"How can the threaded meat be removed without damaging the threaded shell?"

"How do blackheads remove blackheads without damaging them?"

"How can I increase the stability of a parallel structure?"

Standing in front of the light curtain in the help area for a long time, Lu Fan realized that he had really picked up the system in his brain.

These problems in the help area, in addition to medicinal herbs, runes, and even the problem of offering a reward for a personal information, can be described as strange.

However, those questions about medicinal materials and runes are available in both "Foundation of Plants and Trees" and "Foundation of Runes", of course, because Lu Fan only got a part, so he can't fully answer these questions, but even if he answers the questions he knows, it is enough for him to have a lot of contribution points, because the reward for these contribution points is not low.

The reason why he hasn't solved the problem is just because he doesn't know which one to answer, and if he shows too much strength, he may be detrimental to himself.

The help area is not far from the trading area, and that Baishi is still waiting in front of the trading area at this time, seeing Lu Fan standing motionless in front of the light curtain in the help area, of course he knows what is going on, it must be that Lu Fan can't answer a single question, but he doesn't want to lose face, so he stands there still.

Encountering such a person who wants to save face, Bai Shi is also very helpless, if he is not full of curiosity about the hemostatic agent refined by Lu Fan, he will never spend time wasting time with such a person, his time is very precious.

The beauty behind the counter has been paying attention to Lu Fan because she has no business, and when she saw Lu Fan looking at the light curtain stupidly, she also shook her head secretly, and then withdrew her gaze, such a person is really not worthy of her attention.

"Brother Lu, don't die to save face, 200 contribution points are enough for you to gain a foothold in the White Tower, if your recipe is really useful, after I succeed, I will give you another 200 contribution points, how about it?"

Bai Shi, who was a little anxious in his heart, came to the help area again, if it wasn't for Lu Fan's request, he really wanted to beat Lu Fan, in his heart, wasting his time was wasting his life.

Lu Fan glanced at Bai Shi lightly and shook his head secretly, in this world, some people always feel good about themselves like this.

Thinking of this, a figure inexplicably appeared in Lu Fan's mind, it was the inexplicable man who was driving the flamingo to warn him, with the appearance of this figure, Lu Fan's impression of Baishi dropped a notch again, and he didn't even want to say anything to the other party.

Click on a title on the light curtain, and with Lu Fan's operation, a small light curtain will automatically pop up in front of Lu Fan, and in addition to the questions in the help area that Lu Fan clicked on, there is also an answer box.

Without further hesitation, Lu Fan wrote directly in the answer box: "The threaded meat is crispy and loose, and the threaded meat shell is hard and strongly alkaline. ”

"Although the threaded shell will also be corroded by weak acid because of its alkaline nature, as long as formic acid is added to the weak acid, the formic acid will react with the threaded shell to form a strong shell, which can protect the threaded shell from being corroded by weak acid."

"After removing the threaded shell, the strong shell formed on the surface of the threaded shell can be removed by using NAOH melt to obtain a complete threaded shell."

After writing, Lu Fan directly clicked submit, and then clicked on the next question.

Although the name of threaded meat is threaded meat, it is really useful, in fact, it is the shell of threaded meat, the shell of threaded meat is one of the main ingredients for refining the bone shaping pill, and if the threaded meat is not removed, it will seriously affect the medicinal properties of the threaded shell, so how to take out the threaded meat as much as possible without damaging the threaded shell is an important topic for pharmacists.

Of course, Lu Fan, who became a monk halfway, didn't know that he was able to realize the preciousness of his "Foundation of Plants and Trees" and "Foundation of Runes", and it was only because he saw these problems.

In fact, the acid-base neutralization method proposed by Lu Fan is not that no one has tried, but either these people did not use formic acid, did not form a hard shell, and the threaded shell was also corroded; Either after these people used formic acid, because of the existence of a hard shell, the threaded shell also lost its original properties.

Formic acid and NAOH melt can be used at the same time, but none of them are available.

After answering five or six questions in a row, Lu Fan stopped, he only answered questions about plants and trees, at this time, he didn't want to expose too much, at this time, he was like having a treasure mountain, and he didn't have the ability to protect these riches at all.

Then he didn't pay any attention to Shiraishi on the side, and went straight to find his room.

Because answering these questions needs to be verified before he can get the contribution points of the bounty, but Lu Fan has absolute confidence, and there is nothing wrong with his questions, so now he only needs to go back to the room and wait for the contribution points to arrive, and he can start refining blood suppressants and selling them for money.

What's more, on the front line, because of the rich free energy, cultivating here is also a good choice, even if you don't cultivate, it's good to review and review the "Foundation of Plants and Trees", "Rune Basics", or study the Hui Yuan Dan.

His Lu Fan's time is also precious!

Because Lu Fan answered the question, the light curtain was only in front of Lu Fan, and Bai Shi on the side didn't see what Lu Fan had written, but he never believed that Lu Fan could answer those questions.

Because although he didn't see what Lu Fan answered, he saw clearly the questions that Lu Fan clicked on, those questions, not to mention Lu Fan, even those senior pharmacists of the Bai family, couldn't answer them.

And Lu Fan's direct going to you made Bai Shi extremely annoyed, he couldn't figure out how a person could have reached this level if he wanted to save face.

After being angry for a while, he was relieved, he knew that without contributing Lu Fan, he would not be able to live in Baita anymore, so Lu Fan still needed to find him in the end, he just needed to be a little patient.

A sneer appeared at the corner of his mouth, he had already decided, when Lu Fan came to him again, he must teach Lu Fan some lessons, he wanted Lu Fan to know that he would end up pretending to be forced in front of him.

The beautiful woman behind the counter in the trading area was also a little crying and laughing at this time, watching Lu Fan pretend to click on the question in the help area, and then answered, her thoughts were the same as Baishi, Lu Fan was just pretending.

The reason why those questions can hang there is because no one can answer them at all, and even the person who posted the question did not expect anyone to be able to answer it, and the reason why they were posted was just to ask for comfort.

And after Lu Fan finished pretending, he still didn't choose to trade with Baishi, which really made this beauty cry and laugh, this really answered the sentence, die to save face and suffer guilt!

She knew that Lu Fan would definitely regret it.
