After the law enforcement disciples left, Lin Yu walked into the Golden Crow Grottoes, and suddenly a scorching breath swept in, like a volcano, burning mountains and boiling the sea.

"The temperature is really high!"

Lin Yu's eyes flashed, in such a place of punishment, ordinary people really couldn't stand it when they came in, and he finally knew why the law enforcement disciples stayed away from here.

Fortunately, Lin Yu's aura was majestic, and he had condensed the subtle seeds, so as long as he didn't go deep into the Golden Crow Cave, it wouldn't have any effect.

"What's going on?"

At this moment, Lin Yu sighed lightly, and a trace of doubt appeared in his eyes, and he found that as soon as he entered the Golden Crow Cave, the human emperor sword in his body trembled inexplicably.

And the direction of the tremor is the depths of the Golden Crow Grotto, as if something inside is attracting it.

Lin Yu frowned, his eyes looked into the depths of the Golden Crow Grottoes, his eyes kept flickering, and after a while, he shook his head and gave up the idea of going.

The Golden Crow Cave is divided into the edge and the depth, the edge is 100 meters in circumference, and after 100 meters, it is the depth.

And the scorching temperature in the depths has been raised by another level, and I am afraid that the inner disciples will not be able to stand it when they come, and they will not dare to set foot easily.

"Forget it, let's improve our cultivation first!"

Lin Yu suppressed the restless human emperor knife in his body, found a corner on the edge and sat up cross-legged.

However, soon, Lin Yu discovered a problem, that is, the aura here was too thin, and he couldn't cultivate at all.

"No wonder few people set foot here, it turns out that the aura here is so thin. ”

Lin Yu pursed his lips, what he originally planned to release his martial soul to cultivate now seemed to be unworkable.

The surrounding heat wave rolled in, making Lin Yu's skin ache for a while, and without thinking much about it, Lin Yu hurriedly transported the aura in his body and began to resist, and the dry feeling quickly disappeared.

Taking out a large number of six-pattern Gathering Spirit Pills from the storage bag, the first reward obtained from the outer gate Dabi finally came in handy at this moment.

After taking out the Six-Pattern Gathering Spirit Pill, Lin Yu began to cultivate, and took the Gathering Spirit Pill one by one.

"As long as there is a Gathering Spirit Pill, it is not impossible to cultivate here!"

Lin Yu's eyes were bright, and he found that cultivating here was also beneficial.

For example, the aura has been refined, and the skin membrane of the whole body has become thicker and thicker in the process of resisting high temperatures.

Screen away all kinds of messy thoughts, and just like that, Lin Yu fell into cultivation.

The sun rose and the moon set, and in the blink of an eye, Lin Yu stayed in the Golden Crow Cave for more than twenty days, and the period expired with one day left.

During this period, Lin Yu continued to swallow the Six-Pattern Gathering Spirit Pill, and his cultivation was also rising.

And what surprised Lin Yu a little was that the aura in his body was not only more majestic, but also very pure, as if it had been tempered for thousands of years, and it was spotless.

Not only that, Lin Yu's skin membrane became hard and thick under the torment of high temperatures, and in general, in the past twenty days, Lin Yu's strength has been well improved.

However, it was a pity that Lin Yu did not break through to the martial artist, and was stuck at the level of a half-step martial artist, and the thousand six-pattern spirit pills were also exhausted.

And Lin Yu also knew that even if he was given more Gathering Spirit Pill, even the Nine-Pattern Gathering Spirit Pill, he would not be able to break through, as if there was an invisible barrier blocking it, which was insurmountable.

"The human emperor knife is getting more and more restless!"

Waking up from the meditation, the doubts in Lin Yu's eyes were even stronger, in the past twenty days, every day that passed, the feeling of restlessness in the human emperor sword in his body became more and more intense.

"What is there in the Golden Crow Cave that attracts the Human Emperor Sword?"

Standing a hundred meters away from the edge, looking at the depths of the Golden Crow Grottoes, Lin Yu fell into deep thought.

Although his strength has increased a lot in the past twenty days, he still doesn't dare to cross the thunder pool, and from that distorted space, he can know that the temperature in the depths is high and terrifying.

And the aura inside is thin, and it can't replenish the aura, and relying on one's own aura alone is a drop in the bucket.

"By the way, why am I so stupid, the restlessness of the human emperor knife naturally has its reason, and there may be a way to release it!"

Lin Yu's eyes suddenly lit up, he felt that the aura here was thin before, and he had forgotten about this stubble.

As soon as he thought of it, Lin Yu released the human emperor knife in his body.

Nine yellow rays of light rose up behind Lin Yu, and the ancient war knife filled with mysterious runes slowly appeared.

After the Human Emperor Sword appeared, it happily danced around Lin Yu, like a naughty child who had been locked up in a small black room for a long time, completely liberating his nature.

After venting for a while, the Human Emperor Sword stood beside Lin Yu, and then a bright light diffused out, enveloping Lin Yu.

Under the light, Lin Yu felt that his whole body was extremely cool, and the scorching temperature outside had been completely isolated.

"There's a way!"

Seeing this, Lin Yu's face was a little happy.

And after releasing the light, the human emperor knife pointed directly at the depths of the Golden Crow Grotto, beating happily, as if to say, now you can go!

"Then I'll go with you!"

Lin Yu laughed, he was convinced of the Human Emperor Knife, he was very curious, there was something in the Golden Crow Cave that could make the Human Emperor Sword so excited.

Then, Lin Yu resolutely stepped out a hundred meters away.

Suddenly, the terrifying temperature of the Golden Crow Grotto surged madly from all directions, squeezing the light into a dangerous arc, but it still failed to break through, and the light stood still.

After confirming that there was nothing to do, Lin Yu took a step forward and continued to move inside.

Along the way, the surroundings were all dark red, and the void was suddenly twisted.

Within a thousand meters of the Golden Crow Grottoes, the surrounding temperature reached a terrifying level, and the dark red color turned pale gold.

Fortunately, someone provided a steady stream of energy to maintain the operation of the light, otherwise at this terrifying temperature, Lin Yu would have been melted into a mess of mud.

Lin Yu's eyes had palpitations, fortunately he didn't act rashly before, otherwise the consequences would be really unimaginable.

In this way, under the guidance of the Human Emperor Sword, Lin Yu continued to go deeper, and at this time he had penetrated to the range of 10,000 meters of the Golden Crow Cave.

The color of the pale gold has also changed to pure gold, which is masculine and rigid, and cannot be described by high temperature.

Lin Yu felt like a sun hanging overhead, and the scorching breath could be felt even through the light.

Soon, Lin Yu came to the end of the Golden Crow Grotto.

Looking up, I saw that at the end, a golden bead was suspended there, and wisps of golden light diffused from the bead, exuding the most masculine and rigid atmosphere.

And what shocked Lin Yu was that above the golden beads, there was also a phantom of a bird.

This bird has three legs, extremely beautiful lines, and is covered with golden light, as if it is the embodiment of the sun.
