After hearing this, Qin Feng made an expression that was the same, and he felt that this was not the same as his previous guess, this formation was indeed a spirit gathering formation.

It's just that this formation is huge, almost encompassing the entire palace, and judging from the dense red formations on the platform, the structure of the formation is also very complicated.

"Eh, first put this Luo Xianyin away, and I'll quietly ask Nuwa if she can fix it. ”

Qin Feng thought about it, and then said to Luo Xianyin: "Pavilion Master, I'll take someone to study it first, and you can protect us from a distance to prevent outsiders from disturbing us." ”

Luo Xianyin nodded, and retreated a distance of dozens of zhang, looking at Qin Feng from a distance, with doubts in his heart, wondering if Qin Feng could repair the formation.

Qin Feng came to the heart of the formation at this time, and said to Nuwa and the Roaring Heavenly Dog, "You two, who can successfully repair the formation?"

The Roaring Sky Dog sneered and said embarrassedly: "Young Master, I will only destroy the formation." ”

Nuwa glanced at the formation, a little proud, and said, "Young master, I can fix it, this formation is very simple." ”

"That's great, you can do it. "Qin Feng Yile, Nuwa can really repair the formation.

Nuwa blinked, and said a little helplessly: "I need some materials, this formation is too badly damaged, and the level of the formation is not low, it should be a second-order formation." ”

"Formations are also divided into levels?" Qin Feng asked in surprise, feeling that he had to double the beginner beginner book on formations in his hand.

"Young master, everything in this world is divided into levels, and the formations are not excluded, they can be divided into ten levels in total, in the Heavenly Sword Dynasty where the young master is located, there are several first-order formations, first-order formations, which are the most ordinary formations, and when it comes to the second order, the formations will become complex and diverse. ”

"At the moment, except for the existence of a second-order formation in a middle-level dynasty, it is impossible for a low-level dynasty to exist in a second-order formation. ”

Nuwa said lightly.

"How do you know so well. Qin Feng was surprised, how could this Nuwa know so clearly about the system of this world.

"I am more special, in the ninth heaven of reincarnation avenue, when I signed the contract, I learned a lot of things in this world. Nuwa smiled mysteriously and didn't explain much.

Qin Feng remembered that Nuwa's attributes and cultivation had not been able to be checked until now, and had always been a secret, so he couldn't help but roll his eyes, secretly wondering if Nuwa was summoned by the system for the first time and made a bug.

"Don't talk nonsense, what are you waiting for, you hurry up and repair the formation. Qin Feng urged.

Nuwa shook her head, expressing her pity, and said, "This formation is seriously damaged, and I need a demon beast spirit crystal in the body of the demon king to repair it." ”

"It's embarrassing, I'll ask Luo Xianyin if she has it. Qin Feng greeted Luo Xianyin.

Luo Xianyin hurriedly ran over and asked anxiously, "How is it?

"What's so fast, do you have the Demon King's Demon Beast Spirit Crystal? Your formation is too badly damaged, and you need this thing to repair it as before. Qin Feng said seriously.

As soon as Luo Xianyin heard this, she couldn't help but roll her eyes, she looked like a girl, and then said speechlessly: "Where do I have this thing, a demon king is comparable to the strongest among the human race's supernatural martial artists, the demon king's demon beast spirit crystal is almost priceless, who will take it out and sell it?"

After hearing this, Qin Feng felt that it was also difficult to do now.

When Nuwa heard that there was no demon king's demon beast spirit crystal, she also shrugged her shoulders, indicating that she couldn't do anything.

According to her understanding, this formation is called the Nine Spirit Array, which belongs to a kind of Spirit Gathering Formation, with a complex structure and a wide range of coverage, if the formation is fully opened, it can include the palaces of the two Sword Shadow Pavilions, and can triple the space covered by the formation, and the intensity of the aura can be tripled.

The Nine Spirit Formation is a very precious second-order formation in many middle-level dynasties.

"By the way, isn't this a demon king? Nuwa remembered something, and then her smart beautiful eyes looked at the roaring dog.

When the Howling Dog heard this, he shuddered with fright.

"I'm not a demon king, I'm a divine beast, I don't have that kind of thing in my body at all, don't beat me up, young master. ”

The Roaring Sky Dog screamed sadly, hiding behind Qin Feng, staring at Nuwa very jealously, feeling that Nuwa was really a demon.

Seeing this, Qin Feng was a little amused, and said, "Don't worry, I won't want your demon beast spirit crystal, I'll think of other ways." ”

So he took out the formation introductory book, looked at it a few times, strengthened his second brain, and read the elementary introductory book, which was as simple as watching the three-grade martial arts, and browsed it once, and ate the content thoroughly, although he did not peek into the mystery, but he was also proficient.

"This primer book just talks about the content of the first-order formation. Qin Feng was depressed in his heart, but in front of Luo Xianyin, he pretended to be serious and confident, but he didn't dare to show his stuff.

Luo Xianyin is a smart person, just after glancing at the primary introductory formation book in Qin Feng's hand, he understood that Qin Feng was a formation rookie, and he was secretly disappointed in his heart, this Qin Feng is a typical temporary cram, but the annoying thing is that this guy is quite good at pretending, and he is still full of confidence.

After reading the formation book, Qin Feng pretended to be enlightened, and then came to the Dao platform and took a few closer looks, in fact, he didn't understand anything at all, so he frowned and thought.

"Pretend!" Luo Xianyin glanced at Qin Feng, Qin Feng didn't know at all that after he took out the beginner introduction book on formation, Luo Xianyin already knew what his formation level was.

Qin Feng was thinking about a way to repair the formation without the Demon King's Demon Beast Spirit Crystal.

After thinking about it, he finally thought of the use of demon points.

Qin Feng recalled that he had strengthened his martial arts several times, and this strengthening of martial arts was to improve martial arts.

A three-grade martial art, although it is already considered a top-notch existence in the Heavenly Sword Dynasty, and countless people regard it as a treasure, but it is also full of flaws, Qin Feng remembers that when he used the demon value to strengthen the Heavenly Sword Overlord Body Technique, he reached the level of the fifth grade.

The demon value is only perfected according to the cultivation path of the Heavenly Sword Overlord Body Technique, and it is constantly deduced and improved at a deeper level according to the cultivation ideas contained in the Heavenly Sword Overlord Body Technique.

In other words, it's not so much that the demon value is strengthening something, but stepping into the demon value is perfecting and repairing something.

Applying this idea to the current situation, maybe using the demon value can repair the dilapidated second-order formation in front of you as before.

"Hemp, I'm so smart, when to strengthen my brain again, I have to become smarter. ”

Qin Feng was secretly happy, his face did not change, he pretended to be a formation master, and walked onto the Dao platform engraved with countless formation patterns, located in the center of the formation.

He crouched down and propped his hands on the platform.

"Strengthen this formation for me. Qin Feng used his demonic power to give an order in his heart.

Suddenly, a strange black line appeared on the hands, and a light purple light emanated from the line, and finally merged into the platform.

Then Lolo's voice rang out.

"Ding, the host has successfully strengthened the second-order formation [Nine Spirit Array], and the demon value is 1500 points!"
