That person was originally also a genius, from the Divine Power Period all the way to the middle stage of the Inner Dan, it took less than a thousand years before and after, and among the six major Xuanmen, this speed was also considered a resource.

Unexpectedly, after the middle stage of the Inner Dan, it was difficult to make progress, and it took more than a thousand years to still be in the middle of the Inner Dan.

Seeing that the mid-stage life span of Neidan was getting closer and closer, this guy was furious and actually thought of refining Neidan.

Even if you can't practice Neidan below Neidan, then it should be no problem for me to practice Neidan above and above, right?

He tried his best to kill a Neidan Xuanshi, and after preparing for a while, he finally made up his mind to practice Neidan.

No one expected that he would really succeed, not only successfully cultivating the Inner Dan, but also being promoted to the late stage of the Inner Dan in one fell swoop, and his strength increased greatly.

At that time, he was simply overjoyed, you must know that the success of this matter was no longer due to his own promotion to the late stage of Neidan, but his bold attempt, which was enough to leave his name in the history of Xuanmen.

Because of him, the Xuanmen of the world know that the original Inner Dan period can practice the Inner Dan and get great benefits.

Before him, for countless years in the Heavenly Emperor Continent, the only one who could leave a name in the history of Xuanmen and let future generations admire it was the Heavenly Emperor.

And his attempts and discoveries have made him a big man who can look up to the Emperor of Heaven and live forever.

Although his strength was far inferior to that of the Heavenly Emperor, his discovery was enough to change the pattern of the entire Xuanmen.

∫，ww￡w.

After this news was revealed, the world's Xuanmen went crazy, so the masters above the Inner Dan began to look for the Inner Dan, digging up the Inner Dan to increase their cultivation, and everyone had to speed up the promotion and increase their strength.

The Heavenly Emperor Continent set off a bloody storm, and countless Neidan were killed.

Even psychics began to practice the Inner Dan, and it turned out that they could also enhance their strength.

This person has simply opened Pandora's box, the high-level Xuanshi in the world no longer uses the Xuanqi Pill as the main way of cultivation, everyone wants to kill people, dig up the Inner Dan, and use it for cultivation, which is many times faster than eating the Xuanqi Pill.

However, the good times were short-lived.

Just when everyone was looking for Neidan and digging up Neidan to cultivate.

The person who killed the most has already practiced to the sixth Neidan.

This person was originally in the later stage of Neidan, killed six Neidans in a row, and secretly killed two of his fellow disciples, practiced six Neidans in one go, and finally succeeded in promoting to psychic.

At this moment, he was ecstatic and overjoyed.

He spent two thousand years in the late stage of Neidan without being promoted to psychics, but it only took more than half a year to hunt down six Neidan.

This promotion speed made him completely turn into a murderous maniac, and he only had Neidan in his eyes.

But the day after he was promoted to psychic, he suddenly blew himself up in his sect hall and turned to pieces.

The following days can be described as miserable, and many people who practiced many inner pills began to blow themselves up one by one and blew them up alive.

The more you practice the Inner Dan, the faster you will die.

No one escapes death.

In less than two years, all the people who practiced the Inner Dan blew themselves up and died.

According to the statistics of well-intentioned people, practicing a Neidan basically died by self-explosion two years later, and each more practice decreases by three months.

After basically practicing to eight Neidan, he died directly.

All those who practice the inner dan can't escape the fate of being blown up, and at this time, the world's Xuanmen woke up, this is all destined by God, there is never a shortcut to practice, you must follow the step, rely on your own efforts, and practice little by little.

There is no free lunch in the world, and all those who take shortcuts will be cursed by God and will not die well.

Since then, no one has practiced Neidan, and everyone knows that if you practice Neidan below Neidan, you will not be able to be promoted to Neidan for life, and if you practice Neidan above Neidan, you will definitely die.

This is the famous 'Neidan Incident' on the Heavenly Emperor Continent.

