True Pole Cave, one of the three major cultivation sites on the periphery of the True Martial Palace, is divided into five layers, the first three layers are for disciples and disciples of the realm below the sixth-turn Void Immortal Realm, and the two layers are for the disciples of the elders of the seventh-turn Peak Void Immortal Realm.

After Liang Yu came to the door, he directly handed the identity token to the elders stationed here. After the garrison elder took Liang Yu's token, he returned it to him after a little verification. Then, Liang Yu walked down a staircase into the True Pole Cave.

After entering, Liang Yu found that this True Pole Cave was actually underground, and the depth of the underground was not shallow. After descending five or six miles down the passage, he reached the first level. However, Liang Yu didn't stay here for long, because this was not his destination, here he just briefly felt the concentration of spiritual power here, and then continued to walk again.

From the first floor to the second floor, the distance of the passage is about ten miles. When he reached the second layer, Liang Yu found that the concentration of spiritual power here was almost five times that of the first layer, and another obvious change was the temperature, which had obviously increased a lot, and there was already a feeling of heat rolling.

From the second layer to the third layer, the distance increased to nearly twenty miles, and the concentration of spiritual power was ten times that of the first layer, and nearly half of the immortal qi appeared in the spiritual power, and the temperature rose by another level.

After nearly thirty miles, Liang Yu finally reached the fourth layer, and after a brief estimate, he had reached a depth of sixty or seventy miles underground at this time. The concentration of spiritual power has reached fifteen times that of the first layer, and the content of immortal qi has reached the level of one percent, of course, this level is not comparable to that in the True Martial Pagoda at all.

As soon as he entered the fourth floor, Liang Yu felt a wave of heat rushing over his face, making him feel as if he had entered a steamer. However, soon Liang Yu found that his flesh cells actually had a little bit of strengthening under this high temperature. It seems that in this True Pole Cave, not only can the realm be improved, but also the physical body can be strengthened, and it is a good place to cultivate both inside and outside, which is also the reason why Liang Yu came here first.

Stepping into the entrance of the fourth floor, Liang Yu was able to truly see the situation inside the True Pole Cave. Here, it's actually a magma shijie, no wonder the temperature is so high.

On the fourth floor, the scope inside is very large, anyway, you can't see the edge at a glance, and Liang Yu didn't use his divine sense to investigate, because there are many other fellow sects here who are cultivating in various hidden corners, and it is also very rude to release his divine consciousness by himself.

The magma here is gathered in a magma lake of different sizes, churning and tumbling, like hot porridge in a boiling pot, and the color is also fiery red.

However, the strange thing is that the spiritual power here is not pure fire attribute, but very rare and non-attributed, so anyone can come in, but if it is a fire attribute person who comes in, it seems that the adaptability to this high temperature is stronger, and the time spent in it can be longer.

In fact, one of the differences in cultivating in the True Pole Cave is reflected in the time of each insistence, due to the particularity of this high-temperature environment, there is a trace of fire poison mixed in the attributeless spiritual power here, and this fire poison will accumulate in the body with the absorption of spiritual power by the monk, and when the amount accumulates to a certain extent, it will cause a certain amount of damage to the monk's divine consciousness body. Although this process is painful, it is also very capable of testing the cultivator's will, and when the cultivator recovers from the damaged state, he will find that the quality of his divine consciousness has also been improved.

So, every once in a while, the monks who practice here have to leave and take a special fire-dispelling pill to expel these toxins from their bodies. And the raw material of the fire dispelling pill comes from the blood of a biological rock fire beast in these magma.

Generally speaking, the maximum time for a seventh-turn or eighth-turn cultivator to cultivate at the fourth level is not more than three months, and this time cannot be used for all cultivation, so he must spend a certain amount of time hunting rock fire beasts. Every time you leave, it is usually not half a year for you to come here for a second cultivation.

Of course, the benefits always match the costs, and the speed of cultivation here is very fast, and you can also obtain multiple enhancements in spiritual power, divine consciousness, and physical body.

There were once people who insisted on entering here ten times in a row, each time for a month, and as a result, they improved the two small realms of the Void Immortal Realm, and it took less than five years before and after. Of course, the pain in this can be imagined, so many people wanted to learn from him, but they couldn't persevere.

These things were all obtained by Liang Yu from his girlfriend.

Besides, after entering the fourth layer, Liang Yu slowly walked inside along the edge of the magma lake, preparing to find a place with the right concentration of spiritual power and temperature.

And in the process, he also saw the appearance of the Rock Fire Beast. If you don't deliberately look for it, it's generally hard to find these small guys in the rolling magma, the same color as magma, and the skin is rough, and there are patches and bumps scattered on them.

After a cursory feeling, Liang Yu found that the Rock Fire Beasts he saw were all relatively low strength, only equivalent to the level of the Thunder Refining Realm.

And along the way, Liang Yu also found a lot of fellow disciples who were hidden in the main peaks of the True Martial Palace cultivating in a certain place, and also saw the scene of hunting rock fire beasts.

After some searching, Liang Yu finally arrived at the innermost place of the fourth layer, where there was a very large magma lake, where the temperature was obviously higher than other magma lakes, and here he also felt the breath of the Void Immortal Realm Rock Fire Beast.

In the midst of this huge magma lake, there is actually an island in the middle of the lake. With the naked eye, Liang Yu could see that it should be the hottest there, because the spiritual power there was so hot that it formed a shaky transparent film, which could only be formed at high temperatures.

"This is it!" Liang Yu secretly determined his destination in his heart.

Here, Liang Yu has not seen anyone flying, and he doesn't know if he can fly over. To be on the safe side, Liang Yu decided to give it a try, as he had a gut feeling that there was some danger in this huge magma lake!

Liang Yu summoned the fire phoenix out, and then let it fly towards the island in the middle of the lake first. As the fire phoenix flew over the magma lake, Liang Yu found that countless fiery red light points suddenly emerged from the magma lake and flew straight towards the fire phoenix.

"Fire poisonous insects!" Liang Yu couldn't help but exclaim.
