Elder Yi stayed on Yun Yu's body, but he was slightly surprised, such a big movement that it was difficult for him to control his body for a moment, and this Lingxia young man actually didn't react at all.

After a moment, his mood relaxed slightly, and the only explanation was that Yun Yu's level was still low, and it might not be enough to perceive such a strong aura.

"What's the matter, Elder, ...... you" Yun Yu also saw Elder Yi's reaction, and asked with a little inexplicability in his heart.

Elder Yi tried his best to calm himself down, barely squeezing out a smile and shaking his head.

"It's nothing, remember not to go too deep, first cultivate at the entrance of the cave. ”

"Thank you, Elder, for the point. ”

After speaking, Elder Yi got on the flying beast with a worried face, and when he slowly rose into the air, he thought: Today's feeling, that guy seems to be at the high-end level of the war spirit, the only possibility is that it is a lot closer to Thunder Island, so let's go back and report to the Xia Yuan quickly.

Watching Elder Yi ride the beast away, Yun Yu put away the confusion on his face and walked into the Spirit Cultivation Cave.

The moment he entered the cave, Yun Yu felt the impact of the strong aura in the cave, and even his body leaned backwards for it, so he hurriedly took a few steps back, took a deep breath, adjusted the sudden tension, and made some basic mental preparations again, and walked in again.

Sure enough, the strength of Lei Island is much stronger than that of Wind Island, with the strength of his own Lingxia five-star, it is not enough to enter it at all, and it is a little laborious to go one meter at the entrance of the cave.

I remember that in the Wind Island, although the ontological attributes are different, you can also cultivate for a moment at two or three meters, and the spirit cultivation can feel the impact, while in the Thunder Island, although it is the same attribute. One meter seems to have reached the limit, and the gap is obvious.

After suffering a strong loss in the wind island, Yunyu no longer challenged the limit, retreated another half a meter, and bent his knees to meditate.

In such a position, it can be said that at the boundary between the spiritual cultivation cave and the outside, you can still see things clearly through the light outside, of course, except for the depths of the cave, it is still invisible.

Before entering the state of spiritual cultivation, I felt a trace of movement in the spiritual power sensing area. And with that came the uplifting sound.

"Boy, well done, the speed of this star is worthy of the thunder attribute!" Mo Xian praised.

"Teacher, this is mainly with the help of Thunder Island's aura, and the disciple didn't expect it. It took two days to break through the five-star. Yun Yu said.

"Hehe, this state has to be maintained. Strive for seven days. Go deep into the hole. Mo Xian said with a smile.

Yun Yu was stunned for a moment, now he feels very laborious at a distance of one meter in the cave, I am afraid that it will be even more laborious to enter the state of spiritual cultivation, and it is difficult to go to the blue sky in seven days.

"Why is it seven days? The disciple saw that the depth of the cave was about ten meters away, and it was too difficult. ”

"Seven days. One more day, if it is exceeded, I am afraid that it will be forced into the cave," Mo Xian's voice was a little serious. "But you don't need to go to the end of more than ten meters, only six or seven meters away is enough." ”

"Teacher, why is this time so harsh......?

"It's better to fight back than to lose your life, as long as you live, the old man can let you recover, but if you die......"

Yun Yu couldn't help but be shocked when he heard Mo Xian's words, and instantly remembered Elder Yi's instructions, and asked, "Dead?" Is there any danger in this Thunder Island. ”

"That's right, there are war spirit beasts in this sea area, and they are definitely not at the level of war spirits, I think, Xia Gu'er also felt it, calculated, seven days should be just right to this island area. Mo Xian's tone was very affirmative, which showed that this was an ironclad fact.

Battle-level spirit beasts...... Hearing this name, Yun Yu was completely stunned, in the past, in the Mengbi Mountain, the strength of the five-colored anaconda was still in front of him, but it was only just promoted to the war spirit level, and now this spirit beast is definitely not at the war spirit level in Mo Xian's mouth, it seems that it is only high.

And in the face of the five-colored anaconda that day, if it weren't for Mo Xian's help, I am afraid that he would have been buried in his mouth, and now the teacher is not around, but he will not survive.

"Teacher, if that guy really appears, I'll hide in the hole?" Yun Yu asked stupidly, his tone very stiff.

"Nonsense, do you still want to fight, do you think you will have a chance of winning?" Mo Xian reprimanded.

Yun Yu pondered for a moment, and suddenly showed a weird smile, and said: "If the teacher is here, it won't be, kill it, if I am lucky to have a spirit beast soul, wouldn't my beast soul position be ......"

