The sudden sinking really startled Luo Yu, but when he saw the protective glass around him, he also eliminated the fear in his heart and looked around.

"System, this is underground, right?" Luo Yu asked tentatively.

"Yes, host. ”

"You're not going to transform the underground, are you?" Luo Yu said in surprise.

"Yes, since the host's house is small, many things cannot be implanted, so the system chooses to find a new ......way underground," the system's cold voice explained.

"Huh, you're not sabotaging...... No, it's good if you're happy, I don't have any opinion!"

Seeing that the system decoration would not even let go of the underground, Luo Yu wanted to say a few words that were not right to refute and refute with the system.

But after thinking about it, the conduct of this system doesn't seem to be very good, if you accidentally offend it again, and this day becomes half a day again, will it still make people live?

Thinking of this, Luo Yu couldn't help but shudder, and quickly dispelled the idea of going against the system, and chose to compromise more rationally.

"Ding, welcome to the underground castle of the Xiantong Beast Pet Shop!"

While Luo Yu was thinking wildly, the voice of the system sounded again, and at the same time, it also pulled him back to reality from the outside of the imaginary object.

"Underground castle?"

Luo Yu was surprised, looked up and looked ahead, only to see a white castle-shaped building standing in front of him.

"I'll go, system, can you use such a big deal? This is too spectacular!"

Looking at the white castle like glass in front of him, Luo Yu was stunned for a moment, this appearance is too luxurious, it's just a beast pet shop, can it be so extravagant and wasteful?

"Host, this underground castle is the foundation of the Xiantong Beast Pet Shop, in addition to the pharmacy room, there are also breeding rooms, medical rooms, etc., which are all built for the operation of the beast pet shop in the future. The system explained.

"Oh, is that so, then I have to take a good look!" Luo Yu suddenly became interested when he heard this, and he strode towards the white castle.

"Ding, since the host is entering the underground castle for the first time, please do the fingerprint verification first!" the system's voice came again.

"Fingerprint verification? Is this it?" Luo Yu heard this, looked around, and when he saw the electronic screen next to the door, he also pressed it directly.

"Ding, fingerprint verification is ......"

"Ding, the verification is successful, welcome to the underground castle ......"

The cold electronic voice sounded one after another, and at the same time, the gate of the castle also opened, and Luo Yu saw this, and hurriedly stepped in.

As soon as he walked into the castle, Luo Yu felt as if he was in a fairy tale palace, with a long red carpet spread on the ground, more than fifty meters long.

On each side of the red carpet there was a staircase leading to the upper floor, and at the straight end of the red carpet was a black door inlaid with many gems, but I didn't know where it led.

"System, where does that door lead?"

Luo Yu felt strange in his heart, pointing to the black door and asking at the system.

"Host, you can take a look for yourself, maybe there will be a surprise!" the system said with a hint of emotion for the first time.

"Huh, see for yourself, there won't be any conspiracy, right?" Luo Yu heard this, and hesitated slightly, he didn't doubt at all that the system would play a prank.

However, this person's curiosity is always so great, and after some psychological struggle, Luo Yu still couldn't control himself and walked towards the black door.

"Ding, please verify your identity ......"

"Do you want to verify it again?" Luo Yu frowned, as if he was a little impatient, and said with a displeased face.

"The host, the back of this door is very special, so no one but the host is allowed to enter, so there must be authentication as a security ......," the system explained.

"Oh, then I really want to take a look at the back of this door, what is so special!" Hearing what the system said, Luo Yu's curiosity suddenly increased.

"System, it doesn't seem to be anything to verify?" Looking around, Luo Yu didn't find anything that could be verified, and couldn't help but ask with some doubts.

"Host, just put your palm into the red heart on the black door, and the system will automatically verify it......"

The system's voice fell, and Luo Yu also directly put his palm into the red heart on the black gate, and in an instant, the black gate automatically opened to the left and right.

And with the opening of the black gate, the mystery behind the gate was slowly revealed, completely revealing in front of Luo Yu's eyes.

"I'll go, system, this...... Could this be the Phantom Beast Forest?"

Looking at the green grassland in front of him, as well as the cool streams, as well as the towering mountains, coupled with the wooded forest not far away, Luo Yu couldn't help but be a little stunned.

"Woo ......"

Just as Luo Yu was stunned, a huge figure flew in front of him, rolling up a gust of wind and sand.

"This ...... Is this the Fengluan Bird, one of the five divine birds?" Looking at the cyan figure flying in the air, Luo Yu couldn't help but lose his voice.

"Yes, host, this is indeed the Wind Luan Bird, and this is the phantom beast space of the beast pet system. ”

"As for the Plains of Grass in front of you, further afield, there are sand dunes, ice fields, valleys of flames and other places, where there are more phantom beasts. ”

The voice of the system sounded, and it also told Luo Yu all the secrets behind this door.

"I'm a good girl, system, there are so many phantom beasts, even the legendary divine bird, why do you still let me catch the phantom beasts?

"Host, the phantom beasts in the system space are all high-level phantom beasts, and the potential value is very high, if they are sold frequently, it will cause unnecessary sensation. ”

"Besides, judging from the host's current personal ability, none of these phantom beasts can be captured by you now, so you should honestly complete the system task, and talk about it later!" the system said mercilessly.

"Damn, is there a mistake, you can't catch it, you can't sell it, you still hook up with me? Isn't this a typical take off your pants, you told me that my aunt is here, I can't do it!"

Hearing the system say this, Luo Yu also said with disdain.

"Ding, the host has been detected to be suspicious of despising the system, and the mission time has been halved again, and there is still half a day left!"

"Ding, the timer starts, please complete the task as soon as possible, otherwise the punishment will be doubled!"

The sound of the system sounded one after another, causing a mouthful of old blood to spurt out in an instant.

"Holy, system, you're ruthless!"
