The engineer finally agreed to make these two things for them, which was not an immediate pleasure, but he said that he had to make the sketch first, and let them wait.

The horrible old man sat there writing and drawing, his face more serious when he became serious, while Worm Ting played with his wheelchair and sat on it with a wind brake. Lu Su also wanted to try this magical wheelchair controlled by the center of gravity, but if he was embarrassed to speak, he would definitely be scolded.

"Master Tie, can I ask something?" Lu Su asked.

"Can't!" He focused on sketches on paper.

"How was Worm Ting adopted back then?"

He turned his face to glare at Lu Su: "What the hell are you here for?" ”

I had to keep my mouth shut.

After five minutes, he had sketched out the sketch of the gliding backpack for the two of them to see, and Nishiki was pleased with the appearance, saying, "It would be cooler if it was black." ”

"I buy my own spray paint, I don't care about the color! In addition, I added an upside down siren to you, this thing will break if it flies upside down, which is very dangerous...... Although I wish you fell to your death. ”

"Thank you so much, old cripple!" Jin Duan said gratefully.

He turned to Lu Su: "The drawings of the other missile dart are already very complete, there is nothing to add, what requirements do you have for the appearance." ”

"Please borrow a pen and paper." Lu Su took the paper and drew it, "Let's make it look like the sword in your hand, it's so cool!" ”

The engineer took it in his hand and looked at it, and "bang" tore it in half from the middle: "It's ugly, it's still the appearance of a ten-square knife." (Five ten-square knives, Chinese-style darts, you can take a look)

"Then why are you still asking my opinion?"

"What if we see the same thing? Tingting, take out your ten-square knife and show it to him. ”

"Oh!"

Worm Ting took out a dart from her bosom, shook her hand, and felt a sharp wind pass by, and a five-petaled flying knife trembled slightly and nailed to the armrest of the engineer's chair.

He pulled out the ten-square knife and held it in front of his eyes: "I use it as a template to build your missile dart, because the size is too small, the power system is limited, so if it wants to fly, it must rely on your throwing." ”

"Throwing? Isn't that just like a normal dart? The problem is that I don't. ”

"You don't understand the drawings, the designer also means this, throwing is power, and the built-in thruster is used for fine-tuning...... In other words, you just throw it and it will automatically hit the target! ”

"I see!"

"This kind of thinking is really a cross-era in the history of weapons, but fortunately this person is not a peer."

"Is there a lot of competition in this industry?" Lu Su asked with a smile.

The engineer patted his broken leg: "Of course! "This disabled leg was broken by a jealous peer? It's unimaginable!

He scratched his chin: "By the way, are you rich?" ”

"Why do you ask this, I don't have much money."

"Missile darts are expensive to build, and they are one-time consumable weapons, and this kind of thing is used in large quantities, and it costs a lot of money." He glanced at Lu Su and joked coldly, "The modern version of Huang Tianba? ”

Huang Tianba's dart is said to be made of gold, and I don't know if I have to go to the scene to recycle it after every fight. Lu Su heard that there was a money dart in the past, which was used to thin the edges of the real silver ocean as a dart, which could be carried in the purse to hide the killing machine, of course, it was also a very expensive weapon...... But he didn't have to think about this kind of thing.

"Just build one."

"One? All right! ”

"Hey, don't you ask why?"

"Don't bother to ask, it's not for me anyway."

"There's another problem...... Lu Su looked at the sharp dart in his hand, "This shape is not easy to carry." ”

"Humph!" As soon as he pressed the middle of the ten-square knife, the five points immediately retracted and turned into a large button, "It's easy to carry." ”…,

"I see!"

"This was designed by Tingting's father, he has devoted his life to improving cold weapons, but unfortunately he died so early......" After a short period of nostalgia, he raised his head, "If it's okay, you guys get out, come and pick up the goods in a week." ”

"Then we're leaving." Lu Su added a sentence in his heart: "Old cripple!" ”

"Wait."

"What's the matter, old and crippled?" Lu Su said in his heart, but he was very polite: "What else is going on?" ”

"What is the relationship between Tingting and you?"

"Good friends."

"You live together?" His eyes were as stern as those of a father examining his future son-in-law, obviously misunderstood.

"Although they live together, they are actually in the same room."

"Oh, let's go."

When he left this private factory, Lu Su felt greatly relieved, and Jin Xuan said, "This old thing has a really bad temper. ”

"Uncle Iron is good."

"Where is it, always put on that stinky face, who to see."

"Talented people have quirky personalities." Lu Su said.

After a day of wandering around H City, the three of them went back that night, and after waiting for a week, the three came to pick up the goods, and as soon as they entered the door, they saw the engineer wearing a protective mask grinding a part on the depot, making sparks fly, and the three had to wait quietly.

He finally finished his work and took off his mask: "You guys are here." ”

"Let's pick something up."

