[69 Book Bar-www.] "Haha, take a closer look at these balls." Wang Blacksmith said, handing the few small balls in his hand to Qin Feng's hand.
Lao Qin took them in his hand and looked at them carefully, but he didn't see any tricks.
Wang Blacksmith smiled and said, "Qin Feng, the reason why these balls have different colors on the outside is because the materials wrapped on the outside are different!"
Qin Feng was a little confused, "Uncle, what do you mean is that the inside of these balls has not melted, but the outside is the part of the material that has melted before?"
Wang Blacksmith was still organizing language and wanted to find a more popular saying, but he didn't know that Qin Feng suddenly came to the point, which surprised him a little.
"Qin Feng, can you actually think of these?"
"What's wrong, isn't it right?" Qin Feng was a little confused. He seemed to have grasped some of the reasons for the failure, but in a daze, he disappeared without a trace.
"Yes, very right. You talked about the key point. You have been learning the art for a short time. You may not know that every material has its melting temperature. Only when it reaches this temperature can this material melt completely.
But if the temperature is too high, these materials will be lost. Just like the black smoke rising from the furnace before, they are signs of material loss at high temperatures."
As soon as Wang Blacksmith said this, Qin Feng understood it completely. This is the melting point and gasification in physics. No matter what substance it is, as long as it is a single substance, it has its own melting point. If the temperature is too high, gas will appear.
The phenomenon of transformation and the black smoke is caused by gasification.
Qin Feng told Wang Blacksmith about his thoughts. When he heard the fresh words such as melting point and gasification, Lao Wang was obviously stunned for a moment, but then he laughed happily again.
"Qin Feng, you said it very well, melting point! Gasification! These four words are enough to summarize the key points of the entire material melting! It seems that you are indeed a person who loves to think. Not only that, you can also learn from one example and apply it to other things!
If you summarize the four words, you won’t have to worry about teaching others in the future!”
Wang Blacksmith said, smiling all over his face.
Qin Feng accepted Lao Wang's admiration and praise without blushing, and said in his heart, Lao Wang, you may not have learned physics in middle school. Our physics teacher has said these things many times, and I have learned them.
Use it! Who made your scientific and technological level in another world be low?
Knowing the reason for the error in melting materials, Qin Feng started to improve it. There was no list of the melting points in another world. There was no way. Lao Qin had to ask Wang Blacksmith, and through his experience, he recorded these melting points on paper. At the same time,
By controlling the heat, the temperature of the furnace is controlled well.
After everything was prepared, Qin Feng began a new round of attempts.
He first prepared a portion of all the materials and then started adding materials to the stove. However, this time he learned to learn how to add a material, he first adjusted to the most appropriate melting point temperature, and after the melting is complete, he added it.
Next material.
In order to control the appropriate melting point and prevent the temperature from being too high, Qin Feng also changed the order of adding materials, and placed the groups of materials with the highest melting point to the end.
Because, if the material with a high melting point is added at the beginning, the temperature in the furnace will be very high and it will be difficult to lower it for a while. If the material with a low melting point is added, it will be easier to gasify to a greater or lesser extent.
Causes loss of materials.
The actual situation is indeed the case. Through Qin Feng's experiment, adding materials with high melting points first, not only did there be no errors, but other materials were not vaporized at all during the melting process and kept intact.
Wang Blacksmith was so stupid that he realized that melting point and gasification could be used like this. When he didn't know these two knowledge before, he was just trying to make iron according to the records of his predecessors and his own experience. Now,
Knowing the reason and knowing why, it will be much easier to melt the materials later.
After Qin Feng melted all the materials, he was very happy. Although he failed once, he found the problem, which was also a thing worth being happy about.
"Uncle, the materials have melted. Can you bring the mold of the longbow?"
"Well, okay, I don't know what type of mold you want, and what kind of sealing skills you choose?"
Wang Blacksmith asked Qin Feng about this. It was the first time Brother Feng built a fighting battle, and he didn't know what kind of mold to choose. As for the sealing skills, he was even more confused.
"Qin Feng, I have an ancestral mold here. Coincidentally, it is also a longbow, but I don't know if it should be used for you. It's not that the uncle is reluctant to let it go, but because this mold is the best in the heavenly ranks
The sealing mold, the sealing skills can be withstood by only the heavenly-level materials. You are creating a ground-level bow and arrow, so I am afraid that the condensation will fail!" After Wang Blacksmith said, he looked at the face of asking for advice.
Look at Qin Feng and wait for him to make his own decision.
After hearing this, Qin Feng gritted his teeth and failed. Anyway, it was the materials bought by Xiaoshuai, so he didn't feel sorry for wasting it. At worst, he could start over again. Anyway, at the point of melting the materials, I have found out my experience.
