The red wall of the Seven Star Chamber of commerce still looks very solemn, but in Fang Cheng''s eyes, the red is probably dyed by the blood of many people.

    "I''ll ask you to take care of it."

    It''s not the first time Fang Cheng has been in and out of the Seven Star Chamber of Commerce. He''s already familiar with the road. Hearing Fang Cheng''s instructions, a young boy immediately bowed and ran away.

    a moment.

    A middle-aged man in a gray embroidered robe came slowly. Although Fang Cheng didn''t see the man for the first time, he had never dealt with him.

    "Sir." The steward gave Fang Cheng a salute, "I''m the senior steward of the Seven Star Chamber of Commerce. You can call me John."

    "Fang Cheng." Fang Cheng returned a gift and said.

    "What do you want to buy in our chamber of Commerce? Or what goods do you want to sell?" John had doubts in his eyes. He looked familiar to Fang Cheng, but he couldn''t remember where he had seen him for a moment.

    "I want to buy some magic blood from your Chamber of Commerce. Do you have any stock?" Fang Cheng''s tone was flat and he couldn''t hear joy and anger.

    Sure enough, after hearing this, John''s face changed from relaxed to dignified.

    "Lord Fang Cheng, our chamber of commerce does have magical blood, but the price..." John paused. "The price is not cheap."

    "How many gold coins do you need?" Fang Cheng was not surprised. He was not the first newcomer to the foreign world. He knew the price of these materials long before he came to the Seven Star Chamber of Commerce.

    "Ten thousand gold coins a barrel." John steward stretched out a finger and said slowly.

    Sure enough, Fang Cheng heard this and sighed in his heart that the magic blood was too cheap.

    Yes, it''s cheap. To know the price of Merlot, it was just a small test tube. When Fang Cheng bought it, he spent 3000 gold coins. Now a bucket of magic blood only needs 10000 gold coins.

    How much is a bucket of magic blood?

    When Fang Cheng saw that John ordered someone to send it to him, Fang Cheng took a light breath.

    The sealed wooden barrel in front of me, although I don''t know what wood it was made of, exudes a fragrance. Outside the barrel, a layer of wrapping pulp was brushed to preserve the magic blood for a longer time.

    If this barrel is full, it can hold 5L of magic blood. How much Merlot is in a test tube? 50ml at most. In this way, if all the magic blood in this barrel is made into Merlot potion, it can make almost 100. If converted into gold coins, 300000 gold coins.

    Of course, this is an ideal state. In fact, if an ordinary wizard apprentice configures Merlot potion for the first time, one hundred can succeed, even if he burns high incense.

    The configuration of Merlot medicament does not need any special methods, but just grasp the proportion and the time of solution mixing, but it obviously needs to pay a huge price for a novice.

    These are nothing. The most important thing is that there is no formula.

    The cost of developing a pharmaceutical formula is almost unimaginable to ordinary people. Therefore, the resources and wealth that can be obtained after having a formula are naturally unimaginable to ordinary people.

    In fact, this is very similar to the intellectual property rights of the earth, but the world monopolizes intellectual property rights more thoroughly. No wizard will divulge the pharmaceutical formula he has tried hard and at a great cost.

    The formula is the key to a pharmacist''s wealth and their most precious wealth. Fang Cheng is almost certain that Viscount Morton has the formula of Merlot.

    Even, it is likely that he himself is a pharmacist.

    With the payment of 10000 gold coins to John steward, Fang Cheng got the magic blood as he wished.

    The next step is to prepare Merlot.

    ......

    In the castle of Fangcheng manor.

    Fang Cheng sent off the servants, locked himself in the room, and then took out the four materials equipped with Merlot medicine.

    "Enter data."

    Fang Cheng ordered the intelligent learning machine in his mind.

    With Fang Cheng''s instruction, the four materials were entered by the intelligent learning machine. Fang Cheng checked the database, looked at the detailed introduction of the four materials and nodded.

    Then, the next step is to learn how to configure Merlot in the virtual learning space. Fang Cheng thought.

    In the virtual learning space.

    At this time, the virtual learning space has completely changed its initial appearance. If an ordinary earth person comes, he will find that it has become a modern chemistry laboratory, in which all kinds of glassware for chemical experiments and all kinds of equipment for processing materials are displayed.

    The first step is to completely extract the juice of ghost noodle flower.

    Ghost face flower, as its name suggests, is a rather ugly flower. The petals are black as a whole. There are six petals in total. Therefore, ghost face flower is also called six ghost face flower, which is famous for its ugly appearance.

    But what ordinary people don''t think of is that it is an essential material for the preparation of Merlot.

    Fang Cheng carefully followed the steps suggested by the data step by step, but ten times, all the extracted ghost noodle juice were unqualified, either the concentration was low or there were many impurities.

    This is Fang Cheng''s achievement in the virtual learning space. If it is in reality, Fang Cheng doesn''t know whether he can succeed once a hundred times.

    However, this is only the first step of configuration. There are still three kinds of materials to be processed. Finally, they have to be mixed. No mistakes can be made in each step. Otherwise, the consequences will be lighter, the negative energy index will exceed the standard, and the serious point will be the end of drug scrapping.

    Fang Cheng wiped the sweat on his forehead.

    Again!

    Time passed minute by minute in Fang Cheng''s continuous experiment.

    After three hours, Fang Cheng was exhausted and fell into a gorgeous coma.

    The next morning, Fang Cheng woke up and ordered his servants not to disturb him. He continued to study. He had gone to the third step in three hours yesterday.

    However, if the fusion of purified liquid fails every time, Fang Cheng will pack up his mood and configure purified liquid again.

    Fang Cheng looked at the processed material solution lying quietly in three test tubes and took a deep breath. The right hand becomes extremely stable in the process of dispensing medicine countless times.

    Fang Cheng doesn''t know how difficult it is to configure medicine as an ordinary person. It completely needs to be operated by hand. Unlike those wizards, they have the ability to release spiritual power and can accurately operate each step.

    But even so, if the success rate of witches in dispensing potions can be one tenth, it will be regarded as burning high incense.

    It can be seen how difficult it is to configure medicament, let alone to study medicament formula, which costs a lot of resources and time.

    Until the third day.

    In the virtual learning space, Fang Cheng almost wanted to cry after picking up a test tube with a ruby like liquid flowing inside.

    Mello medicament with negative energy index of 0 was finally configured successfully. This medicament has another name among pharmacists, which is called perfect medicament.
