Han Li carefully inspected the three spiritual herbs, then handed the Palm Heaven Bottle to the giant ape puppet, instructing it to water them on time, and left, returning to the secret chamber to sit cross-legged.

Now, there were basically no problems with the materials for refining the Myriad Wheel Pill. He only needed to wait a while longer, and he would soon be able to start refining it.

What worried him more now was the Dao Pill. The main and auxiliary materials had also been mostly collected, but he was still lacking the Celestial Creation Ginseng and Dew Condensation Grass, and he still had no clue where to find them.

Thinking this, Han Li flipped his hand and took out the Faceless Alliance mask, putting it on his face.

With a flash of green light, he skillfully browsed through the tasks he had posted before, but no one had responded to his request for these two spiritual materials.

After pondering for a moment, he waved his hand to cancel the previous tasks, and then reposted them.

However, this time the reward for the task was increased threefold.

He believed that with such a high reward, as long as he spent more time waiting, he would eventually be rewarded.

After doing this, he put away the mask and took out two more storage instruments, which he had obtained from the two Green Feather Island cultivators.

After scanning them with his spiritual sense, he couldn't help but shake his head.

The things found on the Black Wind Sea cultivators were indeed much worse than those found on cultivators from the outside world. The two of them had basically nothing that caught his eye, only some ordinary magical artifacts and some common materials.

Suddenly, his eyebrows twitched slightly, and he flipped his hand to take out a cyan token.

This object was found in the storage instrument of the bald man. It was the size of a palm, made of a kind of cyan spiritual jade. One side was engraved with a pattern of a phoenix-like cyan spiritual bird, and the other side had the word "Feather" written on it.

"It seems to be some kind of token from Green Feather Island..." he thought to himself.

This token didn't seem to have any information about the bald man, which was different from ordinary identity tokens, which was a bit strange.

Han Li examined the token a couple more times, then put it away. After all, he had no interest in the local forces of the Black Wind Sea like Green Feather Island, and naturally didn't want to waste time researching any tokens.

He closed his eyes, adjusted his breathing slightly, and began to comprehend the third level of the Mantra Wheel Sutra.

Speaking of which, although he had broken through to the late stage of True Immortal, he had never really started cultivating the third level of the Mantra Wheel Sutra, because this third level was far more obscure and difficult to understand than the previous two. He still hadn't completely comprehended it.

Now that the three main materials for refining the Myriad Wheel Pill needed time to mature, he could take this opportunity to comprehend it properly.

As the saying goes, cultivation knows no years. Time flew by, and in the blink of an eye, more than thirty years had passed.

The door of Han Li's cave mansion remained closed, and it had not been opened once in all these years. The door panels were covered in dust.

Of course, no one else had come here during this period.

At this moment, Han Li was standing somewhere in the medicine garden inside the cave mansion, carefully picking three golden spirit fruits from a golden spirit tree that was about ten feet tall, which were the Myriad Wheel Fruits.

He looked at the golden spirit fruits in his hand, nodded with satisfaction, and after putting them into his storage bracelet, he turned and walked out of the medicine garden, heading towards the alchemy room.

Passing by a fork in the road, Han Li paused and looked towards a secret room inside.

That was the place where Crab Daoren was in seclusion. About ten years ago, it suddenly asked Han Li to arrange a secret room for it, which Han Li naturally would not refuse.

However, it was still silent to this day, and he didn't know what it was doing.

Han Li shook his head. He felt more and more that this immortal puppet was unpredictable, and seemed to be hiding some unknown secrets.

However, as long as it didn't do anything detrimental to him, he naturally wouldn't bother to interfere. After all, there were too many things to do right now.

Thinking this, Han Li turned and entered the alchemy room. After activating the surrounding restrictions, he sat down cross-legged.

In these years, he had used most of the green liquid to ripen the three main spiritual materials: Myriad Wheel Fruit, Fallen Ying Flower, and Blood Crystal Lotus Root, except for supplying the Earth Fiend clone.

Today, he had finally ripened a batch of spiritual medicines, enough to prepare about thirty portions, and he could start trying to refine the Myriad Wheel Pill.

Han Li closed his eyes and sat quietly for half a day. After completely calming his mind, he suddenly opened his eyes.

With a wave of his hand, he took out the silver alchemy furnace, and then with a flick of his sleeve, a silver light flashed, and the Silver Flame Child emerged, landing below the alchemy furnace.

The child sat cross-legged, and with a wave of its small hands, the silver flames on its body immediately shone brightly, then split apart, transforming into nine identical flames, evenly enveloping the bottom of the alchemy furnace.

Han Li waved his hand again, and portions of the materials needed to refine the Myriad Wheel Pill emerged, divided into thirty portions, neatly arranged on the side.

He had thought about the method of refining the Myriad Wheel Pill countless times in his mind over the years, and it was naturally already extremely familiar.

He opened his mouth and spat out a stream of green light, which entered the alchemy furnace, and the lid of the furnace immediately moved away on its own.

Han Li took out a Myriad Wheel Fruit, and with a flick of his finger, several streaks of green sword light emerged, slashing around the spiritual fruit in a chaotic manner, instantly turning it into a mass of golden fruit puree.

He had already taken out a golden fruit core and placed it aside.

