There are very few demon beasts on the northern snow field, but as long as they appear, they are all big demons above the four heavens, and there are even demon kings.

So Gu Xiuyun was cautious all the way, hiding in Tibet with Yan Sushi.

It was two months before they reached the depths of the snowfield.

It was even darker and more silent, as if there was no life, and the biting wind and snow cut through the body like a knife.

The temperature here is already incredibly low, even a Pulse Opening Realm cultivator can hardly withstand such a severe cold, and he needs to use spiritual power to protect his body.

Call!

The cold wind blew across his face, like hundreds of sharp knives scraping, Gu Xiuyun couldn't help but shudder, and looked down at Yan Sushi, only to find that her face was ruddy and there was no coldness.

"The Flame Spirit Vein is really suitable for living in the northern snowfield. ”

Gu Xiuyun continued to walk forward.

In front of him, fourteen spirit tortoise black armor sticks danced endlessly, guiding the way.

After walking nearly a hundred miles, he stopped.

"According to the deduction, the cold jade spirit should be at your feet. ”

Gu Xiuyun urged his refining finger and swung out a sword qi, only to hear a clatter, a finger-sized hole appeared on the ice, and with the power of his sword qi, he could only blast into the ice half a foot deep.

"The ice layer here is inevitably too hard," Gu Xiuyun gasped, "The cold jade spirit is thousands of zhang deep underground, if you want to chisel through the ice layer of thousands of zhang, won't it take a few years?"

Looking at the 10,000-year-old ice under his feet, Gu Xiuyun's eyes rolled, and a thought came to his mind.

"Miss Yan, it seems that if you want to cut through the ice, you can only rely on you," Gu Xiuyun pointed to the bottom of his feet, "The Flame Spirit Vein is the bloodline of an ancient beast, which can melt the ice of ten thousand years, with your current soul power, it must not be difficult to control the spiritual power to merge into the ice." ”

Yan Sushi nodded slightly, trying to stimulate the flame spirit vein.

Soon, a stream of pure spiritual power poured out, following the veins of her body, from the palm of her hand into the ice.

In just a moment, Yan Sushi hurriedly withdrew her palm.

At this moment, her arm was already scorched black, obviously urging spiritual power, which was extremely harmful to her body.

The scorching flame spiritual power fused into the ice, quickly melting a large area of solid ice, taking advantage of this opportunity, Gu Xiuyun continuously urged the refining fingers, instantly tearing the ice several zhang deep.

"Hurry up, the ice here will soon recover. ”

Gu Xiuyun pulled Yan Sushi and jumped into the depths of the ice.

The wind and snow continued on the snowfield, and after half an hour, the cracks were wrapped in solid ice, and there was no sign that anyone had broken through the ice and entered the ice.

After cultivating the scorching sun and pure yang, Yan Sushi's body was extremely resilient, and the scorch marks on his arms could be recovered in just a few hours.

She melted the ice over and over again, and Gu Xiuyun took the opportunity to break through the ice and go deeper.

After half a month, the two finally walked to the depths of the earth.

The ice here was almost dark blue, and the chill was so heavy that even Gu Xiuyun couldn't help but tremble.

In the dark blue ice, there are these fine jade grains.

"Cold jade essence, sure enough, it's here," Gu Xiuyun sighed loudly as he urged his refining finger to take out the jade grains from the ice cube, "With so many cold jade essences, it should be able to suppress the scorching flame spirit vein for a long time." ”

"Gu Xiuyun, this is your goal to go deep into the northern snow field?"

Yan Sushi took a jade grain and looked at it carefully, but she didn't find anything special.

"Miss Yan, if you want to completely solve the calamity in your body, you can't do it by refining your body alone, you must open up the Heavenly Pass in your body and use the Five Elements Heavenly Pass to suppress the Flame Spiritual Vein. ”

Gu Xiuyun said lightly, "And to open up the Heavenly Pass, the biggest problem is that you can't cultivate, as long as you try to breathe in and cultivate, the hot spiritual power in the spiritual veins will instantly collapse the physical body, so you have to take a cold jade essence first to dissolve the heat in the body." ”

"Can it dissolve the heat of the scorching spirit vein?" Yan Sushi was a little unconvinced.

"You swallow one and try it. Gu Xiuyun was full of confidence.

The cold jade spirit has a suppressive effect on the scorching flame spirit vein, which he deduces through the heavenly machine, and there will be no mistake.

Fortunately, the level of these two is not too high, and if he needs treasures such as Huangyang Stone, he will not be able to deduce.

Yan Sushi immediately took a cold jade essence, and as the jade particles entered her body, the chill permeated her body, as if she was going to freeze her into ice.

But then, this chill poured into the depths of the Heavenly Pass, merging with the spiritual veins.

In an instant, the volcano went out, and the flames seemed to be frozen into ice.

The furious heat in Yan Sushi's body disappeared without a trace.

"It seems that I guessed correctly, the cold jade spirit is a deadly poison to others, but to you, it is a life-sustaining treasure," Gu Xiuyun nodded, "You try to stimulate spiritual power, can it operate in your body?"

Yan Sushi immediately ran the spiritual veins, and sure enough, the spiritual power was like gurgling water, surging everywhere around his body, neutralized by the scorching flames and cold ice, and the spiritual power at this moment was pure and unpretentious, no different from ordinary cultivators.

"This state can last for about two hours, so if you cultivate on weekdays, every two hours, you have to take a pill of Cold Jade Essence. ”

As he spoke, Gu Xiuyun took out an elixir and asked Yan Sushi to take it.

The elixir entered her body and quickly turned into mellow spiritual power, making her cultivation rise day by day.

A grain of cold jade essence can only last for two hours, so naturally it can't rely on tuna to improve cultivation, and taking elixir is the best means.

The medicinal power of this elixir is extremely strong, two hours have passed, and most of the medicinal power in Yan Sushi's body is still left, she can only take another cold jade essence and continue to practice.

And Gu Xiuyun also found a place and immersed himself in cultivation.

There are a lot of cold jade essences in the depths of the ice, and the two of them are cultivating separately, and before they know it, half a month has passed.

Bang!

Yan Sushi's spiritual power surged all around her, as if she was in a frenzy, and with the method of breaking the level passed on by Gu Xiuyun, the heavenly pass in her body was slowly refined until it was formed.

Call!

The spiritual power was integrated into the heavenly pass, and then separated from it, but it turned ice blue, as if dyed with a layer of water.

The first heavenly pass of Yan Su's poems is the water walking heavenly pass.

Seeing this scene, Gu Xiuyun smiled.

Water overcomes fire, opens up the water to travel to the sky, and suppresses the scorching spirit veins stronger.

Yan Sushi's luck is good, if the first layer of Tianguan opened up belongs to the wood line or the fire line, her life is already in danger at the moment.

Of course, if it was really those two, Gu Xiuyun would not let Yan Sushi open up the Heavenly Pass, but would only let her continue to refine her physical body until the scorching sun pure yang body reached the third layer.

However, the way of refining the body is extremely time-consuming, and it requires a long period of penance, which is far less effective than opening up the Heavenly Pass.

"Miss Yan, when the Shui Xing Tianguan in your body is completely formed, you will be able to condense the Shui Xing spiritual power, suppress the scorching flame spiritual veins, and the duration of the Soul Suppression Talisman will increase a lot. Gu Xiuyun nodded.

At this moment, the Shui Xing Tianguan has not yet been perfected, and it is impossible to store spiritual power, so Yan Sushi has not changed anything except for the improvement of cultivation, and he still needs to take the cold jade essence.
