Put simply, in this world's Martial Dao, the more acupoints one's Vital Energy traveled through, the higher the grade of one's cultivation method and Martial Skills.
Of all the cultivation methods and Martial Skills Zhang Ming had mastered, only the [Mighty Bull Cultivation Method] reached 300 acupoints.
Of those 300 acupoints, more than two hundred came from the fusion of three Mighty Bull Cultivation Methods. The remaining several dozen came from more than ten manuals gathered from Yang City's various Martial Arts Halls and Gangs.
More than ten cultivation methods had only added several dozen acupoints. One could imagine just how difficult it would be to improve beyond 300 acupoints.
Likewise, the Black Tiger Saber's 66, the Great Wind Leg's 55, the Five Poisons Art's 45 in medicine and poison, and the Consecutive Shot hidden weapons' 33 in bows—all of them had been formed by fusing varying numbers of Martial Skills.
It was simply that, in this tiny patch of Yang City, the quality of Martial Skills truly was not high.
Even after fusing multiple Martial Skills, the Black Tiger Saber had only reached 66 at most!
Still, Martial Skills were Martial Skills, not cultivation methods.
Their execution through Vital Energy did not require it to travel through the entire body.
In other words, the Black Tiger Saber with its 66 acupoints had already reached the Postnatal Realm of Martial Skills.
It was already a top-tier powerful Martial Skill in Yang City!
In short!
"I'm so strong."
"An Innate Realm supreme cultivation method plus Postnatal Realm Martial Skills—who in Yang City could possibly be my match?"
Zhang Ming suddenly fell silent, then gave an awkward smile.
"No one had been my match more than a month ago. Now, there's even less of a chance."
"Hehe."
After chuckling a few times, Zhang Ming ignited the "system" and burned it into ashes.
Thus, a generation of "systems" perished.
"When it comes to raising the quality of cultivation methods and Martial Skills, without other cultivation methods and Martial Skills to serve as fuel, relying on myself alone will be extraordinarily difficult."
"In other words, my progress in strength will enter a stable period for a while."
"Ordinary cultivation methods and Martial Skills are basically useless to me now. At the very least, they must be Postnatal Realm cultivation methods or Martial Skills. But who wouldn't treasure something of that level?"
Zhang Ming frowned, a thought forming in his heart.
"Perhaps... they can help me?"
The Mysterious Buyer's figure suddenly surfaced in his mind.
"I wonder how many cultivation methods they've collected for me. I informed them more than a month ago."
Zhang Ming's cooperation with the Mysterious Buyer was mutually beneficial.
But compared to the armor and weapons, bows and crossbows, and other items the buyer needed, Zhang Ming did not have such a great need for money.
Therefore, during the early stages of their cooperation, providing some reasonable assistance with requests had also been included in the details of the agreement they reached.
Now, helping him search for cultivation methods and Martial Skills was precisely one of Zhang Ming's requests.
Suddenly, while pondering these matters, Zhang Ming sensed something.
He looked toward the door.
"You're here."
"I'm here."
"You shouldn't have come."
"Hm? Why?"
"No, no, no. Just a joke, Yingxue. Don't mind it."
"Hmph. Can I come in?"
"Yes, yes, come in."
Ever since Zhang Ming had threatened Jiang Yingxue last time that he would terminate their cooperation if she entered without knocking again—
In their subsequent meetings, Jiang Yingxue had always knocked very politely.
From this, it could be seen that Jiang Yingxue, this Martial Dao Grandmaster, was actually quite a nice person, and very easy to talk to.
She had the air of a white lotus untouched by society's filth.
At the same time, this also indirectly showed just how enormous the force capable of raising a Martial Dao Grandmaster into a white lotus must be.
At the very least, it had a Great Grandmaster at its foundation, perhaps even a Martial Saint above.
The door was opened by a pair of fair, slender jade-like hands, and Jiang Yingxue, dressed in black with her face covered, appeared before Zhang Ming.
Without any intention of exchanging pleasantries, Zhang Ming went straight to the point.
"Where are the things I asked for?"
"They're all here."
Jiang Yingxue tossed over a bundle and said coldly.
"Is there anything else? If not, I'm leaving."
"Hey, hey, don't be in such a hurry."
While placating Jiang Yingxue, Zhang Ming opened the bundle and quickly checked the items inside.
The bundle was not large, merely the size of an ordinary backpack.
But what it contained was anything but ordinary: more than ten cultivation manuals of all kinds, collected by the Mysterious Buyer at his request.
