Mortal: Fifteenth Realm Sword Cultivator

Upon hearing this, Xin Ruyin's face did not show much emotion.

For her, foundation building was not an experiment, but a necessity.

Yan Ruyan's joking remark that she would never see Senior Lu again.

She didn't even dare to think about that possibility.

The last time?

How could I possibly accept this!

"Sister Ruyan, when do you plan to break through to the Core Formation stage?"

Upon hearing this, Yan Ruyan didn't keep her in suspense and slowly said, "Once your mind is stable, you can try to break through at any time. Tianxing City is so vast that I haven't had a chance to properly explore it yet. Breaking through from Qi Refining to Foundation Establishment only requires sufficient spiritual energy in the body, but breaking through from Foundation Establishment to Core Formation requires a clear mind and the ability to perceive opportunities, which is even more crucial."

"If you're not planning to go into seclusion right away, why don't we take a stroll around Tianxing City for the next few days? This city has a wondrous structure; each level is a world unto itself, layer upon layer, with mortals and cultivators mixed together. To be honest, I've always wanted to explore it."

Xin Ruyin's eyes brightened slightly, and she nodded. Yan Ruyan's suggestion suited her perfectly.

"After living in a cave for so long, it's really time to go out and get some fresh air, to experience the hustle and bustle of the world. It might even be beneficial to one's state of mind and understanding."

Yan Ruyan smiled, her beauty radiant and captivating.

"Then it's settled. However, since you've just reached the peak of Qi Refining, your Qi still needs to be stabilized. Let's go in a day or two."

Two days later.

Xin Ruyin changed into an elegant moon-white robe.

Yan Ruyan wore a light purple palace dress, her hair styled in a simple updo.

The two of them suppressed most of their spiritual energy fluctuations and took some precautions to avoid attracting unnecessary attention.

After breaking through layers of restrictions, the two stepped out of the cave.

The fiftieth floor of Tianxing City is already the residence of high-level cultivators, and it is located within the core area of ​​Tianxing City.

The environment here is serene, with pavilions and towers nestled among exotic flowers and rare herbs, and small spirit-gathering formations.

Various kinds of streaks of light rushed across the sky.

The two stood side by side on the same flying artifact, which carried them slowly downwards.

This flight was completely different from the one when Lu Jianghe brought them here.

At that time, the scenery around us was changing rapidly, and we hadn't even seen it clearly before we arrived at the next place, so there was no time to take a closer look.

It was only during this leisurely descent that they truly experienced the grandeur of Tianxing City for the first time.

The fiftieth level of the cave where they were located was just a tiny corner of this enormous city.

The further down you go, the wider your view becomes, and the more magnificent the scenery becomes.

Tianxing City is very high, and below this fiftieth floor, there are layers upon layers of swirling clouds and mist separating the city.

The two did not intend to explore the entire Tianxing City.

They lingered for several days in the first level, a place where humans and immortals lived together and where the atmosphere of everyday life was most vibrant.

During the process, there were no clichéd acts of blocking the road or causing trouble, nor were there any ignorant cultivators who coveted the beauty and stepped forward to harass her.

Tianxing City has its own operating rules and intangible order, especially in the area where the core of the Star Palace's power is located, no one dares to easily cause trouble.

Furthermore, the two traveled in a low-key manner, their auras concealed, making them appear just like ordinary female cultivators at the Qi Refining or Foundation Establishment stages, blending into the crowd.

After returning to their cave dwellings, Xin Ruyin and Yan Ruyan each went to their quiet chambers to prepare for another period of seclusion, aiming to break through to the next level of their respective cultivation.

Only half a month has passed.

The originally stable flow of spiritual energy in the secret room belonging to Xin Ruyin suddenly trembled.

As if subjected to an invisible repulsion, it spread outwards, causing the restrictive light curtain within the secret chamber to ripple slightly.

Not long after, a soft and long sigh came from the quiet room, carrying the relief of the dust settling and a hint of barely perceptible joy.

Immediately, the door to the quiet room slid open silently.

Xin Ruyin walked out slowly.

