Ghost Immortal

The temperature of Yin Fire is not that of an ordinary flame; it is formed from the condensed corpse energy of a zombie over hundreds of years, and it burns Yin energy rather than Yang fire.

The spiritual energy defense wasn't very effective, and large beads of sweat quickly appeared on Li Feng's forehead.

The jade box in his arms froze instantly.

Li Feng looked down and saw that the sealing talisman on the jade box was twisted and deformed under the frozen gas, and the light of the runes on the inside of the lid was getting dimmer and dimmer.

The coffin fungus was restless inside the jade box. Its blood-red cap had thawed under the ice, oozing dark red liquid.

The juice seeped through the cracks in the jade box and dripped onto Li Feng's chest.

He felt as if scalding liquid nitrogen had been poured over his chest, and his skin was instantly frozen by the liquid.

Strangely, the freezing sensation lasted only a moment before transforming into an extremely yin and cold airflow that traveled along the meridians in the chest and into the dantian.

This is the origin of the coffin fungus, the essence of the female zombie king's hundreds of years of cultivation.

A sudden inspiration struck Li Feng.

Theoretically speaking, this thing is also a type of living organism.

Perhaps this cauldron can also refine coffin fungi and nourish itself in return.

The small cauldron is an alchemy furnace, and the zombie king spews out yin fire.

The current situation perfectly meets all the conditions for refining coffin bacteria.

Li Feng gritted his teeth, sat cross-legged, and fully opened the jade box.

Once the jade box was opened, the coffin fungus was completely exposed to the smoldering fire.

The palm-sized cap quickly burst open, turning into a fist-sized amount of blood-red liquid.

The liquid floated in the air, emitting a strong aura of yin energy, and the entire interior of the small cauldron was reflected in a blood-red color.

At the same time, he took out the Nourishing Spirit Pill from his pocket and swallowed it along with the pill, for double protection.

The Nourishing Spirit Pill melts upon entering the mouth, transforming into a gentle stream of spiritual energy that flows into the dantian.

The energy vortex in his dantian, which was originally only the size of a grain of rice, grew larger under the stimulation of the Nourishing Spirit Pill.

Taking advantage of the opportunity, Li Feng guided the blood-red liquid transformed from the coffin fungus along his meridians to his dantian.

The moment the yin energy entered his dantian, Li Feng felt as if he were stuffing his stomach with ten-thousand-year-old ice.

An extremely yin and cold aura exploded in the dantian, violently colliding with the original spiritual energy in the dantian.

Two completely opposite forces were tearing each other apart in the dantian, and the meridians were impacted as if they were being pierced by countless steel needles at the same time.

Li Feng's lips instantly turned blue, white frost formed on his skin, and even his hair and eyebrows were frozen stiff.

But since he was a sports student in his previous life, he gritted his teeth and persevered.

The talent of having a nine-inch spiritual root was revealed at this moment.

An ordinary cultivator's spiritual root cannot withstand this level of Yin energy impact; their meridians would be directly frozen and shattered.

However, the meridians of a nine-inch spiritual root are far more resilient than those of ordinary people. Despite the violent yin energy, it is always firmly locked within the meridians and cannot leak out even a fraction.

Li Feng circulated the Maoshan Qi Cultivation Technique, using the original spiritual power in his dantian as a guide to refine and absorb the yin energy bit by bit.

This process was extremely slow. Yin energy merged into spiritual power, accompanied by intense stinging pain, but his dantian was rapidly expanding.

A cyclone the size of a grain of rice can instantly grow to the size of a soybean.

Soybeans grow into broad beans, and broad beans grow into pigeon pebbles.

The last of the crimson liquid was refined, and Li Feng's dantian had expanded to the size of an egg.

The spiritual energy in the dantian condensed from a gaseous state into a liquid state, forming a pool of pale golden spiritual liquid at the bottom of the dantian.

This is a sign of the Qi Refining Period!

But Li Feng's changes go far beyond that.

As his dantian expanded, extremely pure yin energy surged straight up his spine, crashing into his spiritual root.

The spiritual root is located within a cultivator's spine and serves as a bridge connecting the spiritual energy of heaven and earth. The longer and thicker the spiritual root, the higher the cultivation talent.

Li Feng's spiritual root had already reached nine inches, just one step away from the legendary ten-inch top-grade spiritual root.

At this moment, under the impact of the coffin fungus's origin, the bone wall at the end of the spiritual root shattered.

New spiritual root tissues grew out of the cracks, extending upwards inch by inch.

The pain of breaking through the spiritual root is more intense than that of expanding the dantian.

The spine felt as if it had been split open segment by segment, and the bone marrow had been frozen into ice blocks, which were then melted by fire.

Li Feng gritted his teeth, his mouth filled with the taste of blood.

After an unknown amount of time, the tip of the spiritual root finally stopped growing.

Li Feng took a look using his internal vision technique and was immediately pleasantly surprised.

The end of the nine-inch spiritual root extended by a full inch.

This is a ten-inch spiritual root!

A legendary, top-grade spiritual root!

Moreover, his cultivation level also broke through, leaping directly from the Spirit Root stage to the Qi Refining stage.

