Before putting Xuantian into the test, the "Heart Sword" book spirit spoke out again: "Xuantian, the firmness of your mind is rare in the world, but you need to remember the four words step by step, don't be in a hurry. It is not easy to practice this exercise, and it is common for progress to be slow, and once you have the idea of being greedy and insufficient, you will immediately be in danger of going mad. If you feel overwhelmed in the midst of a trial, speak up and signal to me, and I will take your consciousness out of the testing area. ”

Xuantian was suspicious: "Does quitting in the middle of the test mean that the attempt is considered a failure and needs to be started all over again?"

"Not bad. However, since you can't make it to the end, it means that your mind is not strong enough and needs more training. The book spirit affirmed Xuantian's judgment.

Xuantian bowed his head slightly to show his understanding, and said: "I have my own measure, my seniors don't have to worry, and I ask my seniors to arrange tests for me." ”

Xuantian's voice fell, and the original pure white void space around him changed, although the color in the environment did not change much, but at this moment, the endless white in Xuantian's vision had another meaning, making him immediately understand the situation he was about to face.

In the vast expanse of glaciers and snowfields, the cold wind is fierce, and the howling sound is like a wolf's howl. Frozen for thousands of miles, all the liquid existing in this space has condensed and no longer has the right to flow, and the rivers, lakes and seas seem to have turned into extremely heavy ice mounds. The snow is white, and the mountain peaks are covered with thick frost and snow without exception, and there is no shadow of the original strange rocks, as if it was originally made of countless snowflakes.

Xuantian stood in this boundless world of ice and snow, and his whole body was already trembling. Usually with Xuantian's cultivation, even in the depths of winter, even outdoors in the depths of winter, with only a single coat, it will not feel cold. However, now that he had just entered this space, Xuantian could no longer stand the cold, and the idea of escaping rose in his consciousness.

As soon as this thought appeared, Xuantian immediately stifled it, trying to make his divine consciousness more sober, and a feeling of worry welled up in his heart.

"Before the test officially began, I was about to be unable to bear it, and besides, this was only the first test, and it seemed that the cultivation of this 'Heart Sword' was much more difficult than I imagined. ”

The voice of the book spirit interrupted Xuantian's thoughts, and he had to face a severe test.

"This first level is called 'Deep Cold', and the main purpose is to train the divine sense to resist the cold environment. As soon as you are ready, I will start this test for you. Every time a snowflake falls, the space will be colder, and an hour later, the temperature will be similar to that of the North Julu Island Polar Region. As long as you can persevere until that moment, it means that you have successfully passed the first level. ”

Xuantian gasped unconsciously when he heard this, Beiju Luzhou was already inaccessible due to the temperature being too cold in the north, and when he reached the extreme north, the temperature was already below zero and more than 100 degrees, it could really be said that there was no grass and lifeless, and almost no creature could stay there for more than a moment.

Feeling the resistance from the depths of his heart, Xuantian hurriedly calmed his mind and drove all the superfluous distractions out of his mind. Xuantian secretly told himself that if he hadn't tried yet, how did he know that he would definitely fail? If he couldn't even show this courage, he was afraid that his cultivation would stagnate forever.

Xuantian's autosuggestion really worked, the fear in his heart gradually subsided, replaced by an indomitable belief, he no longer hesitated, and said loudly: "I am ready for the next, and I ask the seniors to start this test for the next." ”

"There have been a lot of talented people in this space, but very few have decided to take on the challenge. This courage alone proves that your future is limitless. I have opened the test for you, and how well you can persevere depends on your own perseverance. The words of the book spirit were full of appreciation.

Xuantian concentrates his mind as much as possible to calm his mind and reduce his sensitivity to external influences. The cold that permeated his body was suddenly relieved, and the shaking of his body gradually stopped.

Just when Xuantian thought that he was on the right track, his body suddenly sent a dangerous signal to his mind.

The snowflakes are crystal clear, and pieces of goose feathers continue to fall from the sky, seemingly never stopping, and the temperature plummets sharply with the falling snowflakes, and the space is several times colder than before with just a cup of tea.

Although it was only Xuantian's divine consciousness that entered this space, in order to facilitate the implementation of the test, Xuantian's body form was still "restored".

A thin layer of frost floated on Xuantian's skin at this time, obviously the blood in his body could no longer withstand the biting cold, and began to gradually solidify, and then formed traces like shallow frost.

The trembling that had just calmed down was even more intense at the moment, and the body trembled as if it was an instinctive reaction, as if it wanted to offset the cold caused by the erosion through the heat generated by the exercise.

