"So this is... the level of a giant beast!"
Lu Sheng's eyes narrowed slightly, feeling the changes within his body.
Although the fourth tier was nothing notable to Lu Sheng's true body, breaking through to the fourth tier from a lizard form was still quite wondrous.
It made Lu Sheng unable to resist experiencing it thoroughly.
But after feeling it carefully, a faint glow appeared in Lu Sheng's eyes.
"This is..."
Lu Sheng's mind gently moved, and a special energy surged out from his body, similar to the domain of the mental realm he had previously understood in the Human Federation.
It actually directly created something akin to an energy domain around his physique.
"This energy... it is very similar to the domain of mental realm, and vaguely carries cosmic dao waves."
"Could it be... this special domain is the manifestation of Beast Realm creatures' insights into the cosmic dao?"
Lu Sheng thought with interest.
