Ten thousand I am across the heavens

From the eldest son's perspective, his decision was actually reasonable. Compared to the underground base, these people who knew nothing about him were much easier to deal with. Although their individual strength was much greater, their vigilance towards the eldest son and their understanding of his intelligence were far inferior.

This meant that the eldest son could capture them with minimal energy expenditure and losses, and the rewards for capturing them far outweighed those for capturing ordinary soldiers in the underground base. Any one of them could be trained into a super soldier. If these smaller foes had appeared earlier, perhaps the eldest son wouldn't have been forced into such a dire situation.

Since these blood packs can even replenish the eldest son's current energy, making him stronger when attacked, why not actively lure them out to attack? True eighth-rank experts could indeed pose a threat, but after he's figured out all sorts of human techniques, those so-called seventh-rank experts are no threat to him. In fact, if they don't understand him well enough, or if they're too careless, they'll simply perish within his body, becoming part of his nourishment.

Therefore, when confronting the underground base, he deliberately displayed weaker strength. By feigning weakness, he made it difficult for other forces, besides the underground base, to detect his true state during reconnaissance. His apparent weakening deceived many, creating an opportunity for a surprise attack. As it turned out, the eldest son's performance was effective, fooling several people, including those in Black City.

The fact that the Black Prison was almost destroyed back then did leave a deep psychological scar on this guy. But now is the time to kick a man when he's down, or at least that's what he thinks, so he didn't hesitate to take advantage of his eldest son's weakest moment and use the newly repaired Black Prison to suppress him.

The Immortal Gu House, ultimately, proved too powerful for the eldest son. Despite various attacks, it withstood the onslaught and crashed down. It wasn't that the eldest son lacked the ability to destroy it. He had encountered similar entities before, such as the underground trains developed by the underground base, one of which was an Immortal Gu House. This train was incredibly fast, and its internal space expanded to house dozens of energy cores, making it an impenetrable, high-speed underground fortress. With such a thing, the underground base's energy supply was always guaranteed, and he didn't need to worry about reaching the battlefield, as it was thick-skinned, possessed spatial abilities, and wasn't easily destroyed. However, the eldest son had managed to pinpoint its location several times and launch attacks. While the initial attacks only caused superficial damage, as he became more familiar with its structure and organization, subsequent attacks became increasingly dangerous. If it weren't for the Immortal Gu House's extraordinary speed, allowing it to evade attacks, serious consequences would likely have ensued.

Although the Black Prison has undergone successive upgrades by the Black family, it is ultimately just a Rank 6 house. Compared to the temporary train built in the underground base, it's not much better; they're only roughly equal. After all, the underground base incorporated some new technologies during its construction, resulting in an overall performance improvement over a typical Rank 6 Immortal Gu House.

So if the eldest son really wanted to, a blatant, overwhelming barrage like this could cripple Black City. But clearly, what he wanted wasn't to cripple his opponent, but to completely seize the treasure in his opponent's hands. He had already obtained half last time, and this time he was determined to get the other half, and also to take Black City himself.

Black City sensed the eldest son's weakness; the intercepting firepower was far weaker than when he had encountered it before. However, considering the size difference between the two stages, this was to be expected. He showed no mercy, instead swiftly smashing it directly above the eldest son. Like a meteorite, it crashed down upon the eldest son's head.

He had initially expected a clash of titans, a collision of planets. Even though he was much smaller than his eldest son, the energy he contained was immense, and he had already unleashed his signature killing move. Logically, even in a head-on confrontation, he shouldn't have suffered a loss. However, the power of his attack was completely absorbed by his eldest son. Having become accustomed to fighting in low temperatures, even his outer insulating shell possessed a degree of self-regulation. After absorbing the massive energy, it could even guide it, ensuring that it not only wouldn't cause damage but would also be absorbed to some extent.

The underground base's attack was able to harm the eldest son because they had learned this lesson the hard way. Therefore, when attacking, they deliberately insert virus-like codes into the energy. If actively absorbed, this would cause energy imbalances within the eldest son's body, and many of their weapons also have self-destruct systems. The absorbed energy would instantly explode, destroying the eldest son's insulating layer.

These kinds of intelligence are difficult to discern with the naked eye, so Black City didn't realize it. He simply led a ragtag group forward, hoping to strike while the enemy was weakened. Little did he know it was all a meticulously planned trap. He was like someone plunging into a swamp. No matter how desperately he released his energy, it was like throwing a stone into the sea. He saw absolutely no feedback. The massive black prison slowly sank into the swamp of flesh and blood on the eldest son's body.

He had certainly considered escaping. Although this item belonged to the family and was extremely valuable, it couldn't be discarded casually. The Hei family understood the principle of sacrificing land for people, or people for land. While the Immortal Gu House was priceless, it was still inferior to a seventh-level immortal. Therefore, within these seemingly agonizing environments, there were escape routes. Theoretically, escaping was possible if one could trigger one of these routes.

