"This iron barrel? What is this?"
Everyone would recognize guns when they saw one, from pistols to rifles, even machine guns, heavy machine guns, and rocket launchers. People were not unfamiliar with these things.
However, at this time, these simple refugees were stunned as they watched Su Mo put his hand on the oil barrel.
Not everyone had seen a TV series or movie featuring the "heartless cannon", so not everyone recognized this famous launcher.
Among all the people, a few young people reacted the quickest.
These several people glanced at each other, with surprise in their eyes, and said in unison, "Is this the heartless cannon from the movies?"
"This can directly hurl our explosives into the kobold castle?"
As Su Mo took out one neatly assembled pack of explosives after another, and with the explanation of those several young people, everyone gradually understood what the huge iron barrel was and what a "heartless cannon" was.
