All those 20000 human Warriors begin to advance into the danger zone. Right now none of the citizens of the human Kingdom know about this big moment that all the human Warriors are going to war. Naturally that was the order from the king so none of the citizens got afraid or something reckless in their panic state.
On the other hand the king led all the human Warriors toward the danger zone while the old King also followed them but he was above in the sky. Naturally the king also followed those Warriors in the ground because as you know most of the human body did not have technique that could make them fly and only after becoming a Planetary grade warrior you are able to fly in the sky without any technique but other than that you need technique.
