"Is this person poisoning Senior Sister Yunxi?"

Should I go out and stop him?

Just when Yu Feng hesitated to go out to stop it, suddenly, he seemed to feel a familiar aura in the other party's body.

Even the red fire in his body began to move.

This is...... What's going on?

That breath is, the inner breath of the red fire?

No, to be precise, it was the inner breath of the red fire before the ascension, and the red fire was not pure enough.

When Yu Feng wanted to concentrate and try to remember this aura, the aura on the black shadow's body suddenly disappeared again.

As if it never existed, only the red fire inner breath that was surging in the body proved its existence.

At this time, the black shadow seemed to have finished the hands and feet that should be moved, and I saw him return the things that he had just moved to its original position, and then slowly withdrew from the Dan room.

Yu Feng quietly followed behind him and also came out of the Dan room, wanting to follow him to see who he was.

But I didn't expect to follow not far away, and disappeared from a corner of the school palace.

Lose someone.

Who the hell is he? Why do you also have the inner breath of the Red Fire?

Yu Feng suddenly had some ominous premonitions in his heart, although the black shadow fled towards the outside of the Xue Palace, but judging by his previous familiarity with the Xue Palace and the Danfang, it might be a spy in the Xue Palace.

He could be sure that the black shadow was not Lu Feng, nor was it the person who had attacked him before.

Moreover, the black shadow was obviously very familiar with the general environment of the School Palace, and even knew Zuo Yunxi's usual living habits.

It is very likely that the black shadow is lurking in the school palace.

This Taiyi Dao Sect is really Crouching Tiger, Hidden Dragon!

Back at Danfang, Yu Feng picked up the teacup that the black shadow had moved just now, looked at it carefully, and sniffed it with his nose.

Yu Feng, who is proficient in basic pharmacology, judged that this should be some kind of chronic medicine that can paralyze nerves, and the amount is small and not easy to detect.

And it also contains a small amount of internal breath surge, which looks like it is carefully prepared.

This medicine can be taken in moderation to help you sleep, but once you take a certain amount of it, it will produce a stage of nervous trance, and even paralysis.

According to this dose, at most seven days, the user will have obvious nervous trance and is unable to resist.

That is to say, after seven days at most, the various sleeping dragons and phoenixes hiding in the Taiyi Dao Sect will be dispatched collectively.

It seems that there is not much time left for yourself.

Cleaning up the medicinal powder in the teacup, Yu Feng was not in the mood for alchemy.

Out of the Dan room, he planned to go to the library of the Taiyi School Palace to have a look, after inquiry, Yu Feng knew that his heart and mind, the ultimate goal, Taiyi Danhuo was hidden in the library pavilion.

It's just that the library is heavily guarded, and not ordinary people can enter it.

However, Yu Feng only knew that the corresponding conditions had to be met to enter the Library Pavilion, but he didn't know what they were.

The purpose of tonight's trip is to find out what that condition is.

As for breaking in or sneaking in, forget it.

Yu Feng knew that with his current strength, it was not impossible, but it was difficult.

While thinking, Yu Feng had already come to the library not far away.

He didn't just walk in to test it, but hid in a corner to observe the shift time of the guards at the door.

Taiyi Danhuo is so important to be guarded by the School Palace, there will definitely be a corresponding prohibition on its own alarm.

After getting the Danhuo, he will definitely be surrounded and intercepted by all sides, so he must familiarize himself with the layout in advance and set a perfect escape route by himself.

In the distance, a cultivator was excitedly holding something and running towards the library pavilion.

"I've passed the assessment, I've passed, let me in."

The man walked up to the gatekeeper and handed the token and a piece of paper to the gatekeeper to look at.

"Well, no problem, congratulations to the junior brother for passing the assessment and being able to enter the Library Pavilion to seek a higher level of Dan Volume."

"It's an hour, and it must come out within the specified time, otherwise the junior brother should understand the consequences."

When the cultivator heard this, his expression was shocked, as if it was the first time he had heard about this, so he asked.

"This senior brother, the junior brother entered the library for the first time, and he didn't know anything about the rules inside, so he asked the senior brother for guidance."

The disciple coaxed his hands and asked.

"You'll know when you go in, I'm just reminding you that it's best not to exceed the hour, otherwise there may be unforeseen consequences."

"I understand, thank you for your advice."

The disciple said yes and walked in.

In the corner, Yu Feng frowned and raised his eyes to look at the large library.

Unforeseen consequences? What would that be?

Yu Feng was a little curious, but he obviously couldn't know it immediately at this time, and he planned to go back and ask Zuo Yunxi.

After squatting for about half an hour, finally not far away, two disciples who yawned at a discount came to take over.

Yu Feng silently remembered the time.

Yu Feng silently calculated in his heart, and squatted in place until the second class of disciples rotated time, and then quietly withdrew and returned to live alone.

After returning to living alone and closing the door, Yu Feng began to sort out his thoughts.

When the first shift is ugly, it is about two o'clock in the evening, and the gatekeepers will take over the shift when they intersect with the ugly time.

At this time, the new gatekeeper will have a period of chaos and reduced concentration, and this is the most suitable time to make some small disturbances.

You can take advantage of this time to sneak out of the library pavilion, and if you encounter an accident and don't quit at the first time, you can only wait for the second shift after an hour.

……

On the second day, early in the morning, Yu Feng got up and prepared to go to the Danfang to pack up and sort out the medicinal materials.

As a Dantong, these things are necessary.

However, when he opened the door, he saw a miscellaneous disciple silently cleaning the courtyard with his head down.

Yu Feng felt that this figure was somewhat familiar, and after walking in and confirming that someone was coming, the corners of his mouth suddenly showed a touch of playfulness.

"Yo, isn't this Senior Brother Lu Liu, why did you get up so early to be on duty."

As soon as Lu Liuyi heard Yu Feng's voice, he subconsciously wanted to yell, but when he looked up, Yu Feng in front of him already seemed to be a different person.

I saw that he was wearing a brocade white practice uniform, with a dark purple threaded horn belt around his waist, and a token that belonged to Zuo Yunxi was hanging on it at will, and his black hair floated with the breeze, revealing his unique aura.

Only then did Lu Liu react, this Yu Feng was no longer the Yu Feng of the year, and now he had officially moved into the School Palace, completely getting rid of the lowly status of miscellaneous servants.

"Don't dare to be, don't dare to be, Senior Brother Yu Feng is now a disciple of the Academy Palace, and he really can't be called that." Lu Liu lowered his head, not daring to look up at Yu Feng at all.

"What's not to dare to be, didn't you often call yourself that before."

Yu Feng smiled.

"Don't forget to clean up the room for your junior brother in a while."

"Okay......" Lu Liu's face was ugly at this time, but due to his identity, he had to bow his head again.

Just when Yu Feng was about to give up making fun of Lu Liu and was about to go to the Danfang to sort out the materials.

The system prompt in my ear rang again.
