Fang Zheng had played a game called "Command & Conquer" before, in which one of the factions had a machine gun turret building that could attack both air and ground targets. Fang Zheng's favorite thing to do was to quickly advance technology at the start of the game, and once he had access to machine gun turrets, he would only build those. After all, machine gun turrets didn't cost much; it was just that their range was limited, but Fang Zheng was very patient. He could spend an entire morning deploying machine gun turrets across the entire map, all the way to the enemy's base entrance.
And then...there was no "after that."
And now, Fang Zheng planned to do the same, believing multiple turrets were the mainstream of the future. If you haven't won, then certainly, you don't have enough turrets. As long as there are enough turrets, no problem is a problem. So as long as there are enough turrets, any problem can be effortlessly solved.
