Acting separately from Luo Yunjin, Mu Heng came to the Daozang Hall to inquire about the information related to the Taiyin True Water and the methods to obtain it.

It turns out that the so-called Taiyin True Water is the water of the origin produced when heaven and earth are first born.

"I said how difficult to obtain, this water should have been only available when heaven and earth were first born, and now if you want it, it is actually very difficult, not only luck, but also strength." Mu Heng looked at the record on the talisman and muttered to himself.

Since Mu Heng reached the first order of the Ten Directions Realm, he has been able to use spiritual power to decipher the content of the talisman, not only limited to paper books.

However, regarding the generation of Taiyin True Water, Mu Heng rummaged through the classics of the Daozang Palace, but did not find a suitable way.

"Hey, I can only try it myself, I don't know the birth method of Taiyin True Water, I can only try my luck." Mu Heng thought weakly, he didn't understand the principle of generation, and he couldn't even judge whether it was Taiyin True Water, so he could only count on Luo Yunjin.

Thinking of Ye Qingyin's troubled mood about this, Mu Heng also felt depressed in his heart, lamenting that he was weak and couldn't share her worries.

"I hope there will be a breakthrough over there." Mu Heng sorted out all the information he consulted and put it back in his place, greeted the palace keeper and returned to his bamboo building.

After dinner, Mu Heng prepared for the next trip. The difficulty of obtaining Taiyin True Water may be far beyond your imagination, and you must make more preparations.

To ensure a smooth trip, there are at least a few aspects to prepare:

First of all, the most basic thing is one's own self-cultivation. Because of the blessing in disguise, I realized the fire aura, and I must complete the test of the fire attribute spirit root before leaving, so that I can have more strength and more insurance.

Secondly, carry-on items. Daily necessities are indispensable, such as bamboo boxes, kettles, umbrellas, etc., which are related to the durability of the trip.

Finally, this time you can't just bring a bamboo cane, it's too inappropriate to use it as a weapon. Gotta find a way to get a sword, a knife or something.

Just do it. Mu Heng sat down cross-legged, channeled the fire spiritual power in the dantian to his fingertips, and as if by magic, a pinch of flames burst out.

"Ignition in the air." Mu Heng's fingers lightly squeezed out the aura on his fingertips. The flames were pushed and rushed to a pile of dead grass not far away.

With a faint sound, the withered grass burst into flames. Seeing this, Mu Heng couldn't help but sigh: "It's different to have aura, this ignition is like an explosion, and the fire grows quickly." ”

In the realm of the first order of the Ten Directions Realm, after absorbing spiritual energy and transforming it into spiritual power, the greatest benefit is to wash one's body, cut the marrow of the I Ching, remove toxins and impurities, and make one's body healthier and conducive to cultivation.

In addition, Mu Heng can only achieve a simple release of spiritual power, which is like an experiment that releases a stream of water, grows a small tree, and automatically ignites a fire.

Therefore, to sum up, in addition to being in better health, I still have almost no ability to fight.

"This kind of cultivation, breaking into the world of cultivation, is really not fast enough." Mu Heng kept shaking his head, if it was not necessary, he really didn't want to go down the mountain, it was too dangerous to go down the mountain.

-------------------------------------

"Senior sister, have you ever found out the news, how to get the Taiyin True Water?" The next day, Mu Heng and Luo Yunjin made an appointment in the Daozang Palace, plotting to find the Taiyin True Water.

"I don't have much information, I just know that Senior Sister found it in the Foggy Heavenly Mountain." Luo Yun spread his hands and said helplessly.

"Foggy Heavenly Mountain? I heard Yang Lan mention it, what kind of place is it? Mu Heng asked again.

"I don't know very well, I just heard my sister say that it is a place of thunder and lightning, and it is very dangerous." Luo Yunjin remembered that when Ye Qingyin mentioned these four words, the fear on his face made Luo Yunjin hesitate a little about this trip.

"Oh?" When Mu Heng heard this, his brows tightened, and what made Ye Qingyin feel dangerous was definitely a life of death for him and Luo Yunjin.

"Senior brother, what should we do now, are you still going to Wuyin Tianshan?" Although Luo Yunjin really wanted to help his senior sister, if he was looking for this Taiyin True Water far beyond his ability, he also understood that it was not worth the risk.

"Always try, even if you don't get it in the end, don't regret it." Although Mu Heng couldn't feel the actual danger yet, it didn't prevent him from using Ye Qingyin as a reference.

Make up your mind to check it out and try it if you have the chance. There's really no way to forget it, it's not advisable to give up your life in vain.

Luo Yunjin heard Mu Heng say this, and his heart seemed to become firm. However, another emotion rose in his heart: What is the relationship between the senior brother and the senior sister, so that the senior brother can take such a risk for the sake of the senior sister?

Curious eyes stared at Mu Heng, wanting to see something on his face.

It's just that Mu Heng didn't understand the meaning in Luo Yunjin's eyes, and he was still thinking about the next plan in his mind.

"Senior sister, when I make some preparations, let's go down the mountain to the Wuyin Tianshan Mountain." Mu Heng determined the general plan, and told Luo Yunjin in time.

"Oh, good brother." Luo Yunjin readily agreed. Returning to the matter of Taiyin Zhenshui, Luo Yunjin suddenly found that some of the things that Senior Brother had done so far seemed to be beyond his ability.

