Xiao Lao walked straight to the medicine jar, looked at it, and sure enough, as Qin He said, the spiritual liquid in the jar had become transparent.

"Strange, how did the spiritual liquid turn into clear water? My spiritual liquid is secretly made, in addition to the medicinal effect, it also contains a lot of spiritual power, this kid does not have a spiritual root in his body, how can he absorb the spiritual liquid?"

Seeing Xiao Lao's pensive look, Qin He didn't dare to disturb, just silently followed behind Xiao Lao. After a while, Xiao Lao suddenly turned around, grabbed Qin He's arm, and probed carefully.

"There are five basic spiritual roots in the world: gold, wood, water, fire, and earth, in addition to these, there are also some mutated spiritual roots, such as thunder spiritual roots, wind spiritual roots, etc., but even some powerful mutated spiritual roots, a mortal who cannot open the qi without spiritual roots, it is impossible to absorb all these spiritual liquids in an hour, is it a yin spiritual root or a yang spiritual root, no, if there is really a yin spiritual root or a yang spiritual root in the body, it can also be detected in the body, it is really strange, strange."

Xiao Lao said, slowly putting down Qin He's arm, pacing back and forth in thought. Qin He had never encountered this situation before. It stands to reason that these spiritual fluids are only used by him to stimulate Qin He's body and stimulate his potential, and a mortal without any foundation will not be able to completely absorb the spiritual energy in the spiritual fluid without a spiritual root.

In the Qinglong Continent, in addition to the basic spiritual roots, there are also some mutated spiritual roots, the so-called mutated spiritual roots, that is, the spiritual roots have undergone some kind of mutation in the process of growth, compared to the basic spiritual roots, the speed of the mutated spiritual roots to absorb the spiritual energy of heaven and earth is often faster, and the probability of breaking through the bottleneck of cultivation is often relatively large, but the probability of the appearance of the mutated spiritual roots is often relatively small, and once discovered, it will become the object of robbery by various sects.

In addition to the mutated spirit root, there are two extremely rare spirit roots in the Qinglong Continent, namely the Yin Spirit Root and the Yang Spirit Root, these two kinds of spirit roots are extremely rare, sometimes there has never been a single person for hundreds of years or even thousands of years, in the Qinglong Continent, the people who have these two kinds of spirit roots will not exceed the number of hands, and each of them is a famous existence, and every immortal cultivator with a Yin Spirit Root or Yang Spirit Root appears, which means the birth of a top powerhouse.

Just as Xiao Lao looked puzzled, Xiao Lao suddenly stopped, and there was a look of shock in his eyes.

"One yin and one yang, ethereal, the Tao is natural, hidden in the body! Is it the dual spiritual roots of yin and yang? Impossible, impossible, the spiritual roots of yin and yang have not appeared for hundreds of thousands of years, and the way of heaven will not allow this kind of spiritual root against the heavens to exist."

Qin He had never seen Xiao Lao look so out of shape, and listening to Xiao Lao's words, Qin He looked dazed.

"Elder Xiao, what you just said, I have never heard of it, it turns out that there are so many types of spiritual roots, and the yin and yang spiritual roots you just mentioned, is it a very powerful spiritual root?"

Listening to Qin He's question, Xiao Lao didn't answer immediately, but just said to him with an extremely excited and excited look:

"Qin He, you wait here for a while, and I'll come when I go."

Saying that, Xiao Lao didn't wait for Qin He to speak, then turned around and left, walking towards the Ming Medicine Pavilion Valley.

Seeing Xiao Lao leave inexplicably, Qin He didn't know what to do for a while, so he had to sit cross-legged on the ground and wait patiently.

After a while, Qin He saw the figure of Xiao Lao returning, and Xiao Su'er also followed behind Xiao Lao, both of them carrying a big bamboo basket behind their backs, and the bamboo basket seemed to be filled with medicinal herbs.

After Qin He saw the two people, he stood up from the ground and walked towards Xiao Lao and Xiao Su'er.

"Old Xiao, Senior Sister Xiao, you give me the bamboo basket and let me carry it."

Qin He said to the two with a smile, seeing Xiao Su'er, Qin He couldn't help but nod at her. Seeing Qin He greeting her, Xiao Su'er couldn't help but smile.

"It's not in the way, it's just some medicinal herbs in it, and it doesn't weigh much, so I can just carry it on my back. You can wait by the side, and I'll prepare a vat of spiritual liquid for you."

After Xiao Lao finished speaking, he and Xiao Su'er came to the previous medicine jar, took off the bamboo basket behind him, and Xiao Lao began to put medicinal herbs into the medicine jar.

"Blue Spirit Grass, June Incense, Golden Holy Crow ......".

As Xiao Lao continued to put the herbs in the bamboo basket into the medicine tank, the originally clear water in the medicine tank had begun to slowly turn yellow, and as time went by, the color of the water became deeper and darker, and in just half an hour, it had turned golden.

"Grandpa, Senior Brother Qin is just practicing his body, but the spiritual liquid configured by these herbs contains a large amount of spiritual energy, Senior Brother Qin does not have a spiritual root in his body, so he can't absorb it at all, so isn't it a bit of a waste?"

Looking at the golden spiritual liquid that had just been configured in the medicine tank, Xiao Su'er asked with some puzzlement.

