The small island shattered, the beast tide was vast and boundless. In the middle of the beast tide, the island was like a rootless duckweed.

The boundless Thunder Beasts, the vast majority, passed by the flanks of the great formation, continuing to surge eastward. However, a portion of the Thunder Beasts, because the great formation was precisely blocking their path,

They…

Came crashing in.

These Thunder Beasts had no intelligence. They charged forward, smashing everything in their path. They didn't know to go around obstacles and continued to charge, only mechanically colliding with whatever was in front of them.

Boom!

Boom!!

Boom!!!

These Thunder Beasts charged at the great formation like madmen. With every collision, countless Thunder Beasts shattered themselves to death.

The two people and one dog watched the scene outside with pounding hearts.

With every collision, the great formation shook violently, looking as though it could collapse at any moment.

The great formation was very sturdy. It could easily withstand any single Thunder Beast or even a group of them, but what lay before them was a tide of Thunder Beasts, surging in ceaselessly.

Countless Thunder Beasts collapsed and died, yet their successors pressed forward, still desperately crashing into the great formation.

The great formation shook more violently.

The two people and one dog watched for a long time. Seeing that the Thunder Beasts could not break through the great formation, the anxiety in their hearts finally eased a little.

"Crack!"

A crisp sound, like a demon's whisper, reached their ears, making them tremble.

They looked up in disbelief. A crack had appeared above the great formation.

The two people and one dog knew that even though it was only a tiny crack, it was the beginning of its destruction. This was the difference between zero and one.

Either it could withstand it completely, or it would completely collapse.

"Gouzi, Gouzi, didn't you say these Thunder Beasts couldn't break the great formation?"

"How would I know? This is a formation laid out by a Grandmaster! How could it be broken by these low-level Thunder Beasts?"

Gouzi immediately replied.

Fang Xiaoyu frowned and suddenly asked,

"This formation hasn't been maintained for fifty thousand years. Could it be that the formation has weakened, and that's why it's being breached?"

After all, everyone knew that whether it was a fixed teleportation array, a sect-protecting formation, or a sealing formation, they all required formation masters to maintain them every few years.

Nothing in this world lasted forever; everything had an expiration date.

"Yes."

The one who spoke was the stone tablet.

"Damn it, Squirrel, don't screw your dad over! What do we do now? If the great formation breaks, we'll all die."

"It can be maintained by a formation master, and the formation needs to be maintained during the beast tide attack."

"But there's no formation master here, only an apprentice."

The little yellow dog pointed at Wan Lei.

"Make do with what you have."

"No, can't you just spew out some runes and repair the formation?"

"My highest mastery is Grandmaster level formations. The Primordial Chaos Array is a Grandmaster-level formation. I... I don't know how."

"If you don't know how to repair it, why don't you have Wan Lei do it?"

"He has the array eyes. If I give him control of the Primordial Chaos Array, there's a slim chance he can repair it. Even if he can't repair it, he should be able to stabilize it."

"Hurry, hurry."

The little yellow dog was extremely anxious, urging the stone tablet non-stop.

A stream of light instantly appeared within the stone tablet and entered Wan Lei's sea of consciousness. In an instant, the formation diagram of the Primordial Chaos Array appeared in Wan Lei's mind.

But... the complexity of this formation diagram made Wan Lei feel completely lost.

It was like he was a math prodigy, but still in elementary school. He could solve linear equations smoothly, but now he was presented with higher mathematics.

No matter how talented he was, he absolutely couldn't solve it.

But at this moment, he had to step up no matter what. At the very least, he had to stabilize the great formation with its authority.

Wan Lei flew up into the air and arrived mid-air. He activated the array eyes, and instantly, throughout the Primordial Chaos Array, the originally transparent formation barrier displayed streams of flowing runes, visible to his eyes.

Wan Lei immediately channeled his own lightning power into the crack, trying to mend it while fully dedicating himself to controlling the great formation.

At this moment, all of Wan Lei's divine sense power entered the great formation, as if he had merged with it.

The surrounding Thunder Beasts surged eastward.

The Thunder Beasts on the west side of the great formation continued to crash into it furiously.

Ahead, Thunder Beasts charged to their deaths against the great formation fearlessly, while those behind them quickly followed, as if the great formation had some deep-seated hatred with them.

The great formation continued to shake and tremble. With every tremor, it rebounded onto Wan Lei.

These repeated impacts were like a massive hammer, smashing down on Wan Lei like a storm.

"Little Lei, hold on! I've observed this. This might be the normal migration of the Thunder Beasts. Once they pass, it'll be fine."

The little yellow dog shouted loudly.

Wan Lei had already activated his lightning armor, but it still couldn't withstand the intense damage from the repeated impacts.

Moreover, he also had to supply energy to the great formation, using his own energy to maintain it.

Crack!

Another crack appeared on the great formation.

Wan Lei had no choice but to inject more energy into that crack.

But if this continued, no matter how much energy he had, he couldn't sustain the endless consumption of the great formation.

The Thunder Beast tide in the distance was still boundless.

"Ah!!!"

Cracks appeared more and more frequently. Wan Lei was already giving his all, roaring, pushing his array eyes to their limit, desperately maintaining the great formation.

He felt a tearing pain all over his body. Each impact worsened his injuries. He had to use his lightning power to heal himself while also maintaining the formation. His lightning power was already depleted.

An hour later, the lightning power in Wan Lei's dantian was completely exhausted.

The beast tide showed no signs of ending.

The little yellow dog scurried back and forth anxiously, constantly demanding materials to maintain the formation from the stone tablet.

Fang Xiaoyu, holding a laser gun, stood inside the great formation, furiously attacking the Thunder Beasts outside.

She didn't understand formations and couldn't help much. She could only do what she could.

Although her attacks were like a drop in the bucket.

Wan Lei's lightning power in his dantian ran out, and he had no choice but to use the lightning power from his primordial lightning essence.

The lightning power within his primordial essence replaced his dantian, continuing to supply energy to the great formation and heal Wan Lei.

The attack of the Thunder Beast tide outside became even more frenzied. The moment the attack intensified, Wan Lei's body began to crack.

He was wearing armor and a mask, so his appearance was not visible from the outside, but he knew his own condition. He was truly at his limit.

The lightning power within his primordial essence was rapidly depleting. Wan Lei channeled all his usable power into maintaining the great formation.

His dantian, primordial essence, divine sense power, physical strength, and even the energy rings within his wings were all mobilized.

And all of them... were also exhausted.

At this point, Wan Lei could only resort to the last resort.

Self-detonating his primordial lightning essence.
