At this moment, many miles away from where Han Lidong's mansion was located, in a gray underground space, a gray-robed figure was sitting cross-legged with a crimson dragon's head mask on his face, and the word 'three' was written on it.

This person was none other than Jiao San, who had just made a deal with Han Li in the Impermanence Alliance.

After a moment's pause, it stood up and turned towards one of the several passages connected to the space.

After walking along a dark and dull underground tunnel for an unknown amount of time, it suddenly opened up in front of it, and a cave space of tens of zhang in size appeared in front of it, and at the end of the space, there was a gray stone gate blocked by a faint silver light curtain.

Jiao San pinched the trick with both hands without hesitation, and after reciting the words in his mouth, the silver light curtain trembled and opened from it.

That's when he pushed the door open.

At the door was a circular secret room about 20 zhang in size, empty except for a stone table and a stone chair.

On the stone chair, there was an old man in black wearing a black cloak, sipping a cup of spiritual tea.

The tea is blood-red, and the fragrance also exudes a strong bloody taste.

The old man had white eyebrows, a slightly crooked nose, and at first glance it looked like an eagle's hook, and a pair of pale golden eyes flashed with a cold light.

Jiao San glanced at the teacup in the white-eyed old man's hand, and a trace of disgust flashed in his eyes, but he immediately hid it again.

"How?" Seeing Jiao San appear, the white-eyed old man put down the teacup in his hand and asked.

This person's voice was a little hoarse, as if two pieces of metal were rubbing, but it sounded inexplicably terrifying.

"I got it near Red Moon Island. Jiao San sat down next to the white-eyed old man and spoke.

"Red Moon Island, didn't you go there to search once?" the white-eyed old man asked with a slight movement of his eyebrows, as if he was a little surprised.

"Although my actions on that day were disguised in the name of the Impermanence Alliance, it is difficult to ensure that they were not discovered in advance, and then deliberately tried to confuse us. Jiao San said coldly.

When the white-eyed old man heard this, he didn't speak, and gently tapped the table with his index finger with one hand, not knowing what he was thinking.

The old man didn't speak, and Jiao San didn't say anything either.

"What do you think of this incident? Is it the Ecstasy Array of Black Wind Island again?" After a while, the white-eyed old man asked.

"Probably not, if this matter is arranged by Black Wind Island, they should not arrange the place to be Red Moon Island again. Jiao San pondered for a moment and said.

"That's right, in this case, we will check the millions of miles around Hongyue Island again, and then act according to the original plan. The white-eyed old man said.

Jiaosan nodded.

The white-eyed old man stood up and walked quickly outside.

Seeing this figure disappear, Jiao San slowly stood up, took off the mask on his face, and walked outside.

His back changed for a while, glowing with a misty light, and then quickly became clear again, turning into a graceful figure, and the gray robe on his body also turned into a big red dress.

As you walk, it looks like a red flame fluttering in the wind.

Jiaosan's figure gradually drifted away, and soon blended into the gloom outside.

......

Time flies, and more than ten years have passed in the blink of an eye.

Inside the medicine garden, a stream of blue light emanated from Han Li's hand, and he carefully lifted out a foot-tall condensation grass and put it into a jade box.

This is the third condensation grass he has matured.

Han Li waved his hand to take back the jade box, turned around and walked out of the medicine garden, but instead of heading towards the secret room, he quickly left the cave mansion.

With a flash of blue light, his figure appeared in the middle of the island.

Han Li flipped over his hand and took out a few array disks of different colors, reciting words in his mouth, and pinching a little trick in his hand.

Several arrays suddenly appeared with various colored lights, and then turned into several rays of light and flew downward.

Bang!

The void around the cave suddenly flashed, and a thick yellow light curtain appeared, and countless yellow mist rolled on it, submerging the cave inside.

There was a loud muffled sound on the periphery of the island, and countless blue lights emerged from the sea, forming a blue hemispherical light curtain, and runes of different sizes flashed on the surface, enveloping the entire island inside.

Han Li had a word in his mouth, pinching a little, and several blue lights flew down, submerging into the light curtain.

A layer of water wave-like glow suddenly appeared on the blue light curtain, rippling.

The light curtain and the small island below suddenly disappeared without a trace, and only the blue sea was in sight.

Seeing this, Han Li nodded in satisfaction.

These prohibitions have been changed by him personally over the years, and now even if a late-stage True Immortal Realm cultivator arrives here, he may not be able to break it in a short period of time.

The outermost hidden prohibition was something he learned from a classic book in the Tao Yu storage artifact, which was even more mysterious, even if the early monks of the Golden Immortal used their divine sense to probe, they might not be able to discover this hidden island.

After doing this, Han Li turned around and turned into a cyan rainbow that flew into the distance.

A few days later, his form came to rest above a sea of raging seas.

It was also an inaccessible and remote place, similar to the temporary cave he had chosen.

It's just that its cave is located in the northwest of the Black Wind Sea, but here it is the southwest of the Black Wind Sea Area.

His consciousness spread, his body shook, flew in one direction, and after a few breaths, he landed on an island.

The island is not large, only less than 100 miles, and there is a gray mountain peak on it, and there are only gray rocks and mud everywhere, and there is little grass and trees, which looks very desolate.

After Han Li's gaze swept over, his fingers flicked.

