Besides extremely powerful protection, as long as Lis maintains his connection with the Four Elements Plane, the Shield of Four Sources will quickly regenerate even if it’s shattered. In addition, a translucent white vestment robe appeared behind Lis, slowly merging into his body. The unique arcane magic [Lis’s Sage Robe]! After making preparations, Lis did not hesitate and directly entered the Thunder Sea this time. Upon entering the Thunder Sea, Lis’s breath caught. He felt an extremely terrifying pressure descending upon him, as endless thunder pounded against the Shield of Four Sources. In an instant, Lis felt as if he were bearing the charge of countless troops all alone. Merely standing firm in this Thunder Sea was extremely difficult, let alone advancing toward the World Rune! If it were an ordinary Legendary Mage, they might have no other recourse. But Lis is different. Terrifying strength and endurance attributes endowed him with an extremely resilient body, allowing him to withstand pressure far exceeding the limits of a Legendary Mage. After adjusting his breath while standing in the Thunder Sea for a moment, Lis began to advance. Step by step, he arduously moved toward the light blue orb at the center of the Thunder Sea. The illusory vestment robe slowly flowed around Lis’s body, continuously alleviating the pressure he bore. Lis even felt that the Shield of Four Sources before him was somewhat distorted, as if it were about to shatter in the next moment. However, thanks to Lis’s persistence, he finally withstood the terrifying pressure of the thunder in the Thunder Sea, nearing the sea’s center. The entire area occupied by the Thunder Sea wasn’t actually large, covering merely a few kilometers. Yet the distance that normally took Lis only an instant to traverse felt like an eternity as he advanced step by step. The good news, however, was that he finally saw himself reaching the core area of the Thunder Sea. Not far in front of him was the light blue orb slowly rotating in midair. Just as Lis was preparing to press forward and approach the World Rune in one burst, a faint blue lightning suddenly appeared in his field of vision. The magic shield outside Lis’s [Mirror Body] avatar shattered instantaneously, and the avatar was then encased by the silver-white thunder rolling in from all sides. Without a chance to resist, the [Mirror Body] avatar was utterly destroyed. At this moment, Lis standing outside the Thunder Sea lifted his head slightly. He who had just now reacted looked somewhat astonished at the core area of the Thunder Sea, feeling a lingering fear. Everything had happened so fast just now that he hadn’t had a chance to react. Only then did Lis understand what had just happened. Official source ıs ɴovelfire.net In entering the core area of the Thunder Sea, what appeared was not only the silver-white thunder that condensed into liquid form. The light blue color was the terrifying thunder appearing near the World Rune [Thunder], This extremely terrifying thunder would haunt the core area of the Thunder Sea. And in facing such thunder, Lis stood no chance, with all defenses thoroughly destroyed. The irresistibly sharp power of the light blue thunder left an extremely profound impression on Lis. Recalling the previous experience, Lis couldn’t help but fall into silence. At least for now, Lis couldn’t think of any method to resist that light blue thunder. The protective magic combination of [Shield of Four Sources] and [Lis’s Sage Robe] was currently Lis’s most effective means of resistance against thunder attacks. Against such terrifying thunder attacks, relying on physical defense was entirely futile. The World Rune represents the most fundamental manifestation of a world rule aspect in the Gaia World. And that light blue thunder was apparently the force emitted from the World Rune [Thunder]. This left Lis with a complete sense of helplessness. Although the distance to the World Rune [Thunder] wasn’t actually far, surrounded by the Thunder Sea, it was impossible for Lis to obtain that light blue orb through distant means. According to Lis’s observations, the frequency of that light blue thunder appearing in the core area of the Thunder Sea was not low. This was the situation perceivable by the naked eye; the actual amount of light blue thunder faced might be more. Approaching the World Rune [Thunder] inherently means dealing with this light blue thunder. Without a way to take a shortcut, Lis had to resort to the old method. As a Legendary Arcanist, what to do in the face of difficulties? Of course, develop new arcane magic! However, if he wished to develop a protective arcane capable of resisting that light blue thunder, Lis’s current foundation wasn’t sufficient. For Lis, developing a spell specifically to counter thunder attacks is easy, but an ordinary Legendary Protection Arcane falls far short! Lis already mastered the Thunder Rule. [Thunder] was one of the first Transcendent Domains he had comprehended. However, currently, the Transcendent Domain [Thunder] Lis mastered had only reached the Legendary Domain stage. And this light blue thunder, although certainly not the true power possessed by the World Rune [Thunder], was undoubtedly higher than Lis’s current understanding of the [Thunder] rule. To resist the light blue thunder, Lis’s grasp of the [Thunder] rule mustn’t be too far removed from the grade of the blue thunder. Raising one’s understanding of the rules isn’t a simple task. For an ordinary Legendary Strongman, significantly enhancing their rule understanding in a short period would be unthinkable. If rule understanding could be easily elevated, there wouldn’t be so few legends embarking on the Path to Divinity. But for Lis now, it’s not an impossible feat. With mastery over the [Wisdom] domain, Lis’s speed in comprehending world rules surpasses the average legend. Moreover, currently, as long as Lis wishes, grasping other world rules isn’t a troublesome matter. As long as time is spent, Lis, who mastered the Transcendent Domain [Wisdom], encounters no significant barriers or obstacles while understanding other rules. At least, he has yet to encounter any. This is Lis’s own advantage. Apart from this, another advantage is Lis being able to directly observe the World Rune [Thunder]! Even though the current form of this World Rune is a light blue orb, upon first seeing it, Lis noticed the light blue thunder around the orb tracing chaotic and broken lines in midair. And these broken lines implicitly contain some kind of mystic charm. Upon first sight, Lis couldn’t help being drawn to them. Through these broken lines, Lis seemed to see countless world-ending thunders. Moreover, each fractured line brought Lis different insights. Seeing this situation, how could Lis not understand? These broken lines are clearly a manifestation of a part of the World Rune [Thunder]! Even just a relatively minute part of it brought Lis significant enlightenment. It was as if allowing Lis to touch upon the true essence of world rules! Just a momentary observation brought Lis many new insights into the [Thunder] rule! World Runes are indeed precious treasures coveted by even All Gods! With the aid of grasping this World Rune [Thunder] Lis is confident that it won’t take long to elevate his command over the thunder rule to a new level! Having made up his mind, Lis didn’t hesitate. He sat cross-legged in the air outside the Thunder Sea, quietly watching the intermittently disappearing broken lines around the light blue orb. Meanwhile, he extended his index finger forward, continuously tracing those unique lines. For the moment, the entire Thunder Sea returned to its previous ’calmness,’ with only the ceaseless sound of thunder and the single lonely figure remaining.
