The support mission to Snake Island wasn't going well, which had Zhou Yi furrowing his brows with worry.

Da Vinci needed a strong anesthetic for surgery, but purchasing such controlled substances required a licensed doctor to go through face-to-face validation and registration, with no allowance for proxies or delegated collections.

It was only thanks to the Wasteland Development Company's latest upgraded B-level credit rating that they managed to get a small amount of ordinary anesthesia from Chuneng City.

Cities like Little Smoke Ridge, within the New Human City, were too laxly regulated, allowing banned smoke pills to circulate openly within the city.

Mechanical City, on the other hand, had swung to another extreme, emphasizing strict procedural adherence.

For this reason, Red Kestrel had no choice but to travel to the more distant Recursive City to continue their procurement attempts.

It said, "Details like medicine storage and sales quantities are not shared between cities. So in other Mechanical Cities, we could still buy some anesthetics according to the quota."

Unexpectedly, two sea lords next to Recursive City went to war in winter, turning the surrounding area into a battlefield and forcing Red Kestrel to take a long detour further delaying their progress.

Misfortune never comes singly.

After finally arriving at Recursive City, it turned out that there was a severe drug shortage there; they weren't selling to outsiders and only supplied to doctors within the city.

It was all because of this winter war.

The two combatant sea lords had stockpiled large quantities of related medicines early on, using them as logistical resources for the battlefield.

This served as a reminder to Zhou Yi.

Winter indeed was a turbulent season, with the Snake Island incident before and sea lord conflicts afterward.

Jade City, however, was unusually calm, representing a special exception.

The only good news was that the Monster Attraction Mushroom was proving to be highly effective, essentially filling the gap left by the lack of anesthetics.

Feedback from Da Vinci was positive.

Zhou Yi thought to himself that it was essential to own relevant industries. Otherwise, when the critical time came, there would be nothing available to buy.

Three days later, Da Vinci was air-shipped back to Jade City by Lie Hai.

Because Breaker Haruk had previously hunted crazily everywhere, the nearby Dead Sea became peaceful and turned into a real safe zone, making the round trip much smoother.

After returning, Da Vinci first reported the basic situation to Zhou Yi, then headed straight for the Mushroom Forest. It summoned the discoverer of the mushroom, Cao Dayuan, and the person in charge of the Mushroom Forest, Sun Chonglai; the three of them began to study the Monster Attraction Mushroom together.

Concerning the mushroom with anesthetic properties, the Mechanical Doctor's assessment was, "Unique; no similar drugs have appeared before."

However, the Snake Island incident as described by Da Vinci took Zhou Yi by surprise.

Having experienced multiple Light Bursts personally, he knew such disasters in the Dead Sea indeed caused undiscriminating decay of life. But as long as one kept away from the affected area in time, radiation damage would be reduced.

Light Burst itself could only last a very short period, similar to a flashbang, with its initial power indeed strong but then quickly dissipating.

"Under normal circumstances, most Light Bursts indeed last a very short time."

Red Kestrel said, "But this time, the Light Burst reached B-level strength, and since Snake Island was too close to the site of the incident, it resulted in a large number of Sheng Snakes getting injured."

If not for Da Vinci tirelessly performing timely surgeries, and the small hospital building having some containment defense capabilities, the casualties on Snake Island would have been much worse.

While Zhou Yi and the Red Kestrel were discussing, Da Vinci contacted Red Kestrel from afar, reporting a new discovery.

"After experiments and comparisons, we have identified the growth mechanism of the Monster Attraction Mushroom."

"Initially, its mycelium grows outward, forming the stem and cap, but during the maturation stage, the mycelium starts to grow downwards, causing the cap to shrink rapidly. However, downward growth requires more energy and nutrients, so it grows extremely slowly, and they almost always die of malnutrition, though this is not obvious."

"Simply regularly trimming the mycelium at the bottom and artificially altering the growth cycle of the Monster Attraction Mushroom can allow them to grow larger. This is one of the simplest methods."

"I tried conventional methods like steam treatment, extraction, and soaking, but found that the best results come from moderate to low-temperature dehydration. We've had Ye Zhao, Cao Dayuan, and many sand rats test it, and the difference between the dehydrated dried mushroom and the fresh Monster Attraction Mushroom is already very small."

Zhou Yi's heart lifted with joy.

After all, Da Vinci was a doctor and also had a decent understanding of pharmaceuticals.

"There is another important matter I'd like to consult with you."

Under Red Kestrel's camera lens, waveforms were speeding across Da Vinci's screen.

"Chairman, I've checked the latest medical encyclopedia, and the Monster Attraction Mushroom is an entirely new natural drug that has not yet been indexed. I suggest we register the discovery rights soon and complete drug registration, as this will bring long-term continuous economic benefits. At least within Mechanical City, whether it's cultivation or sale, the company will earn a certain percentage of profits, and the entire revenue period could last 70 years."

"If the company conducts independent trials and develops new drugs, it will require at least ten years of clinical trials before there's a chance to obtain drug approval, involving a large amount of equipment and professional participation... A patent-sharing model could scale up Monster Attraction Mushrooms more quickly, and also promote the derivation of a variety of new drugs, bringing greater profits to the company."

