In the fourth secret room, Xia Yin saw a scene completely different from other secret rooms.

In the secret room, there was no pillar of fire, but there were more than a hundred rabbits, pheasants, and even young wolves, all of which were scurrying around wildly.

The three young monks sat in the middle of the chamber, their eyes closed.

Xia Yin found that among the more than a hundred Yin Beasts, more than a dozen of them were different from other wild Yin Beasts, they looked very well-behaved, and they also posed in various postures strangely, some crouched, some with front paws like people with their hands folded, and some of them kept jumping rhythmically, like a dance.

"Cai Daoyou, it seems that these dozen or so Yin Beasts have been controlled by these three monks, right?"

Nanohiro smiled and nodded: " Yes, the spiritual secret technique they are cultivating is called Divine Mind Possession, which can integrate spiritual power into the sea of soul consciousness of these Yin Beasts and control their actions, of course, the cultivation of Divine Mind Possession, the most important thing is to use it in refining, this kind of spiritual secret technique can enable them to integrate spiritual power into the Horcrux rough, and have a deeper understanding of the Horcrux rough, according to the ancestor, if the Divine Mind Possession is cultivated to the extreme, and even be able to understand what the Horcrux rough is composed of, it can be called insightful, if it reaches this point, the refining tool will be foolproof, and there will never be defective products！”

Insight into what materials are made of......

Xia Yin muttered to himself with a shocked face.

This is indeed already in the realm of subtlety, controlling the essence, and it is already in the realm of returning to the source, which is equivalent to touching the edge of the law!

Cai Zhihong naturally understood what Xia Yin was thinking: "Hehe, if you want to cultivate the divine mind to the extreme, it is naturally difficult to reach the sky, and the ancestor himself is still far from this point, these words were left by the ancestors three thousand years ago in the classics, even the ancestors have not reached this point, this is just the ancestor's guess about the limit of this spiritual secret technique!"

Xia Yin nodded: "This Zhang naturally knows!"

However, deep down, Xia Yin had already included this spiritual secret technique in the compulsory category.

Not to mention the refining weapon, the mere fact that you can control the souls of others or beasts can be called rebellious!

The next moment, Cai Zhihong spoke: "These things that Cai took Zhang Daoyou to see are all secret skills that Daoyou must cultivate and master, and refining weapons is essential!"

After the two walked out of the secret room, Cai Zhihong took out two jade slips from the storage bag and handed them to Xia Yin: "This is the magic decision of the transformation soul and the divine mind possession of the spirit, as for the soul splitting technique, Zhang Daoyou obviously doesn't need to practice anymore, so master these two secret techniques first, and then let's consider the matter of refining the soul fire, the ancestor said, you must be given a very powerful flame, even if it is not the spiritual fire of heaven and earth, at least it must be close to this level!"

Xia Yin suddenly smiled mysteriously, and then snapped his fingers......

Shout!

A half-red, half-hundred-hundred-flame appeared in the air, turned into a firebird, and danced in the air.

"The matter of soul fire, you don't need to worry about it, Zhang Mou refined a wisp of Yuehua Jinyan by chance!"

"Oh my God...... This is, it turned out to be Yuehua Jinyan, Cai Mou has seen this kind of spiritual fire record in the classics, I can't imagine that I can see the real Yuehua Jinyan today, hey, no, how can Yuehua Jinyan be red?"

After the shock, Nanohiro was puzzled again

"Hehe, this is Yuehua Jinyan devouring a wisp of flame containing Vermilion Bird's bloodline, producing a mutation!" Xia Yin explained with a faint smile.

Cai Zhihong stared at Xia Yin in an instant, with a look of envy and jealousy.

"Zhang Daoyou, you...... You're in good luck!"

For the monks of the Land of Broken Yuan, being able to have a wisp of spiritual fire is simply a great blessing!

The two of them re-embarked on the flying boat and shot towards Xia Yin's residence at the foot of the mountain......

Suddenly, the communicator on Cai Zhihong's body sounded Gong Buer's voice: "Uncle Shi, Senior Zhang, who is guarding the Tibetan Scripture Pavilion, has sat down, and the ancestor asks you to go over and deal with the aftermath!"

Xia Yin couldn't help but look at Nanohiro in surprise.

"Cai Daoyou, the senior who guarded the Hidden Scripture Pavilion should be a demon from the Netherworld outside, right?"

Nanohiro nodded: "Yes, and it has a lot of origins!"

Immediately, Cai Zhihong's face showed a look of doubt: "Strange, how could this senior suddenly sit down?" According to the ancestor, even in this land of broken yuan, there is no demon temperature to nourish the body, but with the strength of the predecessor Zhang, he can still live for at least three hundred years!"

