Gu Yun slowly walked in the furious lightning, and sometimes even stopped to think. And many more people trapped here are running like crazy.

But this crazy running only slightly alleviated the boredom in the heart, but it made the mood more manic, the running did not reduce the bombardment of the thunder and lightning on them, nor did it make them see the end of the road, but it affected their own hearts, but they also missed a lot of things.

So, sometimes what you see, the best and only thing that can be done right now is not necessarily the right thing.

Gu Yun was in this seemingly careless slow walk, which made his boring and lonely heart seem a little ethereal, and it was precisely by adjusting his heart to this state that he felt a little different in this hole.

He found that the cave was not always in such a state of extreme light, but alternating between light and dark, and because the speed of this alternation was so fast that it was not even a ten-thousandth of a second, and man himself was more sensitive to this light than darkness, he always felt that this cave was an environment of extremely bright and full of light.

So what does this alternation of light and dark mean?

Gu Yun judged and analyzed this alternating interval, although the alternating time was extremely short, but this interval was still distinguished, and Gu Yun's analysis of this interval found that this alternation of light and dark was simulating a kind of fluctuation, or that it was transmitting a message to people.

After a long time of judgment and analysis, Gu Yun finally figured out that this information turned out to be a secret method of cultivation, but it was a kind of ground-level secret method when it came to grade.

"Thunder Pill Sutra!"

This can be said to be a secret method of refining the body, but it is different from various exercises for cultivating the body, this secret method is only through refining the flesh of the human body with the attribute of thunder and lightning, and its cultivation method is to make people like alchemy, with the human body as an elixir, through the quenching of thunder and lightning, and after continuous strengthening, the body has the attribute of thunder and lightning, so as to prepare for the next attack secret method.

After Gu Yun learned this, he thought that this might be the key to getting out of this cave.

If you want to go out, you can only practice this "Thunder Pill Sutra" first.

I don't know what happened to Zi Bing.

Gu Yun thought so in his heart, but then put this worry aside, thinking that with Zi Bing's cultivation and qualifications, he realized that there should be no problem, even if he didn't realize it, he thought about it in vain, and if he wanted to save her, he could only go out first.

As soon as he thought of this, Gu Yun couldn't wait to cultivate the "Thunder Pill Sutra".

Running the "Thunder Pill Sutra", he felt that the thunder and lightning around him were a little more violent, and Gu Yun, who had already adapted to this kind of thunder and lightning bombardment, also felt a little unbearable, but at this time, only persistence, and only persistence could have hope of getting out of here.

Slowly introduced the more and more violent thunder and lightning vitality into the body, and suddenly the flesh and blood in the body and the five internal organs and six organs were like a knife cut, but fortunately, there was a true qi that refined Zi Bing when refining the thunder dragon qi before.

At this time, there was a bit of purple ice true qi in his own true qi, and Gu Yun also urged his own vitality to blend with the thunder and lightning vitality that was introduced into the body from outside the body, but found that the vitality containing the attributes of purple ice true qi could repair the part that was damaged by the thunder and lightning vitality, and greatly relieved the pain like torment.

Gu Yun said in his heart, if Zi Bing also obtained this kind of mental method, then it should be much easier to cultivate than him.

This was indeed the case.

After Gu Yun guided the thunder and lightning energy to run in his body for a week, he found that the faint lightning light in the flesh and blood in his body had flickered when he was refining the thunder dragon qi, but at this time, it was becoming more and more obvious.

Moreover, there are also thunderbolts running in the body, and there are thunderbolts gathering like thunderclouds and colliding with each other, making the meridians also like a world of thunder and lightning, flashing with lightning, bright and extinguished, and the vitality of different attributes is constantly blending and decomposing

And as Gu Yun progressed in cultivating this "Thunder Pill Sutra", the thunder and lightning in this cave gradually increased his strength, perhaps only in this way could he better temper the cultivator's physical and mental flesh and blood, so that the effect of the "Thunder Pill Sutra" cultivation would be better.

"Buzz!"

Gu Yun's body was shocked, but he found that the meridians that were originally full of golden light suddenly became no longer able to see a trace of light, and fell into darkness in the meridians.

"Bang!

In the midst of the violent thunder and lightning in the cave, there were countless golden red points of light.

"Thunder Dragon Qi!"

Gu Yun exclaimed, this is the thunder dragon qi, look at the amount of nearly ten thousand daos, this nearly ten thousand thunder electricity came to Gu Yun's approach, but it was condensed into a smaller thunder dragon qi.

This nearly 10,000 thunder dragon qi condensed into one, what kind of energy is that, if it bursts out at once, I am afraid that this secret realm will also be erased.

So looking at this thunder dragon qi now, the thunder dragon qi was originally extremely bright, and nearly 10,000 daos converged, but it made this thunder dragon qi look a little illusory, and even felt a little dim, and this is also a manifestation of the extreme brightness.

