Cave Refuge

However, according to the principle of confidentiality, Grayson Todd was not supposed to divulge any information about the Secret Realm to others.

It is known that in this period of frequent Natural Disasters, should someone discover and occupy a Secret Realm, they would be rid of the threats of natural calamities.

After all, although the time flow in the Secret Realm is consistent with the real world, the Secret Realm is not interconnected with the real world.

If this had been before the Natural Disasters, those immovable Secret Realms would essentially be no more than a large storage space.

But now, if a Secret Realm does not interconnect with the outside world, it means that no matter what dangers arise in the outside world, they won't affect the space within the Secret Realm.

To put it simply, after taking refuge in a Secret Realm, one would be completely free from the threats of various Natural Disasters.

It's just that the majority of the Secret Realms discovered by the Imperial Court are small in size, roughly one hundred square meters with a height of about three meters, such small space can at most accommodate a single family.

The largest Secret Realm space discovered by the Imperial Court is only as big as a few acres of land, with a height of about ten meters or so.

A Secret Realm of this size, if fully occupied, could at most house a few hundred to a thousand people.

After discovering and verifying the safety of these Secret Realms, the Imperial Court transformed them into laboratories and safes for storing high-value items.

People are selfish, knowing that once they live inside a Secret Realm, they would no longer suffer the threat of relentless Natural Disasters, some families aware of the Secret Realms suddenly became somewhat crazed.

If the arrival of the Natural Disasters had left everyone pessimistic about the future, then upon learning of the Secret Realm's information, those people started to search for Secret Realms frantically.

After all, finding the location of a Secret Realm could ensure safety from Natural Disasters for a generation; such a situation in ancient times could truly be considered as a foundation for a family to establish and secure their legacy.

Grayson Todd this time came to verify whether those Bat Monsters were using the Plane Transmission Channel to return to their home Plane, or if they had found a nearby Secret Realm and directly hidden inside it.

From the moment Grayson Todd arrived, he had been carefully observing the sea around him, and throughout, he had not found any corpses of Bat Monsters, which sparked his suspicions.

After all, there are only two possible scenarios for this outcome: either all those Bat Monsters have returned to their original Plane of residence, or they really found a Secret Realm nearby and, except for those who stayed behind to cover the retreat, all the other Bat Monsters have hidden inside that Secret Realm.

Upon arrival, the Imperial Court roughly estimated the number of Bat Monsters converging here.

If those Bat Monsters were using the Plane Transmission Channel to return to their own Plane, that's fine because the other side should also be a complete world.

However, if those Bat Monsters are hiding in a nearby Secret Realm, then based on the number estimated by the Imperial Court, even after halving that number, it would still be a significant quantity.

If there truly is a Secret Realm large enough to accommodate that many Bat Monsters, just imagine how vast that Secret Realm would be.

Thinking this, a fierce glint flashed in Grayson Todd's eyes, which then disappeared in the blink of an eye.

Ordinary people might not notice such details, but Dong Tianyu was no ordinary person. It's important to note that at this moment, the area within a fifty-meter radius was always under the coverage of his Divine Sense.

Therefore, within this range, any slight movement could not escape the notice of Dong Tianyu's Divine Sense.

Although Dong Tianyu sensed something off with Grayson Todd, since they had only just met, and the fact that the man was a friend of Robinson William, Dong Tianyu, with the thought that it's better to avoid unnecessary troubles, assumed he was mistaken and therefore did not speak further on the matter.

In fact, Grayson Todd was wrong from the start. The Bat Monsters continually converging here and then disappearing this time had all been eliminated by Dong Tianyu.

The Hundred Ghosts Banner devours souls, the Bloodthirsty Banner refines blood, the White Bone Banner extracts marrow.

As long as it's a carbon-based life form, the Three Flags can make it disappear instantaneously, leaving not even remains behind.

It's exactly because the Three Flags leave no traces when cleaning up biological matter that it gives rise to Grayson Todd's unusual thoughts.

When those Bat Monsters were converging towards this area, the overbearing scene was so overwhelming there was no need to count to estimate their approximate numbers.

Yet after those Bat Monsters had gathered here, they disappeared at an extremely rapid pace. If one were to say all the Bat Monsters died, then no useful information could be found here.

After all, the sea is different from the land; if there was an encounter or battle, an experienced fighter could always deduce useful information from the arrangement of the scene.

But now, they were in the sea, so any traces left after a battle also disappeared without a trace amidst the ebb and flow of the tides.

And when Grayson Todd arrived here, he saw Dong Tianyu standing in the air, controlling his sword alone, which led Todd to believe that Dong Tianyu should know what happened here.

Of course, Grayson Todd disagreed with Robinson William's statement mentioning a single person stopping the return of the Bat Monsters. Merely looking at Dong Tianyu's pristine appearance, one could deduce that he hadn't been involved in recent battles.

Knowing that Grayson Todd, who had already ascended to Grandmaster, had an exceptionally keen sense of smell, he could confirm via scent that Dong Tianyu didn't carry the smell of gunpowder, solidifying his belief that Dong Tianyu hadn't participated in the recent battle.

Although deep down Todd believed that Dong Tianyu was already standing there before he arrived,

the disappearance of the Bat Monsters must have also occurred before Dong Tianyu's arrival. Otherwise, Dong Tianyu's clothing wouldn't be as neat and tidy as it was, with not a trace of combat to be seen.

Even though Grayson Todd had his own suspicions, considering the atmosphere that had built up, he still proceeded with routine questioning: "Do you know how those Bat Monsters disappeared?"

"I know!"

At this moment, Grayson Todd was somewhat indifferent because he had already completed the majority of his task, and his leader wouldn't order him to look for the Bat Monsters or tell him he couldn't return if they weren't found - those were absurdities.

"I don't know either, wait… what did you just say?" Todd seemed to have recalled Dong Tianyu's response, and as if he hadn't heard it clearly before, he asked again.

Seeing the conflicted expression on Grayson Todd's face, and since Dong Tianyu was also a man, there was no intention to tease him further. He affirmed once more, "I know how those Bat Monsters disappeared."

Confirming that he hadn't misheard and that Dong Tianyu indeed claimed to know how the Bat Monsters disappeared, Grayson Todd, somewhat incredulously, said, "Then can you tell me, how did the Bat Monsters disappear?"

Standing to the side, Robinson William was also curious, wanting to know what answer Dong Tianyu would give to Grayson Todd's question.

But before Dong Tianyu could speak, several Companion Spiritual Treasures on the sea surface were speeding towards them at an extremely fast pace.

Seeing this scene, the three people on the deck exchanged glances, questioning with their eyes whether those people rushing towards them were summoned by the opponent to take up space.

When the three saw the same expression on each other's faces, they immediately understood that those approaching were likely not called by the other party.

Just as Grayson Todd was about to ask again, accompanied by whistling sounds of cutting through the air, several people landed directly on the deck of Todd's Companion Spiritual Treasure.

Looking at the arrogant expression on their faces, Grayson Todd uttered a light scoff before they could speak: "Scram!"

With his low roar, those who had landed on deck as if evading a fearsome beast, immediately turned and jumped into the water without looking back.
