The echoes are heard.

There is an empty place behind it.

In other words, the wall is actually hollow.

"How to open the channel?"

Si Nanyan also asked.

Upon hearing this, Qin Wuyan thought about it.

"What mechanism should it belong to? Second Senior Sister, take a look!"

For these things.

Qin Wuyan is not very good at it.

Let me leave it to my second senior sister He Wenya.

Hearing words.

He Wenya also nodded slightly.

Then walk to the wall.

I checked carefully.

It's fast, but very careful.

"It's indeed a mechanism, but it's a bit difficult to open it!"

He Wenya said.

Upon hearing this, Qin Wuyan and others were also curious, "How can we open it?"

"Those reels need to be placed in the right position and through the weight to open!"

He Wenya pointed to the scrolls not far away.

Upon hearing this, Qin Wuyan and others were also stunned.

That is to say.

To pass this channel, those scrolls are also required.

And it can't be taken away.

"Where is the pill?"

What Mo Siying cares more about are those elixirs.

If the pill needs to be placed somewhere.

Wouldn't that be a big loss?

"The pill doesn't seem to be needed, and not all exercises need it."

He Wenya shook her head.

Then walk to a stone position.

Push it hard directly.

The stone was pushed away in an instant.

Several scrolls were exposed.

But the above are all empty.

"The three empty spaces on the left need to be placed with the thunder attribute, the earth attribute and the fire attribute!"

He Wenya looked at it before saying.

"What about the four on the right?"

Qin Wuyan asked.

"The four on the right are Fenghuo Shuimu's spiritual skills!"

He Wenya replied.

Hearing this, the few people nodded.

"Look for it quickly!"

Qin Wuyan said.

Then everyone started looking for it separately.

Soon, Si Nanyan found a fire-attributed technique.

Just as I was about to put it on.

He Wenya suddenly spoke, "Sister Sister, wait a moment, if I guess correctly, the three attributes of thunder, earth and fire should correspond to the upper, middle and lower levels of the three levels. The position of fire is at the bottom, and the yellow level of low-grade skills are required!"

"The Yellow Grade Lower?"

Si Nanyan looked at the scroll in his hand.

Yellow-level medium-grade fire attribute exercises.

"What about the four on the right? They probably aren't the third grades of the upper, middle and lower grades, right? Second Senior Sister!"

Mo Siying also asked.

There are four positions on the right side.

It's definitely not the third grade, right?

"It should be the third grade of the upper, middle and lower grade, plus a roll of spiritual skills with the peak of wood attributes!"

The one who answered the question was Qin Wuyan.

If it is not the third grade of the upper, middle and lower grade, one must be collected.

That's the peak.

"Yes, the junior brother is right!"

At this time, He Wenya nodded as well.

"What? Peak...How to find this?"

Mo Siying suddenly felt a little helpless.

If it is the third grade of the upper, middle and lower grade, it is easy to say.

Because they will be marked.

But when this peak is said, there is no mark at all.

There is even no peak at the level.

It's just because it's too strong.

It is only jokingly called the peak.

So you need to find out the peak wood attributes of the yellow-level and put it on.

I really don’t know what method to distinguish it!

This is simply too difficult!

Upon hearing this, Qin Wuyan was also a little helpless.
Chapter completed!
