In the blink of an eye, three days had passed.
According to intelligence from the outpost, more and more troops and weaponry were being brought in, including various heavy weapons.
In the eyes of military experts, the entire outpost had become an impregnable fortress.
As for these, Wen Yu didn't see the point.
On the other hand, the researchers from the Military Academy studying the Demon City's protective barrier had made some progress.
The operating principle of the protective barrier was likely what Wen Yu had described. Indeed, these scientific 'freaks' had even managed to measure its protection limit.
The results showed that a single nuclear bomb with a 100,000-ton yield was enough to temporarily break this protective barrier.
Moreover, according to information from a casual chat with Kuangliu, Lin Haifeng had some thoughts about this Demonic Energy Shield.
