Moreover, the yield rate of marrow washing pill is extremely low. Only one hundred parts of the material can successfully refine two or three pieces. Therefore, the price of this thing is not very expensive, and it is simply priceless. The current medicine master from the Tianhu Kingdom's Pharmacy Department is only provided to the royal family and large families, and is customized within the sect.

If this magical pill is really taken to the market, it will probably cost several million taels of silver to buy one.

Millions of taels of silver are dozens of times the total assets of Linjiabao! If it weren't for this ridicule system, the Lin family wouldn't have thought of getting one.

After knowing the purpose of these two pills, Lin Zhou changed his mind and immediately decided to spend 200 points of mocking experience points to upgrade these two marrow cleansing pills. This marrow cleansing pill is of no use for Lin Zhou, who is now replacing them with mocking experience points. He refines them for his father Lin Zhenlong and his grandfather Lin Xiaotian.

If these two marrow-cleaning pills, one helps his father Lin Zhenlong to advance from the peak of the eighth level to the early stage of the ninth level, and the other helps his grandfather Lin Xiaotian to advance from the early stage of the ninth level to the middle stage of the ninth level, then the future Lin family will have two ninth-level super strong men, and they can easily deal with the Zhao family generals, and the town master Gan Ba ​​can no longer underestimate Lin Family Castle!

Lin Zhou could not have ascended to the ninth level so quickly. The important task of protecting Lin Family Fort can only be handed over to grandfather Lin Xiaotian and father Lin Zhenlong.

"Help me upgrade these two Guben Pills." Lin Zhou said to Xiaofeng.

"Okay." Xiaofeng of course agreed.

"Now refine the Guben Pill..."

“Refining…”

“Ten, nine, eight, seven, six, five, four, three, two, one…”

"Congratulations on your successful refining! You have obtained: Marrow Cleansing Pill!"

After two consecutive times, the two Guben Pills in Lin Zhou's hand became two Marrow-washing Pills.

"The refining is successful...will there be a failure?" Lin Zhou asked Xiaofeng.

"Yes, these two elixirs just now have been refined into the Marrow Cleansing Pill, and the success rate is about 50%. Xiao Feng answered Lin Zhou.

"Damn! Only 50% success rate!" Lin Zhou was startled...

"What's wrong with fifty percent? As long as you can successfully refine one, you will make a lot of money. You were very lucky just now! Both of them were successfully refined." Xiao Feng said disapprovingly.

"That's true." Lin Zhou looked at the two marrow-cleaning pills in front of him with a strong medicinal aroma. Of course, he didn't want the refining to fail. In this way, his father and grandfather would have one. If the refining failed, only one person could get it.

I will make up some reason to send this marrow-cleaning pill to my father and grandfather, so that they can eat one separately, and maybe they can advance in the near future.

After putting the two marrow-cleaning pills into the wooden box, they were temporarily put aside. Lin Zhou started to study his dragon-slaying kitchen knife again.

The Dragon Slaying Kitchen Knife now only has the first grade. To reach the second grade, coke, sulfur stone, top-grade fine iron and other items and 150 taunt experience points; to reach the second grade to the third grade, these things are still needed, but the amount is larger. The top-grade fine iron is replaced with low-grade black iron, and the required taunt experience points have also increased to 200 points;

Among the materials required for the third grade to the fourth grade, the lower-grade black iron has become medium grade black iron, and there are also saltpeter and other substances, and the required ridicule experience value increased to 250 points; the fourth grade to the fifth grade requires the upper-grade black iron and more auxiliary materials, and the required ridicule experience value also increased to 300.

Tonghe Town is a small town famous for its minerals. There are many mineral smelters. You can buy various auxiliary materials needed to upgrade the Dragon Slaying Kitchen Knife. The main ones are fine iron and black iron, which are difficult to get. It’s okay to say that fine iron can be bought as long as you have enough silver, but black iron cannot. I guess you can only buy it by going to Yunsha City or Yunfeng County City and looking for a custom-made weapon refining family.

If it were someone else, even if these materials were prepared, the Dragon Slaying Kitchen Knife could not be upgraded to the grade. It would be necessary to find a weapon refiner to help you sacrifice and refine. However, with the help of the ridicule system, Lin Zhou only needed to find the required raw materials to sacrifice and refine the Dragon Slaying Kitchen Knife to improve the grade.

