What should I receive from Xianjian 3 Pawnshop? Tell me what D to A received respectively! Thank you. It's kind of communication.

Rule 1: When high-grade items are unique, no matter how many times you buy them, you can only get one unique antique, at most one attribute item. If you get jellyfish essence in D, no matter how many times you buy it, you won't get snake gall, including other attributes. At level C, each business direction can get at most two kinds of attribute items, and there is no test data at level A and level B.. Rule 2: Pawnshops are divided into grades A to E that we can generally see, but. . . According to the amount of investment at each level, the items that can be purchased by 2000 units (that is, the number of items that can be increased or decreased by a fine adjustment of the mouse) are also different. For example, the investment of 15~25W is Grade D. Suppose you invest 249,000 yuan (the mantissa can't be remembered) and buy it several times. If the antique you get is Luoshen map and the attribute item is jellyfish essence, then no matter how many times you buy it, you won't get Yan Shedan or carved white jade cup. Rule 3: Randomness. I don't need to elaborate on this. After receiving the golden cicada for the first time during the test, quit the game to read the file and invest the same amount. The result is completely different. Rule 4: There is a high probability that if this file can get what you want, it will get it about ten times. If you still don't get it after more than 20 times, you don't need to try again. Rule 5: After the related investment between Grade B and Grade A (in fact, it is only for Grade B, the reason is needless to say, haha), the management policy is "north and south groceries", and it has been acquired for more than ten times. If you can receive the golden cicada, congratulations, you can receive all the remaining golden cicadas at this level by changing the direction. Rule 6: The quota (here "quantity" refers to value and price) has not been carefully demonstrated, but once I saw the golden cicada slough when I bought it, but I accidentally cancelled it. I kept buying, and then I won't get golden cicada slough again-maybe I saw it at first? Said a lot, in fact, the method is very simple: invest 249 thousand (from high to low, always feel that high return on investment is high, pure feeling, no reference value, hehe) to buy more than ten times. If you receive an item with other attributes, you can directly return the file and invest 247,000 yuan to try again. . . If you don't receive any advanced items, please try again several times. The probability is hard to say, hehe. If it has not been obtained for more than 20 times, it will be returned; If you receive it, file it. When I invested 2 17000, I received golden cicada slough and white porcelain flask (only test data, no reference value). I continued to invest 250,000 ~ 399,000 yuan, and was promoted to Grade C. I set the business direction as "north and south groceries" to continue the above process. Class C can only receive one golden cicada slough. String 5 continues to invest 400,000 ~ 499,000, and is promoted to Grade B. If you continue the above process and receive golden cicada slough, you can receive two if you continue to buy Grade B in another direction. If you invest 50W in Grade A, except for the "magic bullet", all the other three commercial policies can receive a golden cicada. In this way, four grades can receive seven golden cicadas in turn: 1, 1, 2, 3.
