After finishing her aunt's class, Su Yan returned to the dormitory and began to work hard to cultivate.

Su Yan had been wandering in the Qi refining period for a few years, and now he had a faint feeling that he was about to break through the foundation building period, and he might be able to cross the foundation building threshold logically after a while of hard cultivation.

In the cultivation realm, the body refining period is to lay the foundation, strengthen one's body and prepare for the qi refining period, so that oneself can better accept the aura of heaven and earth during the qi refining period, and find the aura of heaven and earth that conforms to one's own nature.

And when cultivation reaches the foundation building period, he can truly be called an immortal cultivator.

During the foundation building period, the monks were able to sacrifice and refine magic weapons, and they could also cast spells and arrange formations, and Shou Yuan broke through to the realm of three or five hundred years in one fell swoop, and he was considered to have initially gotten rid of the mortal body and reached the entry standard of an immortal cultivator.

In the normal sect forces, breaking through to the foundation building period before the age of twenty can be called a top genius, and breaking through between the age of twenty and thirty can be regarded as excellent.

Thirty to forty can only be regarded as average, and unless there is any opportunity in the future, there is no hope for the Jindan period.

Because the demon clan is born with a strong physique, it usually takes thirty or fifty years of penance to reach the foundation, and it is even more unthinkable to break through the Jindan period without a hundred years.

This is also why, Su Yan's mother pinched out a human form for him early when she gave birth to Su Yan, so that he could rub the luck of the human race as soon as he was born.

Otherwise, with the particularity of the nine-tailed fox and the true dragon, Su Yan wanted to break through from the Jindan stage to the Yuan infant stage, and it was estimated that it would take three to five hundred years to make it possible, and now if he rubbed the luck of the human race, he could greatly slow down the time of cultivation.

Although it is said to be rubbing, the Terrans have nothing to say.

Because when the demon clan was booming, the human race also came to rub the demon clan like this, and there were not many things that seized the bloodline of the demon clan for cultivation, and even worse things were not uncommon. The division of the nine-tailed fox clan originated from this period, and the clan named the nine-tailed fox of the Tushan clan was separated from the nine-tailed fox of Qingqiu.

And there is the Su clan when the human race is prosperous.

There are four major fox clans in the world, the Qingqiu clan where the nine-tailed fox originated and the Tu Shan clan who assisted the human emperor, as well as the more secular Su clan, and the wild fox family pro-pure fox clan.

If you really want to talk about it, the pure fox clan is the fox clan, and the nine-tailed fox is just a divine beast that looks like a fox, and the fox shape that originated from the fall of the ancient chaos nine stars is not a fox spirit in the real sense.

…………

"Purr ......."

After a night of penance, Su Yan did not continue to maintain his human form, but chose to change into the appearance of a white-haired fox and sleep on the bed.

Because of the weight and the material of the mattress, the only difference between a humanoid sleeping on a bed and sleeping on the floor is probably that it is not as cold as the floor.

It's just that as he tiptoed in, Su Yan felt that his whole body was so cold, and there was a feeling that the ground was shaking like he was on a boat, which made the little nine-tailed fox in his sleep feel as if he was seasick.

Su Yan opened her eyes in a daze, facing a pair of blue eyes, and her own body was rising and falling with her chest between breathing and breathing, and it was not an illusion that Su Yan felt very hot.

Sharks generally haunt the deep sea, and their body temperature changes with the environment, and in general, the body temperature of the mermaids is only one degree or 0.5 degrees higher than the ambient temperature.

It's late autumn, and for foxes, the four-legged pads are used to dissipate heat.

Now the forefoot pad is pressed on the skin of Shark Nanwu, and the hindfoot is stepped on the silk clothes, and the temperature is different when it is originally felt, and combined with the low body temperature of Shark Nanwu, it is like being in an ice cellar for Su Yan.

"Woo ......"

Su Yan shuddered, his forefoot was forced, and he bounced out of Shark Nanwu's body, fell to the floor of the dormitory and turned into a figure, hugged his arms and began to rub them vigorously to increase some temperature.

The feeling of human form and fox form is very different, Su Yan's transformation is worthy of the name, when the nine-tailed fox form, he relies on the tongue and meat pad for temperature perception and heat dissipation, and after turning into a human form, he relies on the skin, like a human race.

"Handicap...... He died of cold. It's like licking on top of an iron block in the middle of winter. ”

Su Yan squatted on the ground and rubbed his skin to warm up, but even so, he still shivered occasionally.

The whole fox is numb, and he doesn't know how long he has been pressed on the shark Nanwu's body before he can accumulate so much chill that he almost froze his entire fox into an arctic fox board......

“？”

Shark Nanwu showed a stunned expression on his face, looked at Su Yan who was squatting on the ground like a ghost, and then glanced at his own thermal insulation suspension and winter nutrition savings board:

"Don't you like that? I remember that the Terrans seemed to be very rare in front of me, and I thought that foxes would like the touch, too......."

"Honestly...... Still like. ”

Su Yan complained in his heart, after all, in a situation like Shark Nanwu, in his previous life, he didn't dare to make such a random P picture, for fear that others would not know about it.

"You're so cold...... My flesh pad is an organ that I sense temperature changes on a daily basis. Su Yan opened his mouth to explain, looked at the shark Nanwu who occupied his bed and asked, "Didn't you say to go home?" Why come early in the morning to disturb my sleep. ”

Last night, Shark Nanwu said that he wanted to go home, and said to the girls in the clan that there are no majestic demon beasts here, so he casually told his family that he was going to spend the winter in Xia Yu.

How in the blink of an eye, she ran back.

"My hometown is in the deep sea......

Shark Nanwu showed an embarrassed expression on his face, and then explained his family situation to Su Yan a little:

"But on weekdays, because of business and trade, we all live in the underground water system, which is only two hundred miles away from the main city of Xia Yu, and it is very fast to come and go, and we only go back to our hometown when the winter is almost over."

The mermaid lives in the underground water system, which is like a trade transit point for the mermaids, who swim from the ocean to the developed underground water system of the primitive continent and transport marine resources to land countries for commodity trade.

Then transport the land national materials back to the undersea kingdom.

Transportation in the groundwater system is not attacked as often as land business.

Although it is not as fast as Xianzhou transportation, it is still very popular because of the cheap transportation price.

Naturally, there are groundwater transfer stations established by sharks in the underground water system.

Shark Nanwu just went back to the transit station and told his family that he was going to spend the winter in Xia Yu.

A distance of about 400 miles back and forth, for the merman in the blink of an eye, the merman Nanwu even talked to his parents at home for a long time before coming out, otherwise he would be able to come back in the early morning and wake up Su Yan from freezing.

"I'll give you something to eat, can you warm up?" Shark Nanwu looked at Su Yan, who was squatting on the ground and rubbing his hands, and said embarrassedly.

It was the first time she had encountered the fox demon, and she didn't know the fox demon's habits, but when she saw Su Yan's behavior pattern like a human race before, she thought that he would also like his soft and glutinous insulation layer.

But I didn't think of putting on a big oolong.

Shark Nanwu was a little embarrassed, and wanted to ask Su Yan to eat snacks to get the little fox's forgiveness.

"I can't control my temperature......... I haven't reached the transformation period of the demon clan's standards, and my current human form is actually maintained by secret methods. ”

As he spoke, Shark Nanwu unlocked his secret method.
