Chapter 788

A faint black flame came out from the palm of Li Yutong's hand, with a cold breath, which didn't look like a flame at all.

"Vitality is really fire? How could it be like this? Sister Tongtong, you're only practicing Qi now! How can we summon up vitality? Is it true fire? Moreover, my vitality is really blue. How can yours be black! Moreover, I can't feel the temperature of your vitality and true fire, but there is a faint cold. What the hell is going on? "

Seeing this trace of black vitality in Li Yutong's palm, Lin Feng carefully observed it and asked.

"Lin Feng, I don't know. Since yesterday, the vitality in my body began to accumulate in the Dantian. After that, I felt that the breath of my body poured into the Dantian. Later, such a black flame was formed in the Dantian. I also saw you refining elixir and elixir with vitality real fire, so I tried to lead this black flame to my palm. I didn't expect it to come out... "

Li Yutong controlled the black fire, danced in the palm of his hand, and then took it back.

"How amazing! Sister Tongtong, I think it may be related to your special constitution. Your constitution is a pure Yin body, so there is a strong Yin Qi force in your body. Therefore, when you just practiced Qi, Yin Qi power was instilled into the Dantian, forming this black flame. Your black flame should be Yin Fire! There is no breath of flame, but it is full of Yin cold. It is most suitable to be called Yin fire. "

Combined with Li Yutong's special constitution, Lin Feng came to this explanation. However, this is a good thing for them. After all, the faster Li Yutong cultivates, the more places he can help Lin Feng in the future. Most likely, there are only two practitioners left on the whole earth.

"All right! Sister Tongtong, you don't have to worry about the Yin Fire first. Anyway, it's the ability derived from Yin Qi in your own body, and it won't hurt you. hey! Let me show you something good... "

First put Li Yutong's Yin Fire problem aside. Lin Feng took out three black iron darts and a secret silver dagger handed over from the concert from Shenshui space.

Ding Ding

Lin Feng touched the dagger and dart and made a very clear sound. Li Yutong's eyes were also poisonous. As soon as he saw the three darts and the dagger, his eyes lit up: "Lin Feng, where did you get this good thing? The dart is light and thin, and its texture is very hard and sharp. Obviously, it's extraordinary, and this dagger is even more wonderful. How can I feel a force absorbing the vitality of my body coming from the dagger? "

"Sister Tong Tong, you know the goods very well. These three darts are made of black iron, and the dagger is even better. They are all made of secret silver. " Lin Feng said with a smile.

"Xuantie? Mithril? What are they? " Li Yutong has no memory of Lin Feng's cultivation and inheritance, so he has no concept of xuantie and Mithril.

"Let me make an analogy! Look at those steels over there. I worked so hard to refine them that I could only extract a little refined iron from them. This refined iron is only the lowest grade material for refining flying sword. This black iron is the most suitable material for refining flying sword. Compared with refined iron, I don't know how many times it is high-grade. Not to mention the secret silver, you just felt that the absorption of vitality and aura is almost 100%. As long as you add such a small piece of secret silver into the refined flying sword, you can double the nature of the flying sword! "

Lin Feng made a simple analogy, and Li Yutong immediately understood the value of these black iron and secret silver. He was surprised and said, "Lin Feng, don't you mean that you don't have to work hard to refine refined iron now? As long as you use these black iron and secret silver, you can refine flying swords immediately?"

"Well..."

Hearing this, Lin Feng could only smile bitterly and say, "theoretically, it can be so, but I only practice three layers of Qi now. My vitality is really fire. I'm afraid it's difficult to refine such hard black iron and secret silver."

This is also Lin Feng's biggest headache. The density and hardness of black iron are many times harder than refined iron. Lin Feng is so difficult to refine ordinary steel. To refine black iron and secret silver, I'm afraid he can't have such power until he reaches the vitality of the foundation period.

"Ah? Doesn't that mean that we have such good refining materials, but we can't use them at all? " Li Yutong also said disappointed.

"Yes! It's equivalent to guarding Baoshan in the air. However, I still have to try. What if my vitality can melt this black iron? "

Picked up a black iron dart, Lin Feng held his breath and summoned his blue true fire from the Dantian, and then burned on the black iron dart.

Today, Lin Feng, the vitality in the Dantian has been relatively abundant. After meditating and practicing every night, he is becoming more and more solid. Therefore, the power of vitality real fire has also increased. From the previous trace of flame to now it is a cyan real fire, and the temperature of the core flame is estimated to reach tens of thousands of degrees.

Zizizi

The true fire of vitality burned on the black iron, making the black iron make a sound of Zizi, but it seems that it is still early to be melted.

"Sure enough, sister Tong Tong, you see, my vitality is really fire. Now it's powerful enough. But burning on this black iron, there was no movement at all, and it was impossible to melt it even a little. "

With a sigh, Lin Feng saw that the black iron could not be melted as expected, and reluctantly picked up the secret silver and burned it again with a cyan real fire.

But the secret silver seemed to be higher than the black iron. Lin Feng didn't even hear a sound of Zizi. The secret silver dagger didn't move like a mountain in the blue flame, and even absorbed the vitality of Lin Feng's body through the flame.

"No! The Mithril dagger can't burn, alas! Sister Tongtong, it seems that in the short term, I still have to refine refined iron honestly. However, fortunately, now my vitality and true fire power have increased again. It is estimated that I can condense all the remaining steel into refined iron in three or five days. "

Lin Feng sighed. When he was going to move the steel to refine, Li Yutong curiously picked up a black iron dart, and a black Yin fire rose in the palm of his hand. He said to Lin Feng, "Lin Feng, you don't need my Yin Fire to try?"

"Sister Tongtong, your Yin fire is only a trace, weaker, absolutely not..."

Before Lin Feng finished his words, his eyes were about to spit out, because he saw that the weak Yin Fire in his mouth melted the black iron in the palm of Li Yutong's hand.
