The term ninja was only used in the Edo period of Japan, but its history dates back even further, dating back to the Asuka period in Japan, which is 13,400 years old! Ninja means 'man of covert action' and specializes in carrying out some secret espionage missions for the feudal aristocracy and ruling class. The skill that ninjas excel at is "ninjutsu".

"Ninjutsu", also known as "hidden arts", originated in China. It is said that Jiang Taigong Lu Wang, who was on the occasion of Yin Zhou, was the first to put forward the concept of ninjutsu and wrote it in the famous book "Liutao". Later, Sun Wu, Zhang Liang, Han Xin and others successively perfected the theory of ninjutsu, and then spread it to Japan, and ninjas appeared and developed in Japan with the spread of ninjutsu.

In ninjutsu, there are five ways of ninja: food, incense, medicine, qi, and body. Food, qualified ninjas have very strict weight standards, male ninjas cannot weigh more than sixty kilograms, and female ninjas cannot exceed forty kilograms. Because they have to haunt the branches and roofs lightly, and maintain full physical fitness at all times. Thirst-quenching pills made of ergot, plums, and rock sugar, and cold pills made of carrots, yams, and licorice are all commonly used foods. Incense, concealing one's identity is the most basic requirement of a ninja as a spy, and ninjas abstain from eating all foods that produce body odor, and bathing with special sand water is also to remove body odor. Medicine, every ninja is a skilled physician, as well as a poison maker and antidote, and they are good at using poisons and ecstasy. Qi, ninjas usually pay attention to self-cultivation, so that they can concentrate and be brave and brave in actual combat. Body, ninja focus on sitting breathing, acupuncture massage to tone muscles and joints in order to maintain the body's coordination and flexibility. Ninjutsu is an extremely complex skill, which includes skills such as fighting, creating chaos, and gathering intelligence in addition to the five ways of ninja.

Ninja weapons. Shuriken, Saling, Ninja Knife, Blow Arrow, Ninja Staff, Hand Armor Hook, and Water Spider are the seven most basic weapons of a ninja. "Shuriken" are darts, usually coated with poison at the tip of the blade. "Saling" is a kind of diamond-shaped weapon that is sprinkled behind you when you escape, and it is uneven. Anything that can stab your feet, such as natural stones, dried fruits, iron tools, etc., can be used. The "ninja knife" is usually attached to a rope about three meters long, which can be used as a stepping tool when climbing over the castle walls, and then used to retract the rope. The scabbard can be used as a ventor in the potential water when in danger. "Fukiya" is a poisonous needle, which is usually hidden in a flute, and sometimes it is necessary to disguise yourself as an entertainer during the journey, so ninjas must learn not only how to play the arrow, but also how to play the flute. A "ninja staff" is a cane with weapons such as chains, spears, and swords. The "hand armor hook" is a weapon that is worn on the hand, in a variety of ways, some are attached to the nails and some are worn on the back of the hand. It is up to the person concerned to choose which kind of kung fu he is good at. The "Water Spider" is a tool used to cross the river, and it can be stacked and hidden in a package.

In addition to these seven basic weapons, some ninjas are also good at using "sticks" and "bows and arrows". The "stick" is the most primitive revolutionary weapon of mankind. It is revolutionary because its performance is far superior to that of stones or roughly machined stone darts and stone guns. As soon as the stone was thrown, the weapon was lost in his hand. The sticks are easy to use, and can be used by picking a branch, which is good for melee combat, and can be thrown. In light of this, ninjas consider sticks to be one of the most important weapons. and developed a series of methods and techniques for the use of stick weapons, which became known as "stick art".

The rods used by ninjas are generally about five centimeters in diameter. It is about one and a half meters in length and is divided into two types: solid and hollow. The solid rod made of hardwood is powerful, and once hit by the solid rod, it is inevitable that the tendons will break and fracture, such as hitting the vital part, the danger is even greater. There are many materials used to make hollow rods. Generally the portions are lighter and seem less dangerous, but hollow rods are more sinister. Ordinary opponents would never have imagined that with a slight flick of the ninja's wrist, hidden weapons such as iron bullets, throwing knives, and short arrows hidden in the hollow hollow of the hollow stick would go straight to the throat or front of the opponent. Iron chains can also be hidden in the hollow rod. When facing the enemy, the iron chain scattered from the rod can bind the opponent by surprise. Ninja in order to facilitate stealth and carrying, the ninja knives used are very narrow, very disadvantageous when encountering long blades, in addition to the ninja knife because of its narrow body is not conducive to chopping, the main means of attack is stabbing, the limitation is very strong, compared to the "stick" advantage is greater, so there are few ninjas who are proficient in the "stick" technique, but once they meet it is a very terrible opponent!

"Bows and arrows" are also one of the weapons that ninjas are good at, and there are two types of bows used by ninjas: large bows and small bows. The large bow is used for long-range shots, and the small bow is used for close-range shots. In addition to shooting ordinary arrows, it can also be used to harass enemies, such as rockets, rattling arrows, and flowering arrows (arrows that can burst).

The biggest difference between ninjutsu and other martial arts schools is that it emphasizes spiritual cultivation, which should be based on physical training, and its entire training system is based on unimaginable spiritual cultivation. Because most of the tasks performed by ninjas are high-risk missions that never go back, and completing tasks alone in the enemy's lair has to overcome the troubles of death, loneliness, darkness, and even hunger, cold, injuries, and many other factors, so having strong mental strength is the real reason why ninjutsu is invincible. The training method of spiritual power is the secret of ninjutsu, and it is the practice of Dongmi! Eastern Esoteric and China's Tibetan Esoteric and Indian Esoteric Secrets, is a branch of Buddhism Tantra, Eastern Esoteric for the development of human mental power, has always had its own unique heritage, in the Esoteric world has been known for its significant speed, ninjas through the practice of Eastern Esoteric Secrets, temper their will, the spirit becomes incomparably pure and tenacious, the potential of the body is maximized, you can remove the confusion and fear of the mind, and concentrate on the battle. Tantra regards the Great Day as the master of all things, and strongly advocates the inheritance, mantra and mantra, and one of the main practices of the Eastern Tantric is the "Nine-Character Secret Seal": "Pro, Soldier, Fight, One, Both, Array, Column, In, Front" These nine words, the Ninja Sect has always attached great importance to these nine-character mantras!

As a descendant of a ninja family, once born, you must accept the cruel reality of fate - or become a ninja, or die, there is no other choice, the children of the ninja family, both male and female, must inherit the professional tradition of their ancestors, generally from the age of five to receive training, through long-term spiritual strength cultivation, so that they become a fearless and resolute warrior, not afraid of sacrifice, never give up until the mission is completed! In order to defeat them, in addition to having superb martial arts skills, it is more important to have a stronger belief than them! (To be continued......)
