Noelle, on the other hand, circulated her power calmly. This circulation gradually turned violent.
"Sacrifice Sword," muttered Noelle. Fire flared up on her blade. This fire was compressed to become another layer of the blade, turning the black blade purple.
Her brown hair turned black.
She took a step forward while raising her sword. There were countless aliens in front of her. Normally, she would cut them down one by one, but Noelle remembered Xolotlâs advice.
"The darkness in your heart is not necessarily a bad thing. Normally, people can unleash 80% of their potential at all times. When you are calm and enter the zone, you can probably release 90% to 100% of your potential. However, anger or any dark emotion can allow you to unleash 120% of your potential for a short period.
"Anger can make you strike harder, but it doesnât necessarily mean you are getting stronger. So, Iâm going to ask you, what is the dark emotion in your heart?"
Noelle could only think of one emotion. It was anger. She was sad, but the sadness never lingered as people had to move on. She had a lot of people around her who would support her through her sadness.
However, there was one emotion that lingered in her heart. She was angry that she couldnât do much for her grandfather. She was angry at her own powerlessness.
And that was why this anger would be converted into strength.
Noelleâs violent anger pumped her blood even stronger and faster. Her eyes were burning, as if tears of blood flowed down her face.
A warrior class alien finally reached her, trying to take advantage of her carelessness to hit her.
Noelle suddenly took another step forward and swung her blade lightly. Her movement was so smooth that it felt as if she hadnât moved at all.
However, the slash not only cut apart the warrior class alien, but it also released a sword strike that ran through the ground, cutting anything in its path. The sword strike traveled for at least a few hundred meters and cut down dozens of aliens before it disappeared.
"..." Noelle gritted her teeth. This sword strike was nowhere near the power that her grandfather possessed.
The fact that she hadnât reached that level yet angered her even more. That was when the second piece of advice from Xolotl rang in her mind.
"Remember. You can be as angry as you want, but you need to keep that anger inside your heart. Your heart can be black, but make sure that your mind is cool at all times. If you canât separate anger and rationality, you wonât be able to control this power."
"Huuu..." Noelle took a deep breath, trying to separate anger and rationality.
She saw the aliens rushing from the side.
âDo you think I will let you pass me?â Noelle shouted inwardly before twisting her body to the side and swinging her blade diagonally.
The anger further amplified her power. In addition, Duke Murmurâs flame was infused into the attack as well.
This sword strike hit the ground, left a huge mark stretching over a hundred meters, and the flame of hell then rose from the shallow abyss.
Her strike killed many aliens, but Noelle wasnât satisfied yet. She remembered the power Nathan possessed. If she couldnât even reach this level, Nathan would leave her behind. There was no way Nathan would bring any weaklings to a much more dangerous battlefield.
That was why her anger intensified further.
"Keep getting angry until you are about to lose your rationality, but donât forget to never lose that rationality." Noelleâs eyes turned bloodshot.
She raised her sword one more time and swung it horizontally as if she were imitating her grandfatherâs sword.
"Zeroth Sword!"
The sword strike flew sharply, cutting all aliens in its path. However, it could probably only touch 30% of her grandfatherâs power.
"Not enough!" Noelle shouted. Her vision somehow turned red as if blood had coated her pupils.
But the energy from her body had increased even further. The fire couldnât be controlled anymore and erupted from her body. This fire was even more violent than what Duke Murmurâs fire was capable of.
"!!!" Duke Murmur had been silent the whole time as a sword. But this was actually a sign.
Duke Murmur never thought it was possible, but it looked like Noelle was approaching the borderline of madness.
"Demonic Sword!" Noelle muttered. She knew she couldnât stay true to her original path. The moment she accepted that anger into her body, her sword would never be pure anymore.
But it didnât mean this path was wrong. The sword was meant to cut down her opponent, no matter how strong they were.
That was why it would be fine if her sword were tainted. As long as she could control that tainted power and improve her sword, she would descend into the abyss.
No more. She didnât want to lose anyone else because of her powerlessness.
"Demonic Flamante Sword Style. Purgatory Line."
Noelle swung her sword one more time, producing a sword that no one had ever seen before.
This sword strike was blazing like the hell flame that Duke Murmur possessed, but it had been compressed to a single line rather than a flame wave.
Although it had yet to reach the level of Sullivanâs Zeroth Sword, it could be said to possess 60% to 70% of its power.
This sword strike looked like a line that differentiated life and death.
The aliens were trying to avoid it, but their lives were being pulled into this line.
More than two hundred aliens got their bodies cut in two. Several warrior class aliens tried to stop this sword strike, but they ended up dead.
However, this sword strike was like a double-edged sword to Noelle. She still couldnât fully control that emotion yet, so her rationality was dissipating further.
There was a reason Xolotl wasnât picked to assist Nathan in this fight. Nathan wanted him to take care of Noelle.
That was why Xolotl had landed next to Noelle, trying to calm her down before she got possessed by that violent anger.
To his surprise, Noelle actually spoke to him. "Donât say anything. I will conquer this anger by myself!"
Xolotl halted his steps in surprise. He could see that the blazing anger in her heart was gradually suppressed without his assistance.
It looked like Noelle was one step further to controlling this power.
