"This is a formation?" said Void Feather with some confusion.

"I understand, the Netherworld Wind may have a lot to do with this natural array, this natural array is a wind formation, and it has the effect of amplification, it is likely that the big array will increase the Netherworld Wind infinitely. Lin Ruo thought for a moment and said.

"It's no wonder, because the Ghost Commander doesn't understand the formation, so he can't find out, brother, can you?" asked Xufei Yu.

"I don't know about this, it's a naturally formed formation, and it's very different from artificially arranged, so I don't know much about it, but I can go in and find out. Lin Ruo lit a tobacco stick and said.

"The power of the formation is very great, brother, you should study it before entering!" said Xu Feiyu with some concern.

"Sister, this is a compound formation, dozens, hundreds of caves are a large formation, and then a composite formation composed of such a large array, now this area is so large, I can't understand it outside the research. Lin Ruo said with a wry smile.

After listening to Lin Ruo's words, Xu Feiyu stopped talking, he knew that he was an expert against Fa Lin Ruo, and he just knew that he didn't know anything.

Lin Ruo threw away the tobacco stick, his body rose in the air, and flew straight towards the cave, with the Void Flying Feather following closely behind him.

After arriving at the first cave, Lin Ruo's body entered in a flash, and slowly probed inside, wanting to see what was going on in the cave.

Xufei Feather followed Lin Ruo's side with the Fire Feather Sword, guarding Lin Ruo.

Now that the line of sight is blocked, the divine power probe is also limited, in order to prevent emergencies, the Void Flying Feather can only do this.

Lin Ruo slowly walked forward with the talisman enchantment, although he knew that an ordinary cave might not be in any situation, but he was still very cautious.

The cave was very deep, and there was a whistling netherworld wind inside, and after entering six or seven miles, the cave branched off again, Lin Ruo thought about it, and moved towards the thicker passage.

Xu Feiyu followed closely behind Lin Ruo, not afraid of falling behind, but worried that something unexpected would happen and Lin Ruo would be injured.

As he advanced, after advancing for a while, Lin Ruo entered another cave.

"My conjecture is right, caves are connected to caves, and only in this way can it be justified, because of the connection, the nether wind can be sent out, and the cycle continues. Lin Ruo resisted the whistling Netherworld Wind and turned his head to the Void Flying Feather and said.

"Is there a way?" Whether or not it can solve the problem is what Xufeiyu is more concerned about.

"This cave is open in all directions, and it's not the way we can do it. Lin Ruo shook his head.

"What then?" Void Feather was a little unconfident, because Youquan had never solved it after coming here.

"Let's go back to the Xuan Spirit Realm first, and I'll think about it. Lin Ruo felt that it was not a way to explore like this now.

Returning to the Xuanling Realm, Lin Ruo took out a wooden stick and carved it on the ground, recalling the rough sketch of the cave he saw outside the mountain peak.

After half an hour, Lin Ruo drew a secret numb formation talisman, "Sister, come and see, is this one I drew the same as the general distribution of the caves outside?"

"It's the same, but if there's any deviation, my sister can't see it. Xufei Yu shook his head and said.

"I don't understand this formation, and there are deviations from the various formations of the wind system, like the Nine Palaces Frightening Wind Array, and like the Anti-Star Ganggang Wind Array. Lin Ruo lit a small stick and studied it slowly.

"This sister can't help you, my sister doesn't know how to form a match. Xu Feiyu said helplessly.

Lin Ruo was studying the formation and deducing at the same time.

Studying the formation was a mental and energy-consuming job, and after two and a half days, Lin Ruo let out a breath and stood up.

"Let's have a cup of tea first!" When Lin Ruo was studying the formation, Xufei Yu's tea was brewed one pot after another, just because he was worried that Lin Ruo would not be able to drink water if he was tired, so he didn't ask about the results of the research, because whether Lin Ruo was tired or not was more important in Xufeiyu's heart than the results of studying the formation.

"Thank you, sister. Lin Ruo took the teacup, took a sip and sat down.

"Don't be like this in the future, if you have a study, you can take a break and study again. Xu Feiyu complained to Lin Ruo, mainly out of concern.

"The effort will pay off, and I have deduced the approximate location of the formation eye. Lin Ruo put down the teacup and lit a tobacco stick and said.

"There are results?" Void Feiyu couldn't imagine that Lin Ruo had really researched his eyebrows.

"Yes, I don't know what the name of this formation is, it is a combination of the One Yuan Nine Palaces Frightening Wind Array and the Anti-Star Gangfeng Array, it has the characteristics of two formations, and the two formations are not in conflict but complement each other and are set together. Lin Ruo said the result of his inference.

"The formations that I haven't seen can be calculated, and my sister can admire you or not. Xu Feiyu's heart was full of surprise, he couldn't imagine that Lin Ruo would actually understand the formation he had never seen before.

