Feeling the tremendous changes in the aura of heaven and earth in the surrounding environment, Yue Yinchen slowly opened his eyes after running the 'Ten Illusion God Emperor Technique' for another week. Seeing that there was a substantial and converging aura vortex in front of him, Yue Yinchen's heart was also jumping, and he didn't understand it yet, in fact, this aura vortex was tossed out by himself.

Seeing the two straw mats not far away, Ji Qing'er and Ji Xiaoyu also started to practice cross-legged at some point. Yue Yinchen smiled slightly and didn't bother them, and then her heartstrings moved, thinking that Ji Qing'er had said that the reason why the 'Sound Beast Technique' could not be cultivated was because of the loss of the aura of heaven and earth in the mortal world. But at the moment, isn't such a majestic aura exactly what the 'Sound Beast Technique' needs? Immediately, without hesitation, he took out the volume of the 'Sound Beast Technique' spirit recipe in the ring.

With the gradual deepening of the cultivation of the spiritual formula, Yue Yinchen only then knew why this 'Sound Beast Technique' could not be cultivated in the mortal world! It turned out that the key to practicing the 'Sound Beast Technique' was to use a large amount of heaven and earth aura to compress it, convert it into spiritual power, and condense a special mark called 'Yuan Shen Lock' in his own sea of divine consciousness, and after encountering his favorite demon beast, he used the 'Sound Beast Technique' to control it, and then called it ' Once the demon beast disobeys its master, the master can use the secret technique to detonate the 'Yuan Shen Lock', and then the demon beast can only end up with a soul scattered and never reborn.

Although this method seems to be quite cruel, it seems to be extremely unfair to the demon beast family. However, strength has always been respected in the cultivation realm, and monks and demon beasts have always been mortal enemies of each other since ancient times. Therefore, Yue Yinchen only sighed slightly in his heart, and then threw this idea out of the clouds, and began to try to use the aura of heaven and earth to transform the spiritual power and condense the mysterious 'Yuan Shen Lock'.

It's also strange to say, it can be seen from the 'Sound Beast Technique' that it seems that this sacrificial condensation of the 'Yuan Shen Lock' is quite complicated and easy to fail!

According to the method written on the spiritual formula, after Yue Yinchen ran the spiritual energy of heaven and earth into the skull and compressed it into spiritual power, it was to let it jump out of the sand and vein confinement with the trajectory of the spiritual technique, and followed another unknown supernatural path to his own divine consciousness. And in the meantime, what was unexpected was that the 'Heavenly Hatred' sword spirit that was flowing freely in the path of the veins and veins also separated into an extremely subtle purple light, closely following the spiritual power into Yue Yinchen's sea of divine consciousness!

Immediately afterwards, the spiritual power that had been condensed by the aura of heaven and earth just now was to entangle and rotate the purple light that followed layer by layer, and after about a stick of incense, it turned into another more slender and petite 'Heavenly Hatred' phantom, which hung quietly in the sea of Yue Yinchen's divine consciousness.

Feeling that this 'Heavenly Hatred' phantom should be the 'Yuan Shen Lock' contained in the 'Sound Beast Technique', and its current power is enough to imprison a third-order demon beast's Yuan Shen. Yue Yinchen was overjoyed, and slowly broke away from his eyelids that were faintly shaking because of excitement. Seeing that Ji Qing'er and Ji Xiaoyu's cultivation had not yet been completed, he turned the 'Sound Beast Technique' to the last page again, and checked the forging method of 'Beast Soul Evolution'.

As the eastern sky gradually turned white, the rich aura in the cave gradually dissipated, and the eyes of Ji Qing'er and Ji Xiaoyu also opened one after another.

Seeing that Yue Yinchen was still holding the 'Sound Beast Technique' in his hand and still bowing his head and thinking hard, Ji Qing'er stretched an extremely comfortable lazy waist, presented the graceful curve in front of his eyes and said, "Brother Yinchen, how well did you rest last night?"

