Zhao Xin stepped forward, and before he could get his feet down, he was hugged by Wang Song and said loudly: "My little ancestor, what do you want to do?" ”

Wang Song's attention has always been on Zhao Xin, he has just recovered his safety, what does Zhao Xin want to do, he doesn't dare to let Zhao Xin set foot in the area of sulfuric acid. Pen, fun, and www.biquge.info

Zhao Xin tilted his head and looked at Wang Song, as if he was smiling, the reason why Wang Song and the others were afraid was that they still didn't understand. A large amount of concentrated sulfuric acid has been thrown in the circle, for such a long time, most of the strong oxidation of concentrated sulfuric acid has been reflected, and it has become something else, harmless substance.

Concentrated sulfuric acid has strong oxidation, water absorption, easy to absorb water, into dilute sulfuric acid, relative to concentrated sulfuric acid, dilute sulfuric acid will not be so harmful, with enough water to rinse, those have not had time to react with other substances of concentrated sulfuric acid, will eventually become dilute sulfuric acid, there is a certain corrosiveness, but does not have so much lethality.

"Fetch water!" Zhao Xin said calmly: "Then there is not much danger!" ”

?

Clean water washed the floor, a few small guys teamed up, lifted the water tank out, and then rinsed it with a basin, under the washing of water, the ground became turbid, blood, mud, and other things, were mixed together, quickly infiltrated, so that the battlefield became cleaner, found some stones to step on, Zhao Xin first set foot in this area, others followed.

Zhao Xin's eyes fell on the bow, which was a giant bow with a length of about 1.7 meters, which was similar to what he expected, only an ultra-long bow body could provide enough kinetic energy, otherwise the power of 15 stones would be too demanding for the material of the bow body.

The whole body of the moon bow is dark, even the bowstring is the same, Zhao Xin also thought that the bowstring will be eroded by concentrated sulfuric acid, if the bowstring is made of animal gelatin, it will definitely be like this, it seems that the bowstring is also iron, this is no problem, on the one hand, the concentrated sulfuric acid that falls on it will be less, on the other hand, it will not react too much, and it will not cause greater damage.

The bow body of the falling moon bow is made of meteoric iron, the bowstring was originally a composite material, which is a traditional gum, after entering the Wang family, the Wang family could not find a longer tendon when solving it, and used meteorite to solve it, but I didn't expect to have a miraculous effect, a longer bowstring, plus a coincidence, created the falling moon bow.

The labor-saving method of the moon bow is to use a pulley group, 2 sets of pulleys and a structure similar to an eccentric wheel, so that the bowstring is at least several times longer than before, and the bow body itself is much stronger than the general bow, and the bowstring after several times the length can only be artificial.

For the pulley block and the principle of labor-saving, I don't know it thoroughly, but in the end it can reduce the role of one-third, which is basically too different from the composite of later generations, the production is not fine, the layout is not very reasonable, a little more reasonable, you can save more force.

Zhao Xin understands this, Sun Ji and others don't quite understand, this is the difference in knowledge structure, Sun Ji They understand, it is based on the knowledge of this era, for example, how to use the power of the bow, how to aim, how to use feeling, to determine the location of the target, these are Zhao Xin can not accept.

What Zhao Xin knows, but some basic physics knowledge, the characteristics of the pulley group, in later generations, any one with a little knowledge of physics knows, the double side pulley block plus the eccentric wheel, reasonable combination, can save at least 80% of the force, this is the key to saving effort.

Zhao Xin didn't reach out to take it, compared to the flat ground, the strange bow body, it is easier to accumulate liquid, there is residual sulfuric acid on the bow, then it is a big joke, there are things around, people can find two long knives outside the sulfuric acid throwing area, these are iron tools, when there is no other suitable thing, iron clamping this thing is the most suitable.

Reluctantly clamped up, the operator was Sun Ji, Zhao Xin's strength couldn't lift this longbow at all, threw it into the water, stirred it with a long knife, changed it to 3 large tanks of water, took it out, there were some residues, and these residues didn't hurt the overall situation.

The sulfuric acid remaining on the moon bow is very little, after several times of water sparseness, there is not enough trouble, with a dry cloth, wipe it again, the moon bow is presented in front of everyone, the bow body is similar to the ordinary recurve bow, are two arc structure, the difference is in the position of the bow sheath, is hollowed out, two things similar to the wheel, fixed to that position, the bowstring is not fixed on the bow sheath, fixed in the wheel, through the pulley, after several crosses, formed a more unique, The appearance of intertwined bowstrings.

