I, the Emperor of Heaven return

"Teacher, that guy just now has such murderous intent!" Duanmulu also looked at the man in black and secretly called Nie Tian.

"Yeah." Nie Tian nodded and said nothing more.

He was very sure that the man in black just wanted to kill Ning Ziyu.

Fortunately, he reacted in time and walked over directly, otherwise Ning Ziyu would most likely have died at the hands of the man in black without knowing it.

The man in black is very good at hiding murderous intent, but when he wants to kill someone, the burst of murderous intent cannot be hidden.

Although the moment just now was very ordinary, for Ning Ziyu, it was a moment of life and death.

If it weren't for Nie Tian, ​​this little girl would have died again.

Who is this man in black? He dares to assassinate the eldest lady of Wanbao Chamber of Commerce at the auction of Wanbao Chamber of Commerce. It is really arrogant.

"Nie Tian, ​​what are you doing?" At this moment, Ning Ziyu realized what he was doing. Seeing Nie Tian's downcast expression, she couldn't help but ask.

She already knew the names of Nie Tian and others, and knew that Nie Tian and Duanmulu and others had a master-disciple relationship.

She was curious about how Nie Tian could become the teacher of so many people at such a young age.

"Nothing, let's go." Nie Tian smiled faintly and decided to let Ning Ziyu continue to be ignorant.

In Ning Ziyu's current state, it would be better not to let her know that someone is trying to kill her.

"Yes." Ning Ziyu agreed and led the way towards the fifth-floor auction house.

Nie Tian smiled faintly at this time, with a strange curve at the corner of his mouth, and said secretly in his heart: "You'd better not come near us again, otherwise I won't be polite."

The man in black didn't make a move, obviously he was afraid of Nie Tian.

Nie Tian also didn't take action, but he had secretly carved the soul aura of the man in black into the four strange soul stones.

At this time, he could no longer see the trace of the man in black, but he could feel the latter's position at all times through the four strange soul stones.

After a while, Nie Tian and others arrived at the auction house on the fifth floor, and Ning Ziyu entered a VIP room with ease.

Several people entered the VIP room one after another. They had a wide view around them and could completely see the entire auction house on the fifth floor.

"Nie Tian, ​​don't be nervous. We have arrived at the auction house under the supervision of fifth brother. I am completely safe." Ning Ziyu saw that Nie Tian and others were a little nervous, so she couldn't help but laugh and said.

Nie nodded and didn't say much.

This ignorant little girl thought that she was absolutely safe after entering the auction house.

Little did they know that after she entered the auction house, she became even more dangerous!

However, she had good taste and chose Nie Tian as her bodyguard.

"Well, let's take a look first and see what is being auctioned now." Ning Ziyu smiled easily and focused her beautiful eyes on the huge auction table.

"An old voice sounded, and then an old man with white hair and beard walked to the auction table and said loudly.

"Third-level Holy Formation Scroll!"

Holy formation scrolls are very rare even in the holy world, let alone a third-level holy formation scroll!

You know, the power released instantly by a third-level holy formation is enough to kill the powerful Heavenly Mandate Saint Master!

"This third-level holy formation is a scroll of concentration. It is especially suitable for warriors who practice spiritual power. When they practice in the concentration formation, their spiritual power will increase at least ten times faster!" Then, the white-haired old man continued to speak, said loudly.

But his words made everyone feel cold.

"It turns out it's a scroll for cultivating spiritual power. What's the use of it?" The crowd was in an uproar, obviously they didn't like the scroll of concentration at all.

Regardless of whether it is the Holy World, the Realm World, or the Unavoidable World, there are always very few warriors who practice spiritual power.

Therefore, the market for concentration scrolls is not big.

For most warriors, the Concentration Scroll is useless.

Because cultivating mental power is a waste of time, and the improvement of mental power does not directly increase a warrior's combat power.

Having strong mental power only allows the warrior to improve his or her perception, or by practicing some spiritual martial arts, one can launch spiritual shocks.

But practicing spiritual martial arts is even more of a waste of time.

Therefore, very few warriors waste time cultivating spiritual power.

"Hurry up and make an offer. Let's end it quickly." Before the white-haired old man could finish speaking,

"The price quoted for this concentration scroll is one hundred top-grade holy crystals." The white-haired old man looked at the people below and couldn't help but shake his head, but he still said loudly.

But when his voice fell, everyone below started shouting.

"A hundred top-grade holy crystals are too expensive, why don't you go and grab them!"

"That's right. Isn't it just a scroll for cultivating spiritual power? It's of no use at all?"

"Who would spend a hundred top-grade holy crystals to buy a concentration scroll? Are they not idiots?"

Everyone looked impatient and thought the white-haired old man was crazy.

The white-haired old man frowned with a look of helplessness on his face. As expected, none of these people knew the value of the Concentration Scroll.

"Nie Tian, ​​buy this scroll quickly!" At this moment, the Ghost Emperor's voice suddenly sounded in the VIP room, and he seemed very excited.

"Really?" Nie Tian frowned and couldn't help but be stunned.

"Of course! This is a third-level concentration scroll. It will greatly improve your spiritual power! Na Fen said hurriedly.

Nie Tian frowned and nodded slightly, but he looked embarrassed.

He had just arrived at the Holy Realm and had nothing. He didn't even know what one hundred top-grade holy crystals meant.

"Miss Zi, is one hundred top-grade holy crystals expensive?" Nie Tian's eyes darkened and he looked at Ning Ziyu and asked.

"Have you only seen holy coins and not holy crystals?" Ning Ziyu was stunned for a moment, then laughed helplessly and said, "Holy crystals are big currencies. It's normal that you haven't seen them. Let me tell you, one low-grade holy crystal is equivalent to 10,000 holy coins; one medium-grade holy crystal is equivalent to ten low-grade holy crystals; one high-grade holy crystal is equivalent to ten medium-grade holy crystals; one top-grade holy crystal is equivalent to ten high-grade holy crystals."

"So, one hundred top-grade holy crystals are equivalent to 100,000 low-grade holy crystals, which is 1 billion holy coins."

Speaking of this, Ning Ziyu raised her eyebrows and said, "People like you who have only seen holy coins can't understand the concept of one hundred top-grade holy crystals."

Obviously, she regarded Nie Tian as a poor man.

"I want to buy that scroll." Nie Tian frowned and said lightly.

"What?" Ning Ziyu was stunned for a moment, thinking that she had heard it wrong.

"I want to buy that scroll." Nie Tian said it again.

"Are you crazy?" Ning Ziyu's beautiful eyes trembled, and she shouted: "Do you know how much one hundred top-grade holy crystals cost? Even if you take out everything on you, I'm afraid you can't get enough for one top-grade holy crystal."

"I don't have holy crystals." Nie Tian frowned, looked straight at Ning Ziyu, and asked: "Can sword crystals be used?"

"Sword crystals?" Ning Ziyu was stunned for a moment, and asked in astonishment: "Do you have sword crystals on you?"

She obviously didn't expect that Nie Tian actually had sword crystals on him!

Of course Nie Tian had sword crystals, and there were a lot of them.

When he left Haotian Sword Martial Arts, Zhong Mingyu asked him to take a lot of sword crystals!

"Are these enough?" Nie Tian took out a space ring, and with a thought, dozens of sword crystals appeared and floated in the air. Suddenly, the entire VIP room was filled with a strong sword aura.

"You...this..." Ning Ziyu looked at the dozens of sword crystals in front of her, her beautiful eyes trembled in horror, her little mouth opened wide and trembled a few times, but she couldn't speak!
