Lu Chen is now a jade bone body, and he is becoming more and more proficient in the concealment of his own breath.

Even though Fang Yin was a big realm higher than Lu Chen, if he didn't know it, he still couldn't see that Lu Chen had stepped into the Heavenly Realm.

After making sure that Lu Chen had no flaws, Fang Yin put his mind at ease, "Wait for an hour or two to pass, and the old man will go out again." "Leaving the grotto hall immediately will make Caifeng suspicious.

"Will Caifeng and the others suddenly break in?" Lu Chen asked.

"Before coming in, the old man had already instructed that no one was allowed to enter the grotto hall without the old man's permission. Fang Yin responded.

Lu Chen nodded.

With a slight groan, he took out a vase more than a foot tall and covered in dark red runes from his storage bracelet.

"This is the Soul Purifying Bottle. Before Lu Chen could explain, Fang Yin had already recognized at a glance what the treasure bottle in Lu Chen's hand was.

Slightly stunned, Lu Chen was relieved. Fang Yin is a powerhouse in the Yuan Dan Realm, and he is also a formation master, he is well-informed, and it is normal to recognize the Soul Purifying Bottle at a glance.

"Please look at the contents of the bottle. Lu Chen handed the Soul Purifying Bottle to Fang Yin, and at the same time opened the Soul Purifying Bottle, so that Fang Yin could explore the contents of the bottle.

Fang Yin didn't think much about it, and the power of knowing the sea escaped into the soul purification bottle, only to see that there was a green five-story pagoda inside.

"This is ......" Fang Yin's eyes were surprised, and for a while he couldn't figure out what this green five-story pagoda was.

"The sinister secret place is really a cage to suppress a fierce demon. Lu Chen said slowly.

First, the reason why he had told Fang Yin earlier that he had reversed the matter of refining Zhengang was actually to test Fang Yin's attitude towards him. Now he was sure that Fang Yin really thought about him wholeheartedly and was a trustworthy person, so he would take out the Soul Purifying Bottle and let Fang Yin know.

Second, he has not been able to solve the secret of this green five-story pagoda, and the matter of the esoteric martial arts artistic conception can only be left undecided. Fang Yin is a powerhouse in the Yuan Dan Realm, and he is also a formation master, he is well-informed, and he may have some understanding of the green and shining pagoda left behind after the soul of the strong man was destroyed.

Hearing this, Fang Yin was even more surprised, knowing that Lu Chen had something to say next, Fang Yin did not interrupt Lu Chen's rhythm, and looked like he was listening.

After a pause, Lu Chen continued: "When I found that fierce demon, he had been wiped out by the Five Elements Formation in the Dangerous Secret Land, and only a wisp of soul remained. And the green and radiant five-story pagoda in this soul purification bottle was obtained after refining and destroying the soul of that fierce demon. ”

"Oh. A hint of surprise appeared in Fang Yin's pupils, and then he seemed to think of something, and let out a low voice, "This green pagoda is related to the artistic conception of the profound martial arts?"

Lu Chen bowed slightly, and informed Fang Yin of the truth he had learned, "The esoteric martial arts artistic conception is actually a means used by that fierce demon to escape from the dangerous and secret place. That fierce demon didn't know how to make the lake in the heavenly mist reveal the artistic conception of martial arts, and the purpose of the fierce demon was to attract others into the dangerous secret place. Those who enter the dangerous secret land will continue to explore, and sooner or later they will destroy the palace of the five elements, causing the treasure of the five elements to be born. The treasures of the five elements are born and gathered, and the central area for suppressing that fierce demon will be opened. When someone enters the central zone, the demon soul will take away the person who enters. ”

After hearing this, Fang Yin was amazed and looked at Lu Chen carefully.

Obviously, before this, only Lu Chen knew the truth of the matter.

And Lu Chen was able to know the truth of the matter, naturally because the fierce demons in the dangerous secret place wanted to take away Lu Chen.

