When the morning bell of the clock tower rang again, the students who were preparing for class realized that their normal life seemed to be coming back.

The uniformed soldiers who were everywhere in the academy yesterday have disappeared without a trace today. It's as if the alert mode of the previous days never existed.

It's just that the infirmary and other places are cordoned off, and some workers in the uniforms of the Imperial Construction Corps are clanging in the fenced field.

In the course of the whole incident, the relevant leaders have submitted a written report to Emperor Marenor, and the list of other victims and the related aftermath work are also being carried out in an orderly manner.

Phyllis and Lucia's personal belongings were confiscated to follow up on deeper leads. The death of the classmates around him made these students sad for a long time.

Time will dilute everything, though.

In the fourth cafeteria, Su Wen and Ellie were sitting around a table, enjoying their breakfast. The three girls did not lose their food because of the low mood brought by last night, but felt hungry because of the strenuous exercise.

Ellie, in particular, eats almost as much as five Barrot and Yumi combined.

But in the eyes of the two, this is not a strange thing.

Students start classes an hour earlier than the regular faculty and staff start work, so Barlot and Ellie leave the cafeteria after eating. Su Wen and Yumi were left behind, still enjoying a leisurely morning tea.

Su Wen tasted this very flavored tea slowly, but found that Yumi's demeanor seemed not so comfortable, as if he was struggling with something.

"Is there anything you'd like to say?"

"Ahh......h......h

"Yes. ”

"If Teacher Su Wen is too busy, then forget it, I'll try again...... Ah, can you?" Yumi didn't seem to listen to Su Wen's answer at all, but read the draft in her heart by herself, and when she reacted, she realized that Su Wen had agreed to her request.

"When?"

......

The two went to the old library building.

Compared with the new building, there are far fewer teachers and students here, and the entire area is more than four times the size of the new building.

Because of the murder, the library went on strike for a day, so almost all library staff today are at work.

In the name of sorting out the books, Yumi took Su Wen to turn left and right in the old hall and came to a hidden basement.

"There are some remnants stored here, and few people come, according to the clues I have gotten, the entrance is here......"

Yumi said as he fumbled to turn on the lighting in the basement, which was still the same old hedron lamp, which was much less efficient than the current generic models.

"Do you know your teacher's situation?"

"I don't know much...... Yumi's eyes fell on the bookshelf, as if he was looking for some mechanism: "I only know that the teacher is a person from hundreds of years ago, and in addition to leaving that inheritance, more things are in this treasure house...... Ah, I found it!"

Yumi pulls out a book, then reaches into the bookshelf and hits a switch.

A stream of mana sparked from the bookshelf to the floor, a faint stream of visible mana that carved a square shape across the floor, and then the wooden square floor creaked open a crack, revealing a passage that led to the depths.

"Isn't this just open?" Su Wen was a little strange.

"No, it's just the entrance...... There is also a gate below. Yumi pushed the floor open, revealing the full view of the passageway.

At the entrance, a stone door stopped in front of the two of them. The stone gate is tightly stuck in front of the passage, and the surface of the quaint stone slab seems to have been carved with a simple smiley face symbol with a sharp knife rather casually.

What's the fun about that?

Yumi stood in front of the slate, her hands wrapped around a purple shimmer, and tried to push it, but the slate didn't move.

"I almost tried my best, but I couldn't push it, so I didn't dare to make any bigger moves......

With that, Yumi stepped back and scattered the purple light.

Su Wen came to the entrance and checked the entrance.

Sure enough, the slate fit so tightly that it barely had a thin blade to fit in, unless it destroyed the surrounding floor. But this kind of brutal destruction is likely to damage the structure inside, maybe people do not enter, but it will increase the obstruction.

Su Wen also pushed, but there was no response.

Then he put his palm on the slate again, and with the ability to "hold down E to drag the object", he pulled the slate outward—

I saw a slight trace of dust shake down, and the entire stone slab was pulled out by Su Wen without any hindrance, and then placed next to it.

Su Wen couldn't help but turn his head to look at Yumi.

Yumi was stunned on the spot.

Why didn't I think of Ra??wow...... It's over, will Teacher Su Wen think I'm stupid......

However, Su Wen didn't care too much, but enabled the night vision function and probed the situation inside. As Su Wen could see, the entire passage was extending downward, and Su Wen could barely reach the bottom at a glance.

Yumi also looked at it curiously, her eyes flashing with purple light, and she seemed to have the ability to see at night. After looking, Yumi turned his head and said to Su Wen with some hesitation: "I can't see the end at a glance...... Are we ......"

"Don't be afraid, there's no danger. ”

Su Wen comforted Yumi, and from his expression, Yumi could see curiosity. In other words, Su Wen wanted to take a look.

Hawkers, even if there is danger, in Su Wen's eyes, it is actually nothing.

“......”

Yumi was still a little hesitant.

"Then I'll go down first, if I encounter something good, I'll take it as a respect?" Su Wen didn't say anything more, and jumped in directly.

"Huh?" Yumi was startled, stood at the entrance with some embarrassment, thought about it, and shouted inside: "Then Teacher Su Wen, you have to be careful......

After shouting, a faint echo came back from the passage.

That's fine......

But suddenly, Su Wen came out of the passage again, grabbed Yumi's hand without saying anything, and dragged her into the passage.

"You keep up with me! This is your teacher, not my teacher! Will your teacher hurt you?"

"Ah!——————h

Throughout the passage, Yumi's mournful cry reverberate.