"The Netherworld Spiritual Root, ten inches is the most precious."

"Those with ten inches of spiritual root can connect the Yin and Yang realms. Using the spiritual root as a guide, ghost fire in the netherworld will naturally arise."

A vast, unfathomable voice suddenly echoed in Li Feng's mind.

The cultivation method for Netherworld Ghost Fire automatically appeared in his mind.

Ghost fire is not the flame of the living world, but the ghost fire of the underworld.

It does not require spiritual power to drive it, nor does it need talismans to guide it. It only needs to use its spiritual roots to communicate with the gap between the Yin and Yang realms to bring the ghost fire of the Yin realm to the Yang realm for its own use.

This power far surpasses the spiritual power of ordinary cultivators.

Li Feng opened his eyes and found that the Zombie King was still using Yin Fire to burn the cauldron.

The cauldron was heated until it turned bright red, and the runes on its walls glowed with a dark golden light under the high temperature.

But the Zombie King didn't seem to have any intention of stopping. He was convinced that the coffin fungus was inside the cauldron and wouldn't give up until he burned the cauldron through.

This is truly a blessing in disguise!

Li Feng sat cross-legged in the cauldron and began to cultivate according to the methods of the Netherworld Ghost Fire in his mind.

At the tip of the ten-inch spiritual root, a faint green light shone.

The Netherworld Fire has been successfully forged.

As soon as this flame appeared, the Zombie King's Yin Fire instantly withered, like a mouse seeing a cat.

The dark red ghost fire trembled before the eerie green ghost fire, retreating and shrinking back into the zombie king's corpse core, never daring to emerge again.

The Zombie King staggered back three steps, the dark red ghost fire in its eye sockets flickering violently, and a look of fear appeared on its face.

Ghost fire is the nemesis of all yin fires, because it is the primordial fire from the depths of the underworld, the fire of punishment in the underworld.

In the underworld, only the Emperor can use Netherworld Ghost Fire to punish evil spirits. The Yin Fire of zombies is utterly insignificant compared to Netherworld Ghost Fire; it shatters at the slightest touch.

Li Feng manipulated the Netherworld Ghost Fire, which floated out of the small cauldron and hovered in mid-air.

Under the moonlight, eerie green will-o'-the-wisps burned, and a hideous ghost face could be vaguely seen in the center of the flames.

The ghost's mouth opened and closed, emitting a low whimper.

The Zombie King took three steps back.

The female zombie king also floated over. She looked at the eerie green will-o'-the-wisp with the same apprehension, but her eyes also revealed a longing.

Half of her corpse core was absorbed by the coffin fungus, severely damaging her cultivation.

If one can absorb the primordial yin energy within this ghostly flame, perhaps one can recover some of their strength.

But she didn't dare to get close.

The ghost fire is too effective against zombies. If you get within three feet of them, their corpse energy will be ignited by the ghost fire, burning them to ashes.

At this moment, Li Feng stood up from the cauldron, reached out and grasped the Netherworld Ghost Fire, and smiled slightly at the Zombie King.

"Thank you for using your Yin Fire to help me refine the coffin fungus. I will remember this favor."

The Zombie King hadn't expected the human to suddenly become so strong.

He used yin fire to burn the cauldron, intending to force out the coffin fungus and, incidentally, roast the person inside to death.

Instead of forcing out the coffin fungus, it helped others refine the essence of the coffin fungus, greatly improving their cultivation and even obtaining the Netherworld Ghost Fire, which is specifically designed to suppress zombies.

This is a complete loss, like losing both your wife and your army.

Li Feng gave him no chance to react and pointed the Netherworld Ghost Fire towards the Zombie King.

The eerie green flames transformed into a beam of green light, shooting straight at the Zombie King's chest.

The Zombie King dared not take the attack head-on, and with a sway of its body, it dodged the direct shot of the ghost fire.

But the will-o'-the-wisp exploded beside him, turning into countless tiny sparks that splashed onto his black robe.

The black robe was burned with countless small holes by the sparks, revealing the dark blue scales underneath.

The scales hissed and emitted foul-smelling black smoke as they were scorched by the ghostly flames.

"roar!!"

The Zombie King roared in pain and retreated rapidly to the entrance of the shrine.

The female zombie king dared not approach Li Feng again. She floated back above the coffin and used the last remaining blood-red corpse energy to protect it.

Its blood-red eyes were fixed on Li Feng, and a low whimper came from its throat, like a kitten hissing.

Li Feng did not continue the pursuit.

He had just broken through to the Qi Refining stage, and even though he had awakened the Netherworld Ghost Fire, his cultivation was not yet consolidated, and his spiritual energy consumption was also very high.

While ghostly flames can suppress zombies, their power is limited when the difference in strength is too great.

If the Zombie King is truly pushed to the brink and fights desperately, the outcome is uncertain.

Moreover, his purpose for this trip was coffin fungus, which he has now obtained, so there is no need to create unnecessary complications.

Li Feng put away the Netherworld Ghost Fire, shrunk the small cauldron, and put it back in his arms.

He turned and walked out of the ancestral hall, heading towards the outskirts of Tengteng Town.
