"By the way, you just said that this ancient secret is opened every one million years. I don't know when it will be opened next time?" Lu Chen asked.

"My son, if you count it carefully, in another ten years, Ran Gu's Secret Store will open again." Luqiu glanced at Lu Chen and continued,'However, to enter Ran Gu's Secret Store, you need Ran Gu's portrait. . ’

After hearing this, Lu Chen remembered the portrait in his hand. Isn't the person painted on it called Ran Gu? With a move in his heart, he asked: "Rangu portrait, what is that?"

"The son, this portrait of Rangu, to put it simply, is a portrait of the Demon Emperor Rangu, with his essence left on it. Only with this portrait can he enter the secret store of Rangu. However, at the beginning, Rangu After the death of the Devil Emperor, only 49 portraits were left, and they are now in the hands of the big powers, and ordinary people want to get them, and there is no chance at all." Luqiu said.

"But this painting?"

Lu Chen listened, but flipped his palm, took out the portrait of Rangu, and handed it to Luqiu.

"This is... the portrait of Ran Gu?" Luqiu took it in doubt, opened it and saw the portrait of Ran Gu above, suddenly lost his voice, and said to Lu Chen in shock,'Master, this is the portrait of Ran Gu, you How did you get it? ’

"I found this portrait of Ran Gu from the storage ring of the Emperor Tibetan Devil." Lu Chen said.

"So that's the case." Luqiu nodded, and then said excitedly,'My son, with this portrait of Ran Gu, ten years later, when the Ran Gu's Vault is opened, you will be able to enter the Vault and obtain Ran Gu. The devil emperor’s inheritance, even if he does not get his inheritance, you can still get the various treasures in it. You must know that in the secret store, there are a number of ancient methods, emperor soldiers, top potions, and treasures of heaven and earth. Endless. ’

Having said that, he glanced at Lu Chen and continued: "Moreover, I heard other people say that in the ancient secret store, there is still an understanding of the Devil Emperor's Tribulation of Zhenbo every Tribulation. There are incredible benefits. Therefore, many of the Devil Emperors who have obtained the portrait of Ran Gu will enter the secret storage. If you get these things, the son will have a lot of benefits for you to enter the Devil Emperor in the future."

"If this is the case, the son will wait ten years to go and see in this ancient secret." Lu Chen said slightly, he wanted to leave the demon world at this point, but when he heard Luqiu's words, his heart was moved. .

After all, it is too difficult to step into the Divine Venerable Realm to perform. If you can survive the Divine Emperor Tribulation a few times, it is also a great blessing. After all, the difficulty of crossing the Divine Emperor Tribulation is unimaginable.

"Well, you go back first, my son will continue to practice." Lu Chen waved his hand.

"The old man retire." Luqiu bowed back.

"Rangu's Secret Treasure?" Lu Chen said a few words, his eyes flashed. There are so many treasures in this Rangu's Secret Treasure, so it is necessary for him to go there.

However, Luqiu said that even the Devil Emperor would enter the secret store, so the danger in this ancient secret store is definitely not less, and he needs to make some preparations.

Best to be able to break through the Devil's Mirror!

In this way, he will enter the ancient secret store and gain the grasp of treasures, which will be greater.

As for the inheritance of Demon Emperor Rangu, Lu Chen did not hold much hope. Since ancient times, no one has been able to obtain his inheritance, and the chances of obtaining it by himself are probably not great.

Then, the goal of this trip is mainly Demon Emperor Ran Gu's perception of breaking through the Demon Emperor Realm and crossing the Demon Emperor's Tribulation.

Then, Lu Chen began to prepare for his trip to the ancient secrets ten years later.

...

In a dark space in the Demon Realm, dark power swept through and flowed endlessly. There was also the essence of demonic energy and magic power, which gathered together like mountains and mountains, forming a terrifying dark shadow.

And right there, a young man sat cross-legged.

He was born in a jade tree facing the wind, unrestrained and unrestrained, with long, pitch-black hair flying, braving the black light, exuding the power of darkness, and it was extremely terrifying.

If Lu Chen were here, he would definitely be able to recognize him, he was Bei Ming who had appeared in the God Realm and had handed him once.

"Om——!"

He concentrated his attention and was silent in his cultivation, his hands kept pinching out the seal, the magic power was lingering, the dark power was boiling, and a black shadow condensed above his head, majestic and solemn.

Suddenly, a strong aura of strength radiated from him, rushing straight into the dark sky above, banging in all directions.

"Hahaha, Demon King Realm, I finally broke through the Demon King Mirror."

At this moment, Bei Ming opened his eyes, and the dim light in his pupils flickered, full of joy, and laughed, with endless joy.

"Huh, I step into the Demon King's Mirror now, and my strength has increased more than tenfold. That Lu Chen is definitely not my opponent. Unfortunately, Ran Gu's Secret Vault will be opened soon, otherwise I really want to find him Lu Chen, and then fight him. "Bei Ming grabbed the magic power of his whole body, his eyes were faint, and he let out a cold snort before losing to Lu Chen. He thought it was the shame of his life that he would definitely wash it back. However, when Ran Gu's Secret Vault was opened, he absolutely took this beforehand. Let it go.

...

In a lifeless space, there was a young man sitting cross-legged in his thirties. He had long gray hair, his eyes flashed black, and his lips were as thin as paper, giving people a mean feeling.

"Sky Burial Demon Skill, get up!"

Suddenly, while remaining silent, he let out a scream, and a terrifying death force swept out, accompanied by countless gray lights, with his hands, a series of magic talisman flew out, fused with those death forces, and turned into a strange space. , There are countless tombs, as well as all kinds of dead matter, dead creatures, there is no difference from hell.

