In the days that followed, the 8,000 students fell into the fact that the locomotive was too heavy for the power of the steam engine to be able to carry the locomotive, and that the steam engine was too big for the structure to support, and the locomotive began to grow in size......

Half a month later, seeing that the locomotive was half the size of the yard, Ren Baqian finally couldn't help it: "Can't you idiots replace the structure with iron?"

"Iron is too expensive! I can't afford it!" said Tonglan with a small face, and everyone nodded.

Ren Baqian almost laughed angrily, a group of officials and the second generation...... Well, although it's a waste firewood in the second generation of officials, it's a lot of money, right?

However, seeing that their expressions didn't look fake, Ren Baqian remembered that he hadn't cared too much about Da Yao's current iron production these days, so he didn't say more.

Not enough, he has recently discovered some interesting phenomena: in the past, it was okay, that is, starting with the construction of steam engines, these students gradually divided into three levels.

The first level is Tonglan and Shi Kang, the two with the highest force, and it can be seen from the two of them at this time: the other people's bodies are a little dirty, but the two are relatively clean.

However, the cleanliness of the two is not the same, Tonglan is clean and refreshing, and she is dressed in white clothes, which is completely incompatible with the messy scene around her.

And Shi Dare ...... Although his chest and sleeves look a little dirty, you can see by looking at his hands, they are clean and there is no trace of work.

However, he stained his clothes a little bit, making him look less special.

can only be said to be worthy of being the son of the great deacon, and Tonglan, the stupid girl with a head full of muscles, is not at the same level at all.

These two people are mainly responsible for moving their mouths and giving advice. Among them, Shi Kang still put forward a lot of useful suggestions, and Tonglan's role is only to move his mouth and be a mascot.

Although Tonglan seems to have done a lot of things recently, these things are all because of "different ideas" and fighting with Shi Dang, as well as bad ideas.

The second part is a small group of people with higher force, who do less work, mainly doing chores and coming up with ideas. Unexpectedly, this part of the population is mainly civilian students.

These people are still working hard, and their personal strength is not bad, and their performance is generally very good after entering Ren Baqian's academy by mistake.

The last part is the waste wood in the various families headed by Du Laoliu and others, and one by one they are dirty and completely reduced to coolies.

The ancient people's martial arts are respected, the weak eat the strong, and the red fruit is manifested here.

However, this kind of division, Ren Baqian doesn't feel too bad, at least it's much better than the coolies are all civilian children. Da Yao's atmosphere is still relatively simple in the end.

After class, I went to the Ministry of Engineering to inquire.

As a result, I asked and found that these students really couldn't afford it...... It's not fake, it's true.

Although Dayao's Damo iron ore has been mining smoothly for more than half a year, Dayao's iron production has soared, but the price has not fallen much.

It's really that Da Yao's demand for iron is too great.

Although there is a lot of iron ore in Damoshan today, it is still a priority to satisfy the army, and during the war, the consumption of weapons has always been very fast.

And there are also weapons that the militia groups need, which is also a large sum.

After removing these two items, there are not so many parts that go to the people.

After all, it has only been more than half a year since the Damoshan Iron Mine was mined with a solar furnace, and it was only one million catties of iron when it was full, and it was only about 50,000 weapons to build. Although it is a hundred times faster than before, the time is still too short.

Now there are more civilian weapons than before, but they are mainly concentrated in the north, and those weapons left over from the original Great Xia are mainly smelted and built.

Therefore, the price of iron is still at a very high price, and it is only slightly lower than it was at the beginning.

It's okay to let these students scrape together the money to buy two weapons or something, but don't think about the rest.

A pound of iron costs about four taels of silver, and even a steam engine with various structures, connecting rods and wheels costs at least a thousand catties of iron, that is, four thousand taels of silver.

Although most of these students are from good backgrounds, firstly, the wealth of the ancient clan officials is not high, and secondly, most of these students are "wasted" who are not very popular in the family, and there is not much money. Therefore, they really can't afford four thousand taels of silver.

Seeing that Ren Baqian returned to the palace and found that the empress specially transferred 3,000 catties of iron to the Zizhu Academy, and ordered the Ministry of Industry to transfer a few blacksmiths to the past, and separated a courtyard in a corner of the school, which was knocked and beaten there after school at noon every day, and finally put the production of the locomotive on the right track again.

In fact, as long as this thing solves the power problem and has a clear goal, it is not too difficult to complete, but it depends on how much time can be used to research the appropriate architecture, so as to create this locomotive with a low conversion rate to outrageous and ugly ecstasy.

Although Ren Baqian had a complete train drawing of the early 20th century in his hand, he didn't plan to take it out, and the gains from letting the students make a little progress there were much more valuable than a train.

Ren Baqian has been quietly watching their changes, waiting for the day when they transform.

The life of Ren 8000 per day has also become his long-awaited two points and one line, the palace and the academy.

In addition to classes every day, he practiced in the palace, and he had to be repaired by Lori every once in a while. Other times, he sat in a daze with the empress in the palace, or walked around the palace to see some subtle changes in the palace.

For example, street lamps can be seen everywhere.

In the past few months since he returned to Lancheng, Ren Baqian began to carry out his "Palace Lighting Project" again, and when he had nothing to do, he came back with some street lighting equipment and batteries.

Over the past few months, there are now street lamps every twenty meters in the palace, making the palace lit up all night, like a city that never sleeps.

The empress was extremely pleased with such a change, and when she had nothing to do, she would always sit on the roof of the dormitory and drink at night, and as far as the eye could see, there was a bright palace.

At the same time, such a change made the guards and maids in the palace a little unaccustomed, and there was no need for torches or palace lights at night, as if the palace had suddenly become a city that never sleeps in a few months, and there was no dark place day or night.

Even in other parts of Arashijo, you can see the exceptionally bright Imperial Palace at night.

The biggest impact on them is ...... Can't find a place to urinate in the open...... It's too bright......

After all, in a brightly lit place, it takes courage to urinate everywhere in full view......

Also amazed by the dramatic changes in the Imperial Palace were the ministers of the DPRK and China. At the earliest time, they found the street lamps in the palace, after all, there were so many pillars and pestles on both sides of the road, and they couldn't see them if they wanted to.

It's just that the number was still small at that time, and with the ensuing battle with Great Xia and the land of peaceful Tianjing, Ren Baqian and His Majesty were not in the palace, leaving them to secretly speculate in Lancheng.

But no matter how you guess, one thing everyone can be sure of is that this kind of treasure that absorbs light during the day and releases it at night must be very valuable.

Unexpectedly, within a few months of His Majesty and Ren Baqian coming back, the palace was covered with this kind of treasure, so that there were no dead ends in the palace, although it was extremely beautiful, but it also made many people even more frightened, so many treasures, how much did they cost, and where did they get it from.

In addition, there was still a battle in the northeast and southeast outside, but such a change suddenly occurred in the palace, which caused a lot of criticism.

In fact, not only that, but the windows of many palaces in the palace were also replaced with glass, but everyone knew that the glass was made by the royal family, and although it was expensive, it did not cause much discussion.

On the contrary, these street lamps are more precious treasures than night pearls in the eyes of many people. After all, how much light is there in the Night Pearl, and how can it compare to these street lamps in the palace?

This made many ministers privately discuss: Your Majesty has changed a little, and has become too extravagant!

And the source of this change is also inseparable from the governor of Zizhu Academy.
