This requires Bees or Lightning power, adult builders, and children for distraction. The totem is guarded by one or two orange masks and a red mask. The red masks will not chase your villagers. You need something that will distract both types of guards. The easiest for doing this is with the lightning power, which is 100 energy. If you have this ability by this time, use it. If you do not, then use the bees. Hit the totem with lightning and the guards will run away. As soon as they are far enough, drop every adult you have on the totem to dismantle it. Orange guards may return early or appear from the lab. If they do, distract them with children while your adults are tearing down the totem. If the red guard returns before you finish, move your adults back to farming or building and let your energy build again. You can accelerate this process by double collecting relics. Hit the totem with lightning again if necessary, then finish pulling down the totem. Once the totem is gone, the guards will leave and you can access the lab.
