Seeing Fang Cheng''s serious expression, the wizard apprentice who set up the stall immediately showed a bright smile on his face.


    He clenched his right hand, stroked his chest, and made a line of noble etiquette towards Fang.


    "This wizard, what do you call him?" The apprentice in front of him was dressed in gray robes. He didn''t look like the standard clothes of any large power. He should be the child of a small wizard family.


    "Black and white tower, Fangcheng." Fang Cheng stroked his chest with his right hand and saluted.


    Andrew''s expression changed slightly when he heard Fang Cheng''s answer. Although he didn''t recognize the wizard robe Fang Cheng was wearing, he couldn''t have heard of the prestige of the black-and-white tower in this continent.


    "Lord Fang Cheng." Andrew looked more respectful.


    Fang Cheng nodded, picked up the purple ore in his hand and asked, "do you have a lot of purple gold ore?"


    Hearing the speech, Andrew nodded and replied, "yes, sir, our family has a small purple gold mine in the Holy Light empire. No matter how much adults need, we can provide it."


    The Holy Light Empire, which is the country where the floating island is located, is located below the floating island.


    The Holy Light empire is in the east of the continent, adjacent to the elf garden.


    Obviously, the wizard apprentice in front of us is the child of a small wizard family in the Holy Light empire.


    "What is the annual output of your family''s purple gold mine?"


    Hearing this question, Andrew was stunned and said, "Sir, what do you mean?" He''s a little confused.


    "I mean, I''ve covered all the purple gold mine you produce every year." Fang Cheng''s mouth was faint.


    "All... All inclusive?" Andrew was at a loss. Although his position in the family was not low, it was obviously not his decision. He hesitated for a moment and said, "Sir, can you leave us a contact address? I need to go back and discuss it with the elders of the family."


    "Yes."


    Fang Cheng nodded and left his room address at the Keaton hotel to Andrew. "I''ll be here during the exchange meeting. After discussion, I can come to me at any time."


    ......


    Fang Cheng searched for three days in the exchange meeting, and finally collected all the formula materials of the spirit of complaint potion. In fact, other materials of the spirit of complaint potion are not precious, but the main material spirit of complaint is relatively rare.


    But Fang Cheng''s space bracelet at this time has been filled with all kinds of grievances he needs.


    At this point, Fang Chengcai was relieved that his wizard road could continue.


    Three days later.


    Andrew took an old man with white hair to the door.


    Fang Cheng opened the door and saw Andrew and Andrew. He nodded and invited them in.


    After some greetings, several people entered the topic.


    "Lord Fang Cheng, I don''t know how many purple gold mines you need every year?" Like Phil, the old man who spoke was a white haired senior apprentice, but unlike Phil, he had completely abandoned the road of pursuing wizards and paid attention to the construction of the family.


    "I have said that no matter how many purple gold mines your family has every year, I can eat them." Fang Cheng said with a smile, "don''t worry about the problem of magic stone. In fact, I also have a small magic stone vein in my hand."


    Hearing the speech, the old man and Andrew looked at each other, and their eyes were hot.


    "Well, sir, because our family needs not only magic stones, but also other materials. It''s impossible to exchange all the purple gold mine for magic stones. I..."


    Fang Cheng directly raised his hand, interrupted his words and said, "is it enough with the enlightenment potion?"


    "Enlightenment potion?" The old man stood up excitedly.


    The most important resource for a wizard family is undoubtedly all kinds of wizard potions, but unlike other alchemy materials, wizard potions are usually firmly controlled by those large forces, and even those large forces themselves are not enough.


    For example, if Fang Cheng is in the high tower, it is difficult to buy the resentment elixir.


    Wizard potion is the most precious of all resources, because it is related to the transformation of the wizard''s own soul.


    "Yes, sir Fang Cheng, we promise you." The old man made a direct decision without procrastination.


    This made Fang Cheng a little stunned. It seems that he underestimated the temptation of enlightenment medicine to these apprentices.


    In fact, it is also because Fang Cheng has an intelligent learning machine and can make enlightenment potions himself that he underestimates the value of enlightenment potions.


    Otherwise, the apprentices of small wizard families do not know the formula of enlightenment potion or the materials of enlightenment potion.


    This kind of medicine can quickly increase mental power during entry-level and low-level apprentices. They have no way to get it at all.


    This is why many people want to break their heads and squeeze into the large wizard organization such as the black-and-white tower, because there are too many resources here.


    "In that case, let''s talk about the price."


    "OK..."


    Fang Cheng talked with Andrew and sent them out of the house.


    The small purple gold mine of Andrew family produces about 1 million tons of ore every year. Of course, when they don''t fully exploit it, Andrew promises that they will fully exploit the purple gold mine this time.


    In this way, the output will increase tenfold.


    In fact, Fang Cheng is still not satisfied. The main reason is that their family''s mining method is too backward. They still use manual mining. If Fang Cheng is entrusted to mine, it is estimated that the whole ore vein can be mined in less than a month.


    Fangcheng''s magic stone mine and disgusting metal mine have been mined almost.


    As for the price of purple gold ore, after fierce debate between the two sides, a magic stone of 100 tons of purple gold ore was finally set. You know, the density of purple gold mine is not low. It is estimated that a cubic meter of purple gold mine must weigh several tons.


    Finally, the two sides decided to change the payment method into half magic stone and half wizard potion, that is, 5000 magic stones and 100 enlightenment potions in exchange for 1 million tons of purple gold mine.


    Of course, if the Andrew family expanded production, the share of the transaction would be increased tenfold.


    The Andrew family now has more than 3 million tons of purple gold in the warehouse. Fang Cheng waved his hand and bought them all.


    Of course, these purple gold mines are far away in the Shengguang empire. The long way makes the transaction between the two sides not so convenient.


    For Fang Cheng''s magic stone and wizard potion, the Andrew family patted their chest and promised that their family would be responsible for transporting the purple gold mine. For a time, they didn''t want to expose Fang Cheng''s suitcase, and there was no good transportation method.


    If we could get the flying magic weapon from the floating island, it would be countless times more convenient to transport materials. Fang Cheng thought secretly.


    Then he thought that he had entered the structure and technical data of the spacecraft into the intelligent learning machine. After attending the exchange meeting, he could return to Anlu island and let the honeycomb laboratory develop such a flying magic weapon.
