The enemies remaining inside the barrel were left to Yu Dawei and the others.
The more troublesome ones among them were probably the two Black-Gold Livery Deep Sea Fishers.
Yu Dawei was fighting one of them.
As for the other...
Bang!!
A dazzling red beam struck the robot, snapping its head back and leaving a distinct dent in its forehead.
Then came orange, yellow, and green.
Each shot was louder than the last, and more powerful too.
By the green shot, the bullet had pierced the robot's head, tearing a radiating wound through the back of its head, and flames poured inside.
"It's that powerful?"
Cui Xiya exclaimed in surprise. She had never expected the Seven-Colored Hummingbird to be so astonishingly powerful after switching to rainbow bullets.
But correspondingly, the gun's recoil was also enormous.
The Long-Legged she was riding was jolted back more than a meter by the recoil, its four legs scraping sparks off the ground.
"Still not dead?"
The Black-Gold Livery Deep Sea Fisher actually managed to reboot, standing up again and raising its gun to return fire.
"Take this!"
Cui Xiya shouted, pulling the trigger and firing her fifth shot, a blue bullet.
Bang!!!!!
The tremendous gunshot drew everyone's attention.
A blue beam struck the Black-Gold Livery Deep Sea Fisher square in the chest, piercing through it and leaving a horrific wound in its back, blasting out a mass of broken parts.
After taking a shot like that, the Black-Gold Livery Deep Sea Fisher finally fell, with no chance of getting back up.
"Impressive!"
Yu Dawei exclaimed as he fought the other Black-Gold Livery Deep Sea Fisher.
But when he turned to see who it was and what weapon they were using that could be so powerful...
All he saw was a wing slowly drifting down
