In Luo Yi's opinion, it is undoubtedly a good thing to be able to enhance Luo Cheng's prestige through this move.

The most important thing is how to solve this problem. The precedent of the Sui Dynasty is still fresh in his mind, and Luo Yi doesn't want Daxia to repeat the mistakes of the past, so he must change it.

In this regard, Luo Cheng already had a preliminary idea, that is, to discuss it carefully with Luo Yi, and both of them thought so.

Then Luo Cheng arched his hand and said: "Now that the time has entered autumn, I'm afraid it's too late to go to the place again, it's better to wait until the beginning of spring next year, and then do this, don't be too aggressive, and be slowly."

After a little mover, Luo Yi nodded slightly and said: "It's okay, now that Cheng'er has just returned from Goguryeo, let's go back and rest for some time first, and leave this matter until next year to discuss it, it's not too late."

At this point, Luo Cheng bowed and retreated.

……

The trip to Goguryeo did not cause much trouble.

But this long journey is a little tiring after all.

Therefore, Luo Cheng cultivated well in the mansion for a few days, and he also kept warm with Xinyue'e. It has been a while since she got married, but she has not yet conceived an heir, and Xinyue'e is still a little anxious.

Luo Cheng wasn't too worried, after all, he still knew it very well, but he was only about twenty years old. In the next life, he is just a college student, where is the use of worrying about this?

But now the times are different after all, so Luo Cheng let it go.

After that, Luo Cheng suddenly got a notice from Huba that the steam engine he had been researching had made progress again.

This matter was originally led by Luo Cheng, but with Huba joining later, Luo Cheng entrusted this matter to him. Although he didn't have a lot of knowledge that Luo Cheng mastered, he also mastered a lot of things after studying.

But Huba said that the research had progressed, and Luo Cheng was still a little surprised, after all, this thing was very important. Today's technology is still not very good at manufacturing things such as internal combustion engines, and you can only start with steam engines.

Starting from the power aspect, promote the transformation and renewal of various places, and only in this way can this ancient country be transformed in a short period of time, Luo Cheng does not want to wait for him to die of old age.

This is a very real problem, if the final metamorphosis is not completed. The successor does not have Luo Cheng's plug-in, so he naturally cannot continue to advance, and may even regress because of the sequelae that occurred before.

So after learning the news, Luo Cheng hurriedly went to the workshop, and he also wanted to see what kind of results Huba had made. If a full-fledged steam engine were to be built, the change would undoubtedly be enormous.

In the case of trains alone, stability and speed can enhance communication between territories. And it can transport a large amount of heavy grain and grass, making it easier for the army to conquer, and it is a magic weapon for Luo Cheng to go further in the future.

And as a machine, the steam engine is not limited to energy, as long as coal is transported, it can continue to work. This kind of efficiency is extremely terrifying, and it can promote the development of society more quickly.

After a while, Luo Cheng arrived at the workshop, and the guards saw Luo Cheng and hurriedly took him in. In fact, Huba has been waiting for a long time, just waiting for Luo Cheng to come and watch.

"I've seen the prince in my humble position." Hu Ba and the others saluted Luo Cheng one after another, they worked and studied here, and from a certain point of view, they could be regarded as Luo Cheng's subordinates, and even incumbents.

Luo Cheng didn't care about this, he nodded slightly to let everyone get up, and said loudly: "Huba, I heard the news that you sent someone, has the wooden cow and the horse really made progress?"

In this matter, Huba was not ambiguous, nodded and said: "Yes, the humble post sent someone to inform the prince, it is precisely because of the wooden ox and flowing horse, now that the finished product has been manufactured, the prince can go and have a look."

This is a steam engine, and compared to the previous prototype, it is undoubtedly very well built. Just looking at the appearance, there is a great change, and it is not installed elsewhere at the moment, just a single existence.

Luo Cheng knew that Huba didn't want him to see the cool appearance of the steam engine, since there was progress, there must be a certain degree of progress in power or stability.

Sure enough, Huba was soon on display, and as the ignition started, the new steam engine was quickly up and running, making a rumbling sound, and the many joints on it began to conduct.

As far as Luo Cheng can see, this new type of steam engine has really changed a lot. Fang Cai's operation has stabilized a lot, and although no other equipment has been added, a noticeable improvement can be seen in terms of speed.

Luo Cheng nodded, satisfied in his heart, and said, "It seems that you have indeed not slackened during this time, but after this thing is installed, can you maintain such a rate?"

Hearing Luo Cheng's question, Huba seemed very determined, his tone was confident, and he replied: "I have already done this test before, and the speed is enough to compare with ordinary horses, and most importantly, this speed can be maintained for a long time."

This is good news, Luo Cheng thinks so, this shows that the steam engine has met the requirements, as long as Luo Cheng is willing, he can start laying railways at any time, and even use the steam engine in other industries.

As in the textile industry, the addition of a steam engine is bound to work wonders. But this is a later story, Luo Cheng is still ready to solve the traffic problem first, and the impact is also not small.

For the traditional Chinese people, the sudden appearance of the steam engine is a bit shocking after all. Although everyone is quite receptive, it must be done gradually.

Therefore, Luo Cheng knew that if he really wanted to build railways and trains, he had to find a place to pilot them, and then gradually promote them at that time. And this pilot place, Xia Jing is a good place.

But there is no need to worry, Luo Cheng still has a lot of time, looking at this new steam engine, Luo Cheng asked with some doubts: "How long did it take to manufacture this wooden ox and flowing horse?"

Speaking of this, Huba was a little embarrassed, and he said with a slightly helpless expression: "Although this thing has been improved a lot compared to before, the process is also much stricter, and I am afraid it will be difficult to mass-produce."

Talking about this, Luo Cheng understood Huba's difficulties, because to make a more advanced steam engine, the requirements for itself will be higher, even if the parts are the same.

Therefore, the success of building a steam engine will inevitably increase a lot, and most importantly, it will be difficult to popularize. What takes an extremely long time to make will eventually become a luxury.

However, Luo Cheng didn't want to do this, if he wanted to solve this problem, he had to make the lathe out. A standardized and reasonable manufacturing process can greatly improve efficiency.

Luo Cheng had similar thoughts before, and now the problem Huba is facing is undoubtedly waking him up. Some things have to be done after all, and this is an extremely important part of the technology tree.
