The weakest martial artist? One punch and he's leveled up a whole realm!

Top floor of the library.

The old administrator began restoring some ancient books.

Ye Xiao sat by the window, from where he could see the bustling students coming and going outside the library's main entrance.

He withdrew his gaze and stared again at the book in front of him, "Introduction to Boundary Marks and Their Distribution".

The book was thick, the paper was yellowed and brittle, and there were traces of insect damage on the edges.

He flipped it very slowly, afraid of tearing it.

This book has nothing to do with cultivation; it is a miscellaneous record that documents what extraordinary individuals throughout history have seen and heard in different realms.

Boundary marks are not innate.

Ten thousand years ago, the spiritual energy of heaven and earth was restored, and humans and all other races coexisted on the same continent.

Later, a great war tore the world apart—not a war between humans and demons, but a split in the "Tao".

The world is divided into two: the human world and the monster world.

Between the two worlds lies only a "boundary line".

A boundary mark is not a crack.

It is a "membrane" between two worlds.

Like a scar on the skin, like a crack in porcelain, like the wall between two rooms.

A crack is a hole in the wall.

Ninety-five thousand years ago, the thinnest part of the boundary cracked.

Monsters have entered the human world for the first time.

That war lasted for a thousand years, and humanity was almost wiped out.

It was the nameless patriarch who punched through the demon world and then sealed the boundary with his fist intent.

The seal is now weakening.

Ye Xiao paused at this point and looked out the window.

The setting sun dyed the sky a dark red, like blood.

The boundary has 88 weak points, distributed around the world.

These weak points are the "root" of the crack.

Monsters cannot directly attack the seal, but they can erode it with demonic energy.

Just like water dripping on a stone, or an iron pestle being ground into a needle.

Ninety thousand years is enough to erase many things.

How long can the seal last? It's not written in the book.

But Ye Xiao noticed that there was a line of pencil annotation next to this paragraph, the handwriting was very fresh, as if it was written recently.

"It will take at least three years, and at most five years."

His hands began to tremble.

Are you scared?

Before he knew it, the old administrator was already standing behind him.

At the same time, a cup of mellow new tea was placed on the table in front of Ye Xiao.

"Have some tea before you read on."

Ye Xiao remained silent, then raised his head and looked at the old administrator.

"Professor Qian, did you write this annotation?"

The other party did not deny it.

"Yes."

Ye Xiao took a deep breath: "Will the boundary mark break in as little as three years?"

The other party nodded.

"This is the worst-case scenario."

"You already know the secret that cannot be revealed."

Ye Xiao asked, "Why can't I say?"

The other party said, "Once this secret gets out, the world will be in chaos. Human nature cannot withstand the test. Once people know that the end of the world is coming, social order will collapse instantly, and people will fall into a final madness before the end of the world, indulging in their desires and committing crimes to their heart's content."

Upon hearing this, Ye Xiao remained silent for a long time.

The old caretaker smiled and comforted him, "These are not things you should be thinking about right now."

"If the sky falls, the tall ones will hold it up."

"There are so many extraordinary individuals up there; they want to live more than anyone else."

Upon hearing this, Ye Xiao smiled with relief.

"Mr. Qian, you're right."

"Even if the sky falls, there are tall people to hold it up."

Ye Xiao continued reading the book.

soon.

He saw content related to [Red Abyss].

That's what he wanted to know.

"The Crimson Abyss, the seventeenth of the eighty-eight rifts, is located in Jiang City. Its seal is weak, monsters are active, and it is highly dangerous."

A simple comment was enough to depict the danger of Chi Yuan for Ye Xiao.

"The world beyond the rift is a sea of ​​fire. Land is scarce, and there is endless lava. Lava rivers crisscross the land, and volcanoes erupt every few minutes. The air is filled with the smell of sulfur and coke, and the temperature is so high that steel melts and rocks turn red."

"The sky is dark red, and the sun is never seen. Only the light emitted by the lava dyes the whole world the color of hell."

"Deep within the Crimson Abyss lies a volcano. Its crater is a thousand feet in diameter and its depth is unfathomable. Lava gushes from the crater, forming rivers that flow into the distance. That volcano is the lair of the Flame Demon King."

Ye Xiao's throat tightened.

He imagined that world—without wind, without rain, without sound.

There were only the gurgling of lava, the roar of volcanoes, and the howls of monsters.

"The monsters of the Crimson Abyss are mainly fire demons. Fire demons are not creatures corrupted by demonic energy; they are the embodiment of demonic energy itself—fire, magma, and sulfur. Their bodies are made of fire, making them almost immune to physical attacks."

"Flame Demons are divided into four ranks."

"The lowest level is the Balrog larva, about one meter tall, with charred skin, capable of breathing fireballs, and reaching temperatures of up to a thousand degrees. It is equivalent to the second realm of humans. This type of monster is the most numerous, swarming in groups, like locusts covering the sky."

"The medium-sized ones are Flame Demon Warriors, about three meters tall, with flame patterns all over their bodies. They can transform into flames and are immune to physical attacks. They are equivalent to the fourth realm of humans. They wield battle axes made of solidified magma, capable of cutting through steel with a single blow."

"The highest level is the Balrog Lord, which is about five meters tall and has fiery wings on its back, allowing it to fly. It can summon magma and incinerate everything. It is equivalent to the seventh realm of humans. Each Balrog Lord rules over a magma territory."

"The highest level is the Flame Demon King, about ten meters tall, slumbering deep within the volcano. With a single thought, it can ignite an entire city; with a single rage, it can melt down a mountain range. It is equivalent to the tenth realm or higher among humans."

Ye Xiao put down the book and closed his eyes.

A ten-meter-tall fire giant appeared in my mind, standing at the crater of a volcano, looking down on the human world.

He opened his eyes and continued looking down.

"The dangers of the Crimson Abyss are not limited to demons."

"First, the high temperature. The magma in the Crimson Abyss reaches a temperature of three thousand degrees, and any creature that falls in will melt instantly. Even a martial artist with a golden body can only last a few breaths at the edge of the magma."

"Secondly, poison gas. The air in Crimson Abyss is filled with sulfur and sulfur dioxide, which will burn the lungs and corrode spiritual energy if inhaled. An ordinary person would die from poisoning within minutes of entering."

"Third, the space is unstable. The space around the cracks in the Crimson Abyss is severely distorted. If you are not careful, you will be swept into the void turbulence and be lost forever."

"In addition, there is another special danger in the Crimson Abyss—the will of the Flame Demon King."

"The mental fluctuations it emits while dormant can erode one's mind. Staying in the Crimson Abyss for too long will make people irritable, easily angered, and irrational. In severe cases, they will be directly controlled by the Flame Demon King and turned into half-human, half-demon monsters."

Ye Xiao's hand stopped on the page.

Here, he saw a line of annotations next to it.

"If you stay in the Crimson Abyss long enough, you will hear a voice. It is calling you, calling your name."

Danger lurks everywhere in the Crimson Abyss.

"But the Crimson Abyss also has its opportunities."

"First, there is a mineral deep within the magma called the Heart of Molten Fire. It is a crystal formed from the energy that condensed when the Fire Demon King slept, containing extremely pure fire laws. After refining it, it can grant the physical body fire resistance and even greatly enhance the power of fire-type skills."

"Secondly, on the edge of the Crimson Abyss crater, there grows a plant called Fire Spirit Grass. It is the only spiritual plant that can survive near lava and is the main ingredient for refining high-level fire-type pills. A single Fire Spirit Grass can sell for hundreds of thousands on the black market."
