Pick up an assassin as a wife

"Would you like to visit the underground library?" the great elder asked.

Li Tian's expression was startled, and he looked at 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 us from going outside the library. I think as the deputy dean of the library, you are qualified to go outside the underground library. Went to visit!" the great elder said.

Li Tian did not refuse again.

The underground library is located underground. This may sound like nonsense.

Well, this is bullshit.

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

There are two staircases on the east and west sides of this library building. These two staircases are pedestrian stairs leading to the upper floors.

In the south of the library, behind Li Tian's residence in the library, there is a staircase hidden behind several rows of bookshelves.

This staircase is built downwards, and these rows of bookshelves completely block the staircase, so if you weren't a thoughtful person, who would have thought that there is a downward staircase here.

The library on the first floor is open to students from lower colleges. On weekdays, there are only a few lower colleges here.

These bookshelves are made of a specific material and placed according to a magical rule. Even if ordinary people want to push open these bookshelves, they are completely unable to do so.

Maybe you are thinking that there should be some mechanism here.

But the fact is that there are no mechanisms here at all. If you want to go down the stairs, you can only push the bookshelf.

According to the great elder's description, there are at least four to five hundred such layouts on this floor of the library. Even if the elders in the Netherworld Academy know that there is an underground library, they may not be able to find it.

Even if they could find it here, they might not be able to push the bookshelf open. Even if they could push the bookshelf open, they wouldn't be able to enter the underground library.

The elder pushed open the bookshelf, and Li Tian followed the elder down the dark stairs.

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

The corridor was dark and there were no emergency lights.

And this blackness is really black, spreading like ink.

"Elder Li Tian, ​​have you noticed the difference here? Yes, in the outside world, even if the darkness is so dark that we can't see our fingers, to us cultivators, it is still like daylight. However, the darkness here is real It's dark, but you don't have to worry, the stairs are quite neatly built, and there aren't any clutter here, so just feel free to go!" the great elder said.

Li Tian nodded slightly, but suddenly remembered that nodding in this darkness was useless, and then said: "Thank you, Great Elder, for the reminder!"

The stairs continued to go down, and he didn't know how long he walked. When Li Tian counted more than 900 steps, a faint red light gradually appeared in front of his eyes.

As they continued walking down, the red light in front of them became clearer and brighter. Gradually, Li Tian and the elder could see the corridor clearly with this red light.

Continuing to go down, there are a total of 999 steps. Before finishing the steps, Li Tian already felt a warm feeling.

The great elder was no longer explaining, and Li Tian was no longer interfering.

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

"Right in front!" the great elder said.

When he said this, the great elder's face showed a sacred expression involuntarily.

After walking through the thousand-meter corridor, my eyes suddenly opened up.

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 sight in front of him.

This is not a stone door. To be precise, this stone door looks more like flowing magma.

This is not magma. If it were magma, how could it condense into such a form?

Li Tian could feel the fluctuations of spiritual power on the magma stone door. These spiritual powers contained huge energy. When he pressed his hand on the red stone door, a hot feeling would immediately pass through the stone door, but it would not hurt. The skin on Li Tian's palm, but a powerful repulsive force immediately came from it.

Li Tian's body was instantly ejected and flew out. If the Great Elder hadn't caught Li Tian quickly with his quick eyes and hands, Li Tian would have been ejected directly out of the one-kilometer corridor.

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

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

Seven keys?

Li Tian thought of a certain anime from the Japanese island country, where he could summon the dragon by finding all seven dragon balls.

Li Tian looked at these keyholes and asked, "Is it possible that no one in Netherworld Academy has ever opened the door to this underground book since that powerful man ascended during the day?"

"Yes! In the history of Netherworld Academy, some people have opened this door, but after opening it and entering this door, those people never came back!"

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

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

Only then did Li Tian notice that the keys in his hand were in order, just like the stars on each dragon ball on the seven dragon balls. There were some threads on the key. Only if these threads corresponded to the threads on the stone door could the key be inserted. go.

If Li Tian put the key given to him by the elder into the corresponding keyhole, the key could be turned, but it could not open the stone door.

"Don't work in vain. You must find all seven keys to open the stone door! Leave this key in the keyhole now and don't move it. You will see a miracle after a while." The great elder said.

Li Tian listened to the elder's words and 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 leather bag he carried with him, and took out a stone box from the leather bag.

Seeing the stone box shining with red light, 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 already appeared in the stone box.

"Isn't it magical? Is it scary? It's so magical, it's so scary!" The great elder thrust the stone box into Li Tian's hand and said seriously: "Do you understand something now?"
