One person and one machine, both remained focused only on their opponent! The two giants, possessing the most elite strength on this planet, now fought like ordinary people, wildly trading blows! At their level of skill, superficial moves were nothing but trivial tricks. What mattered was energy control, the superiority of algorithms, the frequency of the spirit, the resilience of willpower... and other hard indicators. And in these aspects, the "King" considered itself definitely superior to Su Yu. Because Su Yu, after all, was fundamentally of the Third Rank, with no experience in using Fourth Rank power. However, this was merely wishful thinking on the "King"’s part. After thousands of punches exchanged with it, Su Yu showed no sign of being at a disadvantage; in fact, he grew stronger the longer he fought! Because when Su Yu fought the "King," he inadvertently recalled the details of energy flows and algorithm optimizations inside the mecha, observed when the Radiant Mecha previously extracted the Hell Furnace. Before, Su Yu couldn’t understand those details at all, but after transforming into the Light-Cast Giant and engaging the "King," he started to grasp some of them. And the more intensive the battle became, the more he understood! The more adept he felt! "So, those technical details need such a body to be fully utilized!" "Earlier, the Radiant Mecha must have intended for me to clearly see those details." "Some of the details are likely unknown even to the ’King,’ after all, it was never truly acknowledged by the Radiant Mecha." Upon realizing this change, Su Yu was filled with immense joy. His thoughts flickered wildly, and the radiant power on his fists grew stronger and stronger! The "King" naturally noticed this detail, feeling both shocked and wrathful. It too roared and increased its power, growing stronger with each clash against Su Yu! The battle grew even more intense! Its essence of power derived strength from pain! This pain was not just from the suffering of other beings. It seemed the "King’s" own pain also increased its power, and the effect seemed even better! However, under normal circumstances, the "King" would not willingly inflict pain on itself. Using the Power of Pain did not mean it enjoyed suffering. Normal beings prefer joy and dislike pain. Although the King was twisted, it was still normal in this aspect and wouldn’t exchange its own suffering for power. Otherwise, even if it gained power, living immersed in endless pain held no meaning. But now, it was in such pain! It hadn’t tasted such agony in millennia, pain beyond its control. This pain wasn’t something it desired; it was brought upon it by Su Yu. Everything it had pursued for ten thousand years was destroyed and taken by Su Yu within minutes. Now, Su Yu was using this power to battle it fiercely, trying to kill it, and use it as a component for a ritual! How could it endure this? How could it not be in pain? This was too much bullying! At this moment, the "King" even felt a bit aggrieved. Thinking about it made the pain in its heart even deeper. It, the King of the Mechanical Race, nearly a fifth-rank super being, forced into such a situation by Su Yu, a mere third-ranked human. When it thought about this fact, it felt on the verge of madness. Thus, its Power of Pain naturally surged, becoming stronger and stronger with the fight. Su Yu quickly noticed the change in the "King," feeling troubled. The "King" had been intensely provoked and was on the brink of madness. If it continued to grow, would it directly break through to the Fifth Rank? The "King" was originally top-tier at the Fourth Rank, capable of attempting to break into the Fifth Rank. But apparently, ascending to the Fifth Rank was exceedingly difficult; it had tried for millennia without success, which was why it sought the power of the Radiant Mecha. Now, had Su Yu forced it to its limits, ready to break free from constraints and ascend to the Fifth Rank? If that happened, it would mean Su Yu had fulfilled its wish. "That won’t do! You want to ascend? I’ll kill you first!" Su Yu hardened his resolve, and the power of radiance intensified further! In that instant, the entire Manifestation Space flooded with light, suppressing the "King’s" dark power of pain! The power Su Yu transformed into seemed infinite, constantly rising, with no end in sight. The "King" roared wildly, but under Su Yu’s fierce assault, signs of its breakthrough seemed suppressed. This slightly calmed Su Yu’s heart, yet puzzled him. Where exactly did such power come from? Is it considered borrowed power? If he used this state to actually kill the "King," could he complete the ritual? The most critical question was, what if this power suddenly ran out? Forget completing the ritual, he might instantly be killed by the "King"! No one could answer this question. The Mechanical God had long been silent, busy maintaining the stability of the Manifestation Space, unable to aid Su Yu. Even if the Mechanical God was still around, with its insulative nature towards Spiritual Energy, it likely couldn’t provide any insight. Su Yu didn’t rely on the Mechanical God, instead, he devoted himself to figuring out the principle. "Firstly, the power couldn’t have come from nowhere." "I also didn’t feel any external power being infused into me, nor did it come from the subspace." Fresh chapters posted on 𝓷𝓸𝓿𝓮𝓵•𝓯𝓲𝓻𝓮•𝓷𝓮𝓽 "So... this light power of mine now seems to be my own power?" Su Yu, after analyzing, surprisingly discovered this terrifying power was actually his own? This was somewhat unbelievable. How did he not know he had such strength? If he had known he could transform into a Light-Cast Giant and suppress the Fourth-Order Top "King," why go through so much effort? "Could it be that I’m harboring the bloodline of some cosmic giant, awakening at the critical moment?" "Or was I some ancient powerhouse in a past life, now truly revived?" At that moment, Su Yu even considered such strange thoughts, really doubting if he was some ancient powerhouse reborn. But Su Yu quickly dismissed the unreliable notion. Now was not the time for idle thinking during the war. Switching his mindset, Su Yu soon thought of another possibility: "After eliminating all possibilities, then it must be..." "The power of faith and intent!" Su Yu had known all along he possessed a powerful force! Since Su Yu’s ascension to Seven Stars, this power had always accompanied him. Su Yu had saved millions of humans, tamed a large number of Radiation Beasts, and even demons from the depths of subspace. These humans, Radiation Beasts, and demons constantly provided Su Yu with the power of faith and trust. While many weren’t Su Yu’s believers, he could always sense that sense of reverence and trustful intent. Yet Su Yu had always found it difficult to directly utilize this power, unable to transform it into combat strength. Instead, the Profession Panel could convert this power of faith into professional experience, helping Su Yu rapidly upgrade. After ascending to Seven Stars, Su Yu barely trained and hardly "leveled up by fighting," relying predominantly on this effortless experience to upgrade. To have elevated Su Yu to his current level in such a short time highlighted the power’s strength. Moreover, now it seemed this power wasn’t just for upgrading but also for fighting! By using the Radiant Blueprint to transform into the Light-Cast Giant, Su Yu finally unearthed this power from deep within his body, turning it into the endless radiance filling him! "This power isn’t just faith but includes gratitude, joy, hope, reverence..." "These positive emotions constitute my current self; its essence is extremely powerful! It was always lurking deep within my body, unearthed by the Radiant Blueprint!" After figuring all of this out, Su Yu felt exceedingly excited. Because this power was not external but truly his own. It was something he had amassed through his struggles! It belonged to him and could not be taken by anyone! Using this power to defeat the "King" would not be considered borrowed power! It would surely complete the ritual! With this understanding, the radiance emanating from Su Yu instantly glowed even brighter. "Speaking of which, this power is indeed honest and open. In a world ravaged by evil gods, to have such a bright power is truly rare." "Radiant Mecha, truly lives up to its name! It’s just like the sun!" "This power shall be called the Power of Sunshine!"
