Half an hour later, Han Li came to the center of the dark room again, laid out a futon, and sat down cross-legged.

He reached into his arms and took out the storage bag that the Dao Speaker had given him after entering the Immortal Mansion.

After opening it, he took out a snow-white jade slip inlaid with golden lines from inside, and his divine sense slowly sank into it, and he examined it carefully.

What is recorded in this jade slip is nothing else, but the fourth exercise of the "Truth Wheel Sutra".

Compared to the second and third level exercises, which were the Valley Secret Realm, the White Sparrow Guiding the Way, and the Broken Stone Tablet, this fourth level of exercise was really much easier to obtain, which made Han Li himself feel a little unreal.

However, he also figured out later that most of the remnants of the monument in the secret realm of the valley were the first triple exercise scrolls that the Candle Dragon Dao Master had obtained back then, and they were deliberately placed there to hide people's eyes and ears, making people mistakenly think that the Candle Dragon Dao only had these three folds.

As for the jade slip in his hand, it was the same as the first exercise he had obtained before, but it was just a copy.

The content of the fourth "Truth Wheel Sutra" was more lengthy and difficult to understand than the first three, and Han Li plunged into it and read it hard for more than a month before he finally read through the entire exercise.

On the basis of the cultivation of the first three exercises, he only roughly understood the cultivation mechanism of this heavy exercises, but there were still some key points in it, and he couldn't figure it out for a while.

However, there was a special feature that he found in it, but he was pleasantly surprised.

It turned out that starting from the fourth level of the Truth Wheel Sutra, because the cultivator had already accumulated a lot of the power of the law of time in his body, he was able to condense the silk of time through his perception during the cultivation process.

As for how much can be condensed, it depends on how much of the power of the law is stored in the cultivator's body, and the strength of his perception of the law of time.

For the next two months or so, Han Li was not in a hurry to start cultivating the Truth Wheel Sutra, but instead carefully reviewed the first threefold exercises, connecting them with the fourth-fold exercises, mirroring each other and comprehending each other.

However, this process takes a lot of time, but it has little effect, and the perception of some important points is still stagnant.

Han Li was not surprised by this, and he was fully prepared. Now that you still can't leave, it's better to calm down and cultivate first, while improving your cultivation, and then comprehending the exercises again, maybe there will be unexpected gains.

On this day, after meditating in the dark room for half a day, he took an elixir of intensive cultivation, and then began to cultivate the Truth Wheel Sutra.

A burst of golden light surged in front of him, and the Treasure Wheel of Truth spun leisurely and emerged.

Han Li raised his eyes and immediately raised his eyebrows, revealing a look of surprise.

I saw that above the treasure wheel, there was a time pattern lit up, flashing with translucent light.

Han Li's pupils shrank slightly, and a trace of doubt flashed in his heart.

He had been so busy contemplating the Mantra that he hadn't noticed it at all.

From the previous disappearance of all the Dao Patterns to the present, at most four months have passed, and it stands to reason that there should not be any Dao Patterns restored, is it because of the two more threads of the law of time?

The Time Crystal was so mysterious that Han Li still hadn't been able to figure out what it was for, but if it could speed up the recovery of the Time Dao Pattern, it would be great news.

Han Li couldn't figure it out for a while, so he cleaned up his mood and began to cultivate the Truth Wheel Sutra.

I saw the magic trick in his hand pinching, and a small chanting sound sounded in his mouth.

Bursts of golden light rippled from the Truth Wheel hanging in front of him, floating behind him and hovering above his head, beginning to shine brightly.

The golden light cast on it immediately filled the entire dark room.

......

Time flies, and more than 100 years have passed in a blink of an eye.

Inside the dark room, Han Li sat cross-legged and motionless, motionless as a stone statue, but a pale golden light appeared above and below his body.

After a long time, he slowly opened his eyes, and the faint golden light in his eyes flickered slightly, and then disappeared into the bottom of his eyes.

"Looking at this situation, I'm afraid that a thousand years may not be able to successfully open up an immortal aperture...... Could it be that you really want to cultivate that Xuansha Spiritual Skill?" his brows furrowed slightly, his expression was a little hesitant, and he muttered to himself.

After thinking for a moment, his heart suddenly moved, and he whispered "magic light".

The shadow in front of him twisted and swayed, writhing forward and elongated a few points.

A slight strange sound sounded in the dark room, and a black figure broke away from the shadow in front of Han Li and slowly stood up.

The figure was dressed in a black robe, his skin was as dark as ink, and his appearance was somewhat similar to Han Li's, with black hair draped behind him, and a faint black demonic aura around his body, but it was the demonic light.

After so many years of recuperation, it seems to have fully recovered, and the aura on its body is still better than before.

"Han Daoyou, you finally rang out. The corners of the magic light mouth hooked, revealing a wicked smile, and said slowly.

As soon as he said that, he suddenly sensed the aura emanating from Han Li's body, and his expression changed suddenly.

