Counter Measurement

An RF shielding might be difficult for others to counter, given that they won't know the actual specifications of the RF shielding.

Sure, Shi Tian may have obtained the data that an RF shielding was active, but that doesn't mean a simple recording of it could let them determine the type of RF shielding. 

If that was the case, then Theobold would definitely never let him approach the Railgun Blaster. 

Theobold was confident that his RF shielding was impeccable and couldn't be identified, but never once did he expect Shi Tian to hold the biggest trump card: the integrated chip.

'The IC chip can identify and figure out a way to counter the RF shielding in a matter of seconds. I don't know whether to feel blessed or wary of it.' Shi Tian thought to himself. 

Having such a powerful item might sound great, but it also horrified him somewhat. The usefulness that it had shown frequently was making him wary as he began to doubt its origins.