Xia Yin asked with some curiosity: "What is the origin of this senior Zhang?"

Cai Zhihong said: "Cai overheard the ancestor mention that this senior is the number one sect leader in the Netherworld, as for how he came to the land of Broken Yuan, Cai doesn't know!"

"The First Sect of the Netherworld!"

Xia Yin's heart was secretly shocked.

Sure enough, it's not small!

It's a pity that in this broken yuan land, no matter what identity this person is outside, how strong his strength is, he is of no use at all, and he can only become an unknown gatekeeper in the Soul Refining Valley......

Back at the residence, Xia Yin said to Cai Zhihong: "Trouble Cai Daoyou and Senior Gong to say that Zhang wants to take his apprentice back, so as not to worry about his sister at home!"

Cai Zhihong said with a smile: "The ancestor has long expected that Zhang Daoyou will have such an idea, and he has already instructed that Zhang Daoyou can go back at any time, just need to come back within three days!"

Xia Yin paused for a moment, and then understood.

The land of Broken Yuan itself is not very large, everything is under the control of Soul Refining Valley, and the old monster Gong De is obviously not afraid that he will fly away, but fortunately, he pretends to be more generous to eliminate the bad impression left by the last time he persecuted himself.

Xia Yin was naturally happy with such an ending and thanked him with a smile.

After Cai Zhihong left, Xia Yin walked to his room and found that Yin Yang Po had actually started to sleep again, and he had cultivated again in his dream, and black qi surrounded him like a poisonous snake, drilling in and out of the seven orifices......

Seeing this scene, Xia Yin's brows couldn't help frowning.

The sudden appearance of Yin Yang Po is really too weird!

Why did all of a sudden, such a phenomenon happen?

After a moment, Xia Yin shook his head.

This matter is so unbelievable that I can't think of any clue at all, so I can only put it aside for the time being......

Xia Yin didn't bother Yin Yang Po, but sat quietly on the side, watching the strange black qi on his apprentice's body wander between the seven orifices.

After a long time, all the black qi on Yin Yang Po's body finally penetrated into his body, and then he slowly opened his eyes.

"Hey, Master, you're back!"

The boy rolled over and got out of bed, apparently unaware of the strange things that had happened to him.

Xia Yin didn't break it, and said with a smile, "Let's go, let's go back and see your sister!"

"Ah......h

Yin Yang Po's face showed a touch of ecstasy, and there was a hint of disbelief.

"Master, didn't that old guy not allow us to take a step out of the Soul Refining Valley?"

Xia Yin glared at the unobstructed guy fiercely: "Pay attention when you speak, don't be disrespectful to the ancestor!"

Yin Yang Po's face showed a fierce color, glanced at the corners of his mouth, and sighed a little disapprovingly.

"Let's go!"

Xia Yin stood up and walked out the door.

Yin Yang Po was so excited that he kept rubbing his hands and followed closely behind the master.

Out of the door, Xia Yin directly sacrificed a bamboo leaf-shaped flying magic weapon, pulled Yin Yang to break the steps and stepped up, and then shot towards the highest mountain in front of him......

Shout!

The bamboo-leaf-shaped flying magic weapon slammed directly into the top of the mountain, and at the moment when Yin Yang broke and nervously grabbed Xia Yin's clothes, the flying magic weapon suddenly appeared in a gray world......

Without the sun and the flowers of different colors, the whole world was gray, and the strange trees on the mountains were winding, and the stamens of the trees could be seen everywhere in the canopy.

"Wow, compared to the world of Soul Refining Valley, this outside is simply too bleak and too monotonous!"

Yin Yang Po sighed heartily.

Xia Yin glanced at his apprentice with a smile, his lips moved a few times, but he swallowed the words back hard.

"Apprentice, if you have the opportunity, Master will definitely take you to see the real world!"

Xia Yin secretly said what he wanted to say in his heart.

The bamboo-leaf-shaped flying magic weapon flew rapidly towards the east, and soon came to the sky above the wasteland where the market was located.

Xia Yin glanced down, secretly feeling in his heart.

During this trip to the market, I didn't expect such a huge mutation, which allowed me to see the completely different world of Soul Refining Valley, as well as completely different cultivation methods and refining methods......

Flying all the way along the way they came, two hours later, the master and apprentice came to the sky above the three villages of the Heishui River.

Yin Yang Po pointed to the courtyard below, and was so excited that he almost jumped up: "Master, Master, let's get home, you see that is our yard!"

