Within the Z organization, there were Vigorous Kui and Little Poison Insect, two Martial Artists known for their Internal Strength, so naturally, they were somewhat prepared for an Internal Strength Master.
Take, for instance, the closed-circuit surveillance cameras at each entrance to the tunnels.
These cameras were purely optical signal collection devices, which could not be hacked. After the signal traveled through the closed-circuit lines to the monitoring area within the Great Stockade, it was monitored by a few members with very low levels of cybernetic enhancements—they specialized in this work. These individuals had flesh and blood hands and only a single brain chip, which lacked the function to control their limbs. This way, even if someone released a "Talisman" or "curse" through the screen, they would not be immediately controlled.
Next to these members were purely mechanical alarm systems.
