Upon receiving news of the enemy invasion, the guards immediately contacted their superiors, and, having received the message, the person in charge of the entire research facility swiftly contacted the head of the institute.
Bad news, we've been attacked!
Good news, according to the Undying People who escaped, there are only three attackers.
The person in charge issued orders for the Undying People and the facility guards to quickly set up a new defense line, especially the roads leading to the important areas of the research institute must be strictly controlled.
"If the outer defenses can't hold, then lower the gates."
"If the gates can't hold either, then initiate the self-destruct sequence and destroy all research data. If even one piece of data leaks, we are all dead, understand?"
The person in charge was seething with murderous intent, causing those beneath to break out in cold sweat.
