Chapter 254: I've Let You Down

Su Han was powerful, but so what? The Gu Doctor was even more terrifying now, and even Sword King, such a master, would not scare the Gu Doctor.

The Gu Doctor emitted an evil aura all over his body. Even Zheng Xing, who collaborated with him, grew more cautious in his heart.

This was someone he couldn't control; he had to be wary, but he could also use him to deal with Su Han.

"Gu Doctor, rest assured, the Zheng Family will prepare the items for you as soon as possible," Zheng Xing said.

He didn't know why the Gu Doctor needed those herbs; they sounded extremely rare, and even his wealthy Zheng Family couldn't gather them quickly.

Moreover, were these herbs related to killing Su Han?

Zheng Xing didn't ask further, and the Gu Doctor could naturally guess.

"To show my sincerity, I'll take care of a few more for you," the Gu Doctor said with a sinister laugh, before turning around and leaving.
