"What's the difference?" Chen Cao asked.

"If you are in extreme heat, you are refining your body with fire, and external evils will not invade, your body will be like dark iron, and your heart will be like the sun. The old turtle said: "With the extreme cold as the realm, the heart is like a blade, the mind is like a sword, the inner demon is not born, the anger is like a rainbow, and the momentum is like frost." ”

"To put it bluntly, I don't understand. ”

"Extreme heat is refining the body, and extreme cold is refining the heart. ”

"Feel like the refining body is awesome?" Chen Cao said: "At least this refining body can really feel the changes in the body, but this refining body, the ghost knows if there is any change." ”

"Extreme cold refining can defend the heart demons, and in the long run, extreme cold has more advantages. The old turtle said.

"So it's better to be cold?"

"You can't say that, if you don't have demons, you can't improve your state of mind. ”

"My grass, is it better to be extremely hot or cold?"

"You can ...... it"

"Then can you cultivate both ice and fire?" asked Chen Cao.

"Taoism is the harmony of yin and yang, but in most cases, basically none of the Taoists can finally reconcile yin and yang. ”

"Well, since others can't take the road, I won't take it either. ”

"......" The old turtle looked at Chen Cao speechlessly, and when he listened to the first half, he thought that Chen Cao would say that he wanted to walk away from other people's people, but the second half of the sentence directly admitted: "Actually, it's not completely impossible." ”

"How to get there?"

"First of all, the time limit, thousands of years ago in the world, Hetu was once collected by a Taoist priest, I watched the Taoist priest cultivate step by step, but at that time, when he cultivated to the extreme, he was already a hundred years old, although his spiritual power is the best in the world, but his physical strength has been almost withered, he can't bear the dual cultivation of ice and fire at all, and he can't cultivate the harmony of yin and yang before the limit. ”

The old turtle looked at Chen Cao: "You are different, you are young and vigorous, your physical fitness is even more different from ordinary people, and you have a river map in hand, time is also not a limit for you, so you have a better chance to survive the double baptism of yin and yang." ”

"Is there a risk?" Chen Cao asked.

"There are risks, but the benefits are bound to outweigh the risks. ”

Chen Cao thought about it for a moment: "How long will it take?"

"Then it depends on what package you get. ”

"......" Chen Cao rolled his eyes: "What package do you offer?"

"I'm going to create an environment that is extremely hot or cold for you, and it will take about a hundred years. The old turtle said.

"A hundred years in Hetu, then the outside world is a month? No, if I disappear for a month, it would be strange if Fari didn't go crazy. ”

"Then I will use Heavenly Fire and Xuan Ice to help you transform into poles. ”

"How long will this take?"

"Ten years expected. ”

"Can you stop halfway?"

"Yes. ”

"Then use this. Chen Cao said, "What should I do?"

"I'll create an enchantment between Heavenly Fire and Ice. ”

The old turtle's Fali is thorough, and she is stronger than Chen Cao, I don't know how many times.

The vicissitudes of life may only be in his thoughts.

The sky first fell from the giant pillars of ice, which were of varying sizes and lengths.

The division is in a range of thousands of zhang and circles in a semicircle.

Then the ground began to burn with flames, connecting with the thousand-foot ice barrier.

Ice and fire form a circle, half ice, half fire.

If you look down from above, it's like a Taiji diagram.

As soon as Chen Cao approached the direction of the flames, he felt a heat wave coming.

Chen Cao wanted to change directions, approaching the direction of the ice, and felt a biting chill again.

"What's going on? I'm going to go in and get frozen into ice slag, or I'm going to be turned into a barbecue. ”

"First protect your body with your own spiritual power, then enter from the direction of Xuan Bing, enter the half circle of Heavenly Fire after half a circle, and run as fast as you can. ”

Chen Cao glanced at the old turtle: "Are you sure this is feasible?"

"This is still the outermost layer of cold and heat, the closer you get to the core area of the circle, the more intense the cold and heat become, if you can't even bear this little temperature difference, you better change to the ordinary extreme heat and extreme cold environment. ”

Chen Cao glanced at the entrance, and then at the old turtle.

"Is it all over after a lap?"

"Huh...... In the next ten years, you have to keep running and running, and when you completely transform your spiritual power, you can be regarded as truly completing the transformation. ”

Chen Cao completely mobilized the spiritual power in his body and began to cover the surface of his skin.

Approaching the Ice Realm again, it is no longer as unbearable as before.

Suddenly, the old turtle pushed Chen Cao behind his back.

Chen Cao didn't have time to prepare at all, and the whole person fell into the Xuanbing realm.

At this moment, the entrance to the Xuan Ice Realm was closed.

"If you don't want to freeze to death, run quickly. ”

Inside, the biting chill hit again.

"Old turtle, I'm your uncle. Chen Cao sa girl ran up.

Chen Cao ran as hard as he could, Chen Cao didn't know how fast he was running, he had to leave the Xuanbing Realm as soon as possible.

With a distance of about three kilometers, Chen Cao only took a minute and a half.

At this moment, a heat wave suddenly surged from the place where it docked with the Xuan Ice Realm in front.

Xiang didn't care to think more, and plunged headlong into the passage of the Heavenly Fire Realm.

For a moment, the heat wave in the Heavenly Fire Realm made Chen Cao feel warm, and the chill dissipated.

But in the next moment, the heat wave that burned his skin made Chen Cao unbearable.

The human body's response to heat is stronger than cold, and Chen Cao felt that his hair was about to ignite.

Chen Cao's speed was even faster, passing through the burning Heavenly Fire Domain.

There was a chill in front again, what about the exit?

What about the exit that was originally docked here?

"Old turtle, you old bastard, you blocked the exit?"

"Do you want to be lazy after just one lap?"

There was the cry of an old turtle outside, and Chen Cao ran all the way and screamed strangely.

Rushed into the ice field again, and circled down again.

Walk through the Heavenly Fire Realm, and then through the Dark Ice Realm......

And so on and so forth.

Physically, Chen Cao can bear it, but the consumption of spiritual power can't keep up.

Without the protection of spiritual power, Chen Cao would have to face Xuan Bing and Tianhuo directly.

Finally, when he reached the eighth lap, Chen Cao's spiritual power was completely exhausted.

And the eighth lap has not yet been completed, Chen Cao can only sprint forward.

Finally saw the exit......

Chen Cao rushed out of the exit and fell to the ground, his body covered with frostbite and burns.

"Why do I have to find my own guilt and suffer ......" Chen Cao wanted to cry without tears.

"It's okay, you get used to it slowly, you take care of your injuries for a day, and then you can continue. ”

"Old turtle, why do I feel that you are very enthusiastic about me? ”

"Because it's boring. ”

Chen Cao was very skeptical that the old turtle had come up with this method just to torture himself.

Chen Cao's recovery was very good, and he recovered from his injuries the next day.

Then the second round of ice and fire began.
