Moreover, the medicine rate of the Myelin Cleansing Pill is extremely low, and only a hundred copies of the material can successfully refine two or three, so the price of this thing is not ordinarily expensive, it is simply priceless and not marketable, and the current medicine venerable of the Tianhu Country Refining Department is only for the royal family, the big family, and the big sect to customize internally.

If this kind of elixir is really on the market, it is estimated that it will cost several million taels of silver to buy one.

A few million taels of silver, which is dozens of times the total assets of the Lin family! If it weren't for this mocking system, the Lin family wouldn't have wanted to get a single one with all they had.

After knowing the use of these two pills, Lin Zhou's mind turned, but he immediately decided, and spent two hundred points of taunting experience points to upgrade these two solid pills into marrow cleansing pills. This myelin cleansing pill is of little use to Lin Zhou, who is now relying on taunt experience points to upgrade, and he re-refined them for his father Lin Zhenlong and grandfather Lin Xiaotian.

If these two marrow cleansing pills, one helped his father Lin Zhenlong advance from the peak of the eighth order to the early stage of the ninth order, and the other helped his grandfather Lin Xiaotian advance from the early stage of the ninth order to the middle stage of the ninth order, then the future Lin family will have two ninth-order super powerhouses, and they will be able to deal with the Zhao family with ease, and the town lord Gan Ba can no longer despise Lin Jiabao!

It was impossible for Lin Zhou to rise to the ninth order so quickly, and the heavy responsibility of guarding Lin Jiabao could only be handed over to his grandfather Lin Xiaotian and father Lin Zhenlong for the time being.

"Help me upgrade these two Gubendan. Lin Zhou said to Xiao Feng.

"It's good. Of course, Xiaofeng agreed.

"Now refine...... Guben Dan

"...... in Refining"

"Ten, Nine, Eight, Seven, Six, Five, Four, Three, Two, One......"

"Congratulations on your successful refining! You've got: Purifying Pill!"

After two consecutive times, the two Guben Pills in Lin Zhou's hands became two Purifying Pills.

"Refining success...... Will there be a refining failure?" Lin Zhou asked Xiao Feng.

"Yes, just now these two Guben Pills were refined into the Pulp Cleansing Pill, and the success rate was about fifty percent. Xiaofeng replied to Lin Zhou.

"Damn! There is only a 50 percent success rate!" Lin Zhou was startled......

"What's wrong with 50 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 have been successfully refined. Xiaofeng's tone was disapproving.

"That's just as well. Lin Zhou happily looked at the two medicinal fragrant marrow cleansing pills in front of him, of course he didn't want the refining to fail, so that his father and grandfather would each have one, and if the refining failed, only one person could get it.

Later, I will make up some reason to send this myelin-washing pill to my father and grandfather, and let them eat one each, maybe they will be able to advance to the next level in the near future.

After the two myelin cleansing pills were put into the wooden box and put aside for the time being, Lin Zhou studied his dragon slaying treasure kitchen knife again.

The Dragon Slayer Kitchen Knife now only has one grade, and upgrading to the second grade requires coke, sulfur, and high-grade refined iron and 150 taunt experience points;

Among the materials required for the third grade to the fourth grade, the lower grade Dark Iron has become the middle grade Dark Iron, and there are more saltpeter and other things, which increases the required taunt experience points to 250 points, and the fourth grade to the fifth grade requires the upper grade Dark Iron and more auxiliary materials, and the required taunt experience points have also been increased to 300.

Barrel River Town is a town famous for minerals, there are many mineral smelters, and all kinds of accessories needed to upgrade the Dragon Slayer Treasure kitchen knife can be purchased in the town. The main ingredients are mainly refined iron and dark iron, which are more difficult to obtain. Jingtie is good to say, as long as there is enough silver to buy, Xuantie is not good, it is estimated that only by going to Yunsha City or Yunfeng County City and looking for a refining family to customize it can be purchased.

If you change to someone else, even if these materials are ready, you can't make the Dragon Slayer Treasure Kitchen Knife upgrade to the level, and you have to spend a sky-high price to find a refiner to help you refine it. But with the help of the taunt system, Lin Zhou only needs to find all the raw materials he needs, and he can refine the Dragon Slayer Treasure Kitchen Knife to improve his level.

