Labyrinth

Zhang Heng didn't avoid the old man deliberately, opening the bag in front of him and taking out the Lego instead.

The thing he was trying to piece together this time wasn't complicated, so it didn't take long. Very quickly, he reached the final step and inserted the Infinite Building Block into it.

The next moment, a brand new drone appeared in his hand.

The drone took off under Zhang Heng's control, and under the old man's stunned gaze, he flew to the top of the maze. From there, he could clearly see the entire maze and see the changes in there. Zhang Heng silently calculated the time of each change, trying to plan a path from the middle to the center while factoring in his own speed into the maze.
