"The Pill Recipe is correct. It's been the same since ancient times. But it does have a flaw, one only a Tier 5 Alchemist can spot."
Qiao Sheng stared at Li Chang'an, disbelief filling his voice.
"Li Chang'an, are you a Tier 5 Alchemist?"
"Do I look like one?"
Li Chang'an shook his head. He understood why Qiao Sheng was so shocked.
The Pill Recipe was too complex. A Tier 4 Alchemist would struggle to understand it, let alone spot a flaw.
His rank as an Alchemist was not high, but he had learned many special techniques from Dan Chenzi's Notes. He had also received guidance from the Legacy of Mu Yixin, a Prodigy of the Alchemy Dao.
Though he was only a Tier 4 Alchemist, some of his attainments in the Alchemy Dao already approached, or even surpassed, those of an ordinary Tier 5 Alchemist.
That was why
Li Chang'an had spotted part of the problem.
"This Pill Recipe could be simplified further. But its ingredients are so hard to obtain that, as long as it works at all, no one dares try."
"Right. My master said the same thing."
According to Qiao Sheng, Heavenly Lord Wansen, a Tier 5 Alchemist, had said almost exactly that.
The Pill Recipe had flaws, but preparing the ingredients it required and following its steps would still produce a finished Spirit Gathering Pill.
In other words,
it was not the best Pill Recipe, but it worked.
Because the main ingredient, the Spirit Gathering Flower, was so precious, many had noticed the recipe's flaws, yet no one dared improve it.
A failed attempt could waste a Spirit Gathering Flower.
Even for a Nascent Soul Immortal Sect, that would be a grievous loss.
Just then,
a thought struck Li Chang'an.
