〖Let's start. Take out the box〗Silveria ordered.
Alex nodded before bringing out the box that contains the Wyvern's heart. He then opened it and instantly powerful energy was burst from within and covered the whole cave, the energy was so powerful that it made a ripple in the air. If he had opened it outside he was sure it would have drawn all the monsters in the vicinity toward him. They would want a piece of this heart at all costs and a bloodbath will soon follow with him dying in the middle of it or worse a human passing by, maybe drawn by its energy.
Finally, he understood why Leena had warned not to open it where there were people or monsters. It was a good thing Silveria found this cave.
Shaking his head Alex focused his attention on what was inside the box, it was a heart not different from a human's heart if not for the size. It was twice the size of a human's heart and it was crystal red, emitting enticing energy.
Alex almost took a bit of it, however, he knew it would be a suicidal thing to do. Silveria must works on it before he will eat it raw. Thinking about eating raw, he was still against the idea even after feeling the enticing smell coming from the crystal heart.
''Let start and quickly get over it.''
Silveria chuckled before taking control of Alex's body. Flicking his fingers, the Wyvern's heart left the box and started floating in the air. Staring at the hovering Wyvern's heart Alex (Silveria) chuckled.
''That Leena girl is sure generous.''
The real Alex on the other side sighed. When he appraised the heart earlier all he saw was a single line. 'Wyvern's Heart.' However, currently, Silveria observed the same heart and said Leena is generous. It was to say this Wyvern's heart was somehow special. If he had advanced Appraisal he may have learned more, he thought.
Alex (Silveria) on the other hand started chanting in an obscure language as usual, however, this time his (her) chant was accompanied by hand gestures.
After a few minutes, he (she) stopped and said, ''Master it's time.''
Alex on the other side gulped as he looked at the Wyvern's heart who had become redder and crystal-like. To think he will be eating it raw, well its current appearance seemed more bearable than its previous one.
When Alex wanted to regain control of his body to eat the Wyvern's heart, he was stopped by Silveria, she was giggling.
''Fufufu, No need to be that hesitant. I was joking with you. There is no way I'll let you eat it raw. It's a prank on my part. Okay, here we go.''
Then Alex (Silveria) clapped his hands, then the crystal heart shined brightly and after the light went off, it was a red pill hovering in the air instead of the crystal heart.
''Now you can eat and beware that after taking it, you'll suffer an unbearable pain until you have ingested the energy the pill contains. For how long, even I can't say it. You have been warned.'' Alex (Silveria) warned be giving him back the control of his body.
After regaining control of his body Alex immediately took the red pill in his hand, it was hot. He then swallowed it in one gulp, it was not that he wasn't afraid of pain but because to become the strongest, he will face many hardships, and to not falter he mustn't hesitate today.
〖Good resolution but you'll need more than that to face what is about to start.〗Silveria praised before adding.
Alex did not have time to ask what she meant before,
''Gaaahhhh?"
An intense pain assaulted him. His entire body felt hot as if he had been thrown into boiling water.
As if all the cells inside his body were being turned into ash one by one. The pain traveled through his entire body.
''Gah!... when's... this going to...end...?" He asked himself because it was starting to become unbearable. He had the feeling that it has been an eternity he was suffering this intense pain that was wreaking havoc inside his body.
However, in reality only mere 60 seconds passed.
〖It's just the start.〗Silveria adds to his growing despair.
Alex didn't even have the energy to question her before the next attack begun.
He sensed a powerful force bursting from the depth of his body toward his heart.
''Argh!!"
The violent attack left him trembling as though an invisible hammer smashed his heart. Previously, he half knelt on the ground but now he was laying down clutching his heart.
''Argh!!!!!!!!!"
Alex screamed and gashed his teeth till it bleeds. He refused to close his eyes and let himself drift into sleep. The level of pain increased, every cell inside his body got destroyed, then repaired and then again destroyed, repaired...
All his five have been completely cut off, Alex felt like he was thrown into a dark space where he was observing every change happening inside his body, yet at the same time he was feeling all the pain, he could even hear the pounding of his heart.
Ba-dump! Ba-dump~
The pain increased to another level until it becomes impossible for Alex to maintain his consciousness.
〖Well, he had endured more than I thought. This Wyvern's heart is sure powerful. The benefits he will gain will be awesome.〗Silveria said after sighing.
Suddenly, Silveria heard a panicked voice, it was Gracier's voice.
[Big brother what happened to you?]
[Big brother?]
[Gracier don't worry I'm fine. Do not try to find me. I'll come back once I'm done with what I'm doing here. In the meantime use this time to train.] Alex finally responded. Gracier accepted even though she wants to check on her Big brother.
[I understand. Take care, Big brother. See you soon.] she said before cutting off the communication.
〖Ah! That was close. It's a good thing I can imitate Master's voice or else I bet that little girl will come here in flash.〗Silveria heaved a sigh of relief after taking care of Gracier. Then she decided to check on Alex's situation.
〖Let's see how he doing. What? It is still going on?〗
Silveria was really surprised, she thought it would end shortly after Alex lost consciousness but it was not the case.
Alex's unconscious did not stop whatever wrecking his body. From the other side, Silveria could only watch, helpless as purple veins bulged and pulsed across Alex's body. His heart rate was still pounding fast and his breathing turned erratic, his body temperature increased to the point where the inside of the cave become hot as well.
Silveria sighed before taking temporary control of Alex's body until he (she) jumped into the small pond located in the middle of the cave.
Back to her dimension Silveria could not help but comment.
〖This unusual. This level of pain is too much and unnatural. Sigh! There's nothing I can't do, let's wait until he woke up. I hope it won't be long.〗
When she took control of Alex's body until the pond she experienced the pain he was experiencing. It was unnatural, it was not like after taking the red pill (Wyvern's heart transformed) he will not suffer any pain but it wouldn't have lasted this long, nor it should be this violent. This Wyvern's heart was indeed higher grade and high level (the Wyvern possessing this heart) for its energy to be this violent.
Now that she thought about it, normally she should have split up the pill into two to be taken twice. It was a miscommunication on her part. Well, it has already happened, all she could do was to wait in the hopes it will not last too long until Alex woke up.
Alex's suffering continued for another two whole days.
Three days later, he finally woke up from his slumber.
