Ten thousand I am across the heavens

Although Black City had a more powerful background and retained a certain obsession during the transformation, despite being told he had to persevere, he ultimately couldn't withstand the sensory stimulation that exceeded human limits. His perception was completely distorted in a short period of time.

This also meant the eldest son had obtained a trump card. He began a comprehensive transformation of the man's entire body. The transformation process went quite smoothly. Many previous technological conjectures were validated in his case, further confirming the eldest son's understanding of this special life form of his ancestors. Based on this understanding, Black City was also implanted with a perfectly suited immortal Gu during the transformation.

After being modified, it has gained considerable potential, and can use this seventh-level Gu worm as the core to construct a powerful immortal technique, posing a certain threat to and restraining eighth-level immortals.

The eldest son had already learned of the existence of battlefield killing moves. Such moves required defeating the caster to truly escape; at least, their current spatial abilities weren't enough to directly break free from the blockade. Therefore, they needed to develop a sufficiently powerful killing move, one that, even after dispersing into a group of individuals, would still possess the strength to contend with an eighth-rank expert. At the very least, it needed to be able to stall for a long time, until the opponent had exhausted their resources.

It's not necessary to win; simply wearing down the opponent until they're too exhausted to continue is enough. Even eighth-level powerhouses have their limits. If they expend too much energy in a battle that doesn't involve their own lives, they will choose to retreat.

Black City and the other immortals were essentially used as bait, cannon fodder, thrown down by him. He was willing to sacrifice some of his immortal Gu, as long as he could use this opportunity to lure the immortals out, buy them time, and allow the ultimate life forms split from his eldest son to escape. These losses would be worthwhile. With his current knowledge, it wouldn't be too difficult for him to recreate these and rise again.

On the battlefield, its size had been reduced to barely more than a skyscraper. This was now a fraction of its original size. At this stage, everyone could recognize that the eldest son had entered an unprecedented period of weakness, and they wanted to seize this opportunity to take everything from Changxu. This was the shared thought of all the hidden masters: if they could grasp this opportunity, they might be able to defy fate and become legends etched in history.

The underground base had reached a point of near exhaustion. The underground vacuum pipe network had been completely dismantled, broken into several pieces, and could only operate independently in each section. The main combat force had also suffered heavy losses, with casualties reaching 90%, although a significant portion of these casualties were simply due to injuries that rendered them incapable of fighting. After being rescued in the rear, they were still capable of returning to the battlefield. Nevertheless, this level of casualties was still extremely alarming.

The bases on the ground were relatively well-preserved because they had been doing everything in their power to protect these energy cores and ensure their maximum output. Even so, due to the heavy casualties among the frontline soldiers, the strength of the various legions was still significantly reduced. But it was still a miracle. With these mortals as the main force, they actually managed to bring a legendary creature to the brink of death. However, even in its near-death state, the eldest son was still incredibly powerful, and its soul was not significantly obliterated. It still possessed a dominant and suppressive force.

At this moment, as the eldest son unleashed its final power, the massive creature, now only the size of a skyscraper, exploded, like a firework bursting amidst a towering peak. Hundreds upon hundreds of humanoid beings flew in all directions, using the initial velocity from the explosion to escape. With thousands fleeing simultaneously, interception was extremely difficult. The underground base released missiles that had been prepared beforehand, specifically for interception, but these individuals possessed extraordinary strength. The missiles, equipped with remarkably high artificial intelligence, completely missed their targets after being released. Instead, many were scanned and locked onto by long-range attacks before impact, and then annihilated with a single shot.

In mid-air, a seemingly ordinary split individual, wielding a bio-material longsword, effortlessly sliced ​​a distant missile in two with a single strike. The sword energy was barely perceptible; it was unclear whether the energy was invisible or simply too fast. Other missiles were largely ineffective, and even those that did hit their targets were largely unaffected. Furthermore, the specialized attacks targeting the eldest son's weaknesses rarely caused any real damage; the disparity in strength between the two was too great, and the superior individual's power rendered it virtually immune to these attacks.

However, not all the split entities were unscathed. Faced with the deadly attacks of war and legion assaults, some were unlucky enough to be reduced to ashes on the spot. But there were only three such individuals in total, and they were eliminated by the combined attacks of the three legions, which currently have the best-preserved strength.

The escaped individuals paid little attention to the underground base's combat capabilities. They had changed their fighting style; if they were to engage the underground base head-on, they could likely turn the tide by strategically destroying the energy cores. However, a prolonged battle here was not their objective. Their current goal was to escape, and the underground base couldn't simultaneously intercept so many powerful individuals. When the eldest son was still a unified entity, they could be forcibly stopped by the barrier. When they were still individuals, breaking small openings in the barrier was effortless. The outside world didn't have such extreme temperatures. After leaving, they could quickly absorb and assimilate the surrounding matter, converting it into part of themselves, further enhancing their combat power. Their combat endurance would also be much higher, making a prolonged battle completely unnecessary.

As these individual powerful beings were blasted out by the explosion, the immortals who had rushed forward to take advantage of the situation found themselves clashing with these incredibly powerful split entities.

