Lu Kun hit a few heels in mid-air, and fell into the pit with some disgrace, and finally struck with a blow to his arm, exhausting the mana in his body, and there was no way to fly in the air.

Lu Kun shook off the dust on his body, and jumped towards the place where he punched before, only to see that at the bottom of the hole, the ground about a zhang in size was pierced, revealing a silver prohibition, and there was a faint trace of black halo circulating inside.

Seeing such a change, Xiao Jin and Da Hei also rushed over, and they both looked curiously at the silver prohibition that appeared at the bottom.

Lu Kun injected his divine sense into his eyes, and the golden light in his eyes was full of gold, looking at this prohibition.

After entering the middle stage of the ancient treasure, Lu Kun's divine sense also surged a lot, and it completely reached the level of the late stage of the Jiedan, but there was still a certain distance from the peak of the late stage, his divine sense had improved, and his golden eye divine power had also made a lot of progress.

Lu Kun looked at the bottom of the pit and muttered to himself, "Could it be that this is the prohibition at the bottom of Demon Spirit Island?"

"Hey, this black light inside looks familiar. ”

Lu Kun's face changed slightly, and a spiritual light flashed in his mind.

"Demon Cave!"

The black mang looked like the color of demonic energy, which immediately reminded him of the demon cave.

After the battle of the Demon Cave that year, and the information obtained from the Li brothers, Lu Kun knew that the location of the Demon Cave was under the Demon Spirit Island.

Just now, he bombarded a depth of more than 100 zhang, just touching the prohibition at the bottom, and judging from the rise of the entrance to the bottom of the demon cave, it was almost this height.

"In this way, the prohibition between the Demon Spirit Island and the Demon Cave is connected, the spiritual energy and demon energy in the Demon Spirit Island are very abundant, and the demonic energy in the Demon Cave is rich, and there is even a real demon pool water. ”

"Is there any necessary connection between the two?"

Lu Kun looked at the prohibitions connected below, and felt that the strange design between the Demon Spirit Island and the Demon Cave must have a huge secret.

Judging from the location of the Demon Cave, both it and Demon Spirit Island are located in the Sea of Chaos, and there is pure energy inside.

But the aura of the Sea of Chaos was just the opposite, mixed with aura demonic qi and demonic energy, and these three energies were not calm at all, they often surged with each other, and no immortal cultivator could cultivate here.

The Sea of Chaos will even form a powerful chaotic storm because of this, even a high-level cultivator can't compete with it, and the Yuan Infant Fang Ancestor of the Yueyang Sect back then was also swept into the Demon Spirit Island by this terrible storm inexplicably.

The Dead Sea, which is adjacent to the Sea of Chaos, does not have the slightest aura or demonic energy, and it can be said that it is two extremes with the Sea of Chaos.

To say that the two seas have nothing to do with Demon Spirit Island and the Demon Cave, Lu Kun said that he didn't believe anything.

Judging from the situation of the ancestor of the Yueyang Sect, there is a good chance that the chaotic storm is related to the prohibition of the Demon Spirit Island, otherwise it would not have been possible to be swept into the Demon Spirit Island by this storm, and it was because of the chaotic storm that Lu Kun successfully found the Demon Spirit Island.

However, after Lu Kun and the others came to Demon Spirit Island, it seemed that the number of chaotic storms had greatly decreased.

Not to mention the Sea of Chaos, the location east of the Dead Sea is where the Qi country is located.

The entire Qi country is filled with aura and demonic energy, which is also mixed energy, but unlike the sea of chaos, the fluctuation of aura and demonic qi is very stable, as long as the immortal cultivator cultivates quietly, the mixed aura can also be absorbed into the body, and it does not have much impact on cultivation.

And because of the demonic qi and aura, it is more suitable for the cultivation of demonic Dao exercises, which leads to the prosperity of the demonic path of Qi.

Speaking of Qi State, Lu Kun remembered the One Yuan Secret Realm again.

