**Chapter 2861: Time Reversal, Waiting for Rain and Thunder!**
Twelve days later, the origin shuttle stopped in front of a city.
Lin Moyu slowly opened his eyes, and in his soul world, the third Dao pattern was shining brightly.
In twelve days, multitasking, he successfully condensed the third Dao pattern.
At the same time, he made progress in his research on merging two types of formations.
With a little more time, he could succeed.
Through the origin shuttle, Lin Moyu saw the situation before him.
In front of him was a ruin, and from the scale of the ruins, it was clear that it was once a medium-sized city.
Lin Moyu left the origin shuttle, personally sensing the lingering aura here.
"There must have been a great battle here, with lingering origin power."
"This origin power..."
"Comes from the demon race!"
Lin Moyu was seventy percent sure that the city was destroyed by the demon race.
The lingering origin power was still strong.
With a slight smile, he activated the Eye of the Undead and saw that many soul flames were still hidden within the city.
Though they tried to hide their aura, they couldn't escape Lin Moyu's perception.
"Just right, the Bone Hell needs feeding!"
Lin Moyu snapped his fingers, space twisted, and the Bone Hell descended silently.
Magma flowed everywhere, and the Hellish Fiends pounced like wolves.
But they couldn't move faster than the Eye of Hell, which opened, sweeping with a powerful soul impact, shattering the soul flames hidden in the city.
The corpses were then devoured by the Hellish Fiends, leaving nothing behind.
In an instant, the entire ruin was leveled.
The ground looked as if it had been plowed anew, perfectly flat.
The Hellish Fiends truly devoured everything, regardless of what it was.
Lin Moyu even suspected that given enough time, they could devour the entire Origin Continent.
And the Great Dao, could they even devour humanity?
So far, Lin Moyu hadn't found anything they couldn't eat, only a few things they couldn't yet chew through.
The Hellish Fiends were indiscriminate eaters, accepting all.
Lin Moyu walked into the former city area, his gaze wandering around.
"The Thunder Vault should be here, so why can't I see it?"
"The Lu Feng Merchant Association's information shouldn't be wrong, so why?"
He trusted the Lu Feng Merchant Association's information, but now even the ruins were cleared, and the ground was like a gray wasteland, with no sign of the Thunder Vault.
Lin Moyu wasn't in a hurry; he went to the center of the former city, "Let me see!"
The Time Great Dao appeared beside him, its flow enveloping the surroundings, the power of the Great Dao vibrating, and time began to reverse.
He wanted to see what had happened to the city, how it was destroyed, and where the origin vault was.
Now that he had reached the peak Heavenly Sovereign level, he was much stronger than when he first arrived on the Origin Continent.
His understanding of the Time Great Dao had deepened, allowing him to reverse time.
His soul had also reached the Dao Sovereign Third Realm, an important foundation for time reversal.
Under the Time Great Dao's influence, the time imprint of the city began to appear in his vision.
First, the ruins appeared, leveled by Lin Moyu using the Bone Hell.
Then the ruins reappeared, and events that had occurred there began to unfold.
Not long ago, human cultivators had arrived.
Three Heavenly Sovereigns came, all mid-level, clearly on a training mission.
After arriving, they were ambushed by the demon race, and the three fled, their whereabouts unknown.
Going further back, more humans were ambushed by the demon race, with several killed.
Continuing back, human cultivators kept coming, some strong enough to counterattack after being ambushed.
But after exploring for a while, they found nothing and left.
Time kept rewinding, and in a year, dozens of battles occurred, almost one every few days.
Many demons died, and human cultivators weren't spared either.
Such battles were common across the Eastern Continent.
Through a year's time reversal, Lin Moyu had his answer.
There must be something wrong here, or the demon race wouldn't keep coming.
As time reversed further, the consumption of soul power increased.
After just two years, the consumption of soul power exceeded the World Tree's replenishment rate.
"Three years should be enough; in the Great World, I could reverse time for a million years."
"But now, on the Origin Continent, I can only reverse three years; the gap is still vast."
Lin Moyu felt he was getting closer to the truth and continued the time reversal.
Finally, at two and a half years, it started to rain where the city stood.
Over two years, it had rained many times, but this rain was different.
This rain was a thunderstorm!
And as the rain began, several demon Dao Sovereigns appeared in the ruins, along with human Dao Sovereigns.
There weren't many, about five on each side.
They faced off in the rain.
The sky turned black, clouds covering the sun, and a thunderclap sounded.
The origin vault appeared in the scene.
In an instant, Lin Moyu's soul power consumption skyrocketed, increasing hundreds of times.
The time reversal abruptly stopped, and Lin Moyu's face turned pale.
In that moment, his soul power was nearly exhausted.
The World Tree worked to replenish Lin Moyu's soul power, and his aura gradually recovered.
"What just happened?"
"When the Thunder Vault appeared, my soul power consumption spiked."
"Could it be that my Time Great Dao, when reversing to the origin vault, causes a massive soul power drain?"
"Ordinary origin vaults shouldn't do this, unless this one is unusual."
"The origin vault must involve the origin Great Dao, making it difficult to reverse."
"That's the only explanation; there must be a secret in this origin vault."
"The Thunder Vault needs a thunderstorm to appear?"
"If so, I'll have to wait!"
Lin Moyu looked at the sky; it was clear with no clouds, so rain wasn't coming soon.
He recalled the rains he saw during the time reversal, which started suddenly.
One moment it was clear, the next it was pouring.
But not every rain brought a thunderstorm; ordinary rain couldn't reveal the Thunder Vault.
If he had to wait, it might take some time.
Lin Moyu thought, "Why not try?"
He summoned the Thunder Light Purple Striped Tiger.
The Thunder Light Purple Striped Tiger controlled the Thunder Great Dao, and it followed Lin Moyu's command, summoning the power of the Great Dao.
In an instant, thunder rumbled in the sky, and light danced.
But nothing happened around; the Thunder Vault didn't appear.
"Looks like I'll have to wait for a real thunderstorm."
"Who knows how long that will take!"
Lin Moyu put away the Thunder Light Purple Striped Tiger and retreated over a thousand kilometers.
He casually set up a fourth-level formation to hide his aura.
He waited for the thunderstorm, multitasking by condensing the fourth Dao pattern and studying formation fusion.
