However, this time Nie Fei's situation was different. Just as he thought, he passed guò caustic soda, and the dark red smoke that he dissolved was the yang energy in the sunflower. The yang energy was completely dissolved by him, and what was left was pure and incomparably cold. The small sip of liquid he drank, although it was not much, contained more cold than the cold in a thousand sunflowers. How could he stand the cold so much? In fact, the correct way to drink this pure cold should be that he could only drink one or two drops when he drank it for the first time. After it is completely absorbed, the aura has the basis of cold qi, and when you drink it in the future, you can increase it as appropriate. If you want to drink a small sip of Cheng dù at a time, you must at least gradually cultivate for more than half a year. Or after he reached the seventh level of qi refining, he could also take such a small sip.

How did Nie Fei know about these things? In his aura, there was no cold qi foundation, and his aura level had not reached the seventh layer of qi refining, but only the fourth layer of qi refining, which was 108,000 miles different from the seventh layer of qi refining. But he drank too much by mistake, and the pure cold air in the sunflower didn't cause a catastrophe.

Now, it can't be blamed that Nie Fei can't think of a way, there is really no way. What awaited him, perhaps a few days later, was when someone who came to visit him by chance found his body frozen like a piece of ice. That person may also secretly wonder, how could this Young Master Nie be frozen to death on this hot day? That must be the heavens that opened their eyes, and the heavens sent divine punishment to remove this harm for the Heavenly Spirit Castle. Otherwise, how can we explain that Nie Fei was frozen to death?

......

Nie Fei's consciousness seemed to be frozen, almost completely lost, but after all, it was not completely lost. The aura is also the same as his consciousness, almost frozen, but after all, it is not completely frozen, and there is still a trace of residual aura circulation in his body. In Nie Fei's subconscious, he only felt an indescribable coldness all over his body, and he just wanted to be warmer.

Almost subconsciously, Nie Fei used the palm fire technique. Fortunately, the various veins of this palm fire technique were not frozen to death by the cold, and they could barely function.

A cluster of bean-sized flames appeared in Nie Fei's palm. In fact, according to Nie Fei's aura level, if you use the palm fire, the entire palm will be covered by flames. But most of his aura can't function now, and his veins are quite severely blocked by this cold qi, so he can barely gather this small cluster of flames. This cluster of flames was even inferior to when Nie Fei was refining Qi at the first level.

Nie Fei slowly raised his stiff hand to his chest. This is an action that would normally be easy, but at this moment, it is really as if it is paralyzed, and it can only move point by minute. I don't know how long it took, Nie Fei gritted his teeth and stiffened, before he moved his hand to his chest and pressed his backpalm on his chest.

The bean-sized flame didn't emit much heat, and Nie Fei's feeling was like using an oil lamp to melt an iceberg, and it was a dream to rely on this flame to expel the cold in his body.

Don't look at the flames are very small, but after a long time, they also have some effects, and after a long time, Nie Fei felt that his chest was not as cold as before, and there was a little warmth. As soon as the chest was relieved, even the flame of the palm fire seemed to be a little stronger, so Nie Fei used this flame to bake his abdomen. In this way, little by little, he successively expelled the cold qi of the chest and abdomen and the sea of qi in the lower abdomen. At this time, the flames are more vigorous, and when it dissolves the cold in the limbs and back, it is much faster than before.

It wasn't until dawn on the second day that Nie Fei dissolved all the cold in his body, and finally crawled back from the line of life and death.

Nie Fei sat up slowly from the ground, his heart still lingering about last night's danger, if he hadn't thought of using the palm fire technique to dissolve the cold, I am afraid that he would really die this time. This accident also taught him that in this immortal cultivation world, nothing should be sloppy, otherwise if he is not careful, he is likely to die again.

......

Nie Fei rested for a while, studying the cold qi in his body.

Through guò introspection, he had already discovered that at this time, the aura in his body contained a sense of coolness, and the feeling was extremely comfortable, as if a clear spring was flowing in his body. Nie Fei guessed that the coolness in the aura should be the cold qi. Earlier, there was none, but since drinking the medicinal liquid of the sunflower, the aura contains coolness.

Since the aura contained cold qi, Nie Fei couldn't help but want to try it and see what kind of effect this cold qi had. Of course, if you want to see the effect of this cold qi, you have to start with the Water Thousand Illusion Exercise. The Water Thousand Illusion Technique can conjure up water vapor, and then he injects cold air into the water vapor, so that the water vapor can be condensed into ice, turning the void into reality.

Thinking of this, Nie Fei raised his aura and performed the Water Thousand Illusion Technique. The aura in his body, after running in a circle according to the veins referred to by the exercises, rushed out of his body from his palms, and almost instantly, the water vapor changed into a long sword. At this time, Nie Fei realized that although the cold qi was mixed with the aura, the veins they traveled were different, and the cold qi had its own veins. So, Nie Fei urged the cold qi again, causing it to melt into the long sword that was transformed by water vapor.

Hearing a click, the long sword slowly condensed into ice from the hilt to the tip of the sword, and almost in the blink of an eye, an ice sword made of cold ice was suspended in front of Nie Fei's eyes. When Nie Fei saw the cold ice, the blade of the sword flashed with cold light, and he couldn't help but be surprised and happy. With a thought, he swung his ice sword and slashed at a thick tree beside him. There was a pop, and Nie Fei saw that the ice sword slashed into the trunk of the tree about two inches deep, and then the ice sword shattered, turning into fine ice crystals, like stars in the sky, fluttering and falling to the ground.

Although this ice sword had not cut down the trees, Nie Fei was already very satisfied. Being able to cut into two inches deep, the power of this ice sword is already extraordinary, Nie Fei believes that as long as time passes, when he absorbs the cold qi and gradually increases, making the conjured ice sword stronger and sharper, it will only be a matter of time before he cuts down this big tree.

......

At that moment, Nie Fei came to the table, stretched out his hand and grabbed the jade bottle from the sunflower liquid in his hand, looked at the jade bottle twice, put the mouth of the jade bottle to his mouth, and drank some medicinal liquid.

This time, he was afraid of another accident, so he didn't dare to drink more, and only drank a dozen drops. In the mouth, there is a bitter taste, but in this taste, there is a coolness. The liquid slid down his throat and into his abdomen, like ice water, cooling from his throat to his abdomen.

Nie Fei didn't dare to slack off, so he quickly sat down and used his luck to absorb the cold qi. This time, he drank a moderate amount of medicine, and after the liquid medicine was put into his abdomen, he did not show any discomfort. By the time he had completely incorporated the cold qi in the dozen drops of medicinal liquid into the sea of qi, two hours had passed.

Nie Fei stood up and introspected again, only to feel that the coolness in the aura seemed to be even colder. It can be seen that although it is a dozen drops of medicinal liquid, the cold energy contained in it is not a few.
