Nangong Weiyang asked, "So you’re saying that Sword One’s Dantian has already changed?"

"That’s right," Gu Zhan nodded and said, "Through my recent perception, Sword One’s cultivation method is still similar to ours, still absorbing Heaven and Earth Primordial Qi for conversion. However, while the Dantian of normal people converts it into True Essence, Sword One converts it into a higher quality Demonic Qi."

Nangong Weiyang furrowed her brows and said, "If that’s the case, I suspect that your previous guess was indeed correct. Sword King City had ulterior motives from the moment they took Sword One as a disciple."

Gu Zhan said gravely, "You mean that Sword King City is researching a new form of cultivation, using Sword One as an experiment. The current results show that Sword One’s internal Demonic Qi indeed far surpasses True Essence in quality. If it can be disseminated in the future, it would mean that the people of Sword King City will far surpass martial artists of the same realm."

Nangong Weiyang pondered for a moment and said, "This explanation makes sense, but I still feel it’s not that simple, because the situation with Sword One is hard to replicate. Not everyone in this world has Sword Heart Clarity, nor can everyone cultivate the Yellow Court Scripture, and even fewer can become a Fallen Demon with just a thought."

Gu Zhan squinted his eyes and asked, "Can Sword One write the Yellow Court Scripture?"

Nangong Weiyang nodded her head and said, "It’s already been written. Sword One isn’t always in that state. Occasionally, he does have moments of real clarity. Over the past few days, in sporadic moments of clarity, he has narrated the Yellow Court Scripture, and I’ve transcribed it."

After speaking, Nangong Weiyang took a stack of rice paper from the desk beside her and handed it to Gu Zhan, saying, "Lord, unless you are absolutely certain, do not take risks."

Gu Zhan nodded and said, "Rest assured, I naturally have absolute certainty."

Nangong Weiyang nodded and asked, "Lord, have you thought through how to proceed?"

Gu Zhan said, "In the Inheritance Pavilion of the Beidou Bang, there is an Earth Tier Upper Grade Martial Arts called Celestial Fury Swordsmanship, which is a Demon Skill."

Nangong Weiyang nodded and said, "I’ve heard of this swordsmanship. Cultivating it to Great Success will lead to complete moral degeneration, becoming inhumane. The swordsmanship was created by a Supreme Grandmaster as a means of revenge and intended to oppose the Divine Techniques. It eventually ignited a bloody storm in the Martial World, only quelled when the Righteous and Demonic Daos united to besiege him."

Gu Zhan nodded and said, "This swordsmanship is nearly lost in the Martial World. The reason the Beidou Bang possesses it is that the Dragon King, in killing a Demon Dao Grandmaster, stumbled upon it. Initially, he planned to destroy it, but found it too valuable to discard, so he stored it away and never showed it to anyone, preventing its dissemination."

Nangong Weiyang expressed concern, "Lord, whether it’s this Celestial Fury Swordsmanship or the Yellow Court Scripture, they both have significant issues and the risks are too great. You should carefully reconsider.

I know, given your talent, you are certainly unwilling to remain in the Grandmaster Realm your whole life. Therefore, you plan to cultivate the Yellow Court Scripture certainly with this intention, but there’s no need to be too hasty. You’re still young, and there is time to find ways to explore the secret of the Grotto Heaven."

Gu Zhan smiled slightly and said, "You and I are thinking alike. When I suspected Sword King City had plans for Sword One, I anticipated it was related to the Grotto Heaven Realm. Otherwise, I can’t imagine another reason why Sword King City would be willing to sacrifice such a prodigy once in a hundred years."

Nangong Weiyang chuckled awkwardly and said, "I did indeed have that suspicion, but I feared that you might take risks because of it, so I never told you.

Because the Secret of the Grotto Heaven in the entire Xia Kingdom has always been controlled by the Three Sects, Four Families, and Eight Great Sects. Countless Martial World’s prodigies are isolated beneath this Grotto Heaven. Faced with such temptation, it’s difficult for anyone to resist losing one’s rationality, so I didn’t dare tell you, and I didn’t expect you to think this way too."

Gu Zhan smiled slightly and said, "Rest assured, I only proceed with absolute certainty. If I weren’t certain, I wouldn’t take such risks."

Nangong Weiyang gave it some thought and didn’t persuade further,

The more she interacted with Gu Zhan, the more clearly she recognized,

that Gu Zhan was an absolutely proud and confident person,

and once he made up his mind, no one could change him.

"Then I wish you success, my Lord!"

Gu Zhan nodded and said, "If you need anything, just have someone find me."

With that, Gu Zhan turned and left.

Nangong Weiyang watched Gu Zhan depart, tightly holding Sword One’s arm, and slightly leaning her head on Sword One, softly saying, "I truly hope his ability matches his pride and confidence, for those who conquer all are indisputable!"

...

Returning to the courtyard,

Gu Zhan began browsing the Yellow Court Scripture.

As he finished reading the Yellow Court Scripture, the system rang with a notification:

[Detectable Evolvable Technique Yellow Court Scripture, would you like to record it?]

Gu Zhan was taken aback,

carefully scrutinizing the system’s prompt, confirming that the notification highlighted ’Evolvable Technique,’ a first for him in a long while.

Previously, the system notifications only detected techniques,

but this time, it included an ’evolvable’ modifier before the technique.

He immediately willed it and chose to record it.

At the moment of recording,

as usual, technique analysis appeared,

the preliminary analysis was no different from before, detailing characteristics and quality of the technique, the corresponding realm for each tier, etc.,
