[The magic crystal is a godsend, which can relieve the people's suffering, but it is not easy to get it, prompting the capable to become the darling of the sky.

After the opening of Vladivostok in 492, four seas were gradually divided according to the city-state, and the crystal nuclei exported were several times that of before. ]

'Trade? Su Xiaoting's heart suddenly sudden. I searched back and forth, but still didn't find a trade partner.

After a moment of contemplation, she muttered, 'Could it be that the Boundless Land and foreign countries, even the United States, are still privately trading in the sale of crystal nuclei? ’

I have to say that this possibility is very high, so as to explain that in Mu Ling, where the level of civilization is so low, many items beyond the ability of science and technology can be seen, including medicines and electrical appliances.

The acquisition of crystal nuclei mainly depends on the capable.

And the United States may not want to serve in the Pure Sea Force, and the ships only dare to patrol the coastal waters, plus the high pensions. On the whole, in terms of the acquisition of crystal nuclei, it is not much lower than the cost of Boundless.

If this is the case, then the relationship between the two sides is somewhat complicated, mutually exclusive and mutually needy, but it is not known whether this trade is officially acquiesced or a dark line established by a few speculative businessmen.

Su Xiaoting pressed down a little taunt and looked at it again.

————————————

High above the Goddess Peak, on the temple terrace, a black shadow flew towards the white shadow on the terrace—

Ji Yingxue gently lifted her wrist, let the tired carrier pigeon land on the wrist guard, and then gracefully removed the letter box from the carrier pigeon's leggings.

Seeing the paper rolled in it, he patted the black pigeon lovingly, put it on the stand next to it to eat, and turned around and walked to the dormitory.

As one of the high priests, Ji Yingxue's palace is elegant and solemn, and in the spacious bedroom, the marble pillars are carved with intricate patterns, the veil is overhanging, and there is a beautiful ivory harp next to the bed.

"Brother is back?"

Before the smile could be withdrawn, a touch of surprise welled up on Ji Yingxue's flower-like smile.

"Bought back the best girl? I also became an acolyte! …… Brother, what do you mean by this? ”

Ji Yingxue looked at the paper scroll in the palm of her hand twice repeatedly, her eyes lingered on the word 'An Ting' for a long time, and she couldn't help but shake a gentle and beautiful face in her mind.

She shook her head, lifted the cascading petal-like skirt, and spun it to the marble table beside her.

A quarter of an hour later, the black carrier pigeon was again plunged into the pitch black night.

——

After a few days of getting along, Su Xiaoting found that she was still too taken for granted before~

In her understanding, if someone is in command of a city-state with a population of millions, a wise city lord should manage every day, have endless meetings with the deployment, and make endless decisions on important matters.

The dim-witted city lord may not ask about political affairs and do not investigate the people's suffering. Indulge in extravagant pleasures and indulge in sensuality every day.

Her positioning of Ji Yuning is naturally the former, but the city lord of Ji can always surprise.

Of course, Ji Yuning will not be a lord who is greedy for pleasure, but it is very different from what she imagined.

In addition to paying attention to medical care and people's livelihood, Ji Yuning seems to rarely deal with political affairs, and it seems that it is a group of civilian personnel who maintain the operation of Fuyao and even Mu Ling.

He seems to prefer to personally understand the situation on the front line, often making decisions on the spot after discussing with the relevant person in charge, and understanding the needs and progress.

So in the next few days, I basically accompanied Ji Yuning to inspect various places in the morning.

There are iron mines, schools, orphanages, and today's electrical research institutes. The group drove directly to the R&D laboratory.

When Su Xiaoting saw the circuit simulators that she was quite familiar with in college on the big long table, she unconsciously opened her mouth wide.

"You've seen it?" There was both doubt and affirmation in the tone.

Su Xiaoting hurriedly closed her mouth and thought about how to answer.

But I heard Ji Yuning laugh as if he was self-denying: "I'm afraid these have long been extinct before the dark age~"

Su Xiaoting was silent, she really didn't have the opportunity to see these electronic devices again in the United States, because the button core of the United States has been able to synthesize hundreds of layers of nano and microcircuits into a button-sized sheet, and several can be loaded in one bracelet.

But no matter how small and subtle it is, the most basic physics is still the same as the circuit board that has been eliminated in modern times. It's just 1,000 times bigger than Newcore......

But ~ what's the point of doing that?

Could it be that because he couldn't import music players from the United States, Mu Ling planned to start from scratch and develop an ancient dual-card tape recorder?

Su Xiaoting's hand stroked the familiar soldering bulge on the circuit line, and couldn't help but murmur: "Does it make sense to do this?!" ”

If you really want to catch up with future technology in this way, will it take a dark time?

Ji Yuning's eyes couldn't help but be slightly surprised, realizing that the other party not only knew this, but also sensed their intentions.

"What's the point? City Lord, Tian is here~" One of them hurriedly walked in with a thin uncle like a bamboo pole.

"City Lord, you're here!" The person who seemed to be in charge did not seem too surprised, but directly introduced the current scientific research progress.

A small set of sound playback experiments was also shown.

"City Lord, the current experimental progress has been completed as scheduled, and the goal of the next quarter is to find a miniature capacitor to realize the modularization of the circuit."

The middle-aged man pointed to a device the size of a date on the table, and his voice lowered, "However, we have not found any literature on microcapacitor materials, the current capacitor volume is too large, the cost is high, and the working temperature can only reach below 55 °C." ”

Su Xiaoting looked at the huge and complex capacitor, and the earthy yellow capacitor the size of a snap button in the circuit class came to her mind. In her memory, even such capacitors were quickly replaced by army-green circuit boards.

The lab was silent, and a few researchers were as quiet as air, except for the person in charge to report on.

"According to your requirements, there are only 2 options at present, first, continue the research and development, but the cycle may be extended to one year, and second, you still have to continue to search for information there, or find relevant professionals."

Ji Yuning replied affirmatively: "It is not easy to find professionals in this area, and our people have been collecting basic scientific and technological literature. ”

"In other words, the only thing you can rely on is yourself~ According to the first plan, what else do you need?"

"Yes, City Lord! We considered using ceramics as insulators, but the price was too expensive, and I was afraid that we would not be able to mass-produce them in the future. ”

"No more alternative materials?"

"Not found yet."

Ceramic capacitors, Su Xiaoting on the side sounds very familiar, she completed a holiday homework in college has a research on capacitor materials, and there is still a certain accumulation of this.
