Silicon.

The atomic number is 14, and the relative atomic mass is 28.0855.

Silicon is an important raw material for the manufacture of integrated circuits.

The development of integrated circuits has promoted the development of space science and technology to a great extent from the side -- at the same time, integrated circuit technology is also an indispensable basic technology for advanced space science and technology.

The amount of silicon reserves is closely related to the development of advanced space navigation technology and the implementation of this technology.

In nature, silicon generally exists in the form of chemical compounds.

For advanced space navigation technology civilization, sand and rocks are an excellent silicon raw material.

However, at present, for the native civilization here, sand is only sand.

......

With a clear blue sky and cloudless skies, this would be especially welcome if not in the desert – however, in the middle of the desert, such weather simply means that it is full of dry heat.

The scorching sun at noon poured the fierce sunlight into the sand without reservation, scorching this vast desert.

The sand dunes in the distance, quivering and twisting under the influence of the air currents, are a unique sight created by the high temperature of the desert floor.

There was no wind around – and even if there was, it was just hot, dry air.

In this barren desert, secret signals similar to white noise are also spreading.

"Sector One, what's going on here?"

"The enemy has appeared, and it is a big threat to the native civilization here, but don't worry, for us, they are just big guys who are technologically backward. We're here and we've made a plan, and it's not going to be hard. ”

"Okay, stay safe. ”

......

Of course, for the Rotiri-Cydili civilization, which has not yet mastered radio technology or even electrical technology, they naturally have no tools to receive it, nor will they receive any so-called "white noise".

On this desert, the slightly tired camels, leaning on the slightly old reins in front and back, are more relaxed, stepping on the hot sand, and marching forward.

There were about twenty of these camels in front and behind – a caravan of goods in the desert.

The kingdom of Rotiriño Sediri is located in a vast desert, and whether it is to conduct business, or to transport supplies, etc., it needs to rely on camel caravans.

This endless desert is like an ocean.

The caravans, on the other hand, walked in the "desert sea" like a fleet of ships – according to the custom of the Cedili caravans of Rotiri, they went from one point to another, usually not in a straight line, but along the "desert routes" that connected the oases - which was time-consuming, but it was safer to keep a closer distance from the oasis.

In front of and behind the caravans, which were connected by a series of reins, were caravan guards of thirty men and horses—the front one to clear the way, and the one behind to follow the guard.

The task of these caravan guards is naturally to escort the merchants, as well as the goods in these caravans, to reach their destination safely - in the desert here, there are many greedy desert marauders, who like to plunder the goods and money of the caravans the most, so they naturally have to guard against them.

The caravan guards here today are a bit large - judging from the number of people, this caravan should be transporting some valuable goods.

"Guys, let's take a break!" the leader of the caravan shouted to everyone here.

"Everyone, get ready to rest and stay vigilant!" the young caravan guard, "Desert Wasteland Blade", shouted to the surrounding caravan guards.

The caravan stopped, and the two caravan escorts, who had been in front of and behind the caravan, led their horses to both sides of the caravan - this was the protective formation during the break.

"It's too hot...... Drink some water......" said one of the caravan guards as he pulled out the kettle hanging from the horses, "On this hot day, just drinking water is a pleasure." ”

"yes...... However, the water is a little hot and sunburned......"

"Okay, okay, don't ask for so much. ”

The caravan moved near the intermittent oasis - so that they could be replenished with water every distance they traveled.

"Wait...... What's that?!" Another caravan guard on the side suddenly became vigilant.

"What's wrong?!" the caravan guard looked in the direction his companion was looking before he could open the jug for water, "Someone!

"Everyone, stay vigilant!" the caravan captain named "Desert Wasteland Blade" immediately reminded the caravan guards on the side.

The caravans, coming from the inland gold mines, were to be transported to towns near the desert oases of the coast, where they could be exchanged for sturdy horses, endurance camels, and, of course, a large number of handicrafts, and all the gold added up to a small building in the city, or, for several limited-edition luxury carriages!

The gold trade from the inland desert to the coastal oasis cities was lucrative – a way to make a fortune if you had the conditions to transport it to the desert and could endure the scorching heat of the desert.

Of course, the predators in the desert know this!

As you navigate the desert, watch out for fierce and greedy marauders.

Since they were escorting valuable goods, these caravan guards were naturally extra vigilant now - even if they only saw someone not far away, and could not confirm whether the other party was a marauder or not, they had to be prepared to defend.

"Hmm...... Those people...... It's starting to turn ...... Their horses are lined up, they should be the same as us, a caravan in the desert!" A caravan guard analyzed, looking into the distance, his tone began to lighten - after all, those people didn't look like some kind of marauders.

"But...... There's something strange about it......" A caravan merchant on the side also looked into the distance, at the strangers.

He was still wary, but in addition to that, there was a suspicion - according to the custom of Rotiri, Sedilri, caravans generally used camels to transport goods, and those strangers used horses—which was more or less strange!

No one knew if they were just caravans, "desert raiders", or some other scheming man.

Of course, whether it was a caravan or something else, at least, it was only familiar to them.

And while they focus on these familiarities, a strangeness carrying fear is quietly approaching.
