As soon as Hua Guangyuan died, Yang Feng put Hua Guangyuan and the others' space equipment and spiritual weapons into the Cave Heaven World, and then disappeared in place with a flash, speeding away into the distance.

In a corner of the area where the water realm monsters were located, Yang Feng put dozens of water crystal nuclei left behind after the death of the realm monsters into the cave world, and in a flash, they entered the cave world, and the cave world was illusionized as a drop of water and merged into the water.

After entering the water, Yang Feng glanced at the water crystal nuclei sprinkled in the cave world, a faint smile flashed in his eyes, and he began to operate the Black Emperor Water Emperor Fist, absorbing the pure water system vitality in the water crystal nucleus, and transforming it into pure water system mana.

With the passage of time, under the supply of a large amount of water system crystal nuclei and pure water system vitality, Yang Feng's Black Emperor Water Emperor Fist progressed rapidly, quickly reaching the realm of Dacheng, and under Yang Feng's operation, the magic spell of the Black Emperor Water Emperor Fist was condensed.

After condensing the magic spell of the Black Emperor Water Emperor Fist, Yang Feng did not hesitate or hesitate at all, and continued to operate the Black Emperor Water Emperor Fist, absorbing the water crystal nuclei stored in the cave world, and all of them were converted into pure water mana, and his strength and combat power increased dramatically.

When the water crystal nucleus in the Cave Heaven World was exhausted, Yang Feng moved, came out of the Cave Heaven World, returned to the water, and sped away into the distance.

"Let's use you to test the power of the Black Emperor Water Emperor Fist!"

Looking at the hundreds of Returning to the One Realm monsters pouring in from all directions, Yang Feng's eyes flashed with anticipation, and with a light snort, the water mana in his body surged, and the Black Emperor Water Emperor Fist unfolded, one by one, fist shadows containing the magic spell of the Black Emperor Water Emperor Fist poured out from Yang Feng's fist, and with terrifying power, they bombarded the hundreds of One Realm monsters in all directions.

Rumble! Rumble! Rumble!

With the sound of violent explosions, the monsters of the One Realm were hit by terrifying fist shadows, exploded, and turned into fragments in the sky, revealing crystal nuclei of the crystal system of the water system, exuding a faint light.

In a matter of moments, hundreds of Guiyi Realm monsters were bombarded by Yang Feng using the magic spell of the Black Emperor Water Emperor Fist, which made Yang Feng's face show a satisfied smile, and with a wave of his big hand, he collected hundreds of water crystal nuclei into the Cave Heaven World, and turned into an afterimage, speeding away towards the distant waters, continuing to be familiar with the magical powers of the Black Emperor Water Emperor Fist, and hunting a large number of Guiyi Realm monsters.

When Yang Feng's Cave World stored thousands of crystal nuclei of the Returning Realm monsters, he did not continue to hunt monsters, but left the water area and went to the Fire Domain.

The Fire Domain is a world of flames, completely enveloped in flames, and the scorching flames release a scorching and irritable aura, and those who are not cultivated enough will soon be burned to ashes when they step into it.

In the endless world of flames, fire wolves, fire dragons, fire cows, fire pigs, fire snakes, fire dragons and other flame monsters condensed by the power of flames roam freely in the world of flames, and constantly fight each other, devouring each other's water crystal nuclei, strengthening their own bodies, and turning into food for evolution.

Yang Feng stood in front of the Fire Domain and took a look, then his body moved, and he entered the Fire Domain, and one after another scorching flames swept towards Yang Feng's body, wanting to burn Yang Feng to ashes.

In the face of the scorching flames, Yang Feng's expression remained unchanged, and the Red Emperor Fire Emperor Qi unleashed, and the flames close to Yang Feng were instantly inhaled into Yang Feng's body, transforming into pure fire mana.

It's just that the fire system energy contained in the flames is too little, and the transformed fire system mana is too small, and it is a little complicated, which makes Yang Feng frown slightly, so he completely refines it, expelling the impurities in it, and then only exerts the Red Emperor Fire Emperor Qi, and arranges a red protective shield outside the body to block the invasion of the flames, and does not absorb the fire system vitality in the flames.

After doing all this, Yang Feng's body moved, turned into a fiery red figure, and galloped towards the depths of the fire domain.

In the process of galloping, one by one the fire monsters of the True Qi Realm, the True Yuan Realm, the Gang Qi Realm, the Yin-Yang Mirror, and the Heavenly and Human Realm constantly attacked Yang Feng, but they were all killed by Yang Feng casually, turning into a fire crystal nucleus, which was absorbed by Yang Feng and transformed into pure fire mana, strengthening the Red Emperor's Fire Emperor Qi.

Soon, Yang Feng entered the depths of the Fire Domain, and one by one, the fire crows condensed by the power of the flames appeared on Yang Feng's side, exuding the powerful aura of a Unified Realm martial artist.

The size of the fire crow was not large, only more than a zhang, and its body was shrouded in flames, a blood-red color, releasing a scorching breath.

There were too many fire crows, there were thousands, forming a sea of red, surrounding Yang Feng, letting out excited roars, turning into red afterimages, waving red claws, and speeding straight towards Yang Feng's side.

