There was a roar under the dim sky, and then I saw a sword light brushing by, and the two demon wolves with broken bodies suddenly dissipated, turning into a wisp of black smoke and dissipating into the heavens and the earth.

As the two demon wolves dissipated, a strange aura poured into the body of the young man who had killed it.

The young man inhaled this strange vitality and immediately felt that the vitality in his body was much stronger, and when the heart palace introduced these two breaths, there was a change again, and the blood flowing in his body flowed even faster.

The young man noticed that his body seemed to be transforming, and hurriedly returned to the cave he had found before, sat cross-legged and sat down cross-legged, and the "Heaven and Earth Sutra" in his body was running, allowing the blood to flow along the route on the "Heaven and Earth Sutra".

This young man was Ling Yun who was brought by Ning Fan to practice, Ling Yun had been here for a few days, and Ning Fan did not tell Ling Yun what the place was.

A few days ago, at Ling Yun's request, Ning Fan took him here.

The dead air here is very thick, and because of these dead gases, some long-dead demon beasts and cultivators have turned into zombies and wandered in the dim sky.

I don't know what has happened to the corpse qi in the bodies of these zombies in the perennial wandering, and they have condensed an extremely special aura, which Ling Yun doesn't know what this aura is, but he knows that this aura is very helpful for cultivation.

It is also because of the help of this aura that Ling Yun has broken through the third level in a row in just a few days, and at this moment, Ling Yun is breaking through from the fifth level of qi refining to the sixth level of qi refining, as long as he breaks through the fivefold level of qi refining, then he will usher in a qualitative change.

The process of breakthrough was very smooth, the blood in his body had been running in his body for seventy-two weeks, and the vitality in the heart palace had also become much thicker, and he believed that he would soon be able to break through to the sixth level of qi refining.

With the passage of time, the impurities in Lingyun's meridians, muscles, bones, and five organs have been eliminated.

"It's time for the sixth level of qi refining." Ling Yun opened his eyes and muttered. Washing the scriptures and burning the bones is the benefit of breaking through the sixfold qi refining, removing the impurities in the body and making the body more pure, and the cultivation in the future will be much smoother.

While Ling Yun was still feeling the changes in his body, a roar came from the depths of the barren forest, and this roar resounded through the heavens and the earth, shaking the mountains and forests.

It's been a few days since I've been here, and Ling Yun is no longer frightened when he hears this roar at this time of day, but is just curious about who the owner of this roar is.

He had already instructed him when he brought him here not to go deep into the Netherworld Forest, and this was the first time he had seen him with such a solemn expression. So despite the fear, there is still a hint of curiosity in my heart.

The roar didn't last long before it dissipated, and seeing that the roar dissipated, Ling Yun took out a Confucian book and looked at it.

If it weren't for the fact that the master had made him comprehend Confucianism and Taoism in the early years, and made him have the protection of the vast qi, then perhaps he would have been invaded by the death qi and turned into wandering in this netherworld forest like the group of zombies outside.

In the forest outside the cave, there were constant roars, and the darkness of the Netherworld Forest at night was a little terrifying.

The next morning, the Netherworld Forest was as dark as ever, but it was much brighter than the darkness of the night.

Ling Yun woke up from his cultivation and simply washed with the spring water flowing in the cave, in fact, as a cultivator, it didn't matter much even if he didn't wash, but it was habitual.

Ling Yun simply ate some wild fruits in the cave, which can be regarded as filling up yesterday's consumption.

The Netherworld is full of rotting zombies and dead poison fruits, but there is something clean left in this cave.

After replenishing the consumption, Ling Yun walked out of the cave with his sword and started another day of hunting.

Ling Yun walked out of the cave and instantly hid his breath, this method of hiding was taught to him by Ning Fan, the zombies in the Netherworld Forest are very sensitive to the breath of the living, if he accidentally reveals his breath, then he may be besieged by the zombies in the forest.

Luck may even lead to some intelligent high-level zombies in the depths of the forest, so Ling Yun will hide his aura well every time he goes out, which not only avoids the zombies in the forest, but also helps him hunt zombies.

This time, Ling Yun did not follow the previous route, but went straight to the depths of the forest, and now that he had broken through the sixth level of qi refining, the effect of those low-cost zombies on the periphery of the forest on him had become weak.

Therefore, Ling Yun was going to the depths to find more advanced zombies, so that his cultivation speed could be faster, and secondly, he could hone his body skills and swordsmanship.

Lingyun moved very lightly and quickly, quickly searching for his prey in the forest.

Suddenly, Ling Yun sensed a dangerous aura coming from front of him, and the ground was shaking slightly, and the frightened Ling Yun hurriedly hid his body and cautiously groped ahead.

The closer I got, the stronger the vibration became, the more chaotic the airflow became, and there was a constant roar in my ears.

Ling Yun carefully hid in the barren forest, only to see two huge monster beasts and zombies fighting each other in front of him, one was huge, looking like a brown bear on the earth, but it was more fierce and huge than the brown bear, and there was armor in his body.

The other was shaped like a snake, but it was larger than a python, with a turquoise body and scales as hard as diamonds.

"The Three-Pupiled Python and the Iron-Armored Demon Bear!" Ling Yun recognized these two demon beasts and said in surprise.

Even though the two giant beasts were dead, the furious aura they exuded still made Ling Yun a little uncomfortable.

These two demon beasts should have been fourth-order demon beasts before they were alive, so even if they had been dead for a long time, their physical bodies were still very intact, and they seemed to have their spiritual wisdom emerged.

The two demon beasts are already about to break through the fifth order, as long as they can devour each other today, they can break through smoothly and devour each other, this is the nature of the demon beasts, even if the corpse is dead, they will still pursue their nature and act, not to mention that the two demon beasts and zombies have already had a weak spiritual intelligence.

Under Ling Yun's gaze, the first to act was the iron-clad demon bear, only to see the demon bear's claws waving, towards the blue scale three-pupil python slapping fiercely, this grab brought a "whirring" sound of breaking the wind, and Ling Yun was shocked when he saw it.

In the face of this oppressive claw, the blue-scaled three-pupil python did not have the slightest fear, but the snake tail flicked and collided with this empty claw.

The snake's tail collided with the bear's claw, and the powerful qi wave shook off the dead wood around it, and cracks in the earth appeared under the two beasts.

Ling Yun watched the battle between the two beasts and regained his understanding of the strength of the demon beast's physical body.