After a brief inspection, he found that only a few of the dozen-odd manuals were duplicates. The rest were "new goods" he had never seen before.
Zhang Ming nodded, fairly satisfied inwardly.
But in business, one could not show any positive emotion in front of one's own son.
He, the seller of armor and weapons, was the client's daddy.
Zhang Ming frowned.
"Out of these dozen-odd cultivation methods, I already have several. Of the rest, only three are Postnatal Realm. There isn't even one Innate Realm cultivation method?"
He looked at Jiang Yingxue, his eyes filled with a trace of dissatisfaction.
"I don't feel even a shred of sincerity!"
"I think I need to reassess our cooperation."
Jiang Yingxue was furious, a flush of anger creeping across her cheeks.
But recalling what her master had said before she left, she forcibly suppressed the anger in her heart.
She said nothing, merely taking another booklet from her robes.
She said coldly.
"Here. This should be enough!"
After saying that, Jiang Yingxue once again turned to leave.
"Hey, hey, hey, why are you in such a rush? What's wrong with letting me inspect the goods?"
"You're a Martial Dao Grandmaster. Why are you so impatient?"
Don't get angry, don't get angry, don't get angry. He's someone Master specifically mentioned, specifically mentioned. Don't get angry, don't get angry.
Muttering this in her heart, Jiang Yingxue stopped and waited for Zhang Ming to inspect it.
"Formless Witness Technique?"
After casually flipping through a few pages, Zhang Ming discovered that this cultivation method was extremely peculiar.
First of all, its grade was unusual. This [Formless Witness Technique] was actually an ungraded cultivation method, or rather, one whose grade could not be determined.
Second, it was exceedingly difficult to cultivate. The entire text was shrouded in mist and clouds, leaving one completely unable to make heads or tails of it.
Finally, this cultivation method perfectly suited Zhang Ming's requirements.
More than a month ago, when communicating with Jiang Yingxue, aside from requesting a large number of cultivation methods and Martial Skills—
He had also asked her to seek cultivation methods or Martial Skills for training eyesight or spiritual power.
There was no need to explain the purpose of cultivating those two things: it was to search for and unravel Spiritual Energy.
It was an attempt to pave the way for the cultivation path he had just "created a new folder" for.
And this [Formless Witness Technique] could be said to perfectly fulfill both of Zhang Ming's requirements.
As its name suggested, the [Formless Witness Technique] recorded that once Great Accomplishment was reached, one's eyes would become like those of a god.
Anyone witnessed by those eyes would tremble with fear, their hearts splitting with terror as boundless dread arose within them.
It also possessed the effect of strengthening one's eyesight.
It could train eyesight while also increasing spiritual power. Did that not fulfill all of Zhang Ming's requirements?
"Not bad. I suppose I'm barely satisfied this time."
Zhang Ming looked it over, putting on an uninterested expression before turning his gaze toward Jiang Yingxue.
"For the next transaction, I hope you bring Heavenly Materials and Earthly Treasures."
"Zhang Ming!"
"Are you insane? You dare ask for Heavenly Materials and Earthly Treasures? Even for us, things of that level are rare treasures!"
Jiang Yingxue was enraged, furious at Zhang Ming's greed.
"Look at you, getting worked up again."
"I know you're in a hurry, but don't rush. Listen to me first."
"Hmph—" Jiang Yingxue snorted coldly, waiting to see how Zhang Ming would talk his way out of this.
"I intend to add an item to our transactions."
"What item could be worth Heavenly Materials and Earthly Treasures?"
"Phosphate fertilizer!"
"What? What is that?"
Zhang Ming smiled faintly.
"Something that can multiply crop yields!"
Phosphate fertilizer was a type of chemical fertilizer, one of the foundations of agricultural technology in his previous life.
The birth of phosphate fertilizer had been entirely accidental.
Some time ago, workers at the Mine had discovered a strange ore at its bottom.
After appraising it, Zhang Ming had been shocked to discover that it was high-quality phosphate ore.
And with the help of [Ignite Comprehension], he had successfully "excavated" the production method for phosphate fertilizer.
"Multiply?"
Jiang Yingxue's mouth fell open, disbelief written across her face.
"Are you sure it multiplies them? You're not joking?"
"Would there be any point in lying to you?"
"I need to report this when I return. I can't make this decision."
Of course Jiang Yingxue understood how terrifying it would be to multiply food production.
Precisely because she understood, she knew even more clearly that this was not something she could decide.
"Fine, I understand. Take care, then. I won't see you out."
