The straight line between the two points is the shortest, and the junior high school teacher teaches it.

But the dragon scale special combat knife that Long Fei threw out did not go in a straight line, not because Long Fei didn't understand science, but because he had been practicing the whirling knife technique.

After the knife is thrown, it will rotate violently like the propeller of a helicopter, and the rotating knife stirs the air, constantly changing the trajectory of the knife, and finally makes the movement trajectory of the knife in the air become an arc.

And when the arc of this arc reaches a certain level, the trajectory of the flying knife is a circle, and when the time comes, the flying knife can return to Long Fei's hands.

The trajectory of the flying knife has been changed from a straight line to a curve, although the trajectory has been lengthened, but because the direction of the blow is more confusing, it is more difficult to prevent!

If the knife flies in the air and does not hit the object, Long Fei is sure that the knife will fly back into his hands, but if the knife hits a person or object, because the knife is stressed again, the trajectory will change immediately, and it can no longer fly back into Long Fei's hands.

In order to overcome this difficulty, Long Fei can only make the throwing knife he throws more fierce and spin faster, and with the powerful force and the unstoppable sharpness of the dragon scale special combat knife, he can ignore the force of the flying knife after hitting the object, in order to succeed!

Although Long Fei threw out the flying knife in a straight line more accurately and ruthlessly, in order to completely practice the whirlwind knife technique, he used this whirlwind technique every time he made a knife!

This time is no exception!

As soon as Long Fei slashed out, he stared at the trajectory of the flying knife with wide eyes, hoping that the flying knife would hit the target, and then flew back to his hands unharmed.

The dragon scale special battle knife quickly drew a white line in the air, and quickly flew towards the big mouth!

Long Fei saw that the dragon scale special combat knife instantly swept over the right hand of the big mouth holding the gun, and made a slight click!

I saw that after the dragon scale hit Big Mouth's right hand, it did not land immediately, but continued to fly forward, drawing another arc in the air!

However, Long Fei looked at the flying knife that was still flying in the air, but he sighed in his heart: "Alas! Brother's whirling knife technique is still almost hot!"

At the moment when the flying knife hit the gun in Dazui's hand, Long Fei saw that the blade of the flying knife trembled suddenly, so he judged that he had failed again this time.

As Long Fei expected, after the dragon scale swept away the gun in Dazui's hand, he only flew forward about a meter forward, and fell to the ground with a bang.

When Long Fei appeared, he didn't roar, he didn't scream, he rushed onto the van with an arrow, and the cold was a knife, so it wasn't until the dragon scale special combat knife fell to the ground that everyone on the field suddenly realized that a third-party force had joined the battle group!

The first thing to reflect was the big mouth, and this guy suddenly "snorted" is throat, and then jumped straight up on the spot holding his right hand! Blood fell to the ground like beads of broken threads through his fingers.

While the dragon scale combat knife slashed the gun in his hand, it also cut off the index finger of his right hand that was placed on the trigger guard. Wan Qing's subordinates had another nine-fingered beggar.

"Long Fei?!" Big Mouth and Long Nose and the others exclaimed in unison!

Long Fei has become Wan Qing's number one enemy, so there is no one in Wan Qing's core personnel who does not know Long Fei.

The moment Big Mouth and Long Nose and the others saw Long Fei, they knew that the mission of their trip was that they were going to complete it! Not to mention completing the task, it was a question of whether they could go back or not! Long Fei was not a good talker.

Long Fei's sudden appearance frightened Dazui and the others, but Long Duoduo was so excited that she didn't even have time to pick up the soft whip on the ground, she ran to Long Fei in a few arrow steps, and then jumped suddenly, and pounced on Long Fei's body, like a little child, holding his brother's neck with both hands, and a pair of long legs tightly clamped around his brother's waist!

"Brother, why are you here?!" Long Duoduo said excitedly.

She has been a follower behind her brother since she was a child, she follows her brother wherever he goes, and prefers to be tired of being in her brother's arms, and her feelings for her brother Long Fei are even more than her feelings for her father. Although he is older now, his attachment to his brother has not weakened at all.

"Oh, my own sister, slow down! My brother's small waist can't stand it!" Long Fei said that he couldn't stand it, but his face was full of smiles, he had loved his sister very much since he was a child, and every time he saw her, he felt a sense of pride in being an older brother.

"Come down, come down, she's such a big girl, why are you still so naughty? Long Fei said with a smile.

"Phew, I'm not afraid of their jokes! You're my brother, not my boyfriend, what are you afraid of?" Long Duoduo said with a smile on his eyebrows, and jumped off his brother's body.

"What you say is really fresh, so you will never let your boyfriend hug you in the future?" Long Fei said as he looked at his sister.

Long Duoduo's face turned red and said, "Brother, you are making fun of people again." I don't want to find a boyfriend! I want to find someone like my brother!"

