Time passed day by day, the school had Song Yu's father to say hello, and Chang Alfalfa also devoted himself to the development of this new type of weapon, the initial drawing after several simple model tests, has basically been considered stable performance, but now the most important thing for the three of them has become what kind of materials need to be used to ensure the normal use of the weapon, ordinary weapon production materials can not achieve perfect heat insulation, and the temperature is too high will definitely affect the use of weapons. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The model and principle have basically come to an end, now the most important thing is where to find such a material that can achieve perfect heat insulation is not bulky and can meet the power of the weapon, through continuous testing, long alfalfa found that although plastic and foam can be insulated, but it will affect the power of the weapon, if the two lightest thermal insulation materials are abandoned, and the fiber ceramic is used as thermal insulation materials, it will increase the weight of the weapon, affecting the user's feel and aiming accuracy.

After several unsatisfactory tests, Alfalfa's mood couldn't help but get nervous, he looked at the two of them with a bad face, and said slowly: "If you can find a series of materials that will not affect the power of the weapon and can achieve perfect heat insulation, it will be perfect!?"

Song Yu debugged the structure of the last test specimen and said slowly: "Well, what you said makes sense. But it seems that there is really no one that can find and use the thermal insulation medium that can do these two things perfectly!"

"Yes!?hey, what should I do?" said Alfalfa with a slow sigh.

After listening to the words of the two, Xia Yan couldn't help but smile and said slowly: "Don't worry, I'll think of a way for this thing you said! For now, you should continue to debug the structure of the weapon first! The problem of this material is covered by me!? Go and get busy with you? Don't worry about the rest!"

"Hmph, where are you going, where are you going to find it, can you find a material that my father can't find?" Song Yu obviously didn't believe Xia Yan's words, just thought that he was trying to curry favor with Alfalfa.

After looking at him suspiciously, the little abacus in his heart quickly moved, after all, Xia Yan is the prince of the demon clan, and there is no such thing in the human world, so maybe you can really find such a material through the demon world? Thinking of this, Chang Alfalfa couldn't help but nod and said, "Okay, then it's hard for you? Complete the task early, return to freedom early!?"

"En, don't worry, leave it to me!" Xia Yan nodded with a smile and said slowly.

Song Yu naturally couldn't believe him, and couldn't help shaking his head and said: "Although the weapons materials of our family's military research institute dare not be said to be the first in the country, but if we say second, no one will dare to say first!? Where can you find the materials that we can't find here?"

"Don't worry about me, just wait for me to get my things back, boy!?" Xia Yan glanced at Song Yu and said slowly.

Chang Alfalfa also smiled, nodded towards Song Yu, and said slowly: "Don't worry, I believe in him, you can also trust him! I believe that we will be able to finish it soon, and when we are both free, I will definitely treat you two well." ”

Song Yu was unhappy in his heart, firstly, he thought that Xia Yan was actually different from the scum he imagined, and secondly, Chang Alfalfa talked twice about being free, it seemed that he was really bored with the research institute at his home, if he didn't really ask for something, he would definitely not come to the institute to help, thinking of this, Song Yu's mood couldn't help but plummet, in fact, Song Yu didn't believe in Xia Yan, and there was indeed a realistic basis. However, Song Yu didn't know that maybe there was really something good in this demon world that could be used as this material. Anyway, no matter what, Long Alfalfa watched Xia Yan leave with confidence.

"You don't really believe that he can find the materials we want for you, do you?" Song Yu couldn't help but say urgently when he saw that Chang Alfalfa seemed to really believe Xia Yan.

Chang Alfalfa looked at Song Yu in confusion, and nodded slowly: "En, yes! I think maybe it's okay! Anyway, we don't have any other way now, since he can speak, then I think he should have a corresponding strategy to say such a thing!?

"Okay, since you choose to believe him, then I won't force you, I will seriously look for the materials for heat insulation, I can't just put the matter of finding materials on a person who can't reassure me!?" Song Yu seemed a little angry, but he shouldn't be blamed for being angry, the girl he liked said in front of him that he believed in his rival in love, and it was really strange not to be angry!?

Alfalfa was a little puzzled, hesitated for a while, and then said slowly: "Hey, I said you shouldn't always think about him with such a big prejudice, right?

"I know you believe him, but I just want to keep my own thoughts, so please don't force me to have the same thoughts as you, okay?" Song Yu's unhappiness in his heart became even stronger, and he slowly looked at the long alfalfa and said slowly.

Seeing that he was already in a bad mood, Chang Alfalfa swallowed back the words that came to his mouth, and slowly shook his head: "En, okay, I know, then I'll go and get busy first!

"Eh? I suddenly remembered a very important thing, when I was testing the trigger before, I found that the trigger didn't seem to be very reasonable, but I can't see what is unreasonable with the naked eye, and if you are free, take it to the military magnifying glass to check it and confirm whether there is a deviation?" Song Yu saw that Alfalfa's face also darkened, and he couldn't help sighing, and quickly changed the topic.

Chang Alfalfa hesitated a little when he heard this, and after a while, he nodded and said, "En, okay then, I'll check it later!?"

"Well, that's okay, you're busy, I'll go find the materials!?" Song Yu nodded and walked away slowly.

After sending Song Yu and Xia Yan away, Alfalfa could only shake her head and slowly return to the laboratory, and then devote herself to the revision of the design drawing, ***** the typical problem of the seat, she will have obsessive-compulsive disorder in everything, and she must force herself to do her best in everything! Of course, this is also one of the main reasons why Chang Alfalfa dared to bet with Song Yu's parents in the first place! (To be continued.) )
