The Star Dragon Territorial Strategic Defense Bureau, referred to as the Thirteenth Bureau.

Han Xiao's mind was racing.

Old man Lu is the core character of the hidden plot and the target of Han Xiao's trip.

It was purely an accident to meet Old Man Gao, this was a big man in a high position, Han Xiao knew that his identity could hide from others, but not from Old Man Gao.

The original plan was to anonymously deliver budding information, show goodwill first, and then reappear when the time is right, but now the plan can't keep up with the changes and has to be adjusted.

Rashly contacting the top management of the Thirteenth Bureau made his situation a little passive, but Han Xiao was rarely frustrated, and if things changed, he would only think of new methods.

Since anonymity no longer works, then simply expose it directly, show his own value, and make the other party feel that he is worth wooing, and wait for the Thirteenth Bureau to come to the door in person. The so-called enemy of the enemy is a friend, and there is a potential basis for cooperation between Han Xiao and Xinglong.

Fortunately, he had already entered the city, and the Thirteenth Bureau would have some scruples and was worried about destroying the city, so he acted cautiously, if his identity was revealed at the outpost, he would be surrounded by the army and slaughtered by others.

Changing the plan is not necessarily a bad thing, Old Man Gao's status is respected, as long as he gets a little trust from Old Man Gao, his plan will be successful for the most part.

While thinking about how to talk, Han Xiao asked, "What test?" ”

Old man Lu looked left and right, couldn't find any problems, suddenly his eyes lit up, and he pointed to Old Man Gao's broken arm: "You give him a prosthetic, he is satisfied, and you can pass the test." ”

"What's wrong with me?" Old Man Gao was stunned for a moment, but when he saw Old Man Lu frowning at him, he understood that Old Man Lu wanted to deliberately make things difficult and drive Han Xiao away.

"Grandpa, you're too much, why are you so harsh, what if you scare others away? You drink and play chess every day, hang out and walk, how long has it been since you take care of the work in the store, and you are not allowed to find an assistant? ”

Lu Qian was not angry.

Old man Lu ignored his granddaughter and looked directly at Han Xiao, waiting for his answer.

Han Xiao looked strange and emphasized: "Are you sure you want me to create a prosthetic leg that this old man is satisfied with?" ”

"If you don't dare to accept it, then leave quickly."

"I accept."

Han Xiao smiled and agreed, the [Bionic Prosthetic] drawings he obtained before were still dusting in the panel, and the drawings were all ready-made, Old Man Lu's request was considered to have hit his own hands, and he could logically have a relationship with Old Man Gao, I don't know if it was his own illusion, I always felt that the bloodline had been a bit Europeanized recently, and these days I always feel that there seems to be some kind of existence watching him.

"You've only got three hours, and I don't have the time to wait for you to build a day or two."

Old man Lu snorted coldly.

"Grandpa!" Lu Qian was angry and wanted to create a prosthetic limb, first to measure the size of the old man's arm, then draw a structural drawing, and finally create a finished product. It may take a few hours just to draw and conceive, even if the lathe can simplify the manufacturing process, but it will not be less than two hours, which is equivalent to almost no time for Han Xiao to conceive, and the final product must be satisfied with the old man Gao, which is simply deliberately difficult, and the treatment of designers is not so miserable.

However, Old Man Lu was the head of the family, and Lu Qian's protest had no effect.

Han Xiao didn't react, took out a tape measure, and asked, "Old man, is it okay?" ”

The tall old man generously took off his coat and signaled that his severed arm could be measured casually.

When Han Xiao was measuring the size, Old Man Gao was also observing Han Xiao.

was so obviously embarrassed by Old Man Lu, there was no trace of unhappiness on his face, but he was confident, and he seemed to be really capable.

"I just don't know why he was offered a million reward by the Sprout Organization."

The first time Old Man Gao saw Han Xiao, he recognized his identity. The bounty offered by the budding organization caused an uproar in the underground world, and almost all intelligence agencies remembered the appearance of "Zero", and the position of the old man Gao was responsible for such incidents, so he naturally knew it. Seeing Han Xiao, who had been rewarded, swaggering into the city, he knew that there was another officer stationed at the outpost who was corrupt, and he really had to find an opportunity to clean up the internal team.

What is the purpose of Han Xiao's visit to the Western Capital? Is it threatening? This is all a matter of concern to Old Man Gao, and at present, it seems that the other party's performance is normal, so Old Man Gao continues to observe.

