Chen Nan believed that after these few incidents, whether it was Langguang Dongtian or Yujianmen, they would not dare to come to make trouble easily, and he could be regarded as killing chickens to show monkeys.

Chen Nan is still very satisfied with the improvement of his strength, what he is worried about now is not the Yujian Gate and Langguang Cave Heaven, but the other sects will find out that he is in the Fengyue Sect, especially the Nangong Mountain Villa and the Piercing Heaven Palace, although the strength of the two sects has been greatly damaged because of the trip to the Two Realms Mountain, but it is far from being able to deal with the current Fengyue Sect, he is thinking that he has time to study the lower formation path more, if he can arrange a fifth-level formation, even if it is a beginner, he can also protect the Fengyue Sect without worry.

But he also knew that without physical objects, without the guidance of famous teachers, it was too difficult to study a fifth-level formation by relying only on his own fantasies.

Back in Fengyue Sect, Chen Nan brought Hui Jue and Grace to live in the Snow Pavilion Plum Garden. But he didn't stay any longer, explained to Zi Ling, and immediately went out of the Fengyue Sect to the Falling Ghost Ruins, and began to search for the Flame Spirit Fire according to the map.

The place where the ghost ruins are located, it is said that there was once a thriving family, but this family was suddenly wiped out for some reason, resulting in countless unjust souls here, and over time the buildings were dilapidated, forming the current ghost ruins, the meaning of the ghost ruins is the place where the ghosts gather, and the ghosts will stop here when they come, and take this place as their home, because this place is extremely sinister and often haunted, so it is extremely remote, and few people will easily set foot here.

When Chen Nan came to the Falling Ghost Ruins, he felt a gust of yin wind, and where he entered his eyes, there was a hazy mist constantly drifting by, and under his divine sense, he could easily see how many shadows were gathering towards this side, even if he was physically strong, he also felt a burst of coldness.

These ghostly things have not become a climate, they are just some unconscious ghosts, as a Jindan monk, Chen Nan is not afraid of them, even if he does not move, these ghostly things do not dare to get close, he is trying to sacrifice the fire of the earth to disperse them, and suddenly thought of duck eggs, here is a taboo for others, but it is a paradise for it.

With this thought, Chen Nan immediately released the duck egg, and as soon as the duck egg appeared, he screamed happily, as if he felt its breath, and those ghostly things scattered in a hurry.

The duck egg pounced and opened its mouth to suck it, and a shadow was sucked into the mouth, and in a blink of an eye, the surrounding area of Chennan became a lot brighter, and the cold breath gradually disappeared.

Duck eggs are rarely so happy, Chen Nan didn't put her away, let her catch the prey here, feast on it, she entered the depths of the ghost ruins and escaped into the ground, and it was not too late to take the duck eggs when she came out.

The map indicates that the ghost ruins are underground, but the specific path is not marked, not far underground, Chen Nan released his divine sense, and the remains of some buildings can be seen from time to time, which shows that this was indeed the place where a big family lived, although countless years have passed, its traces can still be seen.

It's just that Chen Nan's divine sense swept out, but he didn't find the hall that Gu Liang said.

"Could it be that the map is fake? That guy is lying to me for his life?" Chen Nan secretly thought, thinking about it, it was unlikely, because that ancient map of animal skins looked like a vintage, and it definitely looked like a forgery, not to mention that Gu Liang, a dragon cultivator, did not necessarily have the courage to dare to deceive himself.

Chen Nan released his Divine Sense and began to search carefully, and finally his Divine Sense swept to a hidden formation.

Seeing this hidden formation, Chen Nan finally knew why he couldn't find it just now, although this hidden formation is only second-level, it doesn't look like it's artificially arranged, but it seems to be naturally generated, if it weren't for the map, it's really hard for ordinary people to notice that there is a hidden formation here.

Chen Nan could see that this was originally a very clever magic array, at least he couldn't see the level now, because it had been too long and the spiritual power was missing, this hidden formation could not be fully operational, it was equivalent to the level of the second-level magic array, if it wasn't for that, even if there was a map, it would be difficult for him to find it at all, let alone Gu Liang of the Dragon Transformation Realm.

The second-level magic circle was still difficult for him, and Chen Nan easily entered the formation and came to a hall.

The hall is full of ancient meaning, although it is old, but at first glance it is artificially built, maybe it is left by the family that was destroyed, but this hall is reinforced by the formation, otherwise it would have become a ruin.

Since the hall is not natural, the hidden formation outside ...... Thinking of this, Chen Nan couldn't help but gasp, since the hall is not natural, the hidden formation is obviously not natural, the person who arranges the formation can arrange such a perfect magic array, that person's formation level is really terrifying.

Chennan walked towards the depths of the hall, and soon Chennan's eyes lit up, because he saw the flame, there was a groove in the wall, and there was a pale blue flame jumping.

Everything was as Gu Ming said, that flame was imprisoned by the formation, and it seemed to have been growing there, and outside the imprisoned formation was a fifth-level killing formation.

This killing array also seems to be naturally formed, but because of the lack of aura, it is now only equivalent to the level of a fifth-level killing array.

Chen Nan frowned, the confinement formation is extremely perfect, it seems to be natural, but this hall belongs to the ruins, and the appearance of natural formations in the ruins hall makes him always feel weird, if the formation is artificially arranged, everything makes sense, but if someone can arrange such a perfect formation, it is indeed too terrifying.

Chen Nan shook his head, "Regardless of him, it doesn't matter who arranges him, he will get the Flame Essence Fire first." ”

He can't break the fifth-level formation now, but he can already skillfully arrange the fourth-level formation, and he can completely break this killing formation through deduction, but it just takes time.

This flame still looks very weak, it stands to reason that it is best to let it grow up and then accept it, but the formation of a flame will take hundreds of thousands of years, where does he have time to wait, if he doesn't use it after acceptance, it is also good to give it to his own woman.

Chen Nan didn't waste any more time, not to mention comprehending the fifth-level magic circle, which would also be of great benefit to his formation level. He sat down cross-legged and began to deduce the large array.

Time passed little by little, and gradually, Chen Nan was completely immersed in the comprehension of the formation, constantly making various gestures, refining the formation flag, throwing the formation flag, and then being destroyed by the formation, and so on.

"Haha, there's really a flame spirit, I deserve to pick it up. As soon as Chen Nan caught the trajectory of the formation, he was awakened by a burst of laughter, he suddenly opened his eyes, and saw a person coming in at the entrance, this person was dressed as a scholar, his skin was pale, his fingers were skinny, and his nails were inches long.
