I'm determined to become an immortal!

As it turns out... He Sheng's idea was feasible, but the problem was not that simple.

First, to cultivate the "Ten Thousand Demons' Joint Transformation Technique," one must first select a high-level spell and cultivate it to perfection.

Only after this can one cultivate the "Ten Thousand Demons' Joint Transformation Technique".

"While the Time Leakage technique can indeed circumvent the fact that it utilizes demonic beast bloodlines, the problem is that it's only at the beginner level. Under its manipulation, the time rate increases by a factor of three!"

In short, it takes three times the general cultivation time to support the "Ten Thousand Demons Co-existing Divine Transformation Technique," which is equivalent to purchasing a suitable demon bloodline with time.

The problem is, this is just the beginner level. How much more time will be needed to go on to become more proficient?

In addition, there's the time required for the spell itself.

Clearly, the "Ten Thousand Demons' Joint Transformation Technique" requires a large amount of general cultivation time to sustain cultivation, and He Sheng's current general cultivation time is far from sufficient.

He Sheng shook his head, and could only put it aside for the time being.

"I need to finish what I'm currently dealing with as soon as possible, find a safe place, and begin my subsequent cultivation."

With this thought in mind, He Sheng's gaze fell on the Beast Taming Ring, where the bloodied and mangled Devouring Serpent, which had been blasted apart by the Gathering Water, was now recuperating.

He originally planned to use the Devouring Treasure Serpent to find the resources that Ji Yunlai had hidden, but the second-tier spirit beast was completely uncooperative and refused to communicate with He Sheng.

Given his severe injuries, He Sheng was truly at a loss as to what to do with him for the time being.

"Alright, let this treasure-devouring snake rest first, and we'll think of something else later."

The most urgent task is to hurry north to Tiandu Mountain and collect the corpses of those powerful demons; that would be a significant source of resources.

Thinking this, He Sheng picked up Kou Xiang'er and held her in his arms. After leaving the cave, he transformed into a streak of light and plunged into the Silver Sand River, going upstream against the current.

......

A few days later,

Within the Longevity Pool

He Sheng used the power of the "Ripples" technique to concentrate most of the toxins in the pool, forming a gray-black water sphere the size of an adult's head.

As a result, the water in the pool became much clearer, and the carcass of the centipede that had sunk to the bottom of the pool could be seen.

However, He Sheng didn't rush to retrieve the body. Instead, he looked at the gray-black water sphere in his hand and murmured:

"If I were to infuse the centipede demon's venom into the river water accumulated within the River Pearl, and then use it to unleash the Water Gathering Strike, in addition to the inherent power of the Water Gathering Strike, there would also be the power of the venom exploding, which should increase the power of the Water Gathering Strike even further, right?"

He Sheng acted on his idea immediately, taking out the River Pearl and using his magic power to wrap the gray-black water ball, gradually storing it into his magic artifact.

After finishing this task, He Sheng went down to the bottom of the pool to prepare to dispose of the centipede's corpse.

Cleaning up the corpses of demonic beasts is no easy task, especially for a second-tier demon like the centipede, which is a treasure trove. However, one must possess extremely specialized knowledge to identify the useful parts and use specific methods to process them into rare spiritual materials.

Otherwise, if things are handled carelessly, the perfectly good demon corpse might even turn into a pile of waste.

The hardest part of the centipede's head, its carapace, has been shattered. The most valuable parts are its pair of sharp antennae and its hooked mandibles containing venom glands.

If handled properly, these two can be comparable to second-grade high-quality spiritual materials.

However, the slightest negligence can result in the material becoming tainted or losing its essence, causing a significant drop in its grade; in severe cases, it can be rendered useless.

Simply put, the key to generating significant added value lies in whether one possesses the relevant professional knowledge and techniques for cooking ingredients.

It should be known that second-grade high-quality spiritual materials are worth tens of thousands of spirit stones.

A first-grade spiritual material is worth at most a few hundred spirit stones, and some low-grade first-grade spiritual materials are only worth a few spirit stones.

"Luckily, I was prepared!"

He Sheng looked at the water clock in his palm and saw that there was an extra drop of water in the [Art] section.

