Ming Aolian and the others were in the disbelieving that Lin Mu had shown them the jade slip at first.
They had thought that it was a Legacy Treasure which should only be passed down from a master to a disciple. It was the culmination of all knowledge and information they would have gathered in their life, as well as the past generations.
That was how substantial the information compiled in the jade slip was.
Ming Aolian had merely thought of it as a very detailed Beast record, but when seeing that there were other parts to it, she was stunned into thinking about a Legacy Treasure. After all, there was no reason why someone would spend this much effort to make a jade slip like this.
It was not a simple task, and would take time away from cultivating. It was time that was precious and would leave them lagging behind their peers if they wasted it.
Of course, this only applied to those who couldn't do multiple things at once. For Lin Mu who could be in the Sleepscape while continuing to cultivate, it was merely a means of optimization.
Plus with his practice with the formations and runes, gathering information and compiling it was a basic task that he had been doing regularly. The only reason why he had such an expansive records were due to the fact he had the memoirs of the Lost Immortal as well as Xukong to guide him.
This allowed him to expand upon the preexisting records that he had and further improve them. There were often details missing about various articles that he could add too on his own.
He would also add his own observations and understanding of things that he saw.
With all this combined, the jade slip that Lin Mu ended up making was something that was good enough to be mistaken as a Legacy Treasure.
"It really isn't a Legacy Treasure?" Ming Dandan asked in doubt.
"It isn't, I made it." Lin Mu replied. "I might have taken some guidance, but I made it completely by myself." He clarified.
"This…" it still felt rather stunning to Ming Aolian and the others.
To be able to reach his current cultivation base while also doing something like this was a tall order. Not many would be able to do this and would probably lags hind in some aspects of their cultivation.
And yet, here was Lin Mu who could stand above them despite being of a lower cultivation base on the outside. They didn't know what to do other than to just believe Lin Mu.
'Though it does make sense with how casually he showed it to us…' Lu Xu thought over it. 'If it were a Legacy Treasure I doubt many would even dare to take it out in the presence of others.' He reckoned.
The others came to term with it as well and finally calmed down.
"Still… this is very impresser." Qian Wen spoke. "I don't think I've seen anything like this even in the Royal Library."
"You've been to the Royal Library? Don't they only allow the aristocrats there?" Luo Liqin asked.
"Ah, I was assigned as a guard there." Qian Wen clarified. "Though they did allow us to look through the document and books as long as they were returned properly." He added.
"That makes sense then." Luo Liqin nodded his head.
"I can say the same. I don't think there will be anything this comprehensive in the Blue Mountain Palace either." Ming Aolian stated. "They might have separate documents and books that might have similar amount of information, but it won't be compiled into one jade slip like this." She explained.
"Mmhmm, that is true. Not many powers would take the risk of doing that. It is the same as asking thieves and other foes to simply sabotage it. One could lose risking the foundation of their legacy like this." Lu Xu nodded his head.
It was a common practice to keep all the intimation and techniques a power had, separate. This made it so that if something happened to damage or steal them, they wouldn't all be gone at once.
Of course, there were some compilations made, but they were in the form of Legacy treasures like Ming Aolian had said. They would only be passed down among a few people in such powers and usually belonged to the heirs and masters.
Thus it was very rare for such a expansive compilation to be found.
One might ask, why wouldn't they simply make multiple copies if they feared it getting stolen?
The answer was mostly about time and effort.
A jade slip that could accommodate this amount of information was of a high quality and needed a formation grandmaster to make them. Then there was the fact that one still needed to transfer the information over from an original source.
This in itself was a item consuming task. One could very well assign some disciples to do this, but that would also mean that there was a chance of things getting leaked. After all, something like this was valuable and needed to be kept secure.
This meant that only a few people could carry out a task like this, and such people often had other important tasks to do or spent their time in cultivation.
All of this ended up meaning that it was very rare for a jade slip like this to be compiled with all the information of a power.
"Just show's how great Brother Mu Lin's skill set it." Luo Liqin couldn't help but praise.
"Indeed." Ming Aolian and others chimed in agreement.
Lin Mu could only give a smile in gratitude before resuming the lesson.
"Let's get back to it then, shall we?" Lin Mu said, refocusing their attention.
A few hours passed like this before Lin Mu and Ming Dandan picked out on a potential beast that she could tame. Best part was that it could be found on Rust Sky world itself, and one wouldn't have to look outside.
