Seeing what Li Shi Ying did, Long Ao Zhen quickly realized that what she was doing, was the true method to solving this problem. Oh God, it turned out to be so easy! Why the heck didn't he focus on three stones before??

KRIEET….

The scales moved again and this time, it was balanced. It means the one lighter than the rest was the stone Li Shi Ying didn't put on the scale, the one left behind.
