After becoming slaves, none of those people dared to speak directly to Alu. But Cherish did. It was clear that she still couldn't consider herself a slave.
"Hmph." Alu snorted coldly when he heard Cherish's question.
His relationship with Elizabeth has always been a knot in his heart. He didn't even like to think about it, let alone hear other people talk about it.
He then looked at Cherish with cold eyes. "This isn't something a slave like you should ask." Alu replied in a cold tone.
Alu's answer angered Cherish. But since she couldn't do anything to Alu, she, in the end, could only lower her head while gritting her teeth.
Whooss...
When Cherish was lowering her head, Alu suddenly appeared in front of her.
"I didn't kill for your behavior, but you still have to get one punishment." Alu said.
Bam...
After saying that, Alu slapped Cherish in the face once again.
Cough...
Cherish immediately coughed up blood the moment her face was slapped.
Her body staggered a few steps back.
As she looked at Alu, her expression was immediately filled with anger. Spiritual energy nearly erupted from her body.
But she chose silence in the end.
Alu ignored Cherish's anger. He acted as if nothing had happened.
He then looked at the people.
"Now immediately use the concealment formation I gave you. We will go now." Alu said one more time.
Even though the formation had many advantages, it actually had some disadvantages as well. Especially for low level formations.
The most basic drawback is that it requires a supply of energy to maintain it. If there is no energy supply, the formation will disperse in some time.
Formations could still be supplied with ordinary spiritual energy, but that naturally wasn't as good as using spirit energy. The formation time can last much shorter.
When a formation was used by ordinary cultivators, they could only supply the formation energy with ordinary spiritual energy. Unless they have spirit stones that contain spirit energy. However, spirit stones were far rarer than spiritual stones, and they weren't something that most ordinary cultivators could possess.
In reality, the spirit formations protecting certain places such as cities or sects always had several people tasked with supplying energy to the formation.
Even a Nirvana level formation still needed a supply of energy from people.
Of course, there were also formations that could maintain their existence by themselves. But it was only a high-level formation created by an extremely powerful spirit master.
Such formations usually had the ability to absorb the surrounding spirit energy to maintain its existence.
But even such a formation would normally weaken over time.
Without constant care, nothing can last forever.
Like Adon who was able to maintain the formation he created before he entered the holy path must have paid a very high price to maintain it.
But there was also one advantage to spirit formation.
Like Adon, every spirit master can strengthen their spirit formation so that it surpasses their own cultivation realm.
A Mortal stage spirit master can strengthen their formation until it reaches Nirvana stage.
Of course, doing so would require not only hard work, but also countless resources. Most spirit masters didn't have enough resources to do that.
After hearing Alu's words, they quickly used their concealment formation.
They threw the core of the formation into their chests, and in an instant, their figures completely disappeared.
They couldn't sense each other's existence if not through the tracer jade.
Of course, as the one who set up the formation, Alu could still sense their presence even if they weren't holding the tracer jade. The formation, however, was created using his spirit energy. He could naturally sense the presence of his own spirit energy.
After their figures disappeared, Alu once again threw a transparent figure into his chest.
"Let's go." Alu said after his figure disappeared.
After that, they immediately flew after Alton and Callie.
They were flying at full speed.
Even though they were quite a distance away, with their flying speed, they would definitely catch up with Adon's group in some time.
Unlike them, Adon's group flew more slowly.
However, even though they were flying very fast, they did not make the slightest disturbance to the environment they were passing through.
Normally, when they passed through the wisps of clouds, they would definitely sweep away the wisps of clouds they passed.
But right now, as they passed through the wisps of clouds, they didn't move an inch. No one would have thought that the place had just been passed by several people.
A concealment formation that originated from the Universe Formation clearly couldn't compare to a normal concealment formation.
For most concealment formations, they only hide the figures of the people who use them. That's the simplest concept.
But the concealment formation that originated from the Universe Formation had a completely different concept.
Rather than calling it hiding the person using it, it would be more correct to call it moving the location of the person using it.
Basically, it moved the location of the person using it to a completely different dimension.
Alu and the others didn't make any distraction while they were flying basically not because they didn't make any disturbances. It's just that, the distraction they create is in a different dimension.
The stronger the formation, the deeper the dimension it could enter.
Even the formation Alu created, even though it was only a mortal stage formation, but the dimension that the formation could enter was a dimension that even low-level Nirvana experts could not achieve.
Because of that, a low-level Nirvana expert basically wouldn't be able to sense Alu's existence if he used his concealment formation.
Sometime later, Alu and the others arrived at the previous cloud island.
But unlike before, there were no more formations covering the island.
The island was completely open so that people could enter from anywhere.
At this time there were quite a number of people on the island and many of them fighting over the good spots on the island.
When passing the island, Alu stopped for a few moments. He had no interest in the people on the island. However, when he saw the island, he could feel traces of spirit energy from Adon's formation.
What attracted Alu was, the spirit energy on the island was actually already much stronger than the last time he saw it.
"No wonder Adon dares to challenge Elizabeth. His current formation can definitely kill the weakest Nirvana stage."
It was just the most basic of judgments as he was only judging through the traces of Adon's spirit energy. As for actual strength, it definitely exceeded his expectations.
"Even if I unleash the full power of Nirvana's spiritual weapon, I might not be able to destroy it." Alu said to himself.
"Luckily I've planted a mark on Adon's formation."
When thinking that, Alu couldn't help but smile.
No matter how strong Adon's formation was, Alu didn't feel worried because the mark he planted on the formation allowed him to control it as long as the earring ball or formation disc his mother had given him was under his control.
His control may not be as strong as Adon's control because that formation, however, is a formation that Adon created himself. However, he still believes he can make Adon unable to harm him with his own formation.
Alu chuckled as he thought that.
Not being able to harm an enemy while the enemy was inside their own spirit formation was water to any spirit master. It could even break a spirit master's resolve.
Whooss...
Alu and the others only stopped briefly before continuing on their way.
They passed the island before flying any further.
And the farther they went, the clouds around them also became thicker and wider.
The clouds seemed to be starting to coalesce and if one could see from the outside, they would look like an ocean.
"Looks like the fight will take place in the main place." Alu said while looking ahead.
The direction Adon's group was heading was actually the place where the mysterious spiritual aura originated.
As Alu passed by the people, he had heard various rumors about the place.
He also asked Cherish and the others. But none of them gave a definite answer. They had never been to that place either.
After nearly an hour of flying, the distance between Alu's group and Adon's group was getting closer.
Even though they couldn't see Adon's group yet, they could already feel their auras.
Of course, apart from Alton and the others who were carrying tracking jade, not a single person in Adon's group could sense their auras.
Within Adon's group, apart from Alton and the others, Alu could feel nearly twenty auras.
As the strongest among the younger generations of the thousand islands region, Adon naturally could easily gather followers.
Even if he didn't say it, there would be quite a number of people coming to him. After all, for those who wanted to join the Spiritual Academy, becoming a follower of Adon would naturally ease their life in the Spiritual Academy.
"Now slow down." Alu said as he felt the aura of Adon's group.
Since they were close, they only needed to follow them behind.
Now they just have to wait for Adon and Elizabeth to meet.
