Ray looked at the red panel and made an almost instant decision: to advance the skill.
[Genetic Synchronisation (Awakening IV)] - [Genetic Synchronisation (Awakening V)]
Immediately, Ray felt a large chunk of his mental energy drain from his body.
"Hmm?" He frowned and checked the system.
"Eh, what?"
Ray had advanced the skill without even looking, and now he realised he had lost a hundred thousand mutation energy.
When he checked the skill, it could no longer be advanced. This realisation hit him hard.
"I can't fully upgrade my S-class skill," Ray muttered with a bitter smile.
But this wasn't a problem for Ray. All he needed to do was hunt more undead, which were plentiful after the next wave of mutational energy hit, mutation energy became incredibly dense.
The undead became even more abundant.
Although it took some effort to accumulate mutation energy, Ray could still do it with ease, so he wasn't too worried.
With this in mind, Ray looked at his fully advanced A-class skill, now at the pinnacle of power, for which he had painfully spent one hundred thousand mutation energy.
Ray glanced at it, and his pupils almost froze on the spot...
...
With the second tide of mutation energy appearing on Earth, everything underwent a rapid and instant transformation.
All things in nature changed, and beings that weren't previously infected began slowly becoming infected one by one as the mutation energy in the air grew denser.
Too bad, one cannot absorb mutation energy from the air; this wasn't a fantasy world of cultivation!
On one particular continent, where the highest concentration of lush forest covered the entire area, some parts remained unexplored and hidden from human civilization.
Where the Nile ran through, and creatures were abundant.
Unfortunately, with the descent of the Apocalypse, everything changed, and all the lush forests disappeared.
Some of the people did adapt to the mutation energy and became Awakeners.
In fact, these Awakeners were naturally actually much stronger than the other average Awakeners from other continents.
However, the undead beings were even more numerous here and there, and their rapid evolution caused the entire population of this continent to become desolate, teetering on the brink of extinction.
Only Awakened humans were left alive, but even they were living in hiding from the undead.
Now, this entire continent was almost entirely inhabited by terrifying undead.
In this continent, a small plane slowly flew in before swiftly landing in this almost netherland with accuracy.
As the door to the plane opened, a golden-haired woman with a blindfold slowly walked out, and behind her, numerous people also stepped out of the plane.
There were different types of people behind her, with two on her left and two on her right, but the most common thing about them was that they naturally exuded a sense of pressure simply by standing there.
The pressure was enough to make a person sweat just from their mere presence. They were all S-class Awakeners!
"Sheer, why are we here?" Clay tugged at his cowboy hat and looked around the place.
She paused and looked at everyone. "We will be rescuing both Sibley and Natalia, but that will come later, after we obtain the weapon to deal with him."
Everyone silently followed now, not a single person speaking.
"I must rule this world." While they were walking, she tightened her fist in the hidden sleeve until it was wounded, and blood gushed out.
"This is the wish of my Leon..."
As she thought of that memory, a small tear almost escaped through the blindfold, but she managed to keep it hidden enough not to be noticed.
Blood seemed to appear in her hand, materialising and disappearing as if it were a mere illusion.
But she knew that this was just an illusion—a trauma from her previous life and the lives she had taken personally in this one.
...
"Hmm?"
Ray looked at the attributes of his skill with a blissful expression on his face.
First of all, he could bond with an infinite number of people easily, as long as he had a certain affinity and the other party was willing, of course.
This meant he could potentially bind with thousands of people and gain their power. If they were Awakened, he would also gain their skills permanently, without any cooldown of twenty-four hours.
If that wasn't enough, Ray could also gain extra power from those exceptionally close to him and gain more than their own power when he used Gene Synchronisation to bind them.
This could undoubtedly be helpful for Ray, even currently at his Celestial level, not to mention that he could also duplicate almost half of his entire attributes and skills and share them, which would undoubtedly protect his women as much as possible.
With almost half his power, even solving Level Three Undead would not be a problem, not to mention his power would rapidly grow in the future.
Then came a system of his own that made sharing mutation energy possible.
As long as Ray had done Gene Synchronisation with them, he could take their mutation energy or even give them his own mutation energy.
Overall, all his methods had rapidly improved just from this A-class skill.
"Hmm?"
His mutation energy had dropped to just over three thousand nine hundred.
This was a significant amount for him, and Ray could be sure that he could very well upgrade at least three A-class skills if he had it.
But the prompt in front of him said otherwise.
[Ding! You have five thousand mutation energy. Do you wish to advance your skill: Overlord of the Sky (pseudo S-class) from Awakening III to Awakening IV?]
"Five thousand mutation energy?"
Ray decided to advance his skill, and immediately warm energy flowed through his body, with information rapidly appearing in his mind from his very own Gene.
This information was equally complex as from the Gene Synchronisation however Ray could quickly discern that there was extra information as well.
"Lightning Arts?"
Ray looked at his surroundings and immediately used the technique he had gained from the information. The world around him shifted, and small bits and pieces of static energy appeared in front of him.
All electrical energy could now be visible in front of Ray and not a single electrical energy could hide from his eyes.
Ignoring this, Ray looked at the cost of mutation energy for the next advancement and almost flipped out on the spot...
Three hundred thousand mutation energy!
