Competition.

Ying Yue, who was still awake after witnessing this scene, smiled and joined the touching moment. Snuggling into their embrace, which made sister Yelena feel embarrassed and uncomfortable by her presence, Ying Yue thought and realized that her new sister had probably already made a one-way vow to master in her heart. Unlike Ying Yue, who always expressed her desires openly to master, sister Yelena likely preferred to communicate through actions rather than words.

While Ying Yue's impurity was merely another version of herself, sister Yelena truly became impure. Unlike Ying Yue, who had the ego to separate herself from those versions, sister Yelena had no such alibi or excuse, as she had willingly chosen impurity for the sake of survival. But impurity is still impurity, and Ying Yue knew that this sister of hers would go to extreme lengths, even beyond what she herself would do if ordered by master.

Even though he often reminded them that they were his servants and slaves and that he could do anything he wished, Ying Yue also knew that their master would never act in such extreme ways, as it was in his nature to follow the Dao. Just like the Dao, which nurtures all living beings with protection and care, even when it may seem cruel and heartless from certain perspectives, Ying Yue understood that their master was the same—harsh and ruthless in mindset, but merciful and compassionate in action.

As they slept together until sunrise once again appeared on the horizon, Ying Yue woke up to see sister Yelena blushing as master's banana was still inside her chakram from the night before, and she was trying to escape his sleeping grasp.

Giggling, knowing that as master's concubines they could enjoy his body whenever they wanted, Ying Yue simply shook her head, wanting to show sister Yelena that even when the heavens collapsed, master remained calm like a statue.

So, peeling off her dress, which hadn't yet followed the oriental custom since they hadn't been bought or created, Ying Yue, with her pomegranate open for sister Yelena to see, just pushed down her chakram to remain connected to the master's sword.

Seeing sister Yelena look at her in confusion, Ying Yue let her pomegranate rest on master's chest, still sounding sleepy. Once again, even when the heavens collapsed, there was nothing that could shake his mind when he was determined to do something.

Kissing master deeply and seeing he was still asleep, Ying Yue then turned around and gave sister Yelena a look, signaling that it was okay to use master's body however they wanted. Ying Yue saw sister Yelena nod in understanding before pointing from her cherry to master's kiwi. Understanding her meaning, Ying Yue shook her head, indicating there was a line they must not cross as master's concubines.

This was confirmed by master's words himself when Ying Yue had asked about such things years ago when she was still with Matriarch Margarita. One of the rules was not to have lovemaking sessions with one another's concubines, kiss each other, or engage in any romantic acts when master was not present to witness it since, according to him, he didn't want to create female-to-female relationships among his concubines, as it would break the promise of the one-way commitment he expected from them.

Because of this, when sister Yelena wanted to kiss her, as she was currently in the mood, moving up and down, Ying Yue gave her a stern look and stopped her mouth with a hand. Seeing Yelena suddenly shiver in fright, probably because she hadn't been told the rules yet and feared her relaxing home might be destroyed, Ying Yue moved closer to whisper the rules and explain what it meant to be master's concubine. Yelena sighed in relief after hearing the long explanation.

With that settled, while waiting for their master to wake up according to his wishes, Ying Yue kissed his kiwi with one hand while touching her cherry with the other, satisfying herself while imagining an intimate relationship with him. Although Ying Yue liked to swap with Sister Yelena, she decided to let her crybaby sister have her moment since it was her first day. 

However, once their master was awake, it would be an entirely different story, as Ying Yue planned to fight for the chance to ride his body. Knowing that if their use of their master's body wasn't properly scheduled, it could turn into a bloodbath among them, she decided to have a heart-to-heart discussion and deal with Sister Yelena later, once their master was awake to act as the jury.

As for why their master wasn't the one to impose the schedule and distribution of time, Ying Yue remembered he had explained that if he did, it would be seen as unfair favoritism. That's why it was better for the concubines themselves to establish the rules for scheduling and sharing his body, ensuring fairness and impartiality since they were the ones competing with each other. When asked about the extent of the competition and boundaries, Ying Yue recalled that their master had only sighed in distressed silence, indicating that everything from simple bets to killing each other was allowed.

Although confused at first, Ying Yue realized that this was the only way to keep them in check and prevent them from going to extremes since allowing everything also meant they would receive extreme punishments for their actions toward each other.

Because of this, Ying Yue and the other concubines didn't want to find out what the punishments were, thus creating an unseen social morality specifically for master's concubines. This fostered respect among them, even if they didn't like each other.

Thinking about all sorts of things while satisfying herself using master's body, Ying Yue saw master wake up exactly at 7 a.m. Unable to control herself any longer, she pushed sister Yelena aside, who was still enjoying the up and down of her chakram in blissful silence, to swap their positions.

Sister Yelena stumbled to the ground due to the sudden action, almost falling from the big flat rock they slept on, but master caught her. Ying Yue didn't care, knowing that when master woke up, he would calculate their distribution of love and how to give it, especially since his calculations ensured there would be no discord among them later, as he was very good at satisfying all of them when awake.

Seeing sister Yelena look at her with resentment for interrupting her fifth climax, Ying Yue rolled her eyes, finally showing her true greedy nature. She no longer needed to care about the other sisters' opinions, knowing they would come to harmonize again using master's calculations.

Tian Xing, seeing both of them switch from friendly to competitive, pinched his eyebrows slightly in frustration, not wanting to imagine what it would be like if there were hundreds or even thousands of concubines. But he knew it was too late the moment he liked both Ciri and Margarita at the same time in the previous world.

Because of that, he had to continue if he didn't want to break his wife's heart, realizing that he only needed one woman, making his affection for Ciri at the time considered cheating. So, taking Yelena's hand, who was currently looking at Ying Yue with silent indignation, Tian Xing kissed Yelena deeply after a bit of calculation and proceeded to dance in combat and savor sweet fruits for two weeks straight without a break.
