Mortal: Even with a Heavenly Spiritual Root, I still have to try and get my hands on the Little Gree

After a sound transmission talisman was sent into the cave, Mu Yu soon saw Xin Ruyin activate the formation.

After more than twenty years apart, Xin Ruyin has now reached the mid-stage of Foundation Establishment.

Although it can't compare to someone with a Heavenly Spiritual Root like Mu Yu, this cultivation speed is still considered genius-level in Huangfeng Valley.

Especially considering the array at the entrance that could briefly withstand attacks from Nascent Soul stage cultivators, it's clear that Xin Ruyin hadn't neglected her research on arrays at all, aside from her cultivation.

"Although the Dragon Roar Body has many limitations, its cultivation progress is not slow."

Mu Yu spoke with some emotion, while Xin Ruyin seemed somewhat helpless about it.

"If I could, I would rather give up this talent and be an ordinary cultivator."

"Uncle Mu's visit this time must be for those ancient formations that Ruyin has completed."

"But unfortunately, the Reversed Five Elements Formation that you value most has only been completed by Ruyin to about 50% so far."

"As for the other major formations, Ruyin has prepared quite a few."

"But even if it is only about 50% of the Reversed Five Elements Formation, if it can be set up in advance, it should be able to delay a Nascent Soul stage expert for a period of time."

"This has already been confirmed by Master Linghu."

Xin Ruyin didn't exchange pleasantries with Mu Yu for long before directly stating the current progress of the formation.

"Oh? It's actually effective against Nascent Soul stage cultivators?"

Upon hearing this, Mu Yu immediately became interested and began to learn more about Xin Ruyin from her.

Possessing a talent for seeking good fortune and avoiding misfortune, Mu Yu is simply a genius in miscellaneous studies; as long as he knows something, he can succeed at it.

But... that's only limited to being able to successfully make it.

Mu Yu himself did not have a high talent for deduce or create new formations.

To be more precise, Mu Yu can only know how to act based on his talent for seeking good fortune and avoiding misfortune, but he cannot create something entirely new out of nothing.

Mu Yu's only attempt at deduce formations was the Qingyuan Sword Formation.

The Azure Origin Sword Formation, which Mu Yu spent more than five years creating, is not only a half-finished product, but also has many limitations and flaws.

Now that Xin Ruyin, a genius in formations, is here, Mu Yu naturally wants to ask her for some guidance.

"Uncle Mu, can this... really still be considered a formation?"

When Mu Yu finished explaining his Azure Origin Sword Formation, he received this evaluation from Xin Ruyin.

"Um, sorry. That's not what Ruyin meant, but Uncle Mu's Azure Origin Sword Formation is really far removed from the concept of a formation."

"A normal sword formation requires several sword cultivators to set it up before it can be successfully executed. The most important thing about that kind of sword formation is the strength of the sword cultivators, and the formation can only play a supporting role."

"There is another type of sword formation, which requires the flying swords used as the formation materials to reach the level of sword heart clarity. In addition, it also requires a large amount of magic power, and most importantly... a sword formation diagram as an aid."

"The effect that Uncle Mu wants to achieve is probably the latter."

"However, although your Green Bamboo Bee Cloud Sword is made of special materials, it has just been forged and has not yet undergone sufficient nurturing and tempering by the primordial spirit. Relying solely on its materials and flying sword abilities..."

"There's no sword formation diagram yet..."

"Under these circumstances, it's nothing short of a miracle that Uncle Mu was able to unleash the sword formation, and... the effect is quite good?"

Xin Ruyin stared at Mu Yu with disbelief, as if she had seen something out of the Arabian Nights appear before her eyes.

Upon hearing Xin Ruyin's description, Mu Yu felt a wave of dizziness wash over her.

Although I already knew that my Azure Origin Sword Formation was only a half-finished product, this was still a bit too outrageous.

As for the miracle Xin Ruyin mentioned, it naturally relied on the effect of her talent for seeking good fortune and avoiding misfortune.

I don't care about formations or anything like that, I don't really understand them anyway. Since doing this is auspicious, I might as well do it.

As for the principle behind it... I don't know!

Mu Yu wasn't exactly an expert in formations; he only knew how to set up and break some formations.

In the eyes of ordinary cultivators, Mu Yu knew how to set up formations and how to break them, so he should be considered a formation master.

In reality, Mu Yu wasn't even very proficient in some of the most basic principles of formations; he only had a slight understanding of them.

"Alright, there's no need to explain to me that I don't understand formations."

"Your next task is to work with me to perfect the Azure Origin Sword Formation."

"As long as the Azure Origin Sword Formation can be perfected, I will provide all the pills you need to reach the Core Formation stage, in unlimited quantities."

Mu Yu, being wealthy and powerful, offered Xin Ruyin a reward she couldn't refuse.

……

In the following period, Mu Yu began to work with Xin Ruyin to improve the Qingyuan Sword Formation, while occasionally receiving the spoils brought back by the people from Huangfeng Valley.

One person enjoys the diligent service of an entire sect; this is the treatment a sect disciple should receive.

Even if those poor, independent cultivators have high cultivation levels, they still have to go out and deal with all sorts of miscellaneous tasks on their own.

He flipped through the various sword manuals that the people of Huangfeng Valley had found for him, and every now and then he would choose an auspicious one from the many options listed by Xin Ruyin.

In short, with the blessing of Mu Yu's talent for seeking good fortune and avoiding misfortune, Xin Ruyin's skill in array formations progressed exceptionally quickly.

After all, in Mu Yu's eyes, there were almost no wrong options.

For the first time, Xin Ruyin experienced the feeling of creative exhaustion.

Despite pushing herself to the limit, Xin Ruyin managed to perfect the Qingyuan Sword Formation in just over five years.

First, Xin Ruyin abandoned Mu Yu's method of quickly setting up formations.

Because there is no way to quickly set up an array. Even if you manage to set it up, it's just a paper tiger that wastes Mu Yu's magic power.

Secondly, because Mu Yu possessed too many Green Bamboo Bee Cloud Swords, with his Core Formation stage cultivation level, he could only control them all for a very short time.

To solve this problem, Xin Ruyin designed a special array that needed to be refined in advance, similar to a special one-time magic weapon.

In addition, this array diagram needs to be inlaid with a full nine high-grade wood-type spirit stones in order to unleash its strongest power.

Nine high-grade spirit stones are a price that most Nascent Soul cultivators in Tiannan cannot afford, so the array diagram that Xin Ruyin initially designed was just an idealized assumption.

The true array is activated by seventy-two mid-grade spirit stones, which can reduce Mu Yu's mana consumption by about 50%.

Xin Ruyin was unaware that Mu Yu's storage bag at this moment contained more than a hundred high-grade spirit stones, most of which were wood-type. This was the harvest from only five years of mining on Biling Island.

(In the later part of the original novel, Han Li casually exchanged twenty or thirty high-grade spirit stones in a market near Biling Island, so the amount of spirit stones in the giant spirit stone mine on Biling Island is correct.)

If Mu Yu were to mine all the spirit stones on Biling Island, he could probably buy the entire Tiannan region.

Of course, this is all predicated on the availability of sellers.