"Give up this idea, it is impossible for me to appear, I checked the situation of this thunder attribute spirit cultivation island for you before, I am afraid that Xia Gu'er has already sensed my aura, and if it appears again, my identity must be exposed." Mo Xian said, his tone was very resolute.

Listening to Mo Xian's words, Yun Yu's smile just now suddenly disappeared, and he thought in his heart, although Mo Xian's strength is elusive, it is also difficult to compete with the battle immortal level spirit beast, so simply tell the truth that you are afraid of that battle level spirit beast......

Yun Yu sighed in disappointment and said, "Hey, if you want to cultivate your soul more vigorously, I hope that seven days is enough to reach a depth of six or seven meters." ”

"Okay, I can't psychic with you for too long, that Xia Gu'er is careful at the moment that I may be heavier than that spirit beast, you cultivate your own spirit, and you will meet during the holidays." ”

"Teacher, where are you?"

......

Yun Yu had long been accustomed to Mo Xian disappearing when he said that he would disappear, and when he heard no reply, he smiled helplessly and entered the state of spiritual cultivation.

I thought that there would be some kind of spiritual cultivation resistance after entering the spiritual cultivation, but in the early stage after the spiritual energy in the meridians began to operate, Yun Yudao did not have any special feelings, but felt that under the catalysis of the spiritual energy in the cave, the speed of operation involuntarily accelerated, and there was no need for how to control the spiritual power, so it circulated very regularly.

But after a long time, it was like being on the Wind Island, when I felt that the great wind was coming from the cave, making it impossible for people to concentrate, and on Thunder Island, I actually felt that the lightning was shooting towards me, although the epidermis was not injured, but the meridians suddenly stinged, which was very unbearable.

Suddenly opened his eyes, only to find that he was already covered in sweat, and immediately rejoiced, if he quit the spiritual cultivation later, I am afraid that it will be difficult to feel his physical condition in the spiritual cultivation state, and he will be directly devoured.

But this strange state has never been possessed in Wind Island, but it has been produced in this Thunder Island with the same body aura, so strange, Yun Yu couldn't help but move a few steps to the entrance of the cave, thinking.

The characteristics of the thunder attribute aura are irritable and strong, Yun Yu couldn't help but think of the Zhan Sa aura, although it is stronger than the Zhan Sa aura, but the general meaning is the same, thinking of this, Yun Yu nodded slowly.

The immortal doctor's anger is extremely lethal and explosive, and if he is not careful, he will hurt others and himself, but the person who created the internal strength uses the softness of the medical sa aura to cooperate with the swiftness of the war sa aura, and achieves the purpose of attacking without harming himself.

Yun Yu smiled as if he had just woken up from a dream, and immediately walked back to a depth of one meter, meditated cross-legged, put his hands on his knees, and several green spiritual qi flowed from his fingertips on the surface of his body.

As soon as Yisa Aura came out of his body, he was driven away by the powerful thunder attribute aura in the cave, and soon floated outside the cave, but Yunyu directly ignored the situation and continued to force out Yisa Aura from behind.

As the saying goes, when the aura of the medicine is diffused, it is as soft as cotton wool, but it is like the cloud, which has just been blown away by the wind, and then closed and restored to its original state.

Yun Yu used his spiritual power to manipulate the aura of the external medicine to tightly attach to his body, forming a nearly transparent protective layer, although it seems to be thin, but after a long period of internal and external circulation of the body, it is tenacious.

With the medical aura to protect the body, Yun Yu felt that the impact of the aura in the cave was a little less, and the body was also a lot more comfortable when he cultivated the spirit in the warm recuperation, and at the same time, he cultivated the aura of the medical sa, which was also a kind of double cultivation.

Although because of the strong aura, I didn't dare to take out the blue water and green bamboo for double cultivation, for fear that the strength would be too strong and it would backfire, but the double cultivation of the two auras not only played a role in the level breakthrough, but also enhanced the strength of the medical aura, which can be regarded as killing two birds with one stone.

I don't know how long, Yun Yu gradually entered a state of concentration, his body was tightly wrapped in the aura of Yisa, and on the outside, there was a slight thunder attribute aura circulating, which looked extremely mysterious.

The meridians still often felt the lightning in the cave, but it was obvious that the pain was no longer unbearable, but just an ordinary touch, but stronger than the friction of the aura swimming in the meridians.

During the spiritual cultivation, the corners of his mouth were slowly raised, and Yun Yu thought to himself: If the spiritual cultivation is done in this way, I am afraid that when the seven-day period is over, it is not impossible to enter a depth of six or seven meters. (To be continued......)