Old man Lu is different from him, old man Lu used to travel between life and death when he was young, he has rich experience, and he keenly discovered that Han Xiao was contaminated with the evil aura of human life, so he deliberately made things difficult, not wanting Han Xiao to stay in the repair shop, for fear of causing trouble. However, Old Man Lu hadn't set foot in the underground world for a long time, and he didn't know that Han Xiao was the target of the budding bounty.

"Lao Lu Tou's requirements are really harsh, and he put the choice in my hands, this is to ask me to help."

Old man Gao and Old man Lu looked at each other.

Han Xiao quickly finished measuring the size, Lu Qian was dissatisfied with her grandfather's actions, and enthusiastically came up to help, saying, "Come, tell me about your idea, and we will draw the drawings together, which will save time." ”

Unexpectedly, Han Xiao declined her help and said with a smile: "No need to draw, I already have a complete idea." ”

Lu Qian's eyes widened, and she said incredulously: "It's only been two minutes, and you have an idea?!" ”

"Altair was blown into the sky by you." Old man Lu sneered, and conceived a complete drawing in his mind in two minutes, even he, a mechanical expert, couldn't do it, just with this kid? , you'll be there!

Han Xiao didn't explain much, and quickly wrote out a list of materials and equipment to be used on a piece of paper, Lu Qian was the store manager, so it was much faster for her to come and find things than herself.

Lu Qian quickly prepared the materials, she was very dissatisfied with Old Man Lu's behavior, so she had to try her best to help Han Xiao, but she didn't have much hope, with such harsh conditions, Lu Qian really didn't believe that Han Xiao could complete it.

Han Xiao picked out the materials and started working.

The raw materials of different shapes of metal, under the workmanship of stampers, chippers and other equipment, gradually became the appearance of Han Xiao's mind.

The main material he uses is a commonly used type of aluminum alloy, which is light and strong, easy to polish and shape, and some rivets, screws, and chain cables are ready-made, which saves a lot of time.

[Primary Mechanical Affinity] endowed Han Xiao with an extraordinary perception of metal components, touching the metal, he could vaguely feel the impatience of the material that was about to be polished, this feeling was fleeting, like an illusion. Mechanical affinity skills are the core ability of the Department of Mechanical Engineering, which affects all aspects of the use of equipment and manufacturing machinery in the Department of Mechanical Engineering, and the quality and manufacturing speed of primary mechanical affinity are increased by 1% at each level.

The top-of-the-line bionic prosthesis can collect electromyography signals, the wearer only needs to think, and the brain's neural electrical signals can command the arm, which is no different from the real arm, the Winter Soldier's metal arm is a strengthened version of this type, but it needs to establish a neural link with the body through surgery, and it is necessary to use the [basic electromagnetic principle] and [neural connection] of the mechanical control branch.

If this technology is deepened, it will be the colonization technology, and it can even replace all the limbs other than the brain with machines and turn them into mechanical soldiers. This method is equivalent to embarking on the road of mechanical life, the mechanical body cannot give birth to qi, and can only keep looking for stronger machinery to update its own modules, and strengthen itself with external forces, the only benefit is probably that the life span is extremely long, and there is no need to consider the hunger value and thirst value of the character. However, the mind that has lost its senses is easily affected by the whispers of the mind flowing in the universe, and is imperceptibly brainwashed by certain forces or powers, and loses itself. Unless you program your own thinking, set up a logical loop, and become a mental immune body, but in this way, you will lose your free thinking and become an intelligence that follows the program to think.

Slightly worse bionic prosthetics can use voice-activated mode, but there are also pre-requirements, which require the [basic acoustics] of the branch to be controlled.

Mechanical technology is linked to each other, and the same creation, with different knowledge, there are endless possibilities. Mechanical knowledge is a big tree, and the higher you go, the more branches you get.

Han Xiao retreated to the next best thing, moved the principle of the light power arm to the bionic prosthesis, took the mechanical power as the core, weakened the power, and used the battery as the energy source to prevent the environment from polluting the environment by spraying black smoke everywhere like the light power arm.

Old man Lu didn't know where to find a bottle of beer in a green glass bottle, and watched while drinking, wanting to see what Han Xiao could make, if the cowhide was blown out, Old Man Lu would not be stingy with his ridicule.
