Han Li pressed the jade slip containing the Four Seasons of Water Evolution exercises to his forehead, his eyes closed, and his body remained motionless, as if an old monk had settled down.

At first, his brows furrowed slightly, as if he was a little puzzled, but soon he stretched out again, he should have figured out something, but it didn't take long for his brows to frown again, then stretch again, and then repeat.

As time passed, Han Li's brows furrowed deeper and deeper, and he had not been able to stretch, as if he had been completely stumped by some difficulty, and sweat gradually seeped out from the corners of his forehead.

This time I checked, it turned out to be three days and three nights.

By the time Han Li's eyes opened, his back was already soaked with sweat, and his eyes were bloodshot, as if he had consumed a great deal of mental energy.

"How can this be......" he muttered as he removed the blue jade slip from his forehead.

In this "Four Seasons of Water Evolution", a total of seven volumes are recorded.

At the beginning of his cultivation, he also needs to condense a magic weapon like the Truth Wheel, called the "Time Purification Bottle", which can condense the water droplets of time by absorbing the essence of heaven, earth, sun and moon.

When the exercises are cultivated to the fourth volume, they will be able to begin to refine the collected droplets of time, from which they will condense the silk of time with the power of the law of time.

Han Li was actually no stranger to this kind of silk of time, as early as when he was in the spirit realm, he had seen it in the Shura Spider, known as the Nine Heavenly Treasures, which were rare things that could only be born in the so-called river of time containing the laws of time, which could prolong the lifespan of mortals or low-level monks, and could also delay the arrival of the heavenly tribulation of high-level monks.

Judging from the description of the exercises, the silk of time refined through the "Four Seasons of Water Evolution" contains the power of the law of time more refined, so the effect is more obvious, and it can even help the true immortal to delay the arrival of the three decays.

It's just that the condensation of the time purification bottle, like the condensation of the Truth Treasure Wheel, not only requires objects that contain the law of time, but also requires many other rare treasures, which is a big problem in front of the majority of monks.

This exercise is not like the Mantra Wheel Sutra, which condenses the immortal essence and improves the cultivation with the improvement of the exercise, but focuses more on how to improve the speed of condensing the water droplets of time.

It is said that when the water droplets accumulate into a river, there will be more indescribable magical powers that can be used, but the condensation speed is extremely slow, just take the initial cultivation, the condensation of each drop of water droplets is actually a hundred years, if you want to accumulate water into a river, I don't know how much time it will take, I am afraid that even the Golden Immortal will not be able to do it at all.

After such a comparison, Han Li found that the Four Seasons of Water Evolution seemed to be slightly weaker than the Truth Wheel Sutra, but it also had its own uniqueness.

Now he has only browsed it a few times, and he has not cultivated it all the way like the "Truth Wheel Sutra", so his understanding is naturally limited.

After Han Li took a deep breath, he temporarily suppressed the doubts in his heart, opened the Illusory Treasure Book again, and slowly flipped through it.

There was silence in the inner room, except for the rustling of books.

In this moment, it was more than a day.

Han Li slowly closed the waxy book and rubbed his brows, which were a little painful, but the corners of his mouth slowly rose, revealing a smile.

This "Illusory Treasure Book" is more peculiar than the previous two time exercises, although it claims to be a time exercise, but in fact, it is more like a refining treasure book.

The reason why Han Li felt this way was because after cultivating this technique to a certain level, he would be able to decompose some things that contained the power of the law of time, and extract something called "Phantom Chensha" from it.

And this kind of Phantom Sand, as long as it is refined in a special way, can create a closed small space with sand grains, and call it the Phantom Sand Realm, such as a Phantom Sandbox, Phantom Sand Bottle, and so on.

And in the interior of these sandboxes or sandbottles, the speed of time changes.

"If the number of Phantom Chensha is large enough, will it ......" A thought suddenly appeared in Han Li's heart, and he couldn't help but raise his eyebrows upward.

After a while, his expression quickly returned to normal, and he laughed at himself, "Not to mention whether you can really do it, it's just that where are so many Illusory Sand to get the things of the law of time...... How can it be so good?"

After finishing speaking, he wandered his gaze again, looking back and forth at the two jade slips and the ancient book, revealing a deep groan.

These three exercises are the same as the power of the law of time, but they seem to have different emphases, except for the Truth Wheel Sutra, which can be cultivated as a practice, those two exercises are related to the treasure of the power of the law of time.

In addition, after comparing and figuring out the three exercises together, Han Li always faintly felt that there seemed to be some kind of connection between the three.

Of course, all three were related to the law of time after all, and it was understandable that there were some similarities, but as Han Li studied deeply, he found that things didn't seem to be so simple, but when he wanted to confirm each other, he felt that some things were not right.

......

Time flies, and more than ten days have passed.

