Ao Shan thought for a while and said: "Master, when you were talking about 'Hidden Arrow' just now, the disciple suddenly thought of a hidden weapon that he had heard of before, which also hid a sharp sword in the barrel, which is very similar to the 'Hidden Arrow', this is what the people in the rivers and lakes call 'Blowing Arrow', the disciple is not very clear about what the hidden weapon of 'Blowing Arrow' is, can you tell me?" Ao Shan asked.

"'Blowing arrow' is a very influential hidden weapon on the rivers and lakes, before using the blowpipe, hide the small bamboo arrow in the blowpipe in advance, when you want to kill the enemy, one end of the blowpipe is aimed at the enemy, luck is enough, blow hard to the other end of the blowpipe, the bamboo arrow will shoot quickly from the end towards the enemy, the arrow is very small, the speed of shooting is very fast, it is difficult to guard against. The blowpipe of the 'blow arrow' is made of bamboo, and there are two kinds of long and short blowpipes, the long blowpipe is about fifteen inches long, and the short blowpipe is about seven and a half inches long, and the blowpipe is open at both ends, and the appearance of the blowpipe is generally very smooth, and some of the blowpipes are engraved with ornaments on the appearance. He Zihan said.

"The pipe of the 'blowing arrow' is a bit long, and if you want to blow the arrow out of the pipe, and the speed of shooting is very fast, does this require a strong internal force? Aoshan said.

"Of course, the use of 'blowing arrows' requires a strong internal force, and the stronger the internal force, the more powerful the blowing arrow, the more powerful it is, but the internal force is not the only condition for the use of 'blowing arrows'. It is also related to the structure of the blowpipe, the blowpipe must be well sealed, the air tightness will be good, and the blowpipe is absolutely not allowed to leak, otherwise, it will not be possible to blow the arrow out. When the blower uses the 'blow arrow', the reason why the arrow can be blown out is that when the blower sends air to the blowpipe, the air pressure in the blowpipe instantly increases, and the strong pressure pushes the arrow out of the blowpipe quickly. And the arrows went ahead. Some 'blow arrows' have a spiral texture engraved on the inner wall of the blowpipe. This can make the shot arrow rotate at high speed, and the arrow can eliminate the interference of wind in the rotation, and the shooting power is stronger. He Zihan carefully explained to Ao Shan the shooting principle of "blowing arrows", when Ao Shan asked about "blowing arrows". He Zihan thought of the bamboo on the "Cuizhu Mountain". She thought. Since there is a lot of bamboo on the mountain, in the future, it is possible to make zuò "blow arrows" and let some disciples practice "blow arrows". Enhance combat effectiveness.

"Master, the disciple thinks this 'blow arrow' is very interesting, it is very easy to carry, the arrow it uses is very small, and it looks very elegant on the whole, and it is quite suitable for the lady to use such a hidden weapon. Aoshan said.

"The arrows used in the 'blow arrow' are very small, that's right, but, in the hidden weapon family, there is a kind of smaller and more elegant than the 'blow arrow', and its lethality is not inferior to the 'blow arrow', it is a smaller hidden weapon - 'needle', 'needle' from the material used, there are steel needles, silver needles, bone needles, etc., from the perspective of use function, 'needle' as a hidden weapon, there are many types, for example, there are ' Plum blossom needle', because of the five steel needles in the root of the connection together and get the name, it is like a plum petal, when shooting to the enemy, there are a number of puncture points can hurt people, sometimes, 'plum blossom needle' can also be sprinkled on the ground, so that the enemy walks by to hurt the feet; The 'pointer' is often hidden in the gap between the fingers, and is used to stab the opponent's face and chest when fighting in close quarters; the 'needle' is hidden on the tip of the shoe and is used to kick the opponent's vital parts; in addition, there is also the 'embroidery needle', originally, this 'embroidery needle' is used by the woman in the boudoir to embroider, a steel needle, with a needle hole on it, used to thread, is used for embroidery, and later, this 'embroidery needle' was used by some women with martial arts as a hidden weapon, and became a very powerful hidden weapon. He Zihan carefully described the various "needles" used as hidden weapons, intending to make Ao Shan pay more attention.

