System Bestows me with Immortality, Living on to Eventually Become Invincible

Chapter 24 – World Soul, one plant of spiritual herb per month for a hundred years

However, he had heard about mid-grade spirit stones, with the commonly accepted exchange rate being one to a hundred. But in reality, one could easily exchange for 120 low-grade spirit stones.

Chen Xun and Black Bull hid in a secluded corner, their gazes constantly sweeping the surroundings, with one hand gripping the Mountain-axing axe tightly.

"Bull, we're going to be rich," Chen Xun whispered with glee.

"Moo~" Black Bull lowed softly, its head nestled in Chen Xun's embrace, eyes brimming with joy.

The greatest use of low-grade spirit stones was for cultivation, as the pure spiritual energy they contained was far superior to the natural spiritual qi of heaven and earth, which cultivators had to refine to remove impurities.

But that was a practice for the big dogs of the world of immortals; ordinary cultivators could only use them for trade, because the effects of Qi-Enhancing Pills were somewhat better, although they could lead to resistance.

And to develop resistance from consuming Qi-Enhancing Pills meant one was a super big dog; it wasn't something ordinary cultivators even considered.

The next day, they continued peddling their booklets and finally gathered a hundred low-grade spirit stones. Chen Xun trembled with excitement, while Black Bull mooed incessantly, circling around him.

"Bull, we must keep a low profile," Chen Xun said sneakily, feeling as though everyone was after their spirit stones.

"Moo! Moo!" Black Bull understood and called out.@@@@

On the third day, they stopped selling booklets and instead browsed the various stalls. Suddenly, Chen Xun's eyes lit up when he spotted a familiar 'old acquaintance.'

"Miss, it's you."

The girl's appearance hadn't changed much; she was just as he remembered, with several spiritual herbs and bottles of Qi-Enhancing Pills displayed in front of her stall.

She was startled, recognizing those familiar legs and the four black hooves of the bull; the thought crossed her mind—why has this bandit come with a bull again?

"Hehe, it's you," the girl said with a forced smile, the image too deeply ingrained in her memory to forget.

"We're here to buy, we have spirit stones."

"That's great, what would you like to buy?"

The girl's eyes sparkled, her spirits lifted, as long as they weren't here to tease her.

"Could you introduce me to these three spiritual herbs..."

Chen Xun squatted down, offering an awkward smile. Although he had studied medicine, he could still discern a thing or two.

With the girl looking on in amazement, Chen Xun fished out a few spirit stones from his trousers to prove he really had them.

"Alright..."

The girl was taken aback, her gaze dropping to a spiritual herb, "This is Water Cloud Grass, a twenty-year variety, used in the making of Gathering Qi Pills."

"This is Frost Maple Grass, but it's only ten years old, used in Heavy Feather Pills."

"This is Divine Meeting Grass, thirty years old, also used in Heavy Feather Pills."

The girl introduced them one by one. Although not very old, for a solitary cultivator to have harvested so many spiritual herbs was no small feat.

If they were older, many demonic beasts and spiritual beasts would be vying for them.

"Miss, how many spirit stones? I'll take them all."

Chen Xun and Black Bull walked through the valley, their hearts pounding rapidly. They felt their wealth was too great, and countless solitary cultivators might want to rob them.

"Bull."

"Moo~"

The man and the bull exchanged a deep look, quickening their pace and dashing out of the valley, disappearing from sight before the ten great immortal sects even made an appearance.

...

On the outskirts of the Cloud Mountains, they occupied the den of a wild beast, a massive boulder sealing the entrance, immovable by ordinary people.

The boulder was covered in vines, dense and tangled. If one wasn't looking on purpose, they wouldn't even notice there was a cave.

Crack!

A spark of fire lit up, illuminating the entire cave. Chen Xun's face flushed with excitement, while Black Bull ran around wildly.

"Bull, wealth should be concealed, keep a steady mindset."

Chen Xun said with a trembling voice, chuckling, "Look at you, when will you be calm like me?"

"Moo~~"

Black Bull rubbed against Chen Xun, brimming with joy, "Moo moo!"

"We have 15 points of World Soul, that's 30 together, enough to accelerate the growth of spiritual herbs by more than two years in just one day."

Chen Xun grew more excited as he spoke, spittle flying, "Bull, can you do the math? How many years is that in a month?!"

"Moo moo?" Black Bull called out twice, using stones on the ground to do the calculations.

"75 years!"

Chen Xun exclaimed excitedly, looking at Black Bull, "A hundred-year-old spiritual herb every month, my goodness."

"Moo? Moo moo!"

Black Bull was shocked, dropping the stone. They had inquired before—a hundred-year-old spiritual herb was worth between one hundred to two hundred low-grade spirit stones.

They also had spiritual herb seeds; sell those, then buy more, an endless cycle. Who in the world of immortals could have more spirit stones than them?

"Don't get ahead of yourself; we don't have the strength yet to sell in large quantities."

Chen Xun saw Black Bull's expression and knew what he was thinking, "We'll sell one, buy another; that won't attract attention. Besides, we need to refine our own pills."

"Moo moo!"

Black Bull nodded continuously, eyes wide and stunned, nearly floating away.

"Let's first cultivate the three spiritual herbs from the medicine cases to a hundred years. As for those spiritual herb seeds, we'll plant them one by one."

Chen Xun spoke calmly. A hundred-year-old spiritual grass planted outside would attract the attention of many demonic and spiritual beasts with its unique fragrance.

But these medicine cases could not only preserve the medicinal properties but also conceal the fragrance. In the future, they would need to get more, Chen Xun thought to himself.