Hearing this, Yue Yinchen looked up at the round and tight bulge on her chest. Slowly looked away and said: "Not bad! I don't know why, the aura in these 100,000 mountains is so thick that it sticks! With the majestic aura of heaven and earth last night, Yue Mou's practice of the 'Sound Beast Technique' was fortunate enough to condense a mark of the 'Yuan Shen Lock'. ”

"What?" Hearing Yue Yinchen say this, Ji Qing'er, who was originally gentle and graceful, delicate and charming, suddenly widened her eyes, raised her body, and said with a shocked face: "Brother Yinchen, last night should have been your first practice of the 'Sound Beast Technique', right? The Yuanshen Lock' will collapse invisibly, and after trying it several times, it is the same result, I don't know how many times Brother Yinchen used it to condense the 'Yuanshen Lock'?"

Hearing Ji Qing'er's question, Yue Yinchen touched her nose a little embarrassed and said, "Hmm~~!

As soon as these words came out, Ji Qing'er was already sluggish, and she looked at him in a daze, but she couldn't answer.

Seeing her like this, Yue Yinchen smiled and said, "Qing'er, in fact, the reason why my brother was able to condense the 'Yuan Shen Lock' mark at one time is because the other technique that my brother cultivated was quite miraculous, and it helped a lot when gathering spiritual power at the last moment! Otherwise, it wouldn't have been so smooth." However, the aura in these 100,000 mountains is so strong, there must be a few more days, and after you master the spiritual power, you will be able to easily condense the 'Yuan Shen Lock' imprint!"

Listening to Yue Yinchen's meaning, he didn't seem to know that the source of the rich aura last night was actually from himself. Ji Qing'er's beautiful eyes swirled, and she said with a smile: "Then it's okay, in the family trial of this 100,000 mountains in the future, Brother Yinchen will have to cultivate with Qing'er and Sister Xiaoyu every night!"

Yue Yinchen nodded, glanced at Ji Xiaoyu, who was standing on the side with a smiling face, and said: "It's not too early, let's go! Today we will go deeper into the 100,000 mountains again, it is best to encounter a powerful demon beast, and try the power of this 'Yuan Shen Lock'!"

Seeing that Yue Yinchen was already a little impatient, Ji Qing'er and Ji Xiaoyu looked at each other and smiled, and after nodding at him, they came out of the cave under his leadership and continued to march towards the depths of the 100,000 mountains!

————————

In the depths of the core of the 100,000 mountains, a towering giant tree that plunges straight into the sea of clouds and is surrounded by mist, and the dense and opaque branches and buds are intertwined into the top crown platform of the giant tree. Four strange figures haunted by the mist stood casually, quite tacitly silent, waiting for others to speak first!

"Hey, it's been time to stand for a stick of incense, don't you want to say something?" Seeing that the other three seemed to be very calm, and did not want to speak, a slightly old voice broke the deadlock.

As his words fell, not far from him, another graceful figure with a bumpy waist and long legs received a wisp of extremely soft voice: "Did that strange young man last night really come from the 'Sound Beast Technique'?"

Unexpectedly, the soft and charming woman had just stopped speaking, and the stout man standing opposite her snorted coldly: "Hmph! You haven't been manipulated by the 'Sound Beast Technique', do you still need to ask such an obvious question?"

"You!"

Seeing that the bewitching woman was about to sneer at this strong man's words, the elegant middle-aged man who had not yet spoken shook his sleeves and stopped: "Okay! That's all an old thing thousands of years ago, why does Brother Yuan need to mention it again and provoke the Stygian Feather girl? This time is not the same as in the past, and the strange young man who practiced the 'Sound Beast Technique' is not the same as the sky of the past, I and the other four of us join forces, are we still afraid of him?"

Seeing this elegant middle-aged man say this, his eyes are also shining. The strong man surnamed Yuan, who was stopped by him, laughed in a weird way: "Hehe, Brother Hanyuan, do you think that the kid who controls the 'Sound Beast Technique' is only the fifth realm of the Great Brahma Realm, and he can't pose a threat to us, right? But don't you forget, that 'Sound Beast Technique' is designed to attack the soul, and it has a lethal control ability over my demon beasts, and it is not that you can judge the strength or weakness by looking at the realm of the person who uses the trick!"
