Li Yuan and the other eighteen people who had passed the second level of assessment followed the old man for a short walk, and then arrived at the cliff located in a secluded place in the Heavenly Master's Mansion.

"The small pool you see ahead is the destination of this time, the soul pool used to test the spiritual root. The old man said with his back to the crowd.

Everyone looked in the direction of the old man, and sure enough, they saw a small oval pool the size of a hot spring pool.

"Is this the Spiritual Pool?" Looking at the small pool in front of them, which was full of white gas and like a fairyland on earth, everyone exclaimed in unison.

"The water in this spiritual pool is relatively special, it is very sensitive to the attributes of the five elements, and it can also react to the spiritual roots with attributes. After the old man glanced at everyone, he slowly spoke.

"But before I test the Spiritual Root, I have some basic knowledge about the Spiritual Root to tell you. Seeing that everyone was aroused, the old man added, and then explained to everyone some common sense knowledge about the spiritual root that cultivators should know.

Soon, Li Yuan benefited a lot from the old man's explanation and learned some spiritual root knowledge.

First of all, the spiritual root is born by nature, almost impossible to create, it represents a person's affinity with the aura of heaven and earth, a person's cultivation qualifications have been determined by nature, even if the acquired can change the effect is not very great.

Generally speaking, the spiritual root is divided into five attributes of gold, wood, water, fire and earth, which is often referred to as the five elements of the spiritual root, in addition to the mutated spiritual root, that is, the spiritual root of two or three five elements mixed together and sublimated, such as the ice spiritual root of the water spirit root and the earth spirit root mutation, the gold spirit root and the fire spirit root mutation is called the innate favor of the thunder spirit root, the gold wood spirit root mutation of the wind spirit root, and even the dark spirit root, etc., these spirit roots are uniformly called "alien spirit roots".

And the quality of the spiritual root depends on the number of spiritual roots, most people's spiritual roots are a mixture of five or four attributes, although these people can also sense the aura of heaven and earth, but the effect of cultivation can be said to be miserable, basically can only cultivate the basic exercises to the third or fourth layer, that is to say, no matter how hard you try, you can only wander in the qi refining period for a lifetime, and there is no hope of crossing the foundation building period, so these five, or even four attributes of the spiritual roots are also called "pseudo spiritual roots", which means very poor spiritual roots.

In addition to the alien spirit root and the pseudo spirit root, there is also a kind of spirit root that only has two or three attributes, called the "true spirit root", and the cultivation speed of this true spirit root is much faster than the pseudo spirit root, and the comparison between the two is like the gap between the worst student in the class and the student who ranks in the middle class.

Finally, there is an excellent spiritual root that is respected as "Heavenly Spirit Root", this Heavenly Spirit Root is the name of a spiritual root with only a single attribute, because a person who has a Heavenly Spirit Root, no matter what kind of attribute, his cultivation speed is two to three times faster than that of an ordinary True Spirit Root, and when he cultivates to the peak of foundation building and breaks through the Jindan Period, there is no bottleneck at all, it can be said that there is no accident, as long as the time is up, he can be guaranteed to the Jindan Period, and the gap between the Heavenly Spirit Root and the True Spirit Root is like the ratio of the first student in the class to the middle-class student.

Of course, the appearance of the heavenly spiritual root is rare in a hundred years, or even a thousand years, if the person who was born with a spiritual root is one in ten thousand among ordinary people, then the heavenly spiritual root is one in ten thousand in the person with a spiritual root, or even one in a million, the probability is too low.

If you make a ranking according to the quality of the spiritual root, then the pseudo-spiritual root is lower than the true spiritual root, and the true spiritual root is much lower than the alien spiritual root, and the alien spiritual root is weaker than the heavenly spiritual root favored by the heavens.

Now that we know how to distinguish between good and bad spiritual roots, what is the specific embodiment of the good or bad spiritual roots? This must mention two key points, one is the speed of cultivation, and the other is the impact on spells.

