Spending the night in an area where extreme cold is ubiquitous not only requires guarding against strange and snowy mountain nightmares, but the biggest trouble is maintaining a thick layer of True Qi protection even when you sleep.

In this world, Zhou Fan had never seen a martial artist sleeping and still maintaining a thick layer of true qi protection.

Zhou Fan tried it and found it difficult to do it, because once a person falls asleep, he can't maintain the operation of his true qi as he did when he was awake.

When attacked, the True Qi can operate freely, and many martial artists can do it, but the attack of the cold Qi is very hidden, and it will not activate the operation of the True Qi.

And it is very difficult to sleep and maintain the operation of true qi, at least Zhou Fan doesn't know how to do it, he has no experience in this area.

In addition to this, there is a second tricky question: who will keep vigil for him after he sleeps?

In that weird, cold and ubiquitous environment, he didn't dare to let Xiao Xuan come out to keep vigil for him.

If he was in an ordinary wilderness, he could just lay a rune array, and once a monster tried to impact the rune array, even if he was in the gray river space, he would be able to wake up immediately.

But the Thousand Illusion Snow Mountains are different, the Ring of Horrible Dreams is everywhere, even in this extremely cold area, it is very likely that there will be a Ring of Horrified Dreams.

Once he falls into a nightmare, even if there is a strange impact talisman array, he will probably not be able to wake up from his deep sleep, and then he can only be slaughtered by the monster.

Faced with these problems, Zhou Fan raised his eyebrows slightly.

He thought about it for a while, and first slowly weakened his True Qi defense layer by layer.

As the True Qi defense weakened, Zhou Fan soon discovered that a wisp of cold qi had invaded his body.

This wisp of cold qi was extremely small, and if it weren't for Zhou Fan's concentration on his body, it would be difficult to find it.

After this wisp of cold qi invaded, Zhou Fan quickly improved his true qi defense, isolating the cold qi that other people wanted to come in outside.

He adjusted the dragon god's blood that tried to kill the cold qi, and just wrapped the cold qi with the dragon god's blood.

The wisp of cold air was surrounded by the blood of the dragon god, and it was suspended and could no longer move.

Zhou Fan raised his eyebrows slightly, and he grabbed a wisp of cold blue flame and covered it with the cold air.

But the cold blue hot yang qi was quickly extinguished by the cold air.

Zhou Fan was not in a hurry and continued to absorb the hot yang qi in his body, and the wisps of hot yang qi and the wisps of cold qi killed each other.

It wasn't until there were a total of three wisps of Yan Yang Qi that the wisps of cold qi were completely killed.

After that, Zhou Fan used the method just now to put in a wisp of cold air, this time using a qi ghost, he found that the qi ghost and the wisp of cold did not interfere with each other, even if Zhou Fan ordered the qi ghost to eliminate the cold qi, the cold qi could not help the qi ghost.

This strange phenomenon made Zhou Fan a little puzzled, but he didn't think much about it, but withdrew the qi ghost and used the empty sound ghost thunder.

A wisp of thunder arc can extinguish a wisp of cold qi, but after the black thunder arc extinguishes the cold qi, there is very little power left.

This made Zhou Fan breathe a sigh of relief, he was going to choose the empty sound ghost thunder to deal with the weird cold qi when he fell asleep, and the hot yang qi was kept as a second backup.

In fact, the dragon god's blood is the most suitable, because the dragon's blood will be automatically activated, and the dragon's blood is very strong, no matter how much cold qi comes, it is not an opponent.

But if the dragon god's blood is consumed overnight like this, it will take a long time to recover.

This is not conducive to Zhou Fan continuing to climb up tomorrow, because the blood of the dragon god is too important, involving his talent for dragon god language and the ability to quickly recover his true qi.

This may be the key card that can determine the outcome in battle.

If it wasn't necessary, Zhou Fan didn't want to consume the dragon god's blood, which was also the reason why he would rather trouble using some true qi to resist the weird cold qi than use the dragon's blood when he climbed the mountain before.

On the contrary, the importance of the Empty Sound Ghost Thunder and Flame Yang Qi is not as important as the Dragon God Blood, even if it is consumed too much, Zhou Fan has other means to make up for the lack of attack.

Of course, there is also a problem with using the Empty Sound Ghost Thunder and Flame Yang Qi, that is, these two forces will not automatically attack the weird cold qi that has eroded into the body, unless the cold qi attacks them, they will fight back.

But this was not a problem for Zhou Fan, he moved his mind and communicated with Xiao Xuan in his body.

"Xiao Xuan, when I sleep, you mobilize the empty sound ghost thunder and hot yang qi in my body to deal with the cold qi that erodes in, and give you three chicken legs and three duck legs, do you know?"

"Got it, master. Xiao Xuan responded happily.

Zhou Fan gave a few more words of advice and taught Xiaofei how to do it.

After disconnecting from communication with Xiao Xuan, Zhou Fan was relieved, as long as Zhou Fan gave up control of his body, Xiao Xuan in his body could mobilize part of the power of his body.

It's a pity that it's difficult for her to master the huge amount of true qi, otherwise it would be better to directly let Xiao Xuan transfer the true qi to resist the cold.

Nothing is perfect.

In order to avoid accidents, Zhou Fan first cautiously withdrew his true qi defense and let the cold qi erode in.

The dragon god's blood was still the first force to react, and it didn't hesitate to rush towards the strange cold air.

But under Zhou Fan's relinquishment of control over his body, Xiao Fei first ordered the dragon god blood to retreat, called out the black thunder arc hidden in the bone marrow, and slaughtered all the cold qi, and quickly eliminated the invading cold qi.

There is a constant invasion of cold air, and the black thunder arc continues to destroy the invading cold air.

At first, Xiaoxuan was a little scrambling, but she quickly got used to it.

While looking inwardly at the changes in his body, Zhou Fan estimated that if nothing abnormal happened, the empty sound ghost thunder stored in his body would be enough to maintain a night's consumption.

The problem of cold can be said to be solved.

Zhou Fan regained control of his body, and after he used the Empty Sound Ghost Thunder to eliminate the cold qi in his body, he used his true qi to isolate the invasion of the cold qi.

Then came the second problem, the problem of him being stuck in a nightmare and not waking up to a strange invasion.

Last night, Xiao Xuan was able to guard him and defend against monsters, even in terms of resisting the invasion of monsters, how much role Xiao Xuan could play, Zhou Fan had doubts about this.

But now that even Xiaoxuan can't come out, the situation has become more dangerous.

Zhou Fan pondered for a moment, he took out the storage book from the talisman bag, "Open the storage book." ”

"Little books serve respected book lovers, what is the most important thing for someone who plans to keep their hair around their waist?" said the cheerful voice of the storage book.

"Master, you tell Xiaoshu for me, the answer is, first, he must have hair. Xiao Xuan's voice echoed in Zhou Fan's body.

The Book of Storage couldn't hear Xiao Xuan's voice, so he was still waiting for Zhou Fan's answer.

Zhou Fan's face turned dark, is this a mockery that I don't have hair? Xiaoxuan, your chicken leg and duck leg are gone.

Zhou Fan thought so, but he still sighed and said the correct answer: "Don't go out in white clothes at night." ”

"Congratulations to those who love books, the answer is correct, and the book of storage is ready to be opened. ”
