After thinking about it for a while, Li Dawei guessed the dirty thoughts in everyone's hearts.

Damn, this time it's even darker!

Li Dawei resisted the urge to scold his mother and said: "That's a latent killer who calls himself 'Ximen Xue'"

'Simon Snow?' Wind, flowers, snow, night's 'Simon snow. "'Don't wait', who was immersed in the hidden weapon of the mechanism, suddenly exclaimed.

Finally met someone who understood, Li Dawei's tears were about to come out, and he nodded and said, "It's him!" ”

"He... That..."Mo Wait's tongue was a little knotted, and he took a deep breath and said: "That's the master of the 'Six Grades', it is rumored that 'Sima Wudao' can become the Lord of Linfu City, and these four people have contributed a lot." ”

Li Dawei said lightly: "He said it himself, and now it's 'six grades'"

"......" Mo was speechless, and said with difficulty after a while: "Legend has it that this person likes white clothes, white horses, and is as beautiful as a woman, but he is cold-blooded and ruthless, and he never lives under the sword." ”

Everyone looked at each other again, things were not as imagined!

"What's so good about a sissy" Li Dawei was not interested in this kind of pseudo-mother, and said casually: "If you are interested, you can take a look and deal with it after reading it." ”

must be interested, especially a few female comrades, Wang Fuli is also full of curiosity, the master of 'Liupinshang', I just heard it occasionally when I was selling goods around before.

Don't wait to be left behind.

Li Dawei smiled: "Do you see anything in this pair of hidden arrows?" ”

Mo hesitated for a moment and said, "Lord Hui, the maker of this thing is a cousin of mine, named 'Mo Xiaojun'."

"Huh? How do you know?"

"The utensils made by the children of the Mo family have secret marks, and others can't understand them, but we can tell them at a glance."

Li Dawei thought for a while and said, "How much older is your cousin than you?" ”

"Half a year old!"

"Oh, that seems to be okay, the third grade is second-class, slightly stronger than you."

Mo was a little embarrassed and said, "This sleeve arrow actually belongs to the fourth grade!" ”

Li Dawei wondered: "Didn't you say that being able to fire in a row is 'three grades', and 5 arrows each time is 'second grade'?" How can I skip the 'third grade and second class' and become the 'fourth grade'?"

"Well, there are some details that I may not have made clear," Mo explained: "The number of bursts is three times, and if it exceeds three times, the difficulty of the mechanism design inside will increase exponentially."

After finishing speaking, Mo Yixian didn't know how to disassemble the sleeve arrow, pointed to the parts inside the sleeve and said: "The space for the sleeve arrow is limited, and each shot must be an independent part, so it must be designed very precisely." Burst crossbow arrows, the more difficult it will be. Therefore, this sleeve arrow can be designated as 'four grades and three grades'"

"You can't do that?"

"My craftsmanship can't be reached" Mo Yixian shook his head, and then sighed: "Mo Xiaojun has reached such a state at such an age, he is indeed a genius in this vein, and he is one of the children of the Mo family who is most likely to impact the 'Eight Grades'. ”

Li Dawei looked at the dense and criss-crossed internal structure inside, and it was indeed very fine, and nodded. Then he asked, "Are all your crossbow arrows fired through the bowstring?" ”

"Yes, lord, it's similar to a crossbow arrow!"

"Then why don't you use it any other way?"

"Huh? What else is there to do? ”

Li Dawei sighed in his heart, it seems that the thinking of the children of the Mo family is limited to this aspect, and of course it tends to be extreme in this aspect.

Take off the claw on the waist casually, twist it into a twist shape, and then let go, the claw automatically rotates, Li Dawei said: "This is the rotational force, which can produce centrifugal force."

I took a branch in my hand, held one end, bent it lightly with my hand, and then let go, and the branch bounced back, saying, "This is elasticity."

Jumping up, then falling, and saying, "Why do we jump up and end up on the ground, and everything falls down, and it doesn't fly all the way to the sky, because of gravity." ”

The first two 'don't wait' are easy to understand, but the latter one directly made him stunned, and muttered: "Yes, things are falling down, why not go up?" What is gravity? ”

Li Dawei said in his heart: It's not good, if you don't get it right, it will make people think of it, and you shouldn't put forward the 'gravity phenomenon' as a problem. "I mean that striking a crossbow arrow is the result of a 'force' action, and there are many other ways to choose from it, so it doesn't have to be so complicated!" ”

Mo Xian suddenly realized and said, "yes, why not use it any other way?!" Then he shook his head dejectedly, "Everyone has thought about other methods, and now the one used is the best one that has been proven." ”

Li Dawei said with a smile: "Creation, must not limit thinking." This time, I can give you a hint, for example, the soft sword I asked Xiong Da to study just now has a very strong elastic power, and it can be completely stronger than your current method if it is properly designed. ”

"But, I don't have such materials!"

"You melt the sword and make it into the shape you want, just use it"

“...... Lord, it's an extraterrestrial meteorite, something that can be met but not sought, how can it be so damaged. ”

"I won't use the sword, just stay there and see, you can study something, even if you can use it to the fullest."

'Don't wait' knelt on the ground with a puff and said in a choked voice: "Thank you, lord!" ”

Li Dawei stretched out his hand to help him up, and said with a smile: "What a big deal." Things are not important, talent is the most important. As long as you have a motivated heart and are willing to study, I will fully support you. ”

'Don't wait' broke free, knelt on the ground again and kowtowed respectfully three times.

Alas!
