Only then did Xu Yi see clearly that it was a sword, which was only two feet long, covered with stars, and was bright all over the body. You could see that it was not an ordinary person when you saw it.

Xu Yi disappeared without hearing, sat cross-legged, trying his best to calm down the boiling qi and blood, and restore his physical strength that was almost at its limit.

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

Xu Yi was extremely angry, but he didn't expect that the old man would dare to play the word game, which would waste his dignity of the master in the Qihai Realm.

"You kid ruined my mood today and helped me pull the box just now, which was considered a part of it. However, I have a lot of depression in my heart, and most of it has not yet disappeared. I think this is the case. If you help me pull the box three times to relieve my depression, I can do my best to forge your armor for you!"

The quality of the Star Moon Sword forged did not meet Elder Song's psychological expectations, but after all, there was a previous situation where he almost exploded the furnace.

It was still Xu Yi who took over the wind box and gave the situation a stable supply of fire, which improved the situation. He was able to finally forge such a star-moon sword. Although his appearance was not consistent, he was not incomplete, which made Elder Song extremely satisfied.

"Since Elder Song respects me, how can I not be polite?"

Elder Song was stunned and could not believe his ears. After only a moment of getting along, he had already seen Xu Yi's cunning. He didn't even stubbornly with this boy, so he got into obediently, which caught him off guard.

In fact, the reason why he responded casually just now was that he felt that pushing and pulling the wind box was of great benefit to his bodybuilding.

This time, he pushed and pulled the wind box at a constant speed, and he felt a mysterious feeling of power penetrated into his blood vessels and soaking his bone marrow.

But when Xu Yi made such a request, Elder Song felt relieved and smiled, "You can say it, as long as it's not too much, I promise you!"

Elder Song seemed to have expected him to ask this question, and smuggled his beard with pride and said, "Forget it, I'm going to send you a fool this time. Do you know the root of all things in the world? In other words, it's also what all things are composed of."

Elder Song was stunned by him, "What is atom? Why have I never heard of it?"

After barely reuniting, Xu Yi quietly wiped his sweat.

"In short, all things are formed by these five substances. If a certain object gathers more gold, then the metallic nature is heavy. For example, this star and moon sword may not have no fire and earth, but the metallic nature is the most important, so it is displayed in front of people. They are all metallic nature, so they can forge things. Things gather from these five elements, so they have these five elements. Gold, wood, water, fire and earth, and all things do not escape these five attributes. In addition, there are great gods, wind, thunder, lightning, etc. in the world, which also influence all things. Their substances are hidden in them and produce opposite sex, such as wind, stones, sky and thunder, and all are born from nature."

"In addition to the five elements, there are two principles of time and space. Therefore, there are many time attributes and two space attributes. For example, the fruit of the longevity that can prolong life can be regarded as containing time attributes. And this dragon crocodile skin is only a square inch, and when it is large, it can cover the house, and when it is big, it can contain both space attributes. Isn't it?"

What he asked for was the truth and he didn't want to have any doubts.

"Thank you for your teachings!"
