The phantom weapons form a domain around Salvin and any bird that gets near it gets shredded. Some Phantom weapons venture out of the domain to harass and fight the birds. These ones wear out quickly but they are easily replenished by creating more.
His eyes aren't like his brother's or his sister's. He has normal visual acuity and can slow down his perception. The special thing about his eyes is that they grant him the ability to create, maintain, and control millions of phantom weapons. His eyes enable him to wield numerous weapons. That is why he is the one-man army. What makes an army other than the number of weapons that they wield?
Phantom weapons are created using the fourth step of weapon mastery and are hence limited in number by the strength of the divine sense and the amount of momentum available. His eyes eliminated that limit by making the momentum of the world freely available to him.
Even if others can create an unlimited amount of phantom Weapons, they wouldn't be able to control them precisely. Soverick can create thousands of phantom weapons but they can only go in one direction. If he needs to control them, then he has to be in contact with them. Salvin doesn't need contact to control thousands of phantom weapons. His eyes with 360 degrees of vision direct them with such precision that all of the weapons might as well be wielded by different people. That's why he is called the One-Man Army.
Salvin can wear down stronger foes if given time but the power difference mustn't be too great. He can take on multitudes of rank 5 birds with some difficulty but a few rank 6 birds will prove to be too difficult for him because his base damage won't be able to overcome their defense no matter how many phantom weapons he has. Sometimes, quality is always better than quantity no matter the amount of quantity.
His eyes grant him flexibility, unlike Salvos. Salvos is a one-trick pony with a very obvious weakness. If someone is immune to his flames then he wouldn't kill them so easily. A fire elemental for example loves flames and a fire dragon won't be daunted by his attacks. Of course, Salvin has his weakness of having a weaker attack but he can't be overwhelmed by numbers and he can use his ability in different ways.
Salvin's eyes glowed bright silver as he churned out more phantom weapons from it. He cheered his phantom weapons on as they slaughtered the Ravens.
He yelled excitedly, "Get them. Get them. Get them all."
He continued to attack the birds and they continued to throw themselves at him in their suicidal attempt to kill him all the while grinning with glee. His bloodlust has been awakened so he wants more violence. Plus, it is not in his nature to give up first. That might indicate defeat which he is not going to admit. So if anyone is going to give up, it has to be the Ravens. He will continue to Slaughter them until they back down.
The Ravens didn't give up. It seems that the Arena spirit has taken offense because of his attitude. Slaughtering the birds became easier when he reached rank 5. Things changed after he killed enough birds to reach rank 6. A flock of rank 7 birds each with the ability to manipulate world power came to put him down.
He roared fearlessly to the newcomers, "Come at me. I'll slaughter all of you just like I slaughtered the previous ones."
The previous scenario did not repeat itself. It seems he has been outclassed again. His phantom weapons can't use world power yet so they can't match the rank 7 ravens. The phantom weapons struck them harmlessly and bounced off their world-power-infused bodies. The Ravens quickly broke through his domain. They almost overwhelmed him and killed him. If not for using the phantom weapons as a thick defensive cloud around him then they would have gotten to him. He narrowly escaped all the while swearing and cursing the birds.
"You haven't seen the end of me. I'll be back! I'll be back! I'll be back!" His loud hysterical voice rang out through the forest.
The people that heard him only have one thing to say, "Oh no, not again."
They have heard that same hysterical voice before promising the same thing. Salvin promised this new enemy the same thing he promised the previous rank 4 Ravens. Then he went on a killing spree murdering everything in sight both monster and battle sage monkeys alike.
He became a hurricane of blades roaming the forest looking for power so that he can return to deliver retribution on the foul birds that have maligned him. The hurricane is around 100 meters in diameter and it is composed of blades not wind. It kicks up wind but that's not the only thing the hurricane does.
This hurricane of blades ripped up or shredded everything they came in contact with. Trees are not uprooted, rotated, and flung as a normal hurricane should do. They are shredded into wood shavings. Competitors cursed and ran away from the crazy hurricane while monsters howled or whined as they ran away from the crazy hurricane.
Salvini isn't wasting his time fighting the Ravens. The most important thing is that he is having fun. He is not like his silent and moody brother or his scheming and conniving sister. He likes to have fun above all else. He is also gaining strength.
Killing the Ravens with a maddened motive for vendetta is a proven method that earned Salvin the unique feat of one against 1,000,000. Soverick earned the unique feat of one against 10,000. Soverick doesn't have the craziness to take on 1,000,000 enemies.
Besides, Salvin is also quickly climbing the ranking list because of the amount of kills he has. Soverick has quality of kills on his side but Salvin certainly has quantity of kills on his side. It is the advantage of never backing down.
