Yi Chen reread the entire book. The first half was basically all factual information, but when it reached the most crucial section on the Plague Lord, it became a mixture of truth and falsehood.
All the information on Fish Source was true. There was no doubt about that.
However, the subsequent intelligence on the Plague Lord—including its appearance, territory, types of plague, and illustrations—was accurate, while the descriptions of its specific abilities were somewhat strange.
For example, the book described the Duke as the "master of the castle." Anyone who tried to harm the Duke would be dragged into the castle, where a plague battle would unfold. Gambling elements might even be involved during the confrontation.
It had spent over ten thousand words describing it in detail, to the point that Yi Chen began to wonder whether this was truly the Duke's ability.
For another example, the book had also included the Boss of the Fear Circus among the Plague Lords. Yet as the Boss of the First Abyss, she had become the "First Performer" in the book, possessing shapeshifting flesh and wildly proliferating hair.
It had even fabricated a legendary story about the Boss founding the circus herself as a performer. Many of the experiences had clearly been based on William's life, and Yi Chen was almost unable to keep a straight face.
After finishing this "Plague Book" of mixed truth and falsehood, Yi Chen had learned William's attitude and general plan, but there were huge problems with it.
Once the Calamities truly clashed with the Plague Lords, they would immediately realize that William had played them for fools.
They might not even need to confront a Plague Lord. They might discover the problem simply by capturing an individual with a disease focus in advance and examining its memories.
