"Forget it. I'll improve the deduction first."
Lu Sheng gathered his thoughts and began focusing on improving himself.
With a thought, the Modifier interface trembled slightly. He pressed the modify button and entered modifiable mode.
"Raise the Mystic Origin Heart Sutra to the fourth layer!!"
The instant the command was issued, the entire Modifier panel rapidly blurred.
Centered on Lu Sheng, vast amounts of spiritual energy from the surrounding earth surged wildly toward him.
Fortunately, the spiritual energy density of the Primordial World far exceeded that of every world Lu Sheng had stayed in before. Even underground, it was dozens of times richer than the spiritual-energy worlds he had previously inhabited.
The immense, viscous spiritual energy filled Lu Sheng's entire body in a few breaths.
A great deal of spiritual energy was converted and consumed, used to enhance Lu Sheng's physical resistance, strength, recovery ability, and charisma.
Soon, the influx of spiritual energy stopped, and Lu Sheng slowly sensed the condition of his entire body.
A round, pale-purple golden core had appeared within his chest and abdomen, continuously rotating. The golden core ceaselessly transformed external spiritual energy into Lu Sheng's unique dark-red Demon Power, which flowed through the blood vessels of his entire body.
Yet as the Demon Power continued to transform, Lu Sheng vaguely saw a faint trace of gold amid the red Demon Power.
This body has entered the Golden Core stage. It seems a trace of the original body's Old Gu bloodline has been developed again.
Lu Sheng carefully experienced that faint golden trace. Hidden within it were concepts of nobility, scorching heat, light, rebirth, and more.
From afar, it was like looking at a landscape painting; somehow, one could sense what it contained.
"This should be the Vermilion Bird Bloodline Lan Xi and En Ruo mentioned."
