Two days later.

"Brother Xie Gao!"

Cheng Tian took the Tang knife from Chief Gao.

With a bang, the knife was unsheathed.

Including the handle, the whole knife is about four feet long and weighs about 400 pounds. The entire blade is made of tungsten steel, and the whole body is dark, and even if it is placed in the sun, the blade does not have a trace of reflection.

Cheng Tian waved lightly a few times, although the strength of his arms had exceeded 1,500 catties, it was still not easy to wield.

"You kid, get acquainted with it. I have to hurry up and practice to break through, and when we complete the level of the Heavenly Tower, let's go to the martial arts level task together!"

The mission of the Academy Palace is a task that must be completed on time for students above the martial artist level of the Star Academy. These tasks can be regarded as a test for the cadets, and in fact, they are also an effective way to improve the combat effectiveness of the cadets. After all, it is almost impossible for a martial artist who has not experienced the bloody storm to grow up.

Martial arts level, complete the academy quest at least once a year. The mission of the school palace, in addition to finding opportunities by yourself in the task, you can also get mission pavilion points, which can be used to exchange treasures in the Star Tower, and can also be exchanged for the cultivation time of some treasures.

......

Inside the small courtyard.

Cheng Tian persevered in practicing the exercises.

Most of the time is spent in the painful cultivation of the "Sharpening Mystery Method", this exercise is not difficult for Cheng Tian to get started, but the difficulty is that the cultivation is really painful, making it almost impossible for people to persevere.

After cultivating these days, the progress of his divine consciousness has been rapid, his spiritual power has continued to grow, and his control of his vitality has become more and more proficient, and he is about to reach the cultivation threshold of "Melting God Slash".

"Star Refining Body Technique" also practiced from time to time, and his physique became stronger and stronger.

Only the cultivation of the "Sword Like Silk" knife technique in "Sword World" is always difficult to get started.

......

More than ten days later.

Sweat like a pig.

Turn and slash horizontally, slash violently, and thrust at great speed......

Cheng Tian swung his knife again and again in the small courtyard, and every time he swung the knife, he brought a whining and violent wind, and his momentum was awe-inspiring. If he is seen by ordinary people, I am afraid that he will immediately comment: A master of martial arts, terrifying!

But Cheng Tian still obviously felt wrong!

Very wrong!

According to the exercises, this "knife is like silk" chapter practiced, the knife line is like silk fluttering in the wind, there is no trace of momentum, killing people invisibly, it is not like this at all, a knife is swinged, and the tiger is windy.

It must be that the Yuanqi running line is not right......

For so many days, my "Melting God Slash" has already been introduced, and the first day can basically be effectively performed, but I didn't expect that this yellow-level mid-grade "Sword Like Silk" chapter has been delayed!

Although Utulu had already told himself that martial arts cultivation would never be smooth sailing, Cheng Tian was anxious, after all, the exercises in terms of spiritual power were advancing day by day, and he didn't expect that the cultivation of this sword path would be stuck with him for so long!

Sink your heart!

Change again, practice again......

I don't know how long I've been practicing......

Finally there is a change.

Although the Tang knife is a straight knife, after this knife technique, it makes people feel erratic, and there is no heavy momentum at all. The blade of the knife was chopped, and the knife wind brought up was very small, Cheng Tian tossed and turned in the small courtyard with the knife, and the knife line was quickly cut, which seemed to divide the air into two.

Heh-

Finally!

Cheng Tian finally felt that the knife technique was introduced!

After a few more days of practice, you can go to the Heavenly Tower to set the martial artist level!

......

The first time he came to the back mountain, Cheng Tian looked up at the Ascending Tower. The entire 101 floors stand majestically and towering into the sky.

Cheng Tian, these quasi-martial artists, was just listening to the elders explain the purpose of the Ascending Tower in the martial arts hall, and sure enough, Cheng Tian thought it was an ordinary tower. When I came to the tower today, I realized that this tower covers a very wide area, and the height of each floor is dozens of meters, and it seems that the higher the upper floor, the bigger it is.

How high is the entire tower with more than 100 floors? With Cheng Tianwu's level eyesight, it is impossible to see clearly.

The tower is unmanaged, with only one platform at the bottom, and a small lattice in the shape of a snowflake in the center of the platform. Cheng Tian understood it as soon as he saw it, put his identity token into the grid, and with two clicks, the token was sealed inside, and the door on the first floor of the Ascending Tower automatically opened-

Cheng Tian took a deep breath and stepped into the first floor of the Heavenly Tower.

A real shock!

This......

Although Cheng Tian was willing to believe it, these were all illusions from the spells of high-level martial arts masters!

However, no matter how you look at it, you feel that the entire wall on the first floor is a display screen!

