An hour passed, and the sword embryo gradually took shape, and then on the flying sword, I put some attack and defense formations that I thought were good, and played a weapon trick to make the flying sword completely formed. In the end, Chen Nan bit the tip of his tongue and spurted out a mouthful of essence blood on the flying sword, and suddenly a feeling of flesh and blood was born out of thin air, as if this flying sword was a part of himself.

Put away the fire in the center of the earth, and there was a blood-colored flying sword half a foot long, thumb-wide, and awe-inspiring killing intent floating in the air, and this blood-colored flying sword was even more chilly.

As soon as his divine sense moved, a blood rainbow crossed the void, with a frightening coldness and killing intent, looking at the flying sword he had worked so hard to cultivate, Chen Nan nodded with satisfaction.

"It's done, Lao Tzu will also have his own natal flying sword in the future!"

The flying sword needs to be nourished with essence blood to be more powerful, and it can be more convenient to use, Chen Nan did not hesitate to open his mouth to put the flying sword into his mouth, this flying sword is like his flesh and blood, it can change into any shape in the abdomen, and there is no need to worry about hurting himself at all.

Finally, Chen Nan also had to refine a flying sword, which was mainly made of branches of the Heavenly Sacred Tree and Blood Jade Cold Ice Stone.

Before refining, Chen Nan first summoned the Jiaolong Soul out, looked at him and said with a smile: "I want to refine a flying sword for my woman, because he can't cultivate, so he can't resist the sword himself, I need a tool spirit, are you willing to be my weapon spirit?"

Once the flying sword has a spirit of the instrument, it becomes a real spirit weapon, and although the few flying swords just now have reached the level of a spirit weapon, they do not have a spirit of the weapon.

The flying sword with the spirit is more powerful than the ordinary flying sword, in addition to the master can be manipulated, the most important point is that the spirit can automatically protect the master, once there is danger, you can protect the master independently without the drive of the owner, although Chen Nan does not understand the refining method of this spirit weapon, but if Jiaolong is willing to be a tool spirit, then it is much easier to refine this sword.

"I ......" Jiaolong was speechless for a while, wanting to refuse, but Chen Nan saved his life, not to mention, he used soul nourishing beads and his own blood to nourish himself, although the fierce but upright Jiaolong didn't know how to answer for a while.

Chen Nan waved his hand, "Don't be embarrassed, if you are willing to be a machine spirit, I will smelt a drop of my own essence blood into it to warm your soul, one day in the future, if I can achieve the Great Dao, I will definitely help you recover your body and become an immortal, if you don't want to, I won't be reluctant!"

Chen Nan thought very clearly, he had to be willing to protect Concubine Nalan Ruo, after all, Concubine Nalan Ruofei couldn't cultivate, and he was really worried that something would happen to Nalan Shiyu if he couldn't control the dragon.

"I do!" replied immediately.

Warm with essence blood, he has already felt the unusualness of Chennan's essence blood for several months, not to mention the precious innate earth essence in it, and there is also a covetous chaotic aura, which is also a dream for those powers.

In Jiaolong's view, it can be said that it is a sure thing to have Chennan's essence and blood to nourish his soul, recover his body in the future, and achieve immortal status, not to mention that Chennan also made a promise to him personally. There are ancestral ginseng and Tongtian holy trees around him, all of these are things that make the immortals crazy, can such a person be poor in the future? So Snake Jiao agreed to be a machine spirit without hesitation.

"Okay!" Seeing that Jiaolong agreed, Chen Nan immediately began to melt the materials, smelting the divine wood and blood jade Xuanbing stone into the shape of a wooden hairpin, and then sealed the Jiaolong soul into it, and then dripped his precious life essence blood into dozens of attack and defense formations.

The life essence blood is at the cost of consuming people's longevity, which also means that if he can't step into the dragon realm, his lifespan will be shortened, but for the sake of his wife's safety, he doesn't care about this at all.

He is not afraid of what moths will come out of the dragon, with his own life essence and blood, the dragon has his own spiritual imprint in his soul, and he can be wiped out in a single thought.

Punch into the magic trick to make the flying sword take shape, a shape like a phoenix hairpin, a crystal clear wooden hairpin quietly floats in front of him, a dragon phantom in the wooden hairpin spits clouds and mist, hovering in it, this is a veritable spiritual weapon, is a flying sword.

In the eyes of ordinary people, this is an elegant and noble wooden hairpin, and no one would have thought that this would be a spiritual flying sword.

Stretching out his hand, a three-zhang long blue light crossed the void, and a dragon swirled in the blue light, an invisible coercion made the void tremble.

"What a powerful momentum!" The power of this flying sword is beyond imagination, and Chen Nan was stunned when he saw it, but in this way he was more satisfied.

Reaching out to beckon the wooden hairpin that was only one finger long back into his hand, Chen Nan couldn't put it down, and he was quite satisfied with his creativity, after all, he didn't have any worries about protecting his wife.

After recovering his lost true qi slightly, Chen Nan dragged his tired body out of the Qinglian World. Outside the cave, the two sisters were playing with duck eggs, ancestral ginseng, and leopards on the grass with the scent of green grass, and the sound of giggles kept coming, and it was obvious that the two daughters were having a great time.

"Husband, are you out of the customs?" Nalan Shiyu saw Chen Nan come out and flew over on a little cat, and now the leopard has recovered and can change the size of its body at will, so she naturally uses it as a mount.

Seeing her brother-in-law out of the customs, Concubine Ruo also twisted her little buttocks, and ran over with the twin peaks bumping and undulating.

"Concubine Ruo, I have a gift for you!" Chen Nan shook his hand, and a small flying sword only three inches long and one finger wide was suspended in the air.

Concubine Nalan Ruofei stepped forward to pick up the flying sword, looked at the flying sword with a pair of wings, and the water was rippling, she couldn't put it down, and asked with her big eyes: "Brother-in-law, is this my flying sword? Why is it so small? Can I fly with a sword?"

"Of course, it's enough to put your divine sense imprint into the flying sword!" Chen Nan said with a smile, and passed on another set of sword magic techniques to her.

Concubine Nalan Ruofei marked her divine sense in the flying sword, and said happily: "Brother-in-law, can I try the power of this sword?"

"Silly girl. Chen Nan smiled and pulled her long hair, "It's your flying sword now, of course you can manipulate it at will." ”

"Hee-hee!" Concubine Nalan Ruofei giggled excitedly twice, glanced at a small hill ten zhang away, pinched the sword trick in her hand, and said lightly: "Go!"

The flying sword flew towards the mountain peak with a long red light, "Boom!" The mountain peak was cut off by the sharp sword qi, and the rocks flew with a loud roar. Concubine Nalan Ruofei ran over to take a look, and the small hill was as smooth as if it had been cut by a knife, and the flying sword slashed the hill like cutting tofu.

The two sisters' eyes widened, they never thought that a seemingly inconspicuous small sword could be so powerful.

Looking at the sword light hanging in the air, Nalan Ruofei's heart moved, the small flying sword turned into more than three feet long, Nalan Shiyu soared up, and a brilliant neon appeared on the sword body, wrapping her in it and hovering in the air.
