Fan Fan

She appeared as China's leading bioengineer and member of the Academy of Science in order to study Xia Lei's body and determine how he is resistant to 'Alloy X'. Xia Lei, wishing to avoid exposing his secrets at all cost, seduces her and gets her to change the results of her experiments.

Later, Ling Han collaborates with Ye Kun, Mu Jianfeng and Yu Shanhe to try and merge Thunder Horse Manufacturing with China Industrial Group and Hanwu Weapons in order to get Xia Lei's business under state control and exclude him from management. A mysterious woman named Su Xiao, an agent of ZN Bureau, then threatens to reveal Xia Lei's test result and his IQ of 998 to the world if he doesn't sign the merger. Xia Lei, however, realises that Fan Fan had been an agent of ZN all along, and uses this to destroy his test results when she is exhausted from sleeping with him, and then blackmail everyone else into leaving him alone by threatening to destroy his technology.

She tries develops an antidote to Xia Lei's self-destructive sperm in order to allow him to impregnate her and pass on supposed super-human offspring but Xia Lei develops a counter as he does not wish to impregnate her, although he does help her gain the position of Chief of the ZN Bureau by using his 'connections' with Ahn Geugan.
