heading to the seabed.

As long as the Koukaku itself isn't completely destroyed, it does consume very little energy.

However, it's hard to say whether lifting the Koukaku and moving it at high speed in the water consumes as little energy as usual.

As his Psychic Energy was gradually replenished, Shisui stopped and plunged back into the river.

With the buoyancy of the river and the support of Psychic Energy, the Koukaku Shisui swam smoothly.

The half-face mask made of Koukaku provides the air that Shisui needs to breathe.

As he moved, he began to thin the Koukaku, reducing its overall weight.

Let's try killing a couple of Sea Race in Mao City first.

He turned underwater and followed the flow of the Wunu River back to the submerged Mao City.

At this moment, Mao City is already a vast expanse of water.

Groups of Sea Race drove over some enormous sea beasts and began dismantling the underwater city buildings.

"Hurry up! You useless beast, you dawdle even when you're just trying to bump into something!"

The unique pronunciation of the Sea Race' common language is transmitted to their ears through the vibrations of the water.

The latter simply impacts buildings with reinforced steel interiors much faster.

Many marine mammals have had their tough skin scraped by broken steel bars, resulting in numerous scratches on their skin.

The Sea Race was still cursing and swearing.

The sea creatures he brought were to be responsible for an area near the Wunu River in Mao City.

Like him, there were many other ordinary Sea Race soldiers responsible for "clearing the area."

Each of them led several tough-skinned sea beasts, scattered throughout the former Mao City area.

Before dawn, they had to level all the buildings here and carve the Sea Race' unique runes into the ground.

Thus, even if the Human Race army arrived and fought with all its might to reclaim Mao City,

All that was left was a ruin submerged in water.

And those runes will keep the seawater in the vicinity from receding.

So that the ruling class of the Sea Race could effectively control the mouths of the two rivers.

Dawn is approaching, and the Sea Race responsible for drawing runes in the rear are being urged on by their superiors.

So they impatiently began urging the Sea Race ahead to flatten the city.

This led to those responsible for clearing the area becoming increasingly frustrated.

"Um?"

Just as he was directing the sea beasts to scatter and crash in different directions, the Sea Race vaguely sensed something.

The sea creatures moved away, while he remained where he was, sensing the flow and vibrations of the water.

Something's wrong! Someone's getting close!

Before he could dodge, a black figure crashed directly into him.

"Bang!"

The Sea Race only had time to turn its body and raise its hand to block before its ulna snapped with a "crack".

Then, the newcomer's fin-like limbs sliced through the seawater, aiming directly at the Sea Race's throat.

"No..."

Before a sound could be uttered, the head was thrown off.

The bright red color instantly blended with the seawater, and a strong, fishy smell spread.

Shisui dodged the gushing blood. At this moment, the Koukaku on his body was like a thin suit of armor, obediently covering his body.

With its speed remaining constant and energy consumption relatively low, and having sacrificed some of its defensive capabilities, the Koukaku can be fully utilized for underwater combat.

In the distance, the sea creatures, having caught the scent of blood, charged forward in a frenzy.

Roars echoed throughout the room.

Koukaku activated Spatial Energy, obscuring Shisui's figure.

He flapped his wings slightly and swam towards the open sea.
