"Some potions made with spirit materials will produce a chemical reaction when mixed with other materials!"
Xia Yibing was surprised: "Is this the powerful developer?"
The crow began to speak vaguely: "Well... about the same..."
In fact, she wasn't quite sure.
After all, she is an old antique who has just awakened not long ago. There are so many new things to learn every day. In terms of potions... she doesn't have the time to memorize such niche knowledge.
"Will do."
Hitzfeld said as he poured the medicine into the container, "Almost all of them will have a reaction, but the reaction will be very, very, very weak, and difficult to detect with the naked eye."
Heidi was about to ask why they had to do this, but then she remembered that the Count Xieyang in front of her had unusual eyes.
Details that are difficult for ordinary eyes to capture, maybe if it were that eye, it would be able to see them?
So that's why she wants to do this kind of experiment...
She conducted the same contact experiment on pencil leads, small stones, and black powder separately - no matter what reaction they produced after coming into contact with the drug, it was enough for her to make sure that the reaction was the same.
Others also understood it - it was indeed simple and did not require any professional knowledge at all.
The progress of the experiment is also proceeding as they expected.
Because it was just a very simple contact experiment, the results could be obtained by simply soaking the experimental materials in three solutions of the same nature, so the progress was very fast and it was completed within a few minutes.
“It’s the same…!”
Hitzfeld exhaled and spoke in an excited tone.
She used her divine eyes to see clearly that the small stones and black powder would produce fine bubbles when soaked in the solution.
The reaction is the same, so it can be basically confirmed that the two are made of the same material.
As for the refill...because it is just graphite and not graphene, the number of bubbles produced after soaking is far greater than the previous two, so it cannot be confirmed that the previous two are of the same origin as it.
Damn, how is handmade graphene prepared?
Looks like it needs to be taped?
But the problem is that there is no such thing as transparent tape in this damn era. Where can I get the tools?
"Do you suspect they are carbon steel?"
The Blood Crystal Crow suddenly spoke.
Hitzfeld and the others all looked at her.
"'Carbon steel'...?"
"I'm not sure." Crow refused to take the blame. "I don't know much about this... I just think it's a bit like a mineral discovered by Harwin."
Xia Yibing was dissatisfied: "Why didn't you say so earlier?"
"Who knows what the little brat gave you is for? If it were you, would you care?"
"stop fighting."
Hitzfeld stopped them and looked at the crow seriously.
"Can you tell me in detail how that 'carbon steel' was discovered and manufactured, mentor?"
"I'd be honored to teach you more."
Blood Crystal Crow really liked this gentle, cute and considerate little student. She immediately told everyone all the knowledge points she knew - of course, mainly to her beloved student.
"'Carbon steel' is made from carbon ore. It requires specific conditions. One is stable crystalline metamorphic rock, and the other is methane, methane in a high temperature environment."
"Crater?"
"Undersea volcano?"
Hitzfeld and Xia Yibing shouted one after another.
The "crystalline metamorphic rock" mentioned above may sound a bit confusing, but when it comes to methane in high-temperature environments, isn't this the most common in volcanic environments?
As it happens, they are no strangers to volcanoes.
Especially the submarine volcano... They were almost swallowed up by the largest submarine volcano in history. Hitzfeld also read the research materials on the geological ecology near the submarine volcano later.
"How?"
Xia Yibing and the girl stared at each other.
There might be a chance to try other methods, but the one Crow mentioned involves both methane and high temperature...
Their means are all "ice", and they are in the Arctic glacier with a temperature of dozens of degrees below zero. Where can they get high temperatures?
"give up."
Hitzfeld made the decision.
"It's enough to determine that it's made of the same material as this stone. Griman or someone else may have been underground. We can definitely get out by going up here."
Getting out is the most important thing right now.
Things like graphene and new materials can be considered later.
But Hitzfeld did still have some doubts in his heart.
The instructor said before... Heidi's true form couldn't be an ice orchid but a tropical plant.
Now, a new natural crystalline material has emerged that is suspected to require a high-temperature environment to be produced.
Tropical and hot.
How can these two affixes be combined with Arctic glacier? They are completely opposites.
The first time, you could suspect that the instructor remembered it wrong, but what about the second time?
It's impossible for so many coincidences to happen at the same time, right?
Combining the known information, Hitzfeld gradually came up with an incredible guess in his mind.
But this is just speculation for now.
It's useless to say it.
She kept it to herself for the time being and climbed the tunnel with the support of her companions.
After walking like this for nearly two hours and making several forks in the road, they finally and fortunately heard the sound of the wind.
It was not just a gentle breeze, but a very obvious whistling and sobbing. It did sound very creepy, but everyone's face was filled with joy and they couldn't help but quicken their pace.
“It’s coming out—Ugh!”