Let's find the first one, high-grade fine iron......

By the way, Lin Zhou suddenly remembered that after killing Zhao Yi, he got a remnant bow and some fine iron arrows from Zhao Yi. Those arrows are all made of high-grade fine iron, and there are more than a dozen of them, so they should be able to be used as high-grade fine iron raw materials, right?

Lin Zhou took out the dozen or so fine iron arrows and took them with the taunt system, and sure enough, they could be used as raw materials! And the amount was very sufficient, almost five fine iron arrows were enough to upgrade the Dragon Slayer Treasure kitchen knife from the first grade to the second grade.

And although Zhao Yi's bow was blown up by a grenade, the material of that bow was an authentic low-grade Xuantie! I took a look at it again with the taunt system, and the amount contained in this Xuantie bow was indeed a low-grade Xuantie, which was just enough to upgrade the Dragon Slayer Treasure Kitchen Knife from the second grade to the third grade!

But if you want to upgrade the Dragon Slayer Treasure kitchen knife from three to four, four to five, you must find a medium-grade Xuantie and a high-grade Xuantie.

The Xuantie battle armor and Xuantie battle knives on the ironclad guards of Gan Ba, the town lord of Barrel River Town, were all made of low-grade Xuantie. Only the set of battle armor on the town lord Gan Ba was made of medium-grade Xuantie, and the fifth-grade official battle knife in his hand was made of high-grade Xuantie. However, with Lin Zhou's current strength, the idea of fighting Na Ganba is purely looking for death.

I don't want to think so much, let's use the existing materials in my hand first, and refine the first-grade dragon-slaying treasure kitchen knife to the third-grade. The first-grade Dragon Slayer Treasure kitchen knife is already very strong, and after refining 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, handed over the silver and silver tickets he got from Zhao Hengjiang and Zhao Yi to the two of them, and asked them to go out to help him buy the materials needed to refine the Dragon Slayer Treasure kitchen knife. He himself went to the warehouse of Lin Jiabao, where dozens of damaged old weapons were piled up, and Lin Zhou wanted to try his luck and take a photo with the taunt system to see if they contained some dark iron or something.

It's a pity that there are only some weapons made of low-grade fine iron in the warehouse, and there are not even medium-grade fine iron, let alone dark iron.

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

"Looking for some darkiron. Lin Zhou didn't hide it from Lin Zhenlong, if Lin Zhenlong continued to ask, it would be a big deal that the mysterious old man asked him to find it.

"Xuantie? What grade? How much do you want? There is no one in this warehouse, tomorrow I will let people go into the city to help you ask?" Lin Zhenlong frowned slightly, but did not ask Lin Zhou about the specific purpose of these things he wanted.

The value of one or two lower-grade Xuantie is as high as several hundred taels of silver, the value of one or two medium-grade Xuantie is as high as several thousand taels of silver, and the value of one or two high-grade Xuantie is as high as tens of thousands of taels or even hundreds of thousands of taels of silver. It is good to say that there will always be some of the low-grade and medium-grade blackiron, but the high-grade darkiron is completely priceless.

"Medium and high-grade, each...... At least seven or eight taels, right?" Lin Zhou smiled.

"Medium-grade and high-grade dark iron can't be bought in the market at all...... Zhou'er, what do you want these things for?" Lin Zhenlong was taken aback, he didn't expect Lin Zhou to actually ask for medium-grade and high-grade Xuantie, and as soon as he opened his mouth, it was seven or eight taels!

"I'm just asking casually, I want to play with a knife...... Father, please be busy. Lin Zhou smiled at Lin Zhenlong, he didn't expect Lin Zhenlong to get him Xuantie when he spoke, he really just asked 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, and was about to turn around and leave, when he was stopped by Lin Zhou after a few steps.

"What's the matter with Zhou'er?" Lin Zhenlong looked at Lin Zhou with some humility, as if he was worried that Lin Zhou would propose something that he couldn't do.
