Mount Buzhou Falls, I Use "Rebar and Concrete" to Mend the Heavens!

Time flowed like a river, and ten thousand years passed in the blink of an eye.

During these ten thousand years, the Witch and Demon races recuperated and accumulated strength. The entire Primordial Era outwardly returned to peace, but beneath the surface, turbulent currents surged. The ominous clouds of the second tribulation grew thicker and thicker.

Meanwhile, the Human Race lived a life of peaceful farming in the valley protected by the Innate Grand Formation.

Under Chen Ran's "Divine Revelation," they learned to cultivate land and grow spirit grains; they learned to tame gentle spirit beasts for meat and labor.

The population grew from the initial hundreds of thousands to millions.

The entire tribe flourished, and their level of civilization had taken a qualitative leap compared to ten thousand years ago.

As a result, Chen Ran gained an immense amount of Civilization Power. The spark of consciousness within him had transformed from a tiny flame into a fist-sized ball of light, emitting a brilliant glow of civilization.

And his "landlady," Empress Nuwa, benefited even more.

She stayed in the Wa Empress Palace for ten thousand years, never stepping outside, yet her cultivation advanced by leaps and bounds every day.

Her Saint's Body was strengthened to an unimaginable degree; it was likely that even if she stood still and let other Saints attack her, they wouldn't be able to break her defenses.

The compatibility between her Primordial Spirit and the Great Dao of Creation grew higher and higher.

She was now, without a doubt, the strongest among the Six Saints.

However, only Chen Ran knew all this. Nuwa herself and the Saints outside were still kept in the dark.

All they knew was that Junior Sister Nuwa was becoming more and more unfathomable.

On this day.

Chen Ran was planning the next stage of the Human Race's development – "Institutional Reform" – preparing to establish the preliminary prototype of a nation.

Suddenly, a destructive aura of malevolence erupted from the center of the Primordial Era with a thunderous roar!

The entire Primordial Era world trembled violently.

Chen Ran's heart tightened.

It's here!

The second Witch-Demon war had begun!

And it had arrived earlier and was fiercer than he remembered!

Above the Primordial Era, the Demon Race's Grand Formation of the Stars and the Witch Race's Grand Formation of the Twelve Heavenly Gods and Demons collided fiercely.

Stars fell, and malevolent energy surged into the sky.

Terrifying energy storms swept across the nine heavens and ten earths.

At the center of the battle, Gonggong, the Ancestral Witch of Water, and Zhurong, the Ancestral Witch of Fire, inexplicably abandoned their opponents and began fighting each other.

Water and fire were irreconcilable, and their Daos clashed.

In the end, Zhurong, having the upper hand, heavily wounded Gonggong.

Gonggong, shocked and enraged, filled with grief and indignation, slammed himself into the pillar supporting the heavens – Mount Buzhou!

"BOOM--!!!!!"

A sound beyond description echoed throughout the entire Primordial Era.

Mount Buzhou, formed from Pangu's spine, was actually broken!

The heavens collapsed.

A massive hole appeared in the firmament, and the endless Nine Heavens Weak Water, mixed with chaotic energy, poured down from the rift, as if intending to annihilate all existence.

On the earth, floods raged, volcanoes erupted, and countless beings died in agony.

The apocalypse had arrived!

In the Wa Empress Palace, Nuwa's expression changed drastically.

As a Heavenly Dao Saint, she had a duty to maintain the stability of the Primordial Era.

"I must mend the heavens!"

Without hesitation, she flew out of the Wa Empress Palace and began refining stones to mend the sky.

She took out the Qiankun Cauldron, threw the countless Five-Colored Stones she had gathered into it, and forged them with the True Sun Fire.

However, when she took the refined Five-Colored Stones to repair the hole in the sky, she discovered a fatal problem.

The hole in the sky was too large!

The Five-Colored Stones she had collected were simply not enough!

Seeing the Nine Heavens Weak Water flowing more and more, and the land of the Primordial Era about to turn into a vast ocean, Nuwa was extremely anxious.

