13.

Early the next morning, Cheng Li got up and came to the Qingling Academy to continue attending his own classes.

According to the arrangement he received yesterday, there are two classes today.

One is the yin-yang arithmetic class in the morning, and the spiritual armor knowledge class in the afternoon.

As far as Cheng Li knew, Yin Yang arithmetic and spirit armor knowledge were originally courses that would only be learned when they had been promoted to the leaf level.

However, because Qingling Island plans to hold a yin-yang arithmetic competition for the whole island tomorrow, it has specially opened a course on yin-yang arithmetic and spiritual armor for everyone today, which is equivalent to a universal nature.

For Yin-Yang Arithmetic and Lingjia, these two are what Cheng Li is most interested in, so he went to a school specially used to give lectures in the Qingling Academy early in the morning to prepare to listen to the lectures.

This is a building with more than ten floors of ancient pavilion style, surrounded by aura, as if in a fairyland.

Just as Cheng Li was about to walk into this school, he suddenly heard an incomparably loud bell.

"This is a war mobilization order! Once it rings, it means that our Qingling Island is facing a moment of life and death!"

The people around suddenly let out an exclamation, and Cheng Li roughly understood what was going on.

It seems that this is the beginning of the war mobilization of the high-level of Qingling Island.

Sure enough, immediately after, Cheng Li saw a huge projection as high as a hundred feet, which was mapped into the air, and everyone on the island could see this magnificent figure.

This figure is the head of Qingling Island - Tuomu Zhenren!

"All the people of Qingling Island ......"

The projection of Tuomu's real person in mid-air slowly sounded, full of murderous intent.

"Now our Qingling Island is once again facing a moment of life and death.

"Blood Demon Island is about to attack our Qingling Island in a big way during this intermission of fog, and it is expected to be there in another ten days!"

"And this time the misty route has also been upgraded, and we will face the army of the demon clan led by the five-rank demon monarch!"

When everyone around heard this, they all exclaimed, the news of the attack on Blood Demon Island before was only circulating at the top level, and now it is the first time that the whole island has been reported.

And as soon as everyone heard the Five Rank Demon Monarch, their faces were pale and their faces were terrified.

This time, the demon clan army is led by the five-rank demon monarch, and such a thing can't be concealed at all, and as soon as the war starts, everyone will be able to see the world-beating power of the five-grade demon monarch.

Rather than hide until that time, let everyone be shaken.

It's better to talk about things now, so that everyone has the consciousness of breaking the kettle.

So the head of the sect, Tuomu Zhenren, continued to speak in a voice full of iron will.

"Ten thousand years ago, Shenzhou was shattered for nine days, and we entered an isolated island era.

"Two thousand years ago, the appearance of intermittent periods of fog storms made it possible for the isolated island to regain contact, but it opened up darkness. ”

"The Great Dark Ages of a thousand years ago proved that all islands but ourselves cannot be trusted.

"In this fog, we are isolated from the world, and within this isolated island, we can only believe in ourselves!

"Over the past thousands of years, we have faced countless wars on Qingling Island, and we have never been afraid of war!

"The blood of the martyrs has long built the iron-blooded will of our Qingling Island!

"In the face of a strong enemy, we can only fight to the death!"

When the words fell, the whole island invariably issued a call for "fighting to the death" from all over the island.

This cry was like a tsunami from all corners of the island, and it rose into the sky!

"Fight to the death!"

Listening to the extremely passionate shouts of the people around him, Cheng Li's face also had a trace of solemnity.

"It seems that if you want to go home, you must first survive. Cheng Li thought in his heart.

After understanding these days, he also knows a lot of things. Including the person with the highest cultivation on Qingling Island, but the person who is in the infancy, and the cultivation corresponding to the demon clan is the four-grade demon king.

And when he arrived at Qingling Island on the first day, he heard Ye Lin and Huo Wu's words in the forest, and knew that this attack on Qingling Island by the Blood Demon Island was led by the Five Rank Demon Monarch.

