It was unwise to enter through the front door, but Jiang Chen didn't plan to do that in the first place.
The drone can take care of the reconnaissance.
He ordered the older soldier to notify Cheng Weiguo and ask him to bring some soldiers for backup. At the same time, he ordered the younger soldier to stay by the back door of the mall to prevent people from escaping.
After doing all this, Jiang Chen took out a hummingbird drone from the storage dimension. This type of hummingbird drone was not attached to a machine gun, but rather a set of light multifunctionality reconnaissance device. It would complete any reconnaissance mission and was a convenient tool.
But Jiang Chen was not completely satisfied. After deliberating for a moment, he also attached two fist-sized sticky explosives on top of the drone as he utilized the remaining load.
