The sun had long since set and the night had creeped in.

The Serene Glass Valley had resumed its calm, after the previous day's chaos. After the disappearance of the heavy gravity at the Great Meteorite Wall, the elders of the Serene Glass Valley had to remedy the situation.

As such, they had gathered the power of all their people and set up defensive formations that would provide protection to the backside of the Valley.

At the same time, they were improving it and adding more arrays, intending to make it as strong as possible. After all, they didn't want even a fraction of a percent chance of someone sneaking in. They couldn't help but thank the heavens it was Lin Mu who had discovered the security breach first, instead of anyone else.

There were still many elders as well as the other junior members of the clan posted at the wall and were continually adding more formations to it. All of the seven clans of the Serene Glass Valley were hard at work, but inside the Shuijing Clan's peaks, the scene was a bit different.

"You're back, Head Elder!

" One of the elders in the clan hall saw the old man enter.

"Yes, we're finally done with the Great Meteorite Wall.

" The Head elder replied while looking around.

"Seems like you're done with today's lessons Elder Mian.

"

"The juniors have been motivated since yesterday, so today went well.

" Elder Mian replied.

"Though, is everything fine there now?

" The elder asked.

"For the time being yes, but we've got a long way to go I if we want to take the security to the peak level.

" Head Elder replied.

"This will be a long term effort.

" He added.

"I see… Guess the juniors will have more things to do then. They'll actually be applying their skills in real time.

" The elder who was part of the teaching hall stated.

"Indeed, this will be a good opportunity for them.

" Head Elder said before remembering something.

"Speaking of that… where is Daoist Mu Lin?

" he questioned.

"Daoist Mu Lin?

" Elder Mian furrowed his brows.

"Last I heard, he's been holed up in the Library with a thousand books flying around him.

" He spoke.

"Oh? What's he doing?

" The Head elder was a bit confused.

He had thought that Lin Mu would be reading there.

"The juniors were unable to tell but did see a formation working there. They said that Daoist Mu Lin is both reading and making a formation at the same time.

" Elder Mian answered.

"Strange… We were supposed to discuss things once I returned, but I guess he is still engrossed with his own things.

" Head Elder muttered.

"Do you wish for me to call for me?

" Elder Mian inquired.

"No, no… I'll just head there myself.

" Head Elder replied.

"I wish to see what he is doing with my own two eyes.

" He said before leaving the main hall.

~SHUA~

The old man flew across the peak at a great speed, leaving a gust of wind that shook the trees around the area. And since he was the Head Elder, he had no restrictions in where he could go. As such, he directly reached the top of the library, having sensed Lin Mu's presence there.

~shua~

He landed on a balcony, avoiding making too much noise. He had already seen the formation in front of Lin Mu, as well as the thousands of books that were floating around him.

'That isn't a thousand books though now… that is over ten thousand.' The Head Elder estimated.

His eyes went to the formation in front of Lin Mu and he tried to figure out what Lin Mu was doing. At first, he didn't get anything, but after using his immortal sense, he finally picked up on what was happening.

'He… He's processing them all?!' The Head Elder was stunned.

All the books that were flying around Lin Mu were actually being read by him with his Immortal sense, while the formation in front of him was automatically transcribing the relevant parts of information into a Jade slip.

Instead of copying the entire contents of the books, Lin Mu was condensing the essence of them all and extracting the core of all the information contained within them.

'To do this on a scale such as this… How far has he refined his Immortal sense and how strong is his mind?' The Head Elder was astonished.

Formation masters would often have to use their minds and split them into multiple tasks processors when they were making formations. As such, they were used to doing things like this. But what Lin Mu was doing was taking it to the next level.

'I can do this but for a junior to do the same… I can only imagine his skill with formations.' The Head Elder thought to himself.

He let Lin Mu do as he wished and simply stood there, observing him. The Head elder was interested in seeing just how many books Lin Mu could process this way and how long he would be able to keep it up. To most, doing something like this would tire them out mentally.

Even for the Head Elder doing this would not be a regular thing and he would avoid doing it to strain his mind.

'How is he able to keep his mind stable? Does he have no thoughts?' The Head Elder wondered as he gazed at Lin Mu's face, which was utterly calm.

It was as if even the sky falling would faze Lin Mu and he was as stable as a million year old mountain.

Of course, the Head Elder had no idea that Lin Mu wasn't doing this without any assistance. In fact, he was using the Calming Heart Sutra to help keep his mind calm while he continued to read and process the books.

The compendium Jade Slip that he had made, which had been deemed as a Legacy Treasure by Lu Xu and others, was being improved further. Lin Mu was now expanding the formation section of the jade slip and adding more and more information to it.
