The minimum entry standard for a hacker is 6 intelligence points, which is the highest intelligence point a player can obtain in the game.
According to the standards of the cyber world, players with less than six intelligence points can forget about becoming hackers; they can barely enter Cyberspace. Their brains simply can't support that massive demand for calculations in Cyberspace—if they're not careful, even the most stable intranet could crash altogether, let alone the old network with danger levels far exceeding the intranet.
Then, in the already low intelligence point situation of ordinary players, they further reduce their computing power using virtual machine technology. So, in the eyes of the cyber life forms that survive on the old network, players truly seem no different from naturally disabled dimwit babies.
