Chapter 670： Pass power

Little ÷ Say ◎ Net], ♂ Little ÷ Say ◎ Net],

The ancient cultivators, wanting to refine a magic weapon, often took decades to hundreds of years. The most of the time is spent on refining some ore materials, and the more precious the materials, the more difficult it is to refine.

However, what Lin Feng wants to extract now is not precious ore materials, but only some of the simplest refined iron. Moreover, it is still extracted from steel that has been artificially purified, and the degree of difficulty is hundreds of times easier than that from iron ore.

"Huh...I'm exhausted, it turns out that it takes so much energy to extract refined iron from steel!"

After another hour of persistence, Lin Feng reluctantly refined the steel that weighed half a ton. Except for some black scrap iron residues, Lin Feng finally got a piece of silver-white fine iron, weighed in his hand, and probably weighed no more than a catty.

"Isn't it? Just less than a catty of refined iron, it has taken me two hours, and almost the whole body's vitality to refine? This refining tool is really hard work!"

Feeling that the dantian vitality in his body was already lacking, Lin Feng received the vitality real fire, and decided to stop here today, and he was unable to refine it anymore. After two hours of hard work, less than half a catty of refined iron was obtained, and Lin Feng really realized the difficulty of refining.

"Only half a ton of steel can produce a catty of refined iron, based on those inherited experience. Even if it is to refine the lowest-grade magic weapon flying sword, at least ten catties of refined iron are needed. It seems, The ten tons of steel outside may not be enough!"

Knowing that refining steel to make flying swords is not something that can be done in one breath, Lin Feng is not so anxious. He meditates cross-legged to regain the vitality he has just consumed, and put the piece of silver-white fine iron that is less than a catty into the Shenshui space. After that, he got up and walked out of the alchemy room.

"Lin Feng, are you out? How are you? Has the Feijian refining succeeded?"

Seeing Lin Feng coming out of the alchemy room, Li Yutong stepped forward and asked with concern. That towering breast, beautiful face, and incomparable figure is a perfect goddess.

"No, it’s much harder than I thought. I’m afraid it’s a long-term war of resistance. It took me more than two hours to refine half a ton of steel, and the refined iron was not even a catty. To."

Lin Feng smiled bitterly and said, "Sister Tongtong, I am afraid I will consume these steel materials in the next week. Insurance estimates that within half a month, the prototype of the flying sword can be refined."

"Everything is difficult at the beginning! Lin Feng, haven't you said that? You may be the last cultivator on this earth. That is the cultivation method of immortality, countless miraculous spells and medicines. People find it incredible. You are only making Feijian for the first time. Don't be impatient. Although I don't know what the practice is, I know that no matter what I do, I can't eat hot tofu in a hurry..."

Li Yutong walked over with a smile, and pasted Lin Feng's side to comfort Lin Fengdao with concern. The feminine scent emanating from her is a very refreshing fragrance, very pure and clean, and after smelling it, it seems to be in a paradise world with no troubles.

"Thank you! Sister Tongtong, I believe that you have been by my side to help me encourage me, this flying sword will definitely be able to refine successfully. Moreover, Sister Tongtong, in fact, you are a pure Yin body, you can also practice My "Xiantian Kui Shui Jue". However, the effect is a bit worse, or I will teach it to you now?"

After digesting many inheritance memories in the past few days, Lin Feng discovered that the pure Yin body although the most suitable cultivation technique is pure Yin attribute. But the "Xiantian Kui Shui Jue" practiced by Lin Feng also belongs to the Yin attribute, and Li Yutong's pure Yin body can be practiced.

"Really? Lin Feng, that means, I can become a cultivator like you now?" Li Yutong said in surprise.

"En! Sister Tongtong, although my technique is not the most suitable for you, it shouldn't be much worse. Moreover, mainly because your pure Yin body is very suitable for cultivation, I am afraid that the speed of cultivation is faster than mine. It's a physique against the sky..."

Lin Feng nodded, and then said embarrassingly, "However, I don't have the Pill of Pei Yuan right now. If you want to teach the "Xiantian Kui Shui Jue" to you, you must get a breath of vitality into your body. , And then lead you to run "Xiantian Kui Shui Jue" for a big week."

"Take a breath of vitality? What do I need to do? Lin Feng, I will cooperate with you. Moreover, if I also become a cultivator, can I help you refine alchemy and refining tools together in the future?" Li Yutong trusts Lin Feng 100%. , I believe he will not harm herself, so she will do whatever Lin Feng says.

However, Lin Feng said with a hint of embarrassment: "Sister Tongtong, as long as you have cultivated vitality and real fire, you can naturally refine alchemy and refining tools. I will also teach you these things, but... Mouth vitality, need to... mouth to mouth, is it okay?"

Although Lin Feng has kissed Li Yutong more than once, after all, there is still a difference between men and women. What's more, Li Yutong is such a beautiful woman who looks like a fairy, and Lin Feng thought of kissing Li Yutong, little heart Just puff and jump straight.

On the contrary, Li Yutong heard this polite inquiry from Lin Feng and couldn't help but laugh, and said, "Lin Feng! Didn't we never kiss? You and sister Is it serious? And..."

As he said, Li Yutong also had a face like a peach blossom, lowered her head shyly, her teeth bit her cherry lips, and said, "Furthermore, Lin Feng, I'm afraid my sister will only be touched by you in this life. If you don't kiss me , Isn't that sister going to be alone forever?"

When the coquettish Li Yutong said this, he was really full of amorous feelings and charming attitudes, and the meaning that had been promised by his body made Lin Feng both moved and excited, and could not help but grab Li Yutong’s little boy. Man waist pulled over and kissed affectionately without saying a word.

"Hmm..."

Feeling Lin Feng's familiar thick lips and dishonest tongue, Li Yutong also closed his eyes with emotion, immersed in this affectionate kiss, let go of all the precautions in his heart, and completely handed himself over to Lin Feng.

""Xiantian Kui Shui Jue", big Zhou Tian revolves, pass the power!"

Sucking on Li Yutong's small and gentle lips, Lin Feng enjoyed it very much, but he did not forget the business, mobilized the vitality in his dantian, and began to teach Li Yutong.
