A few years ago, people from Beta Perseus came to Earth for investigation and left behind the "Dragon Spine", a device that perfectly combines biology and machinery.
After all the changes, the Dragon's Backbone was buried deep underground somewhere in China. The only thing that can prove its existence is a biochemical crystal "KEY" that hides its genetic sequence. After years of research, scientific researcher Song Tao found it by detecting the fluctuation signals sent by "KEY" and planned to study the dragon's spine in depth.
However, the good times did not last long, and the fluctuations sent by "KEY" became more and more intense. A strong signal caused some official or private research institutes and underworld groups to discover the secret of Dragon's Back one after another, and wanted to take the research results of "KEY" and Song Tao as their own. An underground organization attacked Song Tao's laboratory and residence and took away all his research materials. Before dying, Song Tao implanted the "KEY" that he protected with his life into the body of his only daughter who was lucky enough to escape.
Song Tao's wife changed her daughter's name and settled in a distant place, temporarily avoiding the storm. But ten years later, "KEY" once again sent a strong signal. After losing her parents, the "KEY" host girl known as "Dragon Lady" is in crisis again... Carrying a heavy fate, fulfilling her father's last wish and avenging her parents, how should she implement her own truth?
Jian, you need to know.
Your loved ones will not be able to protect you.
Best friends will betray you.
The person who saves your life may be someone with whom you have a grudge.
You will be loved, hurt, and used, and finally you will understand——
There is no absolute truth in this world, so please believe in your own truth.
Then you will see the light ahead.
