"What...... What? Oh my God, what's going on? Sister Tongtong, why...... How can your Yin Fire melt the Darkiron so easily?"

Seeing this scene in front of him, Lin Feng really couldn't help but exclaim. Since getting the twenty-four Dinghai Divine Beads, Lin Feng's vision has improved by more than one level, and almost only when others treat him almost, there are very few things that can make him exclaim and exclaim.

But the dark iron that Lin Feng couldn't melt no matter how hard he tried before, it was easily melted under Li Yutong's trace of yin fire, which brought Lin Feng the shock and surprise that it brought was really indescribable.

"Lin Feng, I don't know. Just now when I saw this dark iron, I had a feeling as if the yin fire in my dantian could work on it. So I picked it up and tried it, but I didn't expect it to melt the dark iron so easily. ”

After verifying the idea in his heart, Li Yutong also said with a burst of surprise.

"It turns out, Sister Tongtong, although your Yin Fire looks weak, it is an excellent flame for refining weapons, and it is the nemesis of these refining materials. Quick, try this Mithril again, can it melt?"

The excited Lin Feng hurriedly handed over the Mithril dagger again, Li Yutong took a deep breath, and wrapped a trace of yin fire around the Mithril dagger.

Zizizi......

Although it was a little more strenuous than just now, Lin Feng still saw that the Mithril dagger began to melt little by little under the effect of a trace of black yin fire.

"Lin Feng, the Mithril dagger has also melted!"

Seeing that Mithril was also melting under the power of her Yin Fire, Li Yutong was very surprised, she knew that in this way, she would be able to help Lin Feng refine the flying sword.

"Great! Sister Tongtong, it seems that today is really our good luck day, and now we can start refining flying swords!"

Lin Feng was happy for a few seconds, and suddenly a trace of yin fire in Li Yutong's palm was extinguished.

"What's going on?Sister Tongtong, how did your Yin Fire go out?" Lin Feng said strangely.

"I don't know, Lin Feng, it seems...... It seems that the vitality in my dantian has been exhausted. Therefore, there is no way to continue to release the Yin Fire. ”

After looking at his dantian for a while, Li Yutong said apologetically to Lin Feng, "I'm sorry! Lin Feng, my cultivation is still too low." ”

"I don't blame you, Sister Tongtong. You've only been cultivating for less than a week, and you've been able to reach the first level of Qi cultivation and give birth to Yin Fire, which is already very remarkable. However, your vitality is indeed a little lacking, if your vitality is as much as mine, it is possible for us to practice the flying sword today. ”

Lin Feng bit his lip, thought for a while, and then said to Li Yutong, "That's it, Sister Tongtong, you sit down cross-legged and meditate and run the "Innate Kwai Water Technique", I will release the vitality for you to absorb just now, and see if I can replenish the vitality in your body." ”

"Hmm!" Li Yutong followed Lin Feng's instructions and meditated cross-legged to run the exercises.

However, a full fifteen minutes passed like this, and after Li Yutong had been running for a long week, he had finished replenishing the vitality in the dantian.

"It's too slow! It takes a full fifteen minutes to replenish a single Yuan Qi, and these Yuan Qi can only last less than a minute when used to refine Xuan Iron. It seems that this is still a lot of work!"

At this moment, Lin Feng realized why the ancient cultivators wanted to retreat for a few years or more at every turn, and sometimes refining a magic weapon did indeed take decades just to condense and refine the materials.

"What should I do then? Lin Feng, is there a faster way to quickly share the vitality in your body with me?"

Li Yutong, who has been in the business for so many years, is best at being flexible, since this road does not work, he will take another road. So Li Yutong thought about it for a while, and then suggested to Lin Feng, "Lin Feng, can you transmit the vitality to me mouth-to-mouth like last time, and I will directly refine the vitality into the dantian, so that the speed will be much faster." ”

"Mouth-to-mouth transmission of vitality? By the way, why didn't I think of this? Sister Tongtong, the double cultivation in the cultivation of the true often uses this method, so that the vitality of the two of them forms a common cycle, which is a way to quickly replenish the vitality. Of course, the premise is that the two of us must have no distractions and not have the slightest idea of rejecting each other. You have to trust each other with all your heart, otherwise, it is very easy to have a violent vitality and cause the meridians to break. ”

Thinking of this method, Lin Feng is also more cautious, after all, this method is more dangerous, as long as one is not careful, both of them may have their meridians shattered.

"Well, Lin Feng, let's try it!" Li Yutong said with confidence, because it was not a problem for her at all, she already trusted Lin Feng 100%, and the two could also blend together incomparably.

"Sister Tongtong, you have to think about it. When it comes to the transmission of shared energy, neither of us can afford to be distracted. It's better to look at each other ......"

In order to refine the flying sword as soon as possible, Lin Feng also fought hard, and after explaining to Li Yutong, he pursed his mouth, and his thick lips were pasted towards Li Yutong.

"Hmm......"

Feeling Lin Feng's hot thick lips and the warm vitality coming from above, Li Yutong was so comfortable that he wanted to close his eyes, but just now Lin Feng said that he wanted to look at the other party, so he had to open his eyes and look at Lin Feng, and Lin Feng also looked at her while kissing.

Zizi ......

The vitality in Lin Feng's body entered Li Yutong's dantian without any refining, naturally triggering a series of conflicts within the meridians. However, because both of them are practicing the same kind of exercise, and their minds are similar at this time, they have almost entered a state of double cultivation. The violent vitality slowly eased down, and finally successfully merged in Li Yutong's dantian, and then returned to Lin Feng's body from the kiss between the two.

In this way, in the continuous exchange, in less than half an hour, Lin Feng is huge amount of vitality on his body, all of which was exchanged with Li Yutong. It is equivalent to saying that Li Yutong can directly use the vitality transmitted by Lin Feng without causing the slightest rejection.

"Whew...... Sister Tongtong, from now on, I will transmit the vitality behind your back into your body, and you just have to listen to my orders to take those dark iron and Mithril and ...... Ordinary steel can be refined! Tonight, our flying sword will definitely be able to form......"