A sixth-level immortal, who had been patiently waiting until now to make his move, unleashed his signature killing move. A Gu worm, no bigger than a palm, flew out from his body. Resembling a praying mantis, it wielded its pair of scythes and slashed at the eldest son's split form. This was also a slave path expert, but unlike ordinary slave path experts, he chose not to control massive herds of beasts, but to cultivate a single powerful beast. Then, he completely fused this beast with the Gu worm within his body, transforming it into a powerful trump card for his battles. It's somewhat like a summoner. This cultivation method is not common, but it's not actually that difficult. In head-on battles, it can sometimes even unleash power stronger than a normal expert. After all, there are some desperate moves that one wouldn't dare use personally, but when controlling a summoned beast, it doesn't matter.

The mantis, with strength comparable to a sixth-tier powerhouse, swung its pair of scythes, unleashing terrifying crisscrossing slashes despite the surrounding vacuum. The attacks swept across like sword energy.

He could sense his opponent's aura; they were only at the peak of the fifth rank, not yet at the immortal level. Against an opponent of this level, he should have been able to kill them instantly. But the humanoid creature opposite him merely raised an arm, and an invisible barrier spread out from it. Cross-shaped attacks struck the barrier, creating hexagonal ripples that failed to penetrate it. "How is this possible? How can a fifth-rank cultivator possess such strength?" The soul strength of a slave cultivator is often higher than that of an ordinary cultivator. After his initial surprise, he calmed down and finally understood what the invisible barrier was. It was a materialized soul force field. The eldest son's soul power was simply too strong; even a small portion distributed among these fragments far surpassed the power of ordinary soul cultivators.

This layer of soul power can even form a solid barrier in physical confrontations.

However, a major advantage of a powerful slave cultivator lies in their ability to control multiple targets in combat. While not the type to tame large numbers of wild beasts, they still cultivate more than one Gu worm. Another Gu worm, resembling a bee, simultaneously flew out, swiftly launching an attack from another direction. Its speed was so great that ordinary people couldn't react. Its highly venomous stinger pointed directly at its target. Once struck by this poisonous stinger with its powerful armor-piercing ability, even an immortal would lose their fighting ability for a short time. At this moment, the soul barrier's defense was activated, and an attack from another direction would surely succeed. This was a tactic they frequently employed: having the mantis launch a strong frontal assault, followed by a sneak attack from behind by the bee. The tactic, though simple, was often highly effective.

The eldest son, in his March form, seemed completely unconcerned about the sneak attack from behind. He allowed the venomous tail sting to strike him, and in that instant, he threw a punch. This punch, unleashed with the sound of wind and thunder, seemed to cause the entire space to tremble. Such immense force was approaching that of a True Immortal.

The bee had no chance to struggle at all. Its body was instantly pulverized by the terrifying force, dissipating into dust like smoke. The immortal who had intercepted it coughed up a mouthful of blood. Although this wasn't his natal Gu, the severe injury still affected him. Fortunately, the attack had hit its mark, and the poison had entered the enemy's body. Now, all that was left was to wait for him to die on the spot.

However, things are clearly not that simple. Even though this is just a split offspring of the eldest son, his control over his body is almost perfect, unlike that of humans.

Human senses are relatively simple. While we can see, hear, and touch everything in the outside world, our ability to control our own internal organs is limited. When we don't need a fever or an allergic reaction, we can't control our immune system. We can't stop our digestive system when we don't want to digest food. This makes humans often lack resistance to toxins entering the body. If a highly toxic substance is injected, the poisoned limb often needs to be amputated immediately to save a life.

However, if you have sufficient control over your body, you can actually withstand the damage from potent toxins almost unharmed simply by sealing off blood vessels. This prevents toxins from spreading through the bloodstream and allows the toxic blood to be expelled directly from the body.

The toxins released by immortals are certainly much more difficult to deal with than ordinary toxins, but the principle of poison's action is ultimately similar. It doesn't take effect instantly upon entering the body. Rather, it needs to spread throughout the body through some medium to become effective, or to reach certain vital organs and damage them before it can have an effect.

The immortal's toxins not only damage the normal human organs, but also directly destroy the orifices. This is the most terrifying aspect of the poison. Ordinary people cannot accurately control the flow of their true essence. No matter how hard they try to control it, some of it will flow back to their source sea. The poison will destroy the orifices through this medium, instantly rendering the Gu Master unable to fight.

However, the eldest son's control over his body was almost at the molecular level, even deeper than the cellular level. He could even subjectively control the physiological activities of his cells. This meant that biological toxins were completely meaningless to him. After being injected into his body, he could simply not absorb them, and toxins at the transcendental level, limited by his precise control over his own power, were also difficult to truly spread. We saw a stream of black liquid spurt from his body; that was the toxin that had just been injected into him. Even though it stayed inside him for a while, even though the toxin actively tried to spread, trying to break through his blood vessels, spread throughout his body, try to merge into his true essence, and directly destroy his empty shell along the meridians, it ultimately failed. Instead, it was surrounded and expelled by cells from all directions.

The split entity clearly didn't have time to waste on the trust placed in front of it, and even in a one-on-one fight, it wasn't confident of victory. After all, it was only at the peak of the fifth rank. So, after withstanding two attacks, it decisively turned and ran, unfurling wings formed from a mass of flesh and blood and flying at high speed. Although there was no air, the flapping of its wings seemed to utilize some spatial principle, still granting it extremely high acceleration. But before it could fly very far, the Five Elements Mage, who had been accumulating strength all along, finally made his move.

"You will all stay here today!"
