It was called "The Yin-Yang Limitless Dao Codex."
Although the name was somewhat ordinary, it encompassed everything.
As the saying goes, understand one method, and you understand all methods.
Since the Dao of Yin and Yang is the supreme principle of the universe, learning this technique would allow him to understand and use other people's divine abilities and techniques with just one look or one try.
It was similar to the "Xiaowuxiang Skill" from his previous life's martial arts novels.
However, this was even more advanced, capable of simulating various divine abilities and wonderful techniques.
It could even emulate the Heavenly Dao, directly simulating the power of laws, even if those laws had not yet been comprehended.
Of course, this required cultivating to an extremely high level.
More importantly, this technique truly led directly to the Limitless Grand Dao.
Cultivating to the highest level would allow one to achieve the Primordial Limitless Golden Immortal state, becoming an existence equal to the Heavenly Dao.
Lu Xin naturally wanted to learn it, but he first needed to integrate this technique into his "Chaos Sword Art."
No, because this technique was too high-level, it could only be used as the main framework, with the existing "Chaos Sword Art" integrated into it.
This required changing the previous idea of combining ten thousand Daos into Chaos.
It might seem a bit impulsive.
But there was no other way.
The existing "Chaos Sword Art" used the "Five Elements Positive Lightning Method" as its main framework. Although it contained a Mixed Origin Golden Immortal level curse-type technique, the difference between the two was too great.
After reaching the Grand Luo Golden Immortal realm, cultivation would not be as smooth, and it would lean towards the curse side, while the lightning method would not continue to improve.
In the end, the "Five Elements Positive Lightning Method" was just a Taiyi Golden Immortal level technique.
After reaching the Grand Luo realm, even with the support of laws, the effect of this lightning would become less significant.
It would only be slightly stronger than ordinary Grand Luo level divine abilities.
But now it was different. The "Yin-Yang Limitless Dao Codex" inherently contained the Five Elements and Lightning.
He only needed to make slight changes to evolve the Five Elements Positive Lightning into Yin-Yang Divine Lightning.
This lightning seed belonged to his own creation, and could be extracted separately. He didn't know if it existed in the present world.
In short, he could now connect all his knowledge into a single line, creating a complete system.
In the future, when training disciples in lightning techniques, he wouldn't have to worry about having no follow-up after teaching them to the Golden Immortal or Taiyi level.
Thinking of this, he wasn't in a hurry to leave seclusion, and began to deduce the technique.
Several months passed, and he had already deduced the Yin-Yang Divine Lightning. This was both a technique and a divine ability, and he had already learned it.
He spent another period of time experimenting and perfecting it.
After cultivating to the Taiyi level, he walked out of the [Scroll of Years] and came to the depths of the Black Water to test the final effect.
As soon as the Yin-Yang Divine Lightning appeared, various phenomena immediately manifested.
There were flowers, plants, trees, mountains, rivers, oceans, and the stars of the Nine Heavens.
This was a world in itself, where all things were both themselves and lightning.
Finally, the world shrank, transforming into a crystal ball, merging into his palm, flickering uncertainly.
"Destroying a Celestial Domain planet with this divine lightning should be no problem, right?"
Looking at the world in his palm, Lu Xin's eyes were bright.
This crystal was the embodiment of the Yin-Yang Divine Lightning, the ultimate compression of this lightning Dao, containing the principles of Yin and Yang.
It was not only incredibly heavy, but also extremely powerful.
Not wanting to cause too much commotion, Lu Xin didn't throw it out, but directly let it dissipate, and then returned to his secluded cultivation place.
As usual, he scanned the surroundings, and found many unfamiliar figures nearby, wondering if something had happened.
After a careful scan, he realized that they were attracted by the phenomena he had emitted when testing the lightning earlier.
Even though he had tried his best to suppress it, and hadn't even triggered the power of laws, he didn't expect it to spread so far.
However, he didn't care too much, seeing that they were all heading towards the Black Water, and ignored them.
He planned to check the cultivation progress of Hua Nu and the others.
With the existence of Star Spirit Fruit flesh, plus the [Scroll of Years], the progress of the others had naturally been rapid during this time.
Hua Nu had already become a late-stage Celestial Immortal, and was now advancing towards the True Immortal realm.
Zi Wan had also reached the late-stage Human Immortal realm.
Little Vermilion Bird and Chen Ruoyan had both passed the Bi Wind Tribulation and become early-stage Celestial Immortals.
