Gu Nan was actually very knowledgeable on how to take control of a world.
To explain it in the game's words, it essentially involved turning a normal dungeon into the player's personal dungeon. Gu Nan was already exceedingly familiar with this process.
Discover the dungeon's core law, then kill the boss inside the dungeon who has the ability to control this law—this boss will often be the dungeon's ruler.
Of course, Immortal Demon World was different.
Zuo Zuo had clearly already abandoned this place and re-established his astral world elsewhere. After the statue was shattered, only Yan Xiaoxiao and Xue Yan, the twins, could compete with him for the right to control this world.
As soon as Gu Nan's voice fell, his body exploded with power, and a fist mixed with the power of law nullification punched towards Yan Xiaoxiao, the nearest enemy, without hesitation.
"It's useless." As Yan Xiaoxiao's voice rang out, a dim light flashed from the shattered remains of the statue, inexplicably isolating Gu Nan.
Gu Nan was very familiar with this kind of power. It was the repulsive force from Immortal Demon World, except this time it isolated him from everyone else.
"If you want to control 'fusion,' you must first fuse completely with something. We are originally one to begin with, but who are you willing to fuse with?"
Xue Yan and Yan Xiaoxiao said simultaneously, holding hands as if they were one person.
A person slowly appeared in front of Gu Nan. It was an unfamiliar Prodigious cultivator who didn't even know why he appeared here and was looking around in astonishment.
Information inexplicably entered Gu Nan's mind. Only when he decides to fuse together with the person in front of him will he obtain the right to fight for control over the law of fusion.
Gu Nan's expression looked a little ugly. He knew that, in fact, Zuo Zuo screwed him over this time.
In order to make his own arrangement a reality, Zuo Zuo deliberately set up such a strange condition, which was completely tailor-made for Yan Xiaoxiao and Xue Yan!
Besides the two of them, who else would be willing to fuse their own soul with someone else's?
It was no different from when certain employers in Gu Nan's past life recruited civil servants—they directly stated that the candidate must have a certain surname, be a graduate of a certain university with a certain major, and the candidate's height must be 1.75 meters and can't even be one centimeter short.
"Don't you guys feel like you're obeying an imperial edict when you do this?"
Gu Nan rolled his eyes and said something that the two couldn't understand, then punched the person in front of him into smithereens without hesitation.
But the law of fusion was even faster. Without any delay, another Prodigious cultivator's soul was caught and appeared in front of Gu Nan.
The person this time could be considered an acquaintance. It was precisely Gu Nian's junior brother in the Gu family, Gu Qing.
He had even met Gu Nan before when he was in the Gu family. At this time, he immediately blurted out, "Young Master Nan…"
Bang!
Gu Nan didn't have any scruples about killing acquaintances. Gu Qing's head was also blasted to pieces. His soul instantly scattered into nothingness, and the next fusion target reappeared.
The third one, the fourth one… Just like this, Gu Nan killed them one after another.
"Your actions are meaningless."
It was now Xue Yan and Yan Xiaoxiao's turn to frown. They didn't understand Gu Nan's actions. 'Don't tell me he still wants to wait for a suitable fusion target to appear?'
But in reality, nobody was a particularly suitable fusion target for Gu Nan. It would be the same no matter who he chose.
However, on the other side, a voice slowly spoke from among the spectators, "He might be planning to… kill everyone."
Lu Zhanyu's face was pale as she stared at Gu Nan. She was the one who spoke just now. She, who once worked with Gu Nan on missions, knew Gu Nan's thought process better than anyone else.
'As long as everyone is killed, there will be no fusion target for him anymore… He really is capable of doing such a thing!'
While she was talking, Gu Nan's killing was becoming more and more efficient—he still needed one punch to off Prodigious cultivators, but he only needed to move a thought to use his law to pulverize those below Prodigious realm.
"Slaughter the whole world?" Even Wu Gui raised her eyebrows slightly. Not even she had ever considered such a crazy notion before.
