After finalizing the pay, Roland plans to tear down another wall on the road to great development.

That is the development of standard units.

The popularization education work of Neverwinter has long incorporated the units of distance such as millimeters, centimeters, meters, and kilometers into the teaching materials to replace the original inches, rulers, and zhangs, which is quite effective at present. Especially in the construction and industrial production sectors, measuring instruments made from new units have been widely recognized for their greater accuracy.

The one-centimetre of the fibre, a bar of iron the width of Roland's fingernail, was kept in the castle's study.

The next thing he needs to do is to integrate the other units and promote them to the whole country of Grey Castle.

The reason why this step is being done now is that the previous level of production and education did not urgently require other new units, and second, it is technically difficult to reproduce.

After all, there is no point in having standards, and if they cannot be made into measuring instruments, people will not be able to use them in real life.

But these difficulties are no longer a problem.

For example, a container of cubic decimeters is defined as one liter, and the weight of one liter of water is defined as one kilogram, and the period of a single pendulum one meter long is defined as one second...... The former can use hummingbirds to accurately replicate the original kilogram of equal weight, while the latter can provide timekeeping by means of a pendulum clock. With prototypes and models, Neverwinter's factories can produce a large number of imitations.

Otherwise, it would be a waste of time and energy for Anna to do all the measurement tools alone.

When industrial technology reached a certain level, the popularization of more precise units of measurement became a matter of course.

Nor is he concerned that these standards are not "pure" enough, and in fact, the original instruments used in human history are themselves changing with the progress of the times.

......

Three days later, Iron Axe finally led the Eastern Front Army back to Neverwinter, and at the same time, he arrived with the echo that had been in Bishui Harbor for nearly half a year.

Roland looked at the two sand people who reported to him at his desk, and sighed slightly—both were originally exiled family criminals, one of them lived incognito in a border town and lived by hunting, and the other was sold into slavery and lived a tormented life. But now, they are an integral part of the Neverwinter hierarchy.

Shouldering heavy responsibilities alone, after several months of busy outside, Iron Axe's face did not show the slightest tiredness, but became energetic because of the war, and he already had the style of a general in his gestures. The change in the echo was even more obvious, the shadow caused by her slave life gradually faded, and there was a confident luster in her blue-gray pupils, and her temperament was more and more consistent with her status as the patriarch of Aosha.

Sure enough, experience can change a person the most.

Echo's report was simple, the Flame Clan had fulfilled their promise, and the first group of migrated teams had settled in the Blue Water Harbor. Influenced by the first clan of Iron Sand City, and then a number of small clans approached her and expressed their willingness to serve the big chief, and the whole plan went very smoothly. After receiving the patriarchs of all parties, the relocated population of Bishui Port is expected to reach 30,000 by the end of the year, which is already comparable to the number of people in the old royal capital.

In addition, she also brought a handwritten letter from Speer, the lord of Falling Dragon Ridge, who knew without reading it that she must have come to ask for food.

Speer said that she was only the manager of a small fiefdom and had no experience in caring for so many people, and that she was about to lose her time for a while. Echo mimicked the other man's tone and said, "Although the skilled hands sent by the town hall are easy to use, according to their advice, it will take at least two or three hundred clerks to accommodate such a large number of migrants, and if Your Majesty doesn't take care of her more, she will have the urge to leave her burden and run to Neverwinter to be an ordinary witch." ”

Roland couldn't help but chuckle, Ordinary witches are not the same as idle, Zoroya and Ye Zi are looking at you. If you don't use up your mana every day, how can you be worthy of such a good ability as the mana channel. "I know, the next batch of new officials who pass the review, I will give her more. This mission has worked hard for you, so let's rest for a few days. ”

"Yes. She bowed first, and then spoke expectantly, "By the way, Your Majesty, you have had a ...... lately A new song?"

"Uh, you can sing the ones before?"

"Hmm...... They all work very well, especially when it comes to inspiring people. Echo replied with a smile, "And when I'm confused, I also sing the songs you taught me—if it weren't for those tunes, I'm afraid I wouldn't have made it to this day." ”

It seems that coordinating the relationship between the clans and maintaining order in the south is not as simple as she reported, but she has borne the difficulties and setbacks alone.

"I see," Roland said slowly, "I'll find someone to transcribe the new song and send it to your room." ”

Echo bent down deeply, "Great, thank you!"

Even if he didn't know anything about music, he could go to the dream world to rummage through it, and he couldn't say no to such a request.

After the echo retreated, Roland set his sights on the Iron Axe.

"You've worked hard too. ”

"No, Your Majesty," said the latter, he hurriedly stroked his chest, "it is my duty to fight for you, and not only do I not feel the hardship, but I enjoy it." ”

"Really?" Roland smiled, noncommittal, "What happened to the nobles who fled to Seabreeze? You're not going to burn them all with another fire, are you?"

"I'd love to do that, but it's a pity they're running too fast," Iron Axe said, "By the time the First Army arrived at Haifeng County after clearing Golden Spike City, the outskirts had become a wasteland. Not only that, but there are several granaries in the city that have been set on fire - apparently they would rather destroy the town than leave it in your hands. ”

This was probably the last revenge of the rebel remnants, and he thought to himself that if it weren't for the Eastern Front Army's adequate preparations, and dozens of cement transport ships behind him to provide supplies, he might have to retreat immediately. Otherwise, the city's citizens who were short of food would have taken the First Army as a target for plunder, and once they were shot, it would be difficult to restore order.

"Where did they all flee?"

"Some go to the fjords, and some go to the other three kingdoms," replied Iron Axe, all regretfully, "but it is a pity that the First Army has no ships, otherwise I would never have spared them." ”

"Don't worry, as long as they dare to use their original surnames, I'll get rid of them sooner or later. Roland said slowly. At least the ones who fled to the dawn were no different from the flying insects that threw themselves into the net. This group of people is probably the last diehards of Tifeko, and he is not worried that the other party will be able to make a comeback, and he just thinks they are an eyesore.

After inquiring about the aftermath of the Eastern Territory, Roland suddenly thought of a previous question.

"By the way, trick the nobles into prison and burn them down under the guise of a fire...... Is this the way you figured it out?"

Iron Axe's expression stiffened.
