Though he heard the notification of a successful capture, Dong Tianyu actually didn’t know where the hider had been hiding.

However, this was unimportant to Dong Tianyu; as long as the result matched his expectation, the process in between was irrelevant.

But after Dong Tianyu had cleared both the middle and top decks, he still hadn’t found any trace of the remaining hider.

At this point, Dong Tianyu’s brow was deeply furrowed, because every inch of the three levels of the Mysterious Realm had been covered by the flames from the flamethrower.

And the blackened areas left by the burning flames revealed no abnormalities when Dong Tianyu examined them with his Divine Sense.

All the signs indicated that the remaining person wasn’t simply hiding somewhere; he must be in a special place like that hider who could manipulate the Parallel Space.

With this in mind, Dong Tianyu fell into deep thought again, wondering if he had missed anything.

As Dong Tianyu paced back and forth, a sudden revelation struck him when he saw his own shadow behind him.

If there was one place in the Mysterious Realm that hadn’t been attacked from the beginning to the end, it could only be the area behind him.

Dong Tianyu picked up the flamethrower and fired directly at the position of his own shadow behind him; as the fierce flames touched the shadow on the ground.

The shadow, which should have disappeared with the light, remained on the spot as though it were a solid object, and this behavior convinced Dong Tianyu that his guess was probably correct.

The shadow on the ground gradually shrank as it continued to be scorched by the flames, until it finally vanished completely.

When the shadow completely disappeared, a black vortex appeared in front of Dong Tianyu, and the surrounding environment began to distort; the black vortex, like a black hole, rapidly absorbed everything around it into itself.

As the original scene was sucked into the vortex, Dong Tianyu found himself once again within his Companion Spiritual Treasure.

He grabbed the Mysterious Core in front of him and examined it closely, but no matter how he looked at it, the core in his hand was indeed a Black Devil Core, yet it was vastly different from the Mysterious Cores he had obtained before.

Although Dong Tianyu didn’t know why this Mysterious Core had taken this particular form, he wasn’t concerned with the appearance of the cores, so after a brief glance, he casually threw it on the ground.

At this moment, standing inside his Companion Spiritual Treasure, when Dong Tianyu tossed the Mysterious Core to the ground, it disappeared from the surface like a stone thrown into water, silently.

Once the Companion Spiritual Treasure completely absorbed the Mysterious Core, Dong Tianyu, through communication with his Companion Spiritual Treasure, finally understood the core’s function.

It was not very different from the Black Devil Cores he had previously acquired, but as Dong Tianyu’s Companion Spiritual Treasure continued to evolve, the growth effect from devouring those previous cores had begun to diminish, whereas the absorption of new varieties of cores did not reduce the growth effect.

After understanding this information, Dong Tianyu could only chuckle to himself.

He was now at a depth of about one hundred meters underwater, a place rarely visited by survivors under normal circumstances.

Though martial artists, with increasing Martial Cultivation, are much stronger than the average person in terms of holding their breath or resisting water pressure,

as the water grew deeper, the salvage teams also gradually disbanded, so now, there were very few who would dive to these depths.

However, Dong Tianyu still felt a bit puzzled; after all, even though he had dived this deep, he had still encountered a Mysterious Ship, which was indeed somewhat unusual.

As Dong Tianyu continued to navigate underwater with his Companion Spiritual Treasure, this time he kept his Divine Sense expanded to the fullest range due to his previous experience.

It was precisely for this reason that when the next Mysterious Ship approached, it had been detected in advance, and through Divine Sense, Dong Tianyu had "clearly seen" what this Mysterious Ship looked like.

Just as Dong Tianyu had speculated, the appearances of these underwater Mysterious Ships had changed; they closely resembled submarines.

Due to the unique conditions underwater, to acquire more Mysterious Cores, one could only gain the Core of the Mysterious Realm by passing through the Fusion Mystic Realm.

Perhaps it was because each Mysterious Realm appeared through fusion, so the contents of each realm were more or less the same.

Maybe it was due to his first-time experience, but Dong Tianyu’s rate of passing through the Mysterious Realms became increasingly rapid.

Fortunately, at this depth underwater, Dong Tianyu was the only one hunting, without the competition that existed above the surface.

Besides, almost all the ships down here were Black Ghost Ships; Dong Tianyu had not found any red or dark green ones from the beginning to the end.

As Dong Tianyu breached more Mysterious Realms, the quantity of Mysterious Cores absorbed by the Companion Spiritual Treasure kept increasing, and naturally, its size also continued to grow.

Despite the oppressive darkness underwater, it was fortunate that the Cave was bathed in sunshine, and with the company of the Canaries, Dong Tianyu didn’t develop any psychological issues from spending extended periods in a dark environment.

Actually, Dong Tianyu was still somewhat curious, if he continued to cultivate his Companion Spiritual Treasure, which had already evolved into a submarine, what it would turn into upon a further evolution.
