Alien Science Cultivation

A moment later... the turbulent flow of Guixu Qi arrived as expected, and the aura on Chen Ying's body gradually weakened a lot, "This really happened... Hehe... My golden elixir is really gone, and my realm has regressed to the perfect foundation..." Chen Ying said happily instead of being angry.

"...20 meters... The Nirvana Layer appears and begins to jump..."

……

“…30 meters, the dense layer of Guixu Qi, should we start energy exchange?…” The voice of the golden finger continued to ring.

"Wait...what does energy replacement... mean?" Zhang Qiang asked puzzledly.

"Literally...haha...you don't just not understand, you just can't believe it, right? Let me show you the methods of a level 7 technological civilization..."

As Chen Ying spoke, he took out a top-grade spirit stone. A golden light shot out from his golden finger and enveloped the spirit stone. After a moment, the spirit stone dimmed and slowly became darker and darker... until it stabilized.

"Let's see... Generally, everything has two sides. If there's a Spirit Stone, there's a Guixu Stone... But this exchange process consumes a lot of energy. Top-grade Spirit Stones can only be exchanged for high-grade Guixu Stone..."

"Guixu Stone..." Zhang Qiang took the Guixu Stone and felt the Guixu Qi inside. It was basically the same as the spiritual energy content in high-level spiritual stones. This gave Zhang Qiang a bold idea...

"I want to exchange it for 10,000 yuan... Is that feasible...?"

"Why do you need so many Guixu Stones?... Could it be... when you were at Shadow Peak..." Chen Ying guessed.

"Yes... spiritual energy can be used for cultivation, and so can Guixu Qi... cultivators can control spiritual energy to 'devour' Guixu Qi. Hmm... the record says it's devoured... but it's actually a kind of neutralization phenomenon... During the neutralization process, a force called the power of annihilation will appear... It can strengthen the dantian, meridians, physical body, etc..." Zhang Qiang explained. It was only then that Zhang Qiang understood the difference between the power of annihilation and the power of nothingness...

Before Zhang Qiang could think, Chen Ying's voice rang out in his mind again, "I see... it's possible... it just takes time..."

"It's okay... We have plenty of time..." Zhang Qiang responded, and with a movement of his spiritual sense, a circular cave appeared on the stone wall above the underground river. Zhang Qiang and Chen Ying entered one after another. A silkworm shell covered the two of them. The porcelain clothes blocked the ghost's spiritual sense, and the silkworm shell blocked the spiritual sense of strange beasts and cultivators. The entrance to the cave was also restored to its original state by Zhang Qiang. The two of them were hidden quite well.

An hour passed quietly, and Zhang Qiang obtained 10,000 high-level Guixu stones as he had hoped, and Chen Ying also successfully exchanged for more than 1,000. Although she still had doubts about whether the Guixu Qi was as magical as Zhang Qiang said, she firmly believed that Zhang Qiang would not deceive her.

A moment later, the metal moth continued its steady descent. "30 meters, quantum communication activated... Ground detected... Stealth and slow progress... Moving object detected..."

"There really are ghosts..." Zhang Qiang and Chen Ying stared intently at the image displayed on the golden finger, stunned and incredulous. The space in the image was dark and gloomy, with shadows densely shrouding the cave entrance. These shadows sat quietly and cross-legged nearby, absorbing the rich Guixu aura. From the image, it could be roughly inferred that most of these shadows possessed cultivation levels at the Tribulation Crossing Realm. While the image couldn't capture the specific aura of the scattered shadows in the distance, this information was enough to confirm the existence of the underworld and the truth behind the legendary evil spirits.

Chen Ying attempted to control the metal moth to get closer, hoping to see the details of the evil spirits, but Zhang Qiang quickly dissuaded her. After all, they had no plans to go down yet, and leaving the metal moth behind would surely be of great use in the future.

