Dongfang Bubai was stunned for a moment. Normally, the believers talked to her with great sincerity and fear, and they didn't even dare to lift their heads. Now, Song Qingshu gave her a...
But soon the anger in her heart was diluted by the surprise of Yu Jian's flight. She hung her whole body on Song Qingshu's body, with her pair of red phoenix eyes wide open, looking at the blue sky and white clouds like a newborn baby, and the rapidly retreating forest under her feet. Although her qinggong is unparalleled in the world, she can't fly freely in the sky like this.
"If you can take me to touch that piece of cloud, I don't care about your... behavior like that just now." Song Qingshu was trying to control the balance between the two when Dongfang Bubai's voice suddenly came from his ear. Looking up, she He was stretching out his slender white fingers and pointing at a white cloud not far away.
"What's so good about a mass of saturated water vapor..." Song Qingshu grumbled, and still manipulated the wooden sword to fly over there.
"I actually touched the cloud?" When Song Qingshu led her into the cloud, Dongfang Bubai seemed a little unbelievable, his eyes were white, and he reached out to touch it, but couldn't grab anything substantial. It just feels wet, especially illusory and impermanent. "I always thought that the clouds were soft to the touch, like cotton candy..." Thinking of the occasional reverie when looking up at the starry sky, Dongfang Bubai felt that he was so stupid at that time.
Suddenly, he felt a huge movement in his body, and Dongfang Bubai was so frightened that he hooked his hands around Song Qingshu's neck again: "What happened?"
Song Qingshu was dripping with cold sweat, gritted his teeth and said, "I'm afraid we're going to... crash the plane."
As soon as the words fell, the two fell straight down, Song Qingshu only felt that the true energy in his body was intermittent, and his body was also hot and cold, and he was terrified: Could it be that he has gone mad
Trying his best to control the speed of the descent, he tried his best to start gliding, and wobbled down hundreds of meters. Song Qingshu couldn't control it anymore, and the two fell directly to the ground.
Fortunately, after this period of time, Dongfang Bubai has recovered some of his internal strength, and he is not too high from the ground at this time. She sensed that Song Qingshu's internal energy was disordered, so she quickly let go of the hands that hooked his neck, and hugged him in the backhand. In my arms, I noticed that there was a pool of water below, and I used my internal strength to keep waving my palms towards the water surface, using the counter-shock force to counteract the falling force of the two of them.
However, the force of the two falling was more than a thousand catties. Feeling the shock force from the water surface, Dongfang Bubai spat out a few mouthfuls of blood, and with a bang, the two of them passed out just as they fell into the pool.
Song Qingshu woke up from a coma and found himself lying on the gravel stall. He heard the sound of water nearby and walked over following the sound. He saw Dongfang Bubai sitting on a rock by the bank, lifting the hem of his dress , a pair of crystal clear white legs soaked in water, there was a long and narrow opening on it, blood was constantly oozing, Dongfang Bubai was gently wiping and cleaning the wound around with a handkerchief.
The surface of the water was shimmering, Song Qingshu couldn't see clearly for a moment, he only felt that the skin on Dongfang Bubai's calf was more dazzling than the surface of the lake, it was rare to see Chapter 161 which sect Bernoulli belonged to
With her gentle and peaceful appearance now, she was afraid of disturbing her for a while.
Dongfang Bubai quickly noticed his arrival, and naturally put down the hem of his dress, and stood up: "Are you awake?"
"I'm really sorry that you have suffered such skin trauma." Song Qingshu glanced at her calf, apologetic.
"What is this little injury?" Dongfang Bubai shook his head indifferently, "You have given me enough surprises today, why don't you tell me how to fly with the sword." For a moment, Dongfang Bubai became a little crazy about the kind of leisurely way of walking against the wind when people soar in the sky.
"It's okay to tell you, but I'm afraid you won't understand." Song Qing expressed hesitation in his writing.
Dongfang Bubai's face turned cold when he heard the words: "In the world of martial arts talent, even if I don't rank first, I'm still in the top three. Do you think I can't understand?"
"Well then, listen carefully," Song Qingshu explained slowly with a playful look on his face, "When I carry you and fly on the wooden sword, the airflow in the air will bypass the wooden sword's lower surface, and The upper surface moves, the lower surface of the wooden sword is a plane, and the upper surface of the wooden sword is me and you. Just now, I deliberately controlled our bodies to maintain a streamlined angle with the sword body, so that the airflow passing through us is much faster than passing under the wooden sword. The surface speed, according to aerodynamics and Bernoulli's theorem, is also the fluid flowing through a certain surface. The faster the speed, the lower the pressure on the surface. Therefore, when the air flows through the lower surface of the wooden sword, it has a certain impact on the wooden sword. An upward supporting force, and this force is greater than the downward pressure on the wooden sword when the air flows through the upper surface of the wooden sword, it just offsets our own weight, so we can fly with the sword."
It turned out that when Song Qingshu was on Heimuya, when he flew over the lake, he realized that as long as the speed is enough, the stone can also float on the water surface, so he has been thinking hard about how to use the power of the water to truly cross the river with one reed.
Originally, his thinking had always been in the field of martial arts, and he hoped that he could fully understand the power of water. As a result, the more he thought about it, the more painful his head became. Until one day, a flash of light flashed in his mind, thinking of the principle of flying an airplane in his previous life. His company had done an aircraft project. When he was researching related materials, he did some research, and then he thought of using aerodynamics to solve the problem of Yujian's flight.
"Aerodynamics? Bernoulli's theorem?" Dongfang Bubai frowned, and asked in doubt, "Which sect's martial arts secret book is this, why have I never heard of it?"
"This?" Song Qingshu was stumped all of a sudden, so he had to say, "This is the secret book of the physics school in the far west, and no one in the Central Plains has heard of it."
"Physics school?" Dongfang Bubai fell into deep thought, suddenly raised his head and asked, "According to what you said, is it related to our speed that we can fly?"
"It's a pity that you don't study physics." Song Qingshu forgot to look at her in surprise, and nodded, "Yes, you can simply understand that Chapter 161 Which sect does Bernoulli belong to?"
The greater the speed, the greater the lift the air will give you. "
"Oh~" Dongfang Bubai's eyes were full of excitement, and he looked up at the sky, "Wouldn't it be that as long as my speed is high enough, the lift given to me by the air will be far greater than my own weight, so I can keep going up, so The legendary one who became immortal?"
"You think too much." As a modern person who knows that there is a cold and silent universe outside the earth, Song Qingshu doesn't quite understand why Dongfang Bubai is so interested in things like immortality, "When the speed of flight exceeds the speed of sound, , the air will become viscous, and the Reynolds number must be considered. It is not as simple as what I just said... Of course, if your speed can reach the first cosmic speed, it is not impossible to become a fairy and become a fairy, but it is only in flight On the way, you will be burned to ashes by the friction of the air."
Dongfang Bubai was confused when he heard that, and said angrily: "Then tell me directly, is it impossible to become a fairy and become a fairy?"
"It's really unlikely." Song Qingshu nodded, showing a regretful expression, "Uh, I think you might as well care about your drenched clothes instead of caring about such illusory things."
