The Mighty Dragons Are Dead

In addition to Marquis Fugitive - Viswinti, who worked at the Overmarine Laboratory, and Salty Sea Marquis - Bluposi, who was constructing an overmarine city at the mouth of the Whirlpool River, the remaining five mermaids all dived into the ocean with Liszt, heading for the Undersea Sanctuary – Ach was focusing on researching the devil, so he did not join them.

The location of the Undersea Sanctuary was in the Shell Sea, situated between the Flame Islands and the Third Archipelago.

The mermaids' swimming speed was not slow, and a few hours later, they successfully reached the Undersea Sanctuary. The water depth was approximately eight hundred meters, and the light was somewhat dim, but the sanctuary resembled a massive crystal dome, enveloping an underwater region and shimmering with a faint rainbow glow.

Eternia stopped in front of the dome, "It's right here, Your Majesty, this dome is nothing special, just an ordinary bubble. But there is a weird power that keeps the seawater out. I tried to squeeze the seawater in, but I couldn't get it into the dome."

"Have you been into the Undersea Sanctuary, Eternia?" asked Marquis Fisherman - Gulvig.

"I haven't gone deep; I only walked a short distance along the edge of the sanctuary near the seabed... Walking with a fish tail is really troublesome."

Mermaids have noses and gills behind their ears, allowing them to breathe underwater or in the air.

However, mermaids do not have legs and can only bounce along on their tails, which is not only slow but also causes severe wear, so mermaids almost never go ashore. In this respect, the sea serpents have a great advantage; they and the mermaids are both darlings of the ocean, the mermaids are powerful, but sea serpents can go ashore.

"You wait outside; I'll go take a look," Liszt said, with a blue bone dragon totem on his face and a fire dragon totem on his chest.

After leaving the vast sea, his strength was bound to return to its peak, and he himself could transform into a phoenix, unafraid whether the sanctuary harbored danger or not.

He stepped forward, squeezing into the sanctuary through the water.

Instantly, he was greeted by a slightly moist, fragrant air, somewhat like the smell of a primeval forest, yet the environment here was completely different from a primeval forest or, indeed, from land. There were no green plants, only various glowing strange plants.

There were green ones, yellow ones, blue ones, red ones, multicolored.

Only a very few plants were non-luminous.

"These are some primeval ferns, fungi, lichens, and the like, and occasionally there are a few somewhat larger plants that look like little trees," Liszt wandered through the sanctuary. The ground was very moist, consisting of waterlogged soil, possibly with decaying leaves.

The sanctuary was vast; it had felt at least as large as Fresh Flower Town when seen from the sea, perhaps even larger.

At least from within the sanctuary, one could not see the end.

However, looking up, one could see the underwater world, with fish swimming just above the rainbow light shield. This made Liszt worry whether the fish might fall from the sea bottom, but clearly, he was overthinking it; after watching for a while, not a single fish fell down.

If they had, the sanctuary would have been filled with fish carcasses long ago.

Drawing a Knight's Longsword, Liszt began to clear the chaotic plants in the sanctuary, carving a path deeper into it.

Using Eye of Magic, he did not see any magical feedback glow, meaning these were ordinary plants.

However, it was not certain, as the plants' natural glow could interfere with the judgment standards of Liszt's Eye of Magic. He looked up at the "sky," and feeling the space was large enough, he called out Little Fire Dragon Leo – at this time Leo had a wingspan and body length of fifty meters each and was a massive creature.

"Oh ho!"

With a commanding roar, Leo swooped down, and Liszt instantly entered Dragon Knight mode.

Using Dragon Eye Trajectory, the world immediately became exceptionally clear and colorful, and distinguishing colors quickly saturated, making it easy to differentiate between magical feedback glow and the natural glow emitted by plants.

Just then,

the Dragon Eye Trajectory swept over the ground and immediately spotted glimmers of magic feedback from four locations, three of which were ordinary chaotic light, but there was one spot where the blue-white light shone brilliantly—this could potentially be the reflection of Water Attribute Superior Magic, though it seemed slightly different from the Superior Magic found in Ach and the Mermaids.

"Don't rush, let's check out the three ordinary lights first," he commanded Little Fire Dragon Leo to head straight for the nearest source of chaotic light.

He leapt down.

He soon found a plant nurturing an Elf Bug, which was sleeping on the underside of a leaf. The Cordyceps looked somewhat like a clump formed from banana tree leaves, devoid of flowers, with only a thick short stem and five large leaves. There were several similar plants nearby.

Unfortunately, they possessed no magic power and were not Magic Potions.

Liszt quickly contracted this Elf Bug, then left it to continue sleeping on the leaf—this secret miniature world had no animals, so the Elf Bug was safe.

He then rushed to the second and third locations.

Both places held Elf Bugs, with the Cordyceps being a strange large flower and a small tree that seemed bare but actually had leaves and bark of the same texture.

They were not Magic Potions, and after contracting them, Liszt let the Elf Bugs live on their own.

Since the Elf Bugs couldn't move far from their Cordyceps, he planned to see if he could transplant these three kinds of plants to land. If not, it seemed like the Elf Bugs had no value to be developed.

After dealing with the ordinary chaotic lights,

he quickly reached the center of the sanctuary, approaching the spot emitting the blue-white Superior Magic glow. To his astonishment, there was a segment of grey-white bone exposed on the ground. The blue-white light was emanating from the bone, which was in sections, large and seemingly the tail bone of some creature.

"Could it be... dragon tail bones?"

A sudden jolt hit Liszt's heart, and he glanced at Leo's tail, comparing it to this segment of bone, guessing that the dragon's body might be slightly larger than Leo's: "Have I discovered another dragon's remains? Let me excavate and see if I can find any mines!"

With excitement swirling, even a deceased dragon represented a treasure trove of great value.

And a thought flashed through his mind: "The great war of old must have centered around the Flame Islands, hence so many dragon remains are here on these islands and in the surrounding ocean!"

On Black Horse Island were the remains of the Fire Dragon.

On Mind Island was the Jade Dragon's Hind Leg.

Flame Island Dragon Pit Megamine held the remains and mines of the Titanium Dragon, Black Heart Iron Dragon, Lead Dragon, Bronze Dragon, and Mercury Dragon.

The entire sea was still tainted by the pollution of the Cursed Dragon.

Now, in the Shell Sea, another new set of dragon remains had been discovered, with Superior Magic not even faded—clearly, the sea's isolation of air slowed the decay of Superior Magic on the dragon remains.

"Vinnie, come and help me excavate the mine." He called out Bone Dragon Vinnie, then entered the Unity of Man and Dragon with her, both of them shuddering simultaneously.

Driven by a strange, refreshing feeling, Bone Dragon Vinnie swiftly dug along the tail bone with its dragon claws.

As the excavation progressed, the dragon bone was slowly revealed, yet no mine was discovered. Liszt couldn't help but ponder: "What kind of dragon's remains are these? Could it be another Elemental Dragon? Which element would it be—Water, Fire, Earth, Wind, Lightning, Light, Ice, Darkness?"
