The shopkeeper was beyond shocked.
At their cultivation level, any menial transaction involved dozens of billions and with the requirements, Sam mentioned just now, the price reaches hundreds of billions.
Nobody wants to have that much of spiritual stones, because the energy from spiritual stones can do little to nothing to them at their level and they also need to have unlimited patience to go through all of those stones.

"Okay, if you are comfortable with paying with spirit stones, then do so by all means. Fifty percent now, please."
The shopkeeper continued with the transaction and Sam took out the spatial ring and handed it to him.
