Martial arts cultivates oneself, practices qi and blood, trains muscles and bones, and exercises viscera, which can be regarded as a typical foreign kung fu. Although it is an outer way, if it is practiced well, it is strong and powerful, even if it is attacked by the Zhuji Immortals with immortal arts, it will not die easily.

Therefore, this first realm is the realm of qi and blood, and after achieving the realm of qi and blood, he can be regarded as an acquired martial artist in the true sense.

Martial artists of this level usually have a simpler way of classification - they can withstand a blow from a Qi cultivator without dying (not considering the immortal bonus), so they have a nickname, called a palm realm.

The acquired martial artist who has just started has the power of a bull, full of strength, and a solid physique. On this basis, continue to polish, and the strength can continue to grow before achieving the second realm, as for the effect, it depends on what kind of martial arts are being cultivated.

If it is a martial art like the Bull Demon Fist, the strength will continue to increase, cultivate to a high depth, blast out with a punch, push the eight horses sideways, and pull the nine cows back is still no problem. In the case of not reaching the second realm, it is said that the highest can withstand the power of the nine palms of the Qi cultivator.

Xia Xiaochi practiced the shadow finger, and he didn't expect to push the eight horses horizontally, but with one finger poked out, it was okay for a horse to bleed to death. But the endurance is average, and now it is a palm realm.

At the age of sixteen, it is not too early to reach the acquired realm, and the real genius is already innate at this time. However, in East Lake College, there are not many people who have reached this step.

If you talk about Xiaoai, Li Xize, Cao Wei, Cheng Jiadong and a group of teenagers have all reached the level of the pride of heaven in East Lake College, so understand, Xia Xiao's late arrival is also counted in the ranks of the pride of East Lake College, I don't know how to win or lose if you talk about Xiao Ai.

He has confidence in his heart, and it is not so empty to talk about Xiaoai again, and there is even a sense of eagerness to try it in his eyes.

However, after the last time, Tan Xiaoai didn't ask him for a fateful sticker again, which made him so disappointed.

Today's class is as usual, and it is Xia Xiaochi's favorite strange things.

The old professor drank two taels of wine before class, and his interest was relatively high, so he talked endlessly, and even had a bit of storytelling.

“...... The lotus stone is a thing that absorbs all the light that comes in, so it always looks pitch black. It's easy to create the illusion that it's a black stone. But black still refracts light, and lotus stone does not. If a beam of light hits the lotus stone, it will never escape. If the beam is thick enough, you can even see that part of the light passes around the lotus stone, leaving a black hole in the middle. This is the characteristic of lotus stone, also called relative property. Note that the following is a knowledge point to be tested...... It is the distinction between relative and absolute characteristics. Xia Xiaochi, you can answer. ”

Xia Xiaochi stood up: "The so-called relative characteristics mean that if there is a contradiction in the characteristics, then it depends on the strength of the characteristics of both sides. For example, the indestructible spear and the unbreakable shield, when the two meet, it depends on the strength of the characteristics of both sides, and ends with one overpowering the other. The characteristic that can be restrained by the hostile characteristic is the relative characteristic. And the absolute nature is that it will not be broken no matter what. ”

"Very good, sit down. The old professor continued: "Then how do you distinguish between relative and absolute properties? In fact, there is a very simple way, and that is to look at the number of strange things. Although knowledge has been modifying, increasing, and changing with our cognition, there are some things that have been determined until now, and there have been no counterexamples. What determines absolute and relative properties is actually the same, which is the scarcity of matter itself. For example, lotus light stone is a relative property. Why? Because there's not just one piece of lotus stone. Because there is not only one piece, the characteristics of lotus light stone are not absolute. If there is a type of light that is absolutely unabsorbable on the Lotus Stone, and the degree of characteristics is higher than that of the Lotus Stone, then the Lotus Stone cannot absorb it. And if there is a strange thing in the world, only this one, note that it is the only one of absolute nature, and has nothing to do with whether it is found or not, then the characteristics of this strange thing are absolute characteristics. ”

The old professor took a sip of tea and continued: "Three hundred years ago, our human race discovered a strange thing in the deep cold winter, it was an eternal burning flame, there was no substance in the flame, but it just wouldn't be extinguished. Our clan has used countless methods to finally confirm that this is a flame that will never be extinguished, so it is called the Flame of Immortality. So far, this unquenchable flame is the only one that has been discovered, so it is tentatively confirmed to have absolute properties and cannot be extinguished under any circumstances. Of course, if we find a second unquenchable flame, it means that it is no longer absolute. But through other means, our clan has confirmed that there will be no second unquenchable flame in the world. ”

Xia Xiaochi raised his hand: "What happens if you add a combustible substance to the Immortal Flame?"

The old professor replied, "The characteristic of the unquenchable flame is that it is never extinguished, not that everything is burned. So at that time, it was moved with just a piece of iron. Later research found that although the Flame of Immortality does not burn everything, it does release energy during the combustion process, even if no matter is put into it, and no matter how much matter is invested, it releases the same amount of energy. Based on the characteristics of this unquenchable flame, our human race later invented the first and only perpetual motion machine. Unfortunately, the Flame of Immortality was too small and could provide little energy, so it ended up being placed on our ultimate warship, the Victory, and became the core drive of the Victory. ”

Xia Xiaochi heard it: "Then how did these strange things appear?"

"It's a mystery for the ages. Until now, we have not been able to give a satisfactory explanation for the appearance of strange objects. Now the most common saying is that the power of heaven and earth is naturally conceived. ”

"What happens if the Absolute Spear and the Shield collide?"

The old professor said: "This has not happened until now. For a long time, we have not found a strange thing with the absolute nature of opposites. Therefore, the study believes that it is likely that when heaven and earth give birth to strange things, this situation is automatically avoided. And if there really is, then there are only two possibilities. Either it works at the same time, or it doesn't work at the same time. ”

Xia Xiaochi said again: "Then since it is naturally conceived by the power of heaven and earth, is it possible that heaven and earth will give birth to an immortal flame in the future?

"It's possible. Professor Tan replied: "But it has not been confirmed so far, maybe there will be a chance in the future, you can go and look around!"

"I will!" Xia Xiaochi nodded seriously: "My dream is to travel all over the famous mountains and rivers, travel the world, see all the strange things in the world, and even, get out of this world and travel the universe." ”

The class burst into laughter.

Obviously, this dream is a bit big and unrealistic.

The old professor also smiled: "It's a good thing to have a dream, work hard." ”

Xia Xiaochi actually wanted to know if the stone that the Love-Destroying Demon Venerable used to refine the Emotion Destroying Ring would be some kind of strange thing. And considering that he didn't know the knowledge of the Demon Venerable of Extermination, it might be some kind of strange thing with absolute characteristics, at least it was also a strange thing with extremely high relative characteristics. If this is the case, it means that the power of one's happiness is likely to be repaired no matter what kind of damage.

It's a pity that I can't ask these words, I can only keep lingering in my heart.

Just thinking about it, a shout suddenly came from outside: "Xia Xiaochi, your sister is fighting with someone!"

What?

Xia Xiaochi rushed out.
