These immortal stones were obtained together with the mechanical beasts from a cave left behind by the predecessors. Except for the necessary reinforcement of the formation, Chen Feng has been reluctant to use them because the number of immortal stones is really small.
However, at this moment, in order to make this ninth-grade spiritual vein evolve as quickly as possible, Chen Feng also gave it his all.
Although he might lose this batch of immortal stones, if the ninth-grade spirit vein successfully evolves, he will obtain an immortal vein, which will undoubtedly bring him a thousand-fold return.
Chen Feng felt excited just thinking about having immortal veins to cultivate.
The dragon-shaped patterns on the wall were flashing purple light wildly, as if they were extremely excited to see these fairy stones.
"Can't wait?" Chen Feng smiled faintly, exerted force in his hands, and crushed the fairy stone heavily.
"boom-"
Boundless energy rose from the shattered reality. It was the purest immortal power, the spiritual energy that belonged only to the immortal world. At this moment, these immortal powers seemed to be guided and rushed towards the dragon-shaped pattern.
The purple light on the dragon-shaped body became brighter and brighter, almost blinding Chen Feng.
Chen Feng did not hesitate at all. He crushed the immortal stones one by one. Endless immortal energy continuously spurted out from the immortal stones and was madly absorbed by the dragon-shaped pattern.
Just like that, when Chen Feng crushed the thirty-second dragon, the dragon-shaped pattern suddenly exploded with a rumble, turning into dense purple light spots. Each of these purple light spots contained extremely powerful power, and even Chen Feng was surprised.
"call-"
A breeze suddenly blew around with the purple light spot as the center.
Then, Chen Feng felt a strong aura of immortal spirits coming towards him. This aura of immortal spirits was quite pure, and if he could absorb it, he would definitely be able to make a big breakthrough.
"Haha, it finally worked!" Chen Feng clenched his fists, his face showing ecstasy, and it was obvious how excited he was.
Countless purple light spots were constantly changing positions, like a battle array, and a pattern was formed in an instant. It was a lifelike purple dragon shadow, every inch of its scales were clearly visible, and its agile dragon body seemed to contain quite powerful energy, and its sharp claws were flashing with cold light, as if they were real.
Under Chen Feng's expectant gaze, the dragon roared, then moved and crashed into the wall. Suddenly, the dragon merged into the wall and turned into a dragon-shaped carving, baring its fangs and claws, and looking extremely domineering.
A stream of ethereal auras emanated from the dragon-shaped carvings, and soon filled the entire secret room. It didn't take too much for the entire Tiandan Immortal Mansion to be covered with a rich aura of immortal spirits.
"The immortal spirit is indeed many times stronger than the ordinary spiritual energy in the cultivation world. If one can cultivate for a long time in the rich immortal spirit, even a fool can cultivate to the Mahayana stage and transcend the tribulation to ascend to heaven." Chen Feng sighed with excitement on his face: "From now on, my Tiandan Immortal Mansion is a place of immortal veins. Practicing here is like practicing in an immortal vein."
After experiencing the wonder of the immortal spirit once again, Chen Feng flashed and arrived at the main hall.
Ru Lan stood quietly in the hall, as if waiting for Chen Feng. Seeing Chen Feng appear, Ru Lan said with surprise: "Chen Feng, just now, the spiritual energy of heaven and earth here seemed to have disappeared, but it seems that a more profound spiritual energy suddenly appeared."
As he spoke, Ru Lan's brows suddenly raised: "This spiritual energy is so powerful. If I practice here, it won't take too long for me to break through."
Chen Feng nodded and said solemnly: "Rulan, except for some of our closest people, the spiritual energy of this place cannot be mentioned to anyone else, understand?"
Seeing Chen Feng's serious tone, Ru Lan nodded obediently.
Then, Chen Feng told Ru Lan what happened outside. When Ru Lan heard that Chen Feng's parents were both killed, she became very upset and asked Chen Feng to send her out of Tiandan Immortal Mansion.
Chen Feng did not refuse, and he and Ru Lan left Tiandan Immortal Mansion together, and let her go to Chenjiagou on her own 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 grave mountain, and usually no one comes in. Chen Feng is going to enter the underworld from here to rescue the ghosts of his parents.
As the sword energy shot out, a crack more than two meters deep appeared on the ground. Along with the ground, the space where the ground was located also split open.
In the crack, a dark space crack was quietly staying, like a big mouth that could eat people, and a rolling and cold breath flowed out from the 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 spirits.
But Yin spirits are different from humans after all. As souls, they are often persecuted by monks. Although Yin spirits can also practice, their practice speed cannot be compared with that of human monks. Therefore, even though there are many strong ones among Yin spirits, they are still no match for human conquest.
Until a peerless strongman appeared among the Yin spirits. In order to prevent the Yin spirits from being persecuted by humans, he used his powerful strength to create an independent small world from the endless space. This small world was the predecessor of the underworld.
Under his leadership, all the ghosts entered this small world.
Later, that powerful man created the Six Paths of Reincarnation, allowing the evil spirits to re-enter the cycle of reincarnation, transforming into the purest soul and entering the world of cultivation, to be reborn as human beings.
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 dead cultivators will enter the underworld and reincarnate again.
However, except for the ghosts, ordinary cultivators 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 got the coordinates of the underworld from his apprentice. His third apprentice, Cui Jue, was the judge of the underworld and naturally knew the coordinates of the underworld.
After tearing open the space crack, Chen Feng took a step forward, and as his body moved, he was submerged in the space crack.
The space crack slowly closed, as if it had never appeared, leaving only a huge sword mark to prove what had happened here.
