Feng Qi stared at the analysis on Rune Modifiers displayed on the large screen before him, lost in thought.
His earliest knowledge of Rune Modifiers had come from Old Wang's history class.
When the Rune Modifier Project was first born, humanity's exploration of Cultivation Studies was still in its infancy. People had only just proposed the idea of drawing the spiritual energy that filled heaven and earth into the human body.
During the dissection and study of Domain Creatures' physical structures, researchers discovered that the Rune Crystals embedded within their bodies contained immense power.
Someone then proposed a hypothesis: if Rune Crystals could be embedded into human bodies, could humans also gain terrifying strength comparable to Domain Creatures?
Thus, the Rune Modifier Project was officially established.
At the time, this school of research overshadowed Cultivation Studies and became society's mainstream research direction.
But its drawbacks soon became apparent.
Those humans implanted with Rune Crystals did indeed gain powerful strength in a short period of time. They could even rely on the Rune Crystals to absorb the spiritual energy of heaven and earth and strengthen themselves.
But Rune Crystals ultimately came from different Domain species and could not perfectly integrate with the human body.
The first batch of test subjects gradually developed rejection reactions. Some even suffered mental breakdowns and drastic personality changes, gradually becoming uncontrollable and creating serious safety hazards.
