As the spiritual liquid inside the Jing Yu bottle slowly poured out, the Fu Ling grass within several miles benefitted.
They grew vigorously, forming a massive wave of grass that rustled and whose sound traveled far into the distance.
The demon turtle sensed unease and let out another low growl.
But this growl, masked by the sound of the grass wave, went unheard by Lu Chen.
His vision had improved due to the Hateful Heaven Pupil Technique, but there had been no change in his hearing.
Of course, had Lu Chen cultivated the Heart's Eye, that would be a different story.
At the moment, he was fully focused on the spiritual liquid inside the Jing Yu bottle.
Since there wasn't much liquid left, it would now empty even faster.
But the demon turtle clearly couldn't wait much longer; after hesitating on the spot for some time, it still decided to come and investigate!
It did not know who had caused its unrest.
