A faint black flame just came out of Li Yutong's palm, and it was with a cold aura, which didn't look like a flame at all.

"Yuan Qi True Fire? How can it be like this? Sister Tongtong, you are only practicing Qi at the first level! How can you spur out the Yuan Qi True Fire? Moreover, my Yuan Qi True Fire is all cyan, why is yours black! Moreover, I can't even feel the temperature of your Yuan Qi True Fire, but there is a faint coldness. What the hell is going on?"

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

"Lin Feng, I don't know. Since yesterday, after the vitality in my body began to accumulate into the dantian, I felt the breath in my body gushing into the dantian one after another. Later, such a black flame was formed in the dantian, and I also saw you use the Yuan Qi True Fire Refining Weapon and alchemy, so I tried to draw this black flame into my palm. I didn't expect it to really come out......"

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

"It's amazing! Sister Tongtong, I think it may have something to do with your special physique. Your physique is a pure yin body, so there is already a strong yin power in your body. Therefore, you have only just practiced the first level of qi, and the power of yin qi is instilled into the dantian, forming this black flame. Your black flame should be Yin Fire! There is not the slightest breath of flame, but it is full of Yin Cold, and it is most suitable to be called Yin Fire. ”

Combined with Li Yutong's special physique, Lin Feng came up with such an explanation. However, this is also a good thing for them. After all, the faster Li Yutong's cultivation speed, the more places he could help Lin Feng in the future. It is very likely that there will only be two of them cultivators left on the entire earth.

"Okay, Sister Tongtong, you don't have to worry about that yin fire for now. Anyway, the ability derived from the Yin Qi in your own body will not do you any harm. Hey, hey, I'll show you something good, ...... first."

Putting aside Li Yutong's yin fire problem first, Lin Feng took out the three darts made of dark iron and a Mithril dagger from the Shenshui space.

Ding Ding ......

Lin Feng touched the dagger and the dart, and made a very crisp sound. Li Yutong's eyes were also very poisonous, and as soon as he saw these three darts and the dagger, his eyes lit up: "Lin Feng, where did you get this good thing? This dart is light and thin, and the texture is very hard and sharp. Obviously very extraordinary, and this dagger is even more remarkable, how can I feel a force from the dagger that absorbs the vitality in my body?"

"Sister Tongtong, I'm quite knowledgeable. The three darts were made of Darkiron, and the dagger was even more impressive, all made of Mithril. Lin Feng said with a smile.

"What are Xuantie and Mithril?" Li Yutong didn't have Lin Feng's cultivation inheritance memory, so he didn't have any concept of Xuantie and Mithril.

"Let me give you an analogy! Look at the steel over there, I have worked so hard to extract only a little bit of fine iron from it. This refined iron is only a material that meets the lowest grade of refining flying swords. This dark iron is the most suitable material for refining flying swords, and it is not known how many times higher than refined iron. And Mithril is not to mention, you also felt it just now, the absorption of vitality and aura is almost 100%, as long as such a small piece of Mithril is added to the refining flying sword, the nature of the flying sword can be multiplied!"

Lin Feng made a simple analogy, and Li Yutong immediately understood the preciousness of these Xuaniron and Mithril, and said in surprise: "Lin Feng, doesn't that mean that you don't have to work hard to refine refined iron now, as long as you use these Xuaniron and Mithril, you can immediately refine the flying sword?"

"Forehead ......"

Hearing this, Lin Feng could only smile bitterly and said, "Theoretically, it can be like this, but I am only now practicing the third layer of qi, and my vitality is really hot, I'm afraid it will be difficult to refine such a hard Xuaniron and Mithril." ”

This is also Lin Feng's biggest headache, the density and hardness of the dark iron, I don't know how many times harder than the refined iron, Lin Feng is so difficult to refine even ordinary steel, to refine the dark iron and Mithril, I am afraid that it will have to wait until the true fire of the vitality in the foundation building period to be able to have such power.

"Ahh

"Yes, it's equivalent to guarding the treasure mountain, but I still have to try it, what if my Yuan Qi True Fire can melt this dark iron?"

Picking up a Xuantie dart, Lin Feng held his breath and condensed, summoning his cyan Yuan Qi True Fire from the dantian, and then blazing on this Xuantie dart.

Today's Lin Feng, the vitality in the dantian is already relatively abundant, and after meditating and cultivating every night, it is becoming more and more condensed. Therefore, the power of the Yuan Qi True Fire has also risen, from the previous trace of flame to now it is already a beam of cyan true fire, and the temperature of the core flame is estimated to be able to reach tens of thousands of degrees.

Zizizi......

The True Fire of Yuan Qi burned on top of the Darkiron, causing the Darkiron to make a sizzling sound, but it seemed that it was still very early before it was about to melt.

"Sure enough, Sister Tongtong, you see that my vitality true fire is powerful enough now. But when it was burned on top of this dark 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 dark iron could not be melted as expected, and he unwillingly picked up the Mithril and burned it with the cyan Yuan Qi True Fire again.

But this Mithril seemed to be of a higher level than that dark iron, Lin Feng didn't even hear a sizzling sound, the Mithril dagger was immobile in the cyan flame, and even used this flame to absorb the vitality in Lin Feng's body.

"No, the Mithril dagger can't burn, hey, Sister Tongtong, it seems that in the short term, I still have to honestly condense the fine iron. However, fortunately, now that the power of my Yuan Qi True Fire has increased again, it is estimated that in another three or five days, I will be able to condense all the remaining steel into fine iron. ”

Lin Feng sighed, and was about to go to the side to move the steel over for refining, but Li Yutong curiously picked up a dark iron dart, and a trace of black yin fire rose in the palm of his hand, and said to Lin Feng: "Lin Feng, do you want to try it with my yin fire?"

"Sister Tongtong, you only have a trace of yin fire, and you are even weaker, so you must not ......"

Lin Feng, who didn't take it seriously, hadn't finished speaking, and his eyes were about to spit out, because he saw that in Li Yutong's palm, the weak yin fire in his mouth actually melted the dark iron in one fell swoop.
