Big Brother Protects Mankind, What's Wrong with Using Space-Based Cannons?

"Put your bags on your back, and the moment you leave home~" In a game world composed of countless spaces, Wang Yufei, who was over 18 years old, was qualified to enter the game space, and happily entered the D-level game space - the Biochemical Pyramid. Holding the m16 in hand, he looked at the biochemical ghosts under the platform. He was about to cry. At this moment, this song rang in his ears, and the song came from another cute new player next to him. "Brother, what time has it been and you are still singing!" Before I could say anything, I saw the person next to me slowly floating, with golden light shining, and he was clearly wearing a mecha! Immediately afterwards, another golden light fell from the sky, impartially, and the twenty-seven biochemical ghosts were instantly wiped out. The whole space was boiling. "Wori, I remember there are no mechas or space-based cannons in this game space?!" Wang Yufei: "Brother, what's wrong with using space-based cannons to protect humans?"
