"This should be professor Bruce's lab building. According to the information the secret agent ordered by us got today, Professor Bruce should not be in the lab today."
"So as long as professor Bruce is not here, the security of the whole laboratory will be greatly reduced. This will be the best opportunity for us to get information!"
One of them looked at the lab building in front of him and said lightly.
The other man nodded after hearing that and made a decision immediately.
"Let's go inside now. The patrol outside should be about to change shift. Taking advantage of this opportunity, we can enter the lab building!"
It was nine o'clock in the evening. Even if the street lights around were on, there were still many blind spots with black vision.
Or in some extremely dark places, if one didn't look carefully, it was easy to not find the person hidden in the darkness.
The two of them sneaked to a wall of the lab building, and above their heads was a closed window.
