These young scientists were very fortunate because Xia Fei had given them a different option. They did not have to follow the standard procedures like their seniors. Quantum Holdings could provide them with their own lab and funds. That being said, it was part of their job to play a supporting role to Harris, but they were allowed to invent and research as they pleased.
