Control Variable Method 1

"You also know about the Calamitous Shrine Maiden?"

Lu Ban leisurely picked up another piece of smoked fish from their lunchbox with his chopsticks, which had a touch of sweetness and tasted very good.

"The Calamitous Shrine Maiden is the ruler of this island; as long as one venerates her, one can obtain eternal life."

The gloomy expressions of the two people vanished, and their tone suddenly became somewhat fervent.

"Then why don't you eat the food from this island?"

Lu Ban asked a question while picking up a piece of seaweed-wrapped rice and crunching loudly as he chewed.

"...I'm sorry."

The two men hesitated for a moment, then suddenly bowed their heads to apologize, banging their heads on the table so hard it was heartbreaking to hear.

"I'm sorry!" "I'm sorry!"

The two kept apologizing and banging their heads against the table, even as blood began to trickle from their foreheads, yet they did not stop.