It's worth mentioning that Hua Nu had been experiencing more and more unfamiliar images flashing through her mind recently, even affecting her concentration on cultivation.
However, she could never remember them.
She told Lu Xin, but he still couldn't figure out what was going on.
Seeing that it wasn't having too much of an impact, he could only have her temporarily stop cultivating. After a while, he would go out and inquire about the specific reason.
Now that his Yin-Yang Divine Lightning was complete, and his understanding of laws had reached an extremely high level, he dared to face even Grand Luo Golden Immortals head-on.
So he decided to go now.
"Master, I'm sorry, it's all Hua Nu's fault." Hua Nu lowered her head, obviously feeling bad for troubling Lu Xin so much.
"What nonsense are you talking about?"
Lu Xin patted her head, "What kind of relationship do we have? You helped me before, and now I'm helping you. Besides, inquiring about some things doesn't take much effort."
"But it will delay your cultivation." Hua Nu pouted, knowing that Lu Xin was constantly being hunted down, and also knew about the five-thousand-year agreement.
She had been working hard to cultivate.
But now it would take up his time.
However, how could she know that, apart from the five-thousand-year agreement, Lu Xin didn't care about being hunted down at all.
"Okay, don't overthink it. Cultivation is about balance. I just happen to want to go out for a walk, maybe I can find some treasures."
"Also, I'm still counting on you to help me when your cultivation is high."
"So I need to solve your problem as soon as possible."
After comforting her, Lu Xin told Zi Wan and the other two, and then put away the [Scroll of Years] and the Crying Luan Immortal Palace.
Then he left this place.
The first stop was naturally Fengshan Prefecture.
As the master of a prefecture, and an old Golden Immortal expert with considerable strength, he would definitely have more knowledge than him.
And he was also the closest, so he might know something.
At the very least, he could provide some clues, so he wouldn't have to wander around aimlessly.
The Prefecture Lord of Fengshan could be considered an old acquaintance. Lu Xin's silent appearance was obviously beyond the other party's expectations.
"Han Qianqiu greets Senior!"
This time, the prefecture lord was even more respectful.
Lu Xin was somewhat surprised, and after inquiring, he understood the reason from the other party's cautious explanation.
It turned out that it was because of Lu Xin's performance when facing several Grand Luo experts inside the Black Water Underworld Palace that day.
It could be said that he was handling it with ease.
So while feeling incredulous, he knew that although his strength was in the same realm, it was incomparable.
Lu Xin could have imagined this, but the only thing he didn't expect was that the Netherworld's Extermination Palace had actually sent people to inquire about his situation in detail afterwards.
Therefore, the Prefecture Lord of Fengshan learned his true identity and origin from them.
He was actually being chased by the Xuanwu Great Emperor of the Immortal Realm.
This also meant that he could escape from the hands of a Mixed Origin Golden Immortal.
He was definitely extraordinary.
So that's why he was so respectful when they met again.
Lu Xin never expected that being chased by someone would have this kind of effect.
Too lazy to think too much, he focused his attention on the Netherworld's Extermination Palace.
He knew about the Extermination Palace, the residence of one of the Netherworld Emperors, the Extermination Emperor, but he didn't know why they would send people here to investigate him.
"Could it be because of the matter with the Prefecture Lord of Black Mountain?"
He had a guess in his mind, and since he had been exposed, he simply said:
"Take out your Netherworld's wanted order for me, or the wanted notice."
"What wanted order?" Han Qianqiu looked blank.
"Hmm? Could it be that they haven't connected me with the murder of the Black Mountain Lord? Or is the person in front of me pretending to be ignorant?"
Lu Xin frowned slightly, and asked again: "Has your Netherworld issued any wanted orders regarding people from the Immortal Realm?"
"People from the Immortal Realm, isn't that..."
Han Qianqiu reacted and quickly said:
"Reporting to Senior, the Netherworld knows that you were the one who killed the Prefecture Lord of Black Mountain, but the Extermination Emperor has issued an order not to make things difficult for you."
"Not to make things difficult for me? That's strange."
Lu Xin was even more surprised now. He had nothing to do with this Extermination Emperor, and didn't understand why the other party would issue this order?
"Do you know the reason?"
Han Qianqiu was still looking at him inquisitively, obviously wanting to know the relationship between him and the Extermination Emperor.
"I can answer that question myself."
At this time, a clear and cold voice suddenly entered.
