Trading the heavens starting from immortality

The abyss beneath the earth was not completely dark; there were still faint lights emanating from individual fluorescent plants.

The most common type is a plant called "luminescent mushroom," which is similar in shape to a mushroom but much larger, with some even growing as tall as a tree.

At the eighth level of the Body Secret Realm, the Divine Might Realm, one can see in the dark as if it were daytime. At the tenth level of the Divine Power Realm, one possesses even stronger perception, able to detect any movement or spatial change within a thousand steps. Therefore, the dark world poses no threat to Fang Han whatsoever.

If one reaches the realm of supernatural powers, their perception of the physical body becomes even stronger; a sweep of magical power can completely detect objects several kilometers, or even tens of kilometers away. Therefore, those in the realm of supernatural powers can kill enemies from dozens of miles away by flying on their swords.

"The underground world is fraught with countless dangers. Numerous demons may appear at any moment to attack you. Being in constant danger will temper one's spirit, develop the brain's potential, and hone practical combat experience. Most of our Feathered Ascension Sect's true disciples cultivate underground before advancing to supernatural powers. You've only recently broken through and lack practical combat experience. Training here can help further enhance your spirit and increase your combat experience."

Fang Qingxue said.

During her time in the Divine Transformation Realm, she also frequently trained in the deep underground world.

Of course, ordinary disciples of the Divine Transformation Realm must have a magical robe and a magical flying sword to protect them if they want to enter the underground abyss world; otherwise, it is almost impossible to enter the underground world.

"Yes, Sister Qingxue."

Fang Han followed behind Fang Qingxue and said.

Besides what Fang Qingxue mentioned, the deep underground abyss also contains abundant mineral deposits, such as ten-thousand-year-old iron, black crystal, refined gold, mithril, purple silver, sea tide jade, and white obsidian steel—minerals extremely rare on the surface. These are all excellent materials for crafting magical artifacts and spiritual weapons. Some of these rare minerals can even aid in cultivation, enhancing one's spirit, and so on.

In the underground world, there are also some strange and wonderful monsters, such as the one-horned viper, the earth demon bear, the blood-mane giant lion, the abyss blood wolf, the demon elephant, and so on. The blood of these monsters is also a good material for refining some pills, and their fur and bones can be sold for a sky-high price in the secular dynasty, and are sought after by kings and nobles.

In addition to these, there are many poisonous insects, mosquitoes, scorpions, centipedes, toads, and the like.

Fang Han followed Fang Qingxue through the forest of glowing mushrooms. A blood-red figure lurked in the shadows and lunged at Fang Han as they approached. A pungent, fishy stench filled the air, and sharp, knife-like fangs were faintly visible. But in the next instant, a pink light flashed, and the blood-red figure was instantly cleaved in two, dying instantly.

This is a treacherous and cunning abyssal blood wolf, attempting to kill its prey with a single blow through disguise. Its body is as strong as a calf, and its teeth are like small knives and daggers. Even a martial arts expert at the Divine Power Realm would be bitten to death if ambushed by it. Even the subterranean demons are on its hunting list. It just so happens that it encountered the vicious Fang Han today, and its life has come to an end.

The fur of the Abyss Blood Wolf is extremely rare. Blood Wolf coats made from its fur are worth a fortune in secular dynasties and are sought after by many high-ranking officials and nobles.

"The corpse of the Abyss Blood Wolf was also a good item, what a pity!"

Looking at the blood wolf's corpse, Fang Han secretly regretted not listing it directly for sale in the trading market.

Because Fang Qingxue was around, he dared not reveal his other secrets until he had sufficient self-protection capabilities.

However, Fang Han also took out the most valuable skull from the blood wolf and put it in his pack.

The skull of the Abyss Blood Wolf, also known as the "Blood Crystal," contains extremely rich essence and can be considered a "heavenly treasure."

For ordinary people, wearing a "blood crystal" can cure physical weakness and replenish deficiencies in qi and blood. If Lin Daiyu had had the opportunity to wear one, she might not have died from physical weakness.

In addition, "blood crystals" are also good materials for refining magical artifacts, spiritual weapons, and some elixirs.

Seeing Fang Han kill the Blood Wolf with the "Crimson Desire Sword," Fang Qingxue stopped in her tracks, her beautiful brows furrowed, and said:

"Fang Han, magical treasures like spirit swords are merely external objects. If you want to reach the level of supernatural powers, you cannot rely on these. You need to rely on your own abilities. I hope you can keep this in mind."

"Yes! Sister Qingxue, I remember."

Fang Hanqian said in a humble tone.

Fang Qingxue is someone who has been through it all, so you should listen carefully to her advice.

At the very least, one should try to make a good impression on this goddess of thunder.

Thus, in the journey that followed, Fang Han displayed an extremely superb, back-to-basics swordsmanship. Each move, though seemingly ordinary, always killed the attacking monsters at the most opportune moment.

This also amazed Fang Qingxue.

Even she wouldn't dare say that she could definitely suppress this genius disciple in terms of swordsmanship alone.

The two traveled through the underground world, stopping and starting along the way. Whether it was the Abyss Blood Wolf, the Earth Demon Bear, the Three-Headed Spirit Serpent, or the Underground Demon, they all met their end under Fang Han's sword.

Through constant battles, Fang Han's combat experience steadily improved. Fang Qingxue watched Fang Han train, occasionally offering guidance on his swordplay, power generation, and techniques. Fang Han quickly grasped Fang Qingxue's meaning and applied it to his own swordplay.

And so it went, a day and a night later.

Finally, Fang Qingxue simply stopped giving him pointers. She also realized that Fang Han's swordsmanship had reached the pinnacle of the mortal realm, and even a Grandmaster at the peak of the Divine Transformation Realm would find it difficult to surpass him. The intensity of these training sessions was clearly far from sufficient.

Roar!

Just then, a fierce roar suddenly came from afar.

A group of underground demons carrying torches walked towards the direction where the two were.

These subterranean demons, wielding steel forks and torches, are far more robust than ordinary demons; they are Yakshas who have undergone a metamorphosis. Only Yakshas who have undergone this metamorphosis, reaching a level comparable to a god, can gain night vision. Otherwise, even a demon would be unable to see in pitch-black darkness.

The Yaksha was more robust than the average subterranean demon, with two large bulges on its back that were wings that were being conceived.

Only when the wings are fully formed and the ability to fly is one considered to have transformed into a Flying Yaksha, possessing combat power comparable to the tenth level of the Divine Transformation Realm of human flesh.

The Flying Yaksha takes a further step, transforming into human form and becoming an Asura comparable to a master of supernatural powers. When an Asura transforms again and completely becomes human, he is called a Great Asura, whose combat power is comparable to an elder of a high-level immortal sect.

If a Great Asura advances further and reaches the Longevity Realm, he will become the supreme leader of the underground demon race, also known as the "Demon Emperor".

The demon gods and demon emperors in the demonic path are also ancient giants of the Longevity Secret Realm.

The group of monsters approaching Fang Han and Fang Qingxue consisted of twelve Yakshas, ​​and they were on patrol.

Their ranks were orderly, resembling an army of subterranean demons, clearly an elite force used by the higher-ups of the demonic path to attack the human world.

"It seems we're not too far from the Demon God's Altar. Fang Han, you train nearby while I go and destroy the Demon God's Altar."

Fang Qingxue said, glancing at Fang Han with her beautiful eyes, before disappearing without a trace, using some unknown method.