For example, if a person's innate spiritual root qualification is only ten points, each additional spiritual root will be divided into a little qualification, for example, he is the water spiritual root in the heavenly spiritual root, then his water spiritual root qualification is ten, on the contrary, if the person's qualification is the water and soil spiritual root, then his qualification will be divided between these two spiritual roots, and the qualifications of each spiritual root range from one to nine.

Then the result is obvious, the cultivation speed of the heavenly spiritual root people only need to absorb a kind of spiritual energy with the same attributes as their own spiritual root and refine it to be able to improve their cultivation, and as the person in the true spiritual root, the water and soil spiritual root must absorb the aura of both water and earth attributes to be able to practice, and the cultivation speed will be much slower in comparison, not to mention the pseudo spiritual root, they must absorb four or five attributes of spiritual energy to cultivate.

In addition, in terms of the impact on spells, for example, if a person with a fire-type Heavenly Spirit Root cultivates fire-based spells, then his fire-based spells will be cultivated because they completely match the spirit root attributes, and the speed will reach the extreme, not to mention the power, there will be an attribute increase.

There are also some small knowledge about spiritual roots and spells, such as the person of Lei Linggen, who cultivates thunder spells, and his power is the strongest and most damaging of all the spells. The wind system is the fastest, and it is advantageous to escape or pursue. The earth system is the strongest defense, so people with soil spirit roots will mostly choose to cultivate some defensive spells.

The old man said so much about the basic knowledge of the spiritual root, and finally he mentioned one point, that is, although the birth of the spiritual root is difficult, but after the painstaking research of some well-intentioned people, it is found that this spiritual root is very easy to appear in people with the same bloodline inheritance.

For example, if one of the husband and wife has a spiritual root, then the child they have has a 1 in 4 chance that they will also have a spiritual root, and if both husband and wife have a spiritual root, the chance of a spiritual root in their offspring is higher.

This has led to the fact that in today's cultivation realm, there will be cultivators who go to the mundane realm to spread out their leaves, and when their descendants have descendants with spiritual roots, they are sent to cultivate, so there are many cultivation families, and there are more and more people with spiritual roots in the cultivation realm.

The concept of the Xiuzhen family is particularly prominent in the Huaxia Kingdom, so over the past few thousand years, there have been many famous Xiuzhen families with bloodline inheritance, such as the Wuhou Zhuge family who is proficient in the art of Qimen, the Ma family in the northwest, and the mysterious warlock family Zuo family, etc., are all Xiuzhen families that have been inherited for thousands of years, and they are extremely influential families in the entire Huaxia Kingdom.

"Okay, that's all I have to say about the spiritual root, and then I will cast a spell to close the ban and open the spiritual pool, which of you would like to be the first to come up and test the spiritual root?"

"I'll do it first. ”

Surprisingly, the first to walk out of the crowd was actually the middle-aged man who had outstanding performance in the assessment of crossing the river before, and was guessed by everyone to be a martial idiot.

"Well, that's good. The old man approved, then pinched his hands and hit the spirit pool, shouting: "Open." ”

Suddenly, Li Yuan's eyes narrowed, and the next moment he saw a burst of colorful ripples around the spiritual pool, as if an invisible door had been opened.

"What is this?" the crowd wondered.

The old man smiled and said: "This spiritual pool is extremely important for any sect, if there are people with bad intentions who deliberately destroy it, it will bring great trouble to the sect, so there is generally a ban outside the spiritual pool, which is used to prevent small problems, and the side of the spiritual pool of our Heavenly Master's Mansion has been laid a ban called the Thunder Pool Forbidden Law, as for the effect, you can take a look." ”

After saying that, the old man activated the prohibition again, and casually picked up a brick and threw it towards the spiritual pool.

There was a loud "thunderclap", and I saw that the brick that was about to fly into the spiritual pool was instantly split into powder by a thunderbolt as soon as it came into contact with the prohibition.

"Don't dare to take a step beyond the thunder pool, won't it be from here?" someone sighed.

"Alright, you can go in. The old man put away the prohibition again and said to the martial idiot.

Wu Idiot took a deep breath and strode into the spirit pool.
