25.

With an appreciative gaze, the old man stared at Cheng Li carefully for a while before looking at Fang Xiaochun.

Then he looked at Fang Xiaochun with doting eyes for a while, but Fang Xiaochun was still expressionless.

After a while, he coughed a little embarrassedly and said, "Xiaochun, you are still the same, I told you, don't keep your face tight all day long, be close to people." ”

"Nope. Fang Xiaochun said succinctly.

Even if the old man stroked his forehead, he looked a little headache, but he was obviously very doting on his most beloved granddaughter, and he didn't reprimand her much, but stepped forward and rubbed her little head with his big hand.

And although Fang Xiaochun was expressionless and indifferent, he didn't resist when he was rubbing his little head.

After a while, the old man stood in front of the two of them again, coughed lightly and said, "Okay, you two, one is my granddaughter, and the other is the person I am most optimistic about." They are not outsiders, and there are some things that I can tell you separately. ”

Counting the old man said this, which made Cheng Li feel flattered, and the old man seemed to see what Cheng Li was thinking, and said: "Cheng Li, you don't need to be nervous. I can feel your talent through your test papers, you are the best person I have ever seen in yin-yang arithmetic. So, I have high hopes for you. ”

The old man paused and continued: "Actually, what I just said to them is just to stabilize the army's heart, in fact, it is not easy to crack the core secret pattern set of the spirit armor." ”

Cheng Li heard the old man sigh like this, and couldn't help asking, "What is the core secret pattern set of the spirit armor?"

The old man knew that Cheng Li was a foreigner, and he didn't know much about some of the secrets of Qingling Island, so he patiently explained.

"It's a long story. ”

"8,000 years ago, the first generation of my Qingling Island's ancestor [Foreign Daoist] created the yin-yang arithmetic system, and combined with the spirit armor, led my Qingling Island to embark on a completely different path of cultivation.

"The reason why the spirit armor can be driven is because of the [Core Secret Pattern Collection] inherited by foreign Daoists. ”

"This core secret pattern collection is the foreign Taoist himself, who used his supreme wisdom to compile the infinite changes of the yin and yang hexagram and integrate it into a special spirit stone. ”

After speaking, the old man took out a hexagonal spirit stone with a very regular shape.

Then the old man pointed to this hexagonal spirit stone and said, "This is a storage spirit stone, an artificial spirit stone. Most of the spirit stones store natural spiritual power in them, and they do not contain yin and yang changes.

"If you exhaust the spiritual power of a natural spirit stone, you will get an ethereal spirit stone.

"In the past, the Ethereal Stone was a completely discarded thing, but the Outer Dao people have found a way to allow the Ethereal Stone to store spiritual power again. ”

So, through a special method, the yin and yang changes we had written were re-stored in an ethereal stone. This ethereal spirit stone will contain the yin and yang change information that we have written, and then encapsulate it, we will get a storage spirit stone that stores the yin and yang change information we have written!"

Cheng Li immediately understood that this stored spirit stone was equivalent to a USB flash drive!

"After the foreign Daoist stored the [Core Secret Pattern Collection] he compiled into the spirit stone, and after encapsulating it, it became a storage spirit stone, and it was the most special storage spirit stone. ”

"We call this kind of storage spirit stone that stores the core secret pattern set as the bottom spirit stone. ”

"The bottom spirit stone is the lowest foundation of the spirit armor driving exercise. On this low-level spirit stone, the foreign Taoist has many yin and yang mouths. Compared with the complex and mysterious yin and yang changes inside the underlying spirit stone, the yin and yang mouth on the outside is much simpler. We can use the instructions set in advance by foreign Taoists to call these yin and yang mouths to achieve the effect we want. For example, make calculators. ”

After finishing speaking, the old man took out another spirit stone, and then used his fingers to shoot out a fine spiritual light, which was on the spirit stone, etching out a series of spirit patterns.

After a while, the old man connected the spirit stone covered with spirit patterns with the hexagonal bottom spirit stone.

In an instant, the two spirit stones emitted a hazy light.

Then, a light curtain was activated from the Spirit Pattern Stone, and there were several square areas on the light curtain.

"It's the simplest of calculators. ”

As he spoke, he wrote down a number in each square area on the light curtain.

"One, three, nineteen. ”

"Okay, let's just those three numbers. ”

Then he pressed lightly on the Spirit Pattern Stone, and another light curtain was excited from the Spirit Pattern Stone, and at this moment, this light curtain only displayed a number.

"Twenty-three. ”

Cheng Li suddenly came to his senses, it turned out that this spirit pattern stone that had just been inscribed with a spirit pattern by the old man was an addition machine.

As long as you fill in the numbers in each block, the Spirit Stone will add up the numbers in all the blocks to get a sum.

"Yes, this is the easiest calculator to do summations. If necessary, we can also make some more complex calculators to do more complex calculations. ”

When Cheng Li heard this, he couldn't help but ask: "Count the old, what is the operating principle of this calculator?"

Counting the old man, he couldn't help but smile bitterly: "Actually, we don't know what the operating principle of this calculator is." ”

"The spirit pattern on our inscription is just a call to the ready-made yin and yang mouth on the underlying spirit stone, and the actual operating principle is hidden in this underlying spirit stone. ”

"We input information, call the yin and yang of the underlying spirit stone through the spirit pattern stone, and then calculate the internal calculation of the underlying spirit stone, and then output the result and present it to us. ”

"Throughout the process, we all invoked these Yin Yang Kou according to the instructions set by the foreign Dao people, but we didn't know anything about how to calculate this information inside the underlying spirit stone. ”

Cheng Li immediately understood that if you use modern language, this low-level spirit stone is, to put it bluntly, the lowest-level machine language code that integrates the instruction set!

After writing down the instruction set of the Spirit Armor Driver, and encapsulating it, it provided many interfaces. In the words of the cultivators, these interfaces are the yin and yang mouths.

Then, the people on Qingling Island can only call interface commands on these ready-made interfaces to achieve the effect they want.

It's the equivalent of programming in assembly language.

However, they didn't understand the specific operation principle of the internal instruction set of the underlying spirit stone.

As a result, the underlying spirit stone was like a black box. For the people of Qingling Island, they don't need to know the structure and operation principle of the black box, how to call the interface provided by the black box, and achieve the results they want.

For example, almost everyone on the earth can play with mobile phones and computers, but few people know the inner workings and operating principles of computers and mobile phones.

The computer and the mobile phone are the black box. And the underlying spirit stone on Qingling Island is also such a black box.

In this way, although the people of Qingling Island can use these low-level spirit stones to carry out assembly language programming, they also lose the possibility of improving these low-level spirit stones.
