In his previous life, when he was Zhang Yu, he was particularly envious of those so-called travel friends, but unfortunately he had no time or spare money to go, struggling at the bottom of the society, he repeated the same life every day, just like most white-collar workers and unemployed people in modern metropolises.

But now Inuyasha has a lot of time and energy to explore the unpolluted nature of ancient times, and at the same time, he is also expanding his horizons and perfecting his abilities. Because he can't enter the human village, Inuyasha lives alone in the mountains, but fortunately, he has become accustomed to loneliness, and occasionally fighting with those youkai who are attracted by his own smell has also become his pastime.

In this way, he stopped and practiced while fighting, and a hundred years passed quickly, and Inuyasha grew into a thirteen or fourteen-year-old boy. In this lonely hundred-year journey, Inuyasha has completely forgotten the Zhang Yu of his previous life, not only those modern lives, but even Chinese, but also forgotten because he has not told for a hundred years, except for those cultivation methods that have been perfected in his mind can also prove that Inuyasha is different, he has completely become a half-demon who lives in the anime world.

Inuyasha's biggest gain in this hundred years is combat experience and experience, far longer than human life has made him visit almost the whole of Japan, among them, he has naturally encountered a lot of powerful monsters, also escaped, and was seriously injured, the most dangerous one was at the time of the new moon was targeted by a top monster close to the big monster, although he has a lot of spiritual power, but even if he is a half-demon, he may not be able to beat the eagle-shaped monster, let alone only a quarter of his original strength when he is a human, Therefore, although he was seriously injured in the escape and survived until sunrise, he finally burst out all his demon power and barely escaped the pursuit of the monster and burrowed deep into the ground.

But fortunately, this serious injury happened to be in the evolution stage of Inuyasha, just like the dog shedding, Inuyasha also ushered in the first evolution of leaving the dog monster, and at the same time, Inuyasha also used the spiritual power accumulated by the person for a hundred years, and broke the bottleneck that hindered his demon power storage in one fell swoop, and increased the amount of five hundred demon power to one thousand, which doubled, but even so, he raised it underground for a full ten years before he recovered all his injuries and stabilized his strength.

Ten years later, Inuyasha once again found the hawk monster that had seriously injured him, and fought fiercely with it for three days and three nights, and mastered all the moves and mysteries that he had compiled for ten years before killing it. The flesh and blood of youkai with good bloodlines is also a great supplement for youkai, which is why Inuyasha was attacked by so many low-level youkai, so after Inuyasha killed the hawk monster, he roasted it whole and ate it, and some of the youkai who smelled the smell were also eradicated by him one by one.

However, this is Inuyasha also feels that his means of attack are still too single, and as a half-demon, he can't become a giant dog like his father and Sesshomaru, so after thinking about it for a while, he thought of his father, and the strength of the Fighting Tooth King who has become a * humanoid is not much weaker than that of a dog, because he uses a knife to fight in a humanoid form. After thinking about it for a while, Inuyasha decided to build a knife of his own.

The material is just using his own teeth, although he doesn't know how to forge it, but from the knowledge of memory, he seems to see the way to use demonic power or spiritual power to refine materials, and then turn them into his own natal weapons.

However, he still underestimated the difficulty of building a good knife, so as a last resort, Inuyasha had to find the more famous knives in this world, and at the same time add his own teeth and then use his pure demonic power to exercise.

However, Inuyasha's luck is indeed good, and it took him ten years to find dozens of famous knives, including demon knives that were infected with demonic qi by killing countless monsters, as well as death knives that absorbed human blood and mutated, and even purified knives that were specially used to eliminate demons.

Among them, Inuyasha also encountered swordsmen unique to ancient Japan in the process of collecting knives, and their swordsmanship can even kill high-level youkai, and Inuyasha also disguised himself as a human in order to learn their swordsmanship, or hid in the shadows to learn their swordsmanship. There were a few times when a few swordsmen encountered a powerful youkai and were about to be killed, they stepped forward to kill the youkai, and from this they met a few human swordsman friends, of course, only on the Cheng dù they knew, because after feeling that they could no longer learn from the swordsman, Inuyasha would leave and choose the next target.

