Noah could sense the black hole dissecting and studying the blue core. Understanding about Isaac's law flowed toward his mind as his organ kept unraveling that foreign existence.
It soon became clear to him that he couldn't use Isaac's law in its true form. The ability might end up hurting Noah since he was one of the existences who opposed Heaven and Earth.
Noah had to transform the law by reaching its core idea and build an ability around it. The process had to go deeper than his previous modifications. Shandal's existence had only needed a few patches to grow into a proper technique, but Isaac's skill required far more.
Isaac and Noah exited the Shadow Domain after Supreme Thief's technique ended. The light generated by the various battles shone in their vision, but both of them were too busy on other matters to enjoy that spectacle.
Noah kept his eyes closed while understanding flowed inside his mind. His sea of consciousness joined the black hole in the study and transformation of Isaac's law, and the Demonic Deduction technique also activated to help in the process.
The final technique would end up having destructive purposes, but Noah was okay with that. He had d.e.s.i.r.ed another powerful attack for a while by then, and he had finally gotten the chance to develop it.
Instead, Isaac was on the verge of falling apart. His centers of power were still under the threat of Noah's restrictions, but they didn't have much energy left anyway.
His mind was empty after the effects of Supreme Thief's technique. Thoughts and emotions had burnt when Noah had taken away the core of his existence. That center of power couldn't help him during that desperate situation.
His dantian was basically powerless. Isaac had lost the core of his existence, so his "Breath" didn't have a purpose anymore. The energy grew unstable since it lacked a proper form, but the walls of the organs managed to keep it at bay.
Only his body remained somewhat stable, but tremors ran through his flesh as the instabilities intensified. Isaac was about to fall apart, and nothing seemed able to stop the process.
However, Heaven and Earth were keeping an eye on the battle. After all, the Crystal City was the last force that carried their name on that side of the Immortal Lands. Losing it would force the rulers to rely on the troops in the sky, who required a massive amount of energy to reach the surface.
A small mass of black clouds gathered high in the sky before a single white lightning bolt fell toward the surface. The attack curved and avoided the battlefield before changing direction again and falling right at the center of Isaac's c.h.e.s.t.
Isaac also started going through a transformation as Heaven and Earth's energy spread through his figure. Noah's swords shattered under the power sweeping the expert's insides, and his organs began to work again.
A new purpose filled Isaac. The expert didn't give up his law to Heaven and Earth, but he had already established a tight connection with the rulers. They knew him thoroughly, so they had a new existence ready for him.
The battles continued to rage, but a few experts had noticed that both Noah and Isaac weren't moving. Noah was standing with his eyes closed while Isaac was on the ground, shaking. They were among the strongest existences on the entire battlefield, but they appeared completely defenseless in that situation.
A few experts believed that to be their chance to earn some glory or benefit for their force had arrived. Taking out one of those existences could tilt the scales of the battles in their favor, and they didn't hesitate to shoot downward.
Two cultivators in the eighth rank from both sides left the massive battlefield and flew downward. The four of them were in the liquid stage, but they were strong enough to threaten solid stage existences who didn't deploy any defense.
The two groups noticed each other, but they silently decided not to interfere. The cultivators from Noah's army believed in his power, and the same went for the experts in Isaac's group.
The two cultivators that aimed to take Noah down were the first to enter his range, but a massive black figure filled their vision as soon as they tried to prepare spells. Snore gave voice to a loud hiss before releasing a sea of violent dark matter that forced the experts to deploy defensive abilities.
The experts had to use their life-saving abilities and other techniques to fend off the Snore's dark matter. However, the process left them exhausted and allowed the snake to eat them in a single bite.
The other two cultivators laughed when they saw Snore eating the experts, but their expressions froze when a pulling force took control of their actions. They had only neared Isaac, but a power similar to a domain suppressed their laws and brought them closer to the expert.
The two cultivators couldn't do anything to oppose that pulling force. Their life-saving techniques activated, but the pressure in the area shattered them in an instant. The experts continued to descend toward Isaac, and painful cries soon escaped from their mouths when their faces began to separate from their skulls.
The pulling force tore the experts' faces apart and brought them closer to Isaac. Those gory body parts disappeared when they touched his skin. It seemed that his new existence could feed on those materials.
The two experts fell on the ground after the process. Their eyes were empty, and their centers of power soon started to disperse their energy. It had only taken one attack to kill both of them.
Isaac stopped trembling at that point. Sparks ran through his body as he straightened his position and began to inspect the changes in his existence.
Heaven and Earth didn't only improve his cultivation level. They had also expanded his existence and added features meant to counter his opponent. Moreover, sparks still ran through his body. It seemed that his element had changed after that transformation.
Isaac soon moved his gaze on Noah, who was still busy taking care of his new ability. Snore, Duanlong, Night, and black roots appeared in front of him when they sensed the expert's dangerous attention. They were ready to protect their master even if their power alone clearly weren't enough to fend him off.
"It's ok," Noah suddenly said as he made his way through his companions.
His cultivation level fell and returned to its normal state. Even the companions' power went back to the middle tier. Noah had deactivated the effects of his ambition to suffer lighter drawbacks, but Isaac could only smile at that sight.
"Are you crazy?" Isaac laughed while raising his hand to materialize his stick. "Heaven and Earth have given me a stronger law that doesn't suffer from your power. You will have no advantage over me, but you still decided to withdraw your law."
"What's the point of a law when you have given me the most powerful weapon in the world," Noah scoffed before exploding into a crazy laugh. "You have founded an ability on your kills, and you even let me steal it. Do you have any idea of how many experts I've killed?"
The entire surface of the region shattered after Noah finished his line. A massive pressure had suddenly come out of his figure, and Isaac's expression froze at that sight.
