China, within a secret laboratory:
Long Xingkui and Qinghuang stood beneath a cracked glass wall, which had shattered into countless tiny fragments but showed no signs of breaking due to the special material of the glass.
However, Qinghuang looked at this glass wall, her face unable to hide her shock.
"This is the power of the strongest Sentinel…"
She had always been focused on the Sentinels cultivated by the Long Family.
The Sentinel project was developed by Chu Huang, who created Sentinels for the Long Family only to be later eliminated by them.
Later, Chu Huang returned to the Floating Island and, using her astounding memory, wrote down the complete Sentinel research.
The detailed Sentinel research was divided into two parts, with the lower part kept by Qinghuang. Only recently had Qinghuang learned that the upper part of the Sentinel research had fallen into Shen Manli's hands.