In this way, Inuyasha learned from the Lord of the Rings, found a crater, wrapped his demonic power in the famous knife he had collected in the past ten years and threw it into the magma, with the help of the vitality of the volcano, and at the same time threw his own teeth, and after forging for seven hundred and forty-nine days, Inuyasha's exhausted knife was finally baked.

A silver-white Tang knife, the shape is somewhat similar to the knife of the hero in the Chaos Legion, but because there are too many materials added, and Inuyasha also likes Chinese swords, so the blade is much longer, two meters long, you can slash with one hand, you can also chop with both hands, and the blade is extremely sharp, the blade is strong, because it is contaminated with monsters and human blood and the power of purification, it can corrode the wounds caused, and the sword qi emitted with a light wave is enough to kill hundreds of monsters in an instant.

Of course, the most important thing is that this knife is connected to Inuyasha's mind, so as the strength and number of youkai it kills, as well as the strength of Inuyasha's strength increases, this knife will slowly grow. And the name Inuyasha had already been thought of, "Traces of the waning moon!" "In memory of the sixteenth night of his mother, for the night after the fifteenth night of the full moon is the sixteenth night, the month of the gap, from perfection to incompleteness. For this reason, Sixteen Nights is given a special meaning in nature, symbolizing the decline of feelings from thick to light, and after things reach their peak

The next step is to familiarize yourself with the power of this knife and create the mystery of this knife at the same time.

With human strength, without using demonic power, Inuyasha walked as a swordsman in the human world for twenty years, with a cloak on the outside of the fire rat robe and a traveler's straw hat on his head, Inuyasha did not approach the shrines and places guarded by shrine mages, but only slew the man-eating yokai and robbing bandits and robbers in the remote mountain villages and on the roads outside.

In the first hundred years, Inuyasha had already killed people, a group of robbers ransacked a village that Inuyasha passed by, and killed all the people inside, and in the face of these ferocious humans, Inuyasha finally went on a killing spree, stained with human blood for the first time.

However, Inuyasha's human cultivation journey has created a great reputation for himself - the Silver Moon Sword Master.

In addition to the fact that the knife in Inuyasha's hand is called the mark of the waning moon, the sword energy it emits is like a silver moonlight, and the sword master refers to Inuyasha's superb swordsmanship, and even those high-level youkai can be killed lightly, and the top youkai were led to a place where no one was to solve it, because if you don't use demon power, Inuyasha doesn't have the certainty of defeating the top youkai. The peculiar talent unique to top youkai cannot be underestimated even by the big youkai, and Inuyasha has not yet been arrogant enough to defeat the big youkai.

However, the lifespan of human beings is limited, and if the Silver Moon Sword Master stays in the human world for too long, it will arouse the suspicion of humans, and twenty years is enough time for Inuyasha to perfect his sword skills and mysteries.

The four moves combined with the mystery of the Trace of the Waning Moon gave Inuyasha the confidence to challenge the Great Youkai.

Moonlight - arc-shaped sword qi, the origin of the Silver Moon Sword Saint, can be issued at will, the number varies, up to ten in an instant, a single group attack can be, the power is amazing, one can kill hundreds of monsters.

Fenghua - Turning the sword into silk, the sword body is placed obliquely, and it rotates at a very fast speed, completely shattering everything around it, including the ground under its feet, ignoring the mystery of group attack and defense of the enemy and us, ranging from Inuyasha as the center, and can reach as far as a hundred meters away.

Dark Night-The power of destruction and purification that uses demonic energy to draw out the traces of the waning moon can only be condensed in the body of the sword, indestructible, and indestructible.

Chaotianque - the current strongest mystery, only half completed, but the power has far surpassed the other three arcane meanings, all the power combined with Inuyasha's swordsmanship to slash at will, can cut the white clouds in the sky in two.
