The camera is sticking by the mountain so that it won't be noticed by those two powerful people.
Because of that, even though Fred is hiding behind the mountain itself, he is still able to watch.
He put his focus back on the battle of the two below and tried his best to process their every move.
After a while, he sweated and said, "This two are rally monsters. I can already see myself dying just by nearing them because of the shockwaves of their every move and technique."
Every time the two hit each other, it sounds like a bomb exploded and the shockwaves are enough to blow big rocks away or even break it to pieces.
The two seem to be similar in strength as they did gain any advantage throughout this whole time that they are exchanging moves.
Because of that, Lucid jumps back a few meters away to distance himself from the captain.
