This is not the first time that they are being invaded by demon kings and this won't be the last time. The fight with demons is eternal. They have even fought 5 demon kings working together and they managed to be victorious. Three demon kings working on their own will be a walk in the park. This battle will be done in a few hours at most and they will be able to return to their lives soon.
The metal ball that is the Celestial Supreme tightened as they became closer to Aeternus. It doesn't have a face so tightening the weapons that make up its body is the way for it to prepare itself both in body and mind for the upcoming collision. It was never up for question if they would choose to block Aeternus or not. The Celestial Supreme is their strongest Celestial and he did not become the strongest by giving up ground during a battle.
That is the thing about metal. When it possesses an edge, it cuts through all opposition. That's why Metal is the element with the highest cutting power. The Celestial of Metal is the sharp edge of this formation. It is its job to cut through all opposition. Then its followers will grind down the chunks of those that he breaks apart. Aeternus is about to collide with the sharp edge of this formation and the Celestial Supreme intends to make sure that he will regret it.
Three silver phantom blades suddenly appeared above them. They are colossal things more than a kilometer in length. They appeared in the sky of the battlefield and swung down upon Aeternus. Other phantom weapons began to appear around the sphere of tightly wound weapons. The Celestial Supreme is going all out.
Several phantom weapons appeared in different shapes and sizes around the Celestial of Metal. Shields are the predominant ones. They formed an implacable defense around the Celestial of Metal. Then Several blades formed and began rotating around the Celestial of Metal, just beyond the shields.
Anyone that wants to get to the sphere must pass through the blockade of weapons and shields. That is unlikely to happen. Most become mince meat before they get into close combat with the Celestial of Metal.
The shields will delay them enough for the blades to go to work on them. That is for when they approach him. Even if they don't, the large phantom blades descending from the sky are a deadly attack to contend with. So the Celestial of Metal is more than happy to attack from afar and grind down its enemies from within the safety of its shields.
Aeternus wrapped the four fingers on one of his meaty thick hands around the hilt of his claymore. He brought the claymore forward from where it was hooked to his back. All four of his hands clasped around the length of the hilt. They each held on to a portion of the hilt, then they separated from each other. The 10-meter claymore was divided into four. Each one is similar to the other and they were held by the four huge red arms.
A torrent of powerful chaos energy entered the black blade of the claymore and made the red runes on it shine with a deep red light. The black blade shined too as if coated in blood. Then he spread his four arms apart and flapped his wings to make himself roll in the air. He swung the four claymores in a wide circle around him and made them discharge the compressed energy within them.
Four arcs of energy flew upwards against the descent of the silver phantom blades. His arcs of energy are just 10 meters long. They are very tiny compared to the 1-kilometer phantom blades descending on him like the wrath of heaven. Size isn't all that matters in a fight of their level. In fact, it is almost irrelevant. But in this case, size won in the clash.
The small arcs of energy cut into the middle phantom blade and failed to cut all the way through. They met with a resistance comparable to cutting into a real and tough colossal weapon. The four energy arcs cut halfway into the phantom blade and got stuck inside of it because of the resistance they encountered.
By every look of it, Aeternus's attack failed to rebuff the phantom blades but he didn't attack the phantom blades again. He made more arcs of energy but he sent them forward to attack the formation of Celestials.
He didn't pay the phantom blades any more of his attention despite the fact that he had only attacked one of them instead of all three. The one that he even attacked is still whole and it is continuing its descent towards him. His attention was taken completely by the Celestials. They have all begun to attack him and the threat they pose is immediate compared to the descending phantom blades.
The Celestial of Metal is not the only one attacking him as they get close to each other. Torrent of fire, Lances of light, blades of darkness, spikes of earth, water blades, and earthen boulders are raining down on him. It is an avalanche of attacks if there was ever one. He had to defend against them or risk being torn apart before the colossal phantom blades get to him.
Several black arcs of energy flew forward from his claymore as he swung them over and over again. The arcs clashed with the avalanche of attacks and destroyed a portion of them. This paved the way for him to continue moving forward. Unfortunately, he can't move forward easily.
He has successfully neutralized the attacks but the phantom blades finally finished their descent. It is time to pay the piper. He neglected them earlier but he can't now. Even then, Aeternus didn't bother with them. He can't dodge anyway. That's why the Celestial of Metal attacked with 3 blades instead of one.
