These immortal stones were obtained from the cave left by the predecessors along with the trap beasts, except for the necessary strengthening formations, Chen Feng has been reluctant to use them, because the number of immortal stones is really not much.

However, at this moment, in order to let this ninth-rank spiritual vein evolve as soon as possible, Chen Feng also let it go.

Although he may lose this batch of immortal stones, if the ninth-rank spirit vein successfully evolves, then he will get an immortal vein, which will undoubtedly bring him a thousandfold report.

With the cultivation of immortal veins, Chen Feng felt excited when he thought about it.

The dragon-shaped patterns on the walls flickered with purple light frantically, as if they were extremely excited to see these immortal stones.

"Can't wait?" Chen Feng smiled faintly, and with force in his hand, the immortal stone was crushed by him.

"Boom-"

Boundless energy rose from the shattered reality, which was the purest immortal power, and it only belonged to the aura of the immortal realm. At this moment, the power of these immortals seemed to be guided, and they all rushed towards the dragon-shaped pattern.

The purple light on the dragon-shaped body became brighter and brighter, almost stabbing Chen Feng from opening his eyes.

Chen Feng didn't hesitate, he just pinched and exploded the immortal stones one after another, and the boundless immortal qi continued to spew out from the immortal stones, and was frantically absorbed by the dragon-shaped pattern.

In this way, when Chen Feng crushed the thirty-second one, the dragon-shaped pattern suddenly boomed, and it exploded, turning into dense purple points of light. Each of these purple points of light contained extremely powerful power, and even Chen Feng was stunned by it.

"Whew-"

A breeze suddenly centered on the purple point of light and continued to blow in all directions.

Then, Chen Feng felt a strong immortal aura rushing to his face. These immortal qi are quite pure, and if they can absorb them, they will definitely be able to make a big breakthrough.

"Haha, it's finally done!" Chen Feng clenched his hands into fists, and his face showed ecstasy, and he could see how excited he was in his heart.

I saw countless purple points of light constantly changing positions, as if they were arranging troops, and a pattern was formed in an instant. It was a lifelike purple dragon shadow, every inch of the scales was clearly visible, the vigorous dragon drive seemed to contain quite powerful energy, and the sharp dragon claws were even flickering with a little cold light, as if it were substance.

In Chen Feng's expectant gaze, the dragon shadow roared, and then its body moved, crashing towards the wall. Suddenly, the dragon shadow merged into the wall and turned into a dragon-shaped carving, with teeth and claws, extremely domineering.

An ethereal aura emanated from the dragon-shaped carvings, and soon filled the entire secret room. It doesn't take too much, and the entire Tiandan Immortal Mansion will be covered with a strong immortal aura.

"The immortal qi, if it is really stronger than the ordinary aura of the cultivation realm, I don't know how many times, if you can cultivate for a long time in the rich immortal qi, even if you are a fool, you can cultivate to the Mahayana period and ascend through the tribulation. Chen Feng sighed with emotion, but his face was full of excitement: "From now on, my Tiandan Immortal Mansion is a place of immortal veins, and cultivating here is like cultivating in an immortal vein." ”

Experiencing the wonder of the fairy aura again, Chen Feng's figure flashed and came to the top of the main hall.

Ru Lan stood quietly on the main hall, as if waiting for Chen Feng. Seeing Chen Feng stand out, Ru Lan said with surprise: "Chen Feng, just now, the aura of heaven and earth in this seems to have disappeared, but it seems that a more profound aura has suddenly appeared. ”

While speaking, Ru Lan's eyebrows suddenly lifted: "This aura is so powerful, I am cultivating here, it won't take too long to break through." ”

Chen Feng nodded and said solemnly: "Ru Lan, except for some of our closest people, the aura of this place can't be mentioned to anyone, understand?"

Seeing Chen Feng's solemn tone, Ru Lan nodded obediently.

Then, Chen Feng told Ru Lan about the outside affairs, and when Ru Lan heard that Chen Feng's parents were both killed, she was immediately separated, and was busy asking Chen Feng to send her out of Tiandan Immortal Mansion.

Chen Feng did not refuse, and both left the Tiandan Immortal Mansion with Ru Lan, and asked her to go to Chenjiagou to meet Li Li and Xiao Lin on her own.

Chen Feng didn't go back, and after saying goodbye to Rulan, Chen Feng found a low-lying place.

This low-lying area is deep in the ancestral tomb mountain, and no one usually comes in at all. Chen Feng is going to enter the underworld from here and save his parents' yin spirits.

As soon as the sword qi was long, the earth cracked open a crack more than two meters deep. Cracked with the earth, there is also the space where the earth is located.

In the crack, a swarthy spatial crack was quietly staying, like a big mouth devouring people, and a billowing cold aura flowed out of this spatial crack.

This spatial crack is the way to enter the Netherworld.

The Netherworld is actually a strange little world. It is parallel to the cultivation realm, independent of each other, but complementary to each other.

According to legend, millions of years ago, there was no reincarnation in the cultivation realm, and after people died, they existed as yin spirits.

But after all, Yin Spirits are different from humans, and as soul bodies, they are often persecuted by monks. Although Yin Spirits can also cultivate, their cultivation speed cannot be compared to that of human cultivators. Therefore, even though there are many strong people among the Yin Spirits, they are still no match for the human conquest.

Until a peerless powerhouse appeared among the Yin Spirits, in order to prevent the Yin Spirits from being persecuted by humans, he opened an independent small world from the endless space with his absolute strength. This small world is the predecessor of the Netherworld.

Under his leadership, all the Yin Spirits entered this small world.

Later, that strong man created the Six Realms of Reincarnation, allowing the Yin Spirit to re-enter reincarnation, turn into a wisp of the purest soul and devote himself to the cultivation realm, and reincarnate as a human being.

With the precipitation of time, the relationship between the Netherworld and the cultivation realm has become closer, as long as the soul is not scattered, many of those dead monks will enter the Netherworld and reincarnate again.

However, except for the Yin Spirits who can enter the Netherworld, ordinary monks cannot enter the Netherworld at all, because most of them don't know the coordinates of the Netherworld. Even if you know the coordinates, you can't reach it without the strength of the strong.

And Chen Feng also got the coordinates of the Netherworld from his apprentice. His third apprentice, Cui Jue, is the judge of the Netherworld, and he naturally knows the coordinates of the Netherworld.

Tearing open the spatial crack, Chen Feng stepped out, and as soon as his body moved, he was drowned in the spatial crack.

The spatial rift slowly closed as if it had never existed, leaving only a large sword mark to prove that something had happened here.
