Then, Su Bai and the old cat walked a little more in the forest, and when they saw that it was getting late, they found a place to camp, cut some branches, and built a shed that could barely shelter from the rain.

"How? Can you endure this suffering? The old cat covered his body with a plastic bag to maintain his body temperature.

"Okay." Su Bai also put a layer of plastic bag on his body and replied.

"It's a pity that it's raining today, and there is no dry firewood here, otherwise we could have made a fire to keep warm." The old cat said with a sigh.

"It's fine." Su Bai shook his head, he just obtained a little cold-resistant attribute today, and now this low temperature does not have much impact on him.

"You're in good shape." The old cat smiled, took off the backpack, and said, "Now that we have time, let's dispose of these herbs." ”

Along the way, they also got a lot of herbs.

"yes, okay." Su Bai nodded.

Then, the two of them took out the herbs and began to treat them roughly.

The herbs in the forbidden land are actually not easy to break.

However, it also needs to be systematically treated to prolong its preservation time, and the general treatment method is to attach soil to the roots of the herbs.

When dealing with it, the old cat also estimated the value of the herbs, a total of about 300,000.

"These herbs are for you." After handling the herbs, the old cat said to Su Bai.

Su Bai was stunned for a moment, and then said, "Why is this?" ”

He couldn't understand why the old cat would give him the benefits at his fingertips.

The old cat shook his head and said, "I am your guide, so I will naturally give you some benefits, and my original guide did the same to me, so you don't have to care about this." ”

Seeing the other party say this, Su Bai couldn't help but feel a trace of guilt in his heart, the other party was so sincere to him, and he also hid his ability.

In this way, it seems that some people can't stand it.

But soon, he threw this guilt out of the clouds.

He still felt that he knew his secrets well.

The other party is good to him, and he will return this friendship another day.

"Thank you very much." Su Bai nodded and said.

"Hehe, I just like your unpretentious look." Seeing this, the old cat smiled, and continued: "Since there is still time now, I will tell you about the specific matter of the pharmacist."

There are three steps in refining potions, and in the first step, you have to test the spiritual energy in the other person's body and know the specific attributes of the other person. Then use the medicinal materials to correspond to the other party's physical attribute points to refine the medicine.

The psionic attributes in the human body need some large-scale testing instruments to test them, and we don't have this condition now, so we can only use small instruments to roughly test, with an error of about 0.1%. ”

Speaking of which, the old cat took out a small palm-sized instrument from his bag.

When Su Bai heard this, he asked a little strangely: "Isn't there a magnetic field here, and many instruments can't be used?" ”

Hearing the other party's words, the old cat laughed and said, "If you change to other instruments, this is indeed the case." But my device, as well as our mobile phone, are all specially made, and you can take out your phone now and see if it works. ”

Seeing that the other party said this, Su Bai took out the black mobile phone and found that it really had no effect except that there was no signal.

"Let me tell you, just the mobile phone in your hand, and this instrument, each of them is a million-dollar thing, and there is a priceless market." The old cat pointed to the mobile phone in Su Bai's hand and his own instrument and said.

Hearing the other party's words, Su Bai was a little speechless, he really didn't think that mobile phones and instruments would be so expensive.

"Okay, let's not talk about that." Seeing Su Bai's appearance, the old cat opened the lid of the instrument in his hand, pointed to the needle inside and said, "This instrument, as long as it is pierced into the human body, will analyze the spiritual energy in the human body according to the human blood."

In terms of data, the error is about 0.1%, and after recording the psionic energy of that person's body, you use herbs to adjust the psionic entry potion according to the ratio of 1:10. ”

Saying this, the old cat paused for a moment, and then said: "The more consistent the data of the medicine and the human body, the greater the potential of the other party's development, on the contrary, the worse, and there is no room for promotion in the future."

And once the spiritual energy in the potion does not match the opponent's body, or even some attributes are exceeded, the opponent's spirit will be infected by the spiritual energy and become a murderer.

Therefore, a good pharmacist should estimate the psionic content of the herb and the psionic data of the human body. ”

Hearing the old cat's words, Su Bai also understood what the other party meant, and then he thought for a while and said, "Since this is the case, the error of this instrument is 0.1%, even if the pharmacist is powerful, it is difficult to debug the potion that must be in line with the human body's spiritual energy." ”

"Of course." The old cat nodded, shook his head and smiled: "You must know that in this world, no one can debug a sequence potion that must match the other party. All we can do is get as close as we can.

Moreover, the instrument I have in my hand is only the worst instrument, if it is better, it must be able to be accurate to 0.01, or even lower. But the instruments were so big that they couldn't be brought out. ”

"Okay." Su Bai also understood, then he thought about it, and asked again, "Is that kind of instrument very expensive?" ”

"Of course, an instrument capable of error of 0.01% needs about 20 million, 200 million for 0.009%, 1 billion for 0.008%, and 6 billion for 0.007%. Nowadays, the lowest error is 0.001% of the instrument, and there is only one, which is worth about 50 billion in Metropolitan University. The old cat said slowly.

Hearing the other party's words, Su Bai was a little speechless, he didn't expect that this kind of instrument would be so expensive.

And he, even if he can make money now, these are still astronomical amounts for him.

"But don't worry, the Federation has psionic instruments in various provincial capitals, and you can use them directly through the housekeeper to obtain permissions, but you just need some contribution points." It seemed that seeing that Su Bai was hit by the price, the old cat added again.

Hearing the other party's words, Su Bai finally felt at ease.

"The instruments in the provincial capital city, how much error are the instruments?" Su Bai looked at the old cat and asked.

"The error does not exceed 0.01%." The old cat said.

It was at this time that the sound ......of leaves scratching clothes came from a distance.
