As soon as he entered the stone castle, Li Tianqi couldn't help but shiver, cold, too cold, the temperature in this stone castle was simply too low, so cold that Li Tianqi shivered.

At this time, a group of half-human and half-demon things appeared in the stone castle, some were human-headed and half-human, and some were wolf-headed and human...... These demons are all cultivators in the foundation building period, and they have not yet been able to completely transform into sincerity and benevolence.

Seeing the piano girl coming over, these half-human and half-demon immediately stopped and greeted respectfully: "See the young master!"

The piano girl nodded slightly: "Is my mother out of the customs?"

The demon with a head and a horse body hurriedly replied: "Back to the young master, the castle master has not yet left the customs." ”

"Haven't been out yet?" Qin Nu frowned and said to herself, "It's been a year of retreat, and it stands to reason that my mother should have been out of the customs for a long time...... Could it be that something has changed?" Thinking of this, the Qin Nu suddenly showed a trace of anxiety on her face, and raised her feet and walked towards the inside of the stone castle, this time, the Qin Nu did not take Li Tianqi with her, but handed Li Tianqi over to the Rémy Martin body to take care of.

Remy Martin didn't say a word, and directly locked Li Tianqi in the dungeon.

"Alas...... Seniors, please stay. Seeing that the body of Remy Martin was about to leave, Li Tianqi hurriedly shouted, the body of Remy Martin is the cultivation of the foundation building period, Li Tianqi naturally wants to call the senior, the cultivation realm is like this, as long as the cultivation is high, it is the senior.

Remy Martin stopped and asked impatiently, "What's the matter?"

"That, senior, can you change places for me, this dungeon is too cold......" Li Tianqi kept rubbing his hands as he spoke.

"I'm sorry, I can't be the master of this, you better stay here honestly. After saying that, Rémy Martin left the dungeon directly.

Li Tianqi shouted several times, but the body of Rémy Martin did not stop.

The dungeon is filled with a thick layer of ice, and the stone walls around it are covered with a thick layer of ice, and this dungeon is simply an ice cellar.

"Why is this place so cold? Li Tianqi found a relatively dry place, sat down cross-legged, put his hands on his knees, closed his eyes, and began to meditate and practice, at first Li Tianqi was so cold that his face turned blue and his whole body kept trembling, but as he meditated for a longer time, his face gradually became ruddy, and his body no longer trembled.

......

Inside a spacious stone hall.

The piano girl sat cross-legged on the ground, quietly staring at a stone door opposite, behind which was a secret room, where the piano girl's mother was in retreat.

The piano girl sat for seven days, and the piano girl was motionless for seven days, just quietly looking at the stone gate opposite.

As time passed, the harp girl's face was filled with worry and anxiety.

"Click......"

There was a sudden sound.

The piano girl's eyes lit up suddenly, staring nervously at the stone gate opposite, and there were words in her mouth, but her voice was too small to hear what she was saying.

"Click......"

The stone door on the opposite side slowly opened.

The piano girl's face was overjoyed, and she hurriedly stood up from the ground.

"Is the piano girl outside?" a woman's voice came from inside the stone door.

"It's a daughter. The piano girl hurriedly said, "Mother, why did it take you so long to get out of the customs?"

"Alas......" A heavy sigh came from the stone gate: "There was some accident this time......"

The piano girl was taken aback: "Accident? What kind of accident? Mother, are you okay?"

"I'm fine, except for some mistakes when cultivating. A middle-aged woman in a white dress slowly walked out of the stone gate, this woman's hair was high and coiled, her skin was fair, and her gestures revealed a noble temperament, this woman was the mother of the piano girl, and also the owner of this stone castle, named Quartz, was a dignified demon cultivator in the late Yuan Infant period, and she was also considered to have a certain reputation in the 100,000 mountains.

Seeing that her mother was safe and sound, the tense nerves of the qin girl were suddenly relaxed.

"Qinnu, nothing happened to the Stone Castle during my year of retreat, did it?" asked Quartz.

The Qin Nu shook her head: "No, everything is fine in Shibao, I went to visit my grandfather last month, and he said that he missed you, so you have time to see him." ”

"Counting the time, I haven't been to see my father for more than a year, which is really unfilial. Quartz had a look of shame on his face.

"Mother, you ...... You just said that something went wrong during the retreat, and it doesn't matter, right?" asked the harp girl with concern.

Quartz shook his head slightly: "It's nothing, it's just that when I was cultivating to the most critical juncture, I suddenly became unstable, which led to the abandonment of my previous efforts, this time I wanted to advance to the peak of the late Yuan Infant stage, and then I could try to break through the god transformation stage, but it's a pity...... At the last minute, it fell short. Speaking of this, Quartz's face showed a hint of loss, she has been in retreat several times, but it has not been successful, for hundreds of years, it has been stuck in the late Yuan Infant period, which makes Quartz feel very angry.

