"It's kind of interesting." Shi Xin couldn't help but be a little interested in Mu Heng in his heart.

If you want to help him break through the realm, it is not difficult for him, and it is intentional to use such a painful way, in addition to his dislike for Mu Heng, he also wants to try whether this person is a little prominent. If this kind of pain is unbearable, it is better to disperse and cultivate as soon as possible and live happily in the world for a lifetime, than to be killed by someone in this world of cultivation.

The cultivation of the first order of the Ten Directions Realm is not much different from that of mortals, this guy not only carried it, but also didn't scream, and he has some ability.

After these things, Shi Xin's perception of Mu Heng has also improved a little, and he has more expectations.

And Mu Heng, who had already sensed the golden aura, was looking inwardly at the white mist in the dantian.

"Is this the golden spiritual power transformed by the golden aura?"

The first step of cultivation has finally been achieved, the aura of the five attributes of gold, wood, water, fire and earth has been successfully perceived by oneself, and the next thing to test is the quality of the spiritual root of the five attributes, and select a relatively high-quality one as the foundation of one's own cultivation.

Luo Yunjin was not around, and the speed of absorbing spiritual energy from the two spiritual roots of metallic and earth attributes could not be measured by the timekeeping method, so he had to try other ways first.

The same results can be obtained by using statistical analysis.

First of all, Mu Heng still wanted to try the problem of the fusion of the five attributes of spiritual power first. On the basis of absorbing the spiritual power of full gold, Mu Heng successively absorbed and transformed the other four attributes of wood, water, fire, and earth.

No surprises. Mu Heng looked at the body with one-half more wood spiritual power, one-fourth of the water spiritual power, one-eighth of the fire spiritual power, and one-sixteenth of the earth spiritual power.

The spiritual power of the five colors of white, green, black, red, and yellow was mixed together, but it was not chaotic, and Mu Heng could still feel that the spiritual energy of each attribute was only coexisting, and it was not mixed.

The stock of the five attributes is so regular, and Mu Heng seems to have greater confidence in the conclusion that the quality of the five spiritual roots is the same.

With a hint of fantasy, Mu Heng began to measure the speed of aura absorption.

When absorbing the aura, you record it with the number of your heartbeats. Although the heartbeat error is not small, in the case of a large enough number of times, the average speed absorbed by each attribute is still relatively accurate, at least the advantages and disadvantages can be compared.

I remember that the absorption time of the three attributes that I had tested was almost three quarters of an hour, or forty-five minutes. Mu Heng selected one of the three that had been tested, conducted two experiments respectively, and took the average value as a reference for the remaining two attribute experiments.

Three quarters of an hour to absorb the aura of the full wood, corresponding to the time-consuming heartbeat of 3,200 beats.

Next, the properties of earth and gold were tested.

Shi Xin next to him had already felt that Mu Heng had successfully comprehended the golden aura, but then he saw that he kept absorbing the aura of several other attributes at once, and his heart, which had been silent for thousands of years, finally had a trace of excitement at this time.

"Although I know that you have five kinds of spiritual roots, I haven't seen you in the practice of cultivating five attributes like this for many, many years." Shi Xin couldn't stop sighing in his heart.

Lu Siqi's eyes never moved away from Mu Heng for a moment, and the halos of different colors that lingered around Mu Heng's body made her a little dazzled.

"I've heard Senior Brother talk about his situation, he has a spiritual root with five attributes. In order to pick out the spiritual root that is a little more prominent among these five attributes, he cultivated the five attributes at the same time, and now he has finally reached this step. Lu Siqi didn't know if Shi Xinming didn't understand, but he was still happy to tell it.

At the same time, there is another layer of meaning that I want to tell it, it's not that the senior brother doesn't want to cultivate, but the roots are too poor and can't be fast.

"Oh?" Shi Xin thought that Mu Heng's five attributes would continue to cultivate, but he didn't expect that he just wanted to choose one of them, and he was suddenly a little disappointed.

"How?" Seeing its strange tone, Lu Siqi thought it had something to say.

"Nothing." Shi Xin said perfunctorily, and then went to the side to look at the stars.

Lu Siqi didn't have the heart to appreciate the moonlight, and always paid attention to Mu Heng's state, worried that something would happen to him.

After a night of back and forth absorption and release, Mu Heng finally completed all the established test plans.

It's just that the test results are not satisfactory. The absorption rate of the two attributes of gold and earth is 3195 and 3202 heartbeats respectively, which is not much different from the test results that represent the wood attributes.

"Now it can be basically determined that the quality of our five attribute spirit roots is equal, and there is no good or bad difference, and in general, it is the worst spirit root and the lowest qualification." Mu Heng made a final summary according to the experimental results.

Although he didn't like it, Mu Heng had already guessed about this result, which was not bad news. The original itself has five attributes, which is already the worst, so why bother with the worse.

Almost, isn't there more room for improvement? Thinking of this, I couldn't help but chuckle, and then stretched out as a look forward to a new day. I still have important things to do today, so I hope I can get lucky.

The morning sun shines on the south side of the Shiquan Mountains, and the flowers and trees on the slopes begin to come alive to welcome the first rays of sunshine and start the day's work.

"Senior brother, are you awake?" When Lu Siqi heard Mu Heng's yawning voice, he recovered from his distraction, and when he stared at Mu Heng's eyes, he screamed.

