They didn't know that this one-man war in front of them wasn't actually being directly commanded by Li Haotian.
The ones commanding those Superpower Weapons to attack were, in fact, the Terminators surrounding the Undead Army from outside the battlefield!
Each of these Terminators possessed one ten-thousandth of the computational power of "Sky Net"; they acted like temporary processors controlling different sections of the battlefield.
Under the coordination and arrangement of "Sky Net," each was responsible for a specific region of the Superpower Mechanical army.
For example, tanks and Armed Helicopters.
With the blessing of Li Haotian's God's Eye View, Sky Net covered the entire battlefield unfailingly.
And it was a full 360-degree, near or far, omnidirectional battlefield with no blind spots!
What they had to do was manage the combat in their allocated areas of the battlefield, as designated by Sky Net.
