It seems that the people in Momen are very eager to obtain the identity of this so-called scientific researcher, and they all seem to have been beaten with chicken blood, and they blushed and shouted: "Understood." "It seems that everyone regards this official identity as their own.

Seeing Momen's morale, Mozu nodded with a smile and said: "Qingquan, the exam can begin, tell me how to test this exam, whether it depends on carpentry or iron smelting, we Momen people are all good hands." ”

Mozu is obviously very relieved of Momen's excellent technology, and it is not okay if he is not at ease, basically the people of Momen rely on this to eat.

"I don't need to take this exam today." Zhang Nan smiled, and said to Mozu: "Mozu, dare to ask if the model of the steam engine I gave you is still there?" ”

Mo Zu nodded and said, "Naturally, what's wrong?" ”

"Then please Mozu take out the model of the steam engine, today's exam question is related to this steam engine." Zhang Nan said.

When Mo Zu heard that it was related to the steam engine, his heart suddenly became relieved, after all, when the steam car was made, although not everyone in Momen was involved, basically everyone had read the drawings, otherwise the steam car would not have been completed so quickly.

Soon, Mo Zu brought over the model of the steam engine that was placed in his office, which was specially ordered by Mo Zu, so although Mo Zu had never come to the Ministry of Heavenly Engineering, it was still very quick to find something.

Zhang Nan took the model of the steam engine in Mozu's hand, took the steam engine, and began to walk around in front of the people in Momen, saying as he walked: "Everyone, you have all seen this thing. ”

"Yes." All the people in Momen said in unison.

"If you've seen it, the steam car must have come from you." Zhang Nan said with a smile.

The crowd of Momen nodded.

"So it's great, today's exam question is, I want you to independently design a different from the steam car Karakuri, of course, is powered by steam, but it must be different from the steam car, to be different, and this thing must have use value, not the kind of flashy thing, the first thing of the machine is to be able to save time and effort. So this question is left to you, you have two days to think about this problem, I don't ask you to be able to come up with a detailed drawing within two days, as long as you have a general idea, there is a general idea, I will pass the test. Zhang Nan said.

Zhang Nan is naturally not worried about them plagiarizing each other, because in the face of absolute interests, everything is a floating cloud, and this kind of idea is a lot more difficult for them to think, after all, this is a cross-era idea, even the steam car is the idea that Zhang Nan gave them, and they made it, so Zhang Nan is not worried about cheating.

"If you think it's too difficult to redesign a Karakura, it's okay, I'm not such an unkind person, although the steam car looks good, but it has a big safety hazard, you can also choose to solve the safety problem of the steam car, if it can be successfully solved, then you can also pass, by the way, the problem of solving the safety hazard can be done in a group of two people, that is, you can freely combine, as long as it can be solved, the two people pass together." Zhang Nan said.

Zhang Nan felt that his plan was perfect, killing two birds with one stone, not only successfully opening up new ideas for the application of steam engines, but also solving the potential safety hazards of steam vehicles by the way.

Zhang Nan is sure that at least half of the people will choose to solve the security system problem, after all, there is a lot of power in numbers.

"Okay, the deadline is two days later, you can start now, two days later is the time for acceptance, if you pass, then congratulations, successfully obtained the status of a scientific researcher, if you can't answer one of the two exam questions, then I'm sorry, the Ministry of Tiangong is not a welfare institute, you can only rely on yourself to make a living, just like before." Zhang Nan said.

As soon as Zhang Nan finished speaking, everyone in Momen immediately scattered, looking for companions to find companions, looking for companions, bowing their heads and thinking, anyway, they were not idle.

When the Momen people left, Mozu came to Zhang Nan's side with a smile and said, "Qingquan, your method is good, old man, I never expected you to take the exam like this." ”

Zhang Nan smiled and said: "Mozu praises it, in fact, this is just a test of their work ability, a good craftsman, not only to be able to turn imaginary things into reality, but also to be able to think, otherwise Datang's science and technology must be stagnant, only continuous innovation and invention, that is the right direction of science and technology." ”

Mo Zu nodded, agreeing with Zhang Nan's idea very much.

"You're right, the reason why Momen has been weak for so many years is not only that the rulers of a hundred years ago chose Confucianism, but also our Momen family's own self-styled ways, my Momen ancestor Mozi can make wood birds that go around the beam for three days, and now, our Momen doesn't know the principle of ingenuity, and we are really ashamed of the ancestors." Old Mo Zu said with a blushing face.

After hearing this, Zhang Nan wanted to touch Mo Zu's head very much, and said to Mo Zu: "Actually, I don't blame you, if you can understand the internal combustion engine now, it will be good." ”

Zhang Nan didn't stay in the Ministry of Heavenly Work for long, after giving the exam questions to the people in Momen, Zhang Nan left the Ministry of Heavenly Work, and Zhang Nan, who left the Ministry of Heavenly Work, was stealing half a day of leisure, at least now Zhang Nan is to hurry up and be happy, if you wait until the craftsmen from all over the country come, Zhang Nan will be busy.

Zhang Nan chose for a long time, and finally chose to come to the private club to relax, although Zhang Nan also wanted to go to the evil church to listen to the music and see the red light place officially opened by the Tang Dynasty.

But after a strong struggle in Zhang Nan's heart, Zhang Nan finally gave up this idea. After all, Zhang Nan is a representative of thieves who have the heart of a thief but not the courage of a thief, just like Zhang Nan wants to experience the life of three wives and four concubines, but after coming to Datang for so long, Zhang Nan is still only Cui Yue.

After finding a horse, Zhang Nan rode to the mountain, and after a short time, Zhang Nan came to this place called the new generation of gold caves by the upper nobles and businessmen, of course, the previous generation was also opened by Zhang Nan.

Zhang Nan came to the gate, and the waiter standing at the door hurriedly opened the door for Zhang Nan, Zhang Nan was not ambiguous, and went directly to the big hot spring, after all, the cliff hot spring, that is a private club.

After changing into swim trunks, Zhang Nan had just taken off his bath towel and was about to enter the water, when he suddenly found that there was a person floating not far away.
