Inside the research lab, a young man ran into and excitedly called an old man.
"Professor, there are people in the basement." The man shouted in an excited voice.
Hearing this, the old man was startled, and a hint of expectation flashed in his eyes.
"Is it the army?" The old man asked, but the young man shook his head.
The old man was Tang Cheng, a renowned academician in the field of aerospace aerodynamics.
As for the young man, he was Tang Cheng's assistant and his name was Li San.
"It's not the army." Li San said and began explaining.
"There is one man, three women, and a girl in the basement. However, they came in a group of more than two thousand. The rest are waiting outside the building."
For security purposes, the area around the research base was heavily monitored, and all the feed was collected in the lab's surveillance room.
