"Put it back in the position it was just now." Chu Molin picked up the block and issued the command.
This time, it took them much less time to put it back in place. Chu Molin put the block in front of them, but before they could take it, Yu Chen, who was in his arms, took it and tried to get down.
Seeing this, Chu Molin didn't say no, instead, he swiftly put Yu Chen on the seat, squatting in front of them to prevent them from falling.
Yu Chen picked up the block and put it where Chu Molin had just placed it, then picked up another block and placed it on top. He continued to stack the blocks until they were all in place and did not fall again.
All three children looked at Chu Molin in unison, hoping he could explain why this had happened.
"Do you want to know why?" Chu Molin asked the three children.
"Yes." Jing Tao responded, while brothers Yu Ze and Yu Chen only nodded.