In the inner chamber of the cave, Han Li stood with a long body, holding an ancient book and a jade slip in his hand, with a wry smile on his face.

After days of hard thinking, I was still at a loss.

"That's it, if you continue to drill the horns like this, I am afraid that if you form a knot in your heart, it will hinder your future cultivation. After a sigh, he turned his wrist and put away the ancient book and jade slip.

The Law of Time was known as the meaning of the Three Supreme Laws of the Immortal Realm, and its related exercises were different from ordinary exercises after all, and Han Li did not plan to rashly cultivate the other two time exercises without figuring out the relationship.

Of course, in the end, the situation is not stable now, and there is not so much time.

Thinking so in his heart, he sat down cross-legged again, flipped his wrist, took out a white jade porcelain bottle, poured out a transparent jade-like elixir from it, and swallowed it.

This pill is called Xueluo Pill, it is one of the golden immortal-level pills obtained from Xiao Jinhan before, it has the effect of consolidating the foundation and promoting cultivation, and it is suitable for him to take it now.

After a moment, Han Li's expression returned to calm, and after sitting down cross-legged, he began to close his eyes and breathe again.

After his mind was calm, he put the only remaining snow-white jade slip engraved with golden lines towards his eyebrows.

What is recorded on this jade slip is the fifth exercise of the "Truth Wheel Sutra".

I saw layers of golden ripples rippling from the jade slip, turning into a soft light that enveloped Han Li.

Compared to the hardship of the first practice of the fourth exercise, this fifth exercise was not so difficult to start, and after Han Li had memorized all the mantras, he put away the jade slip.

I saw that his hands were folded left and right in front of him, and he pinched out a magic trick, and there was immediately a golden light rippling behind him, and the Treasure Wheel of Mantra slowly came out of it, hanging in the air.

Because of the barrier of the forbidden magic circle, the fluctuations of the Truth Word Treasure Wheel did not leak in the slightest, but the golden boy and Xiao Bai in the outer room still noticed a trace of abnormality because of their unique connection with Han Li, and turned to look inside.

I saw that on the Truth Treasure Wheel, a cluster of Dao patterns of light was magnificent, like a small golden sun, shining brightly.

Time passed quickly, and more than three months passed quickly.

During this period, the Dark Star Canyon became more and more lively, and in addition to the other largest tribes, nearly half of the other small and medium-sized tribes had migrated to the Youchen Clan.

The Youchen Clan was lively and busy, Nuo Yifan had been here twice in the first month, and was told that Han Li had never been to this cliff since he had been in retreat, and everyone seemed to have forgotten that there was still a human race living here.

On this day, in the mountain cliff cave, a little girl in red and a white Pixiu all opened their curious eyes, standing in front of the forbidden light curtain in the inner and outer rooms of the cave, looking inside.

Just half an hour ago, after Han Li had taken a round fruit with dense golden dots on its surface, the Truth Wheel behind him became brighter and brighter.

On the outside of his thigh, a small golden vortex appeared, and layers of dense golden light were constantly gathering around him, surging towards the whirlpool, which was his sixty-first immortal aperture!

And with the generation of this immortal aperture, the time path pattern on the Truth Treasure Wheel also had two more balls at the same time.

A moment later, when all the surrounding fluctuations gradually became smaller, Han Li also slowly opened his eyes, and there was not much joy in his eyes, but rather a little sadness.

"With the help of a fruit that contains the power of the law of time, it is difficult to open up an immortal aperture, and when you want to cultivate to the Taiyi realm, you don't know how many resources it will take......" he couldn't help but smile bitterly.

However, as soon as his words fell, a blue light lit up in his chest, and the dark green vial suddenly flew up on its own.

Han Li raised his eyebrows and hurriedly looked at the Truth Treasure Wheel, and was pleasantly surprised to find that there were eleven golden silk threads entwined on it, flashing with crystal light, which was the Silk of Time.

The fruit that he had obtained from the public for a long time and still didn't know what it was, unknowingly, made him have an extra time crystal, which was really unexpected.

Just looking at the posture of the Palm Heaven Bottle in front of him, it seems that he is about to cross again.

Sure enough, with a "boom" sound, a thick green light gushed out from the dark green vial, which had already expanded like a grinding disc, and happened to hit the prohibition at the division of the inner and outer rooms, directly tearing the void and condensing the strange crystal wall.

Jin Tong and Xiaobai's vision was blocked by the crystal wall and the prohibition, and they could neither see the scene inside, nor could they detect the changes inside, so they had to return to the stone table a little boringly.

Han Li looked at the green vortex that gradually appeared in the crystal wall, and his eyes slowly closed.

Immediately after, a huge and peculiar suction force suddenly appeared, enveloping his whole person, and the power of his divine soul suddenly came out of his body like a wild horse that had escaped, and disappeared into the crystal wall vortex in a flash.