"Hehe, aren't you looking for a boyfriend? I heard that a few days ago, it seems that a boy came downstairs to your dormitory to light candles, set roses, and say loudly that he loves you!" Long Fei remembered what the dormitory administrator's aunt had told him.

"Don't mention him, science student, that's terrible. Long Duoduo said disdainfully, art girls seem to have some natural dislikes for science men.

"My brother is also a science student. Long Fei said helplessly.

"Brother is different from them!" Long Duoduo said with a smile.

The big-mouthed group of people looked at Long Fei and Long Duoduo, who were talking about brother and sister love, and couldn't help but be very hurt. Are we human beings, so why do you ignore us? Do you let us go, or do you let us go?

One dragon duoduo can beat them to the ground, and they are all injured, and now there are many awesome and shining dragons, and they don't even have the courage to escape!

In the end, a little brother standing next to Big Mouth cautiously asked Big Mouth: "Brother Big Mouth, what should we do????????"

As he spoke, the guy stretched out his right index and middle fingers in a walking position.

"Go, be quiet, don't alarm those two guys who are already in the play. Big Mouth whispered. Although he also knew that Long Fei couldn't just let them escape like this, he still wanted to make a try.

A group of people crept towards the van, their eyes staring closely at Long Fei, who was chatting with his sister, for fear that Long Fei would suddenly let out a loud shout and let them stop!

At this time, the big mouth and long nose really hoped that Long Fei would treat them as a few annoying flies and let them leave freely.

Big Mouth and Long Nose really couldn't imagine what Long Fei would do to them if they fell into Long Fei's hands! But one thing they could be sure of was that Long Fei would never let them have a good time! The white eyebrows and black mole were their role models!

Wan Qing's four King Kongs, the most awesome black mole is still lying in the hospital, it is said that Long Fei's needle in his carotid sinus triangle was too deep, the black mole was too seriously injured, and he couldn't be discharged from the hospital in half a month. And Bai Mei, like Wan Qing, was poisoned by Long Fei, and if he didn't get Long Fei's antidote after a month, he would become a mollusk.

Not to mention them, even Wan Qing, a god-like man in their hearts, has never received any benefits from Long Fei since he chose to be the enemy of Long Fei!

All of this made Long Fei leave a huge shadow area in their hearts.

A group of guys prayed in their hearts that Long Fei would not leave them behind, and slowly rubbed in the direction of the van, all believing that as long as they got in the car, their escape would be half the success.

These people's prayers seemed to have been effective, until Dazui and everyone got into the car, and Long Fei didn't even stop them! It seems that Long Fei really doesn't care about dealing with them.

"Drive, let's go!" shouted excitedly at the little brother who was driving in front of him, wishing that his little universe would explode and make the car fly!

"Sting!"

The little brother who was driving the car hung up the reverse gear, released the clutch, and kicked the accelerator to the end, and the car suddenly roared and reversed out of the alley.

Everyone in the car had ecstatic looks on their faces, thinking that this time they could escape!

However, at this moment, I saw Long Fei, who was chatting with his sister, suddenly arrived in front of the dragon scale special combat knife on the ground with an arrow step, and then used his left foot as a support point, and his right leg flicked suddenly, and his toe suddenly kicked on the handle of the dragon scale!

Like a cannonball, the dragon scale knife flew towards the tires of the van with a swoop!

Long Fei's feet didn't know how to play the whirling knife technique, he chose the direct shooting method, and the dragon scale special combat knife stirred up the air and made a sharp whistling sound, which instantly pierced the tires of the van!

"Bang!" the van burst a tire instantly!

The van that reversed quickly suddenly burst its tires and overturned in an instant, splashing a puff of smoke and dust, and a bunch of guys inside were even hit on the head and bleeding!

A group of guys scolded their mothers in their hearts, and said in their hearts: "Long Fei, you want us to stay, why didn't you say it earlier? We can't listen to you? Why are you playing with us like this? This is not a monkey, you are going to kill our people in the city!"

The injury to the long nose was relatively light, he struggled to open the car door above, and then stepped to get out of the car, but as soon as this guy showed up, he saw that Long Fei had already walked in front of him, and said to him with a smile: "What?

"I don't want to go, I still stay in it for the rest of my life!" Long Nose scolded in his heart, this guy scolded in his heart, but said with a flattering smile on his face: "Don't go, don't go!"

"Why don't you go, why don't you open the car door?" Long Fei asked again, the smile on his face was even thicker, but this thick smile was more terrifying than a frost in the eyes of the long nose.

Long Nose scolded again in his heart, but the smile on his face became stronger, and he said repeatedly: "Oh, the air inside is not good, I want to come out to breathe." Ah, breathe, breathe I'll go in again. ”

As he spoke, the guy actually shrank back into the van.

"Oh, the air is bad, the air is bad, I'll spice you up. ”

As he spoke, Long Fei took out half a stick of sandalwood from his body, then lit it with a lighter, and then asked, "Do you know what this thing is?"
