Feng bujue had lied.
This was actually an obvious thing ...
Indeed, before he came to the 'government office', he had already shut down many of the sonic boom tunnels. (After one experiment, Feng bujue realized that the energy consumption of the unparalleled Inferno heat wave cannon was not as high as he had imagined. Of course, this was also related to his current physical condition. This will be explained later on), but he had definitely not shut down three quarters of the tunnel.
In fact, he himself did not know how many tunnels there were. He had only followed the route of the redundant soldiers ... And led his comrades to find and raid a few military points that were closer to the government office.
Taking a step back, as long as he spent some time preparing for something like the sonic boom tunnel, it would not be difficult to reopen it.