"At 10 meters, there is a turbulent flow of Guixu Qi... At 20 meters, there is the Nirvana Layer, which should be caused by the mutual exchange and impact of spiritual energy and Guixu Qi. However, this Nirvana Layer, caused by the impact of a large amount of Guixu Qi and spiritual energy, is far more powerful than the Nirvana force generated by ordinary cultivators controlling spiritual energy and "swallowing" Guixu Qi. However, this phenomenon is not actually a swallowing phenomenon, but a positive and negative combination, just like the discharge generated by the combination of positive and negative charges. Similarly, the combination of spiritual energy and Guixu Qi will also produce a force, which is the power of Nirvana. Dulong has always been wrong. The power of Nirvana is fundamentally different from my power of nothingness. The "swallowing" Dulong said is just the neutralization phenomenon of spiritual energy and Guixu Qi. If it weren't for my personal experience and the reminder of this metal moth, I would probably think it was swallowing like Dulong... It also solved the confusion in my heart. Dulong, Ni Fang, the cultivators at the entrance of hell, the ghost body, etc., the power of nothingness they mentioned are all the power of Nirvana. I was also confused for a while. Why is the "force of nothingness" different from his own? It turns out they're not the same force at all. After passing the Nirvana Layer, the Guixu Qi is at its densest. Once reaching the surface, the concentration of Guixu Qi gradually dilutes. It seems that to go deeper underground, one must first withstand the turbulent layer. What level of cultivation is needed to withstand it? Or perhaps possessing the ability to travel across time would also be sufficient. If Dulong were here, perhaps they could give it a try. This Nirvana Layer doesn't appear insurmountable. With powerful spatial transmigration abilities, or powerful magical powers or physical bodies, one could easily cross the two realms. However, for an ordinary cultivator, their spiritual power would be completely suppressed, undoubtedly resulting in their certain death. This explains why no cultivators are willing to enter, and similarly, evil spirits are reluctant to enter. However, once the black gold has grown and matured, perhaps a try is possible. "The immediate priorities are to cultivate the Tribulation Crossing and refine the Burning Heaven Leaf..." Zhang Qiang pondered for a long time before Chen Chenying's voice brought him back to reality.

"What should we do now?...The mechanical moths have been placed..." Chen Ying couldn't help but ask as she looked at Zhang Qiang who was lost in thought.

"Practice... then overcome the tribulation... practice some more... then overcome the tribulation... If it's really possible... I'll open a passage up there to see what's going on. It would be best if I could overcome the tribulation nearby... Don't come out..." Zhang Qiang instructed, and with a flick of his spiritual sense, a passage slowly formed leading to the surface. Then, Zhang Qiang silently passed through the passage, approaching the surface. A quarter of an hour later, a herd of over a hundred Chaos Thunder Pigs appeared in Zhang Qiang's consciousness. "Sorry... can you lend me your space..." Zhang Qiang muttered happily to himself. Chaos Thunder Pigs resemble wild boars on Earth, except they have longer tusks, between which the force of lightning surges, and their fur is as strong as iron. Their primary lethality lies in the penetrating power of their tusks and the damage caused by lightning. Of these over a hundred Chaos Thunder Pigs, over fifty possess the strength of the late stage of the Questioning Nirvana Realm, and over twenty are at the early stage of the Questioning Ding Realm. If Zhang Qiang hadn't achieved a breakthrough in the Six Paths of Reincarnation through his third dantian, he would likely have no choice but to turn and flee. But now, he couldn't help but take action, because the Burning Heaven Bamboo Leaf in his Dantian was already impatient. Zhang Qiang also wanted to see how powerful this small bamboo leaf was. "Hold it for me..." As Zhang Qiang's voice fell, more than a hundred hybrid electric pigs froze. A dark bamboo leaf instantly pierced through the heads of all the hybrid electric pigs, and before the hybrid electric pigs' souls even reacted, they were already dead. Zhang Qiang was also stunned. He had planned to use his spiritual sense to control the bamboo leaves to defeat the hybrid electric pigs one by one, but in the end, let alone control the bamboo leaves, the moment the bamboo leaves started to move, his spiritual sense could not even detect the shadow of the bamboo leaves.
