Why is mom so fierce when it rains?
First of all, during the rainforest period, our ancestors never forgot their old jobs, never slacked off in catching Bai Niao, and never forgot the lessons of acid rain. Ancestors need to develop science and technology industry (PS: Rain Mom doesn't have so many high-tech equipment in her memory, but there are). What they need is stones. From Yu's memory, we can see that Yu's mother tried hard to restore the gravel, but finally failed. Until she took away the spark of the rebel of light, the stone developed rapidly with the progress and increased the mining intensity.
In the second part of the map with rainforest, you will see a lot of caves and the hidden map shown below. Including the crab cave, there are seven caves altogether, all because of the stone cave. Because of over-exploitation, the growth of dark plants is more unbridled, so that a teammate of the weeping ancestors in the rainforest died under the dark plants, and the angry ancestors stamped their feet to deny the development of stones.
Back to mother Yu, the decision to mine stones came from mother Yu, whose character must be calm and resolute. Behaviourally, I held the gravel at first, and then the gravel slipped out of my hand, looking disappointed. Until the rebel of light appears with the spark (us), it will grasp the spark (fierceness) in our hands, put a hammer on the stone platform, and then the stardust will become a diamond stone that can float. This is mother Yu's request. She didn't mean to kill us.
