Wu Yun stayed inside Seven Seas King's World Ring. After all, they belonged to different camps.
He had enslaved Seven Seas King too quickly. The other man hadn't had time to call for help or send a signal through the Military System, so Wu Yun naturally wouldn't let his identity slip.
"Beep~"
Lanzang City Lord sent him a call request. He often kept an eye on Wu Yun's location in the Outer Realm Battlefield, and was surprised to see him at the Ten Thousand Tribulations Prison.
"Teacher," Wu Yun greeted him.
Lanzang City Lord frowned. "Why does your location show that you're at the Ten Thousand Tribulations Prison?"
He also meant to ask: You wouldn't dare go to a battlefield like this just because you have Supreme Treasure Armor, would you?
The most monstrous World Lord could reach the twentieth level of the Heavenly Bridge, and with all sorts of opportunities on top of that, it was normal to have High King-level strength. The question was whether Wu Yun actually had that strength now.
"Teacher, I just gained a Soul Slave named Seven Seas King."
Wu Yun explained with a smile, "Please believe me. I have the strength to venture into any King-level battlefield."
Lanzang City Lord was utterly astonished.
Although King-Level Immortals were minor figures to them, a Universe Master's terrifying memory and intellect meant it only took a moment to figure out Seven Seas King's strength.
"You can enslave a Peak King?!" Lanzang City Lord blinked. That was far from as simple as killing one.
Enslaving and killing were two different things.
Killing was easy. For example, an Invincible King who burned part of his Immortal Divine Body could, under special circumstances, force a Peak King to self-detonate.
But enslavement was much harder. When a Peak King had only fifty percent of his Divine Body remaining, he would often self-detonate outright, leaving no chance to enslave him.
"I had some good fortune." Wu Yun didn't want to lie, so he glossed over the details.
Lanzang City Lord didn't press him. Everyone had their own secrets. The dozen or so Universe Masters in the Human Race had all encountered various opportunities when they were World Lords or Immortals.
Some had possessed Special Lifeforms or Golden Horned Beasts; others had come across the inheritances of powerful beings from the Alien Race.
There was no point asking about such things. Lanzang City Lord only needed to know that Wu Yun was his disciple. His protective instincts immediately kicked in. "Your identity as Wu Yun has hardly ever been exposed in the Human Territory. Now that you've taken care of this identity, no one will suspect you're a World Lord."
"Yes." Wu Yun could feel Lanzang City Lord's concern.
To enslave a Peak King as a World Lord—Luo Feng hadn't even been born yet, and Wu Yun had already reached a height countless human geniuses could scarcely hope to attain.
Of course, there had been a few World Lords in history who could do it, such as those monstrous ones who possessed Special Lifeforms, whose Gene Level reached a thousand times the norm.
Or an unparalleled figure like Darkness Master.
"Once you're done exploring the Outer Realm Battlefield, find an opportunity to break through the Primal Heavenly Mountain." Lanzang City Lord couldn't hide his smile. "If Void Gold Master and the others knew how strong you were now, they'd surely regret betting with me."
Those supreme beings occasionally placed bets over their juniors, putting one or two Supreme Treasures up as the stakes.
After Seven Seas King entered the Ten Thousand Tribulations Prison, Wu Yun sent his consciousness through the World Ring to cover the outside. He could detect everything within a radius of ten billion kilometers.
An ordinary True God Dao Ancestor could cover the Three Realms with a single thought, let alone Wu Yun, who had reached the fifth level of Heart Power. A brief search revealed two or three King-level teams.
Hundreds of thousands of Kings had gathered at the Ten Thousand Tribulations Prison. Though the place was vast beyond measure, there were only so many safe areas. Most prison districts were uninhabited.
Kings from the various camps occupied all the accessible areas, and a casual sweep revealed countless Peak Kings.
"Even Initial Kings probably wouldn't dare come here." Wu Yun considered what level of strength he should reveal. Anything beyond Invincible King, or even Invincible King itself, was out of the question.
If an Invincible King appeared on the Outer Realm Battlefield, the Invincible Kings from the other peak races would enter the fray too. That would create too many problems.
Coming to the Outer Realm Battlefield to kill enemies and earn military merits was one thing; Wu Yun was more interested in obtaining resources.
Showing strength beyond Invincible King would be even worse. Against King-level experts, Universe Venerable-level strength would be utterly devastating. The Universe Venerables might get involved.
So he'd just reveal strength on the level of Life-Ending King or Seven Swords King.
"Master, the emergence of a treasure trove is only one kind of opportunity," Seven Seas King said telepathically. "With countless races from the four camps gathered here, King-level battles break out all the time."
"I know. Don't rush."
Wu Yun had no intention of killing Kings for money just yet. With strength like his, he naturally intended to seek the natives' treasures.
After entering the Ten Thousand Tribulations Prison, he saw that the entire universe was dim and hazy, a sign of its depleted energy. Lifeforms in a Universe Secret Realm were already inferior in potential.
The lifeforms in this Universe Secret Realm were now a level lower still.
The stars were just as dim. The stars had burned out, no longer giving off even a glimmer of light. The prison districts' scattered starlight was all that illuminated the place.
Seven Seas King flew for several days. They also came across dozens of King-level teams, but found no trace of the natives.
"Forget it. Let's split up," Wu Yun said, quietly emerging from the World Ring. "Send a Soul Slave to follow me, and give him the token. That way, we can use Divine Kingdom Teleportation if anything comes up."
As a King-level powerhouse, Seven Seas King was also quite skilled with souls, and had plenty of Marquis-level slaves.
In Seven Seas King's eyes, Marquis-Level Immortals were expendable—tools to explore dangerous regions.
Seven Seas King sent a Peak Marquis to follow Wu Yun, while he himself flew in the opposite direction.
After experiencing this universe firsthand, Wu Yun felt uncomfortable all over.
His God-Demon Body Refining replenished energy by absorbing the starlight in the universe, enough to sustain normal combat with every breath.
But here, energy was scarce and the stars were dim—or rather, the energy had retreated inside the celestial bodies, leaving almost nothing to absorb.
"I'd better use World Lord Power to travel." Wu Yun had to conserve his True God power. By his estimate, he could unleash his full strength at most a hundred times before running dry.
The restrictions were severe when crossing between different world systems.
Still, Wu Yun suspected he could recover by absorbing Fire God Source Crystals. If he ever ventured into such a remote region of the universe again, he'd need to prepare some energy items.
After spending several months apart from Seven Seas King, Wu Yun witnessed several King-level battles. Some were between the Machine Race and the Bug Race, while others pitted humans against the Monster Race.
Quite a few High Kings and Peak Kings fell.
Wu Yun watched the battles coldly. A vague feeling stirred within him, telling him the natives' treasure trove was nearby.
Cultivators always had certain uncanny feelings about fate.
As Wu Yun set foot on another desolate star, he narrowed his consciousness to a radius of a million kilometers, enough to search every area precisely.
"Hm?!" Wu Yun suddenly discovered that the star was only a little over three thousand kilometers deep. The rest of it seemed to be hollow.
