Achievement system: I am cultivating immortals in the world of martial arts

There is a big rushing river here, with oases on both sides of the river, but further to the west, there is endless desert.

In the desert, there is a huge pyramid a hundred meters high, which is made of huge stones. It is extremely spectacular.

"The triangular building is the end of the treasure map. Maybe the Dark Book is here."

Nie Yin pointed at the pyramid and said.

Tianji shook his head and said,

"I didn't feel any dark aura. Is the Dark Book really inside?"

Nie Yin sneered and said,

"Haha, if that dark aura could be felt, wouldn't you have found the Dark Book long ago?"

"That makes sense. Let's blow this pyramid down and see."

Tianji was ready to take action as he spoke.

Nie Yin stopped her and said in a deep voice,

"If you take action, aren't you afraid that the energy fluctuations will be noticed by the God of Death and Tianshu?

What's more... doesn't the pyramid have a door? "

Following the direction Nie Yin pointed, Tianji saw a door. She immediately blushed and said,

"Well...I'm testing you to see if you can find that door."

I believe you, you are just as stupid as the God of Death said...

Nie Yin cursed, then went down with Tianji and arrived at the gate of the pyramid below.

Their feet stepped on the yellow sand, making a creaking sound. Through the doorway, they came to the ancient stone door.

Nie Yin reached out and pushed open the door. Inside, there was an extremely dark corridor.

The sunlight can only shine two or three meters into the corridor, and the rest of the area is completely dark.

Fortunately, of the two of them, one is a seventh-level saint, and the other is extremely attuned to darkness. They can easily see in a dark place. It makes no difference to them whether it is dark or light inside.

After walking more than a hundred meters inside, they saw a square altar in the middle of the pyramid.

On the altar, there are many ancient and mysterious inscriptions inscribed, which are incomprehensible. In the middle, there is a square stone slab, which is one foot long and twenty centimeters wide. It looks about the size of a book. Fit, embedded in the altar.

From the gap between the stone slab and the altar, there was a wisp of dark breath floating out, blending into the air and disappearing.

"This is the breath of darkness, such a pure breath of darkness, sacred and great, like all the lords of darkness..."

Tianji stretched out his hand, picked up a wisp of dark breath, put it under his nose, inhaled it into his body, and wanted to moan intoxicated.

After a moment, she opened her eyes, looked at Nie Yin, and said,

"Boy, this is definitely the breath of the Dark God Book. I don't believe that there can be anything in this world with such a pure dark breath, a breath even darker than the Dark God Book.

This is the Book of Darkness, the Book of Darkness! "

Tianji was trembling with excitement, unable to conceal the excitement in her heart.

She even wanted to pick up Nie Yin and kiss him hard now.

Unexpectedly, an ant-human race that she casually rescued a month ago could bring her such a big surprise, allowing her to obtain the artifact she wanted and longed for most.

Now, Tianji believes in an old saying of the human race, good things come to you.

Nie Yin also smiled, very evilly, and said,

"Congratulations to Queen Tianji for obtaining the Book of Darkness."

"It's too early to congratulate now. I have to hold it in my hands to consider it as an achievement."

After finishing speaking, Tianji stretched out his hand and placed it on the stone slab. He was about to lift the stone slab and get the dark book underneath.

However, the moment she touched the stone slab, all the runes on the altar immediately lit up.

Those runes emitted strong energy fluctuations, and an aura of destruction appeared.

Upon seeing this, Tianji was shocked and immediately withdrew his hand, and the runes dimmed and the energy fluctuations disappeared.

Tianji looked shocked and murmured,

"Strong energy fluctuations, such a strong destructive aura, but the strange thing is that these energy fluctuations do not attack me, but extend inward. What is going on?"

Nie Yin thought for a moment and then said,

"Do you think this energy wave is not aimed at outsiders, but is intended to destroy the Dark God Book when outsiders take it?"

Tianji was startled when he heard this, and then said,

"There is a possibility, but...who did this? He hid the Book of Darkness here so that no one could take it, and he also created a seal like this to seduce people to come and get it.

It would self-destruct as soon as he took it. Since he didn't want anyone to take it, he could just destroy the Dark God Book. Why wait for someone to find it before destroying it? Are you teasing me?

If you are reluctant to let the Dark God Book appear in the world, then just set up a seal to the outside world. Why leave a bullshit treasure map for it?

I really can’t understand what the person who did this was thinking! Grass! "

Nie Yin's head was full of black lines and he said,

"You are making things complicated. Is it possible that the person who set this up in the first place simply wanted to test whether the visitor is qualified to take away the Book of Darkness?"

"Test me? Is he qualified to test me? Is he worthy? The destructive energy in this is 10,000 years too early to hurt me."

"But destroying the Dark Book is enough."

"Okay, let's not talk anymore. Since it is a test, there must be a way to pass it. Isn't it just some runes? Put a lock on the door and think that I can't come?"

After speaking, Tianji's pupils suddenly became deep, as if there were endless stars in them.

"Tianxiong, connect the computing system on the Fallen to me and activate the most powerful computing system to calculate this rune!"

"Yes, Queen."

Tianxiong in outer space immediately controlled the system to connect to Tianji.

With the help of the spacecraft's calculations, Tianji looked at the runes in front of her and quickly started calculating.

In her eyes, all the runes in front of her flew up and appeared clearly in front of her eyes. Every rune was clearly visible, and the rules, energy, functions, etc. contained in it were all clearly analyzed by Tianji.

It only took Tianji three minutes to complete the calculation. Then, she stretched out her hand and quickly moved the runes. After moving more than thirty runes, the rune seal formation finally collapsed completely and turned into A bunch of useless things.

The light of those runes disappeared, and the stone slab on the altar slowly rose automatically.

The stone slab gradually came into the air, and what flew up was a black book one foot long, twenty centimeters wide, and five centimeters thick.

There is a black skull on the book, and the skull's eyes are emitting an extremely dark and strange light...