The one-yuan secret realm is located in Zhongzhou of Qi Kingdom, and it is usually the same as the Dead Sea, without any energy, but every three hundred years, the year when the secret realm opens, a large number of spiritual qi and demonic qi will appear, forming extremely chaotic energy, and the scene is similar to the chaotic sea.

The changes in this Yuan Secret Realm, the scene of the Dead Sea and the Sea of Chaos, the relationship between the Demon Spirit Island and the Demon Cave, Lu Kun connected them at this moment, and immediately noticed that there seemed to be a line connecting them.

"It is rumored that the Yiyuan Secret Realm was built by the Yiyuan Sect, could it be that the ancient prohibitions of the Demon Spirit Island and the Demon Cave were also built by them?, but what is the purpose of the existence of the Demon Spirit Island?" At this moment, Lu Kun couldn't help but open his mind, and he always felt that he had discovered some secret.

Thinking of this, Lu Kun's pupils shrank suddenly: "By the way, the Demon Island in the overseas land was very similar to the Demon Spirit Island, and like the Yiyuan Secret Realm, it appeared once in three hundred years. ”

The situation on Demon Island looks somewhat similar to that of Demon Spirit Island and Yiyuan Secret Realm, and the prohibition outside Demon Spirit Island is also entered and exited through the Demon Order, and there is also a strong aura and a strong demonic aura in Demon Island.

Judging from the fact that Tian Renjie was finally killed by him and fell into the ban in the center of the Demon Island, as well as the situation of the Demon Clan's seizure of Tian Renjie, the place at the core of the Demon Island must have a strong demonic aura.

After taking a closer look, he found that Demon Island seemed to be a more mature Demon Spirit Island, the former enveloped the demonic energy, and the power of prohibition could make the island only appear once every three hundred years.

In comparison, the One Yuan Secret Realm is more extensive and mature, and it can be seen from the news obtained by Qi Guo that in the upper part of the One Yuan Secret Realm, there is only the existence of demonic energy, and there is no aura and demonic energy.

"Speculation, from the chronological point of view, Demon Spirit Island should be the oldest, followed by Demon Island, and finally, it is the one-yuan secret realm of Qi State, compared with the three, one is more complete and mature than the other. ”

Lu Kun glanced at the one-yuan jade pendant in the storage bag and muttered, "That demon soul must know something, it's been a year, and it's time to beat him later." ”

Shaking his head, Lu Kun walked to the side of the pit, two magic stones appeared in his hands, and began to run the Blood Demon Bone Alchemy Technique, absorbing rich demonic energy from the magic stones and transforming demonic spiritual power.

Only after his mana is exhausted can he cultivate blood magic power, after all, blood will enter the bones from time to time, and with his current mana level, there is a chance that the blood magic power at the foundation building stage level will be easily eliminated.

In the first ten years of cultivation, Lu Kun first replenished the blood magic power, wrapped it in the depths of the bones with essence blood, and then cultivated the mana of the Dan period, so that there would be no conflict.

Being in the Demon Spirit Island, Lu Kun was very assured of his safety, and he was running the exercises in place, according to his estimates, at least he had to cultivate a blood magic power to build a foundation and great perfection before he could urge the power of the arm.

Da Hei on the side looked at the magic stone in Lu Kun's hand very curiously, the breath inside reminded it of the great battle in the demon cave, and it still had lingering fears about the strength of the demon clan.

And Xiao Jin's eyes looked a little strange, it looked at Lu Kun's cultivation in a daze, and there was a faint golden light on his ears, it was operating its own unique supernatural powers, learning the exercises that Lu Kun was working at the moment.

The breakthrough of Lu Kun's bone treasure period is the refining of the magic weapon of the bone, and there is no unique operation of the exercise, and the little monkey can't learn anything, but at this moment, the method of cultivating the magic spirit power in the blood demon bone alchemy operated by Lu Kun is completely learned by the little monkey with its special spiritual ear and divine powers.
