Rainbow Cloud Pharmaceutical

Back home, He checked the time. It was nine o'clock, still early.

Within the Immortal Sect, there were several courier services: Cloud Courier, Swift Delivery, Banyan Courier, and others, each with its own pros and cons.

Undoubtedly, the most reliable was Banyan Courier. Its prices were affordable, and its security was high. Even official documents from the Immortal Sect used this service.

Jiang Ding opened the Spirit Group app and selected the 'Harmony Great Pharmacy,' which had the highest star rating. For the refining method, he chose anonymous alchemy—Bone Forging and Qi Replenishing Nourishing Pills for the Inner Qi Realm. For payment, he chose to use some of the medicinal ingredients, and for delivery, he selected Banyan Courier.

With anonymous alchemy, even the merchant wouldn't know the customer's information. However, there was no point in trying any mischief, as the Central Array Spirit Computer could arbitrarily review everything.

Furthermore, the Immortal Sect's industrial development in immortal arts was robust, and competition was fierce. Even mortal-grade pills could be easily refined by alchemists at a low cost, with guaranteed quality.

"Chirp chirp!"

About twenty minutes later, a kingfisher, slightly larger than the previous one, flew to the window. It glanced at the wooden box in Jiang Ding's hand, then produced a thumb-sized plastic bag from somewhere. It blew into the bag until it was the size of a computer screen and nudged it with its beak.

Jiang Ding understood. He opened the wooden box, letting it get a clear view of its contents, and then rummaged through the various compartments—

This was a security check. The kingfisher had security spells on it, and the process would be uploaded to the Central Array Spirit Computer to serve as evidence in case of future disputes.

"Chirp chirp!"

The kingfisher flapped its wings, signaling him to place the wooden box into the plastic bag. Then, it hooked the plastic bag with its claws and flew away.

Jiang Ding felt at ease.

Very few people could rob or steal from Banyan Courier. Even if it were stolen or robbed, compensation would be provided later.

According to the customer service of Harmony Great Pharmacy, the pills would be refined and delivered within three days.

"What's this?"

Just as Jiang Ding was about to close his phone to practice swordplay, he noticed an unread message on the library icon.

'Shao Chengkang, a Level 1 Researcher at Rainbow Cloud Pharmaceutical Group, has viewed the information of the plant specimen 'Purple Spirit Grass' you submitted and wishes to communicate with you.'

Rainbow Cloud Pharmaceutical!

Jiang Ding's heart leaped with joy.

This was a major company from the neighboring Caiyun Province, well-known throughout the entire Immortal Sect. The White Cloud Marrow Nourishing Pill, one of the Foundation Establishment spirit medicines, was invented and popularized by this company, which held patents for all previous versions of the pill.

'Purple Spirit Grass' was a new plant discovered by Jiang Ding. It came with a patent duration three times its natural lifespan upon discovery. For mortals, this was typically 100 years, meaning he had a 300-year patent.

This was considerable.

For mortals, it was fine, but for Golden Core or Nascent Soul cultivators, patent periods were usually over a thousand years, enough for several generations.

Therefore, both families and companies were extremely fervent about various patented inventions.

During this period, any person or organization using Purple Spirit Grass or its unique active ingredients must pay Jiang Ding the corresponding patent fee.

There was a precedent for the fees: for mortal-grade medicinal ingredients, 0.1 Mortal Coin would be charged per item, or 0.001 Spirit Coin, depending on whether the product using the patent was a spiritual item or a mortal one.

"It's not easy. I've uploaded nearly 500 new plants, and finally, one is useful," Jiang Ding sighed.

He clicked to agree to communicate—anonymously.

Soon, the other party replied. Large companies like this always had staff on duty 24 hours a day.

"Hello, sir. I am Guan Xin, a Level 1 Researcher at Rainbow Cloud Pharmaceutical. Our company requires some live Purple Spirit Grass. Would you be able to provide it? Our company will pay the corresponding fee."

Jiang Ding was slightly disappointed. He had thought they were coming to discuss patent licensing.

Such large companies often bought out the patent rights for a product. Although they would lose out in the long run, they could obtain a large sum of money in a short period.

"Yes. How much can you offer?"

This was not something to hesitate about.

If it were elsewhere, Jiang Ding wouldn't dare to agree. Once he sent it over, they would definitely exploit it for free and never return it. But in the Immortal Sect, there was no need to worry about such things.

