After Wang Yu put away the golden ball transformed from the Crab Taoist, a thoughtful expression appeared on his face.

He carefully scrutinized all the information he had gathered so far, but still couldn't find any clues connecting him to the person behind the scenes.

After a long while, he exhaled lightly and shook his head.

Regardless of who that person was, since he was able to force himself into such a predicament at the time, he probably couldn't defeat him with his current abilities. For now, it was best not to meet him.

Since Fang Pan was able to find him before, this more powerful mastermind probably wouldn't let him go either. He just didn't know if this person was aware of his return to the Immortal World.

In any case, he must strengthen his strength as much as possible so that he wouldn't be at a disadvantage in any unexpected events that might occur.

In the meantime, he still had one thing to deal with.

As Wang Yu thought of this, he flipped his hand and took out a black array disc, which was the Star Shift Sub-Mother Disc.

Now that he was in the Zhulong Dao, which was billions of miles away from the Black Wind Sea, the connection with the array disc over there was minimal, let alone using it to teleport Heavy Water.

As a result, not only would the cultivation of the Earthly Fiend Avatar be affected, but the supply of Heavy Water, which could be used to refine the Heavy Water Pattern Thunder weapon, would also be cut off.

Both of these were things he valued greatly, and he couldn't let them be cut off.

Since setting foot on the Ancient Cloud Continent, this problem had been bothering him. He had considered it on the way to the Zhulong Dao, and now he finally had some free time.

Wang Yu immediately changed his outer robe and took out the cyan mask, putting it on his face.

The Star Shift Sub-Mother Disc was purchased from the Ever-Changing Alliance. To solve this problem, he had to start with the Ever-Changing Alliance. Although such a long-distance, small-scale teleportation treasure was almost unimaginable in the Spirit World, it didn't seem so mysterious in this Immortal World.

The reason for this should be related to the power of laws. Such treasures would more or less borrow some spatial laws, or contain spiritual materials with spatial power.

As a soft cyan light lit up from the mask, a cyan light curtain emerged, with countless large and small characters and patterns condensing on the surface.

Wang Yu went directly to the barter area and quickly searched on it.

Before long, his eyes lit up, and he pointed out with his finger in the void, then waited.

After waiting for a full half an hour, a cyan light finally shot out from the light curtain, and the cyan light landed, condensing into a phantom of a man wearing a cyan fierce tiger mask, tall and wearing a cyan feather robe.

"Fellow Daoist is... I remember, Fellow Daoist once bought a set of Star Shift Sub-Mother Discs from me. How is it? Is that set of array discs working well for Fellow Daoist?" The tiger-masked man sized up Wang Yu and smiled somewhat knowingly.

"It's okay!" Wang Yu replied noncommittally.

"Fellow Daoist must have encountered some problems during use?" The tiger-masked man asked upon seeing this.

"The array disc's function is about the same as described, but Fellow Daoist didn't tell me back then that this disc has considerable limitations in terms of distance, did you?" Wang Yu's tone was slightly heavy.

"Oh dear, look at my memory, I forgot to explain to Fellow Daoist that this set of array discs can only teleport freely within the range of a small continent. Beyond this distance, due to the influence of spatial forces, the teleportation ability is greatly reduced, or even ineffective." The tiger-masked man tapped his forehead with his hand, looking apologetic.

"Forget it. I contacted Fellow Daoist today to ask if you have a way to increase the teleportation distance of the Star Shift Sub-Mother Disc?" Wang Yu frowned, then said.

The other party was clearly deliberately not saying it back then, but he didn't pay attention to this point at the time. Now that the transaction was completed, it was not good to be too concerned about this matter.

"This... I'm afraid not. The distance of a continent is already the limit of the Star Shift Sub-Mother Disc. But if Fellow Daoist wants to teleport over a longer distance, it's not that there are no other ways." The tiger-masked man first shook his head, then changed his tone.

"I would like to hear the details." Wang Yu's heart stirred.

"Actually, this set of array discs is a replica that my friend refined many years ago after comprehending a certain immortal artifact, and can only exert one or two percent of its power. Now, after many attempts, he has barely been able to refine a replica equivalent to one-tenth of the power of that immortal artifact, and named it the Big Dipper Star Disc. I wonder if Fellow Daoist is interested?" The tiger-masked figure said.

"Oh, what is the price of this treasure?" Wang Yu nodded without showing any emotion and asked directly.

If, according to what the other party said, it could have more than five times the power of the Star Shift Sub-Mother Disc, it would be enough.

"If Fellow Daoist can produce six thousand top-grade spirit stones, this thing will be yours." The tiger-masked figure smiled freely.

"You really have a big appetite, this price is more than ten times that of the Star Shift Sub-Mother Disc." Wang Yu said with a gloomy expression upon hearing this.

"You can't say that, you get what you pay for. Although the Big Dipper Star Disc is more expensive, it is definitely worth the money." The tiger-masked man said with a chuckle.

"I really can't produce so many spirit stones at the moment. This is the second time you and I have done business, can you give me a discount?" Wang Yu said after a slight thought.

"This... it's not that I'm unreasonable, it's just that this thing is precious. If my friend hadn't been a little short on hand recently, he originally didn't plan to sell this thing at all." The tiger-masked man shook his head repeatedly.

Wang Yu bargained a few more times, and finally managed to negotiate the price to five thousand three hundred top-grade spirit stones, and then the tiger-masked man was determined and would not reduce the price by a single point.

