Xiao Yuhuai walked over, picked up the dragonfly, and touched the dragonfly's body as well, and the dragonfly was able to fly.

"This is a bamboo dragonfly, and the mechanism in it is similar to the mechanism in the bouncing frog."

Seeing this, Liu Ci couldn't help but nodded, she was now a little surprised by the wisdom of the ancients, although there is no developed science and technology here, but it is indeed not inferior to others in terms of creation.

"This is also what Master Ban did?" Since it's the same thing, the person who made this thing should be the same, right?

Xiao Yuhuai nodded and said calmly: "Everything on the third floor is made by Master Ban. ”

Liu Ci began to be a little curious about this class master, the things in it look ordinary, but if you look closely at the patterns carved on it, it is not something that ordinary carpenters can make, plus the mechanism in it, this class master is afraid that he is not an ordinary person.

"What a craftsman!" Liu Ci was also a little obsessed with this thing, if this technique was used in the manufacture and development of weapons, it would definitely have a bright future.

"Hahaha, which girl is praising the old man?" Liu Ci didn't pay attention to it, and actually said what she was thinking in her heart, but a voice came out of nowhere as soon as her words fell.

Speaking the voice seems to be very close, but it is far away, saying that it seems that the voice is in the east, but it seems to be in the west, Liu Ci looked around and did not lock on to a correct target.

"Boy, it's rare to see you bring a girl to me." With the sound of the mechanism turning, a low, crutche-clad little old man walked out from behind a bookshelf south of Liu Ci.

"Master Ban, this is my fiancée, Liu Ci." Liu Ci couldn't help but be a little shocked when he saw Xiao Yuhuai's appearance, in the past, he watched Xiao Yuhuai treat everyone else with a majestic and inviolable look, but now he is respectful to this little old man who has just come out, this is Master Ban?

While Liu Ci was in a daze, Xiao Yuhuai quietly tugged on her sleeve and said in a low voice: "Ci, I've seen Master Ban soon." ”

Although Liu Ci still has a lot of questions, he still honestly salutes Master Ban.

"Okay, okay, old man, I don't like these imaginary things, female dolls, you just said that these mechanisms are used in weapons? Do you know what this is about? ”

Master Ban has been dealing with wood all his life, and the crossbow used in the army of Chu is currently researched by Master Ban, and now he is developing a new weapon, but he has not been able to get the essentials for a long time, and has not succeeded, and now when he hears Liu Ci's remarks, he can't help but also want to try his luck with the idea of being a dead horse as a live horse doctor.

Liu Ci saw the little old man's radiant appearance, but she couldn't bear to refuse him directly, she really didn't know much about this aspect, she just saw a book about this in modern times.

"This ...... Master Ban, I don't know much about these things, but I've just read a similar book. ”

Liu Ci originally thought that if he said it more tactfully, the little old man should not tell her so much, but who would have thought that after hearing this, the little old man not only did not give up half a point, but became excited.

"Books? What book? Who's the Author? What does it mean? ”

Faced with such a sudden question, Liu Ci was a little confused, and glanced at Xiao Yuhuai beside him, what is this person so excited about?

Xiao Yuhuai smiled and explained: "Resignation, as far as I know so far, Master Ban is the only and first organ master in the Chu State, so the book you are talking about is naturally extremely precious to Master Ban. ”

Hearing Xiao Yuhuai's words, Liu Ci couldn't help but be stunned, was what she just said too reckless? After all, she didn't know that this thing would be so scarce in this era, would this expose her?

When Master Ban saw Liu Ci's speechless appearance, he thought that she didn't want to say what she knew, so he said: "Female doll, if you can tell me the book you read before, you can choose these three layers of things, and I will give them all to you!" ”

Liu Ci glanced at Xiao Yuhuai again, something is not something or something, it is not that important at all, but is she really okay when she says that thing?

Xiao Yuhuai looked at Liu Ci's appearance, and nodded encouragingly, just say it bravely, it's not a big deal.

She is naturally trustworthy about Xiao Yuhuai, forget it, if they ask the question of where they saw it later, they can just make up a reason.

"Dare to ask what Master Ban is studying now? Can the little girl be allowed to take a look? Most of the things in the book she read were pictures, and there were not many textual explanations, so if she could see them, maybe she would be more helpful.

Obviously, Master Ban also had some scruples, and when he heard Liu Ci's words, he first looked at Xiao Yuhuai and hesitated.

However, Xiao Yuhuai played a very good role in regulating between the two of them, only to hear him say: "Master Ban, since Ci Ci has seen the relevant books, you might as well let her go in and take a look, if she can help you, it is naturally the best, if she can't help you, it will not have other effects, Ci Ci is my person, I can trust her!" ”

Hearing this, Master Ban agreed after some thought.

"If that's the case, let's go in together."

After Master Ban said this, he first turned around and walked towards the place where he had just come out, Liu Ci and Xiao Yuhuai glanced at each other, and the two also followed.

After arriving inside, Liu Ci found that this place was actually a cave.

"It looks like the space inside should be very small, but I didn't expect it to be so large, this mechanism is really extraordinary."

It wasn't until they reached the deepest part that Master Ban stopped with them.

"This is what I've been working on for the past two years, and I always feel like it's about to succeed, but every time it's tested, it's almost meaningless, what might the girl see?"

There was a square box on the wooden table in the middle, which looked no different from the girl's ordinary dressing box, but the faint flickering pinhole clearly told Liu Ci that this thing was not just a box on the surface.

"What is this?"

"I named him Rainstorm Pear Blossom Needle, but it's still immature...... Don't touch it! Master Ban was still talking when he saw Liu Ci step forward and pick up the box and wanted to open it, and he was so frightened that he shouted out loudly for a while.

But fortunately, it was precisely because of the incompleteness of the mechanism that the needles he arranged in the box did not shoot out.
