"That's right. This person is now called Long Wu." Jiao San nodded directly without hesitation.

"Oh, how much time did you give this Long Wu?" The scarred man frowned slightly and asked again.

"Fifteen years," Jiao San replied calmly.

"Forgive me for speaking frankly, but even Master Ximen probably cannot guarantee the successful refinement of Void Essence Pills within fifteen years," the scarred man said meaningfully.

"The proverb says that distant water cannot quench immediate thirst. Master Ximen is not in this Immortal Territory now, and we have less than twenty years left. Do we have any other choice?" Jiao San asked rhetorically.

"This matter is, after all, of great importance. This person has just joined the palace. Are you really at ease?" the scarred man asked after a pause.

"That's why I haven't let him leave," Jiao San said slowly.

"What if this person cannot complete the task before the deadline?" the scarred man asked worriedly.

"Enough has happened in recent years. There are not many Children of Reincarnation in the Northern Cold Immortal Territory to begin with, and the Battle of the Candle Dragon Dao has greatly depleted our vitality. If this matter can be accomplished, then everything we have paid before will be worth it. Therefore, this matter is only allowed to succeed and not allowed to fail," Jiao San said after a long silence, with unusual determination.

"It seems you have great confidence in this person. Could it be that you have sent someone to observe him secretly long ago?" The scarred man glanced at Jiao San and said.

"I only just came into contact with this person, and I didn't know him before," Jiao San shook his head.

"Then you..." The scarred man frowned tightly.

"Don't worry, I will be responsible for all the consequences of this matter. Getting back to the main topic, you only need to do your job and find out about Hongyue Island," Jiao San interrupted the other party and ordered, changing the subject.

"Alright! Since you are so confident, then I won't say anything else," the scarred man said, glancing at Jiao San.

"You've asked what you needed to ask. It's not appropriate to stay for long. You should go back first. Let's not meet again in these years," Jiao San said in a somewhat cold tone.

"Alright, then I'll take my leave," the scarred man said, and a black light suddenly appeared on his body, spreading around like a shadow.

With a movement of his figure, the man merged into the black light and disappeared.

Jiao San sat quietly for a moment, then stood up and looked in the direction of Han Li's cave.

...

Time passed, and ten years went by in the blink of an eye.

Inside a quiet cave, Han Li sat cross-legged, motionless, like a statue.

His entire head was now shrouded in a soft and bright crystal light, making his face appear somewhat hazy.

The crystal light was as gentle as water, flowing gently, giving people a pleasing and delightful feeling.

Just at this moment, Han Li's eyelids twitched slightly, and then he opened his eyes.

The crystal light surrounding his head flashed, and then, like a whale absorbing water, it all disappeared into his forehead.

Han Li breathed out a long sigh, a hint of joy flashing in his eyes.

After ten years of almost non-stop hard work, this fourth level of Divine Refinement Technique was finally somewhat accomplished.

At this moment, his divine consciousness power had not increased much, but the hidden dangers within should have been brought under control. The operation of the vast divine consciousness power in his mind had once again become smooth and natural, without any disorder.

But in the next moment, the joy in his eyes faded, replaced by a hint of doubt.

According to the records in the classics, this fourth level of Divine Refinement Technique is far more profound and subtle than the first three levels, and the difficulty of cultivation is more than ten times that of the first three levels. Even if one only wanted to achieve success, it would take at least several decades, or even hundreds of years.

Therefore, he had not intended to cultivate the fourth level of Divine Refinement Technique to completion in one go. He only wanted to calm the hidden dangers in his divine consciousness and then stop, after all, he still had the task of refining pills, and time was not abundant.

But to his surprise, the cultivation of this fourth level secret technique was like a natural process, and he encountered almost no bottlenecks, so that in just ten years, he had reached completion.

His mind raced, considering the reasons, but he could not figure it out.

Now it seems that he can only temporarily attribute it to talent. Perhaps his current physique is very suitable for cultivating this type of secret technique.

It was the same when he cultivated the Great衍Decision in the past, and it is the same with this Divine Refinement Technique now.

No matter what the reason, he must stop now. There are only seven or eight years left, and the pill refining matter must be started as soon as possible.

With this thought in mind, Han Li flipped his hand and took out a storage ring, which was the one Jiao San had given him earlier.

Without saying a word, he released his divine consciousness and probed into it, once again confirming the thirty sets of Dao pill materials inside according to the pill formula, to ensure that there were no mistakes or omissions.

Just as Han Li was about to take out the materials and start trying to refine pills, his expression changed slightly, and he let out a soft exclamation.

With a flick of his finger, a set of materials appeared in front of him.

Han Li didn't look at the other materials, but his gaze fell on a fist-sized black crystal.

This object was jet black and shiny, emitting a faint light, as if it could absorb all the surrounding light. At the same time, a strong wave of the power of laws emanated from the black crystal.

This black crystal was the main material of the pill formula that Jiao San gave him, called Void Essence Pill, named Black Marrow Crystal.

