Tom's intention was actually very simple.
"The environment on Venus is too harsh, which prevents me from carrying out large-scale infrastructure construction on its surface, and from building supercomputing bases. This allowed you to exploit a loophole and seize Venus."
"Your technology is more advanced; you have the ability to carry out large-scale infrastructure construction on the surface of Venus, build supercomputing bases, and deploy a large number of unmanned combat forces."
"By conventional means, I cannot reclaim Venus."
"Since that's the case… I will find a way to make the surface environment of Venus even harsher, so harsh that even you cannot cope, to the point where large-scale infrastructure construction is impossible. This way, I can pull you down to the same level as me!"
The impact of an asteroid with a mass of approximately 24 trillion tons could achieve this goal.