He carefully put the golden fruit puree into the alchemy furnace. The silver flames flickered, and the alchemy furnace quickly became extremely hot. The Myriad Wheel Fruit puree slowly melted, turning into a mass of golden liquid.

Han Li then took another white gelatinous material and put it into the alchemy furnace...

The door of the alchemy room remained closed for a full three years.

On this day, the door of the alchemy room flashed with light and opened with a bang.

A figure flickered, and Han Li walked out of it, his eyes flashing with excitement, as if he was in a pretty good mood.

He raised one hand, and with a flip of his palm, a flash of golden light appeared in the palm of his hand, and a pill the size of a dragon's eye suddenly appeared.

At first glance, the pill was light golden in color, emitting a soft golden light, but upon closer inspection, it could be found that the layer of golden light on its surface was actually composed of circles of fine, silk-like light golden lines, which looked extremely mysterious.

It was the Myriad Wheel Pill.

Such a small pill had as many as ten thousand layers of these light golden lines on its surface, which was probably the origin of its name, Myriad Wheel Pill.

As a pill to improve cultivation in the late stage of True Immortal, not only did the materials for refining it cost him a lot of effort, but the complexity of the refining process was also the most complex of all the pills he had refined so far.

Even though he was already quite accomplished in the art of alchemy and possessed the True Words Treasure Wheel that could delay time by a thousand times, in the first year, only half a furnace, or five pills, were successfully refined out of the full ten portions of materials.

But these failures allowed him to summarize a lot of experience, so that the success rate of refining increased continuously, and finally, in three years, thirty portions of materials were successfully refined into five and a half furnaces, a total of fifty-five pills.

In fact, let alone thirty portions of materials for refining the Myriad Wheel Pill, even ten portions would be almost impossible for ordinary alchemists to collect in a short period of time, and a success rate of more than 20% did not seem high, but if Ping Yaozi were to be resurrected and learn of this, he would probably be shocked to drop his jaw.

It should be known that even a single Myriad Wheel Pill, if taken to the outside world, would definitely cause Xiong Shan and the like to fight to the death for it.

Even if a late-stage True Immortal cultivator like Xiong Shan, who was quite wealthy, obtained a Myriad Wheel Pill, he would probably be reluctant to swallow it immediately, but would wait until the critical moment of opening up the immortal apertures before taking it.

After all, there were probably only a handful of pills that could improve the cultivation of the late stage of True Immortal even in the entire Northern Cold Immortal Territory, and even a large force like the Candle Dragon Dao might not have many, otherwise Golden Immortal cultivators would not be so rare.

But Han Li did not have such worries. As time went on, he could refine more, which could completely satisfy his continuous swallowing in the future cultivation process.

Han Li was in a very good mood at the moment, but it was not because the number of Myriad Wheel Pills he refined was large. More importantly, he found that after these three years, his alchemy skills had also improved by leaps and bounds, vaguely reaching a bottleneck.

He had a feeling that as long as he worked hard to cross this bottleneck, his alchemy skills would enter another realm.

Han Li took a deep breath, put away the pill in his hand, and with a change in his expression, he stepped out.

Not long after, he came to the medicine garden again, wandered around casually, and finally stopped at the place where the mother bean was planted.

Under his instructions, the giant ape puppet would drip green liquid into it every once in a while.

Now, so many years had passed, but the mother bean still showed no signs of germination.

However, with his previous experience, he was not in a hurry, and turned to a white spiritual pool.

The pool was about seven or eight zhang in size, and the surface was shrouded in a faint white mist.

In the pool, several blood-red lotus flowers floated on the water, and faint traces of blood-colored mist could be seen floating in the stamens, and a rich and extremely sweet smell wafted in the air.

One of the lotus flowers was particularly large, as big as a washbasin, and had a kind of feeling of being a crane among chickens. The other few were much smaller.

Han Li's eyes looked at the bottom of the blood-colored lotus flower. In the black mud under the spiritual pool, there was a huge lotus root as thick as a bucket, about ten feet long, emitting a strong blood light on its surface, and it was extremely crystal clear.

Several smaller sub-roots grew on the large root, but no matter the thickness or the color, they were far inferior to the large root.

A place on the large root suddenly showed a gray and dark color, as if it had been stained with ink. It was the size of a fist, and the color was very deep, which was very conspicuous.

This large lotus root was the Blood Crystal Lotus Root that he had photographed back then, to be used as a mother root to continue to reproduce, in order to provide the main material for refining the Myriad Wheel Pill.

After these years of continuous infusion of green liquid, this lotus root had at least 200,000 to 300,000 years of medicinal age.

The higher the age of the main material, the more or less it would naturally have some impact on the pill formation rate and efficacy of the Myriad Wheel Pill in the future.

However, Han Li's eyes turned to the gray area on the surface of the blood lotus root.

The symbiotic pattern had also undergone some changes in these years, not only reflected in the enlargement of the appearance and the deepening of the color, but also vaguely some lines appeared in it, shaped like the veins of a leaf.

Moreover, although it was extremely weak, he could still feel the traces of the power of law emanating from it.

It was not the law of time, but another unknown power of law.

Seeing this situation, Han Li's heart moved.

In the beginning, there was absolutely no fluctuation of the power of law in this symbiotic pattern. The current change should be caused by the influence of the green liquid over the years.

Now, he couldn't help but feel a trace of interest in what kind of changes this symbiotic pattern would produce in the future.
