Coincident?

The snake hissed after hearing Alex. "What's your request?" it asked directly into his mind.

"I need the poison of a Two-headed Hydra for my left arm's recovery. Can you perhaps help me with that?" he asked.

"I can," the snake hissed. 

"Alright, that settles it then," Shen Jing. "You can go and happily roam the poison valley where everyone else would die with a single breath."

Alex looked at him with a weird face. "That's very morbid of you," he said.

"Haha, I'm kidding. Most people that come here will know to bring a poison repelling artifact that will repel poison in the air. They will also come with tons and tons of antidotes. So it's unlikely anyone would actually die."

"Unless they end up beating beasts like him," Shen Jing said while pointing to the hydra who hissed.

"I see," Alex said. He didn't know such artifacts existed, but now that he thought of it, he didn't know what sort of artifacts existed exactly.
