Collect Elements

You come to a world where there is a man who collects elements crazily.
He needs your help to restore the shocked and destroyed world, but in the process, you find that there seems to be a story behind him?

How to play the game:
1. Single person or team challenge, 1-5 people, pick up the electrons on the ground to the backpack, find the 18 element disks in the map, and arrange the electrons correctly into the orbit according to the ground state (standard state).
2. The game has timing and world ranking. You can repeat the challenge to rush the list~
3. The teacher can form a group of five people in the class to compete to see which group can win first.
