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

After returning to his cave, Mu Yu rested for a few days. Then, he used earth-遁 (earth-遁 is a technique of escape from the earth) to search for traces of the Gold-Eating Insects underground in the Xiaohuan Mountains.

Mu Yu had no patience to wait for Han Li's messy spirit insects to lure out the Gold-Eating Insects, so he directly used earth magic to enter the ground to search.

Using earth magic with wood magic is very strenuous, so Mu Yu specially crafted an earth magic artifact as an aid.

Even so, under the observation of Ming Qing Lingmu, Mu Yu still spent a considerable amount of time finding the Gold-Eating Insect.

However, the gold-devouring insect swarm they found was completely encased in a layer of stone shell, with no trace of its aura leaking out.

If it weren't for the Ming-Qing spiritual eye's ability to see inside, Mu Yu would probably have doubted that he had found the wrong thing.

After the stone shell was removed, the Gold-Eating Insect remained dormant inside the shimmering silver sphere, showing no signs of waking up.

Mu Yu had no idea how long this small clump of gold-devouring insects had been dormant underground, nor did he know how to awaken them.

If something unexpected happens, then the only gold-devouring insect in the human realm will be wasted.

So, after discussing it with Han Li for a few minutes, Mu Yu threw all the spirit insects, insect eggs, and the gold-devouring insect swarm in Han Li's hands, except for the white jade spider, into the white jade stone chamber.

At the same time, Mu Yu used magic to isolate the aura of the white jade spider.

Two months later, Mu Yu finally learned some good news from Han Li: the group of Gold-Eating Insects had devoured all the other spirit insect eggs and had now awakened.

At this stage, the Gold-Eating Insects are not of much use to Mu Yu.

Therefore, we need to feed it properly from now on.

At times like these, the monster flesh and blood that Mu Yu had previously stored in his storage bag came in handy.

The Gold-Eating Insects are almost indiscriminate eaters; whether it's the flesh and blood of a level 5 or level 7 demon beast, it's a feast for them.

After feeding it for several months, Mu Yu took out a five- or six-hundred-year-old Rainbow Grass that she had prepared beforehand, dripped half a drop of green liquid from the Palm Heaven Bottle, and threw it into the bottle while the Rainbow Grass was emitting its fragrance.

Soon, the gold-devouring insects, attracted by the fragrance of the Rainbow Grass, began to rampage and devoured the Rainbow Grass completely in no time.

Han Li's eyes showed a hint of surprise upon seeing this scene.

Although it was unclear what Mu Yu was doing, it was obvious that Han Li had developed some interest in this special spirit insect.

Mu Yu instructed Han Li to suspend the cultivation of Thunder Bamboo, and to use all the green liquid from the small green bottle every seven days to cultivate the Rainbow Grass he had brought back.

Since these herbs are hundreds of years old, only one drop is needed to release their fragrance, and sometimes even half a drop is enough.

This continued for more than three months until the gold-eating insects finally began to devour and kill each other, leaving only a few dozen insects, which then began to lay eggs.

After just one egg-laying, the number of gold-eating beetles surged to more than 1,500, and the newly hatched beetles also had some rice-grain-sized gold spots on their bodies.

After the new Gold-Eating Insects hatched, Mu Yu placed them back in the white jade insect chamber, allowing Han Li to continue cultivating the Thunder Bamboo.

Mu Yu, on the other hand, went into seclusion to continue cultivating the third level of the Great Evolution Technique.

The first two levels of the Great Evolution Technique posed almost no difficulty for Mu Yu.

However, starting from the third level, Mu Yu's cultivation speed suddenly slowed down.

If you include the free time when killing monsters, Mu Yu has probably been cultivating the Great Evolution Technique for more than two years.

However, in the past two years, Mu Yu has only mastered less than one-tenth of the third level of the Great Evolution Technique.

This speed is already considered very fast for ordinary cultivators.

