Yisi felt a sense of crisis when she learned that Fang Mu was preparing to take control of Ervean.
For Ervean and she were both Blood Race Queens, yet Ervean was stronger than she.
Once Ervean joined under her banner, Yisi feared that Fang Mu would focus on cultivating Ervean and abandon her.
Yisi felt it necessary to emphasize her value to Fang Mu.
And the best way to underscore her value was to give her Destiny Instrument, which she had crafted after becoming a Blood Race Queen, to Fang Mu.
Ervean also possessed a Destiny Instrument, except that Ervean's was an offensive type.
Its power was a highly corrosive Armor Break ability.
Even if Ervean wanted to, she couldn't give her Destiny Instrument to Fang Mu,
because Ervean's Destiny Instrument was of no use to Fang Mu.
She was the first to come; how could she be surpassed by Ervean?
