Fu Qian chose a response that quite matched his persona after realizing that the Yasui Group might have a special interest in Darcy.
It wasn't surprising for Darcy to be indifferent towards the Miracle Elixir, after all.
On one hand, compared to ordinary people, he had already gained a considerable survival advantage and didn't need to gamble with such dangerous stakes.
At the same time, due to the existence of the Night Watchman, even if Transcendents were a dime a dozen, his own safety was in a delicate balance, which didn't warrant too much worry.
Of course, the most important factor was his special hobby.
Considering Darcy's actions, if he really did accidentally transform into a Transcendent, he would've played right into Suzune's hands and would've been eliminated long ago.
Therefore, for him, the Miracle Elixir was more harmful than beneficial.