Entering the Tower, the entire floor of the tower is empty, and the walls are divided into 100 areas in turn, each with a portrait and a few large characters.

Cheng Tian didn't have the heart to look at the people and characters on the screen.

I just approached in a daze, and I discerned it in detail.

This is definitely not a spell, although it seems, whether it is the details of the display, the degree of realism or the degree of stereoscopic degree, it far exceeds the imaging technology on the earth, but Cheng Tian clearly feels that this is the display!

"Lord Batuu, what's going on? Isn't this a monitor?"

Baturu was not shocked in the slightest:

"Of course, it's a display technology, and it's much higher than the high-end of the planet. Questions?"

Cheng Tian's worldview collapsed again, obviously it was hard to accept, there is no modern technology in this world, what happened to suddenly give me a hundred monitors?

"Of course there is a problem! Isn't this a martial arts continent with no scientific and technological content?"

"Who told you that this is a martial arts continent with no scientific and technological content? Didn't Elder Wan Jie talk to you about the TV when he first met you?"

"What the hell is going on?"

"Hahaha, you don't think that this continent, which has a population of hundreds of billions, countless strong people, and a history of civilization development in hundreds of millions of years, will have a much weaker ability to develop science and technology than the earth, right?"

Looking at Cheng Tian's stunned appearance, Uturu was almost happy.

"It's hard to ...... Don't...... Isn't it?"

"Cheng Tian, do you think it's possible? Do you really think that everyone is drunk, and you are awake alone?"

"To ordinary people, it may be! They don't have the concept of modern technology at all. But for the powerful, especially the leaders of the entire continent, the so-called modern technology is nothing more than a layer of window paper. ”

"Actually, this is just some common sense in the universe!"

"It doesn't hurt to tell you, after all, that's one of the reasons I sent you here. ”

"I told you before that all civilizations in the universe want to continue forever, but sadly, the vast majority of civilizations and races cannot escape the fate of extinction. ”

"Especially a rudimentary technological civilization that doesn't have a strong leader, say, Earth. ”

Cheng Tian was stunned: "No, I think the earth is still ...... It's safe. ”

Uturu ignored Cheng Tian and continued:

"Even without the influence of external factors, the extinction of low-tech civilizations in the universe is almost doomed. ”

"There are two most common ways for low-level civilizations to extinct themselves, one is that the entire civilization is virtualized and then gradually falls silent, and the other is that with the iterative upgrading of energy, the entire civilization planet is self-destructed. ”

"The first kind of civilization virtualization. Very simply, with the development of scientific and technological civilization and the continuous improvement of virtual technology, it is easy for primary civilization to move towards the end of the virtualization of the entire society in the process of development. Civilization has gradually shifted from the real society to the virtual network, and the consciousness of life has also been uploaded to the virtual world, and it seems that every individual has achieved virtual immortality, and everyone can do whatever they want in the virtual world. However, in reality, it is just some electronic data......"

Cheng Tiandao: "Wait, are you talking about the development of virtual games that simulate the senses 100% in the future, the kind that is more real than the current earth, and people will all live in the virtual world?"

Uturu decisively denied:

"Wrong! Big mistake! It's not 100 percent simulated senses, but a slightly higher level of virtual technology, all of which are directly uploaded to the network by thinking consciousness, and then simulated and stimulated sensory feelings dozens of times, hundreds of times, and thousands of times, completely surpassing the experience of ordinary people in real life. It fully mobilizes every feeling of ordinary people, whether it is happiness, horror, excitement...... It's all far beyond your imagination, any feeling you want can be simulated, and the virtual consciousness can even be immortalized, so that in ten years, a hundred years, and a thousand years, do you think there will still be anyone willing to live in the real world?"

Cheng Tian was silent.

"You probably know that civilization is virtualized and silent, and the iterative upgrade of energy is also easy to understand. The earth has only developed to the initial level of nuclear energy, and has not yet put in place medium and high-end energy means such as sub-energy and material annihilation. Before interstellar migration is realized, a simple energy iteration experiment may be enough to destroy the entire planet, and many primary technological civilizations have hastily drawn an end to the entire race when they first come into contact with the iterative upgrading of middle and high-level energy. ”

"Moreover, there are many forms of energy upgrading. Let's take a simple example of chestnuts, for example, there are two villages fighting. ”

"In the era of cold weapons, there were only occasional casualties in battles, in the era of hot weapons, as long as there was a conflict, the villagers would be ruined at every turn, and in the era of nuclear weapons, any one person pressed a button, and both villages would be destroyed in an instant. You must know that in the entire universe, nuclear energy is not a high-end energy means, and there are many more powerful means behind it. ”

"The most important thing is that in the process of the development of civilization, this kind of people who are willing to press the button have always emerged in an endless stream. ”
