Although Zhen said about fighting Aaron for a servant, in reality, he simply wanted a training dummy so he could test his new moves out.
After studying from the book a bit, Zhen wants to try out a new possible application of magic such as making his body transparent to avoid incoming attacks and then counterattack right away.
Zhen was thinking about testing this theory out and right when he wants to find a person to train.
A fool appeared in front of him in the perfect timing when Zhen was thinking about it.
It's like everything is fated and destined for Aaron Flare to have this honor and duty to get beat up by Zhen.
Therefore, Zhen intentionally provoked him to not disappoint fate in pulling this string, and since Aaron Flare also pursues his Sara before.
It gives him more excuse to beat him up and his face is the kind that's asking for a thrashing to top it off.
This will be Zhen's warning for him while getting a free servant who has a powerful figure behind.
Aaron Flare didn't know about Zhen's intention at all and simply wanted to beat him up for disrespecting him.
Not only that, his crush is now taken which stabbed his heart deep. However, if Aaron came to know that the person who stole his crush is the person in front of him.
His reaction would have been priceless but it's a shame that he was away from town and only got back now.
Thus, Aaron is completely in the dark while everyone else in town knows about Zhen's facial features since he was in multiple spotlights due to recent events.
"Let's start!"
Aaron voiced out loud as he began to cast his magic only to be interrupted by Zhen.
"Wait, before we start fighting, are there any rules or restrictions?" Zhen remained calm when he spoke those words.
"There's no restriction and you can use any ability to win and for a victory to happen, either one of us surrender or unable to battle."
"Ok, let's swear to heaven on the bet so we cannot renegade on it," Zhen replied as he heard Aaron's word that they could use any ability.
Zhen has so many cards and tricks to get Aaron Flare under his feet.
Not to mention, the book he read has mentioned about swearing to heaven is an extremely serious promise of one's honor as they would be ruined if they failed to fulfill the commitment.
Zhen can't help but smile like a devil in his mind at how beautiful the next scene would occur.
'Getting to test my moves out and a free servant as the icing on the cake. Can't I be any luckier than that?'
Meanwhile, Aaron Flare was shocked by Zhen's mention of swearing to heaven but didn't care much as he believed he would win.
Once they both swore to heaven, Zhen knew the fight was about to begin.
As soon as someone shouted "Start", Aaron instantly cast multiple chains of magic while Zhen continued to stand still.
Zhen was analyzing Aaron's magic and determined the mana it's producing is around a peak-rank 3, it's close to becoming a rank low-rank 4 magic if he had concentrated harder.
As the flame combusted and was approaching near Zhen.
Zhen manipulated the mana in his body to turn transparent and completely focused as he closed his eyes to increase his concentration since failure means a direct hit on him.
*Whooosh*
The flame that Aaron launched passed through Zhen's body like it was air and not concrete.
*Kabooooom*
The flame that passed through Zhen's body continued to move at a fast speed and collided with a wall behind Zhen, which blasted the wall into tiny pieces of debris.
"What just happened?"
"I don't know, I just saw Aaron's flame passed through that kid's body."
"How is that even possible?"
The bootlickers that were spectating couldn't comprehend what just happened. They were all in disbelief at how Aaron's flame just went through Zhen without the impact of the combustion.
Meanwhile, Aaron was shocked and confused about how his magic didn't even hit on Zhen.
"Wait, it can't be the transparent body armor where you have to attain proficiency in the water element to transform your body."
"Oh, but I just did that so unless you want to be in denial then I can't help you."
Only a while did they understand the process but Zhen didn't care about their reaction as he started his counterattack.
'Only a fool would wait for his opponent to regain his composure.'
Zhen flashed right in front of Aaron and combusted his palm with the wind and water to churn on his stomach to make him vomit and disabled for the time being.
*Bam*
Aaron was sent flying as he couldn't block the attack in time.
"Arghhh," Aaron couldn't help but hold his stomach with both hands while clenching his tummy real hard because of the impact from Zhen.
Alas, he couldn't control the power being agitated inside of his stomach and Aaron barfed a huge disgusting load.
*Blaaaaarggghhh*
The crowd watching Aaron's vomit couldn't help but close their eyes and turn around as they feel the urge to vomit as well.
The scene was extremely disgusting that made one nauseous and the bootlickers regret watching it and wished to erase that from their memory.
While Aaron continues to vomit, Zhen doesn't care as he chants another spell which is around the high-rank 5 category on him.
"Will you admit defeat or shall I continue to launch this attack onto you." Zhen calmly spoke with a smile hanging on his face.
Even so, the crowd could only think of it as the 'devil smile' and noted to themselves to not mess with Zhen or offend him.
They don't want to feel what Aaron has experienced and looked like a fool in front of everyone.
Aaron's eye turned bloodshot after Zhen's sarcastic remark but he couldn't do anything. He had overestimated himself while underestimating his opponent.
"I-I admit defeat."
Aaron clenched his teeth and his hand turned into a fist despite how unwilling he was. He was arrogant and cocky because he has the capability to be.
It was only until now that he finally recalled his father's word.
'There's always a higher mountain in this world so never underestimate a person by their appearance. But through their conduct.'
Although Zhen doesn't know what Aaron's thinking except that he has indeed admitted defeat despite being unwilling to accept the results.
Zhen can't help but note this to himself as he has judged him far too quickly.
'Unlike Situ Sheng who is completely hopeless, this Aaron Flare knew when to admit defeat and could be saved.'
Zhen nodded his head and said, "Good, don't forget you're my servant now and don't worry, I won't make you do anything outrageous and it will be something within your capabilities."
Aaron didn't reply and simply nodded as there was no way he could get away since he swore to heaven.
"Anyway, how much gold you have on you now," Zhen asked him once Aaron got up to get away from that vomit area.
"I have around 70 gold as I didn't bring much today since I want to study at the Holy Library today," Aaron replied without knowing why Zhen asked him this question.
"Good, hand me 50 golds as I'm broke."
Zhen decided to take around 80% of his money and as he believed Aaron should be a wealthy kid since Aaron said he only brought around 70 golds.
Aaron didn't say anything and handed the gold before leaving.
He didn't want to stay here any longer as he was embarrassed about his vomiting which ruined his entire image as a prodigy.
'Sweet, this servant of mine is indeed worthy. I shall forgive your past in pursuing my Sara as who in their right mind wouldn't try to win her heart.'
Zhen happily thought about this before thinking about meeting up with Sara later on.
With the money he just took from his victory battle, Zhen preferred this kind of earning method.
'Hopefully, I get to meet more of Aaron's kind in this town. Earning money would become so easy.'
Being rich now, Zhen can treat Sara to Lily's Mirage since he promised to bring her there when he has the money.
Zhen always keeps his promise to a beautiful woman and always reneges on his promise to males.
'Don't call me shameless since I'm only staying faithful to my heart belief.' Zhen happily starts to skip in his step to meet up with Sara for some lunch.