"Susu, there are some things that can't be looked at with common sense, such as Qin He, maybe he is an alternative."

After Xiao Lao finished speaking, he let Qin He directly enter the medicine jar, and Xiao Su'er on the side listened to Xiao Lao's words, showing a look of understanding or not.

After hearing Xiao Lao's instructions, Qin He did not hesitate at all, and directly entered the medicine tank, unlike before, this time after Qin He entered the medicine tank, he did not feel any pain all over his body, except that his body felt a little hot, and he did not feel any other discomfort.

"It's strange, it's been more than an hour, why haven't you absorbed the aura contained in the spiritual liquid."

Seeing that the spiritual liquid in the medicine tank was not absorbed by Qin He like last time, Xiao Lao seemed to have a trace of loss in his heart.

"Grandpa, there are more than a hundred kinds of herbs in the medicine tank, and each of them is more than ten years old, such a number of herbs, coupled with your unique configuration method, the aura contained in it is quite a lot, not to mention that Senior Brother Qin did not open the Qi Mansion, even if it is me, if I want to completely absorb the aura in these spiritual liquids, it will take more than ten hours."

Seeing that Xiao Lao's face seemed to be a little lost, Xiao Su'er on the side couldn't help but comfort her grandfather. She didn't know what happened to her grandfather, how could she let Senior Brother Qin absorb these spiritual energy in the medicine tank.

"Alas, yes, maybe I'm too naïve, how could I be so confused as to let someone who doesn't have a spiritual root try to absorb the aura."

Xiao Lao sighed, looked at Qin He in the medicine jar and said in disappointment.

At this time, Qin He, who was immersed in the medicine tank, did not hear the conversation between Xiao Lao and Su Su at all, when he first entered the medicine tank, Qin He only felt a little hot in his body, but as time went by, Qin He only felt that his body was getting hotter and hotter, and he also had a sense of impatience and depression in his heart.

Qin He hurriedly stabilized his mind and tried to calm down his heart, because he believed that only by stabilizing his mind and quieting his heart could he last longer in the medicine tank.

After another quarter of an hour, Qin He's heart slowly calmed down, but the temperature of his body was getting higher and higher, as his body became hotter and hotter, Qin He's body had begun to turn red, especially on his face, beads of sweat the size of beans kept dripping from his face into the medicine jar, Qin He seemed to be a little unable to hold on.

However, just when Qin He was about to lose his bearing, there was a strange feeling from his dantian, just like last time, after the strange feeling came from his dantian, all the discomfort in his body seemed to start disappearing in an instant.

A cool feeling spread throughout his body from the dantian, Qin He only felt that his body was comfortable to the extreme, and then an extremely pure power began to fill his body, and Qin He's brain was hazy for a while, as if he had entered a state of chaos.

"Grandpa, look at Senior Brother Qin, he ...... He seems to be absorbing the aura in the medicine tank?".

Seeing that Qin He in the medicine jar seemed to be undergoing some kind of change, Xiao Su'er on the side showed an unbelievable expression.

Xiao Lao also noticed Qin He's changes, his eyes suddenly became larger, staring at Qin He tightly, Xiao Lao couldn't help but walk towards Qin He, close to the medicine tank, Xiao Lao found that the spiritual fluid in the medicine tank was slowly changing, the original golden spiritual liquid was slowly becoming lighter at a speed visible to the naked eye, and the spiritual energy in these spiritual liquids was pouring into Qin He's body at an extremely fast speed.

"Grandpa, how could Senior Brother Qin absorb the aura so quickly?"

Seeing that Qin He's speed of absorbing aura was so perverted, Xiao Su'er couldn't help but be stunned for a while.

"Yin Yang Spiritual Root! This is Yin Yang Spiritual Root!".

Xiao Lao said excitedly, and there was a look of awe in his expression.

"Grandpa, I know the Yin Spirit Root or the Yang Spirit Root, but the Yin and Yang Spirit Root, why have I never heard of you before?"

Seeing Xiao Lao so excited, Xiao Su'er smelled suspiciously, because she had never heard her grandfather say anything about the Yin Yang Spirit Root, but seeing her grandfather so excited, Xiao Su'er couldn't help but be full of strong curiosity about the Yin Yang Spirit Root.

"Susu, I haven't mentioned the yin and yang spiritual root to you before, that's because the yin and yang spiritual root has not appeared for tens of thousands of years, before I learned in an ancient book, there is a spiritual root in this world, above all the spiritual roots, if the ordinary spiritual root is the people, then this spiritual root is the emperor, this spiritual root is the yin and yang spiritual root, the so-called one yin and one yang is the Tao, and the yin and yang spiritual root is also called the Tao root. It is also known as the Tao of Nature, this kind of spiritual root is hidden in the human body, as if it is integrated into nature, and no one else can detect it except for oneself. Moreover, the cultivation speed of the Yin Yang Spiritual Root is extremely perverted, just the speed of absorbing the spiritual energy of heaven and earth is dozens of times that of ordinary spiritual roots, and it is said that the Yin and Yang Spiritual Roots can hide their own cultivation, as long as they are not deliberately revealed, even if the other party's cultivation is high, others will not be able to see through his cultivation, I thought that the Yin and Yang Spiritual Roots seen in the ancient books did not exist, but I didn't expect that there really were Yin and Yang Spiritual Roots in this world."
