Uchiha Izuna felt only an itch in his eardrums. Soon, blood flowed from his right ear. He raised a hand to wipe it away, only to find that the blood was black.
His pupils contracted. Poisoned blood. Damn it, had he already been poisoned?
"Oh? You noticed? That is only natural. After all, you are a powerhouse capable of reaching Emperor Rank. It would be foolish if you could not detect it."
"This poison came from Werewolves. Werewolves have keen ears and sharp eyes, along with acute perception and a bloodthirsty state. Before I reached the King Realm, defeating a Werewolf alone would have been somewhat difficult."
"So I considered how to cripple them. Thus, I developed a virus. This virus is colorless and odorless. Once it touches the skin, it takes root and penetrates, circulating throughout the body with the blood."
"After infection, it destroys their ears first, then their eyes, and finally their sense of smell. It is also highly contagious. Once enough time has passed, it causes muscle spasms, organ failure, and cardiac arrest."
Ōtsutsuki Eki parted his lips slightly, clearly delighted. During their previous exchange, he had been quietly poisoning Uchiha Izuna. After fighting for so long, the virus had likely already spread throughout Uchiha Izuna's body.
Anger filled Uchiha Izuna's eyes, but it quickly subsided. Anger could not solve anything. Only calmness would allow him to gradually find a way to defeat his enemy.
The virus was continuously replicating inside him. If left unchecked, it would soon completely destroy him and make him lose control of his body.

Uchiha Izuna recalled how people in the past often fell ill from drinking raw water because of stomach problems, so they gradually learned to drink hot water.
Hot water. Boiling. Most viruses