One after another sword qi flew out, slashing halfway up the gray peak.

Mountains and rocks fell like rain, but after a while, a simple cave appeared.

Han Li flew into the cave mansion, and then with a wave of his sleeve, a series of radiant array flags flew out of it, and there were hundreds of them.

He said something in his mouth, and pointed at these flags.

Suddenly, with a roar, these array flags turned into rays of light of different colors and flew out, falling near the cave in a flash, and disappeared.

Several layers of forbidden light curtains emerged alternately, enveloping the cave, protecting it tightly, and under the continuous flash of light, they all merged into the void and disappeared.

After doing this, he sat down cross-legged, his sleeves shook, and a golden thunderbolt flashed out, turning into the figure of a crab man.

"Fellow Crab Daoist, although it is unlikely that outsiders will appear here, just in case, when I am in retreat, you still help me protect the Dharma first. If someone really breaks in, try your best to stop me first. Han Li said in a deep voice.

"Don't worry, unless there is an existence far beyond the Golden Immortal Realm, I will stop it. The crab man nodded, a layer of golden thunder light appeared on his body, and then the figure melted into the void and disappeared.

Seeing this, Han Li's expression on his face remained unchanged, but his heart was slightly shocked.

Because his divine sense suddenly couldn't sense the location of the crab man.

As soon as the thought in his heart turned, he secretly operated the alchemy technique, and a huge divine sense emanated, and only then did he vaguely perceive a faint trace of thunder and lightning fluctuations in the nearby void.

This thunder and lightning fluctuation was extremely weak, and if it weren't for his huge divine sense and the operation of alchemy, it would have been impossible to detect it.

Han Li was secretly surprised, and quickly shook his head, putting the matter aside for the time being.

The reason why he was so cautious, and he chose a temporary cave mansion and laid down a lot of prohibitions, was because he was going to refine the Dao Pill next.

According to the classics, when the Dao Dan is formed, there may be a rumored Dan Tribulation.

The so-called Dan Tribulation, according to the classics, is because each Dao Dan contains its corresponding purest law power, and some will have touched or even transcended the laws of heaven and earth in this realm, and are repelled by the power of the interface, so they will descend the Dan Tribulation to prevent the generation of Dao Dan.

And once the Dan Tribulation is formed, the movement is very great, and it is rumored that it is even above some Thunder Tribulations.

It's a remote place, but it's hard to guarantee that it won't attract some people.

His original cave mansion was nothing else, but it was quite troublesome to relocate the medicine garden, so he decided to come here for alchemy, after all, even if it was discovered here, there was a buffer time provided by the crab people, which was enough for him to leave calmly.

Han Li exhaled lightly, closed his eyes and sat still.

Time passed slowly, and after three days and three nights, he opened his eyes, and with a wave of his hand, a silver Dan furnace appeared.

Immediately, a silver light flew out of his hand and landed at the bottom of the Dan furnace, turning into a silver flame, and a silver villain loomed in the flame.

He then waved his arm, and all the same material emerged, almost filling the secret room.

At the same time, in his mind, he recalled the refining process of the Dao Dan, which he didn't know how many times, several times again.

After confirming that it was correct, he waved his hand and played a trick.

Rumble!

The silver flame at the bottom of the Dan furnace suddenly flourished, and the Dan furnace quickly became hot.

With a single movement of Han Li's hand, a white grain emerged, it was the time grain, and it flew into the Dan furnace.

The flame at the bottom of the furnace was scorching, and the surface of the white grains seemed to faintly begin to melt and become rounded.

The golden filaments within the grains brightened, emitting bursts of fluctuations in the power of the law of time.

He waved his hand over a jade box, and inside was a white spirit ginseng, which was made in heaven.

The other hand emitted a stream of blue light, enveloping the Heavenly Ginseng beneath it.

As the magic technique in Han Li's hand changed slightly, two large hands appeared in the blue light, holding the spirit ginseng and gently crushing it.

Although the Heavenly Ginseng was a rare spiritual object, it was not hard, and it was immediately flattened, gushing out a large area of white spiritual liquid.

With a slight movement of his fingers, a stream of blue light emerged, caught the spiritual liquid, and carefully put it into the Dan furnace.

The ichor immediately boiled, and some white smoke appeared inside.

Han Li's face was solemn, and he pinched the secret in his hand, controlling the flame at the bottom of the furnace.

In a few breaths, the white spiritual fluid turned into a small mass of white gelatinous substance, enveloping the time grains inside.

Seeing this, he groaned for a moment, and then summoned a small box of silver powder, which looked like some kind of bone powder had been ground from bones.

He raised one hand, and a stream of blue light emitted from his palm, enveloping the bone meal and throwing it into the Dan furnace.

At the same time, his other hand kept pinching the trick, controlling the flames under the furnace.

The silver bone meal quickly melted away as well, turning into a mass of silvery liquid that merged with the white gelatinous substance.

Without pausing too much, Han Li raised his hand and took the same material again and threw it into the Dan furnace.

In this way, time passed little by little, and most of the day passed in a blink of an eye.

Most of the materials in the secret room were put into the Dan furnace, and at this moment inside the furnace was a white pill the size of a dragon's eye, and the surface was still a little uneven.

Under the scorching flames at the bottom of the furnace, the white pill rotated gently, emitting bursts of white aura.