Now that hundreds of thousands of years have passed since this incident happened, the Xuanshi of the world have naturally forgotten about this matter, but after many new disciples of the sect get started, they will learn these experiences, that is, Neidan, which cannot be practiced.

Now that Yang Zhen wants to practice the inner dan of 'one sword', Ou Dubu brought up the old matter again, and hurriedly persuaded Yang Zhen.

You are now in the Inner Dan stage, and you will be in the Inner Dan stage to cultivate the Inner Dan, and in two years at most, you will blow yourself up and die.

Sounding terrifying, Yang Zhen was slightly stunned.

"Yang Zhen, when I first entered the Heavenly Emperor Sect, I also learned this allusion, every sect has learned it, have you not learned it in the Flawless Sword Sect?" He Chu'er was also worried about him, after all, he had not been to Neidan before, and he would not die if he practiced Neidan below, only that he could not be promoted to Neidan for life.

"Uh" After Yang Zhen entered the Flawless Sword Sect, he didn't participate in a few classes, and the only time he fought with Leng Chang'an, he abolished a fellow sect, and he almost never attended classes in the future.

It sounds a bit dangerous, but I said before that if you practice Neidan, you can't be promoted to Neidan for life, and I'm not promoted the same.

Yang Zhen didn't believe in allusions, and he knew that he was different from Cong, and he must be able to transcend this curse.

"Is there any other way for you to find the entrance here?" Yang Zhen asked Ou Dubu.

Ou Dubu shook his head helplessly.

"That's okay, wealth and danger are sought, I don't practice the Inner Dan, how can I dig out his memory, wait for me. "Yang Zhen said, whoosh, enter the Yandi Jade Seal.

"Do you dare to practice me?" 'One Sword' already knew that Yang Zhen wanted to train him, and the remaining will roared angrily: "You demon, I curse you if you can't die well if you practice Neidan, I curse you, I curse you and curse your whole body to shatter, and you can't die well."

"That's so much nonsense, murderers, people always kill them, when you kill me, you have to think that you will have today" Yang Zhen sneered, what curse, what fate, he never believed it, my fate is up to me.

"Give your secrets. "Boom, a stream of Xuan Qi poured into the Inner Dan, and Yang Zhen began to practice his Inner Dan.

"Ah" With the scream of Yijian's last will, his inner dan began to fade, and countless mystical qi, countless pictures and memories poured into Yang Zhen's mind.

So far, Yang Zhen has practiced countless inner pills, but this time he practiced 'One Sword' only to find that the encounters in 'One Sword' life were richer than any of the inner pills he had practiced before.

He is not the oldest, but the experience of his life is unusually bumpy and changeable.

From the memory of 'One Sword', Yang Zhen could also feel why he wanted to be a master who hid in the night and killed people like hemp.

He was born blind, he was born blind, his parents thought he was a freak, abandoned him in the wilderness, no one in the village adopted him, and finally a she-wolf took him away.

The she-wolf brought him to the age of three, he could only crawl on the ground, after which the she-wolf was hunted and he was rescued from the mountains.

But leaving the mountains is not a good thing, just the beginning of another nightmare.

He was sold to an acrobatic troupe, which traveled all over the world, and 'Yijian' was treated as a wolf child, training all kinds of acrobatics to please the audience, and eating the same animals in the acrobatic troupe every day.

The growth of 'One Sword' was a human tragedy, so much so that he later became a Xuanshi, and did not join a famous sect such as the Heavenly Emperor Sect's Flawless Sword Sect, but chose the Dark Demon Gate.

He took pleasure in killing, hid in the darkness of the night, and slaughtered everyone he didn't like.

He even returned to the village where he was born after becoming a Xuanshi and slaughtered the entire village, including his own family.

After he became the Four Little Demon Kings of the Dark Demon Gate, he also ordered all the dynasties in the Dark Demon Gate, as long as it was a juggling folk team, to be arrested and beheaded.