"I'm afraid this battle is not good, I have to find a way. This is a war between races, and if it doesn't stop, I can only find a way to let Qingling Island win. But what can I do, a first-grade Qi Refining Stage cultivator who has just cultivated......

With these thoughts, Cheng Li stepped into the school.

......

On this day, Cheng Li was hungry and thirsty to absorb the knowledge of yin-yang arithmetic and spirit armor on Qingling Island.

With the vision of modern people, standing on the theoretical platform built by countless scientific giants on the earth, Cheng Li has a vision beyond this era to re-examine these theories of cultivation.

What's more, Cheng Li was an extremely good programmer in the original world, and when he used the thinking logic of a programmer to re-understand these theories of cultivation, he found many similarities.

"I understand that this yin-yang arithmetic is actually a discipline that studies binary languages. It's just that they use the mysterious theory of yin and yang change to understand, pay attention to its form, but ignore the essence of the ......"

Cheng Li kept thinking about it while listening to the lecture.

"And then that spirit armor...... If you look at it from the eyes of modern people, it is actually a kind of mecha powered by spiritual power!"

"And their spirit armor refining is not like modern society that uses industrialization, but uses their cultivation method to build it with the way of refining weapons. ”

"Therefore, the spirit armor they have refined is extremely powerful. It can allow the driver to have the ability to challenge beyond the level, and if a Jindan stage monk is driving a matching spirit armor, he can even directly confront the Yuan Infant stage monk!"

"However, I don't know why, although the hardware here is powerful, the software is extremely backward......"

Thinking of the yin-yang arithmetic knowledge he learned today, Cheng Li became a little crazy.

"No, I should say they don't even have a concept of software yet. ”

In the knowledge of the spirit armor that Cheng Li learned in the afternoon, he already knew that there were two ways to control the spirit armor here.

One is physical drive, which is like a person putting on an armor and then directly driving the spirit armor by the body.

However, the height of the spirit armor is often more than ten meters, which makes it very difficult to drive the physical car, even if the cultivators have refined many power rune units, it also makes the physical driven spirit armor only a few body refining cultivators have the ability to drive.

The other is driven by yin-yang arithmetic.

Cheng Li saw the two long strip-shaped buttons on the spirit armor at the beginning, one with Yin written on it, which was all black, and the other with Yang written on it, which was white all over.

These two long strips of buttons are made of yin-yang stone.

There are two kinds of yin-yang stones, yin-yang stones and yang-stones, and their function is to pour the spiritual power that cultivators into them, and only output the spiritual power flow that contains a single yin-yang spiritual son.

Cheng Li now knew that the spiritual power transformed by the cultivator through the spiritual root was a mixed flow of spiritual power between the Yin Lingzi and the Yang Lingzi.

However, if there is a cultivator who injects spiritual power into the Yang Stone, he will get a flow of Yang Spiritual Power that is completely composed of Yang Lingzi, and if he injects spiritual power into the Yin Stone, he will get a flow of Yin Spiritual Power that is completely composed of Yin Lingzi.

Therefore, the so-called yin-yang arithmetic drive is that the cultivator inputs a series of binary language codes to the spirit armor through the yin-yang spirit stone, and then uses this to drive the spirit armor.

Cheng Li knows that this is not impossible.

Through the Yin and Yang Spirit Stone, entering the Yin Lingzi and Yang Lingzi is equivalent to entering 0 and 1.

When the first generation of tube computers on earth was born, computer scientists at that time directly input 0 and 1 into the computer to program and achieve the results they wanted.

Binary languages composed of 0s and 1s, also known as machine languages, are the only computer languages that computers can directly "read".

And in this world of cultivation, in the absence of an operating system written in a high-level language, the yin-yang arithmetic language composed of yin and yang lingzi has also become the only binary language that Lingjia can "read".

"No wonder they keep saying that the spirit armor is too difficult to control, and it is not difficult to control the mecha in binary language?!"
