I have a magical world.

In fact, Chen Xuan understands.

The passive power armor he requested did have considerable design difficulties.

This is especially true if you want to ensure the flexibility of the structure.

The flexibility here does not only refer to normal up and down movements, but also activities that can approximate human joints and postures.

At present, it is a problem for the mechanical mechanism to fully flexibly simulate human postures across the entire Blue Star.

Previously, Boston Dynamics of Bald Eagle had done a better job in this area. Their robot was the first to achieve single-legged and standing jumping, running, obstacle avoidance and climbing, and self-balancing.

Although the video released has a certain editing effect.

But the flexibility of movement is already quite smooth.

This is the knowledge of mechanical design.

Of course, it is also related to the fact that Boston Dynamics uses a hydraulic assist system, which is more explosive than traditional motor assist.

But no matter what, if you want to keep the mechanical structure as smooth as possible, there are design problems in itself.

Fortunately, Chen Xuan said that power was not needed, which reduced the difficulty a lot. Otherwise, while designing, the power system would have to be preset.

But even so, it is indeed not easy to achieve what Chen Xuan requires.

As for the individual soldier exoskeleton that had been researched and distributed more than ten years ago, it was completely unrelated to the passive power armor he requested.

Mechanical exoskeletons originated from early attempts by people to invent mechanical devices made of steel frames that could be worn by humans, inspired by beetles.

It is also commonly called "Powered exoskeleton".

It is essentially a wearable robot.

It generally includes three parts: complete machine design, driver (mechanism) design, and control strategy; the "control strategy" is the real-time human-computer interaction and control, which is the core difficulty.

But it is not armor, but a human body assist system.

It is designed to enhance the functionality of the human body, including strength, terrain crossing ability, etc.

Today, Blue Star's research and application of mechanical exoskeletons mainly focuses on two types, namely the augmented type and the auxiliary type.

At present, both Xia Guo and Bald Eagle have been issued practical models.

Xia Guo's mechanical exoskeleton started earlier, almost at the same time as the large drones, so the technology is relatively advanced.

But this does not meet Chen Xuan's requirements.

In the final analysis, it is because the mechanical exoskeleton is not flexible enough.

Most of the current mechanical exoskeletons are used on the logistics side.

Secondly, the exoskeleton is just a framework. Expanding its main body is far more technically difficult than Chen Xuan directly asking people to design a set of wearable and flexible armor.

Therefore, he can understand why Hongyu Heavy Industry failed.

Because his requirements do present considerable design difficulties.

Although it can be done with the current technical reserves of Xia Guo Machinery Design.

But it takes more effort.

Design fees of one million are also normal.

But what made him angry was the attitude of Zhang Youpan and Li Jianping who fooled him.

It can be said that it is difficult, and it is no problem to add money.

The price was set by the other party, and the promise was made by the other party, but in the end they chose to mess it up.

This is what Chen Xuan is dissatisfied with.

"Do you really think of me as a piglet?"

He suddenly sneered.

He immediately calmed down his emotions, took out his cell phone again, and dialed the other party's number again.

After half a minute, Zhang Youpan answered the phone slightly impatiently.

"Didn't I say that?"

"Go to legal channels. Once the contract is signed, this matter will no longer be under the control of the sales department."

Zhang Youpan's voice came from the other end of the phone.

Chen Xuan raised the corners of his mouth and said in an unhurried tone.

"Sorry, Commissioner Zhang."

"I admit I spoke a little too loudly just now."

"Well, I'm willing to pay a seven-figure design fee."

"Why don't we come out now and talk about the details."

"Call Mr. Li over here, and the three of us will find a place to have a drink. For tens of thousands of dollars, there's no point in talking about a lawsuit."

Chen Xuan's attitude changed suddenly.

However, Zhang Youpan was a little unexpected.

"this…"

"OK then."

"It seems you are indeed sincere."

Don’t reach out to hit the smiling person.

After Zhang Youpan thought for a while, he agreed.

As for the possibility of fraud, he never thought about it.

What era is it now?

This is Tianhai City, and the other party is not going to do anything to them for tens of thousands of dollars.

Year-round urban life and a relatively stable environment have long diluted people's sense of crisis.

Consider possible future cooperation.

And Chen Xuan's sincere attitude.

He decided to ask Li Jianping to go to the appointment again.

If the other party is really willing to pay enough design fees, then this business is not out of the question.

Hongyu Heavy Industry still has to rely on its performance to speak for itself.

As long as the order volume is large enough, performance bonuses will be increased, multi-department cooperation or even working overtime to design for him will not be a problem.

It was precisely because of this consideration that Zhang Youpan chose to agree to meet.

The two parties agreed to meet in a tavern in Dingjia District.

After hanging up the phone, the smile on Chen Xuan's face did not diminish at all.

He admitted that he had spoken loudly just now, but later, Zhang Youpan and Li Jianping would know who was the bully.

After getting up and tidying up his clothes, Chen Xuan walked into the bathroom and simply poured a handful of warm water on his face.

Then he put the key in his pocket and looked back at Ahn'Qiraj, who was nestling on the couch like a kitten.

"I'm going out."

"Maybe I won't come back until later."

After hearing his words, Ahn'Qiraj quickly stood up.

"Master, can you take me with you?"

He is about to leave Blue Star and return to Naroa.

She still wants to see as much of the world as possible.

After hearing her words, Chen Xuan thought for a moment and finally agreed.

It doesn't hurt to bring Ahn'Qiraj with you.

As a fourth-level spellcaster of both thunder and fire elements.

The extraordinary power she possesses is terrifying enough even in Blue Star.

After getting Chen Xuan's consent.

She quickly ran into the bathroom with her clothes.

After walking out again, Ahn'Qiraj changed her pajamas into a black dress.

She wore a storage necklace and bracelets on her neck and wrists respectively, which now became the best decorations.

The Void Stone can slowly change color under the illumination of light, cycling between purple and gray.

This kind of color light and shadow does not change quickly, so it does not appear abrupt, but only looks beautiful.

After changing her clothes, Ahn'Qiraj looks like a cute mage who has just grown up.

The premise is that her real age is not taken into account.
