Within the spacetime.
Lin Chuan slowly opened his eyes. The Nine-Tomoe Sharingan radiated a cold, sinister pressure, causing the entire space to abruptly freeze.
The Enlightenment Ancient Tree behind Lin Chuan swayed gently. Its emerald glow had dimmed considerably, and some of its branches had even begun to yellow and wither. Its aura was no longer as powerful as before.
Lin Chuan glanced back and felt that the Enlightenment Ancient Tree seemed to be looking at him resentfully.
"Ah... sorry, I didn't notice..." Lin Chuan restrained his aura and spoke awkwardly to the Enlightenment Ancient Tree.
Whenever Lin Chuan had borrowed the Enlightenment Ancient Tree's aura in the past, he had always exercised restraint and never overdone it. After all, this Enlightenment Ancient Tree had only been growing for a few years. Though its trunk was enormous, it was, comparatively speaking, little more than a fresh sprout. The enlightenment aura it could emit was limited, and absorbing too much would greatly affect its growth.
After entering seclusion this time, Lin Chuan had not paid attention to the Enlightenment Ancient Tree's condition, causing him to absorb far too much enlightenment aura without restraint.
By now, Lin Chuan had sucked the Enlightenment Ancient Tree into malnutrition. It looked sickly and frail, truly hollowed out.
"Alright, don't worry. I won't treat you badly!" Lin Chuan said with a smile, stroking a drooping branch of the Enlightenment Ancient Tree.
After all, it was an existence ranked among the top ten of the Heaven and Earth Chronicle. Though it had not been born long ago, it already possessed considerable intelligence and could communicate with Lin Chuan in simple ways.
The immense immortal chakra in his dantian rapidly circulated before erupting outward. Under Lin Chuan's control, it flowed into the roots of the Enlightenment Ancient Tree.
