Today, Yitian ascended to the second floor of Tenglong Pavilion, which immediately attracted the attention of many people nearby, and everyone stared at Yitian's figure with envious eyes.

The door to the second floor of the Tenglong Pavilion was closed, and when Yitian came to the door, a deep voice came into his ears.

"Come in, Nangong Feiyu. ”

The voice was old and low, but it was full of majesty, and people did not dare to disobey it.

Yitian pushed open the door, and the squeaking sound was particularly harsh.

Because the doors and windows are closed, the light inside is extremely dim, and the moment the door opens, an unknown world seems to open at this moment.

Standing outside the door, Yitian looked inside the door and saw a gray figure sitting in it, with his back to the door.

Looking at the man, Yitian slowly walked into the house, the heavy wooden door closed automatically, and the light immediately disappeared.

In the gloomy environment, Yitian's brows furrowed, and he stopped a few feet away from the gray shadow, silent.

For Yitian's arrival, the gray shadow on the ground seemed very calm, and said indifferently: "You have two chances, you can choose two magic books. You can pick one today and come back next time. You can also choose two books at a time today, and it's up to you to decide how to choose. ”

Yi Tian looked at the situation on the second floor of Tenglong Pavilion, which was a closed black room, with a total of eighteen bookshelves, and each bookshelf contained six cheats, a total of one hundred and eight cheats.

Of these, sixty-four cheats have already been taken, and forty-two cheats remain.

These cheats are placed in a wooden box, and people can choose at will, but they are not allowed to open the wooden box, so they can't see what kind of tricks are inside.

In addition, there is an invisible seal on each wooden box, which can isolate the intrusion of detection waves and prevent cheating, as a sign of fairness.

In this case, it's all a matter of luck.

Knowing this, Yitian said softly: "I plan to choose two books at a time." ”

Gray Shadow said coldly: "Yes." If you have a stick of incense for a while, and if you haven't chosen more than one stick of incense, it will be deemed to be automatically abandoned. ”

Yitian said: "Thanks for the reminder, I'll start now." ”

Moving his footsteps, Yitian carefully paid attention to the wooden boxes on the bookshelves, and found that the appearance of each one was exactly the same, and there was no obvious difference.

On the surface, Yitian was observing these wooden boxes, but in fact, Yitian was secretly analyzing the invisible seals on each wooden box.

This seal is a kind of consciousness seal, formless and colorless, but it can prevent the invasion of probing waves.

There are a total of forty-two wooden boxes on the second floor of the Dragon Pavilion, and the seal on each wooden box is different, which makes Yitian quite surprised.

According to Yitian's analysis, this so-called seal is actually an invisible enchantment set up on the periphery of the wooden box.

This kind of enchantment will not affect the opening of the wooden box, but it can prevent the invasion of the detection wave of the Martial Venerable-level master.

The key to this lies in the oscillation frequency of the enchantment and the oscillation layer.

In addition, who set up these seals, and whether it will have anything to do with the gray shadow, this must also be clarified in advance.

According to rumors from the outside world, the guardian of the second floor of this Tenglong Pavilion is named Nangong Xiaotian, and he is a martial emperor-level powerhouse.

If this statement is true, then the gray shadow in the house is Nangong Xiaotian, who has amazing strength.

Under normal circumstances, the martial artist of the Nangong family entered the second floor of the Tenglong Pavilion, and any move should not escape Nangong Xiaotian's eyes.

Yitian is now Nangong Feiyu, and he is also a martial artist, if he wants to play tricks under Nangong Xiaotian's nose, he has to be extra careful.

Thinking of this, Yitian reined in his mind and did not emit any Yuan Force detection waves, so as not to be detected by Nangong Xiaotian.

Because of the limitation of cultivation, the frequency of the Yuanli detection wave is limited, and it is absolutely impossible to hide it from Nangong Xiaotian.

But Yitian's consciousness fluctuation frequency is unbelievably high, he can quietly unfold consciousness detection, directly stretch the consciousness frequency, and bypass Nangong Xiaotian's consciousness fluctuation range.

This is something that ordinary people can't accomplish at all, and only geniuses have such abilities.

Shuttling between the bookshelves, Yitian secretly sent out a wave of mind detection, locked on the forty-two wooden boxes, and carried out an all-round detection of this.

At that time, countless information was fed back into Yitian's mind, and after analyzing and calculating, and then adjusting the frequency of the idea detection wave, it was quickly clear what was going on on these wooden boxes.

As Yi Tian guessed, there is an invisible barrier on the outside of these wooden boxes, with a rather strange oscillating frequency.

It's weird, but there's a lot to follow.

This so-called "one" enchantment is actually formed by the convergence of tens of thousands of enchantments, each layer of enchantment has a different oscillation frequency, covering a large range from low to high, just blocking the Yuan Force oscillation area that Martial Venerable-level masters can reach, as well as the consciousness oscillation area.

In this way, it effectively put an end to the detection wave invasion of the Martial Venerable-level masters, so that they could not know what magic tricks were contained in the wooden box.

Now, Yitian understood the mystery, and with his own advantages, the idea entered the wooden box smoothly and detected the secret inside.

At this moment, Yitian had already walked around the eighteen bookshelves, and his eyes fell on the two wooden boxes, one of which contained the rumored Fire Dragon Technique, which was the earth-level upper-level magic technique, and the highest level and most precious magic method in the entire Tenglong Pavilion.

The other wooden box contained a book of different fire recipes, which turned out to be ground-level upper-level magic recipes.

As far as Yitian had mastered, among the forty-two wooden boxes, there were only these two local-level upper-level spells.

Among the remaining forty recipes, there are 12 prefecture-level middle-level recipes and 28 prefecture-level lower-level recipes.

"I'll pick these two wooden boxes. ”

Pointing to the wooden boxes located on different bookshelves and in different directions, Yitian broke the silence.

The gray shadow shook slightly, as if it was a little surprised, and looked up at Yitian.

At that moment, Yi Tian was surprised to find that this gray shadow turned out to be a person with long hair and a face, behind the messy hair, a pair of sharp eyes like knives were staring at Yi Tian, and the invisible thoughts were like sharp swords, wanting to penetrate Yi Tian's consciousness defense line and invade his mind.

With a strange smile, Yitian's eyes suddenly drifted, and then spun like a whirlpool, directly bounced away the idea of the gray shadow's invasion.

Gray Shadow's eyes moved slightly, his mind converged, he looked at the two wooden boxes on Yitian's fingers, and said in a deep voice: "Are you sure you won't change it?"

Yitian nodded and said, "If you don't change it, I'll choose it." ”

The gray shadow moved imperceptibly, and said indifferently: "In this way, you just take it." ”

Yitian questioned: "Don't you need to register?"

Gray Shadow said, "No need. ”

Yitian didn't ask much when he heard this, and directly took the two wooden boxes, and then left the Tenglong Pavilion.

Nangong Yun had just entered the first floor of the Tenglong Pavilion at this time, looking for a formula that suited him, and he didn't know the situation on the second floor at all.
