Since Eli came out of seclusion, they have been working nonstop to implement the idea of embedding spiritual powers into the potion.
The initial testing made them realize that for the spiritual powers to successfully be infused in the potion, the herbs themselves must be nurtured with powers as it grows.
But the problem was, the Emperor's temporary measure could only last for three days at most. After a series of discussions, they concluded that they had to employ the power of the elves to solve the problem of nurturing the flowers.
With the Palace and the Temple's support, along with the deep connection of Kayden and Eli with the Silver Dew Elves, they were allowed to borrow a piece of land on the inner section of the Silver Dew forest to cultivate the herbs using spiritual powers.
They also asked the elves to use their magic to speed up the growth of the herbs needed for the potion, especially the most important one - the Silver Woodbine Flower.
With the help and support of everyone, they manage to grow enough herbs to conjure the first batch of test potions.
Working straight for two days. Finally, they managed to develop the prototype potion according to Eli's ideas.
The first type used the normal spiritual power that came from the High Priest and the Temple Knights. The second one used Eli's holy powers as the Subject of the Oracle.
During the testing, they were in a predicament as to how they would test the potions. They only had overnight before the third day comes, and most probably on the third day the enemies had already figured out the First and Second Prince's route and tried to go again.
While Eli was confused as to why the rest was obsessed with finishing everything within three days, she thought that everyone was mindful of her time to go back to training again.
Up until this time, Eli was still oblivious to the fact that there was chaos in the Capital and a mysterious Lord Raven was targeting her.
"Now now… we just lower our guard at this point. We are pressed for time and we have to present the prototype to the High Priest and His Highness for trials!" Kayden clapped his hands seemingly recharged from the exhaustion.
"En… but how shall we demonstrate the power of the potion in their presence?" Nathan blinked and asked everyone.
"Such a trivial matter you worry about. Of course, we will use it in front of them by using the captive Igor as the subject! Who else could we use as a sampler but the guilty one?" Keren rolled her eyes at Nathan's question.
As such they immediately called Leon and the High Priests into the testing room with the clueless Igor being observed through the two-way mirror.
With the High Priest's permission, they were able to carry out the tests and proved that the curse was effective on human beings.
Of course along the process, Igor was subjected to gradual torture as the guinea pig. He was repeatedly wounded by his own cursed weapon, with Kayden inflicting his wounds ranging from minor cuts to the most severe ones.
Eli trembled as she watched the process. The scene of Elise being subjected to the same kind of experimentation flashed on her mind, making her want to spill her guts out.
Leon covered Eli's eyes and pulled him gently into his embrace, he knew that Eli possessed Elise's memories and the activity reminded her of Elise's dark past. "Don't push yourself, you can leave the testing to Dr. Einz and the rest."
"But…" Eli wanted to protest; however, she met Leon's earnest eyes as he shook his head.
"Dr. Einz knows what he is doing. You've done enough by lending them your powers and sharing your ideas." Leon answered, however in his heart there was a sentence that he opted not to speak aloud - 'Besides, I know that Kayden was now doing his own way to avenge Elise's death.'
He knew that what they were doing was no different from the evil ones, however, they were standing on the other side of the spectrum. If they didn't do this to Igor, shall they do it to their own people?
As such Eli closed her eyes and gradually slept in Leon's arms while the rest of the testing activities were carried out.
When the first light of the third day came, the proceedings of the testing were also done. Leaving them all in a daze.
Every test from the first level to the last showed that the potion had the power to eradicate the curse power.
The first type of potion with normal spiritual power was enough to cure the power of the curse that was inflicted by curse weapons. This came as a pleasant surprise for them.
This meant that the cure to the potion would be more available to every part of Prasinos without needing Eli to imbue her holy powers on every herb needed!
Of course, the second type of potion with Eli's holy powers was even more effective. Its time of effect was much faster than the first type.
They even discovered that the potion had the power to purify cursed weapons!
These results exceeded the team's expectations much to their surprise. The team of four was so shocked that they felt like walking on clouds until they found themselves back in the laboratory staring blankly at the crystalline bottle in front of them.
However, this success was only just the start. They now had to start processing the remaining herbs and make a batch of the potion for deployment.
As much as they wanted to announce it to the whole empire, keeping it secret was the key for they would eventually start the retaliation against the sinners of the Empire.
They have to clean the Empire first before they can help others.
To ensure that they would have enough materials for the Empire, Eli had to teleport back to their cultivation land at the Silver Dew Forest, also bringing back a few doses of potions as a token of gratitude for the contributions made by the Silver Dew Elves.
Eli's departure, on the other hand, had made it easier for the rest of the team to execute the final preparations for retaliation.
They have long extracted enough testimonies from Igor and Hasta to condemn the Duke and the Empress of their sins.
The Roaming Knights have also identified who among the people belonged to the cursed army, even their accomplices and trade partners.
The preparation has not just laid out inside the Capital, even the rest of the Empire was also being prepared.
The retaliation had to be a single quick move so that they would not give the Vesalas nor the rest of the traitors any chance to escape and save themselves from the punishment they deserved.
Everything has been quietly laid down in the dark, with the Crimson and Roaming blades investigating day and night since Igor's capture. The only thing to do was to wait for Leon's instructions and cue.
However, while they were moving in the dark, the enemy was an expert in moving in the dark as well.
While Leon's party was busy laying out everything, the battle in the third district happened.
They never expected that it was really after three days that the enemies would resume their operations and would immediately involve the two princes in one encounter.
The most terrifying thing was that Kazimir and Antoine's party had zero knowledge of how dangerous the enemies were.
Leon, who was actually outside the Capital on his secret base in the north, scrambled to jump from array after array in order to respond immediately to Kazimir's distress call.
Unfortunately, by the time he was able to arrive at the location, Antoine was already wounded, with his cold blood washing the ground. The knights were already fallen… gone were the lives that should have not been wasted unnecessarily.
When he saw that Orel's foot was about to touch his brother's face, a fearsome glint flashed on his stone-cold face. He unleashed his overwhelming aura and directed it all in the direction of Orel, making the other party freeze in shock and terror.
"Who…" Orel looked around and saw that everything around became dark red.
A wave of horror and a great sense of panic showered him from head to toe. He, as a person involved in all sorts of evil, had never encountered a person who could make him feel a deep sense of dread over his entire being.
"You dare to hurt my big brother…" A cold voice that seemed to come from the depths of hell sounded from everywhere Orel could hear.
He realized that he was suddenly transported to a little world where a pair of large omnipotent eyes watched his every move.
The only thing he knew was the enemy was far stronger than anyone he had ever encountered, not even his Master nor the Empress.
"Is this an illusion?" Orel mumbled, greatly confused and trembling.
"Which hand…" The large pair of eyes above the asked again with his fear-striking voice.
"Who are you! Show yourself!" Remembering that he had absorbed cursed power early on, Orel found the courage and replied to the voice.
The voice seemed to not take his question to heart as he continued to ask, "Which hand did you use to hurt my big brother and his men?"
