While the Saintess checked out the Sword Nurturing Boxes, Lin Mu and the two immortal swords were busy gathering the Immortal Stones.

Lin Mu's immortal sense was also on the lookout for any other materials that might be mixed in with the Immortal stones. He didn't want them to get damaged during the extraction after all.

Plus Lin Mu now had an endless need for the Omnicore Ascendancy. While he had not started practicing it yet, once he did, his needs for resources would simply skyrocket. And when that time arrived, it was best he had the resources to use without any interruptions.

Though it was still unknown just how much Lin Mu would need in order to finish even a single elemental core. It was not like he had a reference for it either after all. He would have to figure it all out through trial and error in the future.

'Thankfully this mine is a lot wider and stable so there is no danger of it collapsing. The outer slate walls are also hard and won't break even if all the Immortal Stones are removed.' Lin Mu thought to himself.

This stability was the reason he was not going for the Source Vein directly. Though the fact that it was covered under hundreds of meters of Immortal stone also contributed to it. Thus if Lin Mu wanted to get it, he would still have to mine out the rest of the immortal stones.

He could now take his time mining it all out, and did so patiently.

Afternoon Pine and Ocean Raker did their jobs perfectly, while also getting to absorb the rich ambient Immortal Qi. Lin Mu simply followed after them while storing the chunks they were cutting up.

From time to time, he would also pause and extract some materials that were mixed along with the Immortal Stones. These were either different ores, or crystal that could be used for many purpose.

And as Lin Mu went further, he found better materials too.

By the time he reached the layer where the High grade immortal stones were he ended up finding Immortal Jade!

"This is rather good quality immortal jade." Lin Mu carefully checked the small jade vein.

It was embedded between a cluster of Immortal Stones on one side, and Deep Bowel Slate on the other side. It had a pale green color that mixed with white, showing that it was of a medium quality.

Still, it was Immortal Jade in the end and could be used for Immortal tools very easily. Lin Mu could also use them to make Jade Slips for himself if needed.

'I do need a better quality one. The Spirit Jade slips are now not enough to store information.' Lin Mu thought to himself.

The more documents and books Lin Mu gathered, the more notes he took. And it wasn't just those either, as he would also copy down information from other jade slips. Even if the Jade Slips had a large capacity for such information, there was still a limit to it.

So far, Lin Mu had been using multiple jade slips to overcome this, but it was now becoming inconvenient. Rather than that, he reckoned he should simply refine a new jade slip that was specifically built just to store a large amount of information.

'If I remove the communication function and analytical functions, I should be able to improve the storage capacity by several times.' Lin Mu thought to himself.

The runes needed to make the communication jade slips took a lot of space after all, and consumed a lot of data capacity of a jade slip. This also depended on the range of communication too.

The longer the range, the bigger the formation that would be used for it.

But since Lin Mu simply wanted to make a jade slip for information storage, he wouldn't have to bother with the other formations. He thought about what improvements he could make to the jade slip while continuing to mine the Immortal Stones.

Extracting the Jade vein was very easy for him and had taken less than a minute for him. All he needed to do was capture the right dimensions of the vein and simply use meld to cut it out

It didn't matter if he also cut away a part of the Deep Bowel slate along with it either. He could remove it later on and had no need to do it right away.

Lin Mu repeated this with other materials too that were embedded in the rocks or encrusted with the immortal stones.

The only time he couldn't use that method was when the resource he encountered wasn't a material but rather an Immortal Herb.

When that happened he would have to first identity what kind of Immortal Herb it was before carefully extract the Immortal Herb using the right method. After all, different immortal herbs had different requirements for harvesting as well as storage.

Some couldn't have their roots damaged, while some needed to be kept damp. There were countless different conditions that applied to different herbs, thus Lin Mu needed to be well aware about them.

Thankfully, the Immortal Herbs he encountered weren't any obscure ones and he easily identified them all before storing them away safely for later.

In all, Lin Mu gathered over a hundred Immortal herbs here.

'Seems like this place is more suitable for Immortal Herbs than the previous mine.' Lin Mu thought to himself.

So far he had come across more immortal herbs than other materials and ores showing that the conditions of this mine favored herbs.

It was still good for Lin Mu and he didn't complain about it. Gathering all he could, Lin Mu continued to mine the Immortal Stones and eventually reached the core area of the mine.

~huu~

Taking a deep breath, Lin Mu paused.

"This will take some precision work…" Lin Mu muttered as he gazed at the interlacing Immortal Stones.Published by Nôv'elD/rama.Org.

In this part, The Peak Grade, High Grade, Mid Grade Immortal Stones were mixing up, making it hard to separate them directly.
