If you don't reciprocate, it's impolite.
Earlier in the laboratory, Li Qinyi and others attempted to steal techniques. For Qin Chuan, it was hard to believe that Jiang Banxia wasn't involved.
Even if Jiang Banxia didn't give the order personally, she had to be aware and compliant.
Therefore, seizing such a rare opportunity, Qin Chuan decided to make them pay dearly.
Additionally, he didn't want to have too deep a connection with the Phantom Group, simply put, he didn't want to be bound by the elaborate rules of the Phantom Group.
Yet he needed the herbs from the Phantom Group.
This was a perfect opportunity to negotiate the terms.
Smart as Jiang Banxia was, she naturally caught on to the implications in his words.
"Mr. Qin, state your terms."
Jiang Banxia's emotions calmed a bit, returning to her usual noble and cold demeanor.
She wasn't afraid of Qin Chuan wanting something in return.
