The middle-aged gunman saw the Purple Heart Grass and his eyes lit up, "The beam of malevolent energy condensed in ordinary Purple Heart Grass is only thumb-sized. The beam in this Purple Heart Grass is actually so large."
This is the Purple Heart Grass...
Luo Feng had heard of this spirit plant, capable of absorbing the world's malevolent energy and condensing it. It is quite beneficial for martial artists who practice vicious techniques.
The quality of the Purple Heart Grass is generally distinguished by the size of the malevolent energy beam in the middle of the plant. The larger the beam, the higher the quality. A walnut-sized beam is already very rare, let alone fist-sized.
