The unity of the human knife means that a knife and the knife fit, the knife is equivalent to a part of the body, and can be used freely under the control of the knife player, just like your hand.

Yanagi Kazuo clenched the wind forest volcano in his hand, raised the long knife high, and made a chopping posture, the momentum became more and more vigorous, and gradually entered the supreme state of the unity of human and knife. Guizang Takeo's face was grim, and he slashed 10,000 people horizontally, and the blade of the knife turned slightly, like an evil dragon that was about to go to sea at any time.

"Wind!" Liu Sheng and a man snorted softly, and the long knife turned into a flash of lightning and slashed down.

"Slash!" Guizang Takeo snorted coldly and met the slashing sword light. "Bell, bell, bell", more than a dozen dense double knife strikes sounded, and the tall trees in the dense forest were shaken by the scattered knives, and the fallen leaves fell colorfully.

Yanagi Kazuo took three steps back, and Fenglin Volcano put his backhand on his arm, breathing slightly.

Guizang Takeo took two steps back, and the blades of the ten thousand people shook slightly, pointing diagonally to the ground.

"Big brother, your knife is still very fast, and the speed of the knife is the fastest knife I have ever seen in my life, which is comparable to mine. It's just that your internal strength is inferior to mine. "Returning to Tibet, Takeo said solemnly.

"You can also take my whirlwind dragon slash and try it!" After returning to Tibet, Wuxiong said, 10,000 people were cut into the sheath, their right foot stepped on the ground, and their bodies were like spinning tops, spinning in place. Endless fallen leaves swirled around him, like a storm rushing straight into the sky.

Seeing this, Yanagi Kazu's face was solemn, "Steady as a mountain!" He snorted, his body was low, and his internal strength was constantly instilled into the wind forest volcano, as steady as a mountain.

"Slash!" Guizang Wuxiong burst into a shout, and 10,000 people slashed out of the sheath like lightning, and slashed diagonally at Yanagi and a man. Liu Sheng and a man lifted the wind forest Huashan with both hands, like lifting a 10,000-strong mountain, and met the 10,000-person behead.

With a loud bang, Yanagi and a man took three steps back in a row, his face turned red, and he forced down the backblood that was about to spurt out. Guizang Takeo took a step back, his face slightly pale.

"It's a wind forest volcano, it's the first time in the past ten years that someone can take my whirlwind dragon slash alive!" Guizang Wuxiong nodded, "Big brother, it seems that a comfortable life has not corrupted you, and you have been practicing sword skills diligently for the past twenty years." ”

"This is already your strongest defensive sword technique, right? I also have an even more powerful attack called 'Wind Blasting Thousand Slashes', so I'll show you some of it. Guizang Takeo sneered, held the long knife in both hands, and slowly raised it above the top, in the process of raising the long knife, his momentum continued to rise, and he had the power to destroy the world.

Yanagi Kazuo's expression darkened, and he thought to himself: "Fortunately, before I died, Yukiko's fate had been arranged. The rise and fall of the Yanagi family, there are still Senbei who can be entrusted with the follow-up. ”

He slowly closed his eyes, not looking at Guizang Wuxiong's mighty sword posture, and made a "quiet as a forest" sword posture, condensing all his skills and minds on the wind forest volcano knife. The wind forest volcano knife exuded a desperate momentum, Yanagi Kazuo knew that he couldn't accept this 'Explosive Wind Thousand Swords' knife technique, he was ready to use his "Hatred Like Fire" offensive knife technique, and died with Guizang Wuxiong.

Seeing that the two sides were about to fight to the death, Yanagi and a man were hanging by a thread. "Seniors are slow!" , A clear voice sounded from the edge of the dense forest, and Dugu Xiaotian, dressed in white, slowly walked over.