"Master, the use of 'needle' as a hidden weapon, it is very suitable for women to use, especially the 'embroidery needle', which was originally used by women for embroidery, and now, it is used as a hidden weapon, especially with a woman's taste, usually, this 'embroidery needle' can be used for embroidery, and when it is forced to do so, it is used as a hidden weapon to deal with the enemy, which is very good, and the disciple likes it. Aoshan is more interested in the "embroidery needle".

He Zihan heard it from Ao Shan's words, Ao Shan prefers the secret weapon of "embroidery needle", she decided to let Ao Shan practice "embroidery needle", in the future, she can feed the "embroidery needle" with poison, so that the "embroidery needle", the secret weapon used by women, is more lethal.

"You are more interested in the 'embroidery needle' Master knows it in his heart, later, you are familiar with all kinds of 'needles' used as hidden weapons, especially to understand the characteristics of 'embroidery needles', if you think that 'embroidery needles' are the most convenient to use, in the future, you will focus on practicing 'embroidery needles', if you practice the "embroidery needles" proficiently, it is also very lethal. Of course, for other hidden weapons, you also need to understand, there are many types of hidden weapons, of course, it is impossible to understand them all, but, for the general situation of the hidden weapon, you still need to understand, the above is to classify the hidden weapon by the distance between the hidden weapon and the user, in fact, some people divide the hidden weapon into four categories: hand throwing, rope strike, machine shooting, medicine spray, for example, the hidden weapon of the hand throwing class has javelin, dart, throwing arrow, flying fork, flying thorn, flying sword, flying knife, dart knife, flying locust stone, jujube core arrow, Ruyi bead, Qiankun circle, iron mandarin duck, Plum blossom needles, etc.; rope-striking hidden weapons include rope darts, flying claws, soft whips, brocade lassoes, meteor hammers, wolf's tooth hammers, dragon whisker hooks, iron lotus, etc.; machine-shot hidden weapons include sleeve arrows, slingshots, crossbow arrows, back crossbows, stepping //crossbows, thunder drills, etc.; medicine spraying hidden weapons have sleeve cannons, spray cans, bird's beak guns, etc., among them, some hidden weapons are quite popular in the rivers and lakes, such as flying claws, soft whips, finger swords, steel rings, ruyi beads, brocade lasso, iron lotus, three-edged thorns, iron thistles, cross darts, etc. He Zihan saw that Ao Shan had a martial arts foundation and a flexible mind, and she really wanted to train Ao Shan to become a master of using hidden weapons, so she was very careful about Ao Shan's secret weapons, she knew. Let Ao Shan know more about hidden weapons, so that Ao Shan is more familiar with and more interested in various hidden weapons, which will be of great help to Ao Shan to improve the skills of hidden weapons in the future.

"Master, you have talked about so many secret weapons, it is already difficult to memorize their names, and it is even more difficult to understand them in depth, and it will take a long time to understand. Aoshan said.

"You don't necessarily remember all the names of the various hidden weapons, and you don't necessarily have to know them all thoroughly. But. It's still necessary to know about them, and later, when you fight the enemy, when the enemy uses a hidden weapon. You'll have an idea of the hidden weapons your enemies are using. It will be possible to fight the enemy more actively. Knowing oneself and knowing one's opponent is the only way to win. He Zihan said.

"The disciple understood, learn the secret weapon. Just like learning other skills, it is necessary to understand all kinds of knowledge related to this ability, so that you can learn this ability better, and the disciples will carefully understand the secret weapon. Aoshan said.

"You are not wrong, to learn the ability to first master the relevant broad knowledge, and then to learn more specialized, Bo and professional is the corresponding idea, only on the basis of 'Bo' can be more 'specialized', and only with more 'specialized' knowledge, 'Bo' can be understood more thoroughly, in fact, the hidden weapon is very much, and as long as some elements are added on the basis of the original hidden weapon, it has become a new, more powerful hidden weapon, for example, when the hidden weapon is fed with poison, it becomes a poisonous hidden weapon, known as 'poisonous weapon'. He Zihan said.

