The Cultivation Method of Junior Sister is Unscientific

“This sword is named Tai’a,” said Cang Li’s spectral image, a sheepish expression crossing his face. “I forged it when I first began learning the art of weapon crafting. I left it here because of its unique property.”

“At the time, I used two extremely opposing types of ore to forge ten swords consecutively. This is the tenth and only successful one.”

Yun Jin gazed at the Tai’a Sword.

Half of the blade was white, the other half black, with a circular yin-yang fish in the center.

It clearly embodied the concept of Taiji.

She had seen this Taiji imagery in many worlds.

In an advanced cultivation realm, she once witnessed an elderly man with long white hair and beard, wielding a single sword, balancing hardness and softness to fend off an army of 100,000 at the city walls.

That scene remained vivid in Yun Jin’s mind.

This was why the sword immediately caught her attention.

Cang Li continued his explanation: “This sword was forged using two precious ores, yet its grade isn’t high, merely reaching the upper yellow rank. Given the quality of these ores, it should have risen at least one major tier.”

“After studying the Tai’a Sword, I discovered it possesses an extremely rare growth feature. If reforged using a specific method, its rank will increase accordingly. Look closely at the Tai’a Sword’s blade, and you’ll notice a faint star. This indicates that the current Tai’a Sword is a one-star Tai’a. If you can continuously modify it, it will gradually become a two-star Tai’a, three-star Tai’a, and eventually, the ultimate nine-star Tai’a. At that point, this sword may not be inferior to those heaven-grade treasures! It might even reach saint or divine grade! My creations are never failures; they simply need time to grow!”

As Cang Li finished speaking, a hint of fervor flashed in his expression.

Yun Jin’s interest was piqued.

As she examined the Tai’a Sword, an inexplicable stirring arose in her heart.

A sword that could be modified and continually enhanced.

A sword that fused two extreme attributes.

Upgrading this sword would undoubtedly involve countless challenges.

But…

Yun Jin’s lips curled into a slight smile. She liked it!

Cang Li continued, “Although this sword has immense growth potential, upgrading its star level is extremely difficult. Firstly, despite being yellow-grade, it possesses the blood-binding function. Once bound, the sword and wielder become one, greatly amplifying its power. Secondly, after binding, only the owner can forge this sword. In other words, to upgrade the Tai’a Sword, you’ll need to learn the art of weapon crafting. Thirdly, to increase its star level, the higher the level, the more precious ores are required. Even I couldn’t afford the cost of upgrading it to nine stars.”

“I’ve placed this sword here. If you’re willing to use it, you can bind it to yourself. If not, when you come to the Kunlun Sword Sect in the future, I’ll gift you a better sword.”

“Additionally, beside the Tai’a Sword are the materials I’ve deduced for upgrading its star level. I’ve only calculated up to five stars. If it can be upgraded further, I can help you deduce the rest.”

With that, Cang Li’s form vanished completely.

Yun Jin’s thoughts stirred, and a sword materialized in her hand.

Along with it appeared a jade slip.

As Cang Li had mentioned, the jade slip listed all the materials needed to upgrade to five stars.

Many of these materials were completely unfamiliar to Yun Jin.

But that didn’t matter.

Even Cang Li’s plan would serve merely as a reference.

She had her system, after all!

As long as she invested simplification points, the system would naturally deduce the optimal plan.

The more Yun Jin gazed at Tai’a, the more she adored it.

Lately, she had been practicing sword techniques with discarded swords from her senior disciples.

She hadn’t found anything wrong with that.

But now, as she touched Tai’a’s cool hilt, she suddenly realized.

If she was to walk the path of the sword, she naturally needed a peerless blade to accompany her on her conquests.

Currently, Tai’a was far from being considered peerless.

But…

With her guidance, Tai’a would one day reach nine stars and become a true divine sword.

In her previous life, Yun Jin had never seen Ye Danxia use this sword. However, there was a period when she attempted to learn weapon crafting, possibly to test her aptitude for it. After discovering her lack of talent in forging, she abandoned Tai’a. Consequently, the Tai’a Sword remained dormant in a corner of the storage ring.

In this life, with Yun Jin at the helm, this long-forgotten treasure was destined to shine brilliantly.

“System,” Yun Jin said softly, “Scan.”

The system immediately began scanning, automatically collecting the information Cang Li had provided, then presented a more comprehensive scan result.

“Tai’a Sword: Upper Yellow Grade. Currently at one-star status. Main materials of the blade are Abyssal Yin Stone and Blazing Yang Stone. Yin and yang intertwined, opposing yet coexisting, extremely profound.”

Yun Jin’s gaze flickered, “What materials are needed to upgrade to two stars?”

The system then listed the materials Cang Li had specified, based on the previous information.

A total of five types of ore, which, when added, would upgrade it to two stars.

“Simplify,” Yun Jin attempted to simplify ten times.

The system optimized the plan, changing both the types and quantities of ores.

Yun Jin rubbed her chin, then asked directly, “How many simplification attempts are needed for the most perfect plan?”

The system’s mechanical voice responded, “233 basic simplification attempts.”

This was within Yun Jin’s capabilities.

Just that the number was a bit annoying.

However…

She did indeed need a suitable sword.

Once Tai’a was upgraded to two stars, it would suffice until she reached the Nascent Soul stage.

The two-star plan was essential.

“Perfect simplification,” Yun Jin commanded.

After deducting the attempts, the system presented the final plan.

This time…

Only two types of ore remained, and it indicated that once the star upgrade was successful, the Tai’a Sword would rise to mid-level Mystic grade.

Since the system claimed this was the most perfect plan, Yun Jin chose to trust it.

Then, without hesitation, she drew a drop of blood from her heart and infused it into the Tai’a Sword.

Black and white light flickered on the Tai’a Sword, then merged into the yin-yang fish.

A faint bloodline appeared on the yin-yang fish, which was quickly absorbed.

Finally, it emitted a resonant hum.

The binding was successful.

As Yun Jin gazed at the sword now, she naturally felt a spiritual connection.

With a mere thought, the sword was stored within her body, nourishing itself in her dantian.

A bound treasure could be nourished by its owner’s spiritual energy. The longer it was nourished, the more sentient it became.

Yun Jin repeatedly drew out and stored away Tai’a, playing with it several times before finally satisfying her curiosity.

With the Tai’a Sword in her possession, she had a new task.

That was to upgrade this sword to two stars before the sect-wide assembly!

Yun Jin murmured to herself, “It seems I’ll need to pay a visit to Spirit Tool Peak when I have time.”

Yang Hui, the master of Spirit Tool Peak, was an interesting character. On the surface, he was on good terms with Huo Lie from Divine Pill Peak. But in most situations requiring him to take sides, he remained neutral.

During the previous spirit field incident, he was one of only two peak masters who remained neutral.

Neutral, huh…

All the more reason to meet him.