The concentrated sulfuric acid left traces on the moonfall bow, and on the bow, it was a dark surface with dense spots, which was the result of a large amount of concentrated sulfuric acid splashed on it. The reaction of concentrated sulfuric acid and iron is very fast, and it is blunted almost instantly, and it will not affect the entire bow body too much, which is equivalent to saying that the bow body has a little more different appearance, which seems to be a series of teardrops.

This bow is quite heavy, Zhao Xin's strength can't be lifted, so he directly asked Sun Ji to try, Sun Ji is not polite, he directly picked up the bow, felt the power of the falling moon bow, similar to the one he used before, and pulled it casually, it was a full moon, felt the power of the falling moon bow, found an iron arrow, opened the full bow, and shot out the iron arrow with extreme stretch.

The heavy iron arrow, with a whoosh, instantly crossed the space of less than 50 meters, hitting the trees not far away, and the iron arrow hit the colleague directly, directly penetrating the trees, and the power was very strong, exerting the power of a 15-stone strong bow.

In Sun Ji's eyes, among satisfied colleagues, he was slightly disappointed, this was not very in tune with his speed, and the rate of fire of the Falling Moon Bow was too slow. When he fought with Danmu before, he felt that Danmu's speed was not fast, and he thought that this was the characteristic of Danmu, everyone has their own characteristics, some people are good at speed, some people are good at range, some people are good at strength, Danmu may be one of them, not too sensitive to speed, and the actual speed is low.

After looking at the Falling Moon Bow, in order to pull away this 15-stone strong bow, he sacrificed his speed, and for a master like Sun Ji, his speed would also be doubled, and he would not be able to exert the huge power of the Lianzhu Arrow. Lianzhu arrows must be matched with a special bow, similar to the jasper bow, which is specially developed according to Sun Ji's strength, which is the most suitable.

Give Sun Ji time, he can cooperate with the moon bow to design a means of connecting arrows, after all, the rate of fire will be much faster than now, but the congenital deficiency, with the pearl arrow, it will also be a grade lower than the jasper bow, and the rate of fire will be greatly reduced.

"Your Highness, what are you doing!" Sun Ji suddenly said loudly.

Sun Ji pondered, Zhao Xin had already stepped forward and dismantled the Falling Moon Bow, not standardized, nor screwed, but with the help of a certain design, the two pulleys were stuck, as long as the position was found, the Falling Moon Bow could be removed, from a complete bow to a single part.

The solution of the moon bow with the help of the pulley group, it is estimated that it is also a coincidence countless times, perhaps, the designer has used part of the principle, but it is not too scientific, the pulley group is made irregular, there is no eccentric wheel, and the position of the arrow is not particularly accurate, so that the labor-saving is greatly reduced, but it is saved by about one-third, slightly adjusted, and some designs are added, it can save more than sixty percent of the effort.

Zhao Xin lit up the Falling Moon Bow, but did not light up the other parts, the material of the bow body and the bowstring, this is what he pays the most attention to, before I felt that it was the difference between the whole and the components, and the card level was completely different, he could only light up the whole, and could not be like other items, while lighting up the original, light up the raw materials.

Before, he estimated whether it would be a relationship of too short time, he didn't realize that he lit up the Falling Moon Bow, and unexpectedly lit up such a level 3 card, in front of the Falling Moon Bow, Zhao Xin also tried to scan the bow body of the Falling Moon Bow, but it still had no effect, obviously, it was not the reason.

The appearance of the sulfuric acid bottle made him understand that several simple low-level combinations can be combined into higher weapons, and if there is no pulley group, the Moon Bow is at most level 2, so the level of these different components should not be high.

However, because the level is already 2 levels higher than the current level, he is afraid that he will not show the separate parts, since there is no way to scan and separate them as a whole, he simply separates them, and when he observes, he has been looking at the position of the bayonet, and when he arrives at the position, he uses force to separate them into different parts.

This action made Sun Ji shout loudly, and then soon, he stopped talking, Zhao Xin did not destroy it indiscriminately, he seemed to be like a cow in cooking, disassembling the moon bow, and dividing the moon bow into different parts, bow body, bowstring, combined with some bayonets, two pulley sets, one by one.

At the same time as they separated, the card system flashed red, and as he had expected, these different components were lit up, and as he had expected, they were all a combination of level 1 and level 2.
