Su Yi fell silent for a moment, then said, "To judge the length of the road, one must cast one's gaze far ahead. From now on, I'll use you as a sharpening stone to temper my state of mind."
Before the First Lifetime Heart Demon could speak again, Su Yi had already put away the Rotten Sword Sheath and sealed it with the power of the Nine Hells Sword.
Only in this way could he completely cut off the other party's senses.
In the future, I should also use this sheath as little as possible.
Su Yi knew very well that each time he used the sword sheath, his dependence on the First Lifetime Heart Demon would deepen by another measure.
Most dangerously, the First Lifetime Heart Demon could devour all kinds of power during battle to strengthen himself.
If this continued, the other party was destined to become increasingly dangerous, and sooner or later would cause a grave problem.
Just like how the First Lifetime Heart Demon had suddenly taken the initiative to ask for the Chaos Profound Stone this time, it definitely had not been a casual remark.
It was very likely that the power of the Chaos Profound Stone was precisely what he craved!
"brother Su."
In the distance, Feng Wuji walked over.
Rahu Demon Ancestor followed at his side.
However, the old fellow had his head hanging low, looking awkward and ill at ease.
Yet, when he neared Su Yi, Rahu Demon Ancestor sighed, bowed deeply, and performed a long formal salute. "No matter how brother Li intends to treat me next, I must thank you for saving my life this time!"
Brother Li.
Subconsciously, he was still treating Su Yi as the Li Fuyou of old.
Su Yi looked Rahu Demon Ancestor up and down.