Zhou Yi's eyes gleamed.

Revenue sharing? That sounded quite interesting.

He asked Da Vinci to elaborate.

Mechanical Doctor said, "The relevant standard procedure was initially initiated and established by Holy Mountain. It is based on sharing fundamental information in the medical field, with the Medical Encyclopedia as the core, allowing medical technology to rapidly develop through each Mechanical City."

"Medicines, diseases, doctors, and treatment cases from all places will continuously supplement the Medical Encyclopedia. Doctors with professional qualifications can access it, and a large number of practitioners will continually expand the knowledge base of the medical field."

"To enhance motivation and the spirit of sharing, Holy Mountain has created the Holy Healing Fund, which rewards and thanks doctors who discover new drugs and treatments. After more than a hundred years of operation, it is now very mature."

"Discovering new drugs and sharing information gives one discovery rights and a 70-year patent right."

Zhou Yi asked, "Is Holy Mountain a city or an institution?"

"Holy Mountain is one of the Five Great Centers and one of the most developed areas on land. It is a city cluster, located 8000 kilometers northwest of Jade City."

"What are the Five Great Centers?"

Da Vinci said, "The Five Great Centers include 'Snow County,' 'Mirror City,' 'Flower Town,' 'Winged City,' and 'Holy Mountain.'"

"Snow County is located in a cold area, has vast land and a large number of monks. They meditate and generate the Wisdom Cloud. People can gain wisdom by entering the cloud and share their opinions and discoveries."

"Mirror City controls the technology to collect and utilize Death Light, with many alchemists and craftsmen. It produces various new devices and tools and is an indicator in the field of Death Light Technology."

"Flower Town has developed flowers of all shapes and colors, which can be tools, weapons, or even companions."

"Winged City is home to many Flying System Guangna Species, has strong air control rights, and air trade is very developed."

"Last is Holy Mountain, which has a rich variety of species and abundant water sources. It is a holy land for medicine and cultivation, with numerous doctors and farmers."

Zhou Yi memorized these names.

Next, Da Vinci explained the registration process. It was really about registering the relevant drug information, then it would go through on-site inspection and audit.

"Chairman, should we change the name of the Monster Attraction Mushroom?"

Da Vinci expressed, "Its function is not limited to acting as bait in the wild but allows patients to temporarily break free from physical pain and bodily constraints, achieving a pure state of self-consciousness, to gain valuable serenity. It has significant uses for surgical treatment of external injuries as well as in addressing psychological trauma."

Zhou Yi thought about it; it could bring about sage time and was a medicine that could help various flesh and blood beings temporarily forget their pain.

"Then we'll call it Wise Mushroom."

"Good, it's a very good name."

There was a ripple on Da Vinci's screen.

"Registration is complete, now we just wait for the audit."

To Zhou Yi's surprise, the auditor visited just one hour later.

The visitor was a genuine grey and white fixed-wing aircraft, capable of accommodating at least a dozen people, flanked by two smaller aircraft escorting it.

"I am the Chuneng City Run 9 Medical Rescue Aircraft 'Cloud Track,' and an auditor from Holy Mountain. I'm here to confirm the specifics of the new drug 'B40099.'"

"Please provide the site for conducting the new drug experiments and testing procedures."

Guided by ground control, the medical rescue aircraft slowly landed.

Da Vinci began working with Cao Dayuan to assist the auditor.

The auditing process lasted for 74 hours and included sample collection and ingredient testing, clinical trials and observations with volunteers, and various procedures such as comparative analysis.

Zhou Yi was getting a bit impatient.

Finally, Cloud Track affirmed, "After the complete process of auditing, this drug meets the relevant basic standards and is confirmed as a new natural medicine. It has strong sedative and anesthetic effects and also has a strong stabilizing effect on the psyche. Current side effects are unknown."

"After audit by Holy Mountain, Wise Mushroom is rated as B-grade. Discovered by Wasteland Development Company, according to the rating standard, the profit-sharing ratio for the 70-year patent right is 5%."

"Any Mechanical City that participates in cultivating or profiting from the raw materials of this drug will pay 5% of net profits into the Holy Healing Fund's specific transfer payment account."

"This account is under the discoverer's autonomous and free control, settling every 30 days and lasting a total of 25,550 days. The account is connected with Holy Mountain, Snow County, Mirror City, and 138 other cities. It can be accessed via an identification code..."

"Congratulations on your discovery and sharing, and we sincerely thank you for your precious contribution to the world of medicine."

"The name of Wasteland Development Company will forever remain on Holy Mountain and become a part of medical history."

"With that, I have finished and will take my leave."

After completing the notification, Cloud Track took off again to head towards another destination.

Da Vinci, uncharacteristically, showed pleasure and excitement: "Chairman, Wise Mushroom will help thousands of patients! This is a remarkable discovery and achievement!"

What Zhou Yi was concerned about was how much they would actually share each month.

But, in any case, this profit model was far more convenient than selling Wise Mushroom everywhere.
