"This remnant is also a formation diagram. Seeing that Hong Xuan still looked puzzled, Ling Xian explained with a smile: "There are some high-level formations that are composed of several low-level formations. After speaking, he raised the remnant picture in his hand, "This is one of them." ”

Hongxuan also smiled after hearing this, but for some reason, she was still not very interested, and that smile looked as if she had been forced out.

Ling Xian was a little strange, but he was also thinking about other things, so he didn't pay too much attention to it.

"I want to ...... this map"

This map was indeed too important, so Ling Xian was also a little hesitant.

But before he finished speaking, Hong Xuan seemed to be awakened, and suddenly raised his head and said, "What?"

Ling Xian was also taken aback by her performance, only then did she notice that her face didn't seem to be normal, and asked, "Are you okay?"

Waving her hand, Hongxuan said, "It's okay, what did you just say?"

Ling Xian looked at Hongxuan's face now, but there was still a trace of sorrow between his eyebrows. The current red silk gave Ling Xian a feeling that was completely lacking in the hotness and cheerfulness when they first met, as if they had suddenly become sentimental.

Frowning, Ling Xian wanted to say something, but he had always been clumsy in his tongue, so he only squeaked on the side for a long time, but he didn't hold back a word.

Hong Xuan knew what he wanted, and also smiled, and said, "Don't worry, I'm fine, what did you want to say just now." ”

Seeing that she had finally changed back to her previous appearance, Ling Xian's heart was also slightly relieved, pondered for a moment, and said, "I want to borrow this remnant diagram and study the formation on it." ”

After speaking, he also looked at Hongxuan a little nervously, but he didn't expect Hongxuan to look like he didn't care, and waved his hand and said casually: "You can take it, anyway, it's useless for me for the time being." ”

Looking at Ling Xian's touched face, he also felt funny, and the sorrow in his heart was also dispelled a lot.

......

......

There was not much time left before departure, and both Hongxuan and Ling Xian still had a lot of things to do, so Ling Xian also quickly said goodbye to Hongxuan and found a room where no one was there to settle down temporarily.

Just now when he was in the house with Hongxuan, Ling Xian had only taken a general view, but now, he had enough time to study this formation diagram carefully.

The formation recorded in this formation is called Thunder Falling from the Sky, which is a second-level formation, according to what it contains, the Thunder Falling from the Sky can call the Nine Heavens Thunder, the evil in the world, the power is extremely extraordinary, and it is a powerful attack formation.

Ling Xian was also overjoyed, now he had too few means to attack, although the one-handed archery technique could be regarded as superb, but Ling Xian's current level was only in the late stage of guarding, although it was not slow to enter the realm, it was inevitably a little insufficient, and the arrows shot could only harass and harass the cultivators of the Ruo Yu period, but it was difficult to pose a substantial threat to them.

It was only with the cooperation of the eight Flame Palms and the Silver Bottle that Ling Xian could barely exert the strength of a second-level mercenary, but only with this, if he really had to face those powerful enemies in this mission, it was needless to say how much pressure he had.

And if Ling Xian could master this second-level formation and thunder descended from the sky, then his strength would have a big leap forward, and he would also have a little more confidence in this upcoming task.

However, this was a second-level formation after all, and Ling Xian was not sure in his heart. Although the second-level formation seems to be only one level higher than the first-level formation, in fact, the difficulty is not much higher.

The level of the formation is determined by the formation pattern it needs, the first-level formation only needs less than ten formations, and a second-level formation needs ten times as much, and the top one even needs a hundred formations, and each additional formation pattern is a great test for the opponent, and its difficulty can be imagined.

But fortunately, this Thunder Heavenly Descent was not the top in the second-level formation, and it was about thirty formations that were needed, otherwise, Ling Xian would not even have the courage to try.

Ling Xian's spiritual power re-entered the formation diagram again, feeling the charm of the formation left by the recorder.

The formation diagram is not just a simple line depiction, but more importantly, it records the formation master's understanding of the formation, as well as the model of the formation that is completely made up by spiritual power, which can allow the later generations to comprehend the true meaning of the formation more quickly, which is why Ling Xian must borrow this remnant diagram from Hongxuan.

Spiritual power entered this remnant diagram, Ling Xian felt as if he had come to a thunder world, countless thunderbolts fell from the sky and exploded around Ling Xian's body, although he knew that it was just an illusion, he couldn't help but feel a little numb on his scalp.

After a long time, Ling Xian was familiar with this environment, calmed down a little, and was finally able to concentrate on studying this formation.

Thunder was born in clouds and rain, but it was as fierce as a flame, indestructible, indestructible, and unbreakable, and has always been known for its attack power in various spiritual powers, and this thunder descended from the sky to gather spiritual power through formations to attract thunder.

Ling Xian felt a little bit in it, and felt that he had some experience, so he withdrew from the formation diagram and wanted to practice.

The spiritual power in the Sea of Divine Thoughts surged and came out of the body, forming a silver silk thread, which transformed into different runes under Ling Xian's control.

However, as soon as he began to set up the formation, Ling Xian sensed the difficulty of the second-level formation. Because the formation patterns were much more than the first-level formations, Ling Xian had to start the construction of several formation patterns at the same time, even if his control of spiritual power was beyond ordinary people, he was also quite stressed.

The array patterns shimmered with a glittering light, illuminating the entire room. The formation had already been arranged halfway, and Ling Xian's body was already covered with sweat, the difficulty of the second-level formation was even more difficult than Ling Xian had imagined, and the formation had been arranged until now, and the construction of each formation pattern would cost him a lot of mental power. Even in Ling Xian's sea of divine thoughts, there was a constant feeling of weakness, but his spiritual power was almost exhausted.

Syllable!

Ling Xian seemed to hear a clear sound coming from the void, but it was a silk thread made of spiritual power that did not withstand the pressure and actually broke, just for an instant, the originally shining runes dimmed and dissipated into nothingness.

The first attempt, failed.

Ling Xian sat on the ground and wiped the sweat from his face, but he didn't feel too much frustration. Originally, the difficulty of the second-level formation was a huge improvement compared to the first-level formation, and it was normal to fail, although he had always had no low requirements for himself, but he was not so harsh on himself, and he couldn't accept even a failure. So he didn't dwell too much on failure, but more than that, he was thinking about the problem of setting up the formation just now.

In fact, there are not too many problems, the most important thing is that he is unfamiliar with the formation and lacks understanding of the power of thunder, so the arrangement of each formation pattern requires a lot of his energy, and later the spiritual power is unsustainable, which ultimately leads to this failure.

However, the attempt just now also made his understanding of this formation more profound, and after thinking about it a little, Ling Xian also had a direction for improvement, and felt that his spiritual power had almost recovered, so he re-devoted himself to the practice of the formation.

When night fell, boundless darkness poured like a tide, eating away at the land, scrambling to squeeze into this small room, but was turned away by a thin figure, and around that thin figure was a light that was not bright but never extinguished.