She was still dressed in that simple white dress, but her overall demeanor was completely different.

Qi Refining and Foundation Building may seem like a small step apart, but they are actually the initial leaps in one's level of life.

After the breakthrough, the cultivation can be temporarily put on hold.

One should not blindly cultivate if one's foundation is unstable, lest one have a high level of attainment but a weak foundation, like a castle in the air that cannot last.

Stepping out of the quiet room, his gaze fell upon the direction where Yan Ruyan was in seclusion.

The spiritual energy there was gathering and surging, and the atmosphere was far more magnificent than when I was in the Foundation Establishment stage.

It was clear that Yan Ruyan was already attempting to break through to the Core Formation stage. Given her Pseudo-Core Formation cultivation, the time she spent in seclusion this time would inevitably be much longer than his own.

Xin Ruyin wasn't in a hurry.

When I'm alone, my mind is inevitably in turmoil, so I simply find something to do.

The fiftieth level cave is spacious, containing not only alchemy rooms but also weapon-forging areas.

"The art of weapon crafting..."

Xin Ruyin muttered to herself.

She was already very familiar with this path, and now that she had a considerable amount of resources for cultivation, she began to have such thoughts.

Instead of wasting time, I might as well tinker with some small items. This way, I can continue to study the art of weapon crafting and also pass the time.

They were especially concerned about miniaturizing the teleportation array.

If successful, we will not be limited to large-scale formations.

Wherever it goes, it can create a portable array plate, supplemented by specific guiding signals and star positioning methods. Although it cannot achieve the exaggerated feat of traveling thousands of miles in an instant, it should be very useful for traveling between the inner and outer star seas.

Summer has passed and autumn has arrived, but fortunately, spring breezes still blow through the world.

Inside the weapon-refining room, Xin Ruyin was focused, holding a array plate in her hands that was filled with mysterious runes.

This is a completely miniaturized teleportation array that took three years of painstaking effort to create!

Just then.

A sudden tremor ran through the air, as if the entire space was being instantly tensed and stretched.

Immediately afterwards, an extremely dazzling azure beam of light shot into the sky, defying all the layers of restrictions!

Xin Ruyin was shaken and looked in that direction.

He then immediately put the array plate into his storage bag and flew out of the stone chamber.

When Xin Ruyin came outside, she saw that the source of the dazzling blue light pillar was none other than where Yan Ruyan was in seclusion.

This surge of spiritual energy lasted only a fleeting moment. Immediately afterwards, all the dissipated radiance and surrounding spiritual energy suddenly contracted and rolled inward, like a whale swallowing the sea.

Xin Ruyin held her breath and concentrated.

Generally speaking, as long as the resources are sufficient, even a cultivator with mediocre talent will eventually succeed in breaking through from the Qi Refining stage to the Foundation Establishment stage.

But he was attempting to break through to the Core Formation stage.

Even for those with exceptional talent like those possessing Heavenly Spiritual Roots, there is no guarantee of success; the possibility of failure still exists in the range of 20-30%.

This scene lasted for about the time it takes to drink a cup of tea.

Finally, the raging vortex of spiritual energy suddenly stopped, the strange phenomenon dissipated, and the previous calm was restored.

Xin Ruyin paced back and forth, her mind uneasy.

I wonder if Yan Ruyan has succeeded in her attempt to break through to the Core Formation realm.

Just as her thoughts were in turmoil.

A streak of azure light suddenly shot out from the quiet room, its speed as swift as a startled swan.

Xin Ruyin only felt a flash of light before her eyes. Before she could react, the light suddenly disappeared beside her, revealing her true form.

It was Yan Ruyan.

At this moment, she was dressed in a long, fitted black dress with an open neckline, her long hair was styled in a high bun, her skin was radiant and glowing, and her eyes were bright and clear.

The two women were equally beautiful, their looks were quite even.

However, at this moment, Yan Ruyan, who was in the Core Formation stage, exuded a more outstanding inner and outer radiance and majesty, and her intangible temperament was even more remarkable, firmly overshadowing Xin Ruyin, who was still in the Foundation Establishment stage.