"30 plants, 3000 Yuan. How about that?"

"Okay. It will be delivered within 7 days. Please leave an address."

Jiang Ding dared not haggle. At this stage, they were clearly in the research phase and hadn't confirmed if they would use the Purple Spirit Grass. He didn't want to create obstacles from the outset.

The last class of the afternoon was mathematics.

"Class, the Sharp Gold Formation is one of the five basic formations. It can condense metal attribute energy and increase sharpness. The principle is actually very simple, much like how we add a metal blade to a wooden handle. The key is to condense metal attribute spiritual energy using the formation..."

"It is often used in weapons through micro-engraving techniques..."

The last class of the afternoon was mathematics, taught by Ms. Wang Lan, a stern middle-aged woman.

In the classroom, Jiang Ding listened half-heartedly, feeling his head was about to explode. Suddenly, he paused and flipped through several pages of his book.

'Why does this look so familiar? Divine Firmament Hundred Pace Flying Sword!?'

He suddenly realized that the Sharp Gold Formation and the Hundred Pace Flying Sword cultivation technique had some surprisingly similar key points. When combined, the mathematical problems that were originally difficult to understand and relied solely on rote memorization suddenly made sense.

"Now, let's begin the practical session. Please sketch the Sharp Gold Formation on the talisman paper."

Upon hearing this, Jiang Ding and the others carefully opened their spirit ink, picked up their talisman brushes, and spread out their talisman paper—these were all spiritual materials. They were only given three sheets of talisman paper, and the spirit ink and talisman brush could only be used during class.

Even though the Immortal Sect and immortal path industries are highly developed, requiring only a small amount of spirit materials to create what is needed, the total number of high school students across all regions adds up to a massive daily quantity.

Jiang Ding glanced to the side. Li Junhao's face was solemn. He had specifically brought a magnifying glass and started by practicing with ordinary white paper and ink. In no time, he had drawn dense diagrams of the Sharp Gold Formation.

Don't underestimate this mere mortal in the Flesh Refining Realm; if energy were input, this formation diagram could genuinely emit a golden light and then self-destruct.

Jiang Ding was convinced of this point.

Including himself, most people, many Martial Artists in the Inner Qi Realm, and some cultivators in Qi Refining, drew formation diagrams that appeared complete but were actually just for show and completely unusable.

Out of ten questions, getting two points was already due to the teacher's leniency.

Jiang Ding initially wanted to learn from Li Junhao and practice with white paper first. The more he watched, the more his hands itched. Fortunately, he picked up his brush and started drawing, beginning from the central formation base and extending outwards in the pattern of the Eight Trigrams.

Countless insights emerged from his heart: scenes of him practicing swordplay over the years, the time he charged alone towards a group of mountain bandits and scattered them, the core cultivation technique of the first level of Talisman Sword from Divine Firmament Hundred Pace Flying Sword...

He drew faster and faster, meticulously etching dense, hair-thin formation patterns onto the paper. Only one last stroke was needed to complete the entire formation diagram.

This final stroke involved the soul and breath. He had never learned it and couldn't even imitate it.

His hand holding the Talisman Brush stiffened and trembled for a long time before he finally couldn't bring himself to make the stroke.

"Draw the hook stroke, dry stroke."

Wang Lan's voice suddenly rang out, carrying an unfathomable power. Jiang Ding involuntarily followed her instructions and heavily placed the final stroke.

Suddenly, the ordinary-looking Talisman Paper in front of him generated a powerful attraction. Something in his mind seemed to surge out and pour into it.

"Pain..."

Jiang Ding's face turned pale. His head felt like it was splitting apart, an unbearable, searing pain, as if an iron nail was being driven into his mind. It took a long time before he recovered.

He looked closely. The Talisman Paper before him seemed to have a faint layer of light and a weak connection with him.

"Where did you see this formation diagram?"

Teacher Wang Lan's face was filled with anger. "How many times have I told you not to look at things beyond the syllabus? Don't look! If I hadn't been watching today, do you know you could have suffered brain death?"

Jiang Ding stood up, lowering his head. "Teacher, I was wrong."

But inwardly, he didn't regret it much. With his poor aptitude and ordinary family background, if he wanted to embark on the path of immortality, he had to be aggressive where necessary.

Wang Lan seemed to sense something, her anger intensifying. She flicked her sleeve.

"I will inform your guardian truthfully."