"It was done two days ago, on the table over there, go get it yourself."

There were drawings on the table in a mess, and a bunch of snacks were placed in a conspicuous position, with a small note "for Tingting" pasted on it, and the two searched for it, and finally found the gliding backpack in an inconspicuous corner under the table, and Lu Su found his missile dart in the garbage basket, not even the outer packaging, probably accidentally dropped.

Although it is not taken seriously, I am still very excited when I get the real thing, the shape is even cooler than I imagined, and when I press the button in the middle, the sharp blade pops out with a "bang".

"Play with me! Play for me! Insect Ting said excitedly.

"No, high-tech things, how can I play with you."

"It's stingy!"

The engineer came over in a wheelchair at this time: "Just play with Tingting, isn't it just hundreds of thousands, and I will compensate you two if you break it." ”

"Oh! Here, please help me break it. Lu Su stuffed it into Worm Ting's hand.

"The initializer is blank, which means it's no different from a normal dart right now." He explained while looking under a bunch of drawings, "There is a G in the memory, this is the data line, you can program it yourself, and the code is JAVA!" Will you do this? ”

"Yes...... Will be a little! "The robot sent by Professor Wei has only been playing with me for a few days, and I have only learned a little bit of programming, which is a cold sweat when I say it.

"I'm a college student anyway, I don't understand JAVA, you can die."

"Yes, yes!"

Jin Duan has already put the gliding backpack on his back, and with a bang, the pure black leather texture of the wings immediately opens, more modern than the original one, and looks more cold.

"Oh~ Bat Warrior, transform!"

"The top speed of this thing is 180 kilometers per hour, and it can fly for three hours on fuel, and it can glide and land without fuel...... In other aspects, you will understand it by flying a few more times. ”

"Thank you, I love it so much." Jin Duan said happily.

"Actually, this kind of thing has been conceived for a long time, but unfortunately, no matter how strong the skeleton is, it can't withstand high-speed flight and flashy things."

But it's a special case for Jinduan, who has an auxiliary arm.

"I'll go out and try." Jin Duan said and ran out.

Waiting for her process, the engineer was busy again, Lu Su looked around the house, the boy has been interested in machinery since he was a child, and he liked those strange mechanical parts very much, but he didn't expect to see familiar things in it...... Wang Wu mecha! A half-finished Wang Wu mecha. …,

Lu Su asked unexpectedly, "Master Tie, did you make this thing?" ”

"That's? Yes. He bowed his head and said as he worked on the parts, "That's an early work, a smaller and higher-performance battle mecha based on the Rabbit Warrior mecha, and I'm very satisfied with this work." ”

"Do you know who's using it?"

"I don't care who the user is, I'm just a blacksmith, and the blacksmith is not responsible for the swords that are sold...... Boy, I'm building the third generation right now, and you'll see that in a few years. ”

"Ah, the third generation!" Are you going to get together the zodiac, this strange set of mechas.

……

"Senior, we've been here for ten days now!"

In the cavern of the volcano, the old man and Wan Rongbing were lying on the ground like refugees in the disaster year, surrounded by bags of convenience food, and their expressions were indescribably haggard. Liu Mengyuan insisted on guarding here, and the two had no choice but to accompany them to the end, eating in the volcano is a strange thing, filling the copper kettle with water and hanging it with a rope, boiling the pot after a while, and then using boiling water to make noodles. The water is hot spring water, and the unpleasant taste of that mineral is needless to mention, and the old man who has eaten boiled eggs in the hot spring for the past two days has eaten him to the point of dying, and his whole body has red spots.

Going to the toilet is even more painful, going to the toilet in front of the crater, after the incident, little JJ and his ass are hot, and it is unspeakably uncomfortable. And the danger of falling can scare people into constipation, Wan Rongbing made a self-made pull rope to prevent falling, once the old man went to the toilet when the pull rope broke, he kept his pants on the ankle in the state of picking up Wan Rong Bing on the edge for a few hours before waking him up, will save him up, the tragic situation can be imagined.

"The heavens will descend on people, and they must first suffer their minds and muscles." Liu Mengyuan said with his back to them.

"Senior, I heard that there is a small town down the mountain, so we don't have to wait here...... Why do you have to look for guilt here? The voice of the last sentence was inaudible.

"Aren't you excited to watch my plans come day by day?"

"I want to die...... I really want to eat hot pot. Wan Rongbing pouted, fantasizing about the outside world.

"Want to eat hot pot? I will fulfill you. ”

"Wow, senior, did you agree?" Wan Rongbing jumped up.

"Drag the table over, wake up Xing Lao, let's eat hot pot." Liu Mengyuan sneered and stretched his fingers, "Do you think you can win me by eating hot pot?" Don't be naïve! ”

"Senior, you seem to have misunderstood."

(Sichuan mahjong is called eating hot pot!) It's so cold! ）
