Protect Leukocyte

What is it about?

Observe the numbers carried by the virus in the game, and select the two leukocytes below for combined calculation. This is a game that tests the player's arithmetic and reaction ability. In the game you need to protect the leukocyte from being attacked by the virus, so you need to observe the numbers carried by the virus, and select the two leukocytes below for combined calculation. If the value obtained is equal to number on the virus, the virus can be eliminated. When the virus comes into contact with the leukocyte, it will become contaminated and become smaller, and contamination to a certain extent will cause the game to fail. Come try if you can guard the leukocytes.