"Well, junior brother has worked hard." Mu Heng knew that Lu Siqi and Shi Xin were next to him, and they were definitely not deserting, and they were definitely helping him protect the Fa.

Although it may not be disturbed, a piece of people's hearts still has to be received.

"It's not hard, congratulations to my brother for getting what he wanted." The corners of Lu Siqi's mouth were almost grinning to the root of his ears, and his delicate face was full of excitement.

"Senior brother, why do you look happier than me?" Mu Heng saw Lu Siqi's exaggerated smile, which was far happier than when she broke through herself.

"Ahh Haha, all happy, all happy. Lu Siqi was not easy to answer, so he casually laughed and dealt with it.

"Little sister, thank you." Mu Heng then walked to Shi Xin's side and thanked him very solemnly. Receiving favors from others, how can you not think about reciprocating, if you can help Shixin in the future, Mu Heng will definitely repay this favor.

"What little sister, I'm your aunt." Although Shi Xin had already accepted Mu Heng a little in his heart, he still didn't want to give him a good face.

"Poof" Lu Siqi couldn't help but laugh when he heard this, noticed Mu Heng's sweeping gaze, and covered his mouth with his hand, forcing him not to make a sound.

"If you are willing to be my aunt, I have no problem, after all, it is much older than me." Mu Heng didn't mind this very much.

According to the concept on the earth, such as Shixin, it should be included in the category of immortals, and he respectfully calls his elders, and he doesn't feel taken advantage of.

"You.." Shi Xin didn't expect Mu Heng to be so refreshed, and he was choked half to death.

"Forget it, you still call me Shixin."

"Well, thank you."

Seeing that Mu Heng was so sincere, Shi Xin lost his temper.

"Senior brother, Shixin, let's go." After the matter here, Mu Heng beckoned them to hurry. Although it was a day's delay here, it was a good harvest. Lu Siqi not only obtained the stone heart, but also broke through to the tenth order of the Ten Directions Realm.

Mu Heng himself has also reached the first step of cultivation, completed the test of the quality of the spiritual root, and the next step is to choose one of them and start to speed up his cultivation.

The road is long, and I will go up and down to seek. The goal is ambitious, but the road must be underfoot.

Shi Xinfei led the way in the front, Lu Siqi followed closely behind, and Mu Heng went up to the back of the hall with his tail.

"Boom. Boom.."

"Senior brother, what's the sound?" Approaching noon, there was a roar in his ears, and Lu Siqi, who was at the tip of his ear, caught these sounds and asked curiously.

"I think it should be the thunder on the Foggy Sky Mountain." Mu Heng also listened carefully to the characteristics of this sound, combined with the homework he had done before, like the sound of thunder.

"Are we almost at the top, then?" Lu Siqi said in surprise.

Lu Siqi took care of the situation of the Foggy Heavenly Mountain that Mu Heng knew along the way, and when he heard that it was thunder, he guessed that it was not far from the destination.

"I think so." Mu Heng's face also showed some joy, but he understood the danger on the top of the mountain, and Mu Heng admonished again: "Senior brother, from now on, be vigilant, danger may occur at any time." ”

"Okay, senior brother, you have to pay attention too."

"Also, when you get to the top of the mountain, don't point your fairy sword at the sky." Mu Heng saw the fairy sword in Lu Siqi's hand and reminded him in a targeted manner.

"Why is that?" Lu Siqi raised the fairy sword that Mu Heng gave her, and stared at Mu Heng in confusion.

"Metal objects are electrically conductive and can easily attract lightning." Mu Heng picked the simplest truth and told her.

"In this case, I'll pay attention, senior brother."

The last stretch of the road to the summit becomes steeper, and you really have to use your hands and feet to move slowly. Fortunately, the physical fitness is very comparable, and the strength on the arm to support your weight is also easy.

Climbing over a hill in front of him, Mu Heng suddenly felt that his eyes were bright, no longer bare rocks, but a fantasy world.

What catches the eye is a huge basin on the top of a huge mountain, and in the middle of the basin is a pool of cold water. Above the basin were thick clouds, with serpentine lightning piercing the sky.

"Boom. Rumble.. Boom.." One after another, the incessant thunder was like a roar from heaven, tearing everything on the earth.

"What a strange sight." Lu Siqi stood under the clouds, looking up at the flickering scene above.

He had never felt the roar of thunder and lightning so closely, and Mu Heng also had a new understanding of its cognition.

Looking up, the peaks next to it were covered with snow, but this highest mountain was only thundering and not raining, and there was no rain or snow at all.

Looking at the north side of the foothills, it is gloomy and cold, and the warmth of spring on the south side is in stark contrast.

This Shiquan Mountain Range is somewhat similar to the Qinling Mountains. The south side is affected by the warm and humid airflow from the southeast, and the temperature is higher and there is more rain. The north side is blocked by mountains, so the warm and humid air flow cannot reach the north, and there is less rain.

Conversely, the cold air in the north is also blocked by the mountain peaks, which cannot affect the climate in the south.

The air flow on the north and south sides of the mountain reaches the position of the mountain range, which is blocked, and the change of air pressure, the air near the mountain will be squeezed into the air, and meet at the position of the mountain peak, bringing strong convection and producing snowfall.

It stands to reason that the Wuyin Tianshan Mountain should also be like this, but the cold and warm air here converge into dark clouds on the top of the mountain, and it is strange that there is only thunder, but no rain or snow.
