In fact, there is no need to study it so carefully, that is, just now after Yu Fei asked the spear god to put the materials into the iron furnace, he was disturbed by the cry of the kitten, and did not operate the iron furnace. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The material is placed on the edge of the furnace, plus the furnace heating is not controlled. That's why I failed to build the Sharpstone and only gained a little proficiency, and the material could be recrafted.

A few minutes later, Yu Fei had already determined the cause of the special situation just now and tried to build it.

Yu Fei first asked the spear god invincible to put the material on the edge of the iron-striking furnace and then clicked to build, and no longer operated the temperature of the iron-striking furnace, leaving it at a very lower temperature than usual.

Two minutes later, Yu Fei received a system prompt.

Grinding Stone Forge failed!

You gain 1 crafting mastery!

Sure enough, Yu Fei was a little happy at this time. And pick up the materials you just created and continue to build.

After more than half an hour, Yu Fei relied on that set of materials to make the gun god invincible and gain 13 proficiency points.

By the time I gained the 14th proficiency point, the set of materials finally became unusable.

"I'm Nima! How so! ”

Yu Fei felt that this would not work, not because a set of materials could only be used 14 times and could not be used again. If this is the case, Yu Fei can make the material farther away from the iron-striking furnace, and make the temperature of the iron-striking furnace lower, which can increase the number of times or even dozens of times of use.

Rather, it's because a little proficiency takes two minutes. Two minutes may seem like a short time, but 50,000 two minutes is a long time.

If you do the math, if you keep building 24 hours a day, it will take at least 70 days to become a gold builder.

However, Yu Fei's half-hour time was not in vain, at least it made Yu Fei understand that if you want to deliberately use this method to build, the success rate is 100%. Unlike crafting a Rare Sharpstone, there is a good chance that it will not succeed.

Time passed minute by minute, and Yu Fei was still studying carefully in front of the computer. The kitten next to him nestled in his hat and watched Yu Fei quietly, not moving or saying a word.

Chen Tianzhou didn't bother Yu Fei either, he had his own things to do.

In the Internet café, two teenagers are focused on their respective computers, engrossed in their own affairs.

Before he knew it, it was noon, during which Yu Fei tried a few more times, he let the materials get a few points closer to the center of the iron furnace, and also tried to make the temperature of the iron furnace a few degrees higher.

Yu Fei's time for these builds has been shortened a lot, but it is still not ideal. And the material is also used a lot less often.

There was even a time when the material was used twice and then it could not be used. It is better to make it directly into a fine grinding stone, so that it can at least be used to sell.

Just when Yu Fei was still thinking about it, there was a knock on the door.

"Who! The Internet café is closed today! Please find a different path! Chen Tianzhou said.

"Black-hearted porridge! Open the door! Let the old lady in! ”

Chen Tianzhou heard Tang Shanshan's voice, and reluctantly opened the door a crack.

Yu Fei also recovered from his research at this time.

I saw Tang Shanshan and Xiao Xiaoyue carrying a takeaway in all four hands.

"It's yours! Yu Fei's share is in Xiao Xiaoyue's hands. Tang Shanshan slapped a takeaway in her hand on the table in front of Chen Tianzhou and said.

"Can't you be gentle! Look at Xiao Xiaoyue! Gee! How nice! Look at you again! Gee! Of course it's even better! Chen Tianzhou made a divine turn and kept his share of takeaway.

Xiao Xiaoyue listened to Chen Tianzhou's words, and her already ruddy face became even more ruddy.

"Black-hearted porridge! I'll drive two machines for us! Tang Shanshan said unceremoniously.

"Okay! Yes! Yes! Feel free for you! Chen Tianzhou gobbled up the takeaway perfunctorily.

After Xiao Xiaoyue gently handed the takeaway to Yu Fei, Yu Fei didn't gobble it up like last time. Instead, a few pieces of meat were placed in a plastic bag and placed in front of the kitten.

"Yu Fei! Did you pick up this kitten? Xiao Xiaoyue sat next to Yu Fei and touched the kitten's back with her hand.

"Meow~Meow~" The kitten was anxious to eat it after seeing the meat in front of him, but the kitten's neck was too short, its mouth couldn't get close to the plastic bag, and its hands weren't long enough.

Xiao Xiaoyue smiled and picked up the kitten, and picked up the plastic bag with one hand and put it in the kitten's mouth.

"Meow!" The kitten meowed twice.

"Ugh! Kitten! After Tang Shanshan saw the kitten, she jumped and walked towards Xiao Xiaoyue.

Yu Feike and Chen Tianzhou shook their heads in unison.

Girls! That's it!

......

After the four of them had eaten, Tang Shanshan and Xiao Xiaoyue seemed to be less interested in kittens. The game was played.

Yu Fei was still struggling to study how to make the Spear God invincible a gold-level builder at the lowest cost, and create a legendary weapon for himself that satisfies him.

About an hour later, the kitten seemed a little tired. Fell asleep lying in his hat. Tang Shanshan shouted in front of the computer, while Xiao Xiaoyue calmly operated the mouse and keyboard, the hand speed was not fast, but every key was very stable, and the control of the mouse was also very stable. There was nothing that made Xiao Xiaoyue panic.

Chen Tianzhou showed a lewd smile on his face, needless to say, that guy must have researched some evil rune combination.

"Black-hearted porridge! How many levels are you? Tang Shanshan asked.

"Taller than you"

After Chen Tianzhou finished speaking, he added: "But it's not much higher. ”

"Then you'll have to wait for me! I'm going to beat you to beg for mercy this time! Tang Shanshan clenched her fists and said.

"Just you! All right! I'm waiting for you! Chen Tianzhou smiled lightly.

There was a slight lewdness in the smile.

Yu Fei tried a few more times, but the effect was not very satisfactory, although he still had thirty or forty sets of materials left, but Yu Fei had to study a satisfactory effect, these materials were far from enough.

Another few hours passed, and it was almost 3 p.m. or so.

"Sanshan! I can't! I'll take a break, and you can play by yourself for a while! ”

Xiao Xiaoyue said and took the headphones off her head, closed her eyes and rubbed her temples with her hands.

"Holy! Still can't do it! Yu Fei failed in another experiment.

"Yu Fei! Are you in any trouble? Xiao Xiaoyue opened her eyes and approached Yu Fei's computer.

"Oh! I want to get stuck with a BUG to practice building proficiency, but it's always bad, and there's no way to grasp that degree. Yu Fei didn't raise his head, and his tone seemed to be talking to himself.

Xiao Xiaoyue said: "Yu Fei, let me take a look and see if I can help you." ”
