Allen reached the city wall and can see warriors standing in front of the city wall to stop the monsters from reaching the walls.
On the walls, he could see the archers standing ready to attack the monster horde as soon as they come out of the forest.
There were thousands of soldiers stationed in the Central city as it is the capital of the empire.
Almost all the soldiers are sent to the walls in the Northeast except for the squads that are patrolling the other parts of the borders.
The city gate was closed for defence, so Allen can't get inside to go on top of the wall.
He kept his bow inside his shoulder storage bag and again took out his sword to defend the city.
The remaining archers from his party went near the walls to support the warriors from the back.
Since they are using grade-2 bows which use monster cores to create arrows, they will not run out of ammunition if they have enough cores.
Allen was standing next to his squad leader. They were waiting for the monster horde to come out of the forest.
"I think you can change your designation to warrior kid. You are pretty good with a sword than a bow" he said to Allen.
"You think so?" Allen asked with a puzzled look.
"I know so. Submit the form once the horde is destroyed. I'll take you into my squad" the leader said.
The archers on the city wall started shooting signalling the horde is near. The cannons placed on the walls also started firing.
"DO NOT LET THE HORDE GET PAST US. ATTACK..." Allen heard but didn't know where it came from.
He was now able to see an infinite number of big head turtles rushing towards the city.
The explosions from the archers were majestic, killing multiple turtles due to the AOE damage caused by it.
Allen started to move ahead along with other warriors holding his sword firmly in both hands. He also started to perform the mana exercise.
He saw the higher-stage warriors rush to the front leaving lower-stage monsters to be dealt with lower stage monsters.
Allen saw three low-level private stage turtles heading towards him at the same time.
He infused mana into his sword to cover it with red colour fire. It will do fire damage to the turtles and increase the penetration of his sword.
One of the turtles attacked Allen with water from its mouth. He dodged it and swung his sword against another turtle that was about to bite his waist.
The sword landed directly on the head of the turtle. The sword cleanly cut its head killing it instantly.
He attacked the other turtle but only managed to hit its shell forming a small scratch on the shell.
The turtle that is on his left again shot water towards Allen.
'Ssssshh'
Unable to dodge it, he used his sword to block it and the water vapourised as soon as it touched the sword covered with red fire.
He attacked the turtle near him aiming for its head, but the turtle withdrew its head inside the shell and dodged his attack.
He took this opportunity to dash towards the turtle that was harassing him from afar and killed it by piercing his sword to its head.
'Putich'
Hearing the sound of his brethren getting killed, the last turtle rushed towards him with fury.
'Slash'
Allen easily dodged its attack and sliced its head killing it.
He collected the shells of the turtles he killed as they are used for making armour for warriors. He can sell it for a huge price.
He also collected the meat from them to replenish his mana if needed.
It is useless to sell private-stage monster meat as it will be sold for a very less price.
He checked Serina and could see her playfully dodging two turtles' attacks making them angry.
"Serina, finish those turtles quickly and assist others" Allen said in a calm tone.
'Growl' Serina replied and killed the turtles in a single swift attack. Allen collected their shells and meat.
Allen burnt a piece of turtle meat and ate it to replenish his mana and started to defend against another 3 turtles.
Serina came close to him fighting another 2 turtles and starting to have some fun with them.
Allen ignored her knowing she is not going to change until something starts to threaten her.
Allen took 5 minutes to kill the 3 turtles and collected the shells. He left the meat as he has enough to replenish his mana for now.
He suddenly felt a little tired and the red fire coating his sword flicked and disappeared.
'I'm an idiot' Allen cursed himself. The mana he got from eating the monster's meat formed a dense cloud in his mana space.
In the heat of battle, he forgot that his mana purifier needs to be operated manually.
He started collecting the mana cloud from the collector and started condensing it and purifying it at the same time.
Doing the 7th move of the 3rd set mana exercise along with manually operating the mana purifier caused a lot of pressure on him.
He endured it and continued to do both at the same time. He was stuck in the 7th move of the 3rd set for a few minutes now as he is being blocked by the mental wall.
He saw high-level private-stage turtles starting to break through their formation and come towards them.
Since the last line was made up of private-level warriors, they thought the higher-stage warriors will handle the rest. They will fight only the private stage monsters.
