After the 'Brain Concussion Plan' was activated five years ago, Professor Mo Xuan and the other spectral Cultivators had gathered critical data during a full-scale examination of the star brain while running pertinent cracking and research. They had found out methods to hack the crystal processor and paralyze it instantly!
There was short-distance, point-to-point communication between Li Yao and Sparkle via a mechanism that was similar to that of the Great Pagoda VII. It was encrypted seven times and barely monitorable.
However, such a way of communication would trigger very immense spiritual waves, which could be noticed by other people easily.
It was why Li Yao had not reached out to Sparkle in the past day.
But right now, Heavenly Saints City was in chaos. Countless spiritual waves were flooding in space disorderedly. He did not need to worry that somebody might notice the anomaly anymore.
