Chapter 77 Bordeaux Liquid

  Back in his own room, Hua Yun carefully checked the instruments given to him by Xi Na. He had to say that Xi Na was a very efficient and reassuring person. The instruments in the box, which were made by Xi Na's skilled craftsmen and alchemists, were quite to Hua Yun's taste.

  For example, this mirror tube inlaid with a polished convex lens made of optical crystal, after being added with Eagle Eye and Clarity by the alchemist, and equipped with a specially made base, has an effect that is no worse than an optical microscope in an ordinary laboratory on Earth.

  However, this kind of microscope made with magic from another world, alchemy and forging techniques can generally only observe relatively larger microorganisms such as nematodes, cells, fungi and bacteria. It is still far from enough to use it to observe viruses, after all, due to the limitations of technology, it is impossible to make a microscope with magical means that has functions as powerful as an electron microscope.

  Apart from the microscope, the box was filled with instruments similar to culture dishes, test tubes, distillation flasks and burettes, as well as some miscellaneous experimental equipment. Anyway, Huayun thought that he could make them, so he drew detailed diagrams for Xina, who wasn't afraid of Xina using these diagrams to create more instruments. Apart from himself, Huayun didn't think anyone else in this world would use these instruments that shouldn't have existed in the first place.

  After setting aside the instruments and materials she would need immediately, Huayun put all the remaining instruments into the Qiankun Ring.

  The fungal spores that caused the rust disease in those two sacred plants were quite easy to get rid of, but if Hua Yun only treated them, they would probably be infected again within a few days. To prevent the recurrence of the rust disease, Hua Yun began his first attempt at formulating chemical pesticides in this world. The solution he formulated was Bordeaux mixture, a non-toxic pesticide that has been widely used for countless years all over the world.

  Anyone who has studied junior high school chemistry knows that Bordeaux liquid is a plant protective bactericide prepared from lime water and copper sulfate, which has an excellent killing and preventive effect on the fungi of plant rust disease.

  As limestone also exists in Ailen continent, so the preparation of lime water is relatively easy. The difficulty lies in the preparation of copper sulfate solution.

  To obtain copper sulfate, sulfuric acid is required, so Huayun uses the method of preparing industrial sulfuric acid. Xina purchased a batch of yellow fire stones that only exist in the Fire Flame Cave, which are sulfur, and let Xina use the fire spirit crystal stone to build a closed distillation container. By letting the sulfur oxidize, it is possible to obtain oxidized sulfur, and finally get sulfuric acid. Then add copper oxide to the sulfuric acid, filter and neutralize it, and you can get pure copper sulfate solution.

  This process is quite important, especially for the combustion of sulfur to produce oxidized sulfur. The control of fire is very delicate. Huayun directly called Talya over and let this powerful fire mage control the fire, which wouldn't be worse than using instruments on Earth.

  At the time in the castle, Talya had already seen Huayun's strange treatment methods. Without a word, Huayun told him to do something and he did it one by one. In the battle against the Storm Bandits, Talya saw that as a Plant Master, Huayun was also an extremely powerful warrior, and his heart was filled with respect for Huayun. Dual professionals are not easy to come by; they often have to pay several times more effort than ordinary people to achieve the same accomplishments as ordinary people.

  With Tally's help, it didn't take long for Huayun to prepare a small bottle of Bordeaux liquid. Afterwards, she put everything away. Unlike ordinary solutions that won't go bad as long as they're sealed and stored properly, the Bordeaux liquid will lose its effectiveness after being left out for a period of time due to chemical reactions within it. Preparing too much would be wasteful.

  The next day at noon, in Xina's room, Huayun was applying Bordeaux liquid to the two holy stepmother plants in front of Xina.

  "Is... is that it?" Looking at Hua Yun standing beside him saying treatment was already complete, Xi Na couldn't help but be stunned.

  "Alright, take a look, your two Holy Tier Divine Gifted Plants have gradually recovered over these days. What's wrong, Lord of Sina City? Don't tell me you're thinking of welching on the deal?"

  Actually, Hua Yun had already cleared the rust fungus from those two divine gift seedlings two days ago. He stayed here for two reasons: one was to let Xina see the effect after a period of time, as he didn't have the Time Flowing Scroll; and the other was to prepare Bordeaux liquid to prevent these two divine gift seedlings from getting infected again in the future. Otherwise, it would be useless within a few days, and these two divine gift seedlings would likely fall ill again.

  "This... of course isn't..." Xina waved his hands repeatedly, looking at the two divine plants in front of him that had gradually regained their vitality and whose spots on the leaves were also disappearing. He was utterly shocked by the treatment method Huayun had used.

