Because there were too many things during this time, Chen Fan hadn't retreated for a long time.

Just take advantage of this time to practice and consolidate it.

It took most of the day to familiarize myself with the secret method, and I began to study the Dragon Heart Sutra.

Chen Fan has studied other secret methods for a long time, and it is difficult to improve them at least for a while, but the Dragon Heart Sutra is different, and it was rarely used before for various reasons, so Chen Fan really didn't know much about this set of exercises.

Therefore, the main purpose of Chen Fan's retreat this time is to familiarize himself with the Dragon Heart Sutra, hoping to win more life-saving methods for himself.

The Dragon Heart Sutra is also the Leng family's top-secret secret method, although he doesn't know the corresponding secret technique, but just that half-dragon body is enough for Chen Fan to improve his chances of survival.

Although there is still Leng Yunhai, a member of the Leng family, in this operation, Chen Fan is really not afraid of this guy, and even if there is a chance, Chen Fan will definitely kill him, and find a way to get something about the Leng family out of his mouth.

After all, Lin Muqing had also said before that this Leng Yunhai was not a good thing, plus what had happened before, so Chen Hao never thought of letting this Leng Yunhai leave Biyou Palace.

If he finds out that this guy is not so bad later, Chen Hao also has the means to keep him shut up, and he will never be able to say things that should not be said.

As time slowly passed, with the foundation that Chen Fan had accumulated during this time, it took less than a day for the Dragon Heart Sutra to completely open and rush all the way to the fifth layer.

Now that Chen Fan has cast the Dragon Heart Sutra, it can be seen that the layers of dragon scales on his body are flashing with a trace of pitch-black luster, especially the dragon tail, which is even more hideous and terrifying.

After doing all this, Chen Fan looked at the token that Guiyi handed him.

He was thinking about whether he wanted to refine it!

After all, this is something given to him by Guiyi, and the risk of refining is too high, if he can't say it accurately, he may fall into the layout of Guiyi.

But having said that, the level of risk in Biyou Palace this time is still too high.

Even if he had the Dragon Transformation Heart Sutra and had cultivated to the fifth layer, he still didn't have any bottom in his heart.

After all, there are some things that Chen Fan didn't elaborate on before.

Not to mention that the time of the earth's seal was unsealed at an accelerated pace, and it had even reached a terrifying level, just to say that the spirit born from the Four Swords of Zhuxian alone gave Chen Fan a sense of urgency.

After all, as a Demon Venerable in his previous life, he naturally knew more things than ordinary people, so he knew very well how strong this ancient powerhouse's treasure was, and the most important thing was that the spirit born from this treasure weapon could automatically receive some ancient information from heaven and earth as soon as he had spiritual wisdom.

This is called being born to know.

The operation of some powerful treasures, as well as the hidden ...... between heaven and earth

Even the true top-notch machine spirit, at the moment of birth, the ancient will of heaven and earth will automatically give the cultivation method, and this cultivation method is also the most suitable cultivation method for the machine spirit.

To put it simply, these machine spirits can be cultivated independently.

This is also the most terrifying thing.

You must know that what Chen Fan said is still the top machine spirit in the heavens and ten thousand realms, and the current situation on the earth is countless times more complicated than this situation.

After all, the ancient earth was in ancient times, and even more distant years, but it was the center of the heavens and all the worlds, and the holy land in the hearts of all cultivators, so the horror of this place was far more numerous times than that of the heavens and all the worlds.

The spirits of the heavens and all the worlds can do all this, but what about the machine spirits of the top powerhouses of the ancient earth?

Even if Chen Fan was stupid, he understood that he must be stronger than the spirits in other parts of the Heavens and Ten Thousand Realms.

Not to mention the palace master of Biyou Palace, Tongtian Sect Master, that is placed on the ancient earth

In addition to the strange opening of Biyou Palace this time, Chen Fan naturally had a rather bad premonition.

After all, for such a long time, the top blessed land like Biyou Palace, according to common sense, should be the latest batch to open, after all, this is the dojo of the top powerhouse in ancient times, how can the seal in it be so easy to unlock?

But now the strange thing is that Biyou Palace is actually opened like this, if there is nothing greasy in it, then even if Chen Fan is killed, he will not believe it.

Therefore, even if he doesn't know the specific situation, Chen Fan can now be sure that there are definitely some calculations that he doesn't know, just waiting for their group of pigs to rush in stupidly.

Although it is not clear who is laying out, in the face of this level of layout, even Chen Fan can feel the hidden danger.

Therefore, the more means of saving life, the better!

However, with the pass token of Biyou Palace in front of him, Chen Fan was really not sure for a while, whether he wanted to refine it or not?

After all, if there is no problem, then having such a pass token of Biyou Palace will definitely give you a lot less trouble, but if there is fraud in it, then maybe you can only make a wedding dress for others.

Therefore, Chen Fan is very cautious.

To be honest, he didn't think about leaving directly and staying away from this crisis completely, after all, with his current cultivation, if he really wanted to leave, no one really could stop him.

But he finally decided to stay, this was really not because Chen Fan showed face before, and he really wanted to explore it carefully to see what the layout of this Biyou Palace was.

After all, if you don't enter the tiger's den, you can get the tiger!

The current situation itself is very bad, the crisis from the heavens and all the worlds is like a mountain pressing on his heart, and now there is such a strange situation on the earth......

If he can't know this, or even prepare in advance, or even plan in advance, then one step at a time, and what awaits him in the end will inevitably be a situation of death.

Therefore, even if he knew that there was a problem in this Biyou Palace, he still chose to go in, ready to take a good look at the layout of who was in it, and explore the truth about the revival of the earth's aura, so as to make plans as soon as possible.

"Forget it, let's fight it!"

Chen Fan muttered: "Anyway, if you don't grow in the crisis now, then you won't even have a chance to grow in the end." ”

"Isn't it just a pass token, I want to see if the means of unification can really trap me!"

Thinking of this, Chen Fan was not embarrassed, and directly wrapped the dusty token in front of him with spiritual power, and then directly began to forcibly refine it.

With the hazy flow of spiritual power, Chen Fan completely fell into cultivation.

On the other side, Gui Yi sat in a quaint room, with a faint mist steaming in front of him, forming a huge mirror, which revealed the scene of Chen Fan's cultivation.

In the end, the moment he saw Chen Fan start refining this token, the corners of his mouth gradually revealed a shallow smile, but the eyes were extremely cold.
