The War Lord of Samsara Paradise

Samsara Paradise answered the call, and Gao Fei became the hunter of Samsara Paradise. He entered the continent of Arad and became a gunner, and learned the mechanics of the Star Sea. How far is the future of heavy firearms?
Knowledge is power, but the tuition is a bit expensive...
A group of people suddenly appeared on the battlefield, including a strong man wearing high-tech armor and holding a rocket sledgehammer, some naturally stupid women holding sickles, a handsome young man riding a white tiger holding a silver spear, and carrying two ninja swords on his back. A ninja with a sword hanging on his side...
There is also a madman carrying a heavy firearm - Black Eyes!
Everyone's eyes were filled with fear, and they turned around and ran away.
"The Bandits!"
"They are robbers, run!"
The shell exploded, and everyone stopped and turned around.
Gao Fei said calmly: "I have a deal to discuss with everyone..."
How many outrageous things have the mercenaries, bandit adventure groups, and the largest arms dealers in Samsara Paradise done here?