"It's powerful enough for a hidden weapon to take advantage of people and hurt people unexpectedly, if you feed poison on the hidden weapon, it will be even more terrifying, and the lethality of this 'poisonous weapon' must be very good!" Ao Shan said.

"Yes, the poisonous hidden weapon is very terrible, the legend, there is a very terrible 'poisonous weapon' on the rivers and lakes, called the 'Five Poison Plum Blossom Needle', it is said that when refining the 'Five Poison Plum Blossom Needle', the needle is placed on a smokeless charcoal fire and roasted, and the whole needle is roasted red, and then, one end of the needle, about three points in length, is immersed in the liquid medicine and quenched, and then, it is burned red and then quenched, at least seven times repeatedly quenched, in order to make the 'Five Poison Plum Blossom Needle'. It is worth noting that the venom of the soaked needle is prepared with five kinds of poisonous small animals, and its preparation method is: take a toad, three red centipedes, a red snake, five green spiders, and a flower gecko, at noon on the fifth day of the fifth month of May, take about a pound of cattle urine, put it into the clay pot to soak, after the clay pot is sealed, bury it in the soil, and then take it out after forty-nine days, at this time, the needle is fed to the medicine is completed. The 'Five Poisons Plum Blossom Needle' is very toxic, and when it is pierced into the human body, the person will faint immediately, and if the healing time is missed, he will soon die. It is said that this 'five poisonous plum blossom needle' also has a secret antidote, the recipe of the antidote is: take more than two taels of crabs in the mountain stream, put them in the earthen pot and fry them, and then, add a pound of rice wine to the fried crabs, put them in the ceramic jar to seal and soak, take them out after 49 days, and the antidote will be made zuò. In fact, the poison and antidote prescription fed by the 'Five Poison Plum Blossom Needle' are all heard from legends, and the master did not verify them, I don't know what the specific effect is, the master told you about the 'Five Poisons Plum Blossom Needle', just to let you have a specific impression of the hidden weapon that feeds the poison. He Zihan said.

"The example given by the master is very specific and vivid, and the disciples can learn a lot about the knowledge of the 'poison weapon', and know that the 'poison weapon' is very particular about soaking poison, and the toxicity of the 'poison weapon' is directly related to what medicine is soaked and how it is soaked, so the power of the 'poison weapon' is actually directly related to the development of the poison. Aoshan said.

"Haha, I didn't expect it, you just followed your Uncle Lin to learn pharmacology, and you know how to use pharmacology to explain 'poison weapons', your understanding is very good, and you will definitely be able to combine the use of hidden weapons and drugs in the future, maybe you will have a new creation of 'poison weapons'. He Zihan said happily.

"Master is afraid that the disciple is high, the disciple just followed you and Uncle Lin to learn a little knowledge, in the future I don't know if I can really learn the ability well, the master carefully taught the disciple to learn light skills, the disciple has just started, and it will take a long time to practice to master the essentials; When the 'embroidery needle', the disciple thinks that it is more suitable for the disciple to use, and the disciple is more interested in the 'embroidery needle', so if the master allows it, ask the master to teach the disciple to practice the 'embroidery needle', and the disciple will definitely follow the master to study and practice diligently very seriously, and must learn the secret weapon of 'embroidery needle' well. Aoshan boldly made her own request to her master.

"When Master talked about 'Embroidery Needle' just now, you were very excited, Master actually knew that you had a choice, and Master also felt that 'Embroidery Needle' was very suitable for you, but you must know that although 'Embroidery Needle' is small, you still need to learn a lot of skills to use it as a secret weapon, and at the same time, you need to practice internal skills, you have to learn a lot of content, you can't give up halfway. He Zihan said.

"Master rest assured, no matter how difficult it is to learn the secret weapon, the disciple will definitely persevere, the secret weapon will be a difficult hurdle for the disciple to concentrate on overcoming in the future, I hope that in the future, the disciple can use the skilled secret weapon to do a little bit for the master to do great things. Aoshan said confidently. (To be continued......)
