The preceding content was roughly the same as what Tian Zhen saw on the Seven-Star Coffin, the only difference being the latter part.
The latter part read: 【After Duke Lu's burial, Iron-Faced Birth found a death row inmate of similar build and set fire to his own house, faking his own death in the flames.】
【After arranging all this, Iron-Faced Birth left home and found Duke Lu's tomb, entering it. He dragged Duke Lu out of his golden-thread jade burial suit and placed him in a stone coffin.】
【Having done this, he lay down in the golden-thread jade burial suit himself.】
The silk document's content ended there.
There was no mention of subsequent events.
Zhang Yun Feng wasn't interested in that either.
Even if Iron-Faced Birth was powerful, he was just a wrapped-up corpse in a golden-thread jade burial suit; killing him would be child's play!
Right now, Zhang Yun Feng was most concerned with whether he could translate the ancient books for cultivation techniques, longevity, alchemy, or something similar.
Those things were important to him.
Then there was the system task, but unfortunately, it hadn't triggered in months.
Zhang Yun Feng speculated that the system task would only trigger when he encountered a specific person.
Setting down the Warring States silk document, he picked up a bamboo scroll and examined it.
A note was stuck to the bamboo scroll, containing a translation.
He picked up the note and found that its content was about opening the Ren and Du channels, and condensing true energy within the body.
While not a cultivation technique, Zhang Yun Feng was overjoyed.
Back when the Zhang family was at its peak, they had amassed a vast collection of martial arts manuals, but after countless wars and migrations, most of them were lost.
By his generation, only a few remained.
As a result, they didn't even know how to open the Ren and Du channels.
Based on the system's reward items, most of them were skills and techniques from martial arts novels, and these skills and techniques all relied on true energy to activate.
The more abundant the true energy, the greater the power it could unleash!
Therefore, opening the Ren and Du channels and condensing true energy in the body was crucial for him.
But he didn't rush to start practicing.
Who knew if the translation was accurate? If the method was wrong, it could ruin him!
To be safe, he decided to verify it with the translator.
The note below the translation indicated the translator's name, Jin Wan Tang. Coincidentally, it was Jin Wan Tang.
So, he took the bamboo scroll and went to the warehouse to find Jin Wan Tang.
"This translation is yours, right?"
Jin Wan Tang put down the ancient book in his hands, a little nervously, saying:
"It's mine. Is there a problem?"
"No problem, I just want to know, is the translation accurate?" Zhang Yun Feng said.
"Let me have a look..." Jin Wan Tang took the bamboo scroll.
Then he lowered his head and carefully examined it.
After a while, he said to Zhang Yun Feng with certainty: "The basic meaning is correct. This is a type of bird seal script from the Warring States period. I've been studying this ancient script for many years."
"That's good. Please make another copy of the translation. Thank you for your hard work!" Zhang Yun Feng patted his shoulder and left with the note.
Jin Wan Tang was stunned for a moment before scrambling to translate and rewrite a copy of the translation.
Back in his tent, Zhang Yun Feng carefully studied the contents of the note and started practicing methodically.
The first step in this true energy cultivation method is to sense true energy, to first find it within the body and then attempt to refine it.
But there's a prerequisite, that is, you must have a solid martial arts foundation. Only then will it be possible to condense true energy in the body, otherwise, you might as well not bother looking.
This condition was definitely met by Zhang Yun Feng.
As a Zhang family member, he had been subjected to various types of rigorous training since childhood, laying a solid foundation.
It was evident from his physical fitness.
Following the instructions on the note, he sat cross-legged on the ground, holding his breath and calming his mind, carefully sensing the true energy in his dantian.
But after sensing for a while, he didn't feel anything except his heart beating.
Zhang Yun Feng didn't get anxious, he kept practicing according to the method on the note, trying again and again.
After an unknown number of attempts, as evening approached, he finally sensed a wisp of true energy in his dantian!
The wisp of true energy, about the thickness of a finger, exuded a powerful force and pulsated gently.
But Zhang Yun Feng couldn't control it.
This was because he hadn't opened the Ren and Du channels yet. Only after these two meridians were opened could he circulate the true energy in his body.
Fortunately, the translation on the bamboo scroll included methods for opening the Ren and Du channels.
One was to consume a specific type of pill, relying on the pill's potency to open the Ren and Du channels, the quickest and most effortless way.
The other was through years of special training to open the Ren and Du channels. This method was extremely time-consuming and laborious.
It focused on innate talent. Those with good innate talent could open them sooner, while those with poor innate talent might not be able to open them in their entire lifetime!
As a man with a system, Zhang Yun Feng naturally chose the former, because the system store sold pills!
Thinking about this, he went back to the system store to check.
He found the pill section and browsed through it.
Soon, he found a pill suitable for him!
【Marrow-Washing Pill: Price 50,000 achievement points. Made with dozens of rare and precious herbs, consumption can refine the marrow, open the Ren and Du channels, and greatly enhance innate talent!】
The price of 50,000 shocked Zhang Yun Feng.
He only had 5,000 achievement points now, not even enough for half a pill!
"I need to quickly find monsters to farm some achievement points and get the Marrow-Washing Pill to open the Ren and Du channels as soon as possible!" Zhang Yun Feng made up his mind.
But within a hundred miles, there was nowhere suitable to farm achievement points, except that dangerous cave.
"What to do? Should I take the risk?"
Zhang Yun Feng was a little conflicted.
Of course, he wasn't the type to hesitate too much. After only a moment of contemplation, he made up his mind to take the risk.
Just then, Huo Xian Gu came to find him.
"Benefactor, it's time for dinner!"
"Got it." Zhang Yun Feng replied.
He got up and left the tent to have dinner with Huo Xian Gu.
He had decided to set out that night, so he took the opportunity to tell everyone while they were all together:
"I think there's something extremely important hidden in that cave. I need to go in and find out. I'll set out after dinner. If I don't come back, you don't have to look for me."
"Ah..." Huo Xian Gu looked at him with confusion, "Benefactor, you... can you not go? It's too dangerous there..."
The others also tried to persuade him not to go.