Xia Yibing poked out the snow that was blocking her head and dug her head out from the snow. Just as she was about to take a breath, her mouth was almost filled with snow.
The wind and snow in the world above ground have not stopped.
After coming up, all they saw was pitch black. Without a flashlight, they couldn't even tell left from right. Xia Yibing couldn't help but worry again, wondering if they had lost their way on the ice.
"That's South."
Heidi relieved her of her worries.
"It is indeed difficult to see in the polar night, but this is no problem for the tree people born here."
"And judging from the outline of the flashlight, there should be a dark forest on the right. We should be able to tell it by cutting down the tree trunks and looking at the growth rings. I suggest we go in and hide from the wind and snow."
That's a good suggestion.
No one likes to be out in the cold, so they did it immediately.
"I began to doubt whether it was right or wrong to obey you and come here..."
Sitting behind the trunk of a black pine tree, Xia Yibing took off her backpack and began to count the items inside.
She was not very panicked. Those people from the Ice Lake did not dare to walk close to the woods because they were afraid of the beasts living there. But they were not afraid. As long as they wanted to leave, they could just head south. There was nothing here that could stop them.
But she was worried about Hitzfeld.
Strictly speaking, they were worried about whether something might happen to the girl's stomach in such an extremely cold environment.
Her eyes were fixed on the scene below. Hitzfeld blushed a little and whispered, "I didn't expect it to be so troublesome..."
Xia Yibing is worried, isn’t she worried?
If she got pregnant, or if something happened, she wouldn't know how to deal with it.
All she could say was that the premonition was too strong, like some kind of call beyond her sixth sense, deeply embedded in her soul, forcing her to come.
"It's nothing actually."
Seeing that she had surrendered, Xia Yibing moved over and hugged her in her arms.
Rub the little face.
Well, it’s still warm.
"At worst, I can have more children after I go back..."
"If Eric and the others can do it, I don't believe we can't do it..."
Hitzfeld's eyelids twitched a few times and his face tended to get redder.
Suddenly, Heidi's call came from the front.
This guy was wandering around with Lily and the Blood Crystal Crow, saying that he was trying to hunt some prey or find some edible fern roots. How could he make such a noise...? Was he calling us over?
Without delay, the two of them quickly ran in that direction, passing through the dense but snow-covered woods, and saw Heidi and a big white dog squatting under a tree, and another person was leaning against the tree trunk?
survivor?
After looking at each other, the two of them rushed over faster and recognized at a glance that the person leaning against was Esther!
Poor Esther, she is only about fifteen years old this year... She is not even an adult yet, and her physique cannot be compared with theirs. In addition, she is likely to have been separated from the others. She has no idea if she has eaten in the past two days. She has fallen into a semi-comatose state, and the skin on her forehead is burning.
Fortunately, I didn’t suffer from hypothermia.
After roughly checking her physical condition, they finally breathed a sigh of relief.
It was dozens of degrees below zero, with no shelter, and she had only thick clothes and her body to withstand the temperature. She was still unconscious, but she didn't suffer from hypothermia. Either she was unconscious and lost control of her body for a short time, or she was just lucky.
"She's the only one?"
Hitzfeld asked Heidi.
"What about the two male students?"
"Where are her friends?"
The most important thing is - where is Robbo?
"Don't look at her, she's the only one there." Heidi pointed in the direction behind.
"I came around from that side. First I saw a big backpack on the ground. I knew there might be a survivor nearby. I walked a little further and saw her lying here."
"As for the others, nothing was found during the search."
Physical limit?
Xia Yibing thought.
It goes without saying how important a backpack is in this environment. Even if she is just an inexperienced 15-year-old girl, she should know the consequences of abandoning supplies.
But she still did it, you can only say that she was too tired.
She may have walked alone in the snow for a long time with this big bag on her back, feeling tired and hungry. There was no flashlight, and the woods were pitch black. From time to time, one could hear the whistling wind through the woods...
She must be terrified, right?
He was completely exhausted both physically and emotionally, so he threw away his backpack in an attempt to lighten the burden, perhaps hoping that this would help him get out of the woods faster.
Hitzfeld asked the others to look after Esther first, and he opened the big backpack and checked the contents.
I was pleasantly surprised to find a medium-sized tent inside.
This was a timely help for both them and Esther. They immediately worked together to set up the tent behind several tree trunks, carried Esther in, and then went in themselves. The wind and snow disappeared immediately.
Without wind, air flow is greatly slowed down and the temperature is retained.
He used the matches he found in his backpack to light a pocket stove to boil water, then broke up some dry food biscuits and dried meat and mixed them into the hot water to make a paste, and then he reluctantly fed Esther some food and water.
Her condition was visibly improving, and she opened her eyes more than an hour later.
"You are……"
