All of these formations were located in the individual residence and then connected to the main spirit Qi gathering array of the sect.
Lin Mu continued observing the network while absorbing spirit Qi and sensed the different concentrations of spirit Qi in different channels.
"Oh? Some of those 'channels' have a higher concentration of spirit Qi while some have a lower concentration." Lin Mu muttered to himself.
"Wait a minute! It's one of these types, huh." Xukong suddenly said upon seeing what Lin Mu had just observed.
"Did you figure out something senior?" Lin Mu questioned.
He knew that if Xukong had reacted like this, there was likely something important or beneficial that he had found.
"Yeah. The formations that they are using for different types of residences, it's actually the same." Xukong spoke.
"What do you mean, senior?" Lin Mu questioned, unable to understand clearly.
"It means that the concentration of spirit Qi is determined by this limiter formation. If you modify it, you will probably be able to obtain the same effects you would see from an elder's residence." Xukong explained.
"Really?" Lin Mu said with his eyes wide.
"Yes. Follow my instructions and it should work." Xukong said, before explaining a few steps to Lin Mu.
Lin Mu carefully listened to all steps and made sure that it was safe before actually proceeding with it. He definitely did not want the sect to get alert about a spy being in their sect.
It was already nighttime and it took Lin Mu two hours before he was able to modify the limiter formation according to Senior Xukong's guidance.
But it was here that he made a mistake.
~WEENG~
"Oh no!" Lin Mu only had a moment to say this before a dense wave of spirit Qi knocked into him.
Lin Mu was barely able to hold his ground or he would have been knocked far back into the wall.
~whoosh~
It was as if a fire hydrant had been broken as the spirit Qi gushed out like a geyser.
"HAAA!" Lin Mu grunted before he was finally able to increase the setting of the limiter formation.
"Quickly absorb the spirit Qi into the ring!" Xukong urged.
Lin Mu realized that the danger was not over and raised his palm into the air, rapidly starting to store the spirit Qi into the mysterious ring. If Lin Mu let it leak into the surrounding, there was no chance that the people would not notice this.
~phew~
The dense spirit Qi that was almost visible to the naked eyes was then successfully stored in the ring.
~huu~
"Managed to do it… somehow…" Lin Mu muttered to himself as he wiped the beads of cold sweat that had appeared on his forehead.
Lin Mu looked into the ring and saw that all the spirit Qi which he had stored into the ring diffused into the surroundings. The spatial energy streaks that flickered in the sky were like hungry sharks as they hurriedly consumed the spirit Qi.
~Sigh~
"Seems like I can't use that spirit Qi, anyway." Lin Mu muttered to himself.
"The spatial energy streaks in the ring are of a far higher quality than normal spirit Qi. There is no way they would allow something of such low quality like this to stay here." Xukong explained.
This was new information to Lin Mu, as he had not expected this kind of property to be a part of spatial energy. The only instance when he had stored foreign spirit Qi in it was when he absorbed the spatial attribute spirit Qi from the spatial fissure that he had fixed in the Myriad Armament Canopy abode.
But even that was only able to stay in the ring due to its properties matching those that of the spatial energy streaks.
Lin Mu didn't relax now though. He spread his spirit sense around to check for any anomalies. He wanted to see if anyone had sensed this or not and luck seemed to be on his side this time.
"Slowly raise the limiter as you increase your absorption speed. That way you will not leak any wisps of spirit Qi outside." Xukong advised.
"I understand, senior…" Lin Mu said before he modified the limiter formation again.
This time he had better control and was able to slowly raise it. He then chanted the severing heart sutra and started absorbing the spirit Qi at a rapid pace. Lin Mu raised the limiter by one percent at regular intervals or whenever he felt that his pace of absorption matched that of the emission of spirit Qi.
It was an hour past midnight and Lin Mu had raised the limiter to 40% of its maximum limit.
For outer court disciples, this limit was set to 5% while for those that were in the inner court this limit was set to 20% instead. In the inner sect, there were a few higher quality residences where this limit was set to 30% instead.
Lin Mu had seen these formations in the residences of the core disciples as well and for them, this limit was set at 40% which was currently what Lin Mu was using.
"I think I can tolerate even more…" Lin Mu muttered to himself before raising the limit once more.
Now the limit was at 50% which was the limit set for elders. This was also the maximum standard limit in any of these formations, as going beyond this level could affect the supply of spirit Qi of other nodes.
Lin Mu did not go beyond this and fully absorbed the spirit Qi that was coming from the mat.
'If I had something like this before, how fast would my pace of cultivation be?' Lin Mu wondered.
He also thought about what would happen if he tried to use this formation in addition to the Well of Slumber Bloodline ability.
"That would probably make this formation unstable and eventually drain the spirit Qi springs below this mountain. We've already seen the capability of the Well of Slumber, that bloodline ability is no joke." Xukong hypothesized.
