ASFUCITWON Chapter 146: How It Works and Side Effects

When this seal is activated, a complex Fuinjutsu pattern begins to form on the target's body, glowing with a golden light that flickers like sunlight filtering through the gaps in leaves.

These symbols rotate with an almost impossible precision, interlinking and forming a complicated network, as if rearranging the target's fate.

In a matter of seconds, the pattern adheres to every part of the target's skin, spreading like ink poured onto a canvas.

A faint heat begins to creep in, followed by a tingling sensation that pierces deep into the flesh.

But that is just the beginning.

As the seal starts to fully activate, the energy stored within it explodes throughout the body, striking the main Chakra points with tremendous force.

Every chakra point touched by this energy vibrates, opening hidden pathways within the body, stimulating the flow of Chakra and Natural Energy into the metabolism and regenerative system.

It feels like a wave of hot water sweeping through the body’s tissues, eroding layers of old cells that have weakened over the years, then replacing them with fresh new tissue.

Within the body, changes occur in ways that cannot be seen with the naked eye.

Beneath the surface of the skin, billions of cells begin to replicate at an impossible speed.

Dead cells are destroyed without a trace, while new cells are born in perfect condition.

Bones that had weakened from years of supporting a weary body now harden again, reinforcing their structure as if time has been turned back.

Muscle tissue that had lost elasticity now tightens again, providing a sensation of strength long forgotten.

The heart beats more steadily and powerfully, pumping fresh blood throughout the body with balanced pressure, bringing warmth and newfound vitality.

Physically, these changes are striking.

Skin that was once lined with fine wrinkles now appears smooth as silk, as if untouched by age.

Hair that had faded or lost its original color gradually returns to its natural hue, strand by strand, until it finally forms a shiny mane reminiscent of youth.

Eyes that had dimmed slightly under the weight of time now shine again, pupils becoming sharp as if filled with a newly discovered zest for life.

Muscles that had slackened are now taut again, the posture that was once hunched or slightly slumped now stands perfectly upright, as if the target has just been reborn.

However, behind this miracle lies a price that must be paid.

For those who do not have a sufficiently large reserve of Chakra, this seal demands Life Energy in return.

Life Energy is the essence that determines how long a person can live—something that cannot be easily regained.

In Reiji's case, who has limited Chakra, this seal demands a sacrifice of fifty years of Reiji's lifespan to remain stable.

This sacrifice does not immediately cause aging, but quietly erodes Reiji's remaining time in the world.

If previously Reiji could live up to a hundred years, now his limit is only half of that.

This means that when Reiji reaches the age of fifty, his body will run out of Life Energy, leading to an inevitable death.

Even so, Reiji is undaunted.

He has methods to restore his lifespan, extending his life in ways that only he understands.

However, even though this 'Fuinjutsu: Age Reversal Seal' appears to be a blessing, using it more than once in a lifetime can lead to disaster.

Forced cellular regeneration too frequently will cause genetic instability, making the body lose the ability to regulate cell growth.

If this limit is exceeded, cells will continue to replicate endlessly, leading to mutations that cannot be stopped.