[Tier 1 Mid-Grade Refiner: 829/2000]

(Total cultivation time: four years, one month, and sixteen days)

He Sheng obtained the "Secrets of Refining Weapons in Tianyue Mountain" from Wu Feng. After mastering the basics of weapon refining, he devoted all the remaining five years of general training time to it, which is how he achieved this result.

Like array formations, the time rate for crafting weapons is 1.2 for the low-grade first tier and 1.5 for the mid-grade first tier.

This is why, after more than five years of investment, the actual effect was only achieved in a little over four years.

"To cultivate the 'Divine Artifact Bottle Forging Technique,' one must reach the level of a second-tier weapon refiner, which I am still far from achieving."

However, having reached this stage in weapon crafting, the author has already mastered the identification of spiritual materials and various processing methods in the "Secret Essentials of Weapon Crafting of Tianyue Mountain".

"For shell-type spiritual materials, a cold, yin-type sharp-edged magical tool must be used to peel them off along the 'growth lines' at the joints of the shells, taking care not to damage the 'spiritual glands'..."

"For poisonous spiritual materials, the internal poison must first be sealed using a technique similar to 'Spirit Sealing Technique' before harvesting them. The poison glands and sacs must not be damaged, otherwise the poison will escape and the material will be ruined..."

Using his already "skilled" techniques, He Sheng began to process the centipede's carcass, starting with the lower-value parts.

At first, I was a bit clumsy and made several mistakes.

But before long, the 'mastery' of the knowledge in his mind merged with his body, and He Sheng quickly became proficient.

It took He Sheng a whole day to finish processing the carcass of the centipede. The spiritual materials made from the more than ten-foot-long sharp tentacles and the hooked mandibles containing venom glands alone were worth thirty to forty thousand spirit stones.

Not to mention the various grades of spiritual materials made from other parts.

All things considered, the spiritual materials made from the entire centipede are worth no less than 50,000 spirit stones.

"If it can be refined into a magical artifact, its added value will increase even further!"

He Sheng hesitated for a moment, knowing that the total value of the spiritual materials he currently possessed already exceeded 100,000 spirit stones. If he were to obtain the corpses of the Black Jade Blood Python and the Golden-haired Giant Lion, the number of high-grade spiritual materials he could produce would inevitably increase significantly.

"Using these abundant spiritual materials to forge a batch of high-grade or even top-grade magical artifacts will greatly benefit the improvement of artifact forging skills."

The "Divine Artifact Bottle Forging Method" has extremely high requirements for weapon forging skills. Second-tier low-grade is just the beginning. As one's cultivation progresses, the weapon forging master's rank will naturally need to be higher.

Not to mention that to refine a prototype of a magic weapon, one needs at least a second-tier high-grade weapon refiner, and it is even better to reach the third-tier low-grade level.

"【Art】is inherently time-consuming. The time rate for the first-tier high-grade stage is already 2. It is conceivable that the time rate will be higher as you go higher."

Using universal time for cultivation is simply not feasible.

On the contrary, once a certain stage is reached, using a large amount of spiritual materials to increase proficiency is a cultivation method with a higher time efficiency.

With the leak in his hand, He Sheng knew very well that his cultivation would be completely different from that of ordinary cultivators.

The lower the time efficiency, the less worthwhile it is to cultivate, such as [techniques].

For techniques like "Qinglan Water Control Technique" and "Soul Imprint Technique," directly using the general cultivation time is the most suitable method.

On the contrary, those with high time efficiency, such as advanced immortal arts, are the cultivation methods with the highest time efficiency, as long as they have the necessary resources.

Secondly, there is the breathing and qi refining technique with a time rate of 2.

As He Sheng was pondering his main direction for future cultivation in reality, a voice rang in his ears:

"Immortal Master, you've arrived?"

It was the Green Snake that arrived. Although it had gone ahead of He Sheng, it was two days late because its speed was far slower.

He Sheng snapped out of his daze, looked at the green snake with a beaming smile, and said:

"You've come at the perfect time. Take me to Black Vine Ridge immediately. We must not let any other demon or human get there first to find the bodies of those two great demons."

With that, He Sheng had the green snake lead the way, heading towards Black Vine Ridge.
