After Tang Rui finished reviewing the documents in the file bag, he realized that the prototype of the protective shield had significant problems.
Firstly, it consumed a lot of energy, and it wasn't continuous energy consumption, but instantaneous, which was troublesome.
Secondly, there was a flaw in the magnetic field. Its strength varied, and the deflection angle was different, making it uncontrollable.
Lastly, the magnetic field had a limit. It couldn't withstand a shell's impact.
But regardless of these shortcomings, this device's emergence was like a key to unlock the door to a new era.
At that time, human top technology was used for self-destruction, with more emphasis on attack capabilities.
Compared to offensive technologies, current defensive technologies were significantly lacking.
For example, a main battle tank worth tens of millions couldn't withstand an anti-tank rocket costing only hundreds of thousands.