Xia Yin smiled and drove the flying magic weapon to slowly land in the courtyard.

"Sister, sister...... Master and I are back!"

Yin Yang Po shouted excitedly!

A figure rushed out of the room......

The moment she saw Yin Yang Po and Xia Yin, the girl on the opposite side rushed over with tears in her eyes, and actually hugged Xia Yin and Yin Yang Po, who had just put away the flying magic weapon.

"Woooooooooo......oo Master, Xiao Po, you're finally back, I thought ...... Woohoo......"

The girl was so excited that she couldn't even speak incoherently, buried her head between Xia Yin and Yin Yang Po, her shoulders twitched violently, and she cried so much that pear blossoms brought rain.

Yin and Yang broke his eyes, but there was no trace of tears, but the resentful and ruthless color had been completely replaced by gentleness and joy.

Xia Yin gently patted the girl's shoulder: "Let's go, let's go home and talk!"

The girl finally stopped crying and straightened up, her face showing a shy flush, obviously feeling that what she had just done was really inappropriate for a big girl.

"Sister, Master and I haven't been here these days, no one has bullied you, right?

Yin Yang Po continued to ask the question he was most worried about.

The girl shook her head slightly: "Now everyone knows that the master is an immortal master, where do you dare to bully me, I went out, and everyone bowed when they saw me, which was even more respectful than my own father!"

When she spoke, Yin Cuilian's face was also full of excitement and pride, obviously the girl was so respected for the first time in more than ten years.

This scene made Xia Yin smile, and then asked, "What about that Young Master Gong, did you come here to make trouble?"

The girl shook her head: "I didn't come, but the owner of the village came once, and he also sent a lot of food and daily necessities, so I can tell him at any time if I lack anything!"

Xia Yin was finally relieved.

Back in the house, the two sisters and brothers began to cook meals and were busy in the kitchen.

And Xia Yin also stood aside, watching the two sisters and brothers very skillfully and tacitly cut meat and cook rice.

When he arrived at home, Yin Yang Po seemed to be a different person, and her sister talked about the magical world she had seen in the past few days......

Later, the girl looked at Xia Yin countless times, although she didn't speak, but she was full of begging, and she looked pitiful.

Xia Yin knew that the girl also wanted to see the beautiful world depicted in her brother's mouth.

For a little girl who loves beauty, the beautiful scenery of Soul Refining Valley and the magical world are simply full of irresistible doubts!

After thinking for a while, Xia Yin said to Yin Cuilian with a smile: "If you want to go, Master will take you to play for two days, but you remember, it can only be two days, and Master can't be the master if you don't have one!"

Yes......

Yin Cuilian was so happy that she threw a handful of black leafy vegetables in her hand on the ground, jumped up high, and then threw herself into Xia Yin's arms without warning, and excitedly hugged Xia Yin's waist and shook it vigorously......

"Ahem...... It's only two days, and you won't be allowed to cheat then!"

Xia Yin admonished with some embarrassment, and then felt the girl's head in his arms constantly knocking on his chest, obviously nodding fiercely.

"Shy and shy, not shy, a big girl's family ......"

On the side, Yin Yang smiled and grinned on the side.

Yin Cuilian, who was in Xia Yin's arms, finally reacted, bounced up like a frightened rabbit, her face was already blushing to the base of her neck, and then she glared at her brother fiercely, and kicked Yin Yang on her ass with a "fierce" kick.

"Let you have more mouths, let your crow's mouth ......"

Yin Yang Po was kicked a few times, but he didn't care at all, and ran out of the kitchen with a smile.

The dim world, the dilapidated courtyard is full of laughter, full of endless warmth......

After the "family" had a hearty and happy dinner, the girl quickly washed the dishes and chopsticks, and then ran to Xia Yin's side, looking at Xia Yin with expectant eyes, wanting to speak several times, but she was a little embarrassed to speak, just rubbing the corners of her clothes desperately.

Xia Yin naturally knew that this little girl couldn't wait to go to the Soul Refining Valley, so he explained with a smile: "Hehe, now the Soul Refining Valley should be in the afternoon, and it will be night when we rush over, those people have to sleep at night, it is not very convenient to disturb, and we will set off in four hours, and it will be morning when we get there!"

"Oh, I know, Master!"

The girl replied with some regret, and the speed of the washing corner unconsciously accelerated, obviously she couldn't wait.

Xia Yin stood up: "Xiao Po, you talk to your sister, and the master goes out to do something!"

"Master, where are you going?" Yin Yang Po asked.

"Qingfeng Village!"

While speaking, Xia Yin had already walked to the door of the room.
