Early in the morning, Lin Yun and the crane opened their eyes in the cave, after a night of healing, the crane's face improved, and the little girl Mu Linghui was also asleep on the stone bed, and the cold on her body finally survived.

"Come on, slow down!"

Lin Yun helped the crane up and sat on the stone bench, her body was still weak at the moment, and she didn't even have the ability to move.

"Brother Lin, where is this?"

The Immortal Crane looked at the surroundings and asked Lin Yun.

"Well, it's a deserted cave, opened by cultivators!"

Lin Yun replied.

"Oh, let's see if it's left by some senior!"

Lin Yun said with a smile: "This cave is so big, it is clear at a glance, there is nothing to check!"

Generally, if you inadvertently break into some cave secret realm in the immortal cultivation realm, you must not be in a hurry to exit, take two steps forward, maybe you will have a different harvest.

At this time, everyone in the immortal cultivation world knows a stalk, who doesn't want to fall into the cliff and not die, but also obtain peerless magic skills.

"Okay!"

Xianhe also had some of these thoughts, but when he saw Lin Yun laughing at her, he was suddenly a little embarrassed.

"Look, this cave is destitute, but there are no treasures!"

In order to take care of the crane feelings, Lin Yun still knocked on the stone wall of the cave decently, and probed with his divine thoughts.

Only at this moment, he walked to a place, and the divine thoughts were abnormal, if it was the cultivation of the previous life, he would definitely not be able to perceive it, but his memory here was the memory of the Immortal Emperor, and this subtle feeling was immediately captured by him.

"That's not right!"

Lin Yun's brows furrowed.

"What's wrong?"

Xianhe watched Lin Yun suddenly become serious, and also asked suspiciously.

"This is not the right place!"

Lin Yun stretched out his hand, the star yuan in his hand surged, and one by one the mysterious runes surrounded his hand, only to see him press his hand towards the ground, and then he felt it carefully.

A moment later, suddenly, he opened his eyes, with surprise on his face, and said, "There is another mystery down here, the qi machine is covered by a formation!"

"Really?"

The crane also had a happy expression on his face.

"However, this formation is a bit complicated, and it will take some time to crack it!"

Lin Yun spoke.

"It's fine!"

The crane replied.

Since there is another mystery below, and the formation level is relatively high, then it is definitely thought that the master stayed, so the two of them saved their minds to take a look.

So, Lin Yun began to crack the formation.

Fortunately, he has the memory of the Immortal Emperor, although this formation is mysterious, it has not been able to stump him.

After a whole day of cracking, it wasn't until night fell that Lin Yun finally cracked this formation, and bursts of light lit up on the ground of this cave, and then the entire ground turned into a starlight channel, leading straight down.

"That's it!"

Lin Yun opened his mouth to the crane who was closing his eyes to heal his wounds, and at this time, the little girl also came over and looked at the starlight channel in front of her with a look of surprise.

The three of them no longer hesitated, and Lin Yun took the two girls and escaped into the underground passage.

Immediately after, the light flashed, and the three of them had already arrived in a cave.

Surrounded by the rising mist, the cave is huge, a tail of golden koi swims in the deep pool in the hole, and the green lotus blooms in the pool, and the glow is thousands.

This is actually a rare spiritual pool, and all the spiritual liquid flowing in it makes the entire cave house full of spiritual energy, and it looks like it has entered a real immortal blessed land.

The three of them jumped to the deep pool and came to the main hall of the cave, the whole hall was also built quite luxuriously, the dome was full of light, and the bright gold bricks were paved on the ground.

The two of them showed joy on their faces, cultivating in this kind of cave mansion was at least several times more than that outside, and it was also very helpful for the injury of the immortal crane.

The three of them began to investigate the cave and confirmed that there were no safety hazards, and then they were relieved.

I don't know which master left the cave, there are a lot of treasures in it, and a large number of various precious medicinal materials are placed in a space stone room, which are all good materials for refining Xuandan.

The other stone room was equipped with a lot of spiritual weapons, although the grade was not too high for Lin Yun, but they were all good treasures.

Seeing the scene they were in, both of them felt that they had gained a good harvest, so they decided to stay here for the time being.

The two of them began to cultivate on this ground, which was no less than a holy place for spiritual energy healing.

Three months later, the Immortal Crane's internal injuries had fully recovered from this aura and the elixir refined by Lin Yun.

It's just that the dantian injury, but there is no way, Lin Yun can refine the elixir to treat the dantian's injury.

However, although there are many precious medicinal materials, they are still lacking as the main medicinal materials, so they have not been able to refine the elixir and cure the crane.

The little girl also embarked on the path of cultivation under the teaching of the crane, and this kind of aura is so abundant, it is the best place for her to start cultivating.

Lin Yun also refined an elixir that could greatly reduce the pain caused by the little girl's cold.

The immortal crane on the side was surprised to find that Lin Yun's alchemy technique was far above her, the head of the immortal medicine sect, which made her even more impressed with Lin Yun.

Not only can he crack such a mysterious formation, but he also has such a one-handed alchemy technique, and his strength is even stronger than that of a late-stage congenital pill.

This made her full of curiosity about Lin Yun, she didn't know what this guy was going through, he looked so powerful when he looked young.

During this period, Lin Yun also refined a lot of pills for his own cultivation, and his strength improved by leaps and bounds, and he had already touched the threshold of the pill.

I don't know if it's not so easy to get a pill, there are three stages of the pill, that is, the fake pill period, the Yuan Dan period, and the Jindan period, only when you get out of the fake pill, you can be regarded as stepping into the realm of the knot.

