While Martin was concentrating on dealing with memorials in the palace, an earth-shaking event was taking place in the plane of hell.

Without warning, the core of the plane burst into a blinding light.

In an instant, the entire hell plane trembled violently, as if it had been baptized by some powerful force and began a large-scale recasting.

The plane core is fully protecting the seven deadly sins in the core of the earth, under the influence of this mysterious force.

The mountains, rivers and land of hell seemed to be controlled by an invisible force. They first broke and shattered, and then reassembled, and this cycle continued over and over again.

After an unknown amount of time, the core of the plane quietly underwent obvious changes. At the same time, golden energy spread out like ripples from the core.

All creatures in the hell plane, without exception, are blessed by this golden energy.

The seriously injured demons began to slowly recover from their injuries under the nourishment of this magical energy.

The original seven deadly sins in the core of the earth were also affected and gradually came back to life.

After an unknown amount of time, the strength of the demons had increased dramatically. Many demons recovered to the star level, and some even broke through to the star cluster level.

After recovering their strength, they immediately returned to the Hell Plane through the Plane Channel.

Returning to hell, they were surprised to find that everything here was completely different from before.

The original fertility ground is now full of vitality and begins to produce a large number of little demons.

Not only are the number of little demons born far greater than before, but each little demon is also stronger than before.

The demons gathered together, and those who broke through to the star cluster level were busy forming gangs and factions, all coveting the throne of the hell plane.

For a moment, the demons were arguing with each other, their swords drawn, and they were almost about to fight.

At this critical moment, deep in the core of the hell plane, the original seven deadly sins slowly opened their eyes.

They exchanged glances, and there was a naked bloodthirsty light in their eyes, as if it could devour everything around them.

Then, they moved, left the core of the earth, appeared on the ground like ghosts, and then ran rapidly towards the direction where the demons gathered.

In an instant, seven blood-red shadows streaked across the sky like meteors and quickly disappeared into the distance.

The demons who were arguing heatedly suddenly stopped all their movements as if they were cast under a spell. They all looked up and cast their gazes towards the distant sky.

A few minutes later, seven figures emitting an ancient and powerful aura swept towards this side like a violent storm.

Those star cluster-level demons were startled and instinctively wanted to escape.

But they clearly felt that the aura emitted by the seven figures was like an icy shackle that locked them tightly, making them shiver all over, and for a moment they did not dare to make any rash moves.

In the blink of an eye, seven figures landed steadily in front of them.

The Primal Gluttony Demon raised his lips with an evil smile and said slowly, "Wow, it's really lively here. I have to join in the fun."

Before he finished speaking, he waved his hand, and the several demon sons next to him were pulled by an invisible force and flew into his hand involuntarily, and then he swallowed them up without mercy.

At this moment, the demons present seemed to be gripped by fear, and no one dared to move an inch.

They all opened their eyes wide, looking at the seven terrifying figures that seemed to come from the deepest part of hell in disbelief.

The Primal Arrogant Demon glanced coldly at the surrounding demons and said loudly, "Everyone, stop arguing. The masters of this Hell plane belong to none other than the seven of us."

"But this time, the situation is different. We will not divide the territory. Instead, we will unite to expand outward, especially to the plane of the gods. We will make them pay a heavy price for their past actions."

As he spoke, he turned to look at the other six original demons. Seeing that they all agreed, he continued, "From today on, we will fully prepare for war."

"Let the little demons fight each other to increase their strength. Don't worry about not having enough little demons. We have just reached an agreement with the plane core. Our goal is to attack the Gods' Plane!"

The demons looked at each other in silence, not knowing how to respond.

Seeing this, the primal furious demon's eyes blazed with fire, and he shouted at the group of demons, "What? Are you all mute? Do you want me to help you open your mouths?"

The demons were frightened by the roar, and then they spoke reluctantly, expressing their agreement.

At this time, the Primal Greed Demon stepped forward and said sternly, "You have one week to build the Palace of the Seven Deadly Sins from ancient times. Here are the blueprints."

After saying that, he waved his hand and a pile of drawings were thrown out, scattered in front of the demons.

The demons looked at the drawings on the ground, looking at each other, and no one showed any intention of picking them up.

Just as the original greedy demon was about to erupt in anger, Mephisto stood up and reached out to put the blueprint into the space ring.

The Primal Greed Demon glanced at Mephisto and announced, "Mephisto, from now on, you are the person in charge of building the Palace of the Seven Ancient Sins. During this period, everyone must obey him, otherwise..."

Hearing this, the demons cursed in their hearts, and at the same time regretted why they were a step slower.

Seeing that everything was almost arranged, the original seven deadly sins demons prepared to leave.

At this time, the primal lust demon Lilistra stopped and warned, "The environment here has improved now, so don't destroy it at will."

After saying that, she turned around and left with the other primordial demons, leaving only the demon gods standing there with different expressions.

After a while, Mephitos deliberately cleared his throat and stood in front of everyone with a serious expression.

"Everyone, listen up!"

At the same time, he waved his hands in the air, trying to attract the attention of all demons and devil's children.

"Let's start dividing the work now and work hard to build the ancient palace of the seven deadly sins. Everyone must obey my command!"

Murphystos paused, glanced at everyone, and continued, "First, we need to dig out the underground Nether Frost Stone from the Far North Abyss. This is the main material for building the palace."

"There's no time to lose, everyone, act now, quickly! If anyone dares to slack off or disobey orders, don't blame me for being rude and reporting directly to the Seven Deadly Sins!"

The other demons and sons of the devil all turned their eyes to Mephisto, their eyes full of resentment. If their eyes could turn into sharp blades, Mephisto would have been cut into pieces long ago.

But under the threat of the original seven deadly sins, although they were dissatisfied, they could only grit their teeth and reluctantly prepare to carry out the mission according to Mephisto's orders.
