The Sword Spine touched his hand gently, yet cautiously. Then, it retracted. It seemed like a mischievous child who had just got a shock, and hadn't been able to regain his composure.
Chu Yang finally laughed.
The Sword Spine relaxed as it saw him laugh. It hurriedly made its way back. It merged with the other two fragments, and congealed a sword. The sword then issued a joyful sword-cry.
The entire blade of the sword was covered in a layer of gentle white-light. It seemed as if a layer of silver mercury was flowing on the sword's blade. Suddenly, the blade issued a trace of a pinkish-bloody light. It flashed for an instant, and then disappeared.
The sword's blade went silent.
Chu Yang realized that the three sword fragments had integrated. Moreover, they had surrendered to him.
"You must be obedient if you wish for me to use you.
"I will abandon you if you're not."
This was Chu Yang's principle.