At this time, I saw him sitting on a huge lotus leaf in the spiritual pool, his eyes closed, and he was impacting the fake pill stage and condensing the fake pill.

However, the exercises he practiced caused him to be different from ordinary immortal cultivators, and what he condensed was the False Star Pill, the Yuan Star Pill and the Venus Pill.

His entire Dantian Star Sea will have a big explosion again, and all the stars in the entire Star Sea will gather together, so a star core will be formed, which is also a false Star Pill.

The star core continued to compress and condense, turning into silver, that is, it became the Yuan Xing Dan, and finally turned into gold, becoming the Venus Dan.

And ordinary immortal cultivators can only truly step into the ranks of immortal cultivators only when they condense the inner pill, and from then on, the sword will fly, no problem.

Of course, this process requires the energy of heaven and earth very much, and the exercises he practiced caused him to need more energy than ordinary immortal cultivators.

At this time, he coiled on this lotus leaf, preparing to use this pool of spiritual liquid to impact his false pill stage.

I saw that he first absorbed all the pills he had refined in the past three months, and then converted all these energies into Xingyuan, filling the entire sea of stars, and after doing this, ten days had passed, and then he took out an inner pill and inhaled it into his body, this is the inner pill that drilled the ground flame rat, and it has come to the middle stage of the Dan, that is, the Yuan Dan stage, the energy is huge, and it is a rare tonic.

After absorbing this demon beast Yuan Dan, it took him half a month, and during this time, his sea of stars was gradually changing, the entire sea of stars was already tumbling like a huge wave under the flood of energy, and those stars were entering the ships in the huge waves, constantly rising and falling in the sea of stars. In this sea of stars, there is a vortex point like a black hole, which continuously pulls the star energy in the sea of stars towards this vortex, and is constantly converging.

After all the energy is pulled in, when enough energy is pulled, it will finally condense into a star core.

I saw that Lin Yun continued to control the vortex to gather all the energy in the sea of stars, and at the same time, the Great Heaven Star Sea Technique was fully operational, and all the seven pores opened, forming a suction force and began to absorb the spiritual liquid in this pool.

I don't know how much spiritual fluid there is in this pool, even Lin Yun can't detect it with his divine thoughts, so he is sure that he can break through the Dan Stage with this move.

And the crane was on the side to help Lin Yun protect the Dharma, and after a few months of getting along day and night, the two seemed to know each other's intentions, but this layer of paper had not yet broken through.

Especially after the two of them have formed a heart, every time they heal, you have me, I have you, so that the relationship between the two has grown by leaps and bounds.

There was no time for cultivation, Lin Yun didn't know how long he had been sitting on this lotus leaf, and the pool of spiritual liquid had already sunk into it a lot, like a milky way waterfall, pouring into Lin Yun's body, leaving no room for him to absorb it all.

This kind of phenomenon made the immortal crane amazed, but when she broke through the Dan stage, she didn't need such a lot of energy.

This Lin Yun's body was like a black hole that never ended, constantly devouring the energy of heaven and earth.

With the devouring of such a huge amount of energy, I am afraid that when it reaches the Yuan Infant Stage, the Heavenly Tribulation suffered is at least several times more than that of ordinary immortal cultivators.

Lin Yun didn't know what the immortal crane outside thought, he was immersed in endless cultivation here, he didn't plan to directly condense the fake star pill here, he was going to absorb all the weather spiritual liquid in this pool, and then try to condense the Yuan Star Pill, which is also the Yuan Dan, if the ordinary immortal cultivator knew his actions here, he would definitely think that this person was crazy.

The path of cultivation is extremely difficult, and a short walk may lead to a catastrophe, who can act like this, if something goes wrong, there is no difference between looking for death.

And Lin Yun dared to do this, not because he was not afraid of death, but because he had thousands of years of experience as an Immortal Emperor and knew how to condense this kind of Yuan Dan, which was his biggest reliance since his rebirth.

Time is passing step by step, and in the blink of an eye, another three months have passed. Under the guidance of the Immortal Crane, the little girl's cultivation has already entered the middle stage of Qi refining.

Of course, to have such a fast cultivation speed, in addition to the abundant spiritual energy in this cave, there is also her almost demonic cultivation talent, which is the supreme benefit brought by the Nine Tribulations Absolute Vein, in addition to the benefits of inevitable death.

Finally, the center of the vortex in Lin Yun's body, like a huge cosmic black hole, incorporated all the energy in the sea of stars into the vortex, and then continued to compress and condense under Lin Yun's manipulation, like pinching a flour ball, shrinking it as much as possible.

With such compression, half a month has passed, and Lin Yunyi is eyes closed tightly, sitting cross-legged on the lotus leaves.

And that pool of spiritual liquid had already been incorporated into Lin Yun's body without a drop, turning into endless energy.

At a certain moment, I saw that the vortex shook suddenly, and suddenly sent out a sudden explosion, causing his entire sea of stars to tremble, constantly expanding outward, becoming more and more infinite.

At the same time, a huge silver star appeared in his body, occupying the center of the sea of stars, making the entire sea of stars focus on him, constantly rotating.

Lin Yun's mind, which had been immersed in it for several months, finally showed a touch of joy, and he knew that the Yuan Dan period had been completed.

"Boom!"

At this moment, he opened his eyes suddenly, and a bright silver light in his eyes turned into two rays of light, shooting straight out.

Instantly hit the cave and shot through the cave wall directly.
