Only then did Xu Yi see that it was a sword, no more than two feet long, covered with stars, and the whole body was bright and clean, and he knew that it was not ordinary.

Elder Song looked at the sword body and sighed, "It's a pity, it's a pity, if it's not careless, it should be able to reach the middle grade, hey......"

Xu Yi didn't see it, sat cross-legged on the side, trying his best to calm the boiling qi and blood, and recovering his physical strength that was almost to the limit.

Elder Song didn't urge him, he sat and played with the Xingyue Sword by himself, muttering something in his mouth.

After half a pillar of incense, Xu Yi stood up, walked in front of Elder Song, took out the dragon crocodile skin and handed it over, and said with a smile, "Thank you Elder Song, I hope that within five days, I can become an armor!"

"The old man only said that he would help you forge your armor, but he never promised that it would be completed in a few days, five days is too short, and it will take a year and a half to say the least!" Elder Song twisted his beard lightly and shook his head slightly.

Xu Yi was extremely angry, he didn't expect the old man to dare to play with words, and he was blind to the dignity of the grandmaster of the Qi Sea Realm.

Just as Xu Yi was glaring at him, Elder Song laughed and said proudly, "How about it, boy, fight with the old man, you are still tender." That's it, I won't tease you, what kind of person the old man is, what he says, it will be loud when it hits the ground, how can he see it like a junior like you. It is not difficult to become a nail in five days, but whether it is good or bad depends on the mood of the old man. ”

"You kid ruined the old man's mood today, and just helped the old man pull the box, which is considered to be part of the compensation, but the old man is depressed, and most of it has not been eliminated, I think so, you help the old man pull the box three more times to eliminate the old man's depression, and the old man will do his best to forge armor for you!"

After talking for a while, Elder Song's focus was still on Xu Yi's coolie.

The quality of the Xingyue Sword forged did not meet Elder Song's psychological expectations, but after all, there was a previous situation that almost exploded before.

In fact, the moment he rushed into the refining room and saw the corpses of the two wrestlers, Elder Song didn't have much hope for this exercise.

After Xu Yi took over the wind box, the stable supply of fire made the situation improve, and finally he was able to forge such a Xingyue Sword, although the quality was not excellent, but it was not broken, which made Elder Song extremely satisfied.

With this satisfaction, he fell in love with Xu Yi, and introduced it into the middle by exercising the dragon crocodile skin.

"Since Elder Song can afford to be below, how can he not know how to lift up below. ”

Xu Yi actually responded.

Elder Song was dumbfounded, he couldn't believe his ears, but in an instant, he had already seen Xu Yi's cunning, and he didn't even bother with this kid, so he obediently entered the court, which caught him off guard.

Xu Yi's heart flashed, and he knew the old man's thoughts, and after a moment of conversation, he said, "But before I promise Elder Song, I ask Elder Song to ask a question and a condition, and ask Elder Song to agree." ”

In fact, the reason why he responded casually was because he felt the push and pull wind box, which was faintly beneficial to his body.

Since reaching the peak of body forging, Xu Yi threw away the heavy iron, but he has never found a new method of forging the body, because the ordinary body forging equipment, the method, is not much use for him, that day by chance to invent the lifting stone lock, but also a means to fatigue the body.

And this time, pushing and pulling the wind box at a constant speed, he actually felt a mysterious feeling of power penetrating deep into his blood and soaking into his bone marrow.

If there is a benefit, how can he not agree.

But he said that Xu Yi made such a request, and Elder Song's heart relaxed, and said with a smile, "Say it, as long as it's not too much, the old man will promise you!"

Xu Yidao, "My question is still premised first, I don't know what a spatial attribute is, why does dragon crocodile skin have such an attribute? In addition, in addition to spatial attributes, are there any other attributes?"

Elder Song seemed to expect him to ask this question, so he twisted his beard proudly and said with a smile, "That's it, the old man will send you a mask this time." Do you know what is the root cause of everything in the world? In other words, what is the composition of all things? ”

"Atom!" Xu Yi blurted out, raising land, and his face turned red.

Elder Song was stunned by what he said, "What is an atom, why has the old man never heard of it." ”

"Atoms, uh, are small, tiny, all things, aren't they all small and big, atoms are things that can't be smaller. ”

Barely reunited, Xu Yi quietly wiped his sweat.

I don't know who did this, it's ridiculous, how can we generalize everything in the world. I'll enlighten you, the things of the world, the extreme, can not get rid of the five elements of gold, wood, water, fire and earth, these five substances, constitute all things in heaven and earth, therefore, all things may have golden attributes, such as the knife can cut wood, this is called rigidity and softness, or there are wood attributes, such as trees can enter the soil, this is the best of the best; the rest of the surplus, too many to mention. ”

"In short, all things are gathered by these five substances, and if something gathers more gold, it is more metallic, such as this star-moon sword, which may not have fire and earth, but the gold is the heaviest, so it is displayed in front of people, all of them are metallic, and they can be forged. And things gather from these five elements, so there are these five elements. In addition, there is a great miracle between heaven and earth, wind, thunder and lightning, etc., which also affect all things, and its quality is hidden, and the things are opposite, such as the wind stone, the sky thunder wood, and it is inevitable to create and be born. ”

"Therefore, there are special attributes such as wind and thunder. Of course, if you exhaust the truth, the wind and thunder do not give birth to the five elements. It's just that people pass it on by word of mouth for the sake of easy memory, so they use wind and thunder as their attributes. ”

In addition to the five elements, there are two fundamental laws of time and space, so there are two kinds of time attributes and space attributes. For example, the longevity fruit and other exotic fruits that can prolong life can be regarded as containing the attribute of time. And this dragon crocodile skin, when it is small, can cover the house, and when it is large, it can cover the house, and it can be large and small, doesn't it contain spatial attributes?"

Xu Yi didn't expect that when he asked, he would lead to the generation of all things, the truth of heaven and earth, like an enlightenment, suddenly opened, and he was grateful to the old man in his heart, but he said, "At the beginning, I took out the dragon crocodile skin, and you said that it also has a space attribute, which means that the dragon crocodile skin with the space attribute is rare." Could it be that there is still a dragon crocodile skin that does not have spatial attributes?"

He was looking for reason, and he didn't want to have the slightest doubt in his heart.

Elder Song said, "Dragon crocodile skin is not easy to obtain, many people in the world do not know its treasure, but there are very few masters who can forge space attribute leather, therefore, dragon crocodile skin is in the world, and the world has multiple defense capabilities." And the value of the size of the leather can not compete with the size of the house. Therefore, the person who obtains the skin invites more skilled craftsmen to expand and shape it, cut it and sell it, where can the dragon crocodile skin still expand and contract freely after cutting, and naturally there is no longer any space attribute. ”

"Elder Xie's teachings!"

Xu Yi respectfully bowed to Elder Song.

Xu Yi has always respected the benefactor who preaches and solves doubts, from Lichen, to Master Zhou, to Elder Song.