The qin girl reached out and held Quartz's arm and comforted: "Mother, don't be angry, if you don't work this time, just next time, you will succeed sooner or later." ”

Quartz nodded silently and did not speak.

"By the way, Mother, I captured a human cultivator the other day. The piano girl said suddenly.

Quartz was stunned for a moment, and then his face became gloomy: "Qin girl, I haven't told you many times, don't leave the 100,000 Mountains without permission, our demon clan and the human race have an agreement, we are not allowed to leave the 100,000 mountains without permission, and the human race is not allowed to enter the 100,000 mountains, no matter who breaks the contract, they will be killed!"

"Mother, don't be angry, my daughter and I haven't left the 100,000 mountains at all. The piano girl said hurriedly.

"You didn't leave the 100,000 Great Mountain, so how did you catch the human cultivator?" Quartz suddenly thought of something, and raised his eyebrows: "Is that human cultivator breaking into the 100,000 Great Mountain?"

The qin girl nodded: "Yes......" The qin girl immediately recounted the arrest of Li Tianqi.

After listening to the Qin Girl's story, Quartz's face suddenly softened: "I really didn't expect that the current human race is so bold that they dare to break into the 100,000 Mountains without permission!"

"I heard that human cultivator say that he was chased and killed by the enemy, and he had to hide in the 100,000 mountains. The piano girl explained.

Quartz waved his hand: "I don't care what the reason is for him, as long as he breaks into the 100,000 Mountains without permission, I will never spare him! Qin Nu, you immediately kill that human cultivator, and then hang his head at the entrance of the 100,000 Mountain, I want to warn those Terrans, if you dare to trespass into the 100,000 Mountains without permission, there will be absolutely no good end!"

"No!" Qin Nu shook her head again and again: "You must not kill that human cultivator!"

Quartz frowned: "Why can't you kill it?"

The Qin Girl smiled mysteriously: "Because that human cultivator is the Five Elements Miscellaneous Spirit Root. ”

"What!" Quartz's expression suddenly became excited, and he said in a trembling tone: "Qin girl...... You...... What you say is true? No...... Lie to me...... ......."

The Qin Nu smiled: "How dare my daughter lie to her mother, if it weren't for the fact that the human cultivator is the Five Elements Miscellaneous Spirit Root, I wouldn't have saved him." "If mortals want to cultivate immortals, there is an inevitable condition, that is, they must have a spiritual root, because only mortals with spiritual roots can sense the aura hidden in the air and absorb the spiritual energy to cultivate, so only with the spiritual root, human beings can cultivate, and the spiritual root is also differentiated, rough statistics, the spiritual root is divided into three kinds, the first is called "heavenly spiritual root", the so-called heavenly spiritual root refers to a single spiritual root, such as gold spiritual root, wood spiritual root, wind spiritual root, Lei Linggen, a single spiritual root, all belong to the heavenly spiritual root, the second is called "double spiritual root", as the name suggests, that is, a person has two caste spiritual roots, and a person with dual surnames spiritual roots, the speed of cultivation is a little worse than that of the heavenly spiritual root, but overall, the cultivation qualification is not bad, and the third type is called "miscellaneous spiritual root", and the miscellaneous spiritual root refers to a person who has more than three castes at the same time.

Spiritual root, it's not that the more surname spiritual roots you have, the better, but on the contrary, the more single spiritual root you have, the stronger your cultivation qualifications, for example, if you only have a fire spiritual root, then you can cultivate the fire surname law, and the speed of cultivation is several times that of others, if you have a thunder spirit root, then you can cultivate the thunder surname law, and the cultivation speed is also super fast.

The more people who have the surname of the spiritual root, the slower the cultivation speed will be, under normal circumstances, people with miscellaneous spiritual roots, the final cultivation will not be too high, of course, there are exceptions to everything, before there was a monk in the god transformation period of the human world, the magic power is much higher than other god period monks, at that time it was known as the "first person in the god transformation period", but for tens of thousands of years, there has only been such a monk in the god transformation period of the spirit root in the human world, it can be said that the probability of success is too low.

In fact, the miscellaneous spiritual roots are also divided into levels, people with three caste spiritual roots, the qualifications are average, people with four caste spiritual roots, then the qualifications are very poor, if you have five caste spiritual roots at the same time, then your qualifications are simply poor (but people with five caste spiritual roots are still rare, after all, it is difficult to have five caste spiritual roots at the same time, it is estimated that among millions of people, there may be a person with five caste spiritual roots. ）

I want to say here that in fact, the spiritual root is divided into five kinds: metal, wood, water, fire, and earth, and everyone usually calls it the "Five Elements Spiritual Root", as for what wind spirit root, thunder spirit root, etc., all belong to the mutated spirit root, in fact, strictly speaking, the wind spirit root and the thunder spirit root This kind of mutated spirit root still belongs to the scope of the five elements spirit root.
