"Here you go," the mad immortal handed Alex the storage bag with the forge in it. Alex took the bag and looked inside before thanking the old man.

"What are you going to do with this?" he asked.

"Make a cauldron," Alex said. 

"What's wrong with the rest of the cauldrons?' the old man asked curiously.

"They're quite weak to be useful for when the Pill Cloud forms. Every single one I use is destroyed by the lightning," Alex said.

"And this one will help you? The Pill cloud's lightning bolt transcends space and time. No matter how strong your cauldron is, the lightning bolt will strike the pill," the old man said. 

"I see," Alex said. "Still, the cauldron I will be making should remain intact even after it is struck by lightning."

"Ughh… do what you want. As long as you make me the pill in 10 years time, I am fine with what you do," the old man said.