"Black Emperor Water Emperor Fist!"

In the face of the attack of thousands of fire crows, Yang Feng's expression remained unchanged, the water mana in his body surged, and the magic spell of the Black Emperor Water Emperor Fist was unleashed, and the fist shadows containing the mysteries of the magic power appeared from Yang Feng's body, with terrifying power, lightning to meet one fire crow after another, colliding with them.

Rumble! Rumble! Rumble!

In the violent explosions, the terrifying fist shadows and the fire crows collided together, and the fire crows were blasted by the terrifying fist shadows, turning into countless flame fragments, and integrating into the flame world, leaving behind fire crystal nuclei that emitted fire, suspended in the flame world.

In a matter of moments, thousands of fire crows were killed by Yang Feng, and thousands of fire crystal nuclei were included in the cave world by Yang Feng, and then a figure disappeared in place and galloped away into the distance.

Three days later, after Yang Feng hunted and killed tens of thousands of Unified Realm Flame Monsters, he was no longer hunting flame monsters, but entered the Cave Heaven World, absorbing the pure fire system vitality contained in tens of thousands of fire crystal nuclei, transforming it into pure fire mana, strengthening the Red Emperor Fire Emperor Qi, cultivating it to the realm of Dacheng, and successfully condensing the magic spell of the Red Emperor Fire Emperor Qi.

After condensing the magic spell of the Red Emperor's Fire Emperor Qi, Yang Feng did not stop, but continued to absorb the pure fire energy contained in the fire crystal nucleus, transforming it into mana, strengthening the Red Emperor's Fire Emperor Qi's divine power, and enhancing his own strength and combat effectiveness.

After the fire crystal nuclei in the cave world were absorbed by Yang Feng, Yang Feng came out of the cave world and continued to hunt the flame monsters of the Guiyi realm, storing thousands of fire crystal nuclei in the cave world before leaving the fire domain and speeding towards the place where the earth domain was located.

The earth area is a rocky mountain range full of dry atmosphere, and the eyes are full of undulating, bare rock peaks without a trace of green, countless monsters condensed from rocks, walking among the rock peaks, countless warriors from all over the world, fighting rock monsters in the rock peaks, hunting rock monsters, and obtaining the crystal nucleus of the earth system.

After coming to the Earth Domain, Yang Feng did not hesitate or hesitate at all, and immediately turned into an afterimage and galloped towards the depths of the Earth Domain.

Soon, Yang Feng crossed the area where the True Qi Realm, the True Yuan Realm, the Gang Qi Realm, the Yin-Yang Mirror, and the Rock Monsters of the Heavenly and Human Realms were located, and came to the Unified Realm Rock Monster Area where the Earth System Vitality was extremely strong.

"Kill!"

Feeling the huge aura in Yang Feng's body, the leader of the rock giant roared angrily, holding a three-zhang long rock stick, and took the lead in rushing towards Yang Feng's side, and the three-zhang long rock stick, with terrifying power, smashed towards Yang Feng's body, looking like he wanted to smash Yang Feng into meat sauce.

At the same time, hundreds of Returning Realm Rock Giants also roared angrily, following closely behind the leader of the Rock Giants, holding rock sticks one after another, and approaching Yang Feng's side.

"Red Emperor Fire Emperor Qi!"

In the face of the attacks of hundreds of Returning Realm Rock Giants, Yang Feng's expression remained unchanged, and with a light shout, the fire mana in his body surged, and the Red Emperor Fire Emperor's divine power spell operated, and one after another scorching flame sword qi emerged from his body, with a scorching sharp edge, slashing towards the bodies of one Returning Realm Rock Giants one by one.

Bang! Bang! Bang!

In the crisp sound of metal collision, the scorching flame sword qi, with the scorching sharp edge, slashed down on the bodies of the rock giants of the One Realm, turning into scorching flames, enveloping the rock giants of the One Realm and burning them to ashes, leaving behind one after another earth-yellow crystal nuclei, exuding a thick earth system vitality.

In a matter of moments, hundreds of Unified Realm Rock Giants were slaughtered by Yang Feng using the Red Emperor Fire Emperor Qi, and hundreds of earth-based crystal nuclei were included in the Cave Heaven World by Yang Feng.

Subsequently, Yang Feng continued to wander around the area where the monsters of the Returning Realm were located, constantly hunting and killing the rock monsters of the Returning Realm one by one, and obtaining the Earth Crystal Nuclei containing a large amount of Earth Vitality.

Three days later, Yang Feng hunted tens of thousands of Returning Realm monsters, his body moved, entered the Cave Heaven World, and began to operate the Emperor's Earth Ecliptic, absorbing the pure Earth System Yuan Qi contained in the Earth Crystal Nucleus, transforming it into pure Earth System Mana, and strengthening the Emperor Earth Ecliptic.

With the passage of time, Yang Feng cultivated the Emperor Earth Yellow Dao to the realm of Dacheng with the help of a large amount of Earth Crystal Nucleus Supply of the huge Earth System Yuan Qi, and condensed the Emperor Earth Emperor Dao's Divine Power Spell in his body.
