Overview of the Subtle World – The Nano Divine Realm Era
The Subtle World is a futuristic era tens of thousands of years after humanity left the Solar System and established a glorious civilization spanning thousands of planets, collectively known as the Heavenly Star Federation.
The Federation is divided into multiple planetary alliances, among which the Zhonghua Federation controls the largest number of planets and possesses vast, limitless resources. Because of this, many other factions and federations seek to invade and destroy it.
This civilization has long abandoned conventional physical weapons and evolved to its peak through Nano Core Arts – a fusion of nano-particle technology and neural bio-engineering.
Nano Cores: The Heart of the World
At the age of 3, every individual undergoes a physical and neural compatibility test to activate a Nano Core, a microscopic biological system embedded within their body.
Nano Cores allow humans to:
Enhance physical strength, reflexes, and intelligence.
Transform into mechanical armor and manifest combat weapons at will.
Connect to medical systems instantly, heal cells, transplant organs, and even restore damaged nerves.
In battle, Nano Cores can unleash crystallized abilities called Myriad Techniques.

Ranks – Divine Martial Body Arts
Powerful beings in the Subtle World are ranked according to their mastery of Divine Martial Body Arts, from lowest to highest:
Grade E – Primal Awakening: Basic level, just activated Nano Core.
Grade D – Soul Forging: Can use nano for combat.
Grade C – Star Domain: Short-distance flight, able to sense living energy nearby.
Grade B – Divine Light: Learns special techniques, can control Nano Mechs (no one under 15 can reach this level—except our two main characters).
Grade A – Phantom Violet: Stable martial body, capable of leading small squads.
Grade S – Emperor Realm: Incredibly powerful; those below this level are like ants.
Grade SS – King Form: Planetary leaders with authority to declare war.
Grade SSS – Divine Source: On the brink of godhood, though not truly gods.
Grade SSSS – Divine Realm: Legendary level, considered actual gods in myths.
(Note: Our Vũ Gia Hoàng has only touched the SSS level, and even then, he hasn't fully grasped it.)

Nano Mechs – The Soul Beyond the Body
In the Subtle World, mechas are no longer bulky machines but a fusion of human consciousness and reactive nano-tech, known as Neural Mechs. When summoned, the mech envelops the user's body, transforming based on the user's spirit. Some high-tier mechs even possess independent consciousness—called Mech Souls.
They are also ranked from Grade E to Grade SSSS.
(To summarize: in the story, I'll explain mechs later since they're pretty much like body arts. I'm just too lazy to write more now. Hope you all support this!)
