The recipes for zombies in the special cookbook are designed according to evolutionary classifications.
The Two-Headed Zombie falls under the category of intelligent zombies, so Xiao Feng chose the "Bloody Walnut" for them.
This special dish has a significant effect on boosting the mental abilities of intelligent zombies.
[Bloody Walnut: Made from fresh sheep's blood and mutated walnuts. When consumed by intelligent zombies, it enhances their mental strength by ten percent.]
"Sheep's blood? Why use sheep's blood?" Xiao Feng became puzzled.
"Can't goat's blood be used?" Because the only available livestock in Xiao Feng's ingredient reserves were goats.
However, after a moment, Xiao Feng remembered a previous experiment report.
Sheep are purportedly the eighth most intelligent animal in the world.
Xiao Feng used to doubt that timid sheep could possess such high intelligence.
