After demonstrating this, the Priest returned inside the city gate, extended his arms, and took down the burned-out torch from the high wall to replace it with a new one.
Ye Nai saw several burnt-out torch bottoms on the ground and suddenly realized.
She took out her cellphone and quickly noted down the current time to see how long a torch could last.
Then, she put the Priest into the Space.
His usefulness had ended, and it was time for him to rejoin his companions.
Back at the scene, Ye Nai first put away the half-filled canister of unknown powder, then checked the five canisters in the cabinet, all but one of which were full.
Ye Nai was satisfied and collected all four full canisters.
Then, besides the food with expiration dates which she stored in the Space, she stuffed the rest back into various rooms in the city tower.