"Little Brother Lu, if it weren't for the fact that the old man had been with you for a long time, he would definitely suspect at this moment that you had been taken away by that fierce demon soul. After all, the person who cultivated the knowledge of the sea in the Zhengang realm, you are really the first person to see in the old man's life, and it is difficult not to associate the knowledge of the sea with the soul of that fierce demon. Fang Yin shook his head and smiled.

Fang Yin had just secretly sensed that Lu Chen's soul aura was extremely pure, and it was the same as before.

The Lu Chen in front of him was naturally the Lu Chen he knew, not the person who was taken away by the demon soul.

In addition, Fang Yin already knew that there was a purple villain in Lu Chen's sea of knowledge, and that purple villain seemed to be a nemesis of the soul.

The reason why the demon in the dangerous secret place failed to take away is most likely because of the purple villain in Lu Chen's sea of knowledge.

Lu Chen smiled indifferently and didn't say anything.

Fang Yin glanced at Lu Chen again, secretly amazed in his heart. Through Xiao Leyou and Yao Xinyue, Fang Yin already knew that Lu Chen was not the only one who finally entered the central zone, but also young heroes from other parties. But the demon only stared at Lu Chen, which was enough to see Lu Chen's extraordinary. Not only that, the fierce demon wanted to take away Lu Chen, but the result was that Lu Chen's soul was refined and wiped out, which shows Lu Chen's strength.

After thinking about it, Fang Yin seemed to think of something again, and hurriedly said: "Why does the old man suddenly think that your real intention of secretly leaving Ice Peak City this time is really related to the artistic conception of the Esoteric Martial Dao. As for dealing with Yan Yu and the others, as well as dealing with those who covet your head and spirit stones, it's just a passing, or even just a reason for you to prevaricate Ice Peak City. ”

"Old Fang has a good eye. Lu Chen arched his hand.

"Good boy, good means! If you hadn't said these things, the old man would have been kept in the dark. Fang Yin not only did not get angry, but praised it from the bottom of his heart.

Immediately, Fang Yin's expression was solemn, and he concentrated on exploring the green and bright five-story pagoda in the soul purification bottle.

The esoteric martial arts artistic conception involves all parties, Lu Chen, Xiao Leyou, Yao Xinyue, all three of them are deeply involved. If this matter is not resolved as soon as possible, sooner or later the Shattered Sky Mountain Range will set off an even greater bloody storm. At that time, with the strength of other Fang Yin, he may not be able to protect the safety of Lu Chen, Xiao Leyou, and Yao Xinyue.

Fang Yin probed carefully, and gradually became an eyebrow in his heart. The green five-story pagoda was previously hidden in the soul of the demon, but now it is safe and sound in the soul purifying bottle. The five-story pagoda is a soul-like thing, but it is not affected by the soul purification formation engraved in the soul purification bottle, and it is related to the esoteric martial arts artistic conception......

Lu Chen was silent.

In front of the mountainside cave.

Lin Shu, Xiao Leyou, Yao Xinyue, and Caifeng, the four of them suspected that Lu Chen had failed to break through the Heavenly Realm, and none of them had the intention of cultivating any further.

They all stared at the entrance of the cave, expecting Fang Yin to appear and inform them of Lu Chen's safety.

At this moment, Lin Shu and the others did not dare to use their spiritual power to probe into the depths of the Xiang Cave Mansion, they were worried that the spiritual power they had escaped would affect Lu Chen.

They didn't dare to investigate, so they could only wait, and the four of them were anxious like ants on a hot pot.

Time flies.

In the main hall of the grotto, Fang Yin seemed to have thought of something, and a touch of surprise appeared in his eyes.

"If the old man's expectation is good, this green and shining five-story pagoda is really the martial arts inheritance of that fierce demon. Fang Yin said suddenly, breaking the long-standing calm in the grotto hall.

"Martial arts inheritance?" Lu Chen was stunned.