Xuantian didn't decide to expel the cold through exercise, because it was only a temporary relief, and the result of wasting energy for no reason was to lose the motivation to support it at the moment when his physical strength was exhausted.

Xuantian sat down on the spot, and used the true qi of his whole body to form a barrier around his body, and tried his best to resist the cold qi invading the meridians around his body.

After comprehending the realm of "the unity of heaven and man", Xuantian finally understood the method of casting the true qi barrier, and once it was used at this moment, it immediately had an effect.

The cold air was all excluded from the barrier, and the space inside it returned to its normal temperature, and the frost on the surface of Xuantian's skin had all faded, and the situation seemed to be very good. However, only Xuantian himself knew that this was nothing more than a battle of trapped beasts, and the consumption of energy by the True Qi Barrier was also a lot, and it could only support the time of a meal at most. As soon as time passes, not only does the barrier fail, but the body also enters a state of prostration, as if exposed to this extreme cold, defenseless, I am afraid that it will immediately fall into mortal danger. But with Xuantian's current cultivation, there is no other way but to fight hard, and the dead horse is regarded as a live horse doctor.

The snow still kept falling, and the time of an hour was gone.

The True Qi barrier around Xuantian's body was already extremely thin at the moment, and only faint traces of True Qi flow could be seen, between existence and disappearance.

True qi and energy are passing rapidly, Xuantian can feel that he is already at the end of the strong crossbow, even so, he has to do his best to hold on, and if he can hold on for one more second, he will be one step closer to success.

Xuantian's face was as pale as paper, cold sweat from the corners of his forehead couldn't help dripping downward, and his lips were already dark purple, and he was only one step away from the collapse of his whole body, maybe it was the next moment.

For others, time flies and passes in a flash, but for Xuantian, it is the complete opposite, every minute and second is torment, and every moment is like being in purgatory. Xuantian now finally understood the meaning of living like a year, and hoped that time would not stop at this hour again, so that he could get out of this boundless predicament immediately.

Heaven never seems to grant a man's wishes, and no matter how tenacious he is, he can hardly afford the limits of his physical strength. There was still half a pillar of incense time before an hour, but Xuantian's true qi and energy had been exhausted. The barrier disappeared into the void, exposing him to the deep cold that was already indistinguishable from the extreme north of the North Julu Continent.

Suddenly, Xuantian felt a deadly threat.

The weakened body was unable to resist the invasion of cold qi at all, causing it to travel through the pores to every corner of the blood veins, further blocking the little true qi and physical strength left in Xuantian's body, causing Xuantian to lose the last trace of strength to struggle.

The blood gradually coagulated, the veins slowly froze, and the system in the body that should be circulating was completely destroyed, and the functions of the internal organs could no longer be maintained, and they were on the road to failure.

When the last ray of hope is gone, the heart seems to be frozen in layers. Xuantian could even feel that his consciousness was slowly separating from his body, gradually throwing himself into the endless dark abyss, this was the first time in his life that he felt so close to death, as if he could touch the door of the underworld with his hand.

Layers of frost continued to grow on Xuantian's body, and in an instant, it was all over the body, and the frost continued to expand, gradually forming a smooth plane, but after a while, Xuantian was frozen into a huge ice sculpture, and his appearance and body on the ice sculpture were all lifelike, like the proud work of a master sculptor.

The voice of the book spirit echoed in this space again, and it seemed that there was still a hint of anxiety.

"Xuantian, respond quickly when you hear my voice, and if you don't hear back, I will forcibly stop the test and rescue you from this space. ”

Xuantian's divine consciousness on the edge of darkness vaguely heard the call of the book spirit, and instantly regained a trace of consciousness, and an incomparably familiar voice echoed in his mind, hovering in his ears incessantly.

"You are the most outstanding genius I have ever met, and I firmly believe that there is nothing in the world that you cannot do. ”

"I know you're going to live up to anyone's expectations of you. ”

It was cool and tactful, like the sound of the heavenly fairy sound, but at this moment, it was like a heavy hammer that slammed into Xuantian's heart, making Xuantian instantly forget all the exhaustion and despair.

That incomparably firm expression and the beautiful smile that can make a hundred flowers bloom like a spring breeze have left an indelible mark in Xuantian's mind.

"If I bow to difficulties, if I allow my consciousness to fall into a drowsiness, how can I be worthy of her unhesitating and consistent trust?"

A majestic golden light suddenly broke through the ice and rose straight into the sky. In an instant, the snow melted, and there was an incomparably hot breath between heaven and earth.
