"So that's how it is ..."
At the same time, Lu Xin placed the memory sand back into his black bag.
He saw that there was an additional grain of sand in the hourglass.
So he understood how to use this hourglass. As long as he used it to take away other people's memories, the sand inside would increase. However, if he changed something to cover other people's memories, the sand inside would decrease. He had been using it to disrupt other people's memories all this time, which led to the sand inside decreasing ... No wonder he used to think that it could be used without any care.
Lu Xin placed the hourglass in his pocket and said softly, ""Little sister, it's our turn."
When the younger sister heard Lu Xin's words, she immediately rubbed her hands together in excitement, ""Can I play to my heart's content this time?"
Lu Xin turned to his excited sister and shook his head with a smile. "The things you usually play with are too small."
