Lu Zhong shook his head, a look of discouragement flashed in his eyes, and he endured it before he said, "Xiao Nie, I have seen this second secret key."

In general, when my great-grandfather forged a new machine, he would leave behind the design concept of the forged object. Of course, some top-secret things, he will destroy the forging method and the structure wire.

But this snail wheel lock, my great-grandfather left behind its design sketches and energy wires. Because, it is not reproducible. So this rescue operation is over.

This thing, with our current capabilities, simply can't be cracked. Even if a grandmaster comes in person, or if my great-ancestor is resurrected, it may not be able to repeat it again. Xiao Nie, I'm sorry......"

Lu Zhong didn't know how to explain it.

This was his great ancestor's proud design, but now he couldn't do anything except watch everything within ten miles of the northwest city be destroyed by the self-explosion of this top-level machine, and as the inheritance master of the Lu family. That kind of feeling is incomprehensible to others.

"Master Lu Zhong, could you please explain it clearly? I didn't say I wanted to give up! ”

Suddenly, Nie Bing broke off his drink, shocking Lu Zhong.

"Xiao Nie!"

Looking at Nie Bing's suddenly fierce eyes, Lu Zhong's heart jumped, he blinked, seemed to be able to understand Nie Bing's mood, and sighed: "Okay." The design of this snail rotor lock was inspired by my great-grandfather's biomimetic perspective. Its uniqueness is that the three locks are three in one and one cycle.

Each lock is an independent magnetic code, and each lock is interrelated and becomes a whole. But most importantly, the key and the cylinder also form a perfect complementary cycle.

The first lock is the module runner lock on the snail shell, which requires 360 modules to match. Each piece has a different shape and structure, and each piece is equipped with a pneumatic propulsion device, and the position is positioned.

The second lock is the sliding device lock of the snail's foot, and the hydraulic sliding lock module used is created with the muscle drawing simulation process, and the corresponding slide must be extremely subtle when used to slide into the lock cylinder and fit into one, which can activate the third lock, and the most critical one, the magnetic tentacles of the snail's head.

This last step will trigger the overall cycle of the entire lock cylinder and the key, the snail's head sticks out, and when it slides into the lock cylinder, if the two compartments cannot match, then its two antennae will not be attracted by the magnetic device in the lock cylinder, so that the overall cycle will not be triggered, and the lock will still not be opened. Can you understand? ”

Lu Zhong looked at Nie Bing bitterly.

At this time, Nie Bing's two brain domains had already flown around.

He knew that although Lu Zhong didn't say anything about the details such as the grade of the machinery and the accuracy of the forging, the most basic structural concept of three locks and three links in one cycle was already extremely complicated.

It was the most difficult mechanical lock he'd ever heard of.

After all, on such a key that is no more than half a palm, it is a headache to think about forging these conditions perfectly. What's more, their time is extremely limited. It's a real problem.

"Xiao Nie, it seems that you should understand what I mean. In fact, there is another key problem, that is, the level of this machine must reach the C-level four-and-a-half stars. ”

Lu Zhong squeezed out these words from between his teeth.

"C-grade, four-and-a-half-star?"

Nie Bing's pupils shrank, and if he hadn't been watching the meditation in his heart, he was afraid that it would be chaotic all of a sudden.

"Xiao Nie, I know you can forge D-rank five-star equipment. But I also speculate that you can reach three stars at most on C-class machinery, and maybe four stars beyond the limit. But four and a half stars, can you reach it? ”

Lu Zhong looked at Nie Bing and shook his head, smiled bitterly, and said, "So, this task can't be completed." Give it up. ”

"Master Lu, can you show me the drawings."

Nie Bing was still unwilling.

"You, still not dead?"

Lu Zhong looked at Nie Bing in a daze, "Forget it, let it be." ”

As he spoke, he handed a chip to Nie Bing.

Nie Bing directly inserted it into the magnetometer, and a set of data and hand-drawn sketches appeared in front of him.

The decomposed parts in the picture, according to the proportion of the actual size, the largest is the size of a grain of rice, and the small one is like a needle tip, of which the special-shaped parts account for two-thirds, as many as more than 500. It's like a bunch of dense little ants, and the difficulty of building it is unimaginable.

There are special requirements for accuracy, the positive and negative errors cannot exceed one micron, the forging environment needs to be dust-free, and the temperature must be constant.

Later, the secret bone pattern will be broken down and depicted onto these parts, and when combined, they become one. Even if one of these small links goes wrong, it is a failure. This is definitely a technique that is difficult for the Grandmaster level to do.

Nie Bing's face suddenly became solemn.

He thought he had the perfect optimization system for cosmic gears, and he could not be afraid of the other party's manuscript sketches.

But now he feels very tricky when he sees the complexity of this drawing, and the accuracy requirements of the metamorphosis, whether it is the number of parts or the requirements of forging skills.

Still, he wanted to try.

"Master Lu, if, I mean, if I can forge a qualified C-class mechanical blank, can you be sure that you can carve the perfect wire?"

Nie Bing looked up suddenly.

"Qualified mechanical blanks? Impossible Xiao Nie, I'm just a sketch. To tell you the truth, I don't know how many times I've tried it over the years, and I've tried it since I became a master, but ......"

Lu Zhong seemed to be afraid of hurting Nie Bing's self-esteem, and paused: "Give up, we still have six and a half minutes, if we move fast enough, we can save some more people." ”

"Master Lu, I think I can do it."

Nie Bing's momentum suddenly condensed, and his voice was loud.

"Xiao Nie!"

Lu Zhong's voice sank, and his face changed slightly. was already in a bad mood, but he didn't expect Nie Bing to be entangled, which made him can't help but have a seizure.

But at this time.

Nie Bing directly took a piece of carat steel, opened the gravity ring, and grabbed and locked the surrounding air force field. All the fine dust is solidified outside, and with the help of the constant temperature in the password cabin, the Void Hammer is unfolded to carry out intensive fine forging.

In fact, Nie Bing knew in his heart that this snail magnetic runner combination lock was the first time he had come into contact with it in his life, and the success rate of forging was not at all. However, he has another advantage.

It wasn't the first time he had forged this style of machinery.

Just when he was perfecting the sketch, his mind suddenly flashed to the scene when he was in the mechanical waterway, helping Uncle Tianluo repair his body.

He may not be familiar with other bionic machinery, but he has two maintenance experiences for bionic machines such as snails and snails.

As the saying goes, one drink and one peck, machinery is for the benefit of mankind, and he did not expect that one day he would use this experience.

Snort! Bang bang bang!

The light and shadow were chaotic, and a piece of carat steel with a large fingernail cover shrank rapidly under the heavy hammer, and layers of gray impurities peeled off like snowflakes, and soon a mechanical shell the size of a grain of rice was held in front of Lu Zhong by Nie Bing.

"This, this ......"

Looking at the brilliant micro-mechanical shell, Lu Zhong picked it up gently. As soon as he touched his hand, his body trembled.

Suddenly, his pupils burst out, and he raised his head and stared at Nie Bing.

After a while, he finally gritted his teeth and said, "Xiao Nie, do you really want to make the last fight?" Not afraid of death? Not holding back? ”
