Tianyun Xuan, a relatively elegant name, is located in Tianfrost City, a place where the aura of immortals is very full, and many people in the immortal level of Tianfrost City will choose this place as a place to cultivate.

Even those who have only cultivated in the Mahayana period, when they have abundant spiritual stones, will come here to comprehend the vitality of heaven and earth in order to reach a further realm.

Han Li left the trading hall and passed through the nearby teleportation array, and it didn't take much time to get here, before he walked out of the small room where the teleportation array was located, Han Li already felt an unprecedented immortal aura, flowing around his body like a passion, even if he took a few sips of the rich qi in it, he could also soothe the depressed aura in it.

As far as Han Li's eyes could see, there were countless immortal aura like willows fluttering, more than a dozen unnamed birds flying freely in the sky, and hundreds of strange flowers blooming on the ground, the fragrance of which was even more refreshing, and with the light immortal aura turned into a mist, it was like a supreme fairyland.

At this time, a fifteen or sixteen-year-old, slender woman in her infancy was putting away a small magic weapon in her hand, and walked with an extremely light demeanor, and she asked with a smile on her eyebrows:

"Lord Immortal Venerable, are you here to advance your cultivation or to comprehend the Heavenly Machine?"

One sentence of Lord Immortal Venerable made Han Li's heart suddenly, this is something that only the Immortal Emperor level can bear, but he still smiled slightly and asked back:

"Little girl, is there any difference between advanced cultivation and this Heavenly Enlightenment?"

The slender woman smiled lightly, bowed slightly, and continued:

"Lord Xianzun, of course, this advanced cultivation requires an extremely strong immortal aura, we will choose a suitable place for you to cultivate, and if Lord Xianzun needs to comprehend the heavenly machine, he needs a quiet place, and he doesn't need to pay much attention to other environments!"

Han Li listened carefully, and this fair woman paused for a moment before continuing:

"Of course, whatever specific environment Lord Xianzun needs, we will also try our best to select and cooperate in order to satisfy you, Lord Xianzun."

After hearing this, Han Li knew that he would have to pay no less if he could make such a unique move here, so after a little consideration, he asked:

"Little girl, how many fairy spirit stones are needed for each of these venues?"

The fair woman in front of Han Li immediately began to introduce again:

"Lord Immortal Venerable, our Tianyun Xuan is directly under the Golden Invitation Immortal Palace, and we are heavily guarded, and we can completely ignore the interference of the outside world, even if the Immortal Envoy wants to invade, it is not easy for the Immortal Envoy to invade, as for the Immortal Spirit Stones required for this advanced cultivation, it is ...... every year."

Until this fair woman had introduced all the immortal spirit stones needed in the place, although Han Li's face still did not change, he still felt that his current self was unacceptable, so he still replied with a smile:

"All I need is a normal secluded place!"

This fair woman was also well-informed, so she didn't recommend it anymore because she was very knowledgeable, she simply responded, then turned around and made an inviting gesture, Han Li continued to ask as she walked:

"Little girl, are there really other Daoists advancing here?"

When the fair woman who was walking on the side heard Han Li's words, she immediately lowered her head slightly and said:

"Lord Xianzun, of course you can't advance, if this mountain is really struck by the thunder a few times, we won't be able to do business, but Lord Xianzun, you can condense here to the point where you have a sense and you have to leave, we can also specially select the place for you to be robbed and advanced, you only need to pay the corresponding fairy spirit stone."

In this way, the fair woman and Han Li chatted while walking, and soon crossed a small bridge long enough, walked through several small mountain streams, climbed more than a hundred stone steps, and came to a towering mountain that reached into the sky.

Han Li looked up, and the dense mist turned into immortal aura drifted around the entire giant mountain, and piles of forbidden rune spells faintly flashed and sometimes disappeared.

No wonder there was such a huge mountain, but Han Li didn't see a single thing near it, it was probably due to this layer of prohibition.

In the midst of the clouds and mist, Han Li looked far away and found that there were a lot of houses built in the middle of the mountain, which looked very simple on the outside, but when he saw the text of the spell on it, he was relieved for a while.

Suddenly, near the peak of what Han Li saw, a small fiery red tornado slowly moved in front of a certain house, and under the blue flickering in his eyes, there was a faint invisible fluctuation, but Han Li couldn't see it at a glance.

The fair woman next to her saw Han Li stop, and she didn't have the slightest intention of urging, just waiting quietly on the side, still with a little smile on her face.

Han Li stared at the time of half the tea before he continued to pace the white stone and earth bricks on the ground and walked to a forbidden stone door not far in front of him.

The slender woman who followed unhurriedly next to her had already called out a white jade waist card, and with a slight point, the jade plate burst out a green rainbow and shot straight at a small legal ban on the stone door.

