The people in the carriage looked at Nangong Linyu at the same time.

I saw her raise her smooth chin: "Lord Chu is a wind attribute, so please add some wind to our wheels along the way......"

Add wind?

The crowd was puzzled. Nangong Linyu didn't bother to explain.

Yuan Yuan was stunned for a moment, and then laughed out loud! !

Absolutely absolutely amazing!!

It's worthy of a young lady, it's just waste utilization, waste utilization!

Her heart came into Nangong Linyu's mind, and Nangong Linyu couldn't help but open her eyes and look at her.

It's a good word, she likes it!

The rest of the people saw Yuan Yuan smiling weirdly, and Qin Su said, "Add wind, what's the use of this?"

"I don't know this......" Sitting outside the carriage, Di Wei kept his ears pricked up and eavesdropping on the conversation inside, and when he saw Qin Su asking, he said triumphantly: "When the carriage is driving normally, when the horse's hooves walk forward, there is a tendency to move backwards relative to the ground, and the ground will have a static friction force on the horse's hooves that hinders the movement trend, and the direction is forward, so the horse's hooves can move forward without slipping; Therefore, if the wind is added under the wheels, the rolling friction is reduced, and the carriage will travel faster...... which is the same reason that modern maglev trains generate maglev through electricity, so that the train is suspended on the rails and runs at high speed.

The refreshing wind blew past my ears, and the trees on both sides quickly faded backwards.

Wei narrowed his eyes, a flash of nostalgia on his face. As a demon spirit, he has gone through countless eras, and the civilization of China is the most advanced.

He had been in school for a while, and he had heard all this knowledge in school.

The nightmare was still silent in his memories, there was silence in the carriage, Qin Su, Chu Jiang, Song Qi and Murong Nuolan looked at each other.

He...... What are you talking about?

Nan Xiaoxiao shook his head, although he had been with them for a few years, they often talked well, or some actions, which made him puzzled.

Seeing that Nangong Linyu was not clear, Chu Jiang and the others glanced at Qin Su: What do you mean? Why don't you ask?

Qin Su gave them a look back: he didn't feel very good, and it seemed that he was very ignorant......

Song Qi: If you want to ask, you can ask...... What so much nonsense.

Qin Su was embarrassed, and couldn't stand the bombardment of everyone's eyes in turn, so he had to say weakly: "That...... Frictional force...... What is it?"

"Poof!!"

Nightmare one stumbled out of the carriage. The sound of falling to the ground was heard quickly.

"Eh, Wei, what's wrong with you?" Hearing the voice, Qin Su covered his heart and poked his head out of the carriage. But I saw that Wei was sitting well, but there was some dust in the corners of his clothes.

"It's okay, leave him alone, he may be a little motion sickness......" Yuan Yuan waved his hand, desperately holding back a laugh: "Leave him alone, the ...... who talks nonsense for a day" is still frictional?

Nangong Linyu pursed her lips and seemed to be laughing.

"Ahem"

Qin Su's face turned pale and he coughed with difficulty.

"Eat this...... Nangong Linyu frowned, took out a few pills from the Demon Domain, and spread them in the palm of his hand.

"Okay...... looked at the plain white palm, Qin Su picked up a pill and threw it into his mouth, chewed it, and showed a touch of joy on his face: "It tastes weird...... Well...... When I first ate it, it was bitter and a little sweet aftertaste......"

Chu Jiang looked at Qin Su still squinting his eyes and reminiscing, and his white fingertips pinched the pill. His eyes seemed to be covered with a misty fog, making it impossible to see what he was thinking.

"Eat...... Tastes good!"

Qin Su pursed his lips and urged.

"What is this?"

Chu Jiang asked very weakly, he was injured more seriously than Qin Su, and at this time, he also had more qi coming out than entering. Nangong Linyu could see that he was trying hard to make himself speak louder, but he was like that, no matter how hard he tried, he couldn't hide his weakness.

"Poison ......"

Nangong Linyu bent her eyes, revealing a smile, and her tone was a little weird.

Chu Jiang's hand trembled, glanced at her, and still took the medicine. Suddenly, a clear stream began to flow slowly down his veins, repairing his injured veins inch by inch.

I've never eaten pork, I've always seen a pig run!

Although he didn't know much about pharmacology, he could still feel the obvious changes in his body. The originally weak breathing gradually began to ease out, and the strength of the weak body was slowly recovering, if it was poison, it was estimated that he would really have to go to hell now.

Moreover, this medicine was significantly different from the pills he had taken before—it worked almost as soon as he swallowed it. He had never heard of or seen such a quick medicine, and she took out so much without blinking her eyes, and gave them all of them?

Chu Jiang's face was slightly pale, and the eyes that looked at him were even more curious.

Seeing that Qin Su and Chu Jiang were fine after eating, Song Qi slowly picked up one, but was slammed down by Murong Nuolan. "Brother Qi...... You don't want to eat .........."

"Lan'er..."

The round pill rolled down to Nangong Linyu's feet.

"Brother Qi...... I'm sorry......" Murong Nuolan wiped the corners of his eyes and glanced at Nangong Linyu cautiously, "Lan'er is just worried, just in case...... In case this medicine ......"

She didn't finish speaking, but everyone in the car understood what she meant.

Nangong Linyu's eyes darkened, and she withdrew her palm. Although she has a lot of medicine, she can't be disliked by others.

Moreover......

Nangong Linyu's eyes swept over them.

Qin Su and Chu Jiang looked in tatters, and the wounds on their bodies turned outward, revealing the flesh of Bai Sensen inside, which looked shocking. And Song Qi and Murong Nuolan, their clothes are just a little messy, at most they can be regarded as dusty and dusty.

Moreover, if her feeling was right at that time, when the last lightning bolt struck, he clearly saw Song Qi pushing Chu Jiang, which caused Chu Jiang to suffer from that lightning directly.

"Miss Murong...... Lin Yu: That's a good intention...... I've eaten it with Chu Jiang, no problem!!"

Qin Su's image of Nangong Linyu was not bad, but now she not only saved them, but also generously gave away medicine, so her favor for her skyrocketed, and her title directly changed from "Nangong girl" to Linyu.

He is such a simple and rude person, others are good to him, and he is reluctant to be wronged by others.

Nangong Linyu looked at Qin Su, and suddenly felt that he was very similar to Dongfang, and couldn't help but take a few more looks.

Noticing his eyes, Qin Su scratched his head embarrassedly.

"Who knows if there is a problem with the rest......" Murong Nuolan muttered. Even Qin Su, a guy who lacked roots, felt that something was wrong with her.

"Spend the belly of a gentleman with the heart of a villain......"

Nangong Linyu's ears were tipped, and listening to Qin Su's low muttering, she suddenly felt a little funny.

Didn't this kid protect the two of them desperately before? Why are you not happy now!

What she didn't know was that Qin Su and Chu Jiang didn't like this pretentious eldest lady very much, and now she repeatedly slandered her friends, making them even more disgusted. If it weren't for Song Qi's deep love, the ghost would be willing to care if she lived or died.

"Miss Murong...... If Lin Yu wants to harm us, there is no need to rescue us. In this way, she can not only achieve her goal, but also watch a show for free...... Not to mention messing with Huangyuan Palace!!"

After being silent for a long time, Chu Jiang spoke slowly, but his tone was not so friendly.

"That'...... That's ......" Murong Nuolan didn't know how to refute for a while.

Qin Su interrupted her with a cold snort: "Why did you get into trouble with Huangyuan Palace, and still refuse to tell the truth?"
