The corners of Yun Xiyao's mouth hooked a smile, smiling smartly, Zhang Aoqian looked more and more pleasing to the eye, this girl is still amazing!

"It's still a girl, you know me best! Isn't that? The old man can't eat these days, and he can't sleep! Zhang Aoqian snorted coldly, "Don't mention it, the waste scum on the mountain, all of them are beautiful, self-proclaimed caster masters, bullshit, can't even talk about electronics, or you know me best, the old man's girlish heart, 10,000 critical hits." ”

It's easy to get money, but it's hard to find a confidant!

Yun Xiyao pursed her lips and smiled, and said euphemistically, "Elder is really a god!" But...... Would you like to see if it would be better to improve it? ”

"Huh? Where? Girl, where? Zhang Aoqian was worried that he couldn't find a soulmate, and when he heard that Yun Xiyao wanted to help him, he almost slapped the table with excitement.

Yun Xiyao coughed lightly and blinked. Glancing at the drawings, he pointed to one of them, which resembled a strange thing like a trebuchet, and said with a smile, "Elder, if the arm is too long here, the axis will be easy to be unstable, and the center of gravity will move back." And here......"

"Oh, look at my pig brain, yes, yes, yes, that's right." Zhang Aoqian listened while sketching on the drawings, and his mouth was babbling, "I'll just say what's wrong...... I see! What a word to wake up a dreamer! ”

It is rumored that Zhang Aoqian has a strange and tricky personality, and even the face emperor is a few words, in fact, in front of Yunxi, he is a well-behaved elementary school student!

Chen Yixing couldn't help but be horrified when he saw that every move of the two of them was in his eyes!

Does the old pavilion master still have such an approachable side? Could it be that the way you open it yourself is wrong?

"Uh...... Elder, this red cherry blossom is ......" Yun Xiyao frowned slightly, puzzled.

As a result, Zhang Aoqian came to a ridiculous deterioration, "It's good-looking!" ”

"Poof!" Yun Xiyao couldn't help laughing, laughed directly, the corners of her eyes trembled, and she said to herself, "Why do you look a little ......." ”

"What?" Zhang Aoqian's ears were not good, and he stared at the girl in front of him suspiciously.

Yun Xiyao chuckled lightly and raised her voice, "Elder, you're almost formed." ”

"Hahahaha." Zhang Aoqian laughed heartily, "That's half a year's hard work." ”

"By the way, Mr. Zhang, can I help me make something as soon as possible?" Yun Xiyao took out a drawing from her arms, "No, Zhang Lao, look." ”

"Come on, come on, old man, let's take a look." Zhang Aoqian said everything in front of Yun Xiyao.

I wondered in my heart, should I be pulled by this girl to work as a coolie again? What a good hand at seeing the stitches!

Zhang Aoqian still muttered in her heart, this girl knew how to squeeze herself, but after she saw the drawings in Yun Xiyao's hand, her old face changed.

"This, this is ...... Girl......" Zhang Aoqian snatched the drawings from Yun Xiyao's hand, completely spread them out, and his dark hands trembled, "Girl, you really got this thing!" ”

Zhang Aoqian put the drawings in the middle of the table, examined them carefully, and threw his drawings into the middle of the table, his eyes glued to the new drawings.

Yun Xiyao's face was full of black lines: Old Zhang, your hard work for half a year.

……………………

Zhang Aoqian didn't realize it at all, and all his attention was focused on the drawings in his hand.

"A simplified version, a little different from the one I said earlier." Yun Xiyao pointed to the pattern, "The power is insufficient, it is easy to carry, if you don't understand it, you can send someone to ask me." ”

The drawings in Yun Xiyao's hands are meticulously made, but they are complex and novel, and there are many mechanisms, and Zhang Aoqian may not be able to study them thoroughly for a while.

How could Zhang Aoqian wait for someone to send a message? immediately studied it, chased after Yun Xiyao and asked, "Girl, what is this for?" ”

"The safety lock is the same as the previous repeater!"

"Haha! It's wonderful! Zhang Aoqian suddenly realized.

"Where's this?"

"Leverage your strength."

Zhang Aoqian asked for an hour before he understood clearly.

"Wonderful, wonderful, really wonderful." Zhang Aoqian held the drawings, like a treasure, and was amazed, "Girl, how does it grow with your eyes in your eyes?" How could I come up with such an ingenious design. ”

The new tricks in Xi Yao's hands are endless, and they can always surprise him.

Yun Xiyao shook her head and smiled lightly, "Elder Zhang, how long." ”

"Half a month." Zhang Aoqian is full of confidence.

"Okay." Yun Xiyao was satisfied.

Zhang Aoqian suddenly asked, "Is this thing supplied to the outside world?" ”

"Not yet." Yun Xiyao thought about it for a while, and a smile hooked up at the corner of her mouth, "Let's talk about it after looking at the finished product." ”

"It's good if you're happy." Zhang Aoqian doesn't care.

This old man is completely a fan of casting, there are novelties, he forgets to sleep and eat, he does not hesitate to do anything, money is a number, there are no hard requirements. Zhang Aoqian in the Flying Dragon Hall is the finale of the battle.

Occasionally, I helped Yun Xiyao cast some gadgets, all of which were designed by Yun Xiyao herself, and sometimes she was too busy and threw half of them to him. I've been busy like a spinning top lately, and I really don't have that idle time. Others dare not guarantee that Zhang Aoqian is still more assured.

"By the way, Elder Zhang, do we still have a black fire?" Yun Xiyao patted her head and asked suddenly.

Zhang Aoqian nodded, rubbing the drawings in his hand, "There are some, enough." But there's not much stock on the mountain, so you'll have to find a way to get some more. ”

Yun Xiyao nodded, "Got it, I'm thinking of a way." ”

The black fire in Zhang Aoqian's mouth is actually explosives, and it is also one of the cores of this divine weapon!

Yun Xiyao's design, coupled with Zhang Aoqian's craftsmanship, is infinitely powerful.

Sulfur, charcoal is easy to find, saltpeter is difficult to do, I found a little by chance before, there is not much left, it is really not possible to go out in person.

"Girl, that's right." Zhang Aoqian flicked his sleeves and pointed behind him, "This is Chen Yixing, the owner of the branch building of the Cloud City Flying Dragon Hall, who is barely half a disciple of the old man, and he is a good manager in management." ”

Zhang Aoqian's eyes were still glued to the drawings when he spoke...... Chen Yixing stepped forward and finished for a while.

Yun Xiyao nodded and looked at Chen Yixing.

"Look at your useless look." Zhang Aoqian didn't raise his head and teased with a smile, "What are you still pestleing for?" You really want to see her? ”

Chen Yixing's eyes widened, he could almost confirm the identity of the person in front of him just now, but he didn't get an answer, so he didn't dare to speak rashly. Hearing Zhang Aoqian's words, all kinds of emotions gushed out.

"Subordinate Chen Yixing, meet the lord!" Chen Yixing stepped forward and knelt down on one knee respectfully.

Yun Xiyao glanced at Chen Yixing lightly and was silent...... Chen Yixing sang a cool song to himself, it's over, just now the guard lord was offended, and he followed him to eat and work, how is this good?
