Now that Su Yuan has been promoted to an Alchemy Grandmaster, he is already capable of refining the Sun Spirit Pill on his own, though there is a failure rate, it is not that urgently needed.
And under Su Yuan's command, perhaps only Mo Fei really needs the Sun Spirit Pill.
Antonios and Ashley have just broken through, their foundations are unstable, and their accumulation is insufficient, so they need time to settle. Getting the Sun Spirit Pill now would not allow them to break through.
As for Su Yuan himself... a single Sun Spirit Pill wouldn't have a transformative effect.
Su Yuan said, "Take it back, Branch Leader Jing and the other branch leaders, they all deserve this elixir."
"This... very well." Xu Hengjiang nodded, then asked, "Then is there anything else that Master Su needs? Do not hesitate to ask, as our Storm Alliance will oblige!"
