I Make Advanced Technology Weapons, Shocking Everyone

Bruce obtained the Divine-level Technology System, and embarked on the road to technology powers since then!
The first day of school: I can make electromagnetic weapons!
Later: I can make steel armor! The kind of Iron Man!
Have you ever heard of the electromagnetic railgun? I can make it!
Have you ever seen a flying aircraft carrier? I can make it!
All kinds of equipment in the science fiction movies were created by Bruce!
Looking at the increasingly sullen face of the enemy country, Bruce scoffed.
What? Do you still use gunpowder guns? Out-of-date!
Your aircraft carrier can't fly? Rubbish!
Your soldiers don't have armor to protect them? Isn't that trampled on human life?
Getting mad? Is there any solution?
The enemy's army was already invincible on the earth!
It was like aliens descending!
