Lin Mu returned to the Shuijing Clan with Shuijing Mingzhu and settled in for a day of rest.

A room that had been given to him was rather luxurious. The bed was about four meters wide and three meters long, while a floating curtain surrounded it. More than twenty pillows were spread on the bed with each of them having formations imprinted on them.

Not just that, even the sheets had formations on them that made them more comfortable. The mattress had a gentle Qi channeling array that provided optimum conditions for a tired body to recover. Then there was one additional thing Lin Mu noticed. The legs of the bed had formations on them too, more accurately noise suppressing and vibration dampening formations.

There were six pillars in the bedroom that had elaborate floral designs mixed with geometric patterns that were the primitive shapes of formations. Refreshments and snacks like Immortal fruits, wine and tea were also kept in the room, making sure that one had the most comfortable stay.

The only thing that the room lacked was a bath, but Lin Mu knew that was only due to the fact that the courtyard had a hot spring for that.

With a room that was fit for a prince, Lin Mu couldn't really find anything to complain about.

"This is nice." Lin Mu muttered and let out Little Shrubby.

~shua~

The beast appeared and looked around the room curiously too.

"Is this our new place?" Little Shrubby asked.

"Yeah, for the time being." Lin Mu replied.

"It's big." Little Shrubby said. "Though not big enough to fit me." He added.

"Of course, it is made for human size in the first place." Lin Mu replied with a chuckle. "There's a garden too, you can go take a look." He added.

"Okay!" Little Shrubby said and quickly jumped out the window.

Having let out the beast, Lin Mu walked around the room while thinking of things.

He had been working on gathering as much information as he could from the library and had only finished it a day ago. He had condensed most of the information that was present in the books and had transferred it into the jade slip.

In addition to that, he had further expanded his base of knowledge of formations with all the discussions he had with the Head Elder. Lin Mu's brain had been stimulated for a decently long time, and while he didn't necessarily need to sleep, he still had other things he wished to do in the Sleepscape.

'May as well, rest the body while I check some things out.' Lin Mu thought to himself as he sat down on the large bed that could accommodate over ten people if need be.

Lin Mu didn't sleep right away, instead he just sat surrounded by the fluffy pillows and pondered about all that had happened today. He had learned a lot of history of the Rust Sky World from Elder Pear and he could fill in the gaps in his knowledge.

Time passed quickly without Lin Mu knowing, and he fell asleep automatically. But he did not enter Sleepscape as his mind had entered deep sleep.

It was clear that his body had chosen to sleep instead. This was rare, as Lin Mu usually didn't lose control of his body like this. Especially after progressing in his body cultivation, as it improved overall control of the body.

Still, his body only stayed in a deep sleep for four hours before he woke up in the Sleepscape.

"Huh?" Lin Mu opened his eyes, feeling a bit disoriented. "Wasn't I going over the history of the Rust Sky world?" he muttered in confusion.

"You're awake." Lin Mu heard Little Shrubby's voice.

The beast was curled up next to him and had arrived here along with him too.

"What happened?" Lin Mu asked.

"You were sleeping when I came back." Little Shrubby answered. "I called, but you didn't wake up so I just waited."

"Huh… I actually fell asleep…" Lin Mu furrowed his brows, wondering if the time for the Well of Slumber to activate had come closer. 𝙛𝒓𝒆𝒆𝙬𝒆𝒃𝓷𝙤𝙫𝒆𝓵.𝒄𝙤𝒎

It had been nearly ten years since he had fully let the Well of Slumber activate. And that was when Lin Mu had first assimilated the bloodline of the Great Slumber Bear.

After that, it had activated a few times, but it had been on a minor level. For example, when Lin Mu had crashed into the Rust Sky world. He had been asleep for a while too.

'The Great Slumber Bear's bloodline hasn't had a full chance to activate for a while, so perhaps it is finally close to it.' Lin Mu reckoned.

His falling asleep without his control was a signal to that. Lin Mu had learned about the Well of Slumber and knew its period of sleep could extend to over a hundred years or more. It was also unpredictable, as such it was best if he was ready for it.

'Hopefully, I don't enter sleep before the expedition…' Lin Mu thought to himself.

He wouldn't mind it after that though, as he would be free of obligations. Plus, it would give him the time needed to further his formation and other skills.

"Well, I intended to come here anyway, so it's fine." Lin Mu said and got up from the ground.

He had appeared under the Immortal apple tree as always, and the tree gladly let its trunk be used by Lin Mu.

"Thanks," Lin Mu spoke to the tree and walked towards an empty space in the Sleepscape that was between the Immortal apple tree, the Violet Mystic Life Tree, and the Wood Spirit Tulip.

"Hmm, this should be good enough." Lin Mu reckoned and got to work.

He put down a few formation flags before setting up pillars carved from Mid Grade Immortal Stones. He had taken out the massive chunks he had mined from the Immortal Stone mine, and cut them into ten pillars. He then set up the ten pillars in an square shape, with four pillars on the corners, four on the sides and finally two that were midway to the center of the square.

The formation flags turned into ashes and entered the pillars, making them glow.

"First step done." Lin Mu muttered before he took out multiple Light Elemental materials.

There were special gemstones that could amplify the light along with those that emitted cold ice elemental immortal Qi.

He then bound these two elemental materials to the two central pillars.

~SHUA~

Then he carved runes into the pillars, which connected the materials in a complex formation on its own. One of the pillars turned pure white, with a yellowish glow, while the second pillar turned ice blue in color.

Next Lin Mu worked on making the details of formations and summoned his Rune Shaping Brush.

~shua~

Lin Mu's Dao Shell appeared within which the Dao Embryo was floating.

"Time for you to do some magic," Lin Mu muttered, and held the Rune Shaping Brush.

He dabbed it against the Inkstone shaped Dao Shell and injected Immortal Qi into it while letting it absorb more and more of it.

Once he felt it was ready, Lin Mu started to draw runes in the air surrounding the pillars.

~WHOOSH~WHOOSH~WHOOSH~

The runes flew to the pillars and stacked on top of them, making complex moving designs.

Lin Mu continued to work for about two hours like this, making rune after rune and merging them into the pillars. He didn't have success all the time either, as many of the formations continued to crumble and break.

'This is the first time I'm making this… there's bound to be mistakes.' Lin Mu thought to himself, finding ways to improve himself.

Thankfully, the ten pillars weren't damaged at all due to their dense structure and Lin Mu could afford to make mistakes.

He repeated it until a formation Array he had never seen before was created.

~HONG~

The formation array materialized over the pillars, letting them act as posts while a tent like structure was created.

"Light Spill Greenhouse Formation Array!" Lin Mu smiled upon seeing his success.

This was a formation array that was used by various herbalists and alchemists to grow immortal herbs and other plants. It was part of a broader group of Greenhouse Formation arrays and had been modified by Lin Mu to be suitable for a particular plant.

It was for none other than the Snow Glass Pear Tree!

Since it needed Light Elemental Immortal Qi to grow, while having slightly colder conditions, Lin Mu made the Light Spill Greenhouse Formation Array.

It showered the area with Light Immortal Qi while also having an inbuilt thermal control which could also chill the area. With this, he had made a suitable area for the Snow Glass Pear Tree seeds to sprout.

Or at least that was what he hoped for.

~huu~

Taking a deep breath, Lin Mu took out the Snow Glass Pears and carefully took out the seeds using Meld.
