Knott got what he wanted, and Mellen Watts left satisfied. Tang Bai also received a repeated promise from Noether that he would help him verify the experimental effect of Norwegian dragon blood in detail, and help him concoct dragon blood doped with potions when the time came.

Even after getting his hands on the Norwegian dragon's blood, Nott said very happily that when the time came, he could send Tang Bai the recipe of the potion that could forcibly and quickly induce the effect of the dragon's blood, along with the configured potion.

This kind of ancient potion recipe, which had to disappear into people's lives because of the loss of an irreplaceable main drug, is not uncommon in the history of potions. Many potions that were famous three or two centuries ago, and if you want to know more about their information and use, you can only go to the magic library and look through the ancient books that are dedicated to them.

Due to the lack of the main potion and whether or not a replacement was found, no matter how brilliant the fame and wide range of uses of these potions had to be disgraced from the stage of potions. No matter how good the recipe is, without the support of the material, it is just an ordinary piece of text and paper with some commemorative meaning at best.

Therefore, when a unique and precious potion comes to an end, or is eliminated for other reasons, whether it is a certain potions master, or other wizarding families including pure-bloods or half-bloods, most of them will be generous and unreservedly disclose their unique potion recipes to the public for free, and squeeze out the last bit of potion to exchange for some prestige for themselves.

Of course, even in the Hogwarts Magical Library, which has the most extensive and sound documentation, it will take a lot of effort and time to find out the answers. Maybe in the end, you may end up with nothing. Nott's move saved Tang Bai a lot of trouble.

Of course, some potions with special effects, which are feared and feared by many wizards, are mostly impossible to conceal or restricted under the laws of the wizarding world today. For example, truth tellers? Compound decoction and other medicines.

For example, in the face of the law, the elixir cannot be easily used on wizards, unless you have some special duties or have the connections and prestige of Dumbledore.

But that doesn't mean they can't be profitable. The potions master who invented this potion had an innate advantage in the selection and hoarding of potion materials, as well as in cultivation. As a deal to announce the potion formula, the Ministry of Magic naturally has to give some corresponding benefits and support.

Either it is the exclusive right to sell a certain type of main drug in the potion for a certain period of time, or the right to plant, or it is to give a certain amount of time to occupy the market.

Many of these materials and items that are closely related to the life of wizards are in the hands of people like Mellen Watts, and of course, the pure-blood wizard family has much more resources than people like Mellen Watts. Therefore, most of these pure-blood wizard families have a lot of prestige and power in the wizarding world.

To paraphrase a phrase, pure-blood wizard families are the truly privileged class of wizarding worlds, and they have enough resources in their hands to make those in the Ministry of Magic who are dissatisfied with them feel jealous, and then they have to remain acquiesced and tolerant of certain things about them, and dare not force them too much.

When the potion prepared with the clover of life and death grass as the main material came out of the finished product, unless Tang Bai did not want to sell it, the formula would inevitably need to be announced. Just like Nicolamay, although he made the Philosopher's Stone, he also caused a lot of trouble for himself because of the Philosopher's Stone, so he had to reveal the role and power of the Philosopher's Stone, and lived in low-key seclusion.

Once anything is related to life, whether it is a Muggle or a wizard, most of them will be impatient by the ** in their hearts.

According to the information provided by Mellen-Watts, the Clover of Life and Death does have the ability to prolong people's lives, except for being able to resurrect people who have just died and whose bodies have not yet begun to decompose. This has been proven in certain humanoid magical creatures, as well as with certain Muggles and a very small number of wizards.

Of course, all of these subjects were eventually completely washed away from their memories of the experiment by the Oblivion Curse.

The only thing that restricts Tang Bai and Mellen-Watts now is the cultivation and cultivation of clover grass and life. Because of the special surname of the nutrients required by the clover of life and death, it is determined that it is temporarily impossible to supply a large number of potions for testing and consumption.

Unless it is the spring water of the Fountain of Youth, it can really replace the effect of the fire dragon's blood and take effect on the three-leaf grass of life and death. At that time, the potential of the clover grass may be able to be tapped to the maximum.

Tang Bai didn't have to worry about the safety of the clover and the theft of the grass at that time. The Fountain of Youth, in this world, is the only one who can obtain a large amount. Even if others get the clover of life and death grass and want to plant it in large quantities, even some extremely wealthy pure-blood wizard families will probably have to make a disgrace and lose everything. Wanting to compete with Tang Bai and them is tantamount to a fool's dream.

The waiting time passed day by day, and Tang Bai would see Mellen Watts every day. Although Tang Bai handed over the management of all the businesses here to Mellen Watts, when he was there, Mellen Watts would report to him every day about his estate. This has almost become the norm.

At noon on the eighth day of Tang Bai's arrival, after Tang Bai had lunch with Mellen Watts, he received a message from Bogin Bock with an owl. After reading the letterhead that the owl put down, Tang Bai felt slightly depressed and couldn't help but breathe a sigh of relief.

Before the news came from Noether's side, Borgin Burke's side rushed to deliver good news.

"Borgin Bock's letters?" Mellen Watts just glanced at the open letterhead in Tang Bai's hand and guessed who the owner of the letter was. In fact, it's not hard to guess. Although Tang Bai had met many people under the introduction of him and Nott in the past, there were not many people who had deep friendships.

Able to obtain the address of Don Bai's residence and accurately send the letterhead with an owl, apart from him and Notte, it seems that there is only one Borgin Bock here. Mellen-Watts knew that it would take some time for Noether's experiments to bear fruit.

"Yes, I need to visit him in the afternoon. Would you like to go with me? Tang Bai raised the letter paper in his hand and said with a smile.

"No, no, no, I'm not as idle as you. I have a lot of work to do in the afternoon. Mellen Watts waved his hand busily and refused.
