MCs formation is total crap. Calvary is highly mobile so place them on the flanks to run rings around them peppering them with arrows while infantry closes with the center in a wedge formation or sawtooth then use the calvary as a hammer to the infantry's anvil
You would think that after nearly 500 chapters the writer could have learned a few different ways to describe soldiers, their strength and all of that stuff. Blood red eyes, their killing intent was strong, they made the mountains tremble... used them in every single battle scene so far. Lacks imagination and grows meaningless with so much repetition. MC can just say "been there, done that & all I got was this lousy t-shirt for it". MC just yawns & rolls over to go back to sleep, 'wake me up when they have blue eyes & are scrawnier than a bean pole, at least that would be a change.'
