331 B-Grade Energy Explosive Bullet!

"Ping!"

A gun had sounded!

For a moment, Feng Luo indeed did not react, but he was in a diligent and prudent attitude once he started, making him still the first to react!

With his finger pressed down on the trigger, from the barrel of the Eye of the Thunder, a bullet carrying a faint blue glow burst out!

But this was not like the Energy armor-piercing bullet from before!

Because the speed of this bullet was far slower than the Energy armor-piercing bullet, and its bullethead was also significantly bigger than that of the Energy armor-piercing bullet - within it was a unique structure.

Of course, the slowness was in comparison - the flying speed of this type of bullet was undeniably above 400M/S, thus, in not even 0.05 seconds, this bullet had already collided with the charging horde of Elite Black Beetles!

"Boom!"

In the middle of the passageway, a blue-white Energy field appeared in an instant.