But things clearly wouldn't go so smoothly. When Hei Cheng tried to escape, countless tentacles reached out and enveloped the entire Black Prison. The Black Tower was a type of Immortal Gu House designed to trap and slowly erode enemies. It possessed spatial attributes, but was internally sealed off, with virtually no external spatial jump capability. Firmly sealed by the tentacles, only spatial jumps could allow escape. After discovering the safe passage was also blocked, Hei Cheng had no choice but to temporarily summon his Gu worms to attack and break through the tentacles sealing the exit. Fortunately, his attacks were small and precise, with extremely high cohesion and accuracy, making them highly susceptible to external interference. He fired three black arrows, originally intended to strike the person directly in the forehead, thus instantly killing them. These arrows were not only accurate but also virtually impossible to defend against or dodge, with maximum tracking effect. It was arguably one of his most effective killing moves.

This thing was clearly not the type to cause large-scale destruction. At most, it could create a survival path for him. The area of ​​destruction was small; he only managed to smash out a tunnel barely wide enough for one person to pass through. Fortunately, his attack was extremely concentrated, impossible to be absorbed, and had a fixed trajectory, making it impossible to interfere with or guide. It simply carved out a tunnel, albeit one that couldn't be guided or interfered with. This didn't mean the eldest son was helpless. So what if he created a hole? He could just patch it up. Flesh and blood were plentiful for him. Besides, he had already laid an ambush here—a true master he had created himself.

Chen Feng never imagined that he would obtain the Immortal Gu for the first time under such conditions. In a sense, his reckless charge before had indeed fulfilled his wish. He not only obtained the enhancement of his eldest son's flesh and blood, but also obtained the eldest son's Immortal Gu. The only thing he lost in the process was his free will.

The price paid was enormous, but the strength of the Gu worm he obtained was also outrageously high; even among sixth-rank immortal Gu, it was relatively powerful. A sixth-rank immortal Gu, a swapping immortal Gu—that's what he now possessed. It's somewhat similar to the attribute swapping ability of the Eighth Burning Legion, allowing him to transfer the attributes of others to himself. It can even swap his strongest past state with his current state, thus achieving the blessing of eternal glory. If used well, it's incredibly powerful. Furthermore, this Gu worm's swapping capabilities extend even further, such as spatial swapping, exchanging the positions of two people, or swapping the positions of a person and an object; at close range, it can even be used as instantaneous teleportation.

However, if one were to suddenly exchange the life force of both combatants during battle, performing the exchange when near death, gaining the opponent's abundant life force while transferring one's own near-death state directly to the opponent, it would almost certainly be a decisive victory. However, all of this obviously comes at a cost; gaining immense power requires paying a price. Fortunately, his current costs can be covered remotely by his eldest son. This allows him, despite only being a sixth-level cultivator, to dare face the seventh-level Black City cultivator.

Chen Feng blocked Hei Chang's escape route at just the right moment, and then saw him instantly switch positions with Hei Cheng, pulling him from the place where he was about to escape into the middle of Changzi's trap.

Black City never imagined that he would encounter humans while fighting monsters. He was timid and submissive when facing monsters, but he unleashed his full power against humans.

"How dare you! Do you know who I am? Do you know what's behind me? I am Hei Cheng of the Hei family. Aren't you afraid of the Hei family's retaliation for trying to ambush me at this time?"

As he spoke, a jet-black sword was launched—the very attack that almost always struck the forehead. Although its power wasn't immense, its ability to directly destroy the brain was still quite devastating. Even for a celestial being, such a direct attack would cause severe brain damage.

Chen Feng naturally wouldn't sit idly by and wait to die. He instantly switched positions with the black arrow, but the black arrow turned around instantly and shot towards his forehead without slowing down at all. This meant that ordinary methods were simply not enough to dodge it.

This move isn't invincible. The best way to counter it is to continuously retreat while unleashing powerful attacks. This will gradually weaken the move's power, and if continued for a long time, it can be reduced to nothing.

However, he clearly lacked such ability, so he decisively stood still and took the hit head-on, choosing to stand on the eldest son's tentacle to withstand the attack. After connecting with the eldest son, his life force and body tissues achieved a certain degree of sharing. At the moment of impact, although his head was still relatively intact, his brain had been shredded into a mass of minced meat. For an ordinary immortal, this would have been a serious injury, but for him, who possessed a large number of the eldest son's cells, the brain was merely one of his thought processes. Cells from any part of his body could serve as his thinking organs, especially after his body was connected to the eldest son. The neural network transferred his thoughts to the eldest son's body, so although his brain was destroyed, it did not cause too much damage to his current physiological functions. In an instant, his brain was completely repaired. And his self-awareness returned from the eldest son's body to his own brain. The entire process lasted only a few seconds.

"Trying to use the Black Family's identity to intimidate me now is a bit too late. Don't you think it's strange? Why didn't the eldest son attack me? Why wasn't I attacked by the tentacles even though I was standing on the eldest son's flesh and blood? Sometimes the answer is right there in the open. If you can't even understand this, and why I have no respect for the so-called Black Family, then there's probably no need for your brain to be devoured by the eldest son."

Hearing this, Hei Cheng felt a chill run down his spine. How could anyone possibly side with the eldest son? How could anyone stand firmly in the eldest son's camp? This question was not suitable for in-depth consideration, because in-depth consideration would become extremely terrifying.

The eldest son has a way to silently change a person's will in a short period of time, and to make that person genuinely obey him. This is terrifying, much like the difference between ordinary genjutsu and Kotoamatsukami in Naruto. When under ordinary control or a contract-like control, one will actively try to break free, but if one genuinely obeys, even the thought of breaking free will not arise.
