"That's right. This person is now called Ryugo. Jiao San didn't hesitate, and nodded directly.

"Oh, how much time did you give this Ryugo?" asked the Scarface man, frowning slightly.

"Fifteen years. Jiao San replied calmly.

"With all due respect, even Master Ximen probably can't guarantee that the Xuyuan Pill will be successfully refined within fifteen years. Scarface said meaningfully.

"As the saying goes, distant water can't save near fire, and now Master Ximen is not in this immortal realm, and the time left for us is less than twenty years. Do we have any other choice?" Jiao San asked rhetorically.

"After all, this matter is very important, this person has just joined the main hall, are you really relieved?" Scarface suffocated, and then asked.

"So I didn't let him go. Jiao San said slowly.

"What if this person can't complete the task by the deadline?" Scarface asked, still worried.

"There have been enough things that have happened in the past few years, and there are not many sons of reincarnation in the Northern Cold Immortal Domain, and the battle of Candle Dragon Dao has greatly damaged our vitality. If this can be done, then all the effort made before will be worth it. Therefore, in this matter, only success is allowed, and failure is not allowed. Jiao San was silent for a long time and said very firmly.

"It seems that you have a lot of confidence in this person, could it be that you have already sent someone to secretly observe?" Scarface glanced at Jiao San and said.

"I'm new to this person, and I didn't know him before. Jiao San shook his head.

"Then you ......," Scarface said with a frown.

"Don't worry, I'll be responsible for all the consequences of this matter. To get back to the point, you just need to do your part and find out about the affairs of Red Moon Island. Jiao San interrupted the other party's words with a speech, and commanded in a sharp manner.

"Well, since you're so sure, I'm not going to say anything. The Scarface man glanced at Jiao San and said.

"You should have asked, you also asked, this place is not suitable for a long time, you better go back first. Don't see each other again all these years. Jiao San said in a somewhat cold tone.

"Okay, then take your leave. Scarface said, and a black light suddenly appeared on his body, like a shadow, spreading towards the surroundings.

As soon as the man's body moved, his body melted into the black light and disappeared.

Jiao San sat silently for a moment, then stood up and looked in the direction of Han Lidong's mansion.

......

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

Inside the secluded cave mansion, Han Li sat cross-legged, his whole person motionless, like a stone statue.

His entire head was now enveloped in a soft, bright crystalline light, making his face look a little hazy.

The crystal light is soft like water, flowing gently, and it looks a little pleasing to the eye.

At this moment, Han Li's eyelids moved slightly, and then he opened his eyes.

The crystal light surrounding its head flashed, and it suddenly disappeared into its eyebrows like a long whale sucking water.

After Han Li let out a long breath, a hint of joy flashed in his eyes.

In the past ten years, he has been practicing penance almost day and night, and this fourth-level alchemy has finally been slightly completed.

At this moment, the power of his divine consciousness has not improved much, but the hidden dangers in it should have been controlled, and the operation of the huge divine consciousness power in his mind has become smooth and natural again, without a trace of disorder.

But the next moment, there was a flash of joy in his eyes, replaced by some doubt.

According to the classics, this fourth-layer alchemy technique is far more profound than the first three layers, and the difficulty of cultivation is more than ten times that of the first three layers.

Therefore, he didn't plan to cultivate the fourth-layer alchemy technique to a small level in one go, he just wanted to calm down the hidden dangers in his divine consciousness and stop, after all, he still had the task of alchemy, and he didn't have enough time.

But to his surprise, the cultivation of this fourth-layer secret technique was as natural as it was, and there were almost no bottlenecks, so that in just ten years, it had reached a small success.

The thought in his heart was spinning rapidly, and he couldn't figure out why.

Now it seems that it can only be attributed to talent for the time being, perhaps because of his current physique, which is very suitable for cultivating this kind of secret art.

This was the case with the cultivation of the Great Yan Decision back then, and the same is true of this alchemy now.

No matter what the reason, the matter must be stopped now, and now there are only seven or eight years left, and the alchemy must be started as soon as possible.

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

Without saying a word, he released his divine sense to probe into it, and once again confirmed the thirty Dao Dan materials inside according to the Dan Fang, to ensure that there were no mistakes or omissions.

Just as Han Li was about to take out the materials and start trying the alchemy, his complexion changed slightly, and a soft sigh came out of his mouth.

With a movement of his fingers, a document appeared in front of him.

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

The whole body of this object was pitch black and shiny, emitting a layer of ghostly light, as if it could absorb all the light around it, and at the same time, a strong wave of law power emanated from the black crystal.

