As we all know, the Pure Fire is used on He Island to eliminate filth. Those twisted and ugly monsters cannot be killed by normal means, and will continue to erode the surroundings, causing permanent pollution.

Therefore, the original priestess of the Waseda Taisha Shrine sacrificed herself and turned into a huge sacred cherry, and established a mechanism for the main priestess to control the pure fire, using these never-extinguished flames to destroy filth.

Of course, pure fire is a stronger form of pollution. Using pure fire is just a temporary solution to a problem and can only delay the arrival of doomsday.

Lu Ban was curious about how the Pure Fire was constructed and how the Brilliant Realm controlled the Pure Fire.

The Pure Fire that he exchanged from [Silent Department Store] was placed in a bottle. The bottle was obviously not affected by the Pure Fire. And from Lu Ban's current observation, the Brilliant Realm did not seem to be burned or eroded by the Pure Fire. After experiencing tens of billions of years, if the Brilliant Realm did not have the means to control that thing, it would be impossible for it to survive.

And if they could find a way to control the Pure Fire, then at least the island would be saved.

The walls around him were glowing, and Lu Ban soon found himself high in the air.

He knew that this was the effect of knowledge pouring into his brain.

Through the study of the previous room, Lu Ban roughly figured out the use of this place, especially the knowledge that recorded the beginning and end of the entire alien civilization, which was not as simple as just watching from a distance.

Lu Ban's will flowed, and the earth suddenly approached him. In a blink of an eye, he stood on the ground.

This is a barren land. The surface is cracked due to lack of water. The surface is covered with high temperatures that are unbearable for ordinary people. There is a choking and unpleasant smell in the air, just like the earth before life appeared.

However, Lu Ban saw a towering building. It was a tower. The tower was taller than the highest mountain on earth. It stood on the ground, alone, as if abandoned by the world.

Lu Ban's mind moved, and he immediately moved to the bottom of the tower.

Looking up, he saw the top of the tower, burning with pale flames.

It was not pure fire, but it was somewhat different from pure fire. At least in terms of the degree of pollution, Lu Ban believed that this pale flame was far inferior to pure fire.

He walked into the tower and immediately saw a giant.

The giant was about three stories tall, with slender hands and feet, but a bloated body. His body was dirty and stained with orange blood. The giant was dragging a cart with the giant's broken limbs and remains on it.

The giant seemed to have completely ignored Lu Ban and walked straight past Lu Ban and out of the tower.

There were still many dead bodies in the tower.

These corpses looked like they had been through a battle, scattered all over the place, most of them were like the giant.

Lu Ban looked up, and in an instant, he arrived at the top of the tower.

Lu Ban saw that the fuel in this place where the pale flames were burning was corpses.

"We are running out of time."

A voice sounded, and Lu Ban looked behind him. It was a giant wearing a robe with gemstones decorating his body. Those stones were deeply embedded in his skin, and it was painful just to look at them.

From Lu Ban's perspective, the giant looked quite handsome. He had a melancholy look in his eyes as he looked at the pale flames.

"The fire is about to go out, and the king is nowhere to be seen."

On the other side, an old giant said quietly.

The old man looked into the distance.

Lu Ban followed his gaze and saw the same tall tower.

However, the flame burning on the tall tower was dimmer and weaker than the one here, and it seemed like it was about to go out.

"The fire in the north is almost out, and the fire here won't last much longer. When all the fires are out, will our world really come to an end?"

The handsome giant said worriedly.

"The city in the west no longer exists. The spreading evil has swallowed everything. Without fire, we have no way to resist those monsters."

Listening to the conversation between the two people, flashing fluorescent words appeared in Lu Ban's vision.

These texts recorded the conditions of this foreign land and flowed into Lu Ban's mind in the form of knowledge.

According to the naming of scholars in the Glorious Realm, this foreign land is called ESFD-36955. It is a world still in the stage of agricultural civilization. However, the Old Ones sealed here fell into a semi-awakened state due to some accidents. Therefore, the pollution of the Old Ones leaked out and affected the creatures on the planet. Many animals were alienated and became the followers of the great gods.

These followers are very aggressive and try to assimilate other creatures, just like the demonic tide of the Kingdom of Darkness.

Only fire can resist the invasion of these monsters.

These flames are called Ash Fires, and they can only last by burning the corpses of giants. Wherever the light of the Ash Fire shines, the power of the followers of the Old Ones will be weakened exponentially. It is only with the illumination of these flames that this foreign land has been able to survive until now.

But even so, the world has come to an end.

The giants' reproduction rate is not fast, and the monsters covered by the gray fire do not become weaklings who are powerless. Even in the form of wild beasts, they are strong enough to cause casualties to the giants.

There is always a limit to burning corpses, and that only slows down the pace of world destruction.

Just like this tower, there are less than ten giants left alive.

Lu Ban can freely descend to any time period and any location in this foreign land, just like really descending into this world, reading materials while experiencing their lives firsthand.

He adjusted the time backwards and came to the time when the last ball of gray fire was about to go out.

On the high tower, Lu Ban saw this handsome giant, and beneath him were the corpses of countless his companions.

The pale flame illuminates the world, it is the only light left here.

Looking at the entire planet, it is already filled with the followers of the Old Ones. They are digging deep into the surface, trying to find their masters. At the same time, the only light in this dark world is also in danger.

The corpses of the giants were burning, but the last of the giants already knew that their civilization was destroyed.

Sadness, despair, pain, confusion, all emotions flooded my heart.

A kind of pollution burst out from his heart.

Those were whispers that had been repeated countless times, whispers from the Old Ones.

At this point, this last giant no longer had anything to pursue.

Except hatred.

Hatred quickly took over all his will, and even the whispers of the Old Ones could not shake him.

He looked at the monsters rushing towards him, turned around, and threw himself into the pale flames.

In an instant, the pale flame, which had originally dimmed and faded, suddenly turned black.

In that pure black flame, colorful emotions took shape.

In an instant, all the corpses were burning with the same flame.

The flames engulfed giants, monsters, planets, and even the Old Ones were twisted in the flames.

In the end, only a silently burning planet remained in the cold and lonely universe.

Lu Ban saw that after the planet had been burning for tens of thousands of years, the scholars of the Brilliant Realm finally ended their observation and headed here.

They discovered that this flame could burn everything, even in a place where there was nothing, and it could continue to burn everything.

Except for some things.

Except for the skeletons left by the giants.

The Glorious Realm used the skeletons of giants to create containers and carried these flames to some foreign lands that were used as laboratories.

This is the pure fire.
