San San was thinking too. "First, we can rule out the Medicinal Decoction and the Herbs." Ye Chuqi had handled both herself. Even if she only knew the basics, San San had been watching, so nothing could have gone wrong there. "His father personally oversees every dose the young master takes. The Mercenary Corps delivers the medicine, and although it passes through several hands along the way, I watch it the entire time. There's been no problem. So we can also rule out someone secretly tampering with it to make his condition worse."
"Mm," Ye Chuqi said. "What else?"
Perhaps Ye Chuqi looked too serious as she concentrated on San San's analysis. Joshua leaned against the carriage in an awkward, uncomfortable position, with one arm held by Ye Chuqi and his other hand braced on the carriage shaft. He didn't dare move, but his legs had gone numb—
San San continued, "You said the formula was sound. It hasn't been improved in years, but it's still the right treatment for Ghost Gold Grass, so we can rule out the prescription. As for the Ghost Gold Grass itself, we never saw what poisoned the young master, and those few scraggly stalks Duwak has don't tell us much. We can't rule out a mutation in the grass. But I can confirm that the toxins in the young master's body haven't fundamentally changed. Only the amount has. So I'm reserving judgment on the Ghost Gold Grass."
Ye Chuqi glanced at the young master, who was a few years younger than her but nearly her height, and clicked her tongue. "So once we eliminate everything impossible, whatever's left must be the answer, no matter how unbelievable it seems."
"Mm. The one who's mutated might be the young master."
Ye Chuqi nearly burst out laughing.
