Xiang Nan waved his hand: "If you still tell me this, it's too outward." ”

Ru Yan shook her head seriously and said: "No, if you save Yu'er, it is equivalent to saving my life! Such a great kindness, Ru Yan will never dare to forget." ”

"There are three messengers, all of which are infused with my blood and vitality, and you can send me a message at any time. ”

Xiang Nan took the messenger, solemnly put it away, and said, "Go, hurry up and use the pill for Xiao Yu'er, I also have to go home." ”

The two were separated in the manor, and Xiang Nan was given a horse chasing the wind and hurried back to Qingshi Town.

Chasing the wind horse, a congenital demon beast, can make good use of demon energy for long-distance galloping, the speed is comparable to the rapid running of a martial artist in the innate realm, and it is a very expensive thing.

In particular, this wind-chasing horse has a strong body, with two feet long from head to tail, eight feet high from hooves to back, and the whole body is pitch black, and it is majestic.

Xiang Nan rode away on a chasing horse, only to feel that the scenery on both sides was rapidly regressing.

After returning to Xiang's Mansion, he first took a brief look, and then chatted with his mother for a while, and then hurried to the Heifeng Mountain Range.

The Xiang family's industry is rising in an orderly manner, and Xiang Nan doesn't have to worry about this, what he needs to do most now is to find a place where no one is there and improve his resistance to electricity.

The mountains of the Black Front.

Here, Xiang Nan easily found a place that was inaccessible.

Once he had laid out the applications he needed, he took three deep breaths in a row: "It's time to begin." ”

"Hopefully, this time, I can get a big improvement, and it's worth my hard work to search for materials. ”

After seeing that there was no one around, he used a three-meter-huge black scale heavy knife to dig a large pit in the ground that was twenty meters deep, and this pit had already penetrated deep into the mountain.

Then, he put the furnace into the pit, jumped into the furnace himself, and buried the earth above it in the weather.

Sure that he was safe and sound, Xiang Nan nodded with satisfaction, he put himself in the darkness inside the Dan furnace, and first put a stone skin pill into his mouth.

"That crazy alchemist said that refining the martial artist itself as an elixir can get unexpected results. ”

"Hopefully he's right. Xiang Nan was a little uneasy in his heart, but the matter had come to this point, and there was no way to turn back.

He slapped the inner wall of the Dan furnace with both hands, and the fire in the Dan furnace suddenly burst into flames.

A human being, even if he is an Innate Realm martial artist, will not be able to survive if he is in the flames like this.

Therefore, Xiang Nan used the Stone Skin Pill, which was extremely effective, so that Xiang Nan's skin was petrified within the next full hour, so as to ensure that he would not be burned to death.

Then, there are various other spiritual herbs, which are either swallowed in an orderly manner or used to smear the body.

Rao is like this, with the increase in the progress of body refining, Xiang Nan also began to feel hot in his body, and the feeling of suffocation became more and more serious.

Fortunately, with the help of the Rejuvenation Pill, the strong medicinal properties freed him from his dependence on air, and the snow cicada grass cooled his body.

Finally, there is the three-rank thunderbolt vine.

Plants have an incomparable tolerance to nature, and they can be found in almost every corner of the world, and they can adapt to any harsh natural environment.

And the thunderbolt vine is a special spiritual grass that grows up in the baptism of thunder and lightning all year round.

This time to refine the body, Xiang Nan slowly integrated the electric resistance carried by the thunder vine itself into the flesh and blood of his human being.

The flames in the Dan furnace became more and more violent, Xiang Nantong's body turned red, like a humanoid sculpture that had been burned red, and the resistance to electricity of the thunderbolt vine penetrated under his skin, entering the essence of his bones and internal organs.

At the end of the practice, Xiang Nan's whole face glowed red, he gritted his teeth, endured unimaginable pain for ordinary people, and said in his heart: "It's almost over, it's almost over." ”

"The hundreds of bones around the body have almost been trained, and in the end, only the dantian and meridians remain. ”

At this time, there are still ten minutes of action time left for the stone skin pill.

The powerful resistance of the thunderbolt vine swam rapidly in Xiang Nan's body, and Xiang Nan's eyes suddenly opened, and a flash of electric light flashed in his eyes.

The power of thunder and lightning was stimulated by him to the limit, and suddenly there were arcs of lightning that were difficult to see with the naked eye, enveloping Xiang Nan's whole person.

It started from the dantian with the medicinal properties of the thunderbolt vine and traveled to every bundle of meridian structures throughout the body.

At this point, when the weather had traveled for two days, the medicinal properties of the thunderbolt vine were finally completely absorbed by Xiang Nan.

Rumble!

The top lid of the Dan furnace was opened, and the soil that filled the Dan furnace was directly lifted into the sky, and then a figure rose to the sky!

Xiang Nan landed on the ground with a beautiful turn in mid-air, and in the middle of the ring, the Dan furnace had just been lying in.

"It's done!" Xiang Nan looked at his body excitedly, and he found that his skin had become more radiant and shiny, like a newborn baby.

"I didn't expect that this refining not only increased my electrical resistance, but also eliminated a lot of impurities in my body. ”

Xiang Nan smiled, it seems that this harvest is not small.

Next, it is necessary to continue to absorb the power of the thunder arc of the white flame and thunder.

After he was fully prepared, he threw the thunder talisman into the air, and said to himself: "Every time the realm is improved, the difficulty will increase greatly, I don't know if this promotion, can I jump two small realms in a row like last time." ”

While speaking, he still ran the mantra of the Nine Transformations of Thunder, and the powerful summoning power in his body was summoning Bai Yan Burning Thunder.

In an instant, the thunder talisman crackled, and layers of white lightning visible to the naked eye wrapped the thunder talisman, and the surrounding wind roared, and the trees were all crumbled.

"I don't know what year and month it will be before I can really absorb the thunder source of the burning thunder. Xiang Nan exhaled, and with a casual move, a white thunder arc suddenly flew over.

After the thunder arc touched Xiang Nan's body, Xiang Nan's eyes widened, and a strong electric light flashed in his eyes.

The power of the thunder arc, in less than an instant, completely penetrated every inch of Xiang Nan's skin, muscles, and bones.

"Sure enough!" Xiang Nan snorted in pain, and even his expression was slightly distorted.

This arc belongs to the second channel, and the last time the second channel was completely defeated, and this time, the electrical resistance really played a role.

Xiang Nan could clearly feel the pain he was bearing, but it was much better than the last time! At least his muscles had not spasmed.

The terrifying thunder power contained in that arc was even more violent and mellow than the first one!

"It's on!" Xiang Nan's pupils contracted, and he felt his realm loosen.

Innate Triple ...... Innate Quadruple!

Breakthrough!

"So fast!" Xiang Nan's heart moved, the distance crossed by the three to the four important ones was much more important than the two to three important ones!

Even so, it was crossed so quickly!