And because this thunder dragon qi contained a huge amount of energy, his fluctuations also caused a small black hole to form around it, as if a piece of space was missing there.

And this thunder dragon qi rushed into Gu Yun's body at this time, rushing into the meridian that suddenly turned into extreme darkness, just like a golden light pierced the boundless darkness, the darkness in the meridian was rapidly dissolving, and in the blink of an eye, it became the same transparent and bright scene as before, flashing with colorful light.

And that thunder dragon qi didn't stay, it didn't break out, of course it couldn't break out, if it broke out, then Gu Yun didn't even have ash left, what kind of energy was that.

The thunder dragon qi rushed along Gu Yun's meridians to the nine cyclones, but this time it was not swallowed by the black hole, but suspended between the nine cyclones, and stretched out nine filaments to connect to the nine cyclones.

At this time, through the nine cyclones, he could clearly sense the powerful energy fluctuations contained in the thunder dragon qi, and obviously he could use these nine cyclones to mobilize the energy of this thunder dragon qi within the range he could bear, which was equivalent to Gu Yun hiding an energy bank in his body that could be accessed at any time, and it was safe and fast.

If you get that attack secret method later, it will be another powerful means, which is a lucky thing for Gu Yun, who is still weak.

When this thunder dragon qi stabilized between the nine cyclones, it emitted a golden light, dissolving the thunder and lightning attribute contained in it and the not weak life qi into Gu Yun's vitality and body flesh and blood

"Wow!"

Gu Yun's body suddenly erupted with blazing golden light, and then as if his body turned into the thunder and lightning light in this cave, it dissolved into this violent and bright golden light and disappeared

Gu Yun was now standing on a meadow, which was no different from the ordinary grass outside, with a small green grass, with many unknown wildflowers and some low shrubs in the middle, but no tall trees, with a wide field of vision, everything was as verdant and vibrant as if it had just been watered by the rain.

Gu Yun looked up, but there was a high mountain in front of him, but there was boundless darkness behind him, it seemed that this time there was a bit of a purpose, it should be to go to the top of the mountain.

The top of the mountain was submerged in the thick clouds, making this space a little dark, no longer the extremely bright environment that had been in place for a long time, but making Gu Yun feel very comfortable.

After all, no matter who is under the dazzling light for a long time, they will feel a little crazy, that is, these strong-willed cultivators can persevere, if ordinary people are in this environment, they must have already committed suicide in despair.

It's not pleasant to be in the dark for a long time, but if there is no darkness and only light, can you bear it?

Gu Yun flew towards the top of the mountain, but now there is no need to be slow, if you have a goal, you will naturally be fast.

As Gu Yun flew towards him, the darkness behind him also followed, and it was obviously impossible to retreat, only forward.

"Boom--"

The sky exploded, and the thick clouds on the top of the mountain cracked a long crack, and the electric light flickered in the crack, illuminating the originally dark space again, but this brightness was far less than the extremely bright environment before, so within the tolerance range of normal people, it was not enough to affect people's minds.

Of course, it won't ring for no reason, just to send you some light.

Immediately afterwards, Gu Yun saw countless thunder and lightning creatures rushing out of the huge cracks, saying that the creatures were a little wrong, but in fact they only had their forms and no gods, but they didn't know what word to use, so they were temporarily referred to as creatures.

Those thunder and lightning creatures had already besieged Gu Yun in the middle in the blink of an eye, and besieged them, Gu Yun judged from the fluctuations emitted by these thunder and lightning creatures that the strength of these thunder and lightning creatures was not particularly high, and it was equivalent to the level of the eighth stage of the normal sea storage realm, which was still within the range that Gu Yun could bear.

Gu Yun was temporarily promoted to the Sea Storage Realm when he entered this secret realm, and he was the kind of perverted character who could leapfrog the challenge, and the requirements for strength in the ancient exercises were already higher than the current ones, and the current cultivation was opportunistic and much more conducive to seedlings, so although his cultivation went up, his strength was not high.

Therefore, although the strength of these thunder and lightning creatures has the level of the eighth stage of the normal sea storage realm, it is not difficult for Gu Yun, the problem is that the amount of this thunder and lightning creature is too much, if it keeps coming, then being tired can also exhaust him to death.

Gu Yun pulled out the Ice Cloud Sword, and a colorful sword light swept out

"Brush!"

"Brush--"

The colorful sword light passed through the middle of these thunder and lightning creatures, and made a crackling sound caused by the collision and burning of true qi and thunder and lightning, and after penetrating through many thunder and lightning creatures, the colorful sword light energy was exhausted and disappeared.

And these creatures only shook their bodies for a moment, but they didn't take any damage, and then rushed towards Gu Yun again.

Gu Yunyi frowned, and while shaking his body that was a little numb from being attacked by the thunder and lightning creatures, he thought in his heart, why is this?