"Whether it can be broken now depends on whether it can find the formation eye, but it is impossible to trap me. Lin Ruo said confidently.

"Brother, won't the undead be trapped by the formation here?" Void Feiyu asked a question that he was a little puzzled about.

"Not sure, in addition to the invasion of the strong Netherworld Wind here, the other is the labyrinth-like formation, the Netherworld Wind has no effect on the undead, as for whether the labyrinth-like cave can be trapped, it's hard to say, even if it can be trapped, there are not many, there are many undead in the Cave of Death, but it is not the undead produced here, this is just suitable for the undead to survive, and the undead are all foreign. Lin Ruo said slowly.

With Lin Ruo's explanation, Xufei Yu understood.

The undead are produced by the bones of dead people and animals absorbing netherworld energy, and the corpses near the cave of death are limited, which means that not many undead can be produced.

Most of the undead are foreign, and the undead can go to the vicinity of the cave of death to be high-level. The high-level undead have wisdom and will not go too deep, and of course they will be trapped if they go deeper.

"Brother, do you mean that there will also be trapped undead inside?"

"Well, if a human enters it, it will die if it is trapped, and whether it will become an undead after death is not to be said for the time being, but the undead will not be trapped to death, and being trapped reduces the chance of death, so the cultivation will be higher. "Some issues, Lin Ruo has also thought about them before and after.

"What do you mean, sister understands, let's be careful. Xufei Yu understood what Lin Ruo meant.

Lin Ruo didn't rush out, he took out the blood pill and cultivated under the thousand-year-old silver flower iron tree, he wanted to restore himself to his peak state, and then face the next challenge.

If Void Feiyu was not there, Lin Ruo would go to Haiyin Ji to draw energy, and then refine the energy while cultivating divine power. But let the woman she likes wait here, and go to another woman's business, Lin Ruo can't do it.

Two hours later, Lin Ruo became radiant, "Sister, we can go." ”

Holding up the talisman enchantment and wrapping the Void Flying Feather out of the Xuanling Realm, Lin Ruo followed the route he had deduced.

Without the protection of the talisman enchantment, it may be difficult for Lin Ruo to move forward, but he can still persevere, but the Void Flying Feather is not good, his body is not as strong as Lin Ruo, and it is easy to be entered by the Yin Wind, and it will be troublesome if the Yin Wind enters the body.

Lin Ruo moved forward with the Void Flying Feather, and various forks in the road kept appearing as he advanced, and Lin Ruo did not hesitate in front of the intricate cave entrance, and moved forward according to his own inference.

"Be careful!" Suddenly, an undead appeared, and a silver undead with a glittering silver body slashed towards Lin Ruo with a combat knife.

Lin Ruo ignored the undead's attack, and the Zhentian halberd appeared in his right hand and stabbed towards the undead's neck. At the same time, his left hand was raised, and the purple-gold light in his hand flashed, and he grabbed at the undead's sword.

The space here is relatively narrow, and Lin Ruo doesn't want the battle to affect the Void Flying Feather, so he directly attacks against the undead with attacks.

"Brother, retreat, this is the undead at the peak of the emperor level!" Void Feiyu was shocked when he saw Lin Ruo carrying the attack of the undead.

When he finished shouting, the undead's war knife had already arrived in front of Lin Ruo's body, after all, it was the undead who attacked first, and the war knife came into contact with Lin Ruo first.

At this time, Lin Ruo's left hand reached out and grabbed the undead war knife, stopping it from slashing him.

When he grabbed the undead war knife in his hand, Lin Ruo's Zhentian halberd also attacked the neck of the undead, and with the flashing of purple-gold light, the neck of the undead was cut off by Lin Ruoyi.

With a slash, he cut off the neck of the undead, and Lin Ruo's right foot burst up and kicked the uncontrolled body of the undead away.

When Lin Ruo kicked the undead body away, the undead's head flew backwards.

Although the connection between the body and the head was destroyed by Lin Ruo, the soul bead of the undead was still safe and sound, as long as it ran away, it could still find a body to slowly strengthen and restore cultivation.

Lin Ruo was willing to let him run like this, and with a flick of his left hand, the spirit war knife in his hand chased towards the head of the undead. With all that done, another shot of death came out of his empty left hand.

At this time, the Void Feather also moved, and a flame slashed out, blocking the path of the undead's head retreating.

Just when the undead's head was concussed by the energy of the Void Feather, the battle knife thrown out by Lin Ruo arrived.

Sensing the danger, the undead head dodged to the side, but due to the influence of the strong wind of the war knife, the speed was not very fast, and at this time, Lin Ruo's death spear arrived, shooting through its eye socket and piercing the back of its head.

Lin Ruo unexpectedly used the Sky Splitting Claw, so that the undead at the peak of the emperor level were killed without much strength to fight back.

"Brother, are your hands okay?"
