My World Traveling System: The Harbinger of Death

-----

CRAAASH!

…

"Eh?"

A large, almost three-meter-big flying log owl would be able to easily break a mere window, but this one wasn't able to do that.

The entire group was left rather perplexed, how come they were unable to do that?! Breaking a window was something even a child with a rock could do!

But how?! How come they couldn't break a single window? This was unthinkable of! This was… pure insanity.

The men couldn't believe it, so they ordered the monster to hit the window several times, several windows, in fact, but nothing happened…

"What the heck? I've never seen such strong windows before!"

"What do we do then?"

"Then we'll have to go a step beyond and just infiltrate inside!"

"Okay then!"

"Ghost Jellyfish, use Ghostification!"

FLASH!

Suddenly, the several Ghostly Jellyfishes used a special Ability they had, which could turn people into ethereal-like ghosts for a few minutes, it was actually a move used to turn enemies int Ghost-type monsters so they would become weak to Ghost-type weaknesses, such as other Ghost-type attacks!

However, it could be used very much in people too, making them capable of crossing through walls and more. Of course, monster pets with such a move were very rare, and this jellyfish was actually imported from the outside of the Empire and was rather expensive.

It had two children after years of growing up, it spawned two eggs the owner raised. And these powerful jellyfishes could sell for a fortune if he were to attempt to sell them in the black market.

However… he used them for nefarious purpose, abusing their ability, they used it to infilter inside buildings of competitors, ruining their shop and stealing their things…

The people quickly attempted to enter the house, as they finally managed to, reaching the inside of the manor-like building, as they were greeted by a vast empty area.

"So we are here… where's the storage room?"

"Wait, there's a lot of rooms there…"

"Yeah, does he stores monster pets there? We should steal them too…"

"Damn, this place is so luxurious!"

"He even got a kitchen?!"

…

Meanwhile, Frank who had gone back to Earth and was sitting over his couch while looking at his phone while having Alexander napping over his torso, suddenly saw a system notification.

[Master, there are intruders inside the Monster Pet Nursery]

"Eh? What?" asked Frank in surprise.

[They attempted to break the building's windows, but the windows are too strong for them to do that, however, they have now infiltered inside by becoming non-corporeal beings, something that the Monster Pet Nursery couldn't block. They might attempt to rob you]

Frank was left surprised, they really wanted to take revenge on him so soon?! Or could they be not related with the Black Eye Organization?

"Damn it, alright let's go-"

"Master, wait!"

Suddenly, Yurei stopped Frank from going to Gaia.

"What is it, Yurei?" asked Frank.

"Let me go with you! I heard you have a new building, right? I can possess it and make it an extension of myself! I already have one inside your divine realm as well, right?" asked Yurei.

Indeed, Yurei had the power to have multiple bodies made of buildings, although the original house of Gwendolyn had been moved here and transformed in appearance to look like this, there was also a manor in the City of Terra which Frank had bought and converted into Yurei as well.

He really didn't liked to abuse of this power of hers, as he found it was quite unfair to force her to do this, but Yurei offered herself so he had no other option than agree to her request, but he didn't really knew if it could work, as the entire Monster Pet Nursery was more of an extension to the system…

But it was worth a try.

"Okay, come with me." Said Frank.

Yurei quickly gathered her phantasmal powers as her beautiful ghostly maid form emerged at Frank's side, with long silvery-white hair and ghostly blue eyes, she quickly decided to go with Frank.

"I am ready, Master."

But there was a problem, the little Alexander was still sleeping leisurely over Frank, and Frank really didn't wanted to bother his adorable son as he took his nap.

As a father, Frank had to take care of this too, so he gently held his son on his arms and teleported near his cradle, leaving him sleeping soundly there. The baby was profoundly asleep, so he thankfully didn't woke up.

"Phew…"

Frank sighed in relief as he flew away to Gaia with Yurei's embodiment.

FLASH!

He quickly emerged atop the Monster Pet Nursery Building, as Yurei looked down the building.

"Then I am going! I will take care of any thugs that try to get inside!" said Yurei.

"Sure, thank you, Yurei." Said Frank.

FLAAASH!

Yurei suddenly merged herself with the entire building, as the entire building exuded a powerful aura of phantasmal energy. The entire building was made by the System itself, so Frank didn't knew if it could work, but it apparently worked…

Ding!

[Yurei] has successfully bind to the [Monster Pet Nursery]

[Yurei] has been catalogued as a Pseudo Monster Pet]

[Yurei] has developed a Beast Core]

[Yurei] Beast Core has merged with her Death Core, forming the Divine Death Beast Core]

[Yurei] total capabilities and power is increasing exponentially…]

[The [Monster Pet Nursery] has merged with [Yurei]

[The [Monster Pet Nursery] has evolved into [Phantasmal Haunted Monster Pet Nursery House]

[New Functions had been unlocked]

[New Abilities will develop]

"Wow, what…?! I didn't knew this could happen…" said Frank.

[Master, it appears the fusion was successful, Yurei had become the building itself, which is also a part of the System, therefore, the building itself now shares powers with her and vice versa]

"Wait! Isn't this a bit broken?" asked Frank.

[Yes, precisely]

"Oh…"

Meanwhile, in the interior of the Monster Pet Nursery, those that had infiltered inside were not even able to tell that the building they had entered to was now a phantasmal entity, glaring down at them viciously!
