In the past life, there are two kinds of materials related to fire protection, one is fire protection and the other is heat insulation. For example, ceramics have a very good fireproof effect, but not heat insulation. And foam resin or something, the heat insulation effect is very good, but the fire prevention is far worse, and it is almost the same as a ignition material.

If you just want one effect, this is not difficult, that is, Chen Pan can find a substitute in this world now, but if you want two effects together, it will be a little difficult. If in the previous life, it was possible to use thermal insulation materials to meet fireproof organic coatings, so that the purpose of fireproof and thermal insulation could be achieved, but in this world it is not possible.

Chen Pan thought for a while and couldn't come up with a way, and finally could only ask Qingxia: "Senior sister, what material did you use last time, can you show me?" Chen Pan didn't know much about the refining materials in this world, so just ask, maybe he can come up with a way.

"It's this kind of green jade. Qingxia took out a piece of cyan jade from her arms and handed it to Chen Pan, and then said stupidly: "Although the fire prevention effect is good with red fire jade, there is no way to emit the power of thunder and lightning. With purple thunder jade, although the thunder and lightning are very powerful, it can't withstand a few burns. ”

"Qinggang jade!" Chen Pan sighed in surprise, and then took it. He knew a little about this kind of jade, but he didn't understand it very thoroughly, after all, at his level, he could only come into contact with some very low-grade refining materials, and the several kinds of jade that Qingxia said were all medium-to-high-grade materials.

"Can you tell me about the nature of this material?" Chen Pan asked, asking if he didn't understand, this is a character inherited from his previous life. And Chen Pan also found one of his own shortcomings, when he was in the library, he devoted himself to refining methods and formations, but he neglected some important materials, and it seemed that he had to go back and make up for it when he found time.

Qingxia didn't care about Chen Pan's ignorance at all, and carefully told Chen Pan what she knew. After listening to what Qingxia said, Chen Pan was very surprised, he found that his understanding of jade was very shallow. In the memories of a previous life, jade was a compound of silicon and oxygen mixed with a small amount of metal, and it seemed to be very different in this world.

Speaking of this green jade alone, it can withstand the fire without refining. You must know that in the previous life, the fire was already equivalent to a flame of more than 8,000 degrees, that is, steel could be burned, not to mention jade.

After thinking for a while, Chen Pan said to Qingxia: "I can't think of a way for the time being, but can you help me find the Purple Thunder Jade and the Red Fire Jade, give me a few days, and I'll give it a try!" Originally, he just wanted to do Qingxia a favor, but now he was very interested.

Hearing that Chen Pan was willing to help, Qingxia immediately nodded: "No problem, you wait, I'll go back when I go." After saying that, he flew towards Yuxia Peak, and it didn't take long for him to fly back, handing Chen Pan a piece of purple and a piece of red jade.

"Senior sister, you can do it yourself, I'll find a way!" Chen Pan explained, and entered the room by herself regardless of Qingxia's situation. Qingxia was not annoyed, but just said: "You have to do your best, Uncle Gangzheng said that you should have a way!" After speaking, she left Jinshifeng.

It turned out to be the reason for Uncle Gangzheng, I said how could this aunt find herself. Chen Pan smiled, and then used the millisecond observation technique to look at the jade in his hand and study it.

For about half an hour, Chen Pan frowned and withdrew from the microcosm. From the point of view of composition, these jades are not much different from their previous lives, and the main composition is silicon-metal compounds, but there are some substances that Chen Pan cannot find from the periodic table at all.

Perhaps it was these substances that caused these jade stones to have these special effects, Chen Pan thought to himself. The periodic table is only based on the elements known to man, and it does not mean that there are only those elements in the world. After the beginning of the apocalyptic era of the previous life, every hundred years or so, scientists have always discovered several new substances. There are too many wonders in the universe, and human beings still don't know enough, and now in another world, it's normal for this kind of thing to appear that they can't understand.

Putting the jade in his arms, Chen Pan took the cable car to Zixiao Peak, found Qingzhu and informed Lei Ting Zhenren to apply for entering the scripture warehouse. There was the credit of the cable car before, and later he saved a group of disciples, but Lei Ting Zhenren did not refuse, allowing Chen Pan to enter the scripture library freely.

As soon as he entered the scripture library, Chen Pan went straight to the books related to materials, especially jade. After fighting like this for more than a month and reading all the books related to the materials, Chen Pan came out of the scripture library with satisfaction.

As soon as he came out, he found Qingxia waiting for him at the door, and when he saw Chen Pan, Qingxia immediately ran over: "How is it?

Chen Pan nodded, in fact, he already had a way, but there was still some time in the refining competition, so he was not in a hurry to come out.

"Really?" Seeing Chen Pan nodding, Qingxia immediately cheered in surprise.

"Don't worry, go back to Jinshifeng first, I'll teach you!" Chen Pan walked forward without hurry, visited Qingzhu first, and then left, these days he sent three meals a day to himself, to this senior brother, he is grateful from the bottom of his heart.

After returning to Jinshifeng, Chen Pan told Qingxia what he had thought of. Using the principle of the thermos flask in the previous life, the red fire jade was used as the shell, and the purple thunder jade was used as the inner tank. The difference is that the red fire jade is made into a multi-layer shell, and a vacuum is achieved between each layer, and a vacuum is also maintained between the outer layer and the inner tank. In this way, the red fire jade can basically ignore the incineration of the flames, and the multi-layer vacuum can isolate the heat, so that the purple thunder jade inside is not affected by the flames.

The reason is very simple, but Qingxia was very surprised after hearing it: "I understand what you said, but how can I do it?"

Chen Pan thought about it and decided to demonstrate it again, so that he didn't have to bother talking about it. took out the little black furnace from her arms and was ready to start, but Qingxia immediately exclaimed when she saw the little black furnace: "Black Pattern Jade Ding Furnace, why are you here?"

Chen Pan was stunned for a moment, this stove seemed to have a lot of origin, and asked, "Do you know this?"

Qingxia nodded: "Who doesn't know, this is the head of the black pattern Golden Ding Furnace, although it is not as good as the Chixia Immortal Furnace in Tanggu, it is also a genuine Xuan-level refining furnace, how can it be in your hands?"

Chen Pan gasped, this thing was given to him by Uncle Gangzheng, could it be that he stole the Thunder Real Man? If this is the case, it will be a big trouble. You must know that there are many levels of refining furnaces, those that do not enter the stream are not counted, and those who can be called good furnaces are divided into four grades, heaven and earth Xuanhuang. Not to mention the two levels of heaven and earth, it is a priceless treasure that cannot be estimated. Only Tang Gu has a ground-level Chixia Immortal Furnace in the East Pole Xuanzhou, and the heaven-level refining furnace is the strongest in the Ancient Continent, and it is only heard that no one can be sure whether it exists.

Aside from the two levels of heaven and earth, the two levels of Xuanhuang are also unattainable, even the yellow-level refining furnace is also priceless, not to mention the Xuan-level refining furnace.

Chen Pan didn't know that the stove in his hand was so precious, but he definitely didn't dare to admit it, so he hurriedly said without changing his face: "It's not that, it's just an ordinary stove, but it's a bit like, don't talk nonsense, I'll start demonstrating now, don't blame me if I can't learn it." After speaking, regardless of Qingxia's reaction, she put the two pieces of jade into the small black furnace and began to condense.

Seeing that Chen Pan had started, Qingxia stopped interjecting and just muttered: "Isn't it?
