As Lin Feng's vitality was continuously transmitted to Li Yutong, the trace of Yin Fire in her palm began to grow slowly, and then quickly integrated a whole black iron dart into a group.

"Lin Feng, it's melting! Melted... The whole black iron has melted. Are we going to use black iron to refine flying swords now? "

At this time, Li Yutong and Lin Feng were united. When they saw the melted black iron, they were pleasantly surprised and cried inexplicably.

"Yes! Although it's a waste to refine flying swords with so many black iron, I'll recast this flying sword when I can improve my cultivation and refine a higher-level flying sword in the future. "

Controlling the melting black iron, Lin Feng immediately rubbed in the refined iron he refined every day a few days ago. In this way, there is a silver metal liquid in the air, which is the state after the fusion of black iron and refined iron. It is called the sword embryo when refining flying sword.

"Sister Tongtong, I can't burn the black iron. Therefore, you need your Yin Fire help not only in the process of melting black iron. Now start refining the flying sword. You also need your Yin Fire to help. "

Lin Feng's spiritual consciousness controlled the silver sword embryo, and then began to play various Dharma formulas and arrays with vitality. These are inherited by Lin Feng from the memory of Xiuzhen inheritance.

High wind array!

Thick earth array!

Thunderbolt array!

Xuanqing array!

Immortal killing array!

……

One array after another and runes were penetrated into the sword embryo by Lin Feng with spiritual knowledge, and then the whole sword embryo flashed a halo layer by layer. Obviously, these arrays have taken root and worked in the sword embryo.

"Speed! Attack! These are the two most important attributes of flying sword... Now I have entered many different arrays in it, which just conforms to the mutual generation and mutual restraint of the five elements. In this way, although my flying sword is not the fastest or the most powerful, it is the one with the most balanced attributes. "

Lin Feng could have completely put all the arrays inside into the attack type array or speed type array, but considering that this is his first flying sword, it's better to have more functions for some emergencies.

Because after all, this is the earth with only martial artists. Lin Feng doesn't need so strong attack power. The general spirit weapon flying sword is enough to double Lin Feng's combat power. Even if he meets a martial artist with great perfection the day after tomorrow, he won't be afraid at all. As for speed, Lin Feng didn't use a flying sword, so he still played several speed arrays inside.

"All right! Sister Tong Tong, I have entered three hundred and seventy-one arrays into our flying sword, including five offensive arrays, five speed arrays and three defense arrays. The rest are arrays with various auxiliary functions. Now, we can completely shape the sword embryo. "

Lin Feng was also the first time to refine the flying sword, which was completely refined according to the method of inheritance and memory. Because of his limited ability, he can only refine spirit level flying swords, so he can't depict too many arrays in flying swords, generally no more than 30. Lin Feng is a little conservative and only depicts 21 arrays.

After all, the more arrays depicted in the flying sword, the more power and functions the flying sword will use, but the more Aura it will consume to drive the flying sword.

Considering that he is only a three-tier cultivator of Qi, even if he can refine a higher-level and more powerful spirit weapon flying sword, he can't drive it. Therefore, Lin Feng chose this scheme for rational consideration.

"Sister Tong Tong, do you like the style of flying sword? Now the array of the core part of the flying sword embryo has been described. After the sword embryo is shaped, the flying sword will be refined. "

Low level spirit tools only involve simple array depiction, so it's not troublesome to practice Qi. If it is a higher-grade Lingbao or magic weapon, there is an instrument spirit, which involves the process of sealing the spirit. It is not so simple. It may take more than ten years for an old monster in the golden elixir period or the Yuanying period to refine a magic weapon level flying sword.

"What style of flying sword do you like? Lin Feng, I've never seen what a flying sword is like. What do you want me to choose? " Li Yutong smiled, waved his hand and said, "you'd better decide by yourself!"

"Why don't you know? Sister Tong Tong, haven't you seen a pig run without eating pork? You haven't seen the real flying sword. Haven't you even seen the flying sword in those fairy tales on TV? "

Lin Feng controlled the sword embryo, slowly pulled out the sword body with his spiritual knowledge, and asked Li Yutong, "otherwise, sister Tongtong, tell me what kind of pattern you like? Anyway, the body of the sword is similar. It's the style of a sword. The key is the style and pattern of the hilt. "

"Patterns? Then I'll use my cell phone to search for you... "

With that, Li Yutong picked up his mobile phone and found several patterns. Lin Feng thought it was very good, so he added it to the hilt of the flying sword according to the above pattern.

Time passed hour by hour. It was strange that Li Yutong had been refining flying sword with Lin Feng, and he didn't feel sleepy at all.

Melting materials is the first step in refining flying sword. The second step is the most critical step, which is to carve the array in the sword embryo, and the last step is to shape the sword body, which is also the most cumbersome step.

Of course, the third step doesn't take much time if you don't have to be too beautiful and can use it casually. However, this is the first flying sword refined by Lin Feng, which was refined together with Li Yutong. Naturally, you can't be so casual. After studying some pictures of flying swords on the Internet, Lin Feng chose to carve a dragon pattern and a phoenix pattern on the handle of flying swords, which is equivalent to the meaning of dragon and Phoenix singing Yin and Yang.

In this way, some edge and corner patterns were engraved on the sword body, and these array methods of gathering souls were attached to it. In this way, the shape of the whole flying sword was completely completed.

It took nearly an hour to melt the materials, two hours to carve the array, and three hours to shape the shape of the flying sword. After Lin Feng's Dragon and Phoenix and mighty flying sword were fully formed, it was more than five o'clock in the morning, and the East had turned white.

"Hoo! Finally, sister Tong Tong, you can try our flying sword! "

After completing the last step, Lin Feng suddenly shook the flying sword, the vitality in his body moved, and then there was a clang sound.
