It’s no wonder that Sun Wu and Confucius are expecting so much, because they can’t fly!
Yes, Sun Wu, Confucius and other great masters who are called saints and ancestors, even though they have the shocking power to destroy mountains and seas, they can't fly.
To be precise, it is impossible to fly long distances and for long periods of time!
Of course, there is no problem with short-distance low-altitude flight, but the actual effect is equivalent to the Hulk's big jump, which is just a flying brick with great strength.
Feeling the eager eyes of everyone, Wang Liangyu quickly shook his head and explained: "Don't have too much hope, I'm just thinking wildly!"
"Tell me more specifically!" Sun Wu raised his hand to stop Wang Liangyu from talking and urged him repeatedly, "I know you have ideas, tell us!"
Wang Liangyu heard this, thought about it for a long time, and then told everyone about aerodynamics in a way they could understand:
"You have all seen birds flying, right?"
Hearing Wang Liangyu's question, not to mention the reactions of Sun Wu and others, even the white ape became a little angry. He stabbed Wang Liangyu with a bamboo stick, bared his teeth and yelled, as if he was teaching Wang Liangyu a lesson.
Wang Liangyu laughed sarcastically and continued: "The reason why birds can fly mainly relies on two forces, lift and thrust!"
In fact, the flight process of birds is very complicated, and it also involves gravity and resistance. Both of these are a bit troublesome to explain, so Wang Liangyu simply omitted them without affecting the explanation.
"What is lift? When a bird flaps its wings, the air will flow faster on the upper surface of the wings, which will reduce the air pressure above and make the bird rise upward." Wang Liangyu said as he broke off a piece of wood.
, and then cut it into the shape of an airplane wing with the body-penetrating true energy, and then said to Xu Yuan and Yuan He, "Master Xu, Yuan He, you cast wind spells on the top and bottom of the wooden board respectively."
Wang Liangyu grabbed the wooden board, faced Xu Yuan and Yuan He, and taught him seriously: "Master Xu, your wind spell is a little faster, Yuan He, your wind spell is a little slower." After a pause, he added, "
Blow flat and slightly away from the wood chips!"
Xu Yuan and Yuan He looked at each other and followed Wang Liangyu's instructions to cast the wind spell.
Sun Wu and others, not knowing what Wang Liangyu was doing, stared at them curiously with their eyes wide open, completely ignoring the competition on the stage one after another.
Wang Liangyu also paid no attention to the fighting on the platform. He held the board with one hand and carefully felt the wind on the board.
As the wind continued to increase, at a certain moment, Wang Liangyu felt that the wooden board in his hand had lost its weight.
In an instant, Wang Liangyu let go of his hand.
The next moment, exclamations came one after another, accompanied by waves of gasps.
Everyone present is a big boss, and they can confirm that Xu Yuan and Yuan He's wind spell is still some distance away from the wood chip, and does not really act on the wood chip, so this piece of wood suspended out of thin air is not blessed by any extraordinary power!
This is a strong and exciting impact to a group of literary figures who have not been baptized by science!
Confucius twirled his white tiger beard, barely maintaining the surface calm, and carefully observed the wood piece for a long time. He turned to Wang Liangyu and said, "Is it flying because of this shape?"
After hearing what Confucius said, Wang Liangyu couldn't help but give him a thumbs up and praised: "Master is indeed a master, he can see the key at a glance!" Then he continued, "As I just said, but objects
The air flow speeds up and down are different. The faster the flow speed, the lower the air pressure. This creates a small pressure difference between the top and bottom of the wood chips, and the wood chips are suspended!"
With that said, Wang Liangyu signaled Xu Yuan and Yuan He to stop the wind curse.
When the wind curse stopped, the wood chips instantly fell down.
Wang Liangyu picked it up, showed the arc to everyone, and said with a smile: "I wonder if you have noticed that when a bird flies, its wings show such an arc shape?"
Everyone was stunned when they heard this, recalled it carefully, and nodded in agreement.
"Why is it such a curvature?" Wang Liangyu asked, and then he pinched one side of the wood piece. The wood piece hung down under the action of gravity, and then said to Yuan He, "Yuan He, cast a wind spell on it.
,Follow the direction of my arm!”
Yuan He didn't understand what it meant, but he still followed Wang Liangyu's instructions and blew the wind spell on the wood pieces.
Under the influence of the wind force of the wind spell, the originally drooping wood pieces actually floated up little by little, and soon they were suspended sideways in the air.
"The top of the wood chip is slightly arched. When the wind blows, the flow velocity above will be faster than the flow below. A small pressure difference will be formed between the top and bottom of the wood chip. The wood chip will receive an upward lift and will naturally float!"