There are some things that even she can't do by herself, but Mu Heng has done it. Could it be that this search for the true water of Taiyin can also be done by him?

The speculation in his heart was quickly pinched out by Luo Yunjin. Although I have indeed seen the excellence of my senior brother, this time it was too difficult for the senior sisters to complete.

"Senior sister, now you have time, if you have time, accompany me to Mending Heaven Pavilion, I want to test the quality of my fire attribute spirit root." Mu Heng plans to complete the test of the spiritual root today, and by the way, ask if he can find a weapon.

"Senior brother who is free, let's go now." Luo Yunjin pulled Mu Heng and went out.

"Senior sister, if I want to get a sword or a knife, is there any way to do it?" On the way, Mu Heng consulted about weapons, thinking that Luo Yunjin should be familiar with this.

"Huh? Senior brother, what do you want weapons for? Luo Yunjin was a little strange when he heard this, and asked rhetorically.

"Next, let's go to the Fog Hidden Heavenly Mountain, and it will be safer to defend ourselves with weapons." Mu Heng explained.

"That's it, it's not difficult, just find Senior Sister Xingyin." Luo Yunjin thought for a moment and said.

-------------------------------------

"Senior sister, let's get started." The two of them directly found Xingyin and borrowed her cultivation place to test the fire attribute spirit root.

"Hmm."

Mu Heng released all the spiritual power in his body, said hello to Luo Yunjin, and activated the absorption of fire aura.

With the entry of the fire attribute aura into the body, a feeling that was warm at first and gradually became hot and hot constantly impacted Mu Heng's body: This fire aura is really irritable.

Unlike water aura and wood aura, the unique nature of fire aura made Mu Heng feel that it was difficult to control fire aura.

Looking at the spiritual power at the dantian, the sunset-colored mist filled the entire space, and it was like the brilliance of the glow, which was beautiful.

Feeling that there was no longer a trace of fire aura in his body, Mu Heng opened his eyes and signaled that Luo Yunjin could pinch his watch.

"Senior brother, it's also three quarters of an hour." Luo Yunjin reported the same time again.

"Sure enough, as I guessed, there is almost no difference in the quality of my five attribute spirit roots." Mu Heng shook his head slightly, what was expected.

"Senior sister, try a few more times." Although he was basically sure of the test results, Mu Heng habitually sought stability, so he tried again according to the previous statistical method.

"Okay, brother." Luo Yunjin said briskly.

Then Mu Heng repeatedly released the fire spiritual power, and then absorbed the fire spiritual energy, constantly transforming in the body. Luo Yunjin next to him also kept pinching his watch, and according to Mu Heng's instructions, he reported the time.

"It's three quarters of an hour." The last timer, Luo Yunjin said.

"That's it, let's try the influence between attributes again." Since the last time he absorbed the water aura and wood aura, Mu Heng had some strange thoughts in his heart, and he wanted to try to increase the fire aura again, would there be any new changes.

"No problem, brother." Luo Yunjin actively cooperated with Mu Heng.

Luo Yunjin, who was standing on the side, was no longer surprised that Mu Heng had made various attempts at low-level cultivation now, his qualifications were too low, so he could only try all kinds of methods, but he didn't feel bored when he accompanied his senior brother to cultivate every day.

"Why do I find it interesting to accompany my senior brother to cultivate, but I feel bored when I cultivate by myself." Luo Yunjin didn't know when he thought of this, and he was also very surprised in his heart.

shook his head, put aside his random thoughts, and continued to cooperate with Mu Heng to do experiments.

Using the "control variable method" often used in physics, Mu Heng wanted to first conduct a compatibility test of the two properties.

The first is to absorb the water aura on the basis of the abundance of fire spiritual power.

The second is to absorb the wood aura on the basis of the abundance of fire spiritual power.

At the beginning, absorbing water spiritual power on the basis of wood spiritual power, the total amount that could be absorbed was half of the former, and the efficiency was also half.

Now on the basis of testing the fire spiritual power, absorb the wood spiritual energy and water spiritual energy respectively, and the effect is almost the same as before, and the total amount and efficiency are similar.

"It seems that the two attributes are compatible, and the second attribute can only be filled in half, which is twice as efficient." Mu Heng summarized the test results in his heart.

The next step is to test the compatibility of the three attributes.

First of all, it is based on the spiritual power of water, and then absorbs the two spiritual energas of fire and wood in turn. The second and third steps are to absorb the aura of the other two attributes based on the wood and fire aura respectively.

It took half a day for Mu Heng to complete the test of compatibility with the three attributes.

The total amount absorbed by the third attribute is half of the second attribute, in short, the absorption of the first attribute, if the total amount is one, then the total amount that the second attribute can absorb is one, and the total amount that can be absorbed by the third attribute is one-quarter.

It is a simple proportional series, and the common ratio is one tenth.

In terms of efficiency, the absorption efficiency of the third attribute is half that of the second attribute, that is, a quarter of the efficiency of the first attribute.

The efficiency is also a simple proportional series, and the common ratio is also one-half.

"What a coincidence!" The results made Mu Heng a little surprised. However, in his previous life, he was used to all kinds of coincidences in mathematics, and he didn't care too much.
