With each step, the dead air became more and more intense, and in his heart, it turned into an invisible pressure, making it difficult for Han Shi to move.

Three hundred zhang forward, Han Shi's face became pale, the death qi here has reached the limit, if ordinary people are here, they will immediately lose their minds under the impact of this death qi, become a walking corpse, and eventually, they will also turn into a part of this mountain of white bones.

At this moment, there was a trace of unusual aura in this thick dead air, Han Shi's eyes lit up, and he could feel that the seven-pointed bluestone located in the dantian seemed to sense something, and woke up from the silence, slowly absorbing that breath.

"Isn't that ....... Evil spirit?" Han Shi said secretly in his heart.

The so-called evil qi is formed by the condensation of a large amount of dead qi, but among them, there must be the killing intent left by these dead people before their deaths.

This evil aura will not be extinguished for a long time, quietly lurking in this mountain of white bones, until countless years later, it will gradually fade between heaven and earth.

What the heptagonal bluestone absorbs is a wisp of evil energy.

As Han Shi got closer and closer to the top of the mountain, the evil qi circling around also became stronger, and the process of absorbing the evil qi of the seven-pointed bluestone did not need Han Shi's distraction to pay attention to it, this was his natal stone, and it had its own spirituality.

For a long time, Han Shi's figure appeared on the top of the White Bone Mountain, where there was no dead air, and all around was evil.

"Since the hexagonal bluestone takes the initiative to absorb this evil qi, it must be of great use, so I will help it. Han Shi's eyes showed determination, in addition to helping the seven-pointed bluestone, he could feel that the limit of building the foundation had arrived.

Maybe it's right here, stepping into the realm of Yuan Dan.

Han Shi sat cross-legged, motionless, quietly absorbing, evil qi followed the pores, burrowed into Han Shi's body, meridians, blood, and five internal organs, every place was filled with evil qi.

Previously, the absorption of evil qi was directly absorbed by the heptagonal bluestone from the dantian, and did not enter the whole body, so I did not feel the power of this evil qi deeply.

At this moment, as soon as the evil qi entered the body, it was like ice, reaching the bottom of Han Shi's heart, making his eyes reveal an indifferent and ruthless meaning, like the eternal ice and snow domain.

His person, at this moment, and this mountain of bones turned into a whole, if you look from the bottom of the mountain, what you see is no longer a green shirt, but a white bone, sitting on the top of the mountain, becoming a part of this mountain of bones.

Gradually, with the absorption of Han Shi, the evil qi that had been hidden in the White Bone Mountain for countless years emanated from the mountain and headed towards the top of the mountain, gathering in large numbers above Han Shi's head, and then slowly rotating up, forming a vortex like a funnel.

At the bottom of the funnel is Han Shi.

A powerful coercion, born out of thin air, followed Han Shi's heavenly spirit, and went straight into his body, almost instantly, it reached Han Shi's limit, if it was one more point, his physical body would inevitably collapse and turn into pieces.

Han Shi's face was wrinkled under the coercion, but there was a fire in his eyes.

This coercion is like a gift from heaven, which has changed the vitality in Han Shi's body, and Han Shi's cultivation has reached the peak of foundation building, and one step further, it is the realm of Yuan Dan.

Different from building a foundation, condensing one's own Yuan Dan is to further condense the Yuan liquid that is transformed into a solidified Dan-like thing, which is originally called Yuan Dan.

This process of condensation, for ordinary foundation building monks, takes decades before they have a chance of success.

But right now, Han Shi clearly felt that in the dantian, under this powerful pressure, the yuan liquid was slowly compressed, condensed, and moved towards the direction of solidification step by step, this kind of change, under the spiritual sense, was extremely obvious.

At the same time, his physical body has also been tempered a lot, as if he has been tempered again.

A large amount of evil qi entered the body and was absorbed by the hexagonal bluestone, and gradually, although the appearance of the bluestone has never changed, in Han Shi's view, there is a sense of facing life and death, which makes people faintly creepy.

This bluestone seems to have become a symbol of killing.

The funnel composed of the evil qi gradually faded, and the evil qi that had been precipitated in this white bone mountain for countless years was absorbed by the heptagonal bluestone.

Suddenly, the heptagonal bluestone flashed and submerged into the yuan liquid.

Han Shi frowned, the natal stone was integrated into Yuan Dan, whether this matter was a curse or a blessing, he had no way of knowing, and in the memory of the inheritance, he never mentioned it.

It can be said that every choice of Han Shi is completely new, whether it is good or bad, in the end, only he will know.

And now, since the natal stone has made such a choice, then just like his choice, melt the stone into the pill, and see what happens.

The speed of the Yuan liquid is getting faster and faster, but it still does not make a sound, and it rotates at a high speed silently.