When the wood chips were suspended, Wang Liangyu's voice sounded at the right time, briefly introducing the scientific principles to everyone.
Listening to Wang Liangyu's words, Bai Yuan couldn't help but stretch out his hand and feel the wind speed up and down the wood chips.
Because of the white ape's actions, the upper and lower wind speeds of the wood chips were disturbed, and they suddenly became a little unstable, staggering and almost falling.
Fortunately, the white ape quickly retracted his hand, his eyes lit up brightly, and he looked like "it turned out to be true."
"As long as there is enough lift, even hundreds of kilograms of iron can be levitated!" Looking at everyone's eagerness to try it, Wang Liangyu concluded, and before everyone could show their horrified expressions, he continued, "Of course
"Levitation is only the first step, and then thrust is needed. Only with thrust can we truly fly."
"Let's take the example of a bird again. The thrust of a bird is obtained by flapping its wings."
"Although we humans don't have wings, we use many practices to cast the wind spell backwards in the opposite direction, which can generate thrust and propel us forward!"
After listening to Wang Liangyu's words, everyone fell into deep thought.
Only Yuan He said subconsciously: "Isn't this a little too complicated? Two wind spells up and down, plus the backward wind spell, and casting three wind spells at the same time, ordinary people can't do it!"
After a pause, he pointed to the wood piece again and asked in surprise, "How can we create such a curvature if we subtract a wind spell?"
Wang Liangyu stretched out his index finger, shook it slowly, and said with a smile: "Do you remember what I said? Walk with the wind!" Before Yuan He could react, Wang Liangyu continued with an excited look, "Between heaven and earth, the wind
, everywhere, as long as we can accurately grasp and control their wind direction and speed, we don't need three wind spells, nor two wind spells, we only need a reverse wind spell that provides thrust, and we can ride the wind and rise.
Ninety thousand miles away, you can roam freely between heaven and earth!"
"What a saying, 'Riding the wind for ninety thousand miles, traveling freely between heaven and earth', it's so refreshing!" Fan Li couldn't help shouting, with a look of yearning on his face.
Everyone else had similar expressions when they heard this.
At this time, Xu Yuan could not help but cough lightly. When everyone came back to look at him, he said slowly: "What Wu Zu said is indeed very desirable, but the wind is an invisible thing, how can it be easily
Are you sure of it?" After saying that, he shook his head with a wry smile and said helplessly, "If this were not the case, why would farmers like us work so hard to create spells like Wind Curse?"
One of the purposes of farmers' wind spells is to deal with wind disasters.
Wind disaster is one of the five pestilences of farmers and has great harm to agricultural farming.
If the wind could be controlled, would farmers still have to worry about wind disaster?
Everyone was startled when they heard Xu Yuan's words.
Seeing this, Wang Liangyu smiled faintly and asked, "Are you giving up because of difficulties?"
As soon as these words came out, everyone woke up.
Everyone present is the head of the same family, so how can anyone be frightened by this difficulty if they are not arrogant.
Thinking of this, Sun Wu laughed loudly and shouted: "It's just a breeze, why worry, we will definitely win it in the future!"
As Sun Wu's shout rang out, everyone echoed his voice, which was very enjoyable.
Such movement quickly alerted others, and even the two people who were fighting fiercely on the platform had to stop and turn around to look over.
"Keep playing music, keep playing!" Wang Liangyu stood up and shouted toward the stage with a loud smile.
When Sun Wu and others heard this, they all laughed loudly.
The two people on the stage were stunned and subconsciously moved their hands, but they couldn't help but mutter in their hearts: "Playing music? You're not listening?"
While watching the fierce battle on the stage, other audience members glanced at Wang Liangyu, curious about what they were talking about.
"Liangyu, I feel that the explanations and arguments in the past few days have not been as rewarding as today!" Sun Wu ignored the gazes of other viewers, stared at Wang Liangyu, and exclaimed with emotion.
Kong Fuzi and others nodded in agreement after hearing this, and looked at Wang Liangyu with approval in their eyes.
Wang Liangyu shook his head humbly and said casually: "Seniors, you are so ridiculous. I just stand on the shoulders of your seniors, so I can see a little farther!" After saying that, he bowed to everyone again and bowed sincerely.
Said, "If it weren't for the seniors to open the way, the juniors would be just stupid people!"
After listening to Wang Liangyu's words, the big bosses became even more fond of Wang Liangyu and praised him repeatedly.
There is a lot of excitement here, and the battle on the Taoist stage is coming to an end. The loser gets down, and the winner continues to stand on the Taoist stage to meet his next opponent.
The next few days.
On the forum, practitioners from various schools of thought were fighting endlessly.
Beside the Taoist forum, the bigwigs of various schools of thought were having heated discussions, studying techniques and the Tao.