The more people Yang Zhen got the 'One Sword', the more he felt that this person was a little pitiful.

The so-called poor man must have something to hate, and his growth formed his distorted personality, and in the end he became a murderous madman.

Yang Zhen saw that in the depths of his memory, many fellow disciples of the Dark Demon Gate were secretly attacked and killed by him because of a little conflict with him.

'One Sword' wanted to kill Yang Zhen, not because Yang Zhen had the Emperor of Heaven and Earth, but because he heard that Ou Dubu wanted to cooperate with Yang Zhen, in his opinion, this was Ou Dubu looking down on him, so he suddenly wanted to kill Yang Zhen.

The memories of 'One Sword' appeared in Yang Zhen's mind one by one, and Yang Zhen's Xuan Qi was also increasing.

Suddenly, boom, in Yang Zhen's mind, there was a loud bang, and an unusually majestic hall appeared.

This hall is the most majestic hall that Yang Zhen has seen so far in his life, it is even bigger than the barbarian house, it seems to be inhabited by the gods, and it does not belong to the world.

The gate of the main hall is dozens of zhang high, and it is densely packed with countless portraits, each of which looks like a demon and a monster.

"A treasure trove of darkness. Yang Zhen exclaimed.

This is the dark treasure left behind by the ancient Dark Lord.

'One Sword' has seen the dark treasury.

Just before Yang Zhen and Ou Dubu came, Ximen Yijian had already found the door of the dark treasure house, but he couldn't get in, and then found that Yang Zhen and Ou Dubu were coming, so he retreated.

There really is a treasure trove of darkness.

Yang Zhen stared at the dark treasure house in his mind, the door of the treasure house was closed, and all the ancient gods and demons were painted on it.

Suddenly, all the gods and demons seemed to have been resurrected, and 'wow roar' was in Yang Zhen's mind, and at the same time, they roared wildly.

Yang Zhen even felt the inside of the treasure house door, brushing, a vision came through, and saw Yang Zhen's mind.

"Ah" Yang Zhenzhen trembled and woke up violently.

When I looked down, I saw that the inner dan in my hand had disappeared.

The 'One Sword' had already been completely cultivated and killed by him, and Yang Zhen had increased nearly forty million Xuan Qi this time.

"What's wrong, Yang Zhen. "He Chu'er came over, Yang Zhen has not been so shocked as he is today.

"It's okay, it's okay, let's go, I've found the location of the Dark Vault. Yang Zhen settled down and left the Yandi Jade Seal.

Outside, Ou Dubu was sitting cross-legged, resting with his eyes closed, and when he saw Yang Zhen coming out, he hurriedly got up.

"I found the location of the treasure house, but you said that you had told Ximen Yijian how to open the treasure house, why didn't he open it?" Yang Zhen was puzzled, he saw the door of the treasure house from the memory of 'Yijian', but Ximen Yijian didn't seem to try to open the treasure house.

Ou Dubu shook his head, looking dazed.

Simon Yijian is not a good person, if he can open the treasure house, he must have opened it a long time ago, what happened to the bottom and let them retreat?

Yang Zhen thought of the pair of eyes in the treasure house, and saw Yang Zhen's mind through the heavy door of the treasure house, which made Yang Zhen feel that he was being stared at by others.

Now that I think about it, it seems that the eyes are still looking at themselves.

Could it be that there is someone in the treasury?

Therefore, Simon did not dare to open the treasure house with a sword, and immediately retreated.

This is a dark treasure house, it has existed since ancient times, if there are people in the treasure house, it must be ancient gods and demons, comparable to the existence of the god realm, powerful and terrifying.

"Then should we go or not?" Ou Dubu asked Yang Zhen.

Yang Zhen thought about it, and it was still the same sentence, wealth and danger are sought, and the courage is not big, how to get rich.

"Let's go, at least go see the treasure trove. ”
