In the abandoned wasteland, in the deep and bottomless nameless cave, there are two figures groping cautiously.

Gu Fan always felt that there was an inexplicable call coming from the depths of this cave, and in this deep darkness, it seemed a little weird. Gu Fan listened attentively, the voice came and went, sometimes strong and sometimes weak.

He pulled Ke Yixue and asked softly in her ear if she heard anything. "Yixue, it seems that some strange sound is coming from the depths of the cave!"

However, when Ke Yixue heard this, she was very puzzled, looked at Gu Fan blankly, shook her head and said.

"The sound of calling? Gu Fan didn't, did you hear it wrong? Why did I only hear the whistling sound of the wind flowing in the cave, did you hear it wrong?"

Hmmm! Gu Fan's heart was shocked, he heard it, but Ke Yixue didn't hear it, could it be that he heard it wrong? But it shouldn't be, not only this call, but even his body seemed to feel like it was being pulled underground!

Gu Fan shook his head and laughed at himself, anyway, now that the exit of the cave is blocked, the two of them can't get out. You can only go to the underground of the cave to find out if there is any other exit.

The entrance to the cave is extremely narrow, about the width of two people side by side, but the further down it becomes, the wider it becomes, and after walking to a depth of about a few tens of meters, you find that the passage that has been going downhill has become extremely flat.

The bottom of the cave would actually be hollowed out! What greeted Gu Fan's eyes was pitch black, as if there was no darkness today. But fortunately, Gu Fan was prepared and took out the fire fold from his arms.

He lit the fire fold, and then reached out to look for it, but the look on Gu Fan's face once again showed shock. This... In the depths of this cave is an untold square!

There are snow-white dry bones everywhere in this square, and the further you go inside, the more dry bones there are! There are demon clans, human terrans, and unknown beasts and monsters!

Some of them are complete skeletons, some of them are scattered, and all the dry bones have turned into loess! What the hell is this place? Why are there so many dry skeletons?

This doubt deeply surfaced in Gu Fan's mind, Ke Yixue beside him had never experienced such a terrifying picture as a pot, his body was a little trembling, and he was very scared in his heart.

She was close to Gu Fan, and dragged Gu Fan vigorously with her broken jade arm, for fear that he would suddenly disappear, leaving her alone in this cave that did not see the light of day all day long, and was extremely dim and accompanied by white bones.

Gu Fan felt his arm tighten, and saw Ke Yixue's face nervous and frightened under the light of the starry light of the fire fold, which looked extremely pitiful.

He couldn't help but hold her cold little hand and said to Ke Yixue in a firm tone. "Don't be afraid, we'll get out of here with me, trust me!"

Ke Yixue looked up at Gu Fan's firm eyes, her hand was held by Gu Fan's big hand covered with calluses with a knife all the year round, and the uneasiness and fear in her heart seemed to be much more indifferent.

The two of them didn't say much, everything was in one look. Gu Fan pulled her and slowly pushed away the pile of bones, and continued to move forward slowly and cautiously.

It didn't take long for Gu Fan to find that there was a huge altar in the middle of the dim square in front of him! How could there be an altar here, Gu Fan and Ke Yixue looked at each other.

The two of them slowly walked to the altar, and at the four corners of the altar stood a red flag of unknown material, and on the red flag there were runes of unknown nature.

Hmm? These runes seem to have been seen somewhere! Gu Fan flashed this thought in his heart, where was it? At this time, Ke Yixue beside him was a little surprised.

"Gu Fan, look at these runes, are they very similar to the runes of the Heavenly Dao shackles on your body!"

When Gu Fan heard this, his expression was shocked! Yes, these runes were actually very similar to the runes of the Heavenly Dao shackles revealed in the knots on his body. No, it's exactly the same!

What exactly is this altar sacrificing? Why did even the Heavenly Dao runes come out! After all, Gu Fan and the others were teenagers, and the newborn calf was not afraid of tigers, and they were extremely curious.

Gu Fan handed the fire fold to Ke Yixue and asked her to wait here, and then walked up to the altar step by step, wanting to find out if there was a way to get out on the altar.

