After becoming one with Arthur, Margaret is not only very happy because she loves him but also because she feels incredibly powerful, something even better than she experienced when she reached the second grade of Apprentice Rank.
Like Nyx, Margaret also becomes addicted to Arthur's love juice, both for the taste and for the way it makes her body feel. He also feels the same regarding their love juices, so sex is clearly more efficient than any cultivation method they have tried so far.
Right now, Arthur has Nyx sitting on his face, giving him lots of love juices while Margaret swallows his seeds. At the same time that they revel in lust, his power grows even more, so neither Arthur nor the girls want to stop.
But while the trio has a lot of fun, Aria hears the moans from behind his bedroom door with a blushing face and an expectant expression. 'Are they going to do it all day? Is it that good?' Many questions arise in her mind.
Part of her does not want to disturb the happiness of her son and daughters-in-law, but Aria is so curious about everything related to Arthur and his abilities. She feels so close to fully understanding it that she cannot wait any longer and knocks on the door.
*Knock-Knock* The sound echoes inside the room, surprising the trio. "Darling~? Do you plan to spend all day in bed?" Aria asks in a loving tone.
She hears Arthur exclaim and quickly starts dressing inside the bedroom with the girls. A few seconds later, he opens the bedroom door with a proud smile on his face.
Aria's first expression upon seeing her son in shorts and Margaret behind him in panties and using his shirt is a penetrating gaze, but she ends up smiling. "I was feeling your auras... Baby, you reached the Fighter Rank, and Margaret, the fifth grade of Apprentice Rank."
"Yeah, that's amazing, isn't it?" Arthur pulls his mother into a tight hug; he is immensely happy to be able to become stronger with his lovers.
"This is actually unbelievable..." Aria comments while enjoying the hug. But her expression becomes more impressed as she looks at Margaret. "I feel your Astral Energy, it is stronger as it should be, but your Pond has much more Energy than expected..."
"What does that mean?" Arthur asks while Margaret thinks the same.
Aria quickly explains. "This is one of the main differences between people with powerful Lineages and ordinary people: the amount of Astral Energy that our bodies can support. Therefore, people with powerful Lineages take longer to reach high Ranks, but each advancement is more significant than for commoners, so someone with Lineage is always stronger."
Aria's words leave Arthur and Margaret thoughtful, but Nyx, sitting on the bed in her black dress, seems to know what's going on. "This is because what we did improves our bodies in many ways," she explains. "I could only feel it inside myself the first time, but yesterday, I saw all the changes in Margaret's body...
Arthur, Nyx, and Margaret also wonder about the same things. They spend the whole day trying to figure out what that heart can do, but only mental communication works now. And just as he and Margaret can use it, she can also talk to Nyx, and they can hear the same things; in other words, such ability opens room for a whole mental conversation between them.
Aria also conducts various tests to measure the capabilities of Arthur and Margaret. Their cultivation is really solid; in fact, as Nyx mentioned, their bodies are slightly improved; in Arthur's case, the amount of his Astral Energy is a bit higher than a Mystic Fighter of Royal Lineage should have, and Margaret seems slightly above the common Lineage but still far from the Noble one.
The benefits are not just in their Astral Energy, but just as Arthur's body is also stronger than it should be, especially his Astral Veins, which have evolved from the Iron stage to Bronze, increasing his strength and stamina.
Margaret also has many benefits in her constitution. Mages usually do not have improvements in their veins in the first ranks, and even in the late ones, it is just a side effect as their cultivation focuses totally on Astral Energy. But Arthur's seeds really made her whole body stronger and more resilient, just like a powerful Lineage does.
Nyx also undergoes a similar process, feeling stronger each time she has Arthur's seeds, but since she's his Astral Beast, her power is limited to his. She also has not yet discovered other instinctive abilities except the ability to create clothes with her Astral Energy and use it to boost him as she did when he faced the bandits and guards of the noble who attacked him.
Aria keeps working hard to help the trio develop their power and skills. It is evident that for Arthur, having sex is much more efficient than any cultivation technique she has ever heard of, so he and his girls do that several times every day.
But while Nyx and Arthur can do it for hours, Margaret gets exhausted in about half an hour; her body can not absorb so much of his seeds and transform them into her power. Aria can use such time to start teaching her about magic while Arthur continues his intensive training with Nyx.
The more Aria observes the result of their training, the more she is certain there are no side effects and only benefits. Therefore, she modifies all her plans for them to revolve around their new cultivation technique, allowing Arthur to have sex with Margaret and Nyx whenever their bodies are able to transform all their juices into power.
In this way, the days pass very quickly, filled with wonderful moments; Arthur and his girls are always horny, ready to start and end the day cultivating, while Aria tries to contain her jealousy and support them in their power growth.
Since the main process involves Arthur and a woman, Aria begins to call it Astral Resonance, and such a process seems to improve as they get stronger. But even as miraculous as it is, as Arthur and Margaret's bodies get overall stronger, they need more Astral Energy to advance in Ranks.
Margaret takes three weeks to reach the sixth grade of the Apprentice Rank, and her power again greatly improves.
And even doing Resonance with both Margaret and Nyx, Arthur needs a month and two weeks to reach the second grade of the Mystic Fighter Rank. That is still much faster than Aria expected since it could take more than a year to make such progress, even using rare resources with other cultivation techniques.
The days continue to pass like a blink of an eye, filled with sex for Arthur and his girls, and their bodies getting stronger and stronger. He also does not stop training his sword skills between the love sessions with Nyx as well as studying magic with Margaret and Aria, and playing with little Eve, too.
These are certainly golden days for the Fletcher family.
