141: Chapter 141 Underground Cultivation

The Spotted Leopard sneered, "A mere Earth Escape technique? Watch this!"

With a thought, endless fire-attribute spiritual energy converged, and a burst of true fire spewed from its mouth. In an instant, the ground before it was scorched into a lake of magma. In a sea of magma spanning over a thousand meters, that kid's Earth Escape technique would surely be unable to survive.

However, its spiritual energy did not detect Zhao Feng. The Spotted Leopard flashed, arriving a thousand meters underground within the magma. Manic fire-attribute spiritual energy surged, forcefully piercing through the surface and connecting to the magma on the planet's crust.

"Boom!" Under the pressure, the magma from the planet's core erupted violently. A full-force strike from a Cultivator at the Nascent Soul Stage had actually caused such a terrifying consequence; it was truly horrifying!

Yet, there was still no sign of Zhao Feng!

The Spotted Leopard exhausted its demonic power, leaving the underground in a mess, but in the end, it had to retreat helplessly.

Where had Zhao Feng gone? He had long since used terrain modification and the Mountain God's ability to run far away.

Of course, he couldn't go to the surface for now; he had to strive for a Breakthrough to the Nascent Soul Stage first!

In fact, such an elevation for Zhao Feng was completely impossible for ordinary people. To increase the capacity of spiritual energy, refining it wasn't enough. Powerful spiritual energy required a formidable body and spirit to ensure one wouldn't be blown apart. Zhao Feng possessed a formidable Steel Body and spirit; the capacity of his Steel Body even exceeded the Nascent Soul Stage.

Although his Mental Energy had improved due to brain enhancement, it had not yet exceeded the level of the Nascent Soul Stage. One reason for hiding and Cultivating this time was the need to improve his Mental Energy.

Without further ado, Zhao Feng used his terrain modification ability to build a small stone chamber underground. He didn't need oxygen now, so a stone chamber to shelter in was sufficient.

With a thought, he entered the Immortal Cave.

Inside the Immortal Cave, an extremely anxious Liu Xuan paced back and forth, filled with fear. Seeing Zhao Feng suddenly appear, she let out a cry of surprise and hugged him tightly, refusing to let go.

"Benefactor, Benefactor, you finally appeared! Thank heavens, are you okay? What about that leopard? Did it chase after you?" Liu Xuan blurted out a string of questions, her mind deeply agitated.

"It's okay, it's okay!" Zhao Feng comforted her gently. After she calmed down, he told her everything—except, of course, about the System. This was his secret for survival; telling Liu Xuan would only harm her.

"Benefactor, since this Immortal Cave is so amazing, we must Cultivate well and then go make trouble for that dead leopard." Liu Xuan frowned her cute brows and said aggressively.

"Hmm." Zhao Feng nodded. This Immortal Cave was exactly the same as reality, and Liu Xuan could actually breathe here. The System was truly amazing!

During their rest, Zhao Feng explained several problems Liu Xuan had encountered during her Cultivation. Seeing that she was fine, they each began to Cultivate.

Zhao Feng silently recited to begin meditating. His physical body in the outside world, under the control of the System, automatically sat cross-legged, formed the Taiji seal, and began to Cultivate.

Because his spiritual energy had reached its limit, meditation could not increase it further. Only his Buddha Power and Divine Power were slowly increasing. The increase in Divine Power could slightly improve his Mental Energy, and Buddha Power could improve his Physique. Zhao Feng planned to Cultivate them both to their limits before doing anything else.

Days passed like this, and he didn't know how many had gone by. Finally, one day, Zhao Feng woke from meditation. By this time, his Buddha Power had reached the upper limit of one thousand, and after his Divine Power reached three thousand, it could no longer be increased. He surmised that the Power Of Faith provided by the two planets could only reach this height.

Next, it was time to continue strengthening his body.

After reaching the Golden Core Stage, his Mental Energy began to transform into higher-quality spiritual sense. Naturally, the mental microscope utilized by his Mental Energy could also see smaller things.

Those were cells.

Cell membranes, cytoplasm, nuclei, mitochondria, and other things that could previously only be seen with a microscope could now be freely manipulated and observed by Zhao Feng.

What made Zhao Feng different from ordinary people lay within his cells. Due to his Steel Body, his cell membranes and cytoplasm could weakly absorb solar energy, and the mitochondria were the core for storing that solar energy.

After the Heavenly Tribulation, this Physique changed. They had actually developed the function of storing lightning-attribute spiritual energy. This was perhaps due to the Heavenly Thunder, and also because Zhao Feng possessed a Lightning Spiritual Root. The combination of these two had formed the miracle he saw today.

There were too many substances in the cells that Zhao Feng's spiritual sense instinctively loathed; these were the things that needed to be cleaned. Under the spiritual microscope, his spiritual energy began to wash over them again and again.

Whenever his spiritual sense was exhausted, Zhao Feng would recover and then continue.

Unknowingly, several more days passed.

When the final brain enhancement was completed, Zhao Feng's spiritual sense jolted and instantly became more than ten times stronger. At this point, Zhao Feng knew that the Impurities in his body had basically been cleared. Any future improvements would require other fortuitous encounters. The improvement of his body also brought his Steel Body to a stronger state, which Zhao Feng named Bronze Body.

Future Cultivation might not be entirely by the book, but it would not have the rapid improvements he had now.

The advancement to Nascent Soul would inevitably attract lightning tribulation. Zhao Feng did not want to go out yet, so he suppressed the spiritual energy around his body and turned to study Artifact Refining.

Alchemy and Artifact Refining were not as difficult as before. After selecting Alchemy and Artifact Refining, with the help of the System, Zhao Feng could actually begin Alchemy and Artifact Refining simultaneously, and his mind felt no pressure at all. It was truly wonderful.

Of course, the specific insights still needed to be completed by Zhao Feng; the System did not have the ability to instill them.

After Alchemy and Artifact Refining time and time again, all the Materials in his pack had been exhausted, and a large pile of Spiritual Artifacts and Spirit Pills appeared before him.

Opening his eyes again, Zhao Feng knew it was time to come out of seclusion.

Liu Xuan had already reached the Foundation Establishment Middle Stage; her Cultivation speed was very fast, after all, she did not enjoy Zhao Feng's Cultivation bonus. Zhao Feng handed her the Spiritual Artifact he had prepared for her, and then the two of them put on a full set of Spiritual Artifacts; they were truly imposing and noble.

After going out, he would be Undergoing Tribulation. Zhao Feng continued to keep Liu Xuan in the Immortal Cave, flashed his figure, and arrived at the surface.

This place was far from where the previous battle took place; the Blood Fortress was completely invisible. Sweeping with his spiritual sense, the vicinity was desolate, and there were no living creatures.

Although it was night, Zhao Feng still flew straight up. After breaking through a layer of restraint, he finally arrived in space.

In space, there was eternal darkness, with only the moon accompanying Yaoling Planet reflecting the sun's rays, emitting a brilliant silver light.

Looking into the extreme distance, Zhao Feng could still see a few planets belonging to the same star System as Yaoling Planet. Those planets were very far away and appeared to have no life.

Zhao Feng's goal was the sun; his Bronze Body required massive amounts of solar radiation. Thus, he flew towards the other side of the planet.