The stone door of this door slowly opened, revealing a large empty hall in front of the person, which was several miles in circumference, but there was not a single person or thing in it.

Han Li swept carefully, there were two small single teleportation arrays on one side of the hall, and on the wall on the other side, there were shining crystal ice cards, the ice cards were arranged in the shape of a ladder, and on these ice cards were marked with the names of the corresponding sequences.

Most of these ice cards had a translucent ice jade texture, and only a few of them had a reddish or bluish color, and Han Li seemed to see something.

When the forbidden stone door was slowly closed, a halo of runes flashed around, and the fair woman gave a salute and said:

"Lord Immortal, according to your needs, please leave a little mark on it to get the corresponding forbidden token, and then hand over the fairy spirit stone to the little girl, and you can go to your cultivation place to comprehend the heavenly machine."

"Make a mark?" Han Li muttered to himself vigilantly.

"Lord Xianzun, this mark will be automatically destroyed when you leave, and there will be no residue, please rest assured, Lord Xianzun!"

The fair woman quickly explained to Han Li, and Han Li immediately picked a room on it, and with a flick of his fingers, a little mark had already shot onto an ice card lower on the wall, and the ice card buzzed for a while, and the aura shook and suddenly took on a light blue color.

Then, a crisp sound sounded, and an emerald jade plaque the size of a palm with two red ribbons flashed in front of the two of them.

As soon as Han Li's palm was raised, his five fingers were slightly bent, and the emerald jade plate was already in his hand, and after a little scrutiny, he handed it to the corresponding fairy spirit stone for the fair woman, and Han Li strode towards one of the two teleportation arrays.

At this time, the fair woman seemed to have forgotten something, and hurriedly reminded:

"Lord Xianzun, you have set a ten-year period, please complete it within ten years or come to renew it, otherwise this Xuan ban will automatically invite you out of Xianzun, please Xianzun must remember!"

Han Li nodded slightly at him, a spell was already embedded in the emerald jade plate in his hand, and the teleportation array then flashed with a flash of inspiration, and Han Li had disappeared from this hall without a trace.

The next moment, in the blink of an eye, Han Li appeared in a small stone house, looking around, he was in a large room with several cultivation secret rooms, as well as a medicine garden, a reception room, and so on.

Han Li closed his eyes and sensed carefully, the immortal aura here was still a little stronger than the place he had just arrived, he nodded slightly, and walked out of the small stone house.

After opening all the prohibitions on the emerald jade card, Han Li also added several prohibitions before transplanting some of the medicinal herb strains that had previously sent the storage ring into the medicine garden, and also leaving a wisp of divine thought to be handed over to the palm bottle to plant, and the crab Dao people, fire beards, and others were also ordered not to enter the medicine garden, so they each found a secret room to cultivate, and Han Li also walked into his secret room and took out a box.

"Calcined elixir!"

Han Li blew lightly in his mouth, the forbidden talisman on the box had been removed, took out the pill and looked at it carefully, confirmed that it was correct, and swallowed it.

Then, as a month passed, Han Li swallowed the second Refining Elixir as well.

Two months had passed before Han Li woke up from a burst of refreshment.

After looking at it for a while, although there was no obvious change, the strength of the physical body was still refined, and the flowing essence and blood in the veins were gradually thickening.

"It's time!"

Han Li casually pulled out a small jade ring, and his divine thoughts instantly attached to it, and the Xuan Jin Immortal Recipe moved slowly in his mouth, and he didn't stop in his hands, and hurriedly put out some magic weapons that had already been prepared, and forbade them.

Han Li began to follow this cultivation path of the Xuan Jin Immortal Technique, condensing his mana true element.

With the drive of the magic weapon, in the secret room that Han Li was in, a small dragon scroll formed by the immortal aura slowly appeared, and some of the nearby immortal aura was also swept in.

At this time, if someone were to observe Han Li's specific situation, they would find that a thin layer of colorless aura gradually condensed on the surface of his body, slowly rising from the bottom to the top, until the top of the skull turned into the Heavenly Spirit Cover and was wrapped into the Heavenly Spirit Cover, and so on and so on.

If you can find it carefully, this thin layer of halo actually expands automatically every few weeks, although it is very weak, but it seems to be a period of replacement.

And Han Li's expression was calm since he first started cultivating, and every time this aura widened by a point, Han Li's face couldn't help but tremble.

Three years had passed, and the aura that had been carried with him had expanded by one point, and Han Li's eyebrows twitched unconsciously, but his expression was still indifferent.

In the past three years, every time this aura expanded by one point, Han Lijun's face twitched, and he had a solemn expression.

Another three years had passed, and the aura had completely enveloped Han Li like a cocoon, and every time Han Li's aura expanded, he gritted his teeth, and his expression showed a little pain.
