"Do you want to visit the underground library?" asked the Great Elder.

Li Tian was stunned and stuck in the Great Elder in confusion.

"Don't get me wrong. We only have two keys, and no one can enter the underground library, but this does not affect our going outside the library. I think as the vice president of the academy, you are qualified to visit the outside of the underground library!" said the Great Elder.

Li Tian did not refuse again.

The underground library is located underground, which sounds like a nonsense.

OK, that's all nonsense.

However, if the immortal elder brought Li Tian to this underground library, Li Tian would never find the entrance to the underground library.

This academy building has a staircase from east to west. These two staircases are pedestrian staircases leading upstairs.

And to the south of this academy, that is, behind Li Tian’s residence in this academy, there is a staircase hidden behind several rows of bookshelves.

Because this staircase is built downwards, these rows of bookshelves completely block the staircase, so if you were not interested, who would have thought that there would be a downward staircase here?

The first floor academy is open to students of lower-class colleges, and there are only a few lower-class colleges here on weekdays.

These bookshelfs are made of a specific material and are placed with magical rules. Even if ordinary people want to push open this bookshelf, they are completely impossible.

Maybe you will think about what mechanism should be here.

But the fact is that there is no mechanism here at all. If you want to walk down the stairs, you can only push open the bookshelf.

According to the description of the Great Elder, there are at least four or five hundred such layouts in this academy. Even if the elders in the Netherworld Academy know that there is an underground library, they may not be able to find it here.

Even if they can find this place, they may not be able to push the bookshelf. Even if they can push the bookshelf, they will not be able to enter the underground library.

The Great Elder pushed open the bookshelf, and Li Tian followed the Great Elder down the black stairs.

The bookshelf quickly returned to its original state after Li Tian and others entered the stairs.

There was a dark and clean corridor, and there was no emergency light.

And this kind of black is really black, spreading like ink.

"Elder Li Tian, ​​have you discovered the difference here? That's right, in the outside world, even if the darkness cannot see the five fingers, it is still like daytime for us practitioners. However, the darkness here is really dark, but you don't have to worry. The staircase is built quite neatly and there is no debris here. Just leave with confidence!" said the Great Elder.

Li Tian nodded slightly, and suddenly remembered that it was useless to nod in the darkness, so he said, "Thank you for the reminder of the Great Elder!"

The stairs kept going down, and I don’t know how long I walked. When Li Tian counted to more than 900 levels, a faint red light gradually appeared in front of him.

Continue to walk down, the red light in front of you becomes clearer and brighter. Gradually, Li Tian and the Great Elder can rely on this red light to see the corridor clearly.

Continue to go down, there are 999 steps in total. Before he finished walking the steps, Li Tian could already feel a warm feeling.

The Great Elder is not explaining, and Li Tian is not asking about it.

After walking the steps, a corridor with a length of more than kilometers appeared in front of me. The corridor was red, and the red light was at the end of the corridor.

"Just ahead!" said the Great Elder.

When he said this, a sacred expression appeared on the face of the Great Elder involuntarily.

Walking through the 1,000-meter corridor, my eyes suddenly became clear.

A magnificent stone door appeared here, and the red light in the corridor was released from this stone door.

Li Tian was shocked by the scene in front of him.

This is not a stone gate. To be precise, this stone gate looks better like flowing magma.

This is not magma. If it is magma, how could it be condensed into such a form?

Li Tian could feel the fluctuations of spiritual power on the magma stone gate. These spiritual powers contained huge energy. When pressing his hand on the red stone gate, a hot feeling would immediately pass through the stone gate, but it would not hurt the skin on Li Tian’s palm, but then a powerful repulsive force would be heard.

Li Tian's body was instantly bounced out. If the elder hadn't grabbed Li Tian quickly, Li Tian would have been bounced out of the corridor of that 1,000 meters.

"Li Tian, ​​it's useless. There is no way to open this door except with a key!"

"Did you see it? Here...and here... these are key holes. Unfortunately, there are seven holes in this stone wall, and we only have two keys."

Seven keys?

Li Tian thought of an anime from the Japanese Island Kingdom, and he could summon the dragon by finding seven dragon balls.

Li Tian looked at the keyholes and asked, "Has no one ever opened the underground book collection door since the powerful man ascended in the sun?"

"Yes! Someone has opened this door in the history of Netherworld Academy, but after opening and entering this door, those people never came back!"

A smile appeared on the corner of Li Tian's mouth, and the key given to him by the elder was shaking in his hand, with an expression of disbelief on his face.

"I know you don't believe me, so I'll show you something magical! Insert the keys I gave you into these key holes in order, and you will know what will happen after a while!" said the Great Elder.

Only then did Li Tian notice that the keys in his hand were in sequence, just like the stars on each dragon ball on the Dragon Ball. There were some threads on the key. These threads could only be stuffed into the key if they correspond to the threads on the stone door.

If Li Tian stuffed what the Great Elder gave him into the corresponding keyhole, the key could turn, but he could not open the stone door.

"Don't be futile. You must find seven keys to open the stone door! You can leave this key in the keyhole now, don't move, you will see a miracle in a while." said the Great Elder.

After hearing the words of the Great Elder, Li Tian left the key in the keyhole. After about ten minutes, the key suddenly disappeared.

"This... how is this possible? How could the key disappear?" Li Tian asked hurriedly.

The Great Elder smiled and opened the skin he carried with him, and took out a stone box from the skin.

Seeing this stone box with red light shining all over, Li Tian seemed to understand something.

Sure enough, after the Great Elder opened the stone box, Li Tian saw that the Great Elder's key had actually appeared in the stone box.