Fang Yin bowed his head lightly and explained to Lu Chen, "You have refined the soul of that fierce demon, but you have never found anything related to the esoteric martial arts artistic conception. But the esoteric martial arts artistic conception can't be fabricated out of thin air, otherwise it won't be able to deceive a powerhouse of the Yuan Dan Realm like the Three Cities City Lord of the Shattered Sky Mountain Range. Therefore, this green five-story pagoda must be related to the artistic conception of esoteric martial arts. ”

After a pause, Fang Yin continued, "You said earlier that the demon was trying to take you away and use your body to break out of the cage. And the act of giving up is extremely risky, and can even make the soul incomplete. The fierce demon must have known this, so he first stripped out his martial arts to form a pure martial arts inheritance. In this way, the act of giving up will not affect the martial arts inheritance. When the fierce demons succeed, they can use the martial arts inheritance to quickly cultivate all the way without bottlenecks, and recover to the peak realm in a very short time. If one layer is a martial arts realm inheritance, the first layer is the Qi Sea Realm, the second layer is the Zhengang Realm, the third layer is the Yuan Dan Realm, and the fourth and fifth layers are above the Yuan Dan!"

Lu Chen's eyes moved slightly, in this way, before the fierce demon fell, it was actually a martial arts powerhouse of two great realms stronger than Fang Yin.

"Since it's a martial arts inheritance, why can't you explore it at will?" he wondered.

"This is similar to the artistic conception of martial arts. Fang Yin patiently explained, "If there is a martial arts artistic conception appearing, not everyone can comprehend it. Being able to comprehend the artistic conception of martial arts is related to many factors. Talent and qualifications, personal understanding, realm exercises, combat skills, and even heart, temperament, and so on. In other words, a strong person needs to find a personal disciple, and whether the strong person will find a random one or choose carefully. ”

Lu Chen was stunned.

In short, neither Fang Yin nor he was recognized by the green five-story pagoda.

After determining what the green five-layer treasure was, he secretly rejoiced. Previously, if he had forcibly refined the pagoda in the earth fire despite the danger of the purple soul puppet being damaged, he was afraid that this martial arts inheritance would have been destroyed.

After groaning, Lu Chen made a decision in his heart, "Please ask Fang veteran Xiao Leyou, Yao Xinyue, and Lin Shu to summon the grotto hall one by one." ”

Fang Yin immediately understood what Lu Chen wanted.

"How can this be. You have a lot of relationship with Lin Shu, let Lin Shu try nothing to say, if he can get the recognition of the martial arts inheritance, everyone will be happy. But if You'er or Yue'er gets the approval of this martial arts lineage, you will lose a powerful martial arts lineage. Fang Yin immediately refused, his expression firm.

"I don't have this martial arts inheritance recognized, even if I hold it in my hands, it's just a waste. If Elder Fang could be recognized by the Martial Arts Inheritance, Lu would not mind giving the Martial Arts Inheritance to Elder Fang. For Xiao Leyou, Yao Xinyue, and Lin Shu, it is the same reason, as long as any of them can be recognized by the martial arts inheritance, I will give this martial arts inheritance. Lu Chen's mentality was indifferent, "And the matter of the esoteric martial arts artistic conception must be solved as soon as possible." ”

Lu Chen's last sentence moved Fang Yin.

"Okay, the old man will call them down. ”

With that, Fang Yin exuded a wave of sea awareness power.

Suddenly, Lin Shu came to the grotto hall.

Let Lin Shu come in first, it was deliberately done by Fang Yin. If Lin Shu could be recognized by the five-story pagoda, Xiao Leyou and Yao Xinyue would not need to try.

Seeing that Fang Yin first called Lin Shu, Lu Chen guessed Fang Yin's thoughts, and at this moment, Lin Shu had already come in first, so Lu Chen didn't say anything.

"How is it?" Lin Shu asked worriedly, looking at Lu Chen.

"The old man took action personally, and he was no longer in trouble. Fang Yin relieved Lu Chen, and then instructed Lin Shu, "Escape a wisp of spiritual power into this bottle." ”

Although Lin Shu didn't know why he wanted to do this, he didn't ask much, and directly escaped a wisp of spiritual power into the soul purification bottle.

Lu Chen and Fang Yin knew what was going on, and they were secretly looking forward to it.