This black crystal is the main material of this Danfang called Xuyuan Dan given by Jiaosan, which is called Black Marrow Crystal.

Han Li reached out and picked up this black marrow crystal, and suddenly felt a tingling pain in his five fingers.

The strange power of the law emitted by the black marrow crystal had a strong corrosive force, and it was also a little unbearable when it came into direct contact with his Xuan Immortal body.

While thinking about it, a layer of blue light immediately appeared on the surface of his palm, which immediately isolated the corrosion of the black crystal.

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

The two things looked very similar, and the nature of the aura emitted was almost identical, but the aura emitted by this black pith crystal was many times stronger than that of Mo Yujing.

It seems that there should be some connection between Mo Yujing and Black Marrow Crystal, Jiao San once asked himself about Mo Yujing's whereabouts, could it be for these Black Marrow Crystals?

But in the Black Wind Sea, Mo Yujing is already extremely rare, where did he get so many black marrow crystals?

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

Regardless of why, his task at the moment was just to refine this Void Yuan Pill.

After he put Mo Yujing away, he took out the jade slip that recorded the Danfang and pasted it on his forehead.

Half a month has passed in the blink of an eye.

Han Li was still sitting cross-legged with his eyes closed at the moment, and around him, there were stacks of spiritual materials, each of which looked like the same, and when counted, there were as many as thirty piles.

Suddenly, as soon as his eyes opened, his sleeve robe shook without saying a word, and a silver light flew out and landed on the open space in front of him.

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

After a while, the inside of the Dan furnace became hot.

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

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

A crystal filament flew out of its fingertips, and in a flash it was wrapped around the round wheel, exuding a strong aura of the law of time, which was the time crystal filament.

The filaments looked a little brighter at the moment, but they were still far from their heyday.

Of the three hundred and sixty regiments of time dao patterns on the treasure wheel, only eighteen regiments were in a bright state at this moment, and the rest of the time dao patterns were all dim.

Seeing this, Han Li's heart moved slightly.

It seems that the time crystal is closely related to the mantra treasure wheel, and I am afraid that only when all the time dao patterns on the treasure wheel are fully recovered, this time crystal will also be restored to its original state.

He thought so in his heart, and urged the law to be decided in his hand.

Airplanes!

A golden ripple poured out from the Truth Treasure Wheel and spread towards the surroundings, enveloping the Dan Furnace, and everything in the Dan Furnace suddenly slowed down.

It's just that at this moment, there are only eighteen regiments of time patterns on the treasure wheel, and the effect of delaying time is limited.

But for him, it should be enough.

Just as Han Li was groping for alchemy, on the Black Wind Island, which was thousands of miles away, it was the day when the once-in-a-century teleportation array was opened.

The shops on the streets of Black Wind City look much more depressed than before at this moment.

Except for some bustling streets in the center of the city, other places seem a little deserted, there are not many pedestrians on the streets, and many shops are also crowded in front of them, there are no customers, and they look weak.

Over the years, I don't know what happened in the Black Wind Sea, and there have been frequent changes and drastic changes, or shocking tsunamis, or volcanic eruptions, or violent storms.

Many islands were destroyed by these natural disasters, causing countless casualties, and for a while, the entire Black Wind Sea was panicked, and there were even rumors that the Black Wind Sea was about to be destroyed.

Even Black Wind Island and Blue Feather Island, which had been fighting endlessly, seemed to be shocked by these natural disasters, and the battle subsided.

Although Black Wind Island was not affected by these natural disasters, the business in Black Wind City was also greatly affected, and the teleportation array, which had always attracted great attention, was opened, and not many people came to watch.

The teleportation array inside the tower was buzzing at the moment, emitting a dazzling light.

Two figures stood near the teleportation array, and one of them was a middle-aged man in a brocade robe wearing a feather crown, it was none other than Lu Jun, the lord of Black Wind Island.

He looked at the teleportation array, and his expression was faintly excited.

The other person was dressed in a white robe, and in terms of sword eyebrows, it was the man surnamed Feng who led a group of people to Black Wind Island back then.

This person's gaze was also looking at the teleportation array, but it seemed much calmer.

Suddenly, the entire teleportation array shone brightly, and a pillar of sky-high light emanated from it, causing the entire teleportation tower to tremble slightly.

The pillar of light flickered for a few breaths, and then quickly dissipated.

Some figures appeared in the teleportation array, the number was not large, only more than twenty people, but they were faintly divided into two factions with equal numbers, maintaining a considerable distance from each other.
