Bai Rouyun was deep in cultivation the entire night, and the pill's efficiency had still not subsided as the sun broke through the horizon the following morning.

Bai Rouyun was not feeling worried about not attending class. The teacher had already made it clear that he would teach them nothing, and thus she thought it a waste to not continue cultivating.

During this night, she had touched the threshold of the Acquired Realm's Heaven Tier.

The path of one's cultivation was split up into realms. Each realm had its own rules for the tiers and layers, and the Acquired Realm was split up into the tiers, Earth, Sky, and Heaven.

These tiers were further split into initiate, mediate, and advanced.

When one had reached the Acquired Realm, Heaven Tier, and Advanced layer, then, if they had enough talent, then they could continue to break into another realm, the Innate Realm.

The Innate Realm was much different from the Acquired Realm. It was split into colors, the seven colors of the rainbow, with Red being the lowest tier, followed by Orange, Yellow, Green, Blue, Indigo, and Violet.

These tiers were not split into initiate, mediate, and advanced as they were in the Acquired Realm; instead, they were divided into seven layers.

At the Innate Realm, Red Tier, First Layer, the Qi that one commanded had a very weak red hue, but it grew stronger as one reached the Second Layer. This continued up until the Seventh Layer, where it was so strong that everyone who saw it could sense the power fluctuations that came from the Qi.

When one then reached the Innate Realm, Yellow Tier, First Layer, the Qi would once again only contain a slight hue of yellow; the intense red light would have vanished alongside the previous tier.

Although the yellow hue was much weaker than the red in terms of glimmer, the power that one could command with the yellow Qi was many times more dreadful than what the red Qi could.

So although it might look weaker, the power that each upgrade brought was in no way to be taken lightly.

After the Innate Realm came the Ascended Realm, Bai Rouyun had never reached this level in her past life, and Xiao Bao was also unwilling to tell her much about it. Hence she was still unable to know what kind of cultivation system was used in that realm.

However, she was not in a rush. Cultivation was a step by step process, and looking too far ahead would just cause problems for the current progress, and this was not something she was willing to see.

She was not even at the Innate Realm yet, so why begin considering the Ascended Realm?

She reeled in her wandering mind and began focusing on using the final medicinal properties of the Heavenly Absorption Pill to boost her cultivation base as much as possible.

After using this pill, she would not be able to consume another for quite some time, as she had to get used to the boost in strength she had gained, and she also had to solidify the foundations that would be slightly shaky after a rapid advance.

She had refined eleven pills, but she had only consumed one so far, leaving ten in her hands. Although she was not going to use them just yet, she had no intention of selling them, and instead, she left her room and went to look for Little Chu.

Little Chu had been given the tedious task of protecting her. She was never in danger, spending every day at the institute or in her room cultivating, so while Li Moyun's other subordinates were living exciting lives, his was dull and boring.

Since he never complained about the task he had been given, Bai Rouyun felt that since she had refined something good, she might as well share it with him.

Especially since it would take her a long time to consume all these pills.

"Little Chu?" Bai Rouyun was not an extremely patient person, and as soon as she left the room, she called for him. She did not yell loudly, as she knew that there was no reason for this, but she still raised her voice slightly, so that the poor guard could know that she was looking for him.

Not long after, Little Chu appeared next to Bai Rouyun. He no longer complained about his new name; he had entirely accepted that he was now 'Little Chu,' and looked at her in confusion. What was the purpose of her summoning?

Bai Rouyun took out two jade vials from her qiankun bag. She opened one, and it was empty, "hold this," she said as she showed it into Little Chu's hands, causing him to feel extremely perplexed.

However, he was her servant, so he did not question her and just looked curiously at her actions.

She then proceeded to open the second bottle, and the dense scent of herbs wafted out of the bottle. The smell made it so that even just a whiff of it caused his body to absorb heaven and earth essence faster than usual, and his expression turned serious.

This was good stuff!

Bai Rouyun was not stingy with Little Chu. Since he was doing such a good job, she would share what she had, so she instantly poured five pills into the empty bottle within Little Chu's hands, and he stared at her in shock. Was this as he thought?

Bai Rouyun smiled at Little Chu and said, "this is the Heavenly Absorption Pill. It increases the amount of heaven and earth essence that you can absorb, and as long as you can refine it, it will be a great aid to improving your cultivation base.

"but keep in mind that these pills are all external resources, and while they can boost your strength, they bring with them some risks. Only take one and then wait some days before you take another, make sure to get used to the new levels of your strength when you have consumed one, and make sure you have consolidated your foundations."