Three days later, suddenly, in Han Shi's dantian, there was a cyan light Dasheng, shining in all directions, after the light, there was a cyan Yuan Dan floating in it, and strong fluctuations emanated from the Yuan Dan, and instantly spread throughout the whole body.

A wave that belonged to the Yuan Dan monk came out from Han Shi's body in all directions.

And in the depths of this Yuan Dan monk's breath, it seems that there is an incomparably powerful giant beast hidden deep in it, which makes people subconsciously feel respectful of Han Shi.

It only took three days to succeed, and this speed is extremely fast.

Feeling the power emanating from the cyan Yuan Dan in the dantian, Han Shi smiled slightly at the corner of his mouth, is this what the Yuan Dan monk feels.

Han Shi felt that as long as he wanted, he could draw the powerful Shi Yuan Force from Yuan Dan at any time, and now he could compare it to the full force of the previous blow with a punch in his hand.

At this moment, it seemed that he was extremely lucky to be able to fight the whitefriar, and to be able to win the battle.

If it weren't for the fact that he had cultivated the Dingtian Stone Technique, it would have been impossible for him to defeat the Yuandan monk by virtue of his foundation building cultivation.

This gap, after Han Shi reached the Yuan Dan realm, it was really clear, at that time, he could kill the other party, all relying on the power of gray stone, to reverse the situation, at that time, the demon beast was extremely strong, now that I think about it, I am afraid that it is not much better than this black-faced man.

Since embarking on the path of cultivating immortals, along the way, although his intelligence and perseverance are beyond ordinary people, and he has gained a lot of opportunities, many life and death crises have completely relied on gray stones to get to the current place.

This gray stone has been accompanied by Han Shi for many years, but he has never been clear about what it is, except for a large space, and the Dingtian stone recipe, the gray stone is still extremely mysterious in Han Shi's eyes.

If he wants to uncover the secret of the gray stone, I am afraid that his cultivation needs to reach an extremely high level before he can have the qualifications to pursue and explore.

Han Shi slowly recovered his mind and opened his eyes, his Yuan Dan was not the usual gold, but cyan, which did not match the record in the classics of Xuanyangmen.

It's just that there are exceptions to everything, and there is a miscellaneous book that specifically records the color variation of Yuan Dan.

Among the 10,000 people, 9,999 people are golden, of which Ming gold is the most common, accounting for about seventy percent.

There are fewer pale gold, accounting for about two and a half, and the monks who form this color Yuan Dan are often more excellent, and the people who cultivate to be extraordinary will occupy a relatively high position in their respective sects.

And the remaining half of the percent, will show a dark gold, this color of the Yuan Dan, extremely rare, the people who have it, most of them are people with a very high status in the future, and this kind of monk, no accident, cultivation will be limitless.

According to the miscellaneous records, most of the people who possessed the Dark Golden Yuan Pill later became infant monks, except for a very few who died in accidents, at least they also became spiritual monks, and the highest one later reached the Mahayana of the three realms of the vehicle.

Mahayana monks, even if they are placed in the entire Northern Xuanxing, are only a handful, belong to the top few people, have powerful power, and lean towards one side.

Among the ten thousand people, it is not the golden one, but also the most special one, not that special will bring any special luck, in the record, for countless years, there are four colors: black, white, purple and blue.

These four kinds of Yuandan monks have a common characteristic, that is, in the Yuandan realm, they are extremely strong and invincible, but when they hit the Yuanying realm, they all died in the heavenly tribulation, as if there was a force in the underworld, and they didn't want such monks to grow up.

A faint light flashed in Han Shi's eyes, so it seems that the cyan of his Yuan Dan is the fifth color, which is not yet in the record.

The four Yuan Dan monks who died in the Heavenly Tribulation were also different from gold, but all this did not mean that his fate would be the same.

He never believed in fate.

Han Shi's gaze fell on Qingdan, and a strange feeling rose in his heart.

It seems that it is not Yuan Dan, but a cyan egg, which is pregnant with something, and the moment it is born, it will be the time to amaze the world.

This matter is still far away, don't think about it for the time being, and now that he hasn't stopped yet, Han Shi slowly got up, ran Qingdan, and felt the death air that permeated the surroundings again, Han Shi's face was calm, and he didn't walk down, but sat down cross-legged again, to consolidate the cultivation of the early stage of Yuan Dan.

Feeling the continuous rise of Han Shi's breath until he broke through, the middle-aged man in black stood outside the hall, and his eyes showed surprise, "I can actually marry on the White Bone Mountain, a blessed person." ”

The black-faced man always sat on the top of the Golden Mountain, not paying the slightest attention to Han Shi's knotting, and still meditating on his own, his hands kept playing peculiar formulas, and there were words in his mouth, but the voice was so small that it was impossible to hear what he was saying.
