It is a completely sealed room. Closed on six sides, no doors and no windows. All around, there were faint traces of circles and circles.

In the middle of the room, a cyan futon lay quietly, the futon was unpretentious, and everywhere was full of traces of time.

Suddenly, the futon emitted a dense red light, and then, a deep black crack suddenly opened above the red light, like a small door, connecting the endless void.

Not long after the crack appeared, a tall figure stepped out of the crack and landed on the futon in the air, gently dragging it down by the dense red light.

Immediately, the crack disappeared, and there was no trace left. In the sealed dark room, only Chen Feng was left.

Chen Feng stepped down from the dense red light and landed on the ground, and then, the red light slowly disappeared, taking away the last bit of light in the room.

"Where is this?" Chen Feng looked around, slightly surprised. In the False Dan Period, he was already able to see things at night, and in Chen Feng's observation, the surrounding scenes were presented in front of his eyes.

Or rather, this is an alchemy room. Not far from the futon, an unpretentious Danding was lying there quietly, without a trace of fireworks.

Next to the Dan stove is a wooden table. On the wooden table, there were a few things faintly.

That's all. Except for a Dan furnace, a wooden table, and a futon, there was nothing else in this room.

"Judging from the method of entering here, this place is definitely an important place in the secret realm, and what can exist here must not be bad!" Chen Feng's heart moved, and he walked to the wooden table in a few steps.

There weren't many things on the wooden table, just two things, a jade plaque, a book bound in thread, and nothing else.

Chen Feng gently picked up the book on the table. I don't know how long this book has been sleeping here, and it is covered with a thick layer of dust, as if it is a peerless beauty covered with a veil, so that Chen Feng can't help but reach out and wipe the dust on it.

I don't know what kind of monster skin the book is made of, and it is smooth to the touch, but it is smooth. On the dark yellow cover, several vigorous and powerful gold characters are impressive.

"Tiandan Record?" Chen Feng chewed these three words carefully, and the ecstasy in his eyes became brighter and brighter: "Could it be that this is an alchemy notebook left by predecessors"

Since ancient times, the most precious thing for an alchemist is not the Danfang, but the alchemy notes of the alchemist. These alchemy notes contain the alchemist's lifelong understanding of alchemy, which can be described as the essence of the alchemist's knowledge.

"I don't know, what level the alchemist who wrote this alchemy note is. Holding back the ecstasy in his heart, Chen Feng cautiously opened the first page of the "Tiandan Transcript".

"Boom-" Just opened it, and a magnificent picture suddenly appeared in front of Chen Feng's eyes.

It was a deep starry sky, with endless bright stars surrounding Chen Feng, not colliding with sparks that destroyed the world......

Just as Chen Feng was frightened, an old and majestic voice slowly sounded: "Dan can live forever, medicine comes back to life, the gods and Buddhas in the sky bow their heads, and the heaven and earth of Dingzhen are all over!

"Seek the ultimate Dan Dao and achieve the supreme Dan Dao?" that majestic voice caused an uproar in Chen Feng's heart. Since ancient times, that alchemist had not aimed at this, even if Chen Feng had been a Dan Ancestor in the cultivation realm in his previous life, he still continued to pursue it in order to reach a more profound realm.

"Okay, I'd like to see how far I can go with this "Tiandan Record"!" This time, Chen Feng's heart swelled with unprecedented confidence, and his determination to pursue the Supreme Dan Dao in his heart became even more tenacious.

With the birth of Chen Feng's idea, a quaint Danding suddenly appeared in the infinite starry sky. Danding is pitch black, as deep as a black hole, as soon as it appears, it makes people feel like they are standing up to the sky.

"This is ......" Chen Feng's heart twitched violently, he was extremely familiar with the big ding that had just appeared, and even knew every trace of it well!

"Void Danding, isn't this the Void Danding?" At this moment, the regret in Chen Feng's heart was incomprehensible, the Void Danding that he had been with day and night in his previous life actually appeared here, and looking at the appearance of the Void Danding at this moment, it was still so earth-shattering, as if it was the master of this universe starry sky.

"Hum-" At the moment when Chen Feng was extremely surprised, the Void Danding suddenly trembled slightly, and then, in the Void Danding, a sudden surge of brilliance, a hazy, chaotic brilliance.

"It's a flame!" Chen Feng's heart moved, and this chaotic brilliance was emitted by the raging flames inside the Void Danding.

Even though he knew that the scene he saw in front of him was fake, Chen Feng still felt that this flame was extremely powerful, and the power emitted from it seemed that even heaven and earth could dissolve!

"What a powerful flame!" Chen Feng's heart faintly throbbed, and even the earth soul fire in his body couldn't help but become active, and the red and orange color began to gradually become richer, and the evolution to the Heavenly Spirit Orange Fire also accelerated.

In this way, Chen Feng began to indulge in the chaotic and hazy flames, as if he had forgotten time and space, and his body gradually swayed like the flames in the Void Danding.

This is the rhythm of the flames.

I don't know how long it took, the Void Danding slammed into a shock, and this shock woke up Chen Feng's mind.

Then, a pale orange flame appeared in Chen Feng's palm, and the flames danced and swayed, with an indescribable agility.

"Unexpectedly, just by observing the flame of the Void Danding, my Earth Soul Fire completely evolved into the Heavenly Spirit Orange Fire. It's a pity, if I can comprehend it for a while longer, my Heavenly Spirit Orange Fire will definitely come to fruition...... However, being able to make Tianling Orange Fire Xiaocheng is already an unexpected harvest. Chen Feng had a faint sense of satisfaction in his heart: "I don't know what level of flame the flame in this Void Danding is, it has such great power." ”

At this moment, an old voice sounded again, like a murmur in a sleep, and as if it was a chanting of a dying old monk, and the words again completely attracted Chen Feng's heart.

"These voices are all Dan Dao Zhizhi, any sentence makes many of my doubts cheerful...... Chen Feng's eyes were full of piety, that was the belief in the supreme Dan Dao, at this moment, he was completely intoxicated by this simple and obscure voice......