"What do I do? I'm still short of at least thirty percent of the materials!"

Just as she was at a loss.

Chen Ran, within her, also grew anxious.

When the nest is overturned, how can any egg remain intact?

If the Primordial Era was destroyed, the Human Race would perish with it, and he, the parasite, would naturally not survive.

"The Five-Colored Stones aren't enough... we'll have to use something else!"

Chen Ran's mind began to race, operating on a level far beyond that of cultivators native to the Primordial Era.

"Mending the heavens is essentially a structural repair project. What's needed are materials with high strength, high toughness, and high adhesion!"

"Science is the primary productive force!"

"System! Immediately expend all Civilization Power to deduce the ultimate application plan for 'Structural Mechanics' and 'Material Science' for mending the heavens!"

Chen Ran almost roared the command.

[Command received! Detecting a life-or-death crisis for the Host, system privileges temporarily elevated!]

[Expending all Civilization Power...]

[Civilization Power -!]

[Primordial Era version of 'Advanced Material Science' and 'God-Tier Structural Mechanics' deduction complete!]

[Ultimate technology unlocked - 'Psionic Cement' formula!]

[Ultimate technology unlocked - 'Innate Geng Metal Rebar' manufacturing method!]

[Related knowledge has been transmitted to the Host's Nuwa Primordial Spirit!]

Boom!

Nuwa, who was worrying about materials, was once again submerged by a torrent of knowledge in her mind.

This time, it was no longer profound runes and Dao techniques.

Instead, it was knowledge she had never seen before, yet instantly understood.

"Using Breathing Soil as a base, combining it with the divine waters of the Nine Heavens, and mixing in powdered Star Cores, then tempering with Samadhi True Fire, can yield 'Psionic Cement,' whose solidity far surpasses Five-Colored Stones?"

"Extracting Innate Geng Metal Qi from the earth's golden veins, compressing and condensing it with great magical power, can form 'Innate Geng Metal Rebar,' whose toughness can support a sky?"

"Using the 'Rebar' as bones and the 'Cement' as flesh, constructing a 'frame structure,' can perfectly mend the cracks in the sky, making it even stronger than before?"

Nuwa was completely stunned.

What... what is all this?

Although it sounded utterly bizarre, the deductions within her Primordial Spirit told her that this plan was entirely feasible!

Moreover, its efficiency was hundreds of times higher than simply using Five-Colored Stones!

"I can't worry about anything else now!"

Nuwa didn't have time to ponder the origin of this knowledge; saving the world was paramount.

She immediately acted according to the methods in her mind.

With one hand, she reached towards the earth, forcefully drawing out endless Nine Heavens Breathing Soil and the Innate Golden Veins.

With the other hand, she summoned the divine waters of the Nine Heavens and stars from beyond the domain.

In the Qiankun Cauldron, the True Sun Fire burned fiercely.

Under the shocked gazes of all the Saints and other powerful beings.

Nuwa did not refine Five-Colored Stones anymore. Instead, she began to refine a gray, mud-like substance, and golden, dragon-like "metal bars."

"What is Junior Sister Nuwa doing?"

"That's not refining a weapon, nor is it alchemy... what is that?"

"I don't understand, not at all..."

Just as everyone was filled with doubt, Nuwa made her move.

With a wave of her delicate hand.

Countless strands of "Innate Geng Metal Rebar" flew towards the gaping hole in the sky, instantly weaving into a massive framework covering the entire void, arranged in a profound mechanical structure.

Immediately after, she poured out the "Psionic Cement" from the Qiankun Cauldron.

Those gray mud-like substances precisely filled every gap in the "rebar framework."

Catalyzed by Nuwa's Saintly power, the "Psionic Cement" solidified at an astonishing speed.

The terrifying abyss that devoured everything was... mended!

Moreover, the newly mended section of the sky appeared even thicker and sturdier than the surrounding firmament!

All living beings in the entire Primordial Era who witnessed this scene were petrified.

They... mended the sky with mud and iron bars?

Isn't this scene a bit... off?