When Gu Fan took the first step, the previous resistance of the cave came out again! He didn't have time to stand firmly, and he stumbled and almost fell on the first step of the altar.

Ke Yixue, who was watching him not far away, was also surprised, but fortunately, Gu Fan stabilized his figure and did not hit the street, he drew an OK posture towards Ke Yixue with one hand, signaling her to feel at ease.

There are nine steps to the altar, which is not too high. But Gu Fan had just stepped into the first step, and the resistance pressure followed.

Although Gu Fan's figure did not stand firm, there was an element of resistance that was invisible and unprepared, but with Gu Fan's unusual cultivation in the middle of the Second Realm, he had such a reaction, which showed that this resistance was not simple.

The first, second, and third steps, Gu Fan stepped up quite easily, until the fourth floor. When Gu Fan had just stepped on this step, he suddenly felt a burst of overwhelming pressure, coming from all directions!

Gu Fan hurriedly used the true qi in the Qi Sea Dantian to continuously move his limbs to share the pressure on his body, and instantly felt that this pressure had been reduced a lot, and hurriedly stepped towards the fifth layer.

Stepping into the fifth layer, the pressure around him became even stronger, and the true qi in Gu Fan's Qi Sea Dantian seemed to be unable to support him to continue moving forward, and the true qi of the dantian was running in the twelve basic veins in accordance with the operation method of the "Mixed Yuan Innate Decision".

Circulating the true qi in his body in the dantian all day after week, Gu Fan protected his true qi and forced the pressure to spread out! Finally, he stepped on the sixth step steadily.

On the sixth floor, the seventh floor, Gu Fan was stepping forward step by step! His delicate face was bursting with blue muscles, gritting his white teeth, and looking fiercely at the two steps above, these were the last two steps!

On the eighth floor of the stairs, Gu Fan's twelve major veins and twenty-four dark veins were all running for weeks, forcing his own potential, and the thought of not admitting defeat struggled in Gu Fan's deep mind.

"Ahh

Gu Fan let out a long roar, suddenly took a big step forward, and resolutely climbed the ninth step. However, the oppression and repulsion of the ninth layer are not at the same level as the previous eighth order!

His front feet were weak, and he didn't stand firmly, and the long steel knife was suddenly pushed to the ground, and he knelt straight on the last step!

For now, Gu Fan has only two ways to choose, either go back and give up climbing the steps, and there is a high probability that he will be buried alive with Ke Yixue under this nameless cave, just like those dry bones, and no one cares about it!

This is not what Gu Fan wants to see! He and Ke Yixue are still young and have dreams, how can they be buried here so easily! Immediately, he thought of the second possibility, which is also the second way!

It is to continue to climb upwards to see if there is a way out of this cave above this altar. This is what Gu Fan wants, the desperate struggle activates Gu Fan!

A fearless momentum erupted from his body, and the Mixed Yuan Innate Determination operated on its own! Twelve great veins, twenty-four dark veins, and thirty-six acupoints were all ignited!

Under the pressure of the pressure and repulsion, the true qi in Gu Fan's body became stronger when it was stronger! The cultivation continued to increase, breaking through the middle stage of the Second Realm, the late stage of the Second Realm, and the Great Perfection of the Second Realm! Only then did it slowly stop.

Gu Fan broke through with the help of the small realm, and the combat power of his body reached an optimal state, and he stood on his knees, and suddenly rose up and walked towards the top of the ninth layer without hesitation!

When Gu Fan stepped smoothly on the altar, the red flags around the altar suddenly raised without wind! As if he had received an inexplicable invisible summons.

No, these are not red flags! Gu Fan, who stepped on the altar platform, looked at it fixedly, and these red flags were blooming with a strange light! Which is this a red flag, these are demonic blood flags!

These blood flags have been soaked in the essence blood of many human races, or demon people, in order to form such a strange color! No wonder, Gu Fan always feels that these blood flags have an inexplicable sense of oppression!

Soaked in so much essence and blood, I don't know how many years, it has been different from ordinary mortal things, and it can no longer be simply measured, in general, these blood flags have become essence!

Of course, in this dark environment, and the cultivation of essence and blood, Gu Fan estimated that there were more evil natures!