Under the bright moonlight, the calm and calm Dugu Xiaotian walked up to Yanagi Kazuo, he smiled at Guizang Wuxiong, and said easily: "I'll teach Dongying the first knife!" ”

When Guizang Wuxiong saw Dugu Xiaotian, his expression changed greatly, and he was shocked into a cold sweat. In this duel, he didn't dare to be negligent, and any wind and grass within a radius of twenty zhang in the dense forest was closely inducted by him. The fact that this person can lurk silently in front of him is simply appalling. If he had secretly made a move just now, his life would have been at risk.

Guizang Wuxiong glared at Dugu Xiaotian and did not answer. After a while, he slowly cut 10,000 people into the scabbard.

"The laughing man is powerful in the Central Plains, and it really deserves its name!" Guizang Takeo said in a deep voice in stiff Chinese: "In the duel just now, my internal strength has been consumed by nearly half, and it is not suitable to fight you again tonight, and I will learn your Pingtian Sword another day." ”

With that, he flashed into the dense forest, performed the ninja escape technique, and disappeared in an instant.

As soon as Guizang Takeo left, Yanagi Kazuo couldn't hold on any longer, and spurted out a mouthful of blood with a "wow", his face instantly turned a little pale, and his body was shaky.

Dugu Xiaotian hurriedly stepped forward to support Liu Sheng Yinan, Liu Sheng Yinan waved his hand and laughed, "My son-in-law has received it so well, and the return is really fast enough." ”

Yanagi took the two wound pills he was carrying, sat cross-legged on the ground and breathed for a long time, then stood up.

"Guizang Takeo is already the first swordsman in Dongying, fighting alone, Dongying is invincible!" He sighed softly.

Dugu Xiaotian and Yanagi Yinan returned to Yanagi's house, and it was close to the fourth watch. After escorting the head of the Liu Sheng family back to his house safely, Dugu Xiaotian returned to his courtyard, took out the captured short gun, and studied it.

In the early 15th century in Europe, someone invented a device that ignited with mechanical force, and it was soon used as a firing device on a gun, becoming a more advanced reed wheel gun than an arquebus. The principle of this lighter was similar to that of today's lighters, with an iron runner that was driven by a spring to rotate, causing the rough surface of the wheel to rub against a piece of pyrite and cause sparks.

The structure of the reed gun is more complex, compared with the general arquebus bolt with about 7 parts, the reed wheel gun bolt parts are more than 20, and the precision required for these parts is higher. In terms of principle, the spring principle of the reed wheel gun is actually very similar to the clockwork of the clockwork, so many gunsmiths of the reed wheel gun are made up of clockmakers.

Due to the need for superb technical production, the success rate of parts production is low, the production cost is high, and the service life is short, so the reed wheel gun is not popular among the general public, and is mostly popular among the European aristocracy and upper class, or for special military services such as cavalry.

It took only five years for the Portuguese craftsmen to produce only ten reed guns, and they could only be used nine times, and some of the parts on the guns would be scrapped. Since the reed wheel gun is not a weapon of the general public, the gunsmiths are naturally extremely clever in appearance, using various precious materials to carve exquisite and gorgeous patterns to match the noble status of the user.

Dugu Xiaotian studied the short gun for a long time, and tried to pull the trigger, he already had a basic understanding of the principle of the reed wheel short gun.

Dugu Xiaotian dismantled the twenty-five parts of the short spear one by one, weighed and rubbed each part in his hand for a moment, and then pondered.

The principle of this firearm is beyond the scope of Daming's current knowledge, and there is already a trace of the prototype of science and technology. Although the Ling Zhan soul in Dugu Xiaotian's body had not fully awakened, the scientific knowledge hidden in the depths of his memory gave him some special intuition about firearms.

Dugu Xiaotian took out the Pingtian Sword, took out six of the twenty-five parts of the gun body, and gently polished it on the Pingtian Sword, and after working for an hour, the polishing was completed. Dugu Xiaotian assembled the entire reed wheel gun again, and pulled the trigger a few times, satisfied.

He smiled slightly, then took out a sharp stone, carved a beautiful cherry blossom on the handle of the gun, and put away the short spear with a jade box in the house.
