When the cow stepped onto the island initially, it encountered no danger. However, when it reached the spot where the Shark People were previously seated around the bonfire, a thick figure suddenly burst from the ground.

Although its appearance was very similar to those things that were burnt by the fire, its size was more than a hundred times larger than those smaller creatures.

When it burst from the ground, nine-tenths of the entire island fell into its mouth, like earthworms squirming out of a straw, its body hugging the perimeter of the island as if its outlines were restraining the monster’s body.

The cow that had been on the island was first thrown into the air, and then naturally fell into the mouth of the monster.

Luckily, Dong Tianyu had not directly landed on the island just moments before. Otherwise, Dong Tianyu, having lost the ability to fly, would definitely not have escaped the abyssal maw.

Watching the huge creature gradually retreat back, Dong Tianyu suddenly felt that something was still quite amiss.

Setting aside the competitive mode of the Bloody Mysterious Realm, having experienced many Black Mirage Realms, Dong Tianyu knew that the strength of Mysterious Realms was directly proportional to the size of the Mysterious Ships from the outside world.

Unless the Mysterious Ships emitting a dark green aura operated under different rules from those with a black aura, such a great disparity shouldn’t exist.

Waiting until the enormous creature completely withdrew back beneath the island’s surface, the deep pit that had been exposed started filling up with yellow sand as the damp beach sand refilled the surface of the island.

The faint sense of danger surrounded Dong Tianyu’s heart again. To confirm his thoughts, Dong Tianyu took a rabbit out of the Cave and forcefully threw it onto the island.

As soon as the rabbit landed, Dong Tianyu noticed that the creatures that should have been burnt to death were re-emerging from the sand,

and when something passed by, these creatures suddenly burst out of the sand and bit into the rabbit.

Whether those creatures had a paralyzing effect or it was due to several attacking at once effectively killing the rabbit, the rabbit, though initially startled and jumpy, became stiff mid-air and then fell heavily to the ground.

As the rabbit lay motionless on the ground, those creatures initially hidden in the sand swiftly coiled around the rabbit’s body and slowly dragged it back into the sand.

Seeing this scene, Dong Tianyu shivered involuntarily, contemplating that if he had landed on the island unknowingly, he probably would have ended up just like the rabbit.

This abnormal intensity made Dong Tianyu suddenly realize that the massive creature hidden beneath the island was merely an enlarged version of those smaller creatures in the sandy ground.

If that were the case, then aside from its unspeakable abyssal devouring ability, that large creature likely lacked any other abilities.

Just as Dong Tianyu was preparing to replicate his previous actions, a question suddenly arose in his mind: the source of those little creatures hidden in the sand on the island was clear, but where did those shape-shifting Shark People come from?

It seems that this small island, where all areas were visible at a glance, must still be hiding some secrets Dong Tianyu hadn’t discovered.

Seeing the small boats surrounding the island again, a chilling idea suddenly emerged in Dong Tianyu’s mind.

But now, with only Dong Tianyu alone here, there was no way to verify what he suspected.

Just as Dong Tianyu was trying to dismiss the idea, preparing to replicate his last action, a tender white arm suddenly stretched out from the sandy center of the island.

Following this arm as a support, a girl with skin as delicate as cream climbed out of the sand, her lower body still in the form of a fishtail as she emerged from the sand.

Having witnessed the entire process, Dong Tianyu instantly understood where those Shark People he initially encountered had come from.

Seeing the alluring figure on the island, Dong Tianyu decisively took out the sniper rifle from the Storage space. As soon as the figure looked towards Dong Tianyu, gunfire rang out again, and the shark girl fell to the ground.

As blood flowed from the head of the shark person and seeped into the sandy soil, the body of the shark person that had been lying on the sand began to sink slowly into it without any external force.

Having observed the whole process again, Dong Tianyu roughly understood the situation on the island and immediately took out a whole ox that had been slaughtered from the Storage space.

Since the Storage space had a preservation effect, the whole ox, just fetched, was as fresh as if it had just been slaughtered; the body still had residual warmth.

Dong Tianyu took out a pile of C4 Explosives from the Storage space, stuffed a timer detonator inside, filled the calf entirely, and then stitched up the opening of the ox’s belly with a clasp.

He then threw the whole ox with force towards the center of the island to attract the big creature underground as quickly as possible, and also threw a few bags of warm ox blood on the ox.

As the ox blood seeped down through the body into the sand below, the motionless ox, just like the dead shark person’s body, began to slowly sink into the sand.

Seeing the body of the ox gradually sink, Dong Tianyu immediately maneuvered the Jade Ship away from the island.

Only when Dong Tianyu felt he was at a safe distance did he stop the ship and then stood at the bow, silently observing the island.

As time reached the set moment for detonation, the initially calm water surface began to ripple slowly, and then the sand covering the island burst skyward.

"This should kill that creature, right?"

Unlike other explosives, C4 looks like modeling clay and can be shaped into any form, so when Dong Tianyu stuffed the ox’s stomach full, it was meant literally.

The explosive power of C4 is ranked among the top ten of all explosives. Don’t underestimate this number; even nuclear and hydrogen bombs are included in this ranking, which speaks volumes about the significance of this ranking.

As the sand that was blasted into the sky began to fall back to the water surface, the island that had been confining the big creature was also destroyed, just as Dong Tianyu was considering his next move.

Suddenly, a crack appeared in the clear blue sky, and like a crack on glass, it began to extend and sprout branches like a tree trunk.

When the crack filled the entire sky, suddenly a crisp shattering sound was heard, and the entire Mysterious Realm disappeared in the blink of an eye. By the time Dong Tianyu came back to his senses, a dark green Mysterious Core had fallen in front of him, landing directly on the deck of the Jade Ship.

But as Dong Tianyu instinctively bent to pick up the Mysterious Core that had fallen on the deck, he realized that the deck that should have been there had vanished.

Just as Dong Tianyu was wondering where the Mysterious Core had rolled to, his Sea of Consciousness suddenly received information transmitted by the Companion Spiritual Treasure; it turned out that when the Mysterious Core had touched the deck, it had been absorbed directly by his own Companion Spiritual Treasure.

Because it had absorbed the dark green Mysterious Core, the Companion Spiritual Treasure could now make a choice in different directions, and after making a choice, it could obtain a corresponding external equipment.

It was at this moment, Dong Tianyu discovered an unspoken feature of the Companion Spiritual Treasure; that is, when Dong Tianyu retracted the Companion Spiritual Treasure into his Sea of Consciousness.

If there were other life forms inside the Companion Spiritual Treasure, they could not be directly retracted unless all life forms inside were expelled. Otherwise, retrieving the Companion Spiritual Treasure would require a considerable amount of spiritual power, and if the spiritual power was insufficient, it would instead consume the person’s Life Vitality.

Apart from not being able to retract living creatures, non-living items also could not be taken into the Sea of Consciousness. When the Companion Spiritual Treasure was retracted into the Sea of Consciousness, the items left inside the Companion Spiritual Treasure would appear exactly at the spot where the Companion Spiritual Treasure had disappeared.

Of course, this process also required expenditure of spiritual power, although compared to living bodies, moving inanimate objects out of the Companion Spiritual Treasure does not consume much spiritual power.

Of course, this only applies to ordinary items; for Divine Artifacts and the like, the spiritual power required may not be much less than that needed for living entities.
