Kung Fu The Way of Chi

You're a young apprentice in the "Mist Dragon" Kung Fu school. Strengthening your mind and your body every day, and progressing well.
Unfortunately there was a huge earthquake last month, and the school is seriously damaged, so Shifu Sun , your wise master invited craftsmen to rebuild the school. The day after he had to leave for a couple days to help out a friend.
He commanded you to protect the school's magical ginseng plant at the center of the school's training-square during the rebuild.
"These craftsmen will work all day and all night, keep your eyes open, and protect the plant!"
Just after he stepped out the school's gate, the craftsmen start to work, and building materials started to fall.
Can you keep the plant safe until Shifu Sun arrives back?
