The main reason why Ying Chunhua had come to visit Emperor Sky was that her scouts had noticed the sudden gathering of forces around the imperial families right after Mao Yifeng and Tang Suwei disseminated the words of the new Emperor of Heaven. She had long known that these imperial families were very ready to revolt at any opportune time ever since Nuwa died.
When they heard that Shanxue was already reduced to remnant energy and that Mao Fuxing and the rest of the children were not really Mao Shanxue or even Ying Chunhua's blood, they started amassing forces. They were only waiting for one mistake from Lai Mingyan. One mistake was all it took for them to take him down.
He was just a child from the mortal realm after all.
