With a flash of green light, the formation behind Chen Feng closed again.

As for Chen Feng, he was already standing within the seventh level spirit vein.

Closing his eyes, Chen Feng took in a deep breath of the rich spiritual energy, full of nostalgia.

In his past life, he had a huge foundation, and he also had a seventh grade spirit vein. He could even cultivate and refine pills under the spiritual energy of a grade seven spirit vein every day.

After his rebirth, he had become completely poor, without any cultivation resources. However, this enormous contrast did not cause Chen Feng to become discouraged. Instead, it ignited his fighting spirit, returning it to its peak state.

Now that he had stepped into the realm of the seventh grade spirit vein once more, he felt a sense of sadness. Unknowingly, he was getting closer and closer to his former realm. He believed that he would soon be able to return to his former peak and even surpass his former realm.

With a long sigh, Chen Feng opened his eyes and a brilliant light shone from his eyes. With this sigh, his mental state had actually improved, and he had become much more determined towards the future.

"It hasn't been mined in decades, and sure enough, there are plenty of Spirit Stones." Chen Feng surveyed his surroundings and nodded his head in satisfaction.

Furthermore, the most inferior spirit stones here were actually mid-ranked spirit stones. The depths of the spirit vein area were filled with high-grade spirit stones, and the quality was also quite high.

However, Chen Feng did not find any top grade spirit stones.

"It looks like top quality spirit stones can only be found and not sought. I'm afraid that even a spirit vein of the eighth level may not exist." Perhaps only the supreme grade nine spirit vein would be able to give birth to top grade spirit stones. "

The ninth level spirit vein only existed in the legends of the cultivation world. If it wasn't for the fact that there was an ancient book stating that there was a ninth grade spirit vein, the cultivators of the cultivation world would have long ago reclassified the spirit veins.

Looking at the large amount of spirit stones in front of him, even though Chen Feng had a firm heart, he could not help but become somewhat fanatical. At this moment, the amount of spirit stones contained here was something that anyone would go crazy over if they saw it, not to mention someone like Chen Feng, who used spirit stones like flowing water. One had to know that Chen Feng was a tiger that ate spirit stones. No matter how much time he spent, it would all be quickly used up.

However, in the end, Chen Feng still suppressed the greed in his heart. Holding his breath, he focused his mind and sank his consciousness into the Heavenly Pill Immortal Manor within his dantian.

"A seventh grade spirit vein possesses intelligence and cannot be collected by the Spirit Storage Kettle. "However, my Heavenly Pill Immortal Manor's grade is extremely high. The speed at which I collect spirit veins is much faster than the Spirit Storage Pot. I wonder if I can collect these seventh grade spirit veins." With this thought in mind, Chen Feng sent a command to the Heavenly Pill Immortal Manor.

The moment he sent out that thought, the Heavenly Pill Immortal Manor immediately started to shake. An extremely strong suction force abruptly burst out of Chen Feng's dantian, covering the entire spiritual vein.

In the blink of an eye, boundless spiritual energy rushed towards Chen Feng's dantian and was sucked into the Heavenly Pill Immortal Manor.

"Eh? Could it be that the Heavenly Pill Immortal Manor can only absorb the spiritual energy here, and not the spiritual vein? " A trace of regret flashed through Chen Feng's heart.

At this moment, the ground violently shook.

"There's hope!" Chen Feng felt a chill in his heart. His originally regretful mood was swept away as he looked at the surrounding mountain walls with rapt attention.

Countless pieces of crushed rock and dirt were falling down, as if an earthquake had occurred. Even the walls of the Spirit Vein had small cracks appear.

At the same time, Yi Tian Zong and Li Lingxi, who were standing outside the great array, were alarmed. They did not know what had happened because of the sudden tremor. They looked at the swaying great array with panic and doubt in their eyes.

ta ta ta ta … *

The sound of hurried but orderly footsteps rang out as the city guards that were guarding the spirit vein area felt the trembling of the mountain and rushed in.

"All of you, step down. This City Lord is fine!" Yi Tian Zong said in a deep voice, "Without my order, no one is allowed to enter. Otherwise, I will kill them all!"

Just as Yi Tian Zong's voice faded away, the orderly sounds of footsteps suddenly stopped and echoed again. However, at this moment, the sound of the footsteps grew further and further away. It was evident that the city guards had returned to the cave entrance and continued moving forward.

"Rumble ~ ~ ~"

The shaking of the mountain became more and more intense. Boundless amounts of crushed stone and dirt fell more and more frequently. The cracks on the walls of the spirit vein ground also became larger and larger, as if this cave could collapse at any moment.

However, neither Li Lingxi nor Yi Tian Zong moved a single step. Their gazes were all on the formation as though they wanted to see through it.

Inside the formation, Chen Feng's gaze was incomparably solemn. At this moment, the final moment of the spirit vein collection had arrived. Chen Feng could already feel that there was a powerful spiritual object within the depths of the spiritual vein region that was about to be sucked over by the powerful suction force from the Heavenly Pill Immortal Manor.

However, that spiritual object seemed to be extremely unwilling, and it was doing its best to resist the suction force coming from the Heavenly Pill Immortal Manor.

However, from Chen Feng's point of view, this resistance was like a battle between trapped beasts. If there were no surprises, this spiritual object would not be able to hold on for long.

Sure enough, after a short two minutes, Chen Feng suddenly heard an ear-splitting dragon roar. The next moment, a white dragon that was as thick as a wrist abruptly flew out from the depths of the Spiritual Vein.

"Haha, I'm finally out!" Chen Feng looked at the white dragon with eyes full of greed. "Since you've come out, I will absolutely not let you go back!"

"Go ahead. The Celestial Dan Immortal Estate, go all out!" Chen Feng roared in his heart, his eyes filled with madness.

"Rumble ~ ~ ~" The Heavenly Pill Immortal Manor seemed to have experienced Chen Feng's urgency and the suction force grew stronger crazily.

"Aoouuu ~ ~ ~"

All of a sudden, the White Dragon let out a loud roar, its pair of pure white dragon eyes shining with boundless unwillingness! However, the huge suction force from the Heavenly Pill Immortal Manor was like a giant hand that firmly held onto the white dragon. It sucked it into Chen Feng's dantian without any resistance and then disappeared into the Heavenly Pill Immortal Manor.

The moment the white dragon disappeared, the trembling of the mountain stopped and the entire spirit vein area lost its liveliness. The only thing left in the cave was a carpet of spirit stones.

Without a spirit vein, this place would never produce new spirit stones.

Chen Feng did not even glance at these spirit stones. His figure flashed as he too, entered the Heavenly Pill Immortal Manor.

"Aoouuu ~ ~ ~"

In the main hall of the Celestial Dan Immortal Palace, a white dragon roared violently as it soared into the skies.

Seeing Chen Feng enter, the white dragon seemed to have found the source of its hatred and suddenly pounced towards Chen Feng. Its sharp spiritual energy claws were like top-grade sharp blades as they tore towards Chen Feng.

"In the Heavenly Pill Immortal Manor, I am the heavens! Who cares if you're a dragon or a bug, just lie still! " A terrifying willpower suddenly exploded in Chen Feng's eyes.

Instantly, Bai Long's figure abruptly stopped in midair, unable to move at all!

"Now, merge with the Immortal estate and become a part of it!"

A wailing sound rang out. The White Dragon was unable to resist as Chen Feng's will grabbed onto the wall, turning it into a dragon-shaped pattern, as if it was originally engraved on the wall.
