In Li Ziqiu's narration, he mentioned the part about breaking the key, and finally named a person.

Yes, alone!

Moreover, Lin You was really familiar with this person. Although he had never met him formally, he had a deep impression on him.

Without him, this person seems to be impersonating himself after entering the underworld this time!

And the impersonation was so similar that even Guo Rui was almost deceived.

Chu Ke also had a deep impression on that person.

Face Changer!

A bastard who pretends to be himself, looking for students everywhere, and launching sneak attacks.

Of course, he may not only impersonate himself, there may also be other people, including some well-known students, who may be his options.

The most important thing is... the opponent can also summon sleep-inducing monsters, and the summoned sleep-inducing monsters are particularly powerful in causing sleep.

It has stronger penetrating power against soul barriers.

According to Lin You's guess, this person may be related to Instructor Jia, or else it may be the work of the master of the magic field.

No matter which one it is, there is only one purpose, and that is to make these students miserable.

But now it seems that it is not only a trouble, but also serves as the key.

The key to the palace gate is with the Face Changer!

At this time, thinking back to the ever-changing graphics on the gate, Lin You knew clearly that they had something to say.

However, this hint is somewhat useless. Just looking at the changing graphics, who would think of the face-changing man?

It’s better to be misled!

Maybe... they are just trying to mislead you. Do you have any ideas?

At this point, I have read several fragments of this book.

Lin You frowned slightly and murmured: "The face-changing person... is also a trouble!"

Let's not talk about how difficult it is to seize the key from the other party. Just trying to find the other party is probably strenuous enough.

But if we can successfully get the key and open the palace, we can liberate most of the sleeping people in one fell swoop.

In addition, according to the book, those super black star sleeping monsters are just tributes. Once the door is opened and those guys rush in, what will happen?

Will it really turn into nourishment for 'that person' invisibly?

‘That one’ himself lives in the palace?

Probably not. If that were the case, students like them would simply not be able to liberate the sleepers in the palace.

The owner of the magic field is a bit of a trap, but it doesn't go as far as giving them unanswerable questions.

After thinking for a while, Lin You thought no more.

You must find a way to find the face-changing person, but not now.

Now go out, although because of the relationship between the two Noble Phantasms, you don't have to worry about being able to break through the encirclement, but where can you find the face-changing man?

Trying your luck everywhere like a headless fly is obviously a waste of time.

Let's continue reading first and see if we can find more clues.

Besides, there is a door ahead!

The first door is the training room, the second door is the library, what about the third door?

Maybe it’s a treasure trove!

If it is true, then it will be posted, but I don’t know how many slashes are needed to open it this time.

According to the previous rules...three ways?

It's a bit expensive, but it's acceptable. After all, there are more slashes now, four!

Um?

Suddenly, Lin You's eyes moved. What more?

At this moment, there were six slashes on the direction paper.

There are two more!

This means...two more sleeping houses have been liberated.

After calculation, the number of liberated ones reached ten!

This progress is not too fast!

You know, if the sign on the door of the side hall is correct, the total number of sleeping rooms is only fifteen...ten, which is already more than half!

There are still five buildings left to complete the task of liberating all the sleeping houses. It’s not easy!

How long has it been since now?

Since the concept of time is almost lost in this underworld, Lin You's senses indicate that only three days have passed at most.

There is still a long way to go before the teleportation channel is opened.

In three days, ten sleeping houses were liberated. If the time is correct, it would be really amazing.

After sighing for a while, Lin You quickly retracted his attention, found a book again, and started reading.

Reading is important!

There are so many books here, but Lin You didn't intend to finish them all. That was just a dream.

He only sees valuable things!

Yes, after reading the books for so long, Lin You gradually developed a subtle feeling for these books.

Only books with this kind of feeling may be valuable books.

The previous books were all like this.

Obviously, this is also a setting of the magic field, or a reward.

A reward for those readers who don’t listen to books outside the window and are immersed in books!

After the feeling emerged, when I went to choose books, the options were reduced by 90%!

And the more you look at it, the more obvious the induction will be. At that time, it is likely that you can further screen.

Because of this, Lin You could be patient, otherwise, he would have opened the next door long ago.

…

While Lin You was peacefully working as a scholar, five sleep-inducing monsters had already gathered outside the palace.

At this moment, everyone seemed extremely restless and kept banging on the door. This had been going on for an unknown amount of time.

Previously, they failed to stop a few prey and allowed them to hide in the side hall. Without a target, they had no choice but to use the gate to vent their anger.

But after venting for a long time, there was still no result. Finally, three of the monsters roared each other, and after giving the door a final heavy blow, they suddenly turned around.

No more!

It's not like they really have no brains... well, they really don't have any brains, otherwise they wouldn't have been venting for so long to a door that couldn't be opened.

But no matter how stupid you are, if you do stupid things for a long time, you will realize that something is wrong.

At this moment, he suddenly set off.

Stop hanging around here and prepare to take the initiative to search for prey!

There is a lot of risk involved in intercepting people here, and they understand this clearly.

It’s always frustrating to watch the cooked duck fly away!

It's better to take the initiative and see if they can catch some lost prey. Although for those targets that cannot be sensed, they are just trying to catch a blind cat, but what if they encounter it?

Now, this is the idea.

However, not all of them, there are still two who are still banging on the door relentlessly, as if they are determined not to give up.

These two are naturally the two who arrived later, and now they are following the old path of the giant evil spirits.

They didn't bother to pay attention to the giant evil spirit.

Nonsense, the three of them don't pay attention to each other, let alone the two newcomers.

Now, he moved quickly and left here quickly, leaving only the two sleeping monsters to continue banging on the door.

But in fact, giant evil spirits are not the only ones wandering in the wilderness at this time.

Every liberation of a sleeping house will provoke a super black star sleeping monster.

And now, ten sleeping houses have been liberated, and the number of monsters is naturally ten, correspondingly!

Out of the ten, there are two banging at the door, but there are eight wandering around!

No, the only ones really wandering around were the three giant evil spirits, and the remaining five still had goals.
To be continued...