Gu Nan was still wordlessly killing everyone who appeared before him. He was indeed planning on doing exactly that.
There were obvious flaws in the law of fusion's requirements. As long as less than two fusion targets remained in this world, then the law would naturally be unable to capture a second fusion target for Gu Nan, and it would naturally fail to meet its own requirement.
Under such circumstances, the law would automatically enter a sealed state, which players would then be able to manipulate at will—this wasn't the first time players found loopholes in the system.
And in reality, Gu Nan actually needed to kill a lot less people than imagined.
Those who didn't cultivate to a certain realm couldn't be captured because their souls weren't strong enough, and they would be directly annihilated in the collection process.
In other words, Xue Yan and Yan Xiaoxiao were running out of time.
As if they realized this, the speed of the two women's fusion suddenly accelerated, but the next person to do something wasn't Wu Gui, but Stephen lying on the ground.
This corpse flower pretended to be dead for quite a while, but then he suddenly jumped up. While Gu Nan didn't have time to pay attention to him, he tore open the void and shot into the portal.
Wu Gui shook her head slightly. She also broke through the void with a wave of her hand and offhandedly took Ye Chen with her while leaving.
The inheritance was destroyed, and it was meaningless for her to merely get this world, so she very smartly chose to leave—while Gu Nan was still uninterested in killing her.
Only Gu Nian and Lu Zhanyu remained in the scene, looking at each other with bitter smiles.
They didn't have the power to tear open space, so naturally they couldn't escape. They could only wait for Gu Nan to "pull" them and become a departed spirit under his fist.
The two women both knew Gu Nan very well. Neither believed that he was someone who would care about old acquaintances.
As for reincarnation, it didn't matter anymore—even this world was collapsing. How could they possibly take back the half of their souls stored inside the world's origin?
Even the method of terminating reincarnation failed, so death seemed to be the only path that awaited the two.
"There's another way," Gu Nian said in a heavy voice.
Lu Zhanyu stared blankly for a few seconds, then turned to look at Gu Nian, who was looking at Xue Yan and Yan Xiaoxiao, as well as the radiance given off by the statue's pieces.
She understood the other party's meaning. In the end, Gu Nian was still the more decisive one in this do or die situation.
"We have no other choice. There's no other way out. Indeed, we can only fight for this miniscule chance," Lu Zhanyu smiled self-mockingly and looked at Gu Nian again.
Gu Nian's eyes contained only decisiveness. She stretched out her right hand and placed it in front of Lu Zhanyu, who took it without hesitation.
Just like Xue Yan and Yan Xiaoxiao, the two of them slowly walked to the front of the statue fragments, and an inexplicable force began to descend upon them.
Xue Yan and Yan Xiaoxiao opened their eyes in astonishment, only to see an indescribable and mysterious connection appear between Gu Nian and Lu Zhanyu, which was still rapidly strengthening.
A pair of unexpected competitors.
If they wanted to have a chance of survival under Gu Nan's hands, they had to personally enter this fusion competition!
As long as they started the fusion process, they could at least ensure their souls' safety; the law of fusion wouldn't directly "sacrifice" them to Gu Nan.
Now it was a race to see whether Gu Nan would finish killing off all living creatures in this world first or whether they would finish taking control of this world's origin first.
But at this time, a scene that no one expected happened.
When Gu Nan destroyed yet another fusion target, the law of fusion seemed to freeze slightly in between captures, then slowly materialized a figure.
And the soul that appeared this time was a giant corpse flower—this was Stephen, who'd just fled into the void!
"Why…" Stephen's inverted human face exclaimed in disbelief. He couldn't understand why the law that could only act upon this world would also affect him, someone who had already torn through space and left.
But his confusion didn't affect Gu Nan's actions at all.
The heart symbolizing the power of law nullification was beating slowly. Gu Nan raised his fist and began to show a nasty grin on his face.
