Imperial Physician Xue stood by the Moon Yin Lake and watched it for a while, then took out the booklet and brush from his arms, and after licking the pen, he recorded something on it.

Li Xuan was curious, jumped off Zhao Feng's shoulder, and walked to the feet of Imperial Physician Xue to take a look in the water together.

But the further you go into this pool, the darker it becomes, and you can see it clearly.

The black lotus seed that was thrown in by Imperial Physician Xue was long gone.

Li Xuan raised his head and looked at Imperial Physician Xue blankly, not knowing what he was remembering here.

But with this old man's temperament, there must be a reason for him.

Professionally, Imperial Physician Xue has never made any mistakes.

Imperial Physician Xue walked around the Moon Yin Pond, writing down two strokes from time to time, and finally stopped writing after a long time.

"Ah Xuan, it's your next turn."

Imperial Physician Xue smiled ill-intentioned at Li Xuan.

Cultivating Ziwu and Dilian is also very beneficial to Li Xuan, and he is also ready to contribute, and immediately asks:

"What do you need me to do?"

Imperial Physician Xue squatted down, leaned over to Li Xuan's side, and then said:

"It's not difficult, you can go down and help me get the lotus seeds back."

Li Xuan kept a straight face, staring at Imperial Doctor Xue silently, and scolded people with his eyes.

"Don't look at me like that, I'm all here to feed Meridian and Tilian."

"And I've heard you've already entered these two pools, so it shouldn't be difficult for you."

Imperial Physician Xue tricked Li Xuan into the water quickly.

Li Xuan looked at Imperial Physician Xue, and then at Zhao Feng, who was hanging high in the distance, and knew that he could only go down in person.

Anyway, he was also a little more curious about the Sun and Moon Yin and Yang Pool in front of him, so he happened to go down to find out.

"Can you just bring the lotus seeds up?"

Li Xuan checked with Imperial Doctor Xue before going into the water.

Imperial Physician Xue nodded again and again: "Yes, it's very simple." ”

"Of course, if you can, you can let the lotus seed sink as much as you can, observe it carefully, and wait until you can't hold on anymore, and then bring it back."

Hearing such a statement, it seems that Imperial Physician Xue did not simply throw the lotus seeds down to play, Li Xuan nodded in response to the matter, and then jumped into the Moon Yin Lake with a puff to find the small black lotus seed.

Seeing Li Xuan go into the water, Imperial Physician Xue stood up and stared carefully at the small shadow in the waterhole until it blended with the darkness of the waterhole and could no longer distinguish it.

At this time, Zhao Feng didn't know when he came to Imperial Doctor Xue's side, and the two looked seriously at the waterhole together.

"Imperial Doctor Xue, what is the success rate?"

"It's hard to say, you have to take a good look to say for sure."

The two of them were expressionless, patiently looking at the pitch-black water under their feet.

……

Soaking into the Moon Yin Lake again, Li Xuan no longer had the discomfort of last time, but was comfortable all over.

At this time, Li Xuan realized that the coldness of Yueyin Lake was not the same as the chill in Princess Ankang's body, and it had nothing to do with the cold, but the abundant extreme yin qi.

These are two completely different cold methods.

Li Xuan is also now able to clearly distinguish the difference between the two after he has the true qi of yin and yang.

In terms of the root of power, this is completely different, but in terms of performance, there is a similar coldness.

The Extreme Yin Qi in the Moon Yin Pool merged into Li Xuan's body, making his Yin and Yang True Qi become much more active, far faster than when he usually absorbed the Five Elements of Heaven and Earth.

"This Sun Moon Yin Yang Pool is a good place to cultivate Yin and Yang True Qi, so I have to come back often in the future."

Li Xuan's four paws slashed the water and swam towards the bottom of the pool.

The further down it goes, the stronger the extreme yin qi in the pool water becomes.

The Yin and Yang True Qi in Li Xuan's body also ran faster and faster.

"Compared to the power of the five elements that escape between heaven and earth, these pure extreme yin qi are better absorbed."

"When it comes to every month, the two days when the Sun Moon Yin and Yang Pond has the best effect, can you still cultivate faster?"

Although during this time, the cultivation progress of the Yin and Yang True Absolute Determination was not slow, but it would naturally be better if it could be icing on the cake.

Now, the Yin and Yang True Absolute Determination can have two or three points of progress every day, which is much faster than the progress of the two exercises in the Qi Sense Realm before.

The cultivation of Yin and Yang True Determination is much more worry-free than the previous exercises.

Since beating Li Xuan to practice this exercise, the Yin and Yang True Qi in his body has continuously absorbed the power of the five elements between heaven and earth, transforming it into Yin and Yang True Qi, making his strength slowly increase.

The Yin and Yang True Qi in his body now has increased a lot compared to when he first broke through.

Such a comfortable cultivation method made Li Xuan a little suspicious that the two beans he had eaten before had not yet been digested.

