Yuan Dan is formed by the convergence of heaven and earth Yuan Qi, condensing from qi into liquid, and then compressing Fang into Yuan Dan, the process is extremely slow and difficult.

Many people with low qualifications, once they break through from the foundation building to the early stage of Yuan Dan, they will have hundreds of years of longevity, but when the longevity is approaching hundreds of years later, there are still many people who cannot break through to the Yuan infant cultivation, which shows the difficulty of condensing Yuan Dan to the Great Perfection.

Once you become a Yuanying Monk, you can have an extra thousand years of longevity out of thin air, and you can impact that extremely rare spiritual realm, and each realm can increase the longevity for a longer time, but the difficulty is also doubled.

But no matter what kind of realm, once Shouyuan comes to an end, it is the day of the reincarnation of the Heavenly Dao, no one can be an exception, the shadow of death is like an invisible whip, whipping everyone to grit their teeth to go to a higher level, but at the same time there are more terrifying calamities, and the road ahead is endless.

In this world, no one will be allowed to live with it!

Han Shi beckoned, and the pigeon-egg-sized Yuan Dan drilled out of the bones, flew into his hand, and a stronger spiritual sense wrapped Yuan Dan heavily, and after a long time, Han Shi's face became solemn.

There is not much Yuan Power left in this Yuan Dan, but Han Shi saw some of the memories of the skeleton before his death, the picture is relatively messy, and from the perspective of the skeleton before his death, it seems that he was in a beautiful place before he died.

There, it seemed that everything had become extremely beautiful, this person could feel his own strength like a fairy, and with a wave of his hand, he had the power to change the stars, he was so proud, he controlled everything, even everything he longed for and regretted the most, and it was all realized in front of him with a wave of his hand, he was ecstatic, desperate to use his magical powers, even if he used up the last trace of life.

Until finally, in extreme joy, he finally lowered his hands slowly, slowly closed his eyes, and everything disappeared into darkness.

Han Shi's skin was numb, and he inadvertently took two steps back, his spiritual sense dispersed, and Yuan Dan, who was already on the verge of collapse, lost the support of his spiritual sense, and suddenly collapsed and turned into a ball of golden light, and the memory of the skeleton scattered away.

In this person's memory, what he saw was full of beautiful meanings, all the things that made the person who was alive excited about the bones, but in the end, it made that person pay for his life.

Han Shi's eyes flashed, this matter should be an illusion if nothing else, but this illusion seems to be able to see through people's hearts.

Han Shi's heart was cold, and a wisp of sadness rose, the skeleton was also a flexible person before his death, and he had already understood soon after entering the illusion realm that everything in front of him was illusory.

But this person chose to deceive himself, even before death, this person still has the opportunity to leave from this illusion, the way to leave is very simple, as long as you destroy those illusionized people and things with your own hands, you will leave naturally, but this person, in the end, chose to let himself die in extreme joy, not so much, this person died in the illusion, it is better to say that this person died in his own hands.

Han Shi looked at the bones in a daze for a long time, and sighed lightly, his sorrow was not only for the death of this person, but also because of himself.

Han Shi didn't know if he was like the bones before his death, and fell into that extreme beauty, whether he would also choose to die in happiness like the bones.

All this, he was not sure.

If his father and mother appear in front of him again, will he give up everything and return to the good past, if all this gives him a chance to choose, and the price is his life, will he choose so.

Han Shi's heart trembled, turned around, and continued to walk towards the cave without looking back.

Along the way, bones like the first one appeared from time to time, and the magic weapons near these bones were all fragments, the storage bag was long gone, this cave was not hidden, presumably there were many monks who entered this cave, and it was normal that the storage bag was not left, but the monk bones that appeared one after another made Han Shi feel a little more vigilant.

Of these bones, only a few died in the fight, and most of them were like the first skeleton, with a smile of satisfaction on their faces, apparently, they also died in the phantom calamity.

From these bones, Han Shi could see that the deeper he cultivated, the more profound he became, and the bones lying flat in a corner not far in front of him were at least in the late Yuan Dan period, which was quite different from the middle Yuan Dan period of the first body, Han Shi's eyes looked calmly at the crooked cave, as if a big mouth was waiting to be devoured.

"All of this is inseparable from that huge turtle-like creature. Han Shi said secretly in his heart.

Illusion, these monks are all dead in the illusion, I don't know if this illusion is related to the illusion of the mutation, Han Shi pondered a little, and had a guess.

According to common sense, the ordinary cave will be dark after walking into dozens of zhang, but the cave in front of him is not so, he has walked into thousands of zhang, although it is not as bright as day, but there is also a hazy glimmer of light from the surrounding cave walls, all the way, I am afraid that it will always be like this until the end, there must be a demon when things go wrong, and this cave wall is also a part of the mountain.

From the very beginning, Han Shi was jealous of this giant peak, and this jealousy had no reason, it was completely a feeling.

Han Shi stretched out his hand, pressed on the cave wall, a trace of Yuan Force suddenly emanated from his palm, and infiltrated towards the back of the stone wall, for a long time, he slowly withdrew his palm, his eyes showed a strange light, there was nothing peculiar about this stone wall, but in it he noticed the existence of the power of thunder, his Yuan Force penetrated into the stone wall but not a little bit, he could not inch in, he could feel that there was infinite thunder force in the depths of this stone wall, he did not rashly increase the Yuan Force to break through the barrier, but retracted the Yuan Force and stood quietly, falling into thought.

Thunder power is born in heaven and earth, and it is also dissipated in this heaven and earth, and the supernatural cultivators who cultivate thunder tricks can send out thunder and lightning with their own strength, but this kind of thunder is only the thunder of people, not the thunder of heaven and earth.

The thunder of heaven and earth, the most common is the thunder and lightning when it rains, rumbling to show the power of heaven and earth, followed by the thunder tribulation, its power is stronger than the thunder of the monk.

The thunder of heaven and earth is difficult to absorb, and it is also difficult to store, so there are some of them in the thunder sound stone.

Now. Han Shi saw the existence of the thunder of heaven and earth again in this giant peak, this kind of storage is like a sponge absorbing water, every bit of water is sucked into it, but it doesn't look like it can be seen at all, only when it reaches the limit of absorption, the water that is inhaled will show traces.

This giant peak is thousands of miles in circumference, it is unimaginable, if it is full of thunder power, what kind of power it will be, Han Shi only felt that his scalp was numb, but at the same time, there was a trace of excitement in his eyes, the brilliance of the cave was the glimmer of the thunder light emitted after passing through the cave wall.

The real name of this giant peak should be Thunder Mountain.

The boundless sea of clouds, contains endless thunder and lightning, this thunder mountain is like the iron stake on the side of the thundercloud island, has been absorbing the power of thunder, the formation of the thunder stone must be related to the thunder mountain, this thunder mountain has absorbed a large amount of thunder power for so many years, and the water is full of overflowing truth, part of the thunder power overflowed, deep underground contaminated in the stone, after a long time of fusion to form the thunder stone.

If you can get some of the thunder power from this thunder mountain, even if it is only a very small part, it will be enough for Han Shi's Nine Thunder Technique to break through again.

The cobblestone will also gain enough thunder power to break out of its shell.

This huge cobblestone has absorbed the essence blood of the black dragon, and Han Shi can feel a long-dormant power in it, this power has been sealed for a long time, and once it is rushed out, it will definitely have a strong power and become a great help to Han Shi.