"If that's the case, I'll give you an answer in seven days, how about that?" Wang Yu sighed lightly and said noncommittally.

"Okay." The tiger-masked man smiled and nodded, then disappeared with a flash of his figure.

Wang Yu took off his mask, and the surrounding cyan light curtain dissipated accordingly, his face clouded with thoughtful contemplation.

A moment later, he released his spiritual sense and inserted it into the storage bracelet on his hand.

In the storage space, all kinds of things had already been sorted and placed by him, divided into more than a dozen categories: monster beast materials, spirit herbs, ores, as well as spirit stones, elixirs, magic weapons, cultivation method books, and so on.

When he left the Black Wind Sea, almost everything on his body was exchanged for spirit stones. Most of these things were scavenged from Fang Pan's storage bracelet.

He now had about three thousand two hundred top-grade spirit stones, which was more than two thousand short of the goal. This gap naturally required him to sell a lot of things.

He didn't dare to sell these things of Fang Pan's casually, so as not to be traced to any clues, but if he traded in the Ever-Changing Alliance, there was no such worry.

Speaking of which, he was quite unfamiliar with the monster beast materials, spirit herbs, and ores in Fang Pan's storage bracelet, and could only barely recognize a small half. Fortunately, he met Sun Ke when he met Zhong Tu.

On the Thunder Ark, he inquired about those things he didn't recognize from Sun Ke in a roundabout way, and basically understood all these things.

This Fang Pan was able to cultivate into a True Immortal Realm mid-stage cultivator who had initially mastered the law of speed, and over the years, he had accumulated quite a fortune. There were many valuable things in his storage bracelet, and even some treasures among them were even more valuable. Adding them all up, it was barely enough for the remaining spirit stones, and there should be some surplus.

Wang Yu immediately took out these spirit herbs, ores, and other things from the storage bracelet, preparing to sell them in batches in the next few days. As a result, when his spiritual sense was about to withdraw, his eyes flickered slightly, and he waved his hand again to take out two boxes, one large and one small.

The large one was a jade box made of some kind of warm jade stone, and inside it was a white giant egg. Because this jade box could continuously provide spiritual energy, this giant egg still had a lot of vitality.

The other small box was about ten feet long, and inside it were three cyan feathers like arrows, with faint cyan light flickering on the surface, looking quite mysterious.

These two things were also obtained from Fang Pan, and were carefully treasured by him, obviously not ordinary things.

Even that Sun Ke didn't recognize these two things, so he could post an appraisal task in the Ever-Changing Alliance to see if anyone recognized them.

……

Seven days later.

In the secret room, Wang Yu, wearing a cyan mask, waved his hand, and a cyan light curtain emerged, quickly contacting the tiger-masked man.

"Hehe, I wonder how Fellow Daoist has considered it?" The tiger-masked man asked with a smile in his eyes.

"Here are five thousand three hundred top-grade spirit stones, are the array discs with you?" Wang Yu took out a storage bag from his arms and said.

"That's natural." The tiger-masked man's eyes lit up and he nodded.

The two quickly reached a cross-border transaction, and the transaction was quickly completed. Two brand-new array discs also arrived in Wang Yu's hands.

This array disc was azure blue, emitting a soft, watery blue light, and the surface was covered with dense lines, much more complicated than the Star Shift Sub-Mother Disc.

There were seven conspicuous white dots in the array disc pattern, forming the shape of the Big Dipper.

The Star-Shifting Stones were inlaid on the two array discs, also eight in number. The color was obviously much deeper, and the light emitted was more profound, as if they were higher-level Star-Shifting Stones.

Stroking the two array discs lightly, Wang Yu's face showed a satisfied expression, but then his brows furrowed slightly.

He had the teleportation array discs, but he was now in the Zhulong Dao, which was hundreds of thousands of miles away from the Black Wind Sea. How could he send one of the Big Dipper Star Discs to the Earthly Fiend Avatar?

"What's wrong, is there something wrong with these two array discs?" The tiger-masked man asked with some doubt.

"This set of array discs is indeed extraordinary, but I have a question to ask you. Is there really no way to increase the teleportation distance of the Star Shift Sub-Mother Disc, even just once?" Wang Yu pondered for a moment and slowly asked.

The tiger-masked man glanced at the two array discs in Wang Yu's hand, and a knowing look appeared in his eyes: "It seems that Fellow Daoist wants to send one of the array discs to another place, right? It's not that there is no way."

"Oh, what is the way?" Wang Yu's heart stirred.

"It's very simple, Fellow Daoist only needs to inlay a grade two Star-Shifting Stone on the Star Shift Sub-Mother Disc in your hand and forcibly activate it, and you can temporarily increase the teleportation distance by several times, but after this teleportation, the Star Shift Sub-Mother Disc will completely collapse." The tiger-masked man said lightly.

"Grade two Star-Shifting Stone?" Wang Yu was stunned.

"It's the Star-Shifting Stone on the Big Dipper Star Disc, the one on the Sub-Mother Disc is a grade one Star-Shifting Stone." The tiger-masked man explained.

Wang Yu nodded, as long as he could send the Big Dipper Star Disc back to the Black Wind Sea, the Star Shift Sub-Mother Disc would be useless, so it didn't matter if it was destroyed.

He then bought some grade two Star-Shifting Stones from the other party. In addition to activating the Star Shift Sub-Mother Disc later, he also kept the rest for future use.