Find the first one, top-quality fine iron...

By the way, Lin Zhou suddenly remembered that after killing Zhao Yi, he got a broken bow and some fine iron arrow branches from Zhao Yi. Those arrow branches are made of top-grade fine iron, with a total of more than a dozen branches. They should be used as high-grade fine iron raw materials, right?

Lin Zhou took out the dozen or sophisticated iron arrows and took photos with a sarcasm system. It can indeed be used as raw materials! And the amount is very sufficient, almost five sophisticated iron arrows are enough to upgrade the dragon-slaying kitchen knife from first grade to second grade.

Although Zhao Yi's bow was blown up by a grenade, the material of the bow was an authentic low-grade black iron! I took a look at it again with the ridicule system. The black iron bow contained indeed low-grade black iron, just enough to upgrade the Dragon Slaying Kitchen Knife from the second to the third grade! This also solved it!

But if you want to upgrade the Dragon Slaying Kitchen Knife from third grade to fourth grade and fourth grade to fifth grade, you must find medium-grade black iron and top-grade black iron.

The black iron armor and black iron swords on the iron armor guards of Gan Ba, the town master of Tanghe Town, are all made of low-grade black iron. Only the armor on the town master Gan Ba ​​is made of medium-grade black iron, and the fifth-grade official sword in his hand is made of high-grade black iron. However, with Lin Zhou's current strength, the idea of ​​fighting Gan Ba ​​is purely seeking death.

I don’t think so much. I first use the existing materials in my hand to refine the first-grade Dragon Slaying Kitchen Knife to the third grade. The first-grade Dragon Slaying Kitchen Knife is already very powerful. After refining it to the third grade, it should be enough to compete with ordinary fourth-grade weapons, right?

Lin Zhou was idle now, so he simply called Lin Xuan and Lin Yuan and handed over the silver notes he had obtained from Zhao Hengjiang and Zhao Yi to him, and asked them to go out and help him purchase the materials needed to sacrifice and refine the Dragon Slaying Kitchen Knife. He himself went to the warehouse of Linjiabao, where dozens of damaged old weapons were piled up. Lin Zhou wanted to try his luck and use the mockery system to take a photo to see if they contained some black iron or something.

Unfortunately, there are only some low-quality fine iron weapons in the warehouse, and there is not even medium-quality fine iron, let alone black iron.

"Zhou'er, what are you looking for?" Lin Zhenlong happened to pass by the door of Linjiabao warehouse. He saw Lin Zhou coming out of it, so he asked him.

"I want to find some black iron." Lin Zhou didn't hide it from Lin Zhenlong. If Lin Zhenlong continued to ask, at worst, it would be said that the mysterious old man asked him to find it.

"Black iron? What grade? How much do you want? There is no in this warehouse. I'll ask you to go to the city to ask for you tomorrow?" Lin Zhenlong frowned slightly, but did not ask Lin Zhou about the specific purpose of his request for these things.

The value of one or two low-grade black iron is as high as a few hundred taels of silver, the value of one or two medium-grade black iron is as high as a few thousand taels of silver, and the value of one or two high-grade black iron is as high as tens of thousands taels of silver, or even tens of thousands taels of silver. It’s okay to say that the lower-grade black iron and the medium-grade black iron are always on the market, but the top-grade black iron is completely priced but not in the market.

"Each medium-grade or high-grade... costs at least seven or eight taels, right?" Lin Zhou smiled.

"Medium-grade and top-grade black iron? You can't buy it in the market... Zhouer, what do you want these things?" Lin Zhenlong was shocked. Unexpectedly, Lin Zhou actually wanted medium-grade and top-grade black iron, and he said seven or eight taels at the beginning! It would not be worth so much money to sell the entire Linjiabao!

"I just asked casually, want to play with a knife... Dad, please be busy." Lin Zhou smiled at Lin Zhenlong. When he spoke, he didn't expect Lin Zhenlong to get him a black iron. He was really just asking casually. Tomorrow's ancestor worship ceremony and martial arts competition, Lin Zhenlong will definitely be very busy tonight, so don't bother him.

"Okay." Lin Zhenlong nodded. Just as he was about to turn around and leave, Lin Zhou chased after him for a few steps and called out.

"What else is Zhou'er?" Lin Zhenlong looked at Lin Zhou with guilt, as if he was worried that Lin Zhou would propose something he could not do.
