Sandevistan simulator

( Sandevistan )... it is a high-tech cyberware device that has a structural appearance similar to the human spine. It is often a device that surgically replaces the human spine. The original human spine must be removed first, and then the Sandevistan is installed.

When the user is about to activate sandevistan, they must issue a mental command from the brain. The Sandevistan will receive that signal and immediately initiate operation.

( When Sandevistan activated ) : The Sandevistan sends electrical currents throughout the user's body, accelerating the brain's processing to an extreme level and increasing the movement speed of the entire body.

( From the perspective of the Sandevistan user): The user can see that everything around them moves extremely slowly, whether it's people, animals, or objects... Raindrops will float suspended in mid-air and slowly fall to the ground in slow motion. Bullets or sniper rounds would take up to four hours to travel, yet the user is the only one who can still move normally.

But this is the opposite of (the perspective of others): They see the Sandevistan user moving extremely fast at a superhuman level, becoming a blur. The user moves faster than racing cars, all types of bullets, and explosions.

( Sandevistan ) has a runtime of 25 seconds per use and will automatically cease operation immediately. However, the user can also issue a mental command from the brain to manually deactivate the Sandevistan.

After the Sandevistan has stopped operating, the user's brain processing and physical movements will return to normal.
