Shirong looked at what clan Head Lu had brought him and Lin Wu did the same.

"Huh? A pill bottle?" Lin Wu muttered to himself.

"What are these pills for clan head Lu?" Shirong questioned.

"These are hair growth pills, young master. I thought since you will be demonstrating in front of so many people, it would do you no justice if you looked like this." Clan Head Lu answered.

Shirong had honestly forgotten about his hair by now and was not thinking of it. But now that clan head Lu reminded him, he thought that it would indeed be good if he grew his hair back.

"Thank you for being thoughtful, clan head Lu." Shirong replied.

"It's not a problem young master. Though I do not know if these will be effective on you. Certain pills don't work if the hair loss is caused by a technique." Clan head Lu stated.

"I'll try and see it anyway I guess," Shirong said before opening the pill bottle.

The pill bottle was rather small and only contained a single pill in it. Shirong ate the pill and waited for its effects. But his hair did not grow out directly.

"Hmm… seems like it's not working." Clan Head Lu furrowed his brows.

"My hair loss was caused by a cultivation technique, so it may take longer. Even if it has not grown any hair yet, I can feel the tingling sensation on my head and face." Shirong replied.

"Alright then young master. Hopefully, it is done by tomorrow. I'll take my leave for now, if you need anything you can ask the servants." Clan head Lu said before leaving the courtyard.

"So these are the people who will be a thorn in our path later on…" Shirong muttered to himself as he read through the jade slip that clan head Lu had given him and rubbed his head.

His head and face were now a bit itchy due to the pills and now that Lin Wu took a closer look, the area where his eyebrows were supposed to be was getting darker.

"Oh? It seems like the hair growth pills are taking effect, his eyebrows are already growing below his skin." Lin Wu muttered.

'Though I wonder by how much does this pill accelerate the growth of hair? Hmm… normal eyebrows when shaved offs completely take about four to six months to grow back and if I estimate using that, the growth rate is a few hundred times that normal.' Lin Wu calculated.

Shirong had finished looking through the jade slip and had now decided to take some good night's sleep. He had been busy cultivating and making sure his body was in the optimum condition for his breakthrough in these past few days and thus had not slept at all.

Even though cultivators did not need to sleep as much as common humans did, it did not mean that they could give it up completely. While cultivating could replace sleep up to a certain extend, actual sleep was still needed for them to restore their mental condition and fatigue.

Thus Shirong laid down on the bed and slipped into a deep slumber. Lin Wu checked his condition and body to see how everything was working.

The system had increased its understanding of the unknown energy that coursed through Shirong's core and had reached the preliminary conclusion that it was a much higher version of the spirit Qi.

It was destructive to most cultivators and Lin Wu could only guess that the ones that were above the currently known cultivation realms could handle a strong energy like that. But the system was still able to handle it somehow and even Shirong's core seemed to have adapted to it in a way.

When Shirong increased his body tempering realm cultivation, his Dantian had expanded as well. This lead to an increase in his spirit Qi capacity and in turn his core could expand once more.

If one considered his original talent, Shirong was nearly thrice as better than then. Lin Wu had not expected that furthering the body tempering realm cultivation would have an effect like this and wanted to do it as well.

But then the system told him that his situation was rather unique. The aim of the body tempering realm was to make one's body more adapted to the spirit Qi and cultivation. But in Lin Mu's case, his body had been completely recreated by the system, which meant that it was inherently suitable for cultivation.

In other words, what Shirong had done, he had already achieved that due to the system. Still, the system's analysis had not ended and it would only go on further helping it further the analysis of the other cultivation techniques.

'Hmm… since Shirong is asleep and the rest of the people are busy working for the tribulation platform, I should take advantage of this.' Lin Wu thought.

"System, re-scan the city and the area around it. Check for the people's position and see if it's a viable option to visit the underground area under the Lu Clan mansion." Lin Wu ordered.

Lin Wu had this on his list for a while and had wanted to check it out but was unable to do so, because of having to go to the Millennium forest with Shirong.

Another benefit that he had was he now didn't have to worry about distance as much. If it really was an emergency, he could teleport the Avatar from the city back to the tomb and then next to Shirong.

While this would take up about 2000 units of spirit Qi, it was still an affordable cost to Lin Wu that he didn't mind paying for an emergency.

"Well then, let's head out." Lin Wu said after checking the map. He shrank his body and appeared in the real world.

He crawled out of the bedroom and dug into the ground before traveling to the underground area under the Lu clan mansion. The outer formations were not a problem for him, since the system already had the visual interface for them.

Though when he reached the outer area of the underground hall, he came across a problem.
