The same lines on the small attic made Luo Xiu's eyes slightly distracted.

"Nine-story building, original...... This is the secret of the Nine-Story Building!"

Luo Xiu is almost certain that the reason why this restaurant is called by Ye Zhong - Nine-Story Building is definitely because of the nine-story pavilion!

In other words, the remaining seven floors are all closed.

Only through this pattern can it be teleported to the so-called remaining seven floors.

"The ingredient warehouse on the first floor should have absorbed the spirit stone and been opened!"

"And the second floor, it is also because of the absorption of the medium-grade spirit stone, which opened the texture of the teleportation array!"

"In other words, the secret of opening the Nine-Story Building lies in the spirit stone!"

Luo Xiu speculated there, and he was almost certain that this kind of speculation was inseparable...... The spirit stone is used for cultivation in the kitchen, and this nine-story building can actually absorb the spirit stone to restore the texture?

"That's ...... It's a magic weapon!"

"Now only through the spirit stone can it recover all its previous power!"

Luo Xiu looked at the lines in a daze, but he knew in his heart that if he wanted to open all the secrets of the Nine-Story Building, he had to prepare enough spirit stones.

“......”

Where is this money, it is really hard currency!

Luo Xiu sighed, but a trace of doubt flashed in his mind.

"This small attic is the key to opening the third floor, what is the secret room that is teleported in the room?"

"Practice room?"

Luo Xiu thought about it, but looked around to see if there were any other lines.

But obviously, there are now 3 ...... in the entire nine-story building One is the food storehouse, the other is the practice room, and the other is the key to opening the third floor of the nine-story building.

"According to the setting of the ingredient library, it is possible that the place corresponding to the texture is the place where some spiritual ingredients are stacked!"

Luo Xiu now has the feeling of playing an RPG secret room game, this nine-story building is full of hidden mechanisms, but it needs spirit stones to open.

"Let's go to the secret room first!"

Luo Xiu returned to Ye Chong's room, looking at the gloomy lines, Luo Xiu tried to step on it, and suddenly ...... Once again, the light flashed.

Then, it was dark in front of him, and when he reacted, Luo Xiu arrived at the secret room.

The secret room looked empty, Luo Xiu only subconsciously looked at it before, thinking it was a closed dark room, but now when he saw it, he was taken aback.

The four walls on the front and back and left and right are actually carved with countless strange patterns.

And each strange pattern corresponds to a dark grid.

"Is this grid empty?"

Luo Xiu walked to the nearest square hidden grid, which seemed to have a humanoid pattern painted on it.

Tuk!

After three knocks, a hollow voice suddenly came out.

Luo Xiu's guess was not wrong, behind these patterns, it was indeed hollowed out and made into dark grids.

Needless to say, you should put some treasures.

"Why didn't the old man say anything about it before he died?"

"It's buried very deep, and my own daughter didn't say anything?"

Luo Xiu didn't understand Ye Chong's approach, but he ...... Maybe he also has a last resort.

"How do you open these grids?"

"Could it be that you also need spirit stones?"

Luo Xiu pushed it hard, but the dark grid didn't move, as if it was embedded in the wall.

I tried a variety of methods like this, but still found nothing, Luo Xiu's eyes suddenly fell on the pattern of the dark grid.

This time, he found a trace of pattern.

"This humanoid pattern should be the corresponding human ......"

As soon as he finished saying this, a memory suddenly flashed in Luo Xiu's brain.

Writing!

Isn't this the text of this world?!

This is herringbone.

And under this herringbone, there are two small words: refining body.

"Refining?"

Luo Xiu muttered for a moment, and reacted instantly: "Exercises, exercises for refining the body!"

Swish!

He immediately looked at a dark grid next to him, which was also a herringbone pattern, but it was written underneath - Enlightenment!

Refining, opening, and spirituality!

Ice, Lightning, Fire......

Each group case corresponds to a text.

Luo Xiu looked at the dark grid in the room blankly, and instantly lost his mind.

These dark grids are actually all exercises.

In the thunder character pattern, it corresponds to the cultivation spirit of the thunder system, the ice system...... That's the practice of ice cooking.

As for the refining and enlightenment at the beginning, Luo Xiu could guess that this should be the level of cultivation at the beginning of the kitchen cultivation.

"This nine-story building...... It's not easy!"

Luo Xiu felt more and more that the restaurant left by his father-in-law became more and more mysterious.

"If I hadn't crossed over, I would have almost been taken away by that guy from Li Yuan!"

Luo Xiu thought about it with some palpitations, but found that ...... Among so many dark grids, there is a dark grid, which is very special.

There is not a single text on it, and it is bare in the countless text compartments, which seems a little out of place.

The four walls, just like this, without a trace of pattern or text, are extremely monotonous in the middle of the wall, as if countless dark grids are clustered around it.

"Quite strange, and ...... Located in the middle, there must be a demon when things go wrong!"

Luo Xiu walked in front of the dark grid.

The hand gently stroked the dark grid, and when Luo Xiu was just about to observe what was special, a huge suction force suddenly almost swallowed his whole person.

"What?"

Luo Xiu's pupils shrank, but the suction disappeared cleanly in the next second.

Smack!

A slight voice came from the darkness.

Luo Xiu jerked his hand back, only to find ...... At some point, the dark grid turned into a wall again.

"Huh?"

This scene is too weird, Luo Xiu looked at the dark grid, just ...... Your hand seems to have reached in.

"Then ...... Try again!"

Luo Xiu gritted his teeth and slammed his palm against the dark grid.

Suction once again made Luo Xiu's heart jump.

But the hand did reach into the dark grid...... Luo Xiu looked at the dark grid carefully, but found that a light curtain like water ripples appeared on the surface of the dark grid.

His arm seemed to be stretched into this layer of water ripples.

This dark grid sealing layer is actually such a strange substance.

Isn't it a wall?

However, the situation did not allow Luo Xiu to think so much, and the hand that reached into the dark compartment seemed to have caught something.

When ordinary people encounter this kind of thing, it is estimated that they are already scared half to death.

After all, behind this wall, no one guarantees anything, and it's strange if you don't feel anything moving.

But Luo Xiu is notoriously bold, otherwise he would not have gone to the deep sea of Bermuda to catch king salmon and traveled to another world.

Whew!Whew!

After sweeping the dark grid, Luo Xiu found that the grid was not very large.

The hand stretched out slightly, and it was already at the end, and I touched it up and down, left and right, and only one thing I had just touched was placed in the dark grid.

With a snap, Luo Xiu withdrew his hand from the dark grid.

When I looked closely, a volume of ancient books appeared in my hand.

This is what is placed in the dark compartment.
