Alex took the Gluttony and changed it to the Kusanagi sword.
He extended the sword about several hundred meters. Which pierced the zombies. But that wasn't the main advantage of this sword, the strength behind this sword was so exceptional that the zombies were getting knocked back.
Which is becoming an opening for the army to attack. Because he was assisting them to kill the zombies he was also getting exp.
The endless herds of zombies are coming from everywhere.
85% of them were running by foot because they are below the sky realm.
Alex flies higher and started to lunch atomic fire missiles. He was firing 100+ missiles per second. The entire army was in awe of his exceptional firepower ability.
On the other, hand Perfect Athena was sucking every zombie from the sky and the ground, she was avoiding hitting the army.
Everything was going pretty well.
By the way, the army was using a particular magic crystal to defeat that zombie, the crystal was entrapping the zombie, and when the crystal absorbed the body of the zombie fully inside little crystal that crystal was shuttering into power. There was no way to revive or reattached those powder parts to other zombies.
"Stop! Don't kill her. Don't kill her."
He heard a woman shouting among the army. She was forbidden to kill a particular female zombie who was wearing an army dress.
He recognized her. That zombie was the one who asked his name first time in the army.
'So, she also became a zombie.'
Alex was saddened after seeing this.
"Don't kill her. She is my little sister."
The woman who was stopping everyone from killing her was crying while saying that.
The female zombie was pinned down by everyone and was gagged. They also bind its hand.
"Don't hurt her. Leave her alone."
She said. She was a 5th-level Duke. One of the upper-tier members of the army.
She pushes away everyone from her. She was strong so, no one could resist her pushing strength.
"Don't worry Nia. Your big sister is here. You were afraid of this monster, no? Don't worry anymore we will kill every zombie here."
No one could bear to see her desperate cry for her little sister.
She said while hugging the zombie.
Suddenly, the mouth gag fell from its mouth. Zombie's teeth were now free and enlarged and try to bite her.
"Look out, Mia."
Silvie shouted toward her. It will be too late to save her from her sister's zombie.
When everyone thought that it was finished for her, the zombie felt nothing but a metallic sensation in its teeth. A few of its teeth also was broken.
If Alex from the sky stabbed her mouth which also pierce her neck and the sword finally stuck onto the ground.
"Tsk, I still can't control this new form of Gluttony."
Alex expressed his dissatisfaction. Seeing this action of Alex she let her go and looked at the person who stabbed her younger sister.
Seeing this chance he points the sword toward the sky, of course, the body of the female zombie follows the sword. It was now in the sky like a fish.
"What are you doing, you mothe****r!!!"
Mia was so angered by his action that she swear at him. She flies in the sky and tried to get free her sister from the sword.
"Gravity Pull."
He pulled her in front of him and throw an atomic fire missile at him.
The body of that zombie vanished from the sky.
"Why, why did you kill her? How dare you?!"
She asked him with a roar. Athena came to Mia's behind, Mia was stuck in the air because Alex stuck her in the sky by using Gravity magic. Athena locks her arms in her behind to not to let her move.
Alex asked her.
"Then why did you kill all of these zombies?"
"Zombie? What is this??"
She stilled asked him with sorrow filled roar.
"This monsters I mean."
Alex replied.
"Shut up! I will rip your mouth, she was no monster. Princess Aphrodite, please kill this man to bring justice to me. He is the killer of my sister. I am begging you to punish him."
She pleaded to the princess.
The princess came in front of her. Alex thought she will try to finish her. But instead, she slapped her.
"Stop that, Mia. Your sister was long gone. She even tries to take it with her. She was not Nia anymore but a brainless man-eater monster."
Princess Aphrodite said to her. Mia was still in a daze after getting a hard slap from her.
"But Princess but."
She tried to refute her. But Alex stopped her.
"Now, I understand why even a stronger one became a zombie. They at least could run away from them if not kill them."
Princess Aphrodite frowned at his words and asked,
"Why?"
Alex pointed at Mia.
"What?"
Princess again asked him. She was also annoyed by his brutal action with Zombie Nia. Things could be handled in a better way in her opinion.
"Because of familial love, romantic love, friendly love. No one wanted to let his or her loved one go. They try to save them or stay with them, and that's how they became prey to the zombie and became zombies."
Alex said. Princess Aphrodite finally understands his meaning.
"Yes, you are right. It is important to have familial love. However, in this situation it's meaningless. Mia, just leave it and face the reality."
She told Mia.
"I understand, but I cannot still forgive the man who killed my sister. My mind cannot just forgive him. Never."
Mia told her.
"I see."
Princess Aphrodite looked at Athena. Athena nodded toward her understanding of her meaning. She delivered a hand chop on her neck of Mia, which made her faint.
"You need to rest, for now, Mia."
Saying that princess looked at everyone and signaled to continue the fight without thinking about this event anymore.
