Bo Li’s suggestion sounded crazy to say the least.
It was preposterous enough that a supermagnetic field generator needed to be built to essentially open a tunnel, and her plan required the usage of the Supermagnetic Planet Annihilating Rail-Cannon! A weapon strong enough to demolish a medium-sized space satellite with 1 hit!
"I’ve asked many experts before coming forth with this idea. All of them agree that a shot from the cannon could tear through the suspended 2,000-meter rock layer easily. Furthermore, the shot will have reached enough third cosmic velocity [1] to break through the atmosphere and perhaps even this solar system to disperse itself in space! There is no harm in doing this!"
Yao Yuan was convinced by her sound argument on one hand and conflicted by the ludicrousness of the situation on the other. In the end, he came to a decision and asked for a meeting among the Black Star space troopers.
[1] The 'third cosmic velocity' is the speed that a spacecraft needs to attain in order to be able to leave the solar system.
