Analyzing the method of flight is just one aspect.
In fact, the Prophet wants to conduct a comprehensive analysis of Lu Li.
For instance, how much energy is contained within, and what level of physical quality is possessed.
What level of power is needed to kill or destroy him.
Also, what kind of superpowers does he possess.
How much energy is consumed when using these superpowers, and so on.
The reason the Prophet wants to do this is because it knows well that if Lu Li and Pangu are not dealt with, even if it kills the great leader, it will be very difficult to truly unite the Milky Way Galaxy.
Moreover, if Lu Li is willing to intervene at the request of the Orion Arm Interstellar Alliance to "quell the rebellion," it would pose a fatal threat to it.