  As the Marquis of Xina and head of the Noki family, he had a unique perspective. He had heard that Master Hua Yun's method for treating demonic curses was unconventional, but he hadn't expected it to be this unusual. The master had bought various materials with unknown purposes and crafted strange instruments before applying some sort of blue substance to the sacred plant, all without using any Plant Magic during the entire treatment process.

  No, I've used several Life Blessings and Revivals on this... Can a first or second-tier Plant Master's magic heal a Sacred Tier Divine Gifted plant? Something like that, Xina has never seen before, nor even heard of.

  For a moment, Hua Yun became mysterious in Xi Na's heart!

  It's not surprising that Xina would think this way. Let's just imagine a scenario: in reality, a billionaire buys a pot of his favorite plant, but unfortunately it gets sick. He finds countless botanists who can't cure it, and then he invites a very famous botanist who is actually a divine plant master from the Allen continent. When the divine plant master sees the plant, he immediately understands that it has been cursed by an evil spirit. Just as the billionaire asks him what medicine to use to treat it, the divine plant master casts a 10th-level plant magic spell without saying a word, and the plant instantly recovers, completely restoring its original vitality! What do you think the billionaire would think? It's like having a god, even if it's not that exaggerated, there must be some mystery and reverence!

  Xina is now in such a situation, he has been completely shocked by Huayun's approach.

  Now that the rescue is complete, Xina's previous promise should also be fulfilled. In Xina's painful eyes, Huayun cut off a lush branch from those two divine plants.

  "Hua Yun Master, this is the Sacred Tier Divine Fruit you wanted!" Xi Na winced in pain as she took out a box made of purple crystal from her body, but her expression was extremely natural, and her tone when speaking to Hua Yun became even more respectful than before.

  Before, Xi Na was condescending to Hua Yun with a tone of reluctance, but now that she has seen Hua Yun successfully treat her family's sacred Saintly Bestowed Plant, that reluctance has completely turned into genuine respect and gratitude.

  A Plant Master who can treat the Divine Gifted Plants of the Sacred Ranks, there might not be even a few on the entire continent of Allen. Such a person would be pulled and connected by countless people wherever they go.

  Looking at the purple crystal box where the holy fruit of the sacred stage was placed with a radiant glow, Hua Yun smiled slightly and took over the purple crystal box, casually putting it on her body.

  "Host of Xina City, I have stayed here for quite some time now. We will set off tomorrow, is there anything else? If not, I'll take my leave first."

  "It's like this, Master Hua Yun, I just so happen to have something else!" Xina called out to stop Hua Yun from turning around and leaving. He also understood that someone like Hua Yun wouldn't come out of the royal city for no reason, there must be some urgent matter that required his personal attention. At the same time as he felt even more grateful towards Hua Yun in his heart, a thread of guilt actually arose.

  After a moment's consideration, Xi Na said: "I heard that Master Hua Yun has a batch of divine plants and power seeds. I wonder if they can be sold to me?"

  "Divine saplings and power seeds?" Hua Yun couldn't help but feel amused in her heart, weren't these things the ones she had snatched from Kalan? This Xina was no good at asking me to return them, so she could only buy them.

  "Yes, I am willing to pay 5 million gold coins for these divine plants and power seeds. I wonder what Master Hua Yun thinks?" Xina looked at Hua with a face full of expectation.

  Actually, these divine sprouts and power seeds are worth at most over 30 million gold coins. However, because Hua Yun cured the two divine sprouts that had been passed down in her own family for generations, Xi Na was extremely grateful to her. If he hadn't had a delivery deadline with someone else approaching soon and couldn't find another batch elsewhere, he wouldn't have made such an embarrassing purchase from Hua Yun. For the Nuoqi business clan, which has existed for hundreds of years, this small amount of goods is not worth much despite its high value.

  "If Xina City Master wants it, then there's no problem!" Even if Xina doesn't buy it, Huayun would still find someone to sell it to in Nuoqi City, but carrying several carts of goods is not convenient for them.

  "Then thank you, Master Hua Yun!" Xina let out a long sigh in her heart and continued: "I'll send someone to pick up the goods later, and I'd like to ask Master Hua Yun to go with me to settle the account later."

  "Hehe, great!" Hua Yun didn't think that snatching things would be so profitable. The special divine fruit that he had painstakingly created to directly upgrade people was only sold for 3 million, but now with Xina's 5 million and Karan's additional 1 million, he suddenly gained an extra 6 million.

  At this moment, Hua Yun's heart is thinking that in the future, he should grab more, this is simply a huge profit!
