Chapter 358: Chapter 170 Night Demon_2, The purity of Level 2 Crystal Cores is 55%. By synthesizing two crystal cores, the purity remains at 10%., So the purity of these 13 crystal cores is 10%, and when converted to his body’s impurity rate, it’s 0.1%!, Now Wang Tao has 1.1% of internal impurity… So, he thought he could first fuse 9 Omnipotent Crystal Cores to raise the internal impurities to 2%, and then use two Cleansing Potions to remove all the impurities inside!, He had been enduring this small amount of internal impurity in his body for quite a while now., When the internal impurities first appeared, he felt somewhat uncomfortable. Although it didn’t affect his combat performance, it was still annoying., But there was no choice at the time, he had to fuse Ascension crystal cores, and then the internal impurities accumulated to 2.2%…, Luckily, when he ascended to Level Two, the internal impurities were reduced by half, and now only 1.1% were left., Back then, he considered that he had only five Cleansing Potions, and each potion could remove 1% of internal impurities. For 1.1% impurity, using one bottle wouldn’t be enough, and two would be a waste…, So he had been putting it off until now., Finally, he had the chance to remove them all., “But… I don’t know which Special Ability the Omnipotent Crystal Cores will level up…”, Wang Tao looked at his current three abilities., Level 2 Shockwave, Level 2 Precision Shooting, Level 2 Barrier., If possible, Wang Tao naturally hoped that the Omnipotent Crystal Cores would upgrade Barrier., Because Barrier was a new Superpower synthesized from both the “Toughness” and “Self-healing” abilities., Zombies seemed unable to drop Barrier Abilities… If Wang Tao wanted to upgrade, he could only rely on Omnipotent Crystal Cores., But when fusing Omnipotent Crystal Cores, the level-up was random among the several abilities he had. He couldn’t control which one would be upgraded., Unless he first leveled up Shockwave and Precision Shooting to 10, the max level for Level Two. In that case, the Omnipotent Crystal Cores could only be used to upgrade Barrier., Unfortunately, Wang Tao currently had only one Level 2 shockwave crystal nucleus at hand, and even worse, he didn’t have a single Level 2 Precision Shooting crystal nucleus… so he couldn’t upgrade these two Special Abilities first., Wang Tao instinctively glanced at his special energy again., This special energy could only extract and fuse abilities but couldn’t determine the priority of upgrades for the Omnipotent Crystal Cores—, Wait a minute!, Wang Tao suddenly paused, then quickly looked at the description of special energy again., Current Special Energy: 7740, Extraction abilities: Turn a mastered ability into a crystal core of the current level. Extracting a Level 1 Special Ability consumes 1000 special energy; extracting Level 2 Ability consumes 5000 special energy; extracting Level 3 Ability consumes 30000 special energy, Ability Fusion: Fuse two learned abilities of the same level. If the fusion is successful, the ability will have the characteristics of both, and the Special Ability Level will be the average of both. If the fusion fails, the main ability remains, and the Secondary Ability disappears. Fusion of Level 1 Special Ability consumes 1000 special energy; Fusion of Level 2 Ability consumes 5000 special energy; Fusion of Level 3 Ability consumes 30000 special energy, Wang Tao had used the ability fusion before, but this time he focused on the extraction ability., “Turn a mastered ability into a crystal core of the current level… doesn’t that mean I can temporarily turn my Shockwave and Precision Shooting abilities into crystal cores, leaving only my Barrier Ability, and then use the Omnipotent Crystal Cores to directly target Barrier Ability for an upgrade?”, Wang Tao’s eyes lit up., He seemed to have stumbled upon something terrific!, However, he did not have enough special energy to extract both Shockwave and Precision Shooting at the moment, he could only extract one., But by extracting only one ability, he would only increase the probability of upgrading the Barrier Ability from one out of three to one out of two, a rate that Wang Tao still found unsatisfactory…, And as for extraction, Wang Tao thought of a crucial point—, “Since I can turn a learned ability into a crystal core of the ‘current level,’ could I not learn a Level 1 Ability, then use an Ascension crystal core to upgrade it to Level 2, and extract this Level 2 crystal core… wouldn’t I have a 100% pure Level 2 Epic Crystal Core?”, Wang Tao was surprised by his own brainstorm, but after thinking it through, it seemed feasible?, Under normal circumstances, if he wanted a 100% pure Level 2 Epic Crystal Core, he would need to synthesize three Level 2 Crystal Cores. But that would be too wasteful., Using this method, the cost for him to obtain a 100% pure Level 2 crystal core would be “10 Level 1 Crystal Cores” plus “1 Ascension crystal core” plus “5000 special energy”—because to extract this Level 2 crystal core, he needed special energy., Looking at it this way, even if it costs 5000 special energy, it would be worth it overall, as aside from the Ascension crystal core, no other Level 2 crystal cores were needed!, Wang Tao had initially planned to fuse 9 Omnipotent Crystal Cores and then use two Cleansing Potions to remove the body’s impurities. But now he had changed his mind., If he fused Omnipotent Crystal Cores now, the ability level might be added to Shockwave and Precision Shooting., It would be better to save up 10000 special energy first, extract both Shockwave and Precision Shooting, and then use the Omnipotent Crystal Cores to upgrade Barrier., After Barrier reached 10, he would start fusing Level 1 Shockwave, Precision Shooting crystal cores to ascend them to Level 2, and then extract those Level 2 Special Abilities., Finally, once he had collected 10 Level 2 Shockwave and Precision Shooting crystal cores, he would be able to level up all three of his abilities to 10!