When Li Xuan concentrated on cultivating the Yin and Yang True Extreme, he could only slightly increase the speed of increasing the Yin and Yang True Qi, which was not too obvious.

Therefore, Li Xuan would run the exercises when he had nothing to do on weekdays, and then when he needed to do something else, he would let the exercises run passively, and he would not delay his cultivation at all.

Such a comfortable way of cultivation also made Li Xuan feel that the previous hardships were not in vain.

He endured such a slow progress in cultivation and didn't give up, which can be regarded as a point of hard work and a point of gain.

"The cultivation of Yin and Yang True Determination is not a problem, and it is a matter of course to reach the realm of perfection."

"Is it just that you can break through to the fifth grade so smoothly?"

Li Xuan felt a little skeptical about this.

After all, how can there be a truth that the more you cultivate, the better you can break through.

When Li Xuan was diving down and thinking wildly, his eyes suddenly lit up and he saw the lotus seeds that had been thrown down by Imperial Doctor Xue before.

The speed at which the lotus seed sank was far less than the speed at which Li Xuan dived, so he quickly caught up.

But Li Xuan was not in a hurry to go back, he still remembered what Imperial Doctor Xue had instructed him before, asking him to observe as much as possible.

The water in the Moon Yin Lake is not ordinary water, so the sinking speed of the lotus seeds seems to be a little slow.

Li Xuan swam around beside him, watching the changes in the lotus seeds.

The lotus seeds are pitch black, very similar to the black chess pieces that the three little ones are always playing with.

With the naked eye alone, the lotus seeds do not have any special changes, but they slowly sink in the water.

But if Li Xuan was engrossed, he could detect that the lotus seeds were absorbing the extreme yin qi imperceptibly.

"Oh, if you can absorb nutrients, you can cultivate it."

Li Xuan was overjoyed in his heart, and accompanied the lotus seed to sink silently.

As the Qi of Extreme Yin became stronger, the speed at which the lotus seeds were absorbed also changed.

From the weak at the beginning, it slowly became stronger, but then when it approached the bottom of the Moon Yin Pool, the speed slowed down again, until it finally hit the bottom, and the lotus seeds completely stopped absorbing the extreme yin qi in the pool.

"Hey, what's going on?"

"Is it because the Extreme Yin Qi around you is too strong?"

Li Xuan looked at the lotus seed who didn't react, no matter how he observed, he could no longer detect the movement of the lotus seed still absorbing the extreme yin qi.

He silently wrote down all these details, planning to let Imperial Doctor Xue study them by himself after he went up.

After Li Xuan put the lotus seeds into the Dihong Bone Ring, he was not in a hurry to leave.

Unlike the last time he came here, Li Xuan was very comfortable.

The Yin and Yang True Qi in his body was cheering, and the progress of the Yin and Yang True Absolute Determination was even faster to the naked eye.

Li Xuan stayed here for more than half a month, and estimated that the Yin and Yang True Absolute Decision would be complete.

"I'll have to talk to Zhao Feng later, and let him talk to Emperor Yongyuan."

"It's also good for them that I can improve my cultivation quickly."

Compared to the last time it was so cold that he almost fainted, Li Xuan only felt a burst of cold now.

But Li Xuan also understood that the pain of the last time greatly strengthened his physical body, and it was also the price of becoming stronger.

And this time, Li Xuan finally had the opportunity to take a good look at the bottom of the Moon Yin Pool.

The bottom of the Moon Moon Lake is made of unknown materials.

Li Xuan stood on it and could only feel a chill, and this chill came from the rich extreme yin qi.

He could clearly see that the ground under his feet was engraved with intricate lines.

If Li Xuan hadn't guessed wrong, this should have been some kind of formation.

It is also this formation that can allow the Moon Yin Pond to continuously absorb the Qi of the Extreme Yin.

It's just that whether the absorbed extreme yin qi has been stored or used for other purposes, Li Xuan can't tell.

But thinking that the water in the Moon Yin Lake was not getting more and more icy, but changing regularly once a month, Li Xuan guessed that this extreme yin qi was not retained in the Moon Yin Lake.

Otherwise, the Extreme Yin Qi in the Moon Yin Pool should be much stronger than it is now.

The bottom of the Moon Yin Lake was very dark, and with Li Xuan's eyesight, he could only see the range of less than three feet under his feet.

Li Xuan paced slowly under this, carefully examining the formation engraved here.

It's just that the complexity of this formation is far beyond his imagination, and after seeing not much, he feels dizzy for a while, and his brain is even throbbing for a while, as if there is a needle prick.

Li Xuan hurriedly closed his eyes, not daring to look more.

With his current cultivation, it is impossible for him to suddenly get sick, and there is a high probability that it is still a problem with this formation.

"Hmm, it hurts......"

It was the first time Li Xuan had encountered such a situation.

In the past, he had also wondered why these ordinary lines would produce such magical power after being built together.

But now it seems that there is indeed a force that supports the formation that he cannot understand now.

Li Xuan could only see that there was an extremely strong extreme yin qi in this formation, which was operating according to a certain law.

