Hotel room.

Lan Xi was lying on the bed, looking back and forth with a black Rubik's cube in his hand.

This black Rubik's Cube is the mission item that the Supreme Research Institute asked her to escort.

"How do I open it?" Lan Xi touched his chin.

This Rubik's Cube is pitch black, and there is no pattern on it, and she has tried it with mental power to probe and recognize the Lord with blood, but all of them are invalid.

She didn't think that what would make the Supreme Institute so important was just an ordinary toy.

At this moment, the moonlight outside the window suddenly spilled in.

I saw that the original black Rubik's Cube gradually became translucent, and some scattered pattern fragments appeared from inside the Rubik's Cube.

Lan Xi suddenly lifted his spirit and began to turn the Rubik's Cube.

In a matter of moments, she put all the pieces together.

When the last pattern fragment returned to its place, Lan Xi only felt a flash of bright light in front of her, and then she came to a dark world.

This world is empty, there are only five gates, on which are written in ancient characters, books, pills, instruments, charms, and spirits.

Looking at these ancient characters, Lan Xi's pupils suddenly shrank.

"Ancient Cultivation Civilization!"

These ancient characters are naturally recognized by Lanxi.

In the world she originally lived in, she experienced two periods, one was the period of ancient civilization and the other was the period of scientific and technological civilization.

A major catastrophe that led to a fault line between civilizations in two periods.

The ancient cultivation civilization almost completely disappeared in this disaster, and only some basic cultivation techniques remained.

As a mercenary, Lan Xi has certainly practiced those exercises.

The words on those exercises are the words of the ancient civilization period, and they are exactly the same as the words on these five gates!

Lanxi took a deep breath and walked towards the first gate.

When Lanxi pushed open the door, it was greeted by a huge library of books.

Rows of bookshelves, as well as dark grids inlaid on the walls, are all filled with various books.

It's just that, except for the front row of bookshelves, all the other bookshelves are prohibited, and you can't get close to them at all, let alone read the books on them.

Next, Lanxi entered a few more doors.

Inside these doors, there are a refining pharmacy, a refining room, and a talisman room.

Corresponds to the three words Dan, instrument, and Fu.

As for the last "spirit", inside the gate, it turned out to be a small world, the area is not large, only a few hundred square meters, many common elixirs that only exist in the ancient civilization period, can be seen in this small world!

Although Lan Xi had realized that these five gates were not ordinary, he was still deeply shocked at this moment.

……

Back in the real world, the Rubik's Cube in Lan Xi's hand has disappeared, and the five gates appear directly in her sea of knowledge.

"Master, you finally appeared, just now you suddenly disappeared, but it scared me to death." Mo Bao came to Lan Xi and patted his chest anthropomorphically, his face full of worry.

"Don't worry, I'm fine." Lan Xi smiled.

At this moment, the mobile phone at the bedside suddenly rang.

Lan Xi took it and took a look at it, and found that it was the secretary next to her mother who called.

"Hey." Blue Creek picked up the phone.

"Miss, no, madam, she fainted!" Secretary Liu's anxious voice came from the phone.
