When Chen Xin, Qin LAN and Mo Qingyan woke up the next morning, packed up their personal hygiene and prepared to leave, Qin Lan's prosthetic limb had been replaced with a brand-new prosthetic limb.

From the appearance, the new prosthetic limb is no different from the real arm. Even Qin LAN feels that this is the hand she lost.

But this is still a mechanical prosthesis, but the surface has been camouflaged enough, so it looks like a real arm.

For this prosthetic limb, out of the idea of making up for Qin Lan's debt, Chen Xin spent a lot of effort. He not only made the prosthetic limb the same as the real arm, but also installed sensors all over the whole arm on its surface, so that the prosthetic limb can have the same touch as the normal arm.

Moreover, the flexibility of the whole hand has been greatly improved, which Mo Qingyan and Chen Xin both experienced last night.

"Ah Xin, is this......" looking at his new prosthesis, Qin Lan was very happy, but still a little embarrassed: "I don't mean I don't like it. I just think you don't need to spend so much time on such a small thing. Your energy and time should be spent on work..."

"Why do you say this? Do we need to say this before?" Chen Xin stroked Qin Lan's hair and smiled at her: "it's just a little spare time. It's nothing, and I think I should spend more time with you, isn't it?

And you don't need to be so tangled. It's just a small thing. If you always care about these small things, you won't be like you! I still prefer the tigress who threw me in bed before, not the little cat now! "

The last sentence, Chen Xin whispered close to Qin Lan's ear, but it still made Qin LAN blush.

But this also made her worry less. When she hammered Chen Xin directly, her face became relaxed, and there seemed to be a feeling of letting go of something.

Chen Xin noticed Qin Lan's emotional change. He smiled to himself and laughed at himself. He had never found Qin Lan's personality change in recent years, which had to be said to be a great negligence.

Although busy work is an excuse. After all, he spent a year in Lucia and Europe respectively and didn't spend a lot of time with Qin LAN, but Qin Lan was the person next to him in the final analysis. He didn't even notice this change. In some aspects, Chen Xin really didn't care enough.

Mo Qingyan on one side is also happy when she looks at Qin Lan's emotional changes. Although she says that Qin Lan's personality changes have no problem in her opinion, she doesn't want her good friends and sisters to embarrass herself and suppress her true feelings all the time.

Now Qin LAN can put down some burdens, which is undoubtedly a good thing for her.

This also makes Mo Qingyan feel good. After holding Chen Xin's hand, she always wears a smile on her face.

Even the leaders who came to see Chen Xin off noticed the full smile on Mo Qingyan's face.

However, this is not the focus of their attention. Compared with the people around Chen Xin, they pay more attention to Chen Xin himself.

Of course, out of the traditional human and worldly sophistication, people around Chen Xin such as Mo Qingyan will not be ignored, and even in some ways, they are more flattering than Chen Xin himself.

Of course, these are not things that can be put on the table, so several leaders remained polite, courteous with Chen Xin and seeing Chen Xin off.

On the way to be polite to these leaders, Chen Xin asked the question that made him care: "what idea did you design and manufacture the luxury carriage? From a practical point of view, shouldn't it appear?"

Hearing Chen Xin's question, several leaders were stunned. One of them hurriedly explained with a smile: "Academician Chen, you misunderstood. In fact, the luxury carriage is actually a kind of goods. It's not so much a carriage as a built luxury suite. It's just made into a carriage, or we made it to entertain important guests like academician Chen."

"For entertaining guests? Oh, I see." hearing the leader's explanation, Chen Xin suddenly realized that it makes sense.

For train manufacturers, there is no doubt about their importance as one of the few remaining train manufacturers in China, which makes them have an important position in the national production plan. At the same time, important senior leaders and other figures often come to inspect them.

Now, no more than before, there are no hotels in the city, but the leaders can't help receiving them. The best way is to build a reception place by themselves.

For example, the carriage where Chen Xin ate yesterday and the place where he lived last night were obviously built for this purpose.

This kind of carriage that is clearly placed there and will not move is easy to manufacture. It is much easier than building a carriage. At the same time, it is much cheaper than building a reception place. Therefore, it is not surprising that the train manufacturer chooses this way.

Having figured this out, Chen Xin didn't say anything more, just joked: "can you make these carriages? What if there is really a need in this regard? For example, I want the luxury carriage to be my special train carriage now."

"What is placed there can't be moved, but we have made the relevant design drawings. If there is a real need, it can still be produced." the leader with glasses answered Chen Xin's question, but the answer was very clever.

Hearing this answer, Chen Xin nodded clearly. He knew that even if he really wanted such a luxury carriage to be his own special train, he could definitely make it with the technology of the train manufacturer.

As for whether there are drawings as early as he said, it is a matter of different opinions.

He was sent out of the train factory by several leaders and took the plane back to dome new town. Chen Xin couldn't help thinking whether he could get a special train. After all, the special train is more comfortable than a helicopter in terms of comfort.

However, this is just a thought. After all, the resources consumed by a special train are much higher than that of a helicopter.

It is also more luxurious. After all, taking the special train not only needs to consume all kinds of supply resources to maintain, but also needs Chen Xinzhen to have that time to take the train.

If there is really something urgent for Chen Xin to deal with, he will probably choose to fly.

Maybe you can build yourself a land ship? This idea came out of Chen Xin's mind
