At this moment, Gu Chuan appeared in the deepest part of the Primordial Kingdom of God, which was also the core of the origin dragon vein. It was surrounded by the suppression power of the Meritorious Xuanhuang Linglong Pagoda, making it an extremely safe location.
"It's time for a period of Closed Door Training," Gu Chuan murmured.
He sat cross-legged on the futon in a lotus position. Previously, he had received a vast amount of the Light of Merit, but in truth, he had only consumed a small portion. A considerable amount remained unabsorbed.
Therefore, he needed time to digest this sharply increased energy.
Once he finished devouring all the Light of Merit, his cultivation base would certainly see a tremendous leap.
Rumble~~
In an instant, centered around Gu Chuan's body, origin energy surged in from every direction across a radius of hundreds of millions of light-years.
The countless pores on his body acted like black holes, freely breathing in energy, resembling a great whale devouring everything around it.
Fortunately, this was a high-grade origin dragon vein, brimming with vast energy reserves. Only such a vein could support his training. A lower-grade dragon vein would have collapsed instantly.
Vaguely, the origin energy seemed to take the form of golden dragons, merging one after another into his limbs and bones. The origin energy within his body was also rising at a speed visible to the naked eye.
In the surrounding space and time, the roars of dragons and tigers could be faintly heard, as if the supreme sound of chaos was being born.
This area was enveloped by a powerful Chaos God Forbidden Formation, which suppressed all signs of cultivation breakthroughs. Without such restrictions, the shockwaves could have affected hundreds of millions of light-years.
Inside his sea of consciousness, the Chaos Universe was also strengthening in sync with Gu Chuan's breathing, becoming more stable and formidable bit by bit.
It was as if the Chaos Universe had turned into a Primordial Ancient Serpent, occupying the chaotic void and swallowing endless chaotic mist and energy, enhancing his physical and spiritual power.
"Strange, why is the evolution speed of this Chaos Universe suddenly accelerating?"
At this moment, the Eater, who was guarding the Gate of Eternal Life, squinted its eyes. It sensed that the expansion speed of this Chaos Universe far exceeded its expectations and was unlike any universe it had encountered before.
Such an evolution was extraordinary. It seemed to be expanding by several light-years every second.
"Is this the vision that emerges when the Chaos Universe is seized?"
The Eater was filled with doubt. Though it had lived for countless years, it had never seen any Lord of the Universe successfully seize a Chaos Universe, and therefore didn't know what the phenomenon should look like.
So it couldn't determine whether this was normal or not.
Regardless, with its current strength, it could not breach the defenses of the Chaos Universe. All it could do was wait for its companions to arrive.
For now, patience was its only choice.
Time flowed like water, and in the realm of chaos, years had no meaning.
During Gu Chuan's Closed Door Training, countless lives across the Chaos Universe were also cultivating diligently—especially the eight disciples of the Ancient Sect (Gu Sect), as well as Sanqing, Zhunti, Jieyin, Fuxi, Nuwa, Zhen Yuanzi, and others. At this moment, they had all encountered great opportunities.
At that time, within Chaos City, a certain manor served as the residence of Nuwa.
Although hundreds of millions of years had passed since the Chaos Genius War, and she had long lost the privilege of living in the elite quarters, she had experienced countless adventures in recent years. She had entered many secret realms and reaped great rewards—gathering a fortune in Chaos Coins.
With her wealth, she bought a manor in Chaos City to serve as her personal residence.
If outsiders entered this manor, they would be shocked. It was no ordinary estate—it was a massive biological laboratory.
Inside this lab were densely packed biological specimens, including creatures from the Prehistoric World, other Great Thousand Worlds, and even corpses of the Zerg Race. She had even captured several grotesques to dissect.
The most advanced experimental equipment lined the walls, and intelligent robots were stationed in every corner, serving as her lab assistants.
The equipment was of such high quality that only elite members of the Mechanic Race could obtain them. These tools weren't available on the open market, yet they were found everywhere within Nuwa's manor.
She had acquired them because she was the personal disciple of the Lord of Chaos City, earning her special recognition and permission to purchase such high-grade equipment.
"It's unbelievable... absolutely unbelievable. The genes of these Zerg creatures are terrifying."
At that moment, Nuwa stood in her lab, staring at the experimental data in astonishment. "Every Zerg creature is genetically engineered. Useless genes are eliminated completely—only the most efficient ones are retained.
These Zerg grow to terrifying levels. Every ten Zerg are like ten perfect killing machines."
In truth, she had studied the bloodlines and genetic structures of countless species across the heavens and myriad worlds. Though she had grasped many secrets of life, the Zerg Race remained a mystery.
Each Zerg was not born naturally, but rather, engineered. Every aspect of their genetic code was predetermined, and they were created in batches—like an assembly line.
Even more astonishing, they could manufacture any type of Zerg as needed, like customized biological weapons. This was not mechanical manufacturing—it was genetic engineering taken to its extreme.
"These are creatures, not machines... Yet the Zerg Brood produces them like machines. This is genetic manipulation at its peak."
"That's right. That's the terrifying thing about the Zerg."
At that moment, a voice echoed through the lab. It was Brain Kong, an advanced AI brain purchased by Nuwa from the Mechanic Race—a device with computational power comparable to the Heavenly Dao.
Nuwa had spent a massive amount of Chaos Coins—even more than the cost of the manor—to obtain it.
But it was worth every coin. This brain had been of immense help in collecting, organizing, and analyzing her research data.
"According to the records of the Mechanic Race," Brain Kong said in a deep voice, "the Zerg Race once stood at the peak of genetic technology. At their height, they could manufacture an entire legion of Chaos Demon Gods with ease.
Fortunately, Lord Father God eradicated them in time. Otherwise, if the Zerg Race had continued to evolve, not a single race in the entire Chaos Universe would have been able to resist them."
