Mankind's most advanced deep submersible, the "Abyss", challenged the 10,000-meter abyss of the Mariana Trench, and unexpectedly encountered an existence that subverted cognition - a living "dragon". This behemoth, recorded by the ancients as "eating clouds and thunder, sheltering from fire", is a miracle of deep-sea evolution: it rides upwellings like the wind, and the hydrogen in its body drives it to soar and hunt, and it can even rush out of the sea to swallow storms and lightning to replenish energy. However, its majestic vitality is accompanied by a fatal taboo - fire.
The Abyss's artificial flames accidentally ignited Taboo, causing a violent explosion that seriously injured the dragon. The scientific expedition team members traced its scattered burning scales, went deep into dangerous situations, and finally arrived at the burial place of the giant beast with the icy warning "Dragon Tomb - Fire devours its soul, and the abyss buries its bones." The "dragon blood" samples brought back revealed the secrets of extraordinary biological materials and energy mechanisms, instantly igniting global greed, especially attracting the covetous attention of the business giant NAT.
Doubts, political undercurrents and armed looting ensued. NAT's sonic weapon forced the dying dragon into a desperate situation, triggering a tragic guardianship battle in the 10,000-meter abyss. The giant dragon used its own leaked hydrogen as a weapon and launched a shocking self-destructive counterattack. It was seriously injured and struggled to return to the depths of the Dragon Tomb.
In order to save themselves, scientists ventured deep into the heart of Dragon Tomb and discovered the amazing wisdom of dragons coexisting with extreme hydrothermal ecosystems. They used their symbiotic organism "Blue Light Doctor" to launch a life-saving plan code-named "Fluorescence". A faint dragon's roar sounded in the abyss, symbolizing the hope of rekindling life, and also announcing that a long dialogue and protection based on awe between humans and the guardian of the abyss had just begun.
