Shi Wanyun was full of doubts.

Where exactly is this place?

But she knew that the way back was not here, but the passage that Xu Xin and the others came from.

So what's going on here?

Why didn’t those guys tell her about the situation on the third floor?

Could it be that they don’t know either?

Xu Xin was extremely excited.

He even started breathing faster!

He felt that there seemed to be something in the door waving at him, attracting him, calling him, asking him to enter quickly!

"boom……"

The sound continued.

The gap between the left and right doors slowly opened, the purple-black light became more and more conspicuous, and the bright white light emitted by the door was also slowly weakening.

The door does not open outwards, but inwards.

The door that opened inward seemed to be immersed in water, immersed in the purple-black light, and then disappeared with the bronze dagger on the keyhole.

At the same time, the purple-black light became stronger and instantly filled the original door position, and even spread outward by dozens of centimeters!

Then the rumbling sound stopped.

In front of them, a huge door that looked rather strange appeared!

The door frame was made of the original crystal material, emitting a soft, translucent white light, but inside the door was a purple-black starlight!

This time, there was no rotating purple-black vortex, nor was there any extremely dense-looking purple-black energy. There was only a purple-black sky that was as deep as the universe and seemed to suck people in... a starry sky?

There are also tiny stars emitting bright white light, which really makes people feel as if they are facing the universe.

"This... is so beautiful!" Lou Feier was immediately attracted. "Is this a portal? Why is it different from the previous ones?"

"Wow... I'm a little afraid to go in..." Zeng Tao leaned closer to Xu Xin, "I feel like if I step in, I'll lose myself in the boundless universe..."

Xu Xin subconsciously took a step forward.

He couldn't help but want to get in.

At this moment, two hands grabbed him and stopped his movements.

It was Jin Yue and Shi Wanyun behind him.

"What do you want to do?" Shi Wanyu frowned and asked, "Just walk in?"

"It's too dangerous." Jin Yue only said three words, but it also expressed her attitude.

"We definitely have to go in!" Zeng Tao had a different opinion from the other two. "Are we supposed to just open the door and do nothing but go home?"

"This door may allow us to return to the ground." Lou Feier also agreed to go in.

"There are other ways to get back to the surface!" Shi Wanyun no longer concealed the truth, "This is definitely not the way to get back to the surface!"

"...How do you know...Hey!" Lou Feier looked at Shi Wanyun suspiciously. Just as she was about to ask, Xu Xin suddenly took a big step and walked into the door without hesitation.

Even the two people behind him couldn't catch him.

Then, the purple-black color, like the abyss of the universe, suddenly expanded in all directions!

"ah!"

"Varied……"

The women didn't even have time to scream before they were swallowed up by the purple-black color.

The purple-black space instantly filled the entire third layer!

At this moment, several people disappeared.

…

At this moment, Xu Xin seemed to be floating in a silent universe.

There was no sound around, just dead silence.

He could hear his heartbeat, his breathing, and even the sound of his internal organs moving.

However, he was not panicked. Instead, he slowly looked around and his breathing gradually calmed down.

He whispered, "I'm coming."

“…You’re finally here…”

At this moment, a slightly vague voice sounded throughout the entire space.

The sound seemed to come from all directions and there was no way to find the direction.

But this voice was so familiar to him.

This was a sound he heard every day.

“…My future self.”

This is his own voice.