Thinking of this, Lao Qin pulled out his chest, "Uncle, just go and bring the mold, I want to see how awesome the Tianjie top-quality seal mold is!"
Wang Blacksmith nodded. Although he had no clue in his heart, Qin Feng had many tricks and might succeed. Even if the sealing skill is less powerful, as long as it can be used, it would be considered very powerful. After all, this
The sealing fighting technique in the mold is not simple, it is something that archers cannot seek - accumulate strength!
The so-called power accumulation means that when you pull the bow, you start the seal fighting technique to accumulate power. Then the arrow shot will add a certain external force to the elastic force. This external force is the power generated by the power accumulation skill. With this
External force, the speed and power of the arrow can be greatly improved. According to the top-grade Tianxing created by this mold, its power-causing skills can double the speed and power of the arrow!
Therefore, charging up power is already a very unparalleled seal fighting technique.
However, good things are difficult to perfect. Although the skill of power accumulation is powerful, it also has its disadvantages, that is, it requires a certain starting time every time it is used, which means it requires a process of power accumulation. This is a sneak attack
It's easy to use when it's done, but if it's in actual combat, it may take some time.
However, for Qin Feng, he learned archery to make an archer for the sake of Yin people, and the length of the startup time didn't matter to him.
It took less than a while for the blacksmith Wang to go and return.
He was holding a large jade box in his hand, carefully, as if holding a treasure, and walked into the operating room step by step very cautiously.
Qin Feng glanced at the jade box, thought in his heart, and guessed the importance of this thing to Wang Blacksmith.
"Uncle, is the mold inside?"
Wang Blacksmith nodded, placed the big jade box flat on the stone table, and then opened it carefully.
Qin Feng glanced at it and saw a long bow-type mold lying there quietly, which looked not much different from other molds, but Lao Qin knew that as the saying goes, the buns have folds all over the skin, but the inside is full of essence.
The same is true for this mold. Don’t be noticed, but once used, the fighting skills of the seal inside are definitely not simple.
"Qin Feng, the sealing magic technique attached to this mold is called power accumulation, it is like this..." Wang Blacksmith pointed to the longbow mold on the table and explained the power accumulation to Qin Feng.
Qin Feng was very excited after hearing this. Thinking of the power of the sealing magic technique, he kept his saliva. He only hoped that this magic technique that can be sealed by the top-quality combat soldiers in the heavenly level could be successfully transferred to the one he practiced.
In the fight against the ground level, even if the power is greatly reduced, then you are willing to do so!
The fighter at the Earth level itself is nothing great. The key is that this skill of charging power is really suitable for his use of bows and arrows. Other offensive sealing magic tricks are worthless in Lao Qin's eyes, because
No matter how powerful they are, they are not as good as forbidden spells and holy skills. They can only have some unexpected effects during fighting, and this accumulation of energy is different. They are definitely a powerful tool for sneak attacks!
"Uncle Wang, then what are we waiting for? Hurry up!" Qin Feng said, and used tools to lift up the furnace containing the liquid material. He couldn't wait to look at Wang Blacksmith, waiting for him to arrange the mold.
Seeing Qin Feng's anxious look, Lao Wang could only sigh helplessly, and prayed that the best sealing magic skill of the heavenly level could be successfully transferred to the ground level bow and arrow.
As soon as Wang Blacksmith laid out the ancestral longbow mold of their family, Qin Feng couldn't wait to pour the liquid material in.
Next, wait quietly for the temperature to cool down. In order to increase the success rate of condensation, this cooling is natural cooling and no cold water is used.
An hour later, although the surface of the mold was still red, Wang Blacksmith had already opened the mold.
Qin Feng looked at the longbow in the mold nervously and found that this longbow was a little different from other bows and arrows. The curvature seemed not very large, but the bow body was covered with strange patterns, like flowing clouds and water, making people
It looks very comfortable and does not look artificial at all.
"Uncle, has the shape condensed successfully?" Qin Feng asked carefully. Since it was the first time to build a fighting war, he was not very familiar with many aspects.
Although he passed the skills of beating the fighter, he still had not fully experienced the whole process.
Wang Blacksmith nodded, picked up the fighting soldier who had just condensed shape and looked at it, "The condensed shape is quite successful. I didn't see any cracks. When it is tempered, it will save a lot of effort!"
"Oh, has the seal magic technique been successful?" Qin Feng was most concerned about this. He didn't care about the level of fighting, even the yellow level.
Anyway, it's a bow, and there's no need to fight with others head-on. Although the lower level will make the bow unable to withstand greater elasticity, as long as there is power accumulation, he doesn't care about some flaws at all.