Han Li saw this change in his eyes, but he didn't show any performance, he just said indifferently:

"I've been through a lot of things over the years, but it's just not suitable for you to show up. Today, I happened to have an inquiry, and I hope that the Demon Light Daoist friends will advise. ”

"I didn't expect that after seeing it last time, Han Daoyou is now a golden immortal, and it seems that the vision of the magic light to choose the master is much better than before. If Han Daoyou has anything to ask, just say it. Magic Light said with a smile.

"How much do you know about the Gray Realm?" Han Li asked again.

"Gray Realm? This has always been a secret in the Immortal Realm, even Ma Liang, and he probably didn't participate much back then, so I don't know much, I only know that it is a boundless realm comparable to the Immortal Realm. Magic Light thought for a moment and said.

"What about evil qi, do you know something?" Han Li asked a little disappointed.

"When it comes to evil spirits, you monks should know better than I do. Whenever there is an act of killing, it will form a ferocious aura in the body, just like when our demons outside the world kill, they can absorb demonic qi. It's just that you don't manifest on a daily basis, unless some people kill too much, and the evil spirit turns into reality, and then they will manifest themselves. Magic Light explained.

"Then have you ever heard of any exercises in the Immortal Realm that can be used to improve one's cultivation through evil qi?" Han Li nodded thoughtfully and asked.

"As far as I know, this kind of exercise does exist, but generally no monk will take the initiative to cultivate, and it is said that it will affect the promotion of cultivation at a certain stage in the later stage, which is equivalent to invisibly adding a bottleneck to one's own cultivation, which is an act of asking for hardships. After a slight groan, the magic light said slowly.

When Han Li heard this, he didn't speak for a long time, and the magic light stood quietly aside, silently looking at him.

"I've worked hard this time, and when it's over, I'll talk to you again. Han Li glanced up at the Demon Light, and with a flick of his robe, the figure of the Demon Light blurred again, merging into his shadow.

"Tens of thousands of years, I can't afford to wait......"

After Han Li sighed, he pinched the strange magic technique with both hands, and a black light flashed around him, and the evil qi in the sky suddenly surged, covering the entire dark room.

As the chanting sound in his mouth gradually sounded, the evil qi that seemed to be chaotic and disorderly like a dark cloud surging suddenly stopped spreading to the periphery like a wild horse that had been reined in, and began to gradually shrink and gather.

Its color became heavier and heavier, and the smoke became more and more condensed, clinging towards Han Li's body.

After the evil qi solidified and then touched his skin, Han Li immediately felt a strange feeling, and his heart tightened, but he didn't stop there, but continued to lead these evil qi towards the tricks on his body.

I saw that these evil qi were like mana, gathering together and rushing towards a trick point under his ribs, and the trick that had not moved at all was suddenly attacked by the surging evil qi, and there were signs of collapse.

Seeing this, Han Li's heart moved, and he immediately closed his eyes and concentrated on cultivating.

I don't know how long it took, with a slight sound coming from Han Li's body, and then a small vortex appeared under his ribs, attracting the surrounding Heaven and Earth Yuan Qi to surge in, gurgling into his acupoint.

Dozens of breaths later, after all the golden light disappearance completely disappeared, an extra golden point of light appeared under Han Li's ribs.

This thirty-seventh immortal aperture has finally been penetrated!

Han Li's mind moved, and he probed towards the immortal aperture, only to see that in addition to condensing a large amount of immortal spirit power inside, there was also a wisp of black evil qi floating inside, which looked very faint and did not have much of an abnormality.

His heart was at ease, and with a slight wave of his palm, he beckoned the Truth Wheel to his side.

I saw that on the treasure wheel, in addition to a lot of time patterns that had been restored, there were two more regiments near the inner circle, a total of three hundred and sixty-two regiments.

Speaking of which, since he advanced to the Golden Immortal, he has not been able to take care of the matter of the Heavenly Bottle in these years, but he has not tried to continue to increase the Dao pattern through condensation crystals, so he can only make plans after leaving this place in the future.

Thinking like this, Han Li changed the magic technique in his hand, and silently urged the Truth Treasure Wheel to come, only to see the golden light rippling on it, releasing layers of golden ripples, everything was the same as before.

For the next two days, Han Li did not continue his cultivation, but carefully observed his condition, and after confirming that there were no obvious abnormal changes, he gradually relaxed his mind.

After taking the pill, he embarked on the journey of cultivation again.

......

I don't know how many years have passed, but it has been more than a thousand years.

On this day, since Han Li broke through the realm and became a golden immortal, it had been silent for a long time in the sky above the ruined city, suddenly a strong wind blew, dark clouds rolled, and the aura of heaven and earth was like a river tide, gathering towards a garden in the city.

In the dim sky, a spiritual energy vortex that was almost larger than the entire city was generated out of thin air, like a huge funnel that ran through heaven and earth, frantically pouring the vitality of heaven and earth into a large black hole in the garden.

The surging heaven and earth vitality instantly filled the entire Yongdao, like an endless river, pouring into a dark room in the depths of the underground palace.
