"I'm not sure yet," Hu Fei said, typing on the keyboard. "When we initially installed the security system at the base, I added a self-protection program into the system. Once the system is attacked or breached, it will automatically generate a firewall to resist the attack. However, if faced with a skilled hacker, this firewall can only hold out for a few minutes at most."
While speaking, a green sphere appeared on the computer screen. However, half of the sphere was infected with red, and the virus-like red was rapidly spreading along the sphere's perimeter.
"Look," Hu Fei pointed at the sphere on the screen and said, "The opponent's efficiency is very high. If the entire sphere is engulfed by the red, the whole base's system will be paralyzed and be under their control."
"Pull the plug," Tang Guolun suggested. "Without power supply, the whole system will shut down."
