After discussing Jia Yi's sonar technology, they each finally bought one, although the effect was weaker, but it could also make up for the lack of active detection methods of their low-level mages, Jia Yi was originally aiming for this. In addition, Jiayi gave a big discount, and if they made it themselves, it wouldn't be cheaper, and it would take a lot of time.

Then we talked about Jiayi's grandfather clock, although in fact, Jiayi's fountain pen should be more popular, except for some old-fashioned ones, Jiayi's fountain pen has undertaken most of the writing work. Especially after the emergence of fountain pens that can store ink, basically every mage and every nobleman will carry one with them, and Jiayi is ready to launch luxury brand fountain pens, ready to earn greater benefits.

However, the mage's dipping pen also accounts for a large part, because the ink used to copy scrolls and depict runes has many ingredients in it, many of which cannot be completely dissolved, and it is not easy to block with a dipping pen.

Probably because fountain pens are still too small, so although fountain pens have almost replaced the position of quills in most of the more prosperous areas, they are not as famous as table clocks. The advent of the table clock has almost completely replaced the old way of keeping time, and even people's schedules have changed differently.

March looked at the various table clocks on display at the counter, and the girl's heart was completely stimulated: "Jiayi, you have a lot of clock styles here, I can't compare to the ones I've seen before, and this, it's so small." ”

March is talking about a very small wall clock, only the size of a bowl, and with bright decorations, it looks small and cute. This was originally what Jia Yi wanted to make smaller, so that he could carry it with him, but he forgot one thing, the clock is different from the watch, the clock is timed by a single pendulum, and the most important point of the single pendulum is that it can't shake, and if it moves, it's not allowed, so it's not something to carry around.

Kaichi told them about his original plan, and said with pity, "If only I could have a clock to carry with me." ”

"Hey, you said, if there is a storage ring, put the grandfather clock in the storage ring, isn't it good, the space inside the ring has been relatively static, even if the heel bucket outside has no effect. Chester said with his whimsy.

Jia Yi was about to refute when he heard this, but March hurriedly said: "Are you stupid, the table clock is related to gravity, and the gravity inside the ring is the same as the outside?"

Chester actually sensed that something was wrong after he finished speaking, he was also a formal mage, and he also knew about the table clock, but he didn't speak through his brain, so he made such a low-level joke, and now he was speechless by March. At this time, people are still very simple, if they make mistakes, the first time is to reflect and avoid making mistakes again. Unlike modern people, the first time is to cover up, especially the officials of country Z, who are banned and deleted at every turn.

Chester made an apologetic gesture and stepped back from speaking.

Jiayi said: "The main thing is to have something that can have a stable time period that is not affected by the outside world, otherwise there is no way to carry it with you." And according to the theory of Lord Isaac, the planet under our feet is round, and the gravity is different at different latitudes, so the length of the pendulum is also different. So..."

"So, when the grandfather clock goes somewhere else, it becomes inaccurate. Jade continued.

Jia Yi actually knows what the principle of the watch is, it is a hairspring, but what the hairspring is, he doesn't know, he has dismantled the alarm clock before, there is a thin small coil that has been swinging, he can't understand the principle of this thing at all, if you don't know the clockwork, you will think this is a clockwork.

Therefore, although he has always wanted to make a watch, he has never been able to achieve it.

"And the time of 12 o'clock in each place is actually different, maybe 12 o'clock here is only 10 o'clock in the westernmost part of the empire. Ma Duo also said. I didn't think it was dark before, but now that the pendulum clock has appeared, these problems have also appeared.

There is no news network in this world that tells the time on the hour, so if you want to calibrate the time of the pendulum clock, it is still based on the sundial, and the sundial at 12 o'clock is the most obvious. And if you follow the sundial, every thousands of miles of longitude, the difference between the time before and after is still obvious. In fact, this problem has long been discovered by the Supreme Council, but it was originally based on the sundial to determine the time, so it is difficult to unify the time, and now with the pendulum clock, there is a unified basis.

It's just that the pendulum clock has not been launched for a few years, although some people have realized it, but probably the legendary mages of the Supreme Council have a long lifespan, resulting in a different concept of time, so no specific solution has been introduced.

Perhaps, it will also be divided into time zones.

While they were talking, it was just 12 o'clock at noon, and several pendulum clocks with the function of striking the time rang together, there were jingling bells, there were cuckoo sounds, and music sounds, and there were little people dancing in the pendulum clocks, cranes and birds flapping their wings, and in an instant the whole hall seemed to become a vegetable market, which was very lively.

"Wow, it's hilarious. Ma Duo plucked his ears, "This is too much and too noisy, doesn't it seem to be noisy?"

"These are called self-striking clocks, and they will tell the time on the hour, and twelve o'clock will be like this, because here they are for display, so there is no cancellation of the function of telling the time. Jiayi introduced that the hourly chime function of each clock can be canceled, after all, some people like to be quiet.

In order to ensure that all the clocks are consistent, the people in the Chamber of Commerce spend a lot of time every day calibrating the clocks in the exhibition hall to make sure that there is no more than 20 seconds apart.

There are many bells ringing together, and it's really too noisy, and if it's one, it's funny, but too much and too miscellaneous is a kind of torture. They couldn't stand it and ran out as if they were running away, no wonder they couldn't see anyone in the exhibition hall at this time, they probably all hid out.

After going out, they were almost out of time, so they found a restaurant recommended by Jiayi and started eating.

Although Jiayi's craftsmanship can be said to be better than most restaurants, and the means of cooking are more abundant, Jiayi does not feel that all local food is useless, and each place has its own characteristics. So when he doesn't go to a place, he will try the local specialties.

However, at this time, the cooking methods are indeed relatively poor, and most of the special foods are roasted or stewed, but the ingredients are unique to the local area, and there are some special seasonings. However, the imperial capital is more special, because people from all over the country gather here, and they also bring different food styles from all over the country, blending with each other to form a unique style. Even from Jiayi's point of view, I think many dishes are very good.

After lunch, Kaichi took them to the sauce garden under construction, where many seasonings will be produced, such as vinegar, soy sauce, soybean paste, bean paste, noodle sauce, and even chili sauce, meat sauce, etc., in short, all the sauces that Jiayi can come up with and know how to make it will be made. In addition to sauces, there are also spices that Kaichi has found, which are also processed here, made into powders, or cleaned.

Speaking of which, Eunice is also interesting enough to Jiayi, just because Jiayi likes it, they built this sauce garden for him, specifically to provide seasoning support for Jiayi. They and Jia Yi are partners, not Jia Yi's subordinates, so it is very rare to treat Jia Yi like this.

It's like a company nowadays that deliberately builds a Michelin-level restaurant for an engineer, unless the engineer is called Twist Vine.
