These fairy stones were obtained from the cave left by the predecessors together with the machine beasts. Except for the necessary strengthening formations, Chen Feng has been reluctant to use them because the number of fairy stones is really small.

But at this moment, in order to let this ninth-level spiritual vein evolve as quickly as possible, Chen Feng also risked his life.

Although he may lose this batch of immortal stones, if the ninth-level spiritual veins successfully evolve, he will get an immortal vein, which will undoubtedly bring him a thousand-fold reward.

Chen Feng felt excited just thinking about cultivating immortal veins.

The dragon-shaped patterns on the wall were flashing purple light crazily, as if they were extremely excited to see these fairy stones.

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

"boom--"

Boundless energy rises from the broken reality. It is the purest fairy power, the spiritual energy that belongs only to the fairy world. At this moment, these fairy powers seem to be guided, and they all move towards the dragon shape.

The lines flow away.

The purple light on the dragon-shaped body became brighter and brighter, almost piercing Chen Feng's eyes.

Chen Feng didn't hesitate at all, he just crushed the fairy stones one by one. The boundless fairy spirit sprayed out from the fairy stones and was absorbed crazily by the dragon-shaped lines.

Just like that, when Chen Feng crushed the thirty-second one, the dragon-shaped pattern suddenly exploded with a roar and turned into dense purple light spots. Each of these purple light spots contained extremely powerful

The powerful force made even Chen Feng turn his attention to it.

"call--"

A breeze suddenly started blowing around with a purple light spot at the center.

Then, Chen Feng felt a strong flow of fairy spirit coming towards his face. These fairy spirits were quite pure, and if he could absorb them, he would definitely be able to achieve a big breakthrough.

"Haha, it's finally done!" Chen Feng clenched his hands into fists, with a look of ecstasy on his face that showed how excited he was.

I saw countless purple light spots constantly exchanging positions, as if they were arranging troops, forming a pattern in an instant. It was a lifelike purple dragon shadow, and every inch of the scales was clearly visible. The vigorous dragon

The drive seemed to contain quite powerful energy, and the sharp dragon claws shone with little bits of cold light, as if they were real.

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

.

Waves of ethereal aura continued to emanate from the dragon-shaped carvings, and soon filled the entire secret room. It didn't take too much, and the entire Tiandan Immortal Mansion would be covered by the rich aura of the fairy spirit.

"The aura of fairy spirits is really many times more powerful than the ordinary spiritual energy in the world of cultivation. If one can practice for a long time in the rich aura of fairy spirits, even a fool can practice to the Mahayana stage and overcome tribulations.

Ascension." Chen Feng sighed, but his face was full of excitement: "From now on, my Tiandan Immortal Mansion is a place of immortal veins, and practicing here is like cultivating in an immortal vein.

"

Once again experiencing the wonder of the fairy spirit, Chen Feng flashed and arrived at the main hall.

Ru Lan stood quietly in the main hall, as if waiting for Chen Feng. Seeing Chen Feng stand out, Ru Lan said with surprise: "Chen Feng, just now, the spiritual energy of heaven and earth here seemed to have disappeared. However,

It seems that a more profound spiritual energy suddenly appeared."

While speaking, Ru Lan suddenly raised her brows: "This spiritual energy is so powerful. I'm practicing here. It won't take long for me to break through."

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

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

Then, Chen Feng told Ru Lan what was going on outside. When Ru Lan heard that Chen Feng's parents had been killed, she immediately separated and hurriedly asked Chen Feng to send her out of the Tiandan Immortal Mansion.

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

Chen Feng did not go back. After saying goodbye to Ru Lan, Chen Feng found a low-lying place.

This low-lying area is deep in the ancestral tomb mountain, and usually no one would come in. It was from here that Chen Feng entered the underworld and rescued the ghosts of his parents.

When the sword energy was unleashed, a crack more than two meters deep opened in the earth. Along with the earth, there was also the space where the earth was located.

In the crack, a dark space crack is standing quietly, like a mouth that bites people, and a billowing cold breath flows out from this space crack.

This space crack is the way to enter the underworld.

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

According to legend, millions of years ago, there was no reincarnation in the world of cultivation. After people died, they existed in the world as Yin spirits.

But Yin spirits are different from humans after all. As soul bodies, they are often persecuted by monks. Although Yin spirits can also practice, their cultivation speed cannot be compared with human monks. Therefore, even among Yin spirits, there are many powerful ones.

However, it is still no match for human conquest.

Until a peerless strong man appeared among the Yin spirits. In order to prevent the Yin spirits from being persecuted by humans, he used his overwhelming power to carve out an independent small world from the endless space. This small world,

It was the predecessor of the underworld.

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

Later, that strong man created the Six Paths of Reincarnation, allowing the Yin spirit to enter reincarnation again, transform into the purest soul and enter the world of cultivation, and be reincarnated as a human being.

As time goes by, the relationship between the underworld and the world of cultivation becomes closer. As long as their souls are not scattered, many of the dead monks will enter the underworld and be reincarnated again.

However, except for Yin spirits who can enter the Underworld, ordinary monks cannot enter the Underworld at all, because most of them do not know the coordinates of the Underworld. Even if they know the coordinates, they cannot reach it without strong strength.

Chen Feng also obtained the coordinates of the Underworld from his disciples. His third apprentice, Cui Jue, was the judge of the Underworld, so he naturally knew the coordinates of the Underworld.

After tearing open the spatial rift, Chen Feng stepped out and with a movement of his body, he was submerged in the spatial rift.
