Wu De Xingjun was a little dazed, and after a long time, he woke up from a dream and asked, "Why?"

"Because according to the laws of mechanics, the action of force is mutual, you know!"

Xing Wenshi really wanted to learn from scholars and professors to push the bridge of his glasses, but he found that he was not short-sighted, so he gave up, but his fingers still wiped his nose and said: "To put it simply, it is how much power you exert on the Djinn God, then you will be exerted by the same power." ”

"Red scarf, I can't understand, Wude Xingjun pushed me, but I didn't fight back, why did I exert force on him as well?"

Xing Wenshi: "...... You can understand it this way, but in fact, if you are replaced by a wall, the same principle applies. ”

Although I couldn't understand what Xing Wenshi was saying, judging from the current situation, whether it was Martial De Xingjun, the Roaring Sky Dog and the Giant Spirit God, they all felt that the master in front of him was very awesome.

Otherwise, how could such an unfathomable language be spoken!

"Teacher, as you said, does this have anything to do with the fact that I can't use my weapons in full sync?"

"Yes, of course!"

Xing Wenshi actually wanted to say to him, you have so many special ways, can you play things that are beyond your ability smoothly? But thinking about it like this, I am afraid that it will hit his self-confidence. Besides, I care about these immortals humanely, if I say some blows, wouldn't it be contrary to my mission?

Be more rigorous and convince them so that everyone can be happy.

"Actually, it's simple!"

Xing Wenshi looked at Wu De Xingjun with embarrassed eyes and said, "If you use your weapon, you will be blocked by the air, do you know?"

As soon as these words came out, the other three were shocked.

"Red Scarf, you're not kidding, the air can still stop the divine soldiers?"

The Howling Dog scratched at the air with his hand and said, "Isn't there nothing in the air?!"

"Don't underestimate the air!" Xing Wenshi felt that his limited knowledge of physics began to burn in his abdomen, if one day his physics teacher knew that he had studied physics in the first year of junior high school and could preach to several immortals so awesomely, then his physics teacher would definitely be happy and glorious for teaching such an awesome student of his own.

Feeling the momentum around Xing Wenshi, the other three hurriedly sat down, they wanted to listen to the master's teachings.

"Ahem!" Xing Wenshi began to speak, "You're right, the air looks like nothing to the naked eye, and as for me to explain to you ionic molecules and the like, you definitely don't understand, but it's okay, let's talk about something simple." ”

"Then please ask the teacher to quickly solve our doubts!"

"Well, let's just talk about the air," Xing Wenshi said, pointing to the front of him, "Actually, we are all the same, we can't see the air, but we can feel its flow through other mediums. ”

"What medium, air can be felt?"

"Nonsense, whenever the wind blows, what is blowing in the face, is the air, it is precisely because of the force that the air flows, we can feel the wind, to be exact, feel the air!"

"I see!"

The three of you, you look at me, I look at you, and suddenly I realize.

"For example, if you throw a stone into the air, if there is no resistance in the air, it stands to reason that you can throw a stone into the sky!"

"Oh, I see, it's because the air has resistance, so it's consuming the power you threw and that's why it's falling, right?"

Wu Dexingjun's eyes lit up, he felt that now was the time for him to fully understand, and the whole person couldn't help but feel complacent at the moment.

"This ...... Broadly speaking, that's right," Xing Wenshi pondered for a moment, "Specifically, it also involves the gravitational pull of our water polo and the like!"

Originally, I thought that I seemed to understand it, but when I heard any gravity, let alone Wude Xingjun, even the Howling Sky Dog and the Giant Spirit God were confused again.

Sure enough, the man in front of him is a master, he is so unfathomable, too powerful!

"Wude Xingjun, now let's talk about why you have the problem of forward swing when you use weapons. ”

"Please ask the teacher to teach me and solve my doubts!"

"I have to say, your Taoism is very high, and your own strength is very strong, in this way, you first take a sharp sword and try it, and then feel the friction and resistance of the air with your heart!"

When Wu De Xingjun heard this, he immediately summoned a sharp sword, and then swished twice.

"How's it going, do you feel like there's no resistance at all?"

"Teacher, it's true!"

"Okay, you take out all your ninety-nine-nine and what Bihai Chaosheng swords are, and play twice. ”

Wu De Xingjun did so, and the entire room was shining under the flying of swords.

"How's it going, do you feel it?"

"Well, I feel something, there's a little bit of condensation, could it be that this is the friction of the air at work?"

"That's right, you're so right, you use a sword to burst your own strength, so you can ignore the reaction friction of the air, but ninety-nine-nine is different, the air exerts friction on the ninety-nine-nine sword, which is equivalent to you bearing ninety-nine-nine friction force, the so-called accumulation of small amounts adds up, not to mention what kind of terrifying concept your five-nine-nine-nine friction force adds!"

"I see, I see!"

Wu De Xingjun shed tears of emotion, "Teacher, I finally understand, it turns out that it is not that I can't walk at home by myself, but because the resistance of the air is too great, no wonder I have a momentary forward swing, and now I finally understand!"

Xing Wenshi only felt that the egg hurt very much, okay, he changed his method to comfort him, this is good, he dared to think that his Taoism was a little bit worse before, and he knew why he bent so much!

But seeing that he was so excited, Xing Wenshi couldn't hit him, nodded and said: "So, it's not entirely a good thing that there are more weapons clones, although it's a little cooler and a little more eye-catching, but you also have to be relatively mature and have more friction, so I advise you, if it's not necessary in the future, put aside those fancy and impractical ones, let's have something capable!"

"Yes, yes, yes, listening to the teacher's words is better than reading for ten years, thank you, teacher!"

"Okay, as a messenger to communicate with the heavenly realm, I will tell you that these things are necessary and should be done, and you don't have to be too polite. ”

Xing Wenshi wiped his cold sweat, okay, he finally flickered one, and saw that Wu De Xingjun in the system had recovered 10% of his divine power because of the humanistic care, which made Xing Wenshi feel that he was still very effective in this blind break!
