Lin Mu was a bit shocked after reading the letter, as what it mentioned was nothing but the missing disciples and junior elder Fa Shiu of the Tri cauldron peony sect. Apparently, they were supposed to reach the city a week ago but still had not appeared.

This was the reason why the disciple was writing a letter to the sect, to inform them that they had not reached here yet.

'So they do not know about them either and that Junior Elder Fa Shiu is not here either. That ticks of another thing from my list. At least now I don't have to wander the city scouring for him.' Lin Mu thought.

Lin Mu stayed there on the roof till the disciple finished reading the letter and rolled it up. After that, the disciple melted some wax with the candle that was burning on his table and poured it on the seam of the letter. He stamped the seal of his sect on it and let it cool down.

After that, he saw him store the seal away in the drawer and leave the room. Lin Mu thought of following him, but then stopped. As soon as the disciple was gone, he came down and opened the drawer that had the seal kept in it.

"Just as I expected, there is more than one seal here. They shouldn't mind if I take one of them, I killed a servant anyway. They will eventually discover that.

" Lin Mu muttered to himself.

Having made his decision, he picked one of the seals from the drawer and stored it in his ring, before sinking into the floor using phase. Lin Mu had been continually using phase for more than an hour now, along with his other skills. This had led to quite a lot of consumption of his spirit qi.

This was the first time Lin Mu was using them so much.

After having sunk down into the ground, Lin Mu followed the place where the disciple was heading towards.

"As I expected…

" Lin Mu muttered to himself.

The disciple went to the elder that was meditating in the private room. Lin Mu stayed a sufficient distance away from the room as he was unsure whether the elder will scan the area with his spirit sense. Lin Mu knew that he was a nascent soul realm cultivator and that his spirit sense would be quite strong.

There was a high chance that he could be found thus, he wanted to be a sufficient distance away from there just in case he had to escape using Fade. Lin Mu held his breath and continued observing the room using his spirit sense.

~Knock~Knock~Knock~

The disciple knocked on the door gently and spoke.

"It is me elder, Quan Hong. I finished the report you asked me to write.

" The disciple spoke.

Since Lin Mu could fully touch the people with spirit as he could be found out, he waited for sounds instead.

"Come in,

" The elder spoke.

~Phew~

Lin Mu let out a breath, seeing that the elder had not used his spirit sense. The door slid open and Quan Hong walked in, before kneeling in front of the elder.

"Here's the report, elder. You can send it now.

" Quan Hong spoke.

"Good job,

" The elder simply replied before waving his hand, telling the disciple to leave.

Once the disciple was gone, the elder looked at the letter for a few seconds. Lin Mu could feel the fluctuations of spirit qi and immediately withdrew his spirit sense back as he realized the elder was using his spirit sense to scan the letter.

"You can read using your spirit sense like that?

" Lin Mu questioned in his mind.

"Yes, as long as your spirit sense is strong enough, it doesn't matter if there are multiple layers of paper on it. The elder is in the nascent soul realm, thus his skill with spirit sense should be quite good. Doing something like this is a piece of cake for him.

" Xukong answered.

Lin Mu nodded his head and kept on watching. After being done with the letter, the Elder stood up and went to a cabinet that was kept in the room. Lin Mu had not paid much attention to this cabinet before, but when the elder opened its door he felt the spirit qi fluctuations coming from them.

The elder then placed the letter in the center of the cabinet and closed the door. He placed his hand on a pattern that was carved on the top of it and closed his eyes. Strong waves of spirit qi emanated from the elder, and his full aura was released.

This was the first time Lin Mu was feeling the aura of a nascent soul realm cultivator. Still, while it was quite strong, it felt minuscule to Lin Mu as he couldn't help but compare it with old man Jing Wei's aura. He didn't even bother comparing it with senior Xukong, as that would be ridiculous.

The patter carved on the cabinet glowed, and then suddenly Lin Mu felt the spatial fluctuations coming from it.

"Is that a…

" Lin Mu muttered.

"Yes, that's a teleportation formation,

" Xukong confirmed.

Lin Mu nodded as an idea came to his mind. He continued watching and focused on the spatial ripples that were spreading in the area. Wherever the ripples went, Lin Mu felt as if layer upon layer were revealed. These layers were nothing but the fabric of space.

Lin Mu could sense a mass of energy coming from the cabinet and traveling through the spatial fabric while creating a path. It was not traveling in a straight path, but rather a very complex and winding one. Seeing its speed, Lin Mu was a bit surprised.

"Is a teleportation formation really this slow?

" Lin Mu asked.

"It's a low grade one and is being manually activated. It hasn't even sent the letter yet, right now it's only forming a spatial transmission channel.

" Xukong informed.

The elder kept pouring his spirit qi into the formation for about two minutes before he stopped. The pattern carved on the cabinet continued glowing even after the elder lifted his hand from it. Lin Mu could feel the mass of energy getting farther and farther away from the courtyard.
