After returning to King Huo Yi's palace, Zhang Dong went straight to the quiet chamber deep inside and repeatedly instructed Gao Li not to disturb his cultivation under any circumstances.
Once the secret chamber's door had closed, Zhang Dong still habitually inspected his surroundings first. Only after confirming that it was safe did he send his soul power into the Jade Green Bubble.
Whoosh!
In the blink of an eye, he crossed endless spacetime and arrived on the Boundary Heart Continent.
A completely different set of rules emerged. It was as if an invisible chain shrouded the world, binding every living being tightly.
In the Primordial Universe, Zhang Dong could shatter stars with a flick of his finger and manipulate them at will. But here on the Boundary Heart Continent, his most pressing task was to find a way to fly.
Even True Deities on the Origin Continent couldn't fly. Things were a little better on the Boundary Heart Continent, but one still needed the strength of the True Deity Heaven and Earth Realm, or to be an especially powerful Fourth Heaven Realm Deity, to manage it.
The next moment, a vast torrent of memories began pouring into the depths of his true self's soul.
The memories from these years were monotonous: cultivation, and nothing but cultivation. But the details of that cultivation were immense.
Research into various Second-Class Divine Hearts, True Intents, and secret techniques.
Was he still just a little short of comprehending a First-Class Divine Heart? Zhang Dong wasn't in a hurry. At his current level, he would comprehend a Pole Divine Heart within five years at most.
His true self wasn't in a hurry to become a World God just yet, either. His main purpose in coming to the Boundary Heart Continent was to share memories.
After staying on the Boundary Heart Continent for three days and replenishing his energy, Zhang Dong returned to the Primordial Universe.
During his Domain Lord stage, he had rarely spent time in a Nutrient Pod to level up. He'd used most of his time to study the laws. In Zhang Dong's view, spending time in a Nutrient Pod was a waste.
After arriving on the Boundary Heart Continent, he only had to take a breath for endless energy to pour into his body.
Zhang Dong used that energy precisely to advance his Primordial Universe system to the Domain Lord level. If he wished, he could break through to the Realm Lord level at any time.
With a little more time spent breathing, he could reach the ninth Realm Lord rank.
The Feather Slaughter Clan, Huoyi Palace.
"Gao Li."
Zhang Dong pushed open the secret chamber door. "Come on. I'll contact King Huo Yi now, and we'll get ready to visit the Chaos Heaven Mirror."
Gao Li had already come over at the sound of the door opening. He was used to Zhang Dong suddenly entering seclusion to cultivate.
Geniuses were like that. They could have an epiphany at any moment.
King Huo Yi had also been waiting in the palace for Zhang Dong. Elder Xu Jin's orders had clearly stated that Zhang Dong was very likely to become a benefactor to the Feather Slaughter Clan in the future.
There had been precedents.
The Hong Alliance once had a Subordinate Clan with only three Cosmic Venerables. Its standing was low, but it had formed a good relationship with a certain Universe Master while he was still weak.
After that Universe Master rose to prominence, he naturally looked after the Subordinate Clan. They no longer had to handle dirty, exhausting work, and they received more resources, giving their clan a much better chance of rising.
The Chaos Heaven Mirror was in the Elder Hall. It wasn't much trouble to get there. The continent was small, after all, and King Huo Yi could reach any area with a single Teleportation.
After passing through the corridor and reaching its end, Zhang Dong saw a Bronze Gate a hundred meters tall before him.
A gray-robed figure stood at the entrance. The aura he gave off was clearly at the King Level. When he saw King Huo Yi and the others arrive, the Gray-robed Man said nothing, merely opening the Bronze Gate in silence.
Boom!
The gate slowly opened, revealing a very plain quiet chamber.
At its center, on a stone platform about twelve meters long and eight meters wide, rested an ancient mirror. It stood there as if it had existed for hundreds of millions of years, covered in dust.
The mirror was perfectly round, about half a meter in diameter. Its surface was murky and indistinct, reflecting nothing at all. A mist that had never lifted since time immemorial veiled it.
From the outside, it looked like an utterly ordinary mirror.
But there had to be a reason it was said to rival a Chaos Stele and even surpass one in certain ways.
"Your Highness, simply enter the mirror," King Huo Yi explained. "Ordinary members of our clan can only meditate inside for half a month. But Elder Xu Jin gave special orders that Your Highness may meditate as long as you wish."
Since Elder Xu Jin had decided to forge a bond, he naturally wanted to do everything he could.
"I'll remember Elder Xu Jin and the Feather Slaughter Clan's kindness," Zhang Dong said with a smile. "I'll go in now."
When he came within two meters of the mirror, Zhang Dong sensed the Realm Within Realm inside it.
He had already examined it from the outside. It was an extremely ordinary mirror. Its material was no less valuable than some precious metals, but it could hardly be called a clan-protecting treasure.
The space inside the mirror was completely different from what he'd imagined.
Rather than being a vast, boundless world, it was cramped and bitterly cold. A weaker Star Level being would probably freeze into an ice statue the instant they arrived.
The space was only slightly larger than the stone platform outside. No wonder only one person could meditate there at a time. If it had been spacious enough, the Feather Slaughter Clan would have sent all its talented members inside long ago.
But the environment was somewhat like the universe, with countless transparent fragments floating about, faintly revealing something mysterious.
Zhang Dong casually grabbed one and turned it over in his hand.
"Huh?!" Zhang Dong was astonished to discover that the countless particles and even Micro-Particles within the fragment he'd grabbed were completely still.
That was the mystery of Time Stop!
No wonder Elder Xu Jin had said this place was unfathomable, on par with a Chaos Stele.
For cultivators of the Time Law, it was even more astonishing than many Chaos Steles. What Zhang Dong didn't know was that ordinary geniuses who entered couldn't observe particles or Micro-Particles at all.
Only when an Immortal God self-destructed was the space of the universe shattered into streams of particles.
The Feather Slaughter Clan's geniuses, and even many Immortal Gods, could see no more than the fragments' overall mysteries when they came to meditate. In terms of artistic conception, it was even inferior to the Universe Chaos Stele.
Every Micro-Particle was in a state of absolute stillness.
Zhang Dong picked up another fragment to examine it. The countless Micro-Particles inside this one were moving.
They were moving very fast, clearly at a rate of time entirely different from the outside.
Every fragment held different mysteries. The more basic ones concerned the essence of time, while the deeper ones fell into three categories.
The three categories of the Space Law were Teleportation, Space Seal, and Space Strangle. The branches of time were Time Acceleration, Time Deceleration, and Time Stop.
In the Tianyu Universe, the complete Time True Intent was a First-Class True Intent.
Time Acceleration, Time Deceleration, and Time Stop were all Second-Class True Intents. Acceleration and deceleration might both seem to control the flow of time, but their principles were completely different, as were their uses in battle.
"This place really is an incredible opportunity for me!" Zhang Dong was overjoyed. His ability to observe Micro-Particles surpassed even that of King-level Immortals.
The reason laws were so difficult to comprehend was that they were so profound and mysterious.
When comprehending the Dao, nothing was worse than vagueness. Others could find it unfathomably mysterious, but you had to know clearly what you were trying to comprehend.
Observing the state of Micro-Particles under Time Stop and Time Deceleration was like seeing the laws made tangible.