But more he didn't dare to look at it now.

The sudden headache was already a warning from his body, and Li Xuan didn't dare to continue to take risks.

"It seems that now is not the time to delve into this formation."

Li Xuan closed his eyes tightly, and the headache at this time made the operation of his turtle breath method much messier, which greatly reduced his diving time.

"No, you have to go up!"

Li Xuan no longer hesitated, and immediately swam towards it, but he was inevitably a little unwilling in his heart.

After floating for a distance, Li Xuan dared to open his eyes again.

At this time, his feet had been swallowed up by darkness again, and the details of that formation could no longer be seen.

"It seems that the study of this formation must be put on the agenda as soon as possible."

Previously, Li Xuan was pushed all the way by the practice, in addition to practicing his current exercises, he would record more other exercises when he had the opportunity, so that he could practice for Princess Ankang in the future.

But now that Li Xuan has cultivated into Yin and Yang True Qi, his strength has increased greatly, and he has some respite confidence.

He was originally very interested in other skills in this world, and he had also had the idea of learning formations, alchemy, and the like before.

Now it's time to put the formation on the agenda first.

"Next time I go to the Thousand Stars Pavilion, I have to find a book on this subject, and I have the opportunity to contact the talents in this area again."

Li Xuan silently made up his mind, the light above his head was getting closer and closer, and after a while, the water came out.

Seeing Li Xuan coming out wet, Zhao Feng immediately waved his hand and directly brought him to the shore with his strength.

Li Xuan used the yang attribute true qi in his body to bake, and the water stains on his body immediately evaporated, and the fur on his body immediately became dry and refreshing.

"Ah Xuan, what's wrong?"

"Have you found lotus seeds?"

Imperial Physician Xue couldn't wait to ask.

As soon as Li Xuan flicked his tail, the lotus seed in the Emperor Hong's bone ring suddenly flew towards Imperial Doctor Xue, who hurriedly grabbed it, but his feet slipped and he almost fell into the Moon Yin Pool, and Zhao Feng supported him with his strength.

"Ouch......"

"Uh, thank you, thank you, Mr. Zhao."

Imperial Physician Xue was pulled back to the shore in danger, and while he had palpitations, he didn't forget to thank Zhao Feng.

Zhao Feng smiled slightly and reminded: "Imperial Doctor Xue, pay attention to your feet." ”

After Imperial Physician Xue was pulled up, he concentrated on studying the lotus seeds in his hand, and took out the booklet and pen again for the second round of recording.

And Zhao Feng looked at Li Xuan and asked softly, "Ah Xuan, what's the discomfort?" ”

Zhao Feng saw that after Li Xuan came up, he had no energy.

"It's nothing, it's just a bit of a headache."

"I saw a formation below, and after looking at it for a while while while in curiosity, I started to have a headache."

Li Xuan wrote with his tail.

Seeing what Li Xuan wrote, Zhao Feng first glanced at Imperial Physician Xue, found that Imperial Physician Xue was taking notes seriously, looked at Li Xuan again, and then shook his head slightly.

Li Xuan saw Zhao Feng's hint and frowned, but he didn't continue to ask.

Obviously, Zhao Feng had something to say in front of Imperial Physician Xue.

It seems that no one else was allowed to enter and leave this place at will before, not only because Yuqing Pool was Emperor Yongyuan's private bath, but also because there should be other reasons.

Li Xuan looked back at the black and white pool, and also understood something.

This sun and moon yin and yang pool is not as simple as it seems.

Li Xuan buried this matter in his heart first, and then went to answer Imperial Doctor Xue's question.

Imperial Physician Xue mainly asked Li Xuan about his observations below, and then made a detailed record.

After the record was completed, Imperial Physician Xue also had a preliminary judgment.

"It seems that this meridian and Tilian's lotus seeds can survive here, but it's just ......"

As he spoke, Imperial Physician Xue came to the Riyan Lake on the other side, took a wooden bucket from the side, and took some water from the Riyan Pond.

Then, Imperial Physician Xue threw the black lotus seeds that Li Xuan had retrieved earlier into the wooden barrel.

The water in the Sun Flame Pond is about to reach its hottest time, and even now it is unusually hot.

Imperial Physician Xue was not afraid of scalding the lotus seeds that Li Xuan had finally fished up, so he threw them into the barrel.

The two of them and the cat immediately followed, and found that the black lotus seed, which had been quiet in the Moon Yin Lake before, was actually restless, and began to tremble violently in the barrel, as if it was about to explode at any time.

"Hey, hey, is this okay?"

Li Xuan patted Imperial Physician Xue with his tail and asked anxiously.

Imperial Physician Xue said calmly: "Let's look at it." ”

The black lotus seed trembled violently in the barrel for a while, and suddenly a gap cracked silently, and then it was much quieter.

Seeing this scene, Imperial Physician Xue exclaimed:

"The black lotus seed that contains the power of yin is actually going to be raised in the Riyan Pond!?"
