Jacob frowned when he saw 'Don't worry' and sternly questioned, "What do you mean by 'don't worry'?"
"Hoh, did I say something?" These words appeared the next moment.
Jacob's expression fell the moment he read those words, and he knew this book was again messing with him. However, he suddenly felt like sleeping, and he instantly knew the hunger was acting up.
Although he had acquired the fire wyvern's endurance, but he couldn't just sleep for hundreds of years to sustain himself.
"Stop messing around and tell me how this endurance works exactly!" Jacob sternly questioned.
"Tsk, tsk, what a simple question, sigh… I have to tell you everything in the end. The Endurance of this Wyvern will raise your Endurance to the level of a Unique Rank Wyvern.
"Your human body will no longer waste any extra energy as it did before, and all required energy to move your body or do tasks or fighting has been decreased by 90% with your current level.
"But you will feel the urge to sleep all the time if you're about to run out of energy in your body. It's a sign of hibernation, but unlike Wyvern, which can absorb the energy from the environment to recover while in hibernation, you will sleep to death because you didn't have such an ability.
"So, I suggest you won't fall asleep without an empty stomach, hahaha… Lastly, the endurance will be decreased as your power rises until you surpass the unique rank.
"This is the only flaw of Physical Aspects like endurance, agility, strength, magic talent, and so on. They are not yours, so they will become useless in time as you continue to increase your prowess.
"So, I strongly suggest you won't get used to them because they will not increase like abilities and will lose their effect with time. If you have killed a peak epic rank wyvern, then your endurance will be of legendary rank Wyvern, what a pity, right…hehehe."
Jacob felt somewhat regretful after this revelation, "So to say, the physical aspect will be like temporary boosts while the abilities can increase with my own power?"
"Exactly. But not all the physical aspect is like this like if you awake a legendary creature's eyes which can grow with magic or evolve with some other materials, you will naturally inherit that aspect as well.
"Lastly, if you awake the same kind of physical aspect again that you already had, it will either override the old one or not activate at all.
"Like if you awake the endurance aspect of some other species again, if it's stronger than the Fire Wyvern Unique Rank Endurance, it will instantly override it. While if that aspect is weaker, then it won't be active at all!"
Jacob's eyes shimmered in understanding after reading this, 'So, I don't have to worry about replacing the useless aspect at all!'
Although the physical aspect was somewhat weak in comparison to the ability, if he got an overpowered physical aspect, then it was even more valuable than an ability that would only increase with his own power.
After asking some more questions, he closed the book, and without hesitation, he started to eat like crazy. He ate until he no longer felt sleepy anymore, and he could now even feel his body getting stronger with every beast he consumed at a terrifying pace.
Another week passed like this, and almost all the meat in Jacob's pendant that he had accumulated had gone. But Jacob still had this lingering feeling of sleepiness, but not like before when he felt he wouldn't be able to wake if he feels into asleep.
It was more like a sleep where he would stop using his energy and fall into a standby-like state. After some experiments, Jacob can easily feel into this state and awake within a moment's notice.
'It seemed I had to eat tier-6 extraordinary meat if I wanted to complete my Epic-Tier-1 body. But I still haven't any clue about magic. What a waste…' He thought bitterly.
Jacob was already strong enough to kill anyone in the rare plains, but he still hadn't had a trace of magic which was his only regret now. Still, he knew this thing couldn't be hurried or forced.
So, without wasting more time, Jacob continues his journey toward the dark city as well as continues his study of Rune Artificer. He was already at the Senior Grandmaster Rune Artificer Rank part and only the Elder Grandmaster Rune Artificer Rank away from remembering the entire Magic Rune Encyclopedia.
Although he won't be a true Elder Grandmaster Rune Artificer, but he would be as knowledgeable as one. When he had the time, he would practice as well.
He was now in the magic beast forest's inner region, and anyone with a sane mind would try their best to hide their presence since this place was filled with vicious beasts.
But Jacob walks like he owns the place while completely focusing on his star watch. After he awakens the Wyvern Unique Rank endurance, his mental endurance is enhanced, as well as his physical endurance.
The magic beast attacks become more frequent as they all think of Jacob as easy prey.
But no matter what kind of ambush they performed, whether it was a physical attack from close quarters or a magic attack from shadows, Jacob always managed to block it in the nick of time and kill them before they even had the chance to react.
This way, Jacob also continued to eat while he visibly felt he was getting closer and closer to acquiring an Epic-Tier-1 physique, and the effort he had to put into killing those magic beasts was also becoming lower.
Two days later, after Jacob continued his journey, he finally remembered the entire Magic Rune Encyclopedia!
But he didn't even waste a moment before he opened the Philosopher's Language, which was the language of Alchemy.
After comprehending the Rune Language, Jacob found that the Philosopher Language's difficulty decreased exceptionally, or it was the case because he had some understanding of this language before.
Whichever the case was, it only took him half a day to completely comprehend the type-0 Philosopher's Language.
Jacob also realized that the language he learned in the common plains was nothing but a fragment of type-0 Philosopher's Language!
