The corners of his mouth curled a little, Chu Feng pushed open the door and walked out.

It was very quiet outside, and there was not a single guard or servant in sight, Chu Feng came to the courtyard and walked towards the fourth prince's bedroom while looking around curiously.

With a squeak, the door of the bedroom was pushed open, and Chu Feng stepped in.

It's just a place to sleep, but it's like a conference room, and you can see all kinds of ornaments everywhere, Chu Feng doesn't know how to appreciate them, and he has no interest in these ornaments.

What he was really interested in was the entrance to the secret room hidden here, and he had just discovered through the "Red Detective" that there were several connected secret rooms underneath this room, and there were many things stored in them.

The fourteen princes have already hung up, and those things of his have naturally become ownerless things, and Chu Feng will not be polite.

Continue to walk inside, according to Chu Feng's detection, the entrance to the secret room is under the bed, and it is set up very hidden.

"Huh?"

Before he saw the bed, Chu Feng stopped and moved his nose, and he could smell a refreshing aroma in the air.

The flavor of this aroma is not strong, and if you don't pay careful attention, you may even ignore it.

"What kind of aroma is this, and the smell can calm people's minds. Chu Feng was stunned for a moment, and looked for the aroma.

Soon, he found that the aroma was coming from an incense burner, and a faint white smoke erupted from the mouth of the beast-shaped incense burner, and soon dissipated into the air.

Chu Feng moved his nose again, and his expression became a little surprised: "That's right, it's this kind of aroma, I didn't expect it to have the effect of 'concentrating and calming down'." ”

With this discovery, Chu Feng suddenly became interested, he hurriedly opened the incense burner, and found a "strange fragrance" that was sparkling inside.

It is said to be peculiar because this incense is dark blue and has a twist-like pattern, which looks very peculiar.

"What the hell is this?"

Chu Feng took this piece of "incense" out of the incense burner, put it in front of him and looked at it carefully, he judged that this "incense" was made by the fusion of several materials, and there should be complicated procedures.

"What a waste, to ignite it like this!" Chu Feng extinguished the spark and muttered.

If he had this kind of "incense" before, then those of his students, when they were "concentrating", would not have been so difficult.

In Chu Feng's eyes, this kind of "strange fragrance" is a good thing, which is equivalent to an item that assists in cultivation.

"I don't know where I can get this 'incense'?" Chu Feng found another handful of this strange incense in the wooden box under the incense burner, but he still felt that it was not enough.

This "strange fragrance" is a consumable, so it would be nice to know how to make it!

Chu Feng put away these "strange incense", thought about it, and simply put away the incense burner, and after doing this, he came to the bed.

On top of the bed, a huge animal skin was laid out, which hung down to the ground like a curtain.

The corners of Chu Feng's mouth raised slightly, but as soon as his mind moved, all the things on the bed flew to the side, revealing a wooden bed carved with "Beast Fighting".

The wooden bed was not the point, and it flew to the side, revealing the solid metal underneath.

There are two grooves on the backing board, and if you don't have enough strength, even if you know that there will be secrets below, you can't do anything about it.

It is more appropriate to say that it is a backing plate, but in fact, it is a "cover plate".

Chu Feng walked over, bent down, and personally tried the weight of this "cover", only to hear a strange noise, and the cover was lifted.

"The weight is above four thousand catties, and the protection is so good, it seems that the things hidden below are not simple!" Chu Feng looked forward to it.

The "cover" was fully lifted, revealing a staircase that extended downward, and it was pitch black inside.

Chu Feng found a torch stuck in the wall, and although he had night vision, he still lit the torch, which looked more comfortable.

Holding a torch in his hand, Chu Feng walked down the steps, his speed was not fast, and the red probe kept exerting.

Suddenly—

Chu Feng stopped and looked at one of the steps below, as if he had found something.

"Trap?" Although he was curious about what kind of trap it was, Chu Feng thought about it and forgot it, first to see what good things were hidden inside.

Finally descending to the last step, Chu Feng encountered a total of three traps, all of which he avoided.

"This is really a big deal, it has dug so deep!" Chu Feng sensed, from here to above, it was at least twenty or thirty meters high.

Now the place where Chu Feng is located is a passage, and he can feel a faint wind blowing from inside, that is to say, there is air inside, there may be more than one entrance, and it is possible that this is also a secret passage for escape.

"I don't know how much manpower and material resources it will cost to build such a secret passage?"

Chu Feng sighed at the architectural ability of this world, but his footsteps did not stop, he continued to walk forward, and after a while, he came to the door of the first secret room.

The door to the secret room was made of rock, and the weight was not light, so you didn't have the strength to open it.

Chu Feng smoothly pushed open the door of the secret room, there was a lot of space inside, there were many books, and some of the words were actually written on animal skins or rocks.

Chu Feng didn't learn the words of this world together, he didn't know what kind of books these were here, but since they were hidden here, they must have some value.

Without thinking much about it, Chu Feng directly packed all the books in this secret room and took them away, anyway, the space in the "Nine Xuan Array Tower" was very large, and after bringing it back, it was not too late to study it slowly.

Out of this secret room, Chu Feng continued to walk along the passage inside, about a few dozen meters, and came to the door of another secret room.

From the outside, it looks exactly like the secret room you just encountered, with doors made of rock, and even the size of the doors is strikingly similar.

Chu Feng did not hesitate and pushed the door of the secret room open again.

When he saw the things inside, Chu Feng was stunned for a moment, a wry smile appeared on the corner of his mouth, and he said with some self-deprecation: "Poverty limits my imagination!"

All along, Chu Feng felt that he was very rich in this other world, but at this moment, he suddenly realized that he was poor.

The open space of the secret room was full of "Ka".

That's right, it's "Langka", not "Doulang"!

One "Langka" is equivalent to 100 "Doulang", and it is randomly piled up on the ground in the shape of a hill.

Around this "Langka Hill", there were hundreds of large boxes, and Chu Feng walked over curiously and opened one box at random.

"This ...... This turned out to be 'Ka Jing'!" Chu Feng felt that his breathing was a little short.

"Card Crystal", the highest unit of the world's currency, one card crystal is equivalent to a hundred lang cards, which is equivalent to 10,000 bucket langs!

Oh my God, it turns out that the prince of the empire can be so rich!

Oh my God, Chu Feng has really become a rich man now!
