Only Sense Online - Volume 8, Chapter 3 - The Expedition and Volcanic Area

Until he became the lowest-ranked master, his lonely and luckless life never changed.

Suddenly one day, a descendant injected him with a nanomachine, and the machine started ‘speaking’ to him.

“What? What are you talking about?”

This was beyond the boy’s knowledge, he turned pale.

The Nanomachine linked to his cerebrum realized the User was not understanding a single word it said.

“Who are you, and why are you doing this to me?”

“Nano Mashin?”

The boy’s face hardened.

Mashin was the deity the Mashin Religion worshipped, along with the Sacred Fire.

The religions’ Master communicated with Mashin.

“Um, are you really Mashin?”

The boy knelt down and asked with a trembling voice. At this, the Nanomachine attached to his cerebrum realized it had been misunderstood.

In a realm where power is determined by affinities—elemental forces that shape magic, combat, and survival—Ethan is an anomaly. While most people are born with a single affinity, Ethan stands apart, wielding a vast range of abilities granted by a mysterious Ancestral-line System. This unique system taps into the untapped potential of his vampire and dwarven bloodline, unlocking ancestral powers far beyond the norm.At just 18 years old, Ethan's journey begins when he accidentally awakens this system, discovering that he is the heir to a forgotten lineage that blends the strength, resilience, and mysticism of both vampire and dwarven ancestors, a perfect hybrid of both. Though he must awaken and evolve to harness their power. However, the more power he gains, the more he learns about the dark secrets of his lineage—secrets that others would kill to possess.Unlike everyone else, Ethan's affinities are not innate; they are granted by the system based on his bloodline’s ancient heritage. As he levels up, he acquires abilities that no one in the current era has ever seen: the Psychic powers of telekinesis and telepathy from ancient vampire lords, the earth-shaping skills of dwarf warriors, and a host of hidden abilities that challenge the world’s very understanding of magic.But power comes with a price. Ethan quickly finds himself targeted by powerful factions and hidden enemies who fear what his bloodline could mean for the balance of the world. Ancient forces tied to his ancestry awaken, each with their own agenda—some seeing him as a threat to be eliminated, others as a tool to be used.Accompanied by a diverse group of companions, each with their own affinities and secrets, Ethan embarks on a perilous journey. Together, they traverse beast-filled forests, ancient ruins, worlds and perilous dungeons, all while facing foes who seek to exploit or destroy Ethan’s unique powers. Along the way, bonds are forged, fates are entwined, and the line between friend and foe blurs as Ethan learns that his destiny is far greater than he ever imagined.But with every new ability comes a deeper question: What is the true purpose of the Ancestral-line System? As he battles monstrous creatures, rival affinity users, and ancient curses, Ethan must confront the reality that his bloodline holds the key to either the salvation or the destruction of their world or something else entirely.In a world governed by affinities, Ethan’s unmatched power sets him on a path that could change everything—or lead to his downfall.Will he master the secrets of his ancestry and forge his own fate, or will the weight of his heritage drag him into the depths of a history best left forgotten?
