That was all very dumb. From the end of the last chapter, you'd think the dragon was about to swoop down and burn them all to ash. Nope it just hovers in place while they collect themselves then calmy lands to confront them. So much bullshit, the battle cry, praising him for getting stronger by doing nothing besides eating, the dragon staying on the ground the entire fight, being able to use feints on a dragon.
Couldn't he have just covered the whole area in those spine plants?