Han Li reached out and picked up the Black Marrow Crystal, and immediately felt a stinging pain in his fingers.

The strange power of laws emitted by the Black Marrow Crystal has a strong corrosive power. Even with his Profound Immortal body, direct contact is somewhat unbearable.

As he pondered, a spiritual light flashed on the surface of his palm, and a layer of green light immediately appeared, isolating the corrosion of the black crystal.

At the same time, he moved his other hand, and a black stone block appeared out of thin air in his palm, which was the Moyu Crystal.

The two objects looked very similar, and the nature of the aura they emitted was almost exactly the same, except that the aura emitted by the Black Marrow Crystal was many times stronger than that of the Moyu Crystal.

It seems that there should be some connection between Moyu Crystal and Black Marrow Crystal. Jiao San once inquired about the whereabouts of Moyu Crystal, could it be for these Black Marrow Crystals?

But in the Black Wind Sea, Moyu Crystals are already extremely rare. Where did he get so many Black Marrow Crystals?

Han Li's mind fluctuated, and he quickly shook his head, no longer bothering to think about these things.

No matter why, his task at the moment is just to refine this Void Essence Pill.

After he put away the Moyu Crystal, he took out the jade slip recording the pill formula and put it on his forehead.

In the blink of an eye, half a month had passed.

Han Li was still maintaining the posture of sitting cross-legged with his eyes closed. Around him, there were piles of spiritual materials, each pile looking exactly the same. Upon closer inspection, there were as many as thirty piles.

Suddenly, he opened his eyes, and without saying a word, he flicked his sleeves, and a silver light flew out, landing on the open space in front of him. As the silver light flashed, a silver pill furnace appeared in front of him.

Then he opened his mouth and spat out, and a silver flame directly fell on the bottom of the furnace, burning fiercely.

Before long, the inside of the pill furnace became scorching hot.

Seeing this, Han Li nodded slightly, and then raised one hand, and a certain spiritual material from a pile of materials in front of him flew up and was directly put into the furnace.

At the same time, a dazzling golden light appeared on his body, condensing into a golden halo behind him.

A crystal thread flew out from his fingertips, flashing and wrapping around the halo, emitting a strong aura of the law of time. It was the Time Crystal Thread.

The crystal thread looked a little brighter at the moment, but it was far from its peak state.

Of the three hundred and sixty Time Dao Patterns on the treasure wheel, only eighteen were in a bright state at the moment, and the rest of the Time Dao Patterns were all dim and dull.

Seeing this scene, Han Li's heart moved slightly.

It seems that the Time Crystal Thread and the Mantra Treasure Wheel are closely related. Perhaps only when all the Time Dao Patterns on the Treasure Wheel are fully restored will the Time Crystal Thread be restored to its original state.

Thinking like this in his heart, he urged the magic formula in his hand.

Buzz!

A golden ripple涌ed out from the Mantra Treasure Wheel, spreading towards the surroundings, covering the furnace, and everything inside the pill furnace suddenly slowed down.

It's just that only eighteen Time Dao Patterns on the Treasure Wheel are bright at the moment, and the effect of delaying time is limited.

But for him, it should be enough.

Just as Han Li was exploring pill refining, on Black Wind Island, which was tens of thousands of miles away, it was time for the opening of the teleportation array once every hundred years.

The streets and shops in Black Wind City looked even more deserted than before.

Apart from some prosperous streets in the center of the city, other places seemed a bit desolate. Not many pedestrians could be seen on the streets, and many shops had few customers, looking lifeless.

In recent years, something unknown had happened in the Black Wind Sea, with frequent anomalies and constant changes, such as seaquakes, volcanic eruptions, or storms.

Many islands were destroyed by these disasters, causing countless casualties. For a time, the entire Black Wind Sea was in panic, and there were even rumors that the Black Wind Sea was about to be destroyed.

Even Black Wind Island and Qingyu Island, which had been fighting endlessly, seemed to be deterred by these disasters, and the fighting subsided.

Although Black Wind Island was not affected by these disasters, the business in Black Wind City was also greatly affected. The opening of the teleportation array, which had always attracted much attention, did not attract many people to watch.

The teleportation array in the tower was buzzing and operating at the moment, emitting a dazzling light.

Two figures stood near the teleportation array. One of them was a middle-aged man in a brocade robe with a feather crown, who was none other than Lu Jun, the island owner of Black Wind Island.

He looked at the teleportation array, with a hint of excitement in his expression.

The other person was dressed in a white robe, with sword-like eyebrows. It was the Feng-surnamed man who led a group of people to Black Wind Island in the past.

This person was also looking at the teleportation array, but he seemed much calmer.

Suddenly, the entire teleportation array shone brightly, emitting a pillar of light, causing the entire teleportation tower to tremble slightly.

The pillar of light continued to flicker for a few breaths, then quickly dissipated.

Some figures appeared in the teleportation array. The number of people was not large, only about twenty, but they were vaguely divided into two factions of roughly equal numbers, maintaining a certain distance from each other.