As soon as this space emerged, the four directions were angry and extinct, as if they had fallen into death, everything in the world seemed to be buried, and the world would be destroyed.

"Devil Lingzi, have worked hard for thousands of years. You finally completed this Heaven Burial Demon Art at the beginning. Very good, you did not disappoint your teacher." At this moment, a voice suddenly came from an emptiness and wondering where it came from. .

"master."

The young man called Demon Lingzi immediately stood up and replied respectfully: "If a disciple can cultivate Heaven Burial Demon Art, it is the master's guidance, and the disciple dare not greedy gong."

Because his master is the Taishang Demon Venerable one of the five demon world!

"Devil Lingzi, this Heaven Burial Demon Art is the supreme magic technique created by the Ancient Burial Heaven Demon Emperor. Although he is not as good as the Nine Tribulations Demon Emperor Rangu, he is also a Seven Tribulations Demon Emperor. Gong, even the Devil Emperor of the Eight Tribulations, is not his opponent. Today, you have successfully cultivated this skill. I hope you don’t fall into his prestige. This time you enter the Secret Store of Rangu, as a teacher, I also hope that you can get as much as possible. Inheritance." Taishang Demon Venerable said, he did not show up, but his voice was omnipresent, as if he could penetrate nothingness, see through everything, and hit the devil's mind directly.

"Master, rest assured, the disciple will definitely go all out this time to get the inheritance of Emperor Rangu." Mo Lingzi said hurriedly.

"Well, taking advantage of the ten years left in Ran Gu's secret store, you don't want to go out, just stay here and practice." Taishang Demon Venerable said.

"Yes!"

Mo Lingzi nodded and continued to practice.

And Taishang Demon Venerable didn't say much, and didn't show up, no one knew where he was.

...

Dragon Blood City!

This city is in the Devil Realm, and it is no worse than the Sky Swallowing Devil City, because its creator is the Blood Kun Devil Emperor.

According to legend, the Devil Emperor Xuekun obtained a corpse of an ancient dragon, and he repaired it into a body as powerful as the dragon, possessing supreme magic power.

Later, he named the city he built after the word dragon blood.

Thousands of years have passed, the blood emperor has rarely appeared in front of the world.

Now, he has appeared.

However, he did not appear in front of outsiders, but in front of his son Xue Xuan.

"father!"

Xue Xuan looked at his father's tall figure, blood-red hair and face, admired and envious, if only he could step into the Devil Emperor Realm.

"Xue Xuan, there are only ten years left before Ran Gu's Secret Store opens, are you ready?" Xue Kun asked lightly.

"Father, the child has entered the Demon King's Mirror as early as a few years ago, and his strength has improved a lot. In the same realm, except for people like Beiming and Demon Lingzi, there are few people who can match the child. Therefore, father Don't worry." Xue Xuan replied confidently.

"Seeing that you are so confident, I feel relieved for my father. However, if you want to gain the inheritance of Demon Emperor Rangu, it is far from enough to have strong strength. What you have to do in the next ten years is to realize You can understand the way of heaven, understand the changes in the world and everything, and the truth of existence, so that you have such a glimmer of hope to obtain the inheritance of Demon Emperor Rangu, otherwise, everything is in vain." Xue Kun said solemnly.

"Baby understand." Xue Xuan replied earnestly.

"Well, you continue to practice." Xue Kun nodded and turned to leave.

"This time I must get the inheritance of Demon Emperor Ran Gu." Xue Xuan thought with a fist.

...

Yongcheng!

Somewhere in the palace stood a middle-aged man with a height different from ordinary people with blue eyebrows and green eyes, and a green magic pattern on the eyebrows, shaped like a magic tree, full of vitality.

"Father, I don't know what will happen to you calling the baby?"

In front of him, respectfully stood a young man with **** eyes, a wooden temple.

Then, the identity of this middle-aged man is self-evident, he is the lord of Yongcheng, the father of Mucha, and Muyong Demon Emperor.

"Musha, you don't need to find that human cultivator Lu Chen personally in the future, let's practice well next." Mu Yong Demon Emperor said.

"Father, I want to find Lu Chen and avenge my younger brother." Mu Sha said coldly.

"For my father, I know your feelings. Similarly, for my father, I can't wait to smash that Lu Chen's corpse immediately to avenge your brother Musu, but you must know that in ten years, Ran Gu's secret store will be opened again. For the father, I need you to get your inheritance from the Demon Emperor Rangu, and his perception of the fifth devil's robbery. This is very important for the father." Mu Yong said in a deep voice.

"Father, are you not even sure to survive the fifth Devil Tribulation?" Mu Sha was shocked.

"No, the more the Devil Emperor Jie goes, the more difficult it will be to get through it. If you want to get over it, it will be extremely difficult, let alone being a father, even the Devil Emperors like Bone Luo and Killing Gu will not be sure to break through. "Mu Yong Demon Emperor shook his head and said.

"Father, the child doesn't need to find Lu Chen personally, but I hope that you can continue to send someone to find this person, and vowed to avenge his younger brother." Mu Sha said solemnly.

"Don't worry about this, Musu is your younger brother, and even the second son of my Mu Yong Demon Emperor. Whoever kills him will have to pay the price of blood." Mu Yong Demon Emperor nodded and said.

"The kid went to practice." Mu Sha said.

"Go, ten years later, Ran Gu's Secret Vault will be opened, my father will inform you in advance." Mu Yong Demon Emperor waved and said.

"Yes." Mucha turned and left, and began to practice in retreat, preparing for the opening of Ran Gu's secret.

Seeing Mu Sha left, Mu Yong Mo Emperor disappeared in the palace, not knowing where he went.