But for Mu Yu, this was the first time she had experienced the difficulties of cultivation, and it was a trial she had never experienced before.

Moreover, these hardships will not disappear; on the contrary, they will increase as one's cultivation level rises.

After all, the Heavenly Spiritual Root only has miraculous effects before the Nascent Soul stage; after the Nascent Soul stage, the assistance it provides to cultivators is not so obvious.

The "hardships" that Mu Yu remembered were just everyday occurrences for ordinary cultivators.

"It's just a little time, I can afford to waste it."

……

Time passed by little by little, and fifteen years flew by in the blink of an eye.

During these fifteen years, Han Li completed the cultivation of the Third Revolutionary Yuan Technique, successfully returning his cultivation level to the late Foundation Establishment stage.

Mu Yu, on the other hand, completed the third level of the Great Evolution Technique five years ago.

In the five years following the completion of the third level of the Great Evolution Technique, Mu Yu began to study the forging method of the Azure Bamboo Bee Cloud Sword.

The forging of the Green Bamboo Bee Cloud Sword is not particularly difficult; it is simply a matter of forging a set of magical treasures. Although the quantity is a bit large, it is not considered difficult to forge.

After successfully forging the Azure Bamboo Bee Cloud Sword, Mu Yu was also very clear about its advantages and disadvantages.

Normally, a complete set of magical artifacts will have a main body, such as the common mother-and-child blades.

Complete sets of magical artifacts without a main body also exist, but those artifacts are more difficult to use, requiring significantly more spiritual energy and magical power.

However, because there is no main body, each piece of this set of magical artifacts can exert its maximum power without any reduction.

However, a natal magic weapon needs to be nurtured and refined by the cultivator's primordial spirit to make it more powerful.

Furthermore, the longer a natal magic weapon is cultivated, the stronger its power will be.

If the nurturing and refinement time is insufficient, then the natal magic weapon may not be as powerful as an ordinary ancient treasure.

However, with such a magical artifact that lacks a main body, the progress of a cultivator's primordial spirit nurturing and cultivating it will become extremely slow.

After all, other people only need to nurture and refine one magic weapon in their primordial spirit, while you need to nurture and refine a total of seventy-two.

Even with a complete set of magical artifacts, the process of nurturing and cultivating them will be ten times slower than for ordinary people.

For a complete set of magical treasures with a main body, things are a bit better in this regard. No matter how many sub-type magical treasures there are, the difficulty of nurturing and cultivating them is only two or three times that of ordinary magical treasures.

Of course, the Green Bamboo Bee Cloud Sword, made from Golden Thunder Bamboo, is strong enough at least in the human realm, and the time wasted in nurturing and refining it is nothing.

Once they arrived in the Spirit Realm, Qing Yuanzi also had a way to accelerate the nurturing and refining process of the Azure Bamboo Bee Cloud Sword.

That's right, it's that sword-planting technique!

Although there is a solution, Mu Yu is not willing to go to such lengths.

His situation is different from Han Li's. Han Li has four spiritual roots, so the attributes of cultivation techniques are not important to him.

However, Mu Yu possesses a Heavenly Spiritual Root and a special constitution called Wood Spiritual Body. If his natal magic weapon contains impurities or is not properly nurtured and refined, it will have a significant impact on Mu Yu.

Therefore, after more than four years of deduction and testing, Mu Yu deduced a brand-new method for forging the Green Bamboo Bee Cloud Sword.

If all goes well, Mu Yu will be able to solve two huge problems at once.

……

Several months later, after Mu Yu received Han Li's communication talisman, he saw seven jade ointment boxes on a stone table near the spirit herb garden.

Inside the jade box were seven fully mature golden thunder bamboo stalks that had detached on their own.

Han Li was currently busy working in the spirit herb garden, very diligently.

Although the other medicinal herbs planted were not nurtured by the green liquid in the small green bottle, they were still able to grow steadily in this herb garden.

"Han Li, I'm about to refine my natal magic weapon. Would you be interested in watching?"
