Looking at the great battle before him, Ye Feng quickly figured out the cause and effect.

It must have been during the time he entered the Earth Elemental Vein to comprehend the Earth Elemental True Qi that, for some reason, the Void Stone combined with the Interdimensional Teleportation Array. As a result, the Interdimensional Teleportation Array was activated, connecting the Five Elements World with the Heavenly Demon World, which led to the large-scale invasion by the demon race of the Heavenly Demon World.

Just as Ye Feng had this thought, he heard a cry of surprise.

"Lingxuan, watch out!"

That's Sun Muqing's voice!

Ye Feng turned his head and saw that Sun Muqing and Jiang Lingxuan were also fighting against the demons in the battlefield.

However, the two women deliberately suppressed their strength, only displaying the power of the Separation and Union Realm, without revealing their true combat power at the ninth level of the True Essence Realm.

At this moment, Jiang Lingxuan, who was fighting a strange-looking demon with four arms, was ambushed by another demon!

Although Jiang Lingxuan should be fine given her strength, Sun Muqing still shouted loudly to warn her!

Seeing this, Ye Feng did not hesitate at all and immediately took a step forward.

Night Wind's figure flickered, arriving in front of Jiang Lingxuan at the same time that the demon race had reached behind her.

Ye Feng raised his right hand and pointed out, unleashing the Void Yuan Divine Finger.

The demon's head was blown apart by the night wind, purple blood and milky brain matter flying everywhere, staining the surrounding ground a deep purple!

"Night wind!"

Jiang Lingxuan let out a joyful shout.

Sun Muqing also noticed Ye Feng's appearance. She immediately dealt with one of the demons and flew towards Ye Feng.

"What's going on?" Ye Feng casually killed another demon.

Now is not the time for idle chatter. Sun Muqing said succinctly, "Ye Feng, not long after you went to Black Earth Sacred Mountain, some demons secretly infiltrated the Sacred Palace, stole the Void Stone from the treasure vault, and activated the interdimensional teleportation array. That's why the demons of the Heavenly Demon World launched a large-scale invasion and attacked the Underworld Sect."

The night wind suddenly realized.

"It seems that the demon race that entered the Five Elements World through the interdimensional teleportation array was not only the one that colluded with Lena of the Blackwater Tribe," Ye Feng said.

Jiang Lingxuan added, "There are currently about 100,000 demons who have entered the Five Elements World. There are three leading demons, all of whom are at the Saint Realm. They are the Great Sage of Tianshan, the Great Sage of Chiyan, and the Great Sage of Xuanbing."

"The Netherworld Sect has requested assistance from the Heavenly Fire Sect and the Spirit Water Sect. Both sects have already arrived to provide aid. Xia Lie, the sect leader of the Heavenly Fire Sect, and Nan Lingrong, the sect leader of the Spirit Water Sect, are currently fighting against the three Great Saints of the Demon Race together with Shi Ji, the sect leader of the Netherworld Sect."

Night Breeze nodded and said, "I understand. I'll go help them now."

"If you go to help, won't your true strength be exposed?" Jiang Lingxuan said.

“That’s true, but I no longer need to hide my strength,” Ye Feng said with a smile.

Ye Feng concealed his strength and infiltrated the Underworld Sect in order to obtain the Underworld Sect's fundamental law, the Emperor Empress Earth Technique, and thus comprehend the Five Elements True Qi.

However, the night wind entered the Black Earth Sacred Mountain and perfected its understanding of the Earth Element True Qi within the Earth Element Spiritual Vein.

In this way, Ye Feng has already fully comprehended the five elements of metal, wood, water, fire, and earth, so he naturally no longer needs to hide his strength.

Once Ye Feng helps the Five Elements World resolve this disaster, he will leave the Five Elements World with Jiang Lingxuan and Sun Muqing and return to the real world!

Jiang Lingxuan and Sun Muqing were not idiots; they quickly grasped the hidden meaning in Ye Feng's words.

"You've already mastered the Earth Element True Qi? So fast?" Sun Muqing said in surprise.

“It was supposed to take much longer, but the Black Earth Sacred Mountain that Zhuoer took me to is truly a wonderful place. The earth elemental veins there have provided me with tremendous help. Even without the complete Imperial Earth Technique, I have already perfected my understanding of earth elemental true energy,” Ye Feng said with a smile.

"That's great! In that case, we don't need to hide our strength anymore. Even if we expose our identities, it's no big deal!" Jiang Lingxuan said with a smile.

"You must be careful. We are only helping the Five Elements World; we cannot risk our lives," Night Wind warned.

“Of course we understand,” Sun Muqing said with a smile.

Therefore, Jiang Lingxuan and Sun Muqing no longer concealed their strength and immediately unleashed their full power to kill one demon after another.

Seeing that Jiang Lingxuan and Sun Muqing's strength had greatly increased, Zhuo Dun, who was in the distance, was immediately startled.

"Night Wind, you've come out of the Holy Mountain? Strange, how come your two beloved wives have suddenly become so powerful? Late stage of True Essence Realm? Is this for real or not?" Zhuo Er said in surprise.

Zhuo Er wasn't the only one who was surprised.

In the past few days, Jiang Lingxuan and Sun Muqing have been helping the Underworld Sect resist the attacks of the demon race. The two of them have only shown the combat power of the peak of the Separation and Union Realm.

But now, the two of them have revealed the strength of the ninth level of the True Essence Realm, which is bound to shock those who know them!

"Don't ask so many questions, this isn't the time for idle chatter," Ye Feng said.

Then Ye Feng suddenly took flight and soared into the sky.

At the same time, Ye Feng released a vast aura, and a powerful pressure swept over the ground, shocking the demons and warriors of the Netherworld Sect.

"Entering the Saint Realm... This is the aura of someone who has entered the Saint Realm! Mr. Feng is actually a living Saint?"

"Is this real? Is it just my imagination or..."

Zhuo Er stared in shock at the night wind soaring into the sky, finding it hard to accept the fact for a moment!

A thousand feet in the sky.

Six figures were locked in a fierce battle.

The Netherworld Sect Master Shi Ji is fighting against the Heavenly Mountain Great Sage, while Xia Lie is fighting against the Crimson Flame Great Sage, and the Spirit Water Sect Master Nan Lingrong is naturally fighting against the Profound Ice Great Sage.

The Great Sage of Tianshan is the largest, like a small mountain, and thick arms grow all over the mountain.

The Crimson Flame Great Sage looks like a giant ape engulfed in raging flames, and in his hand he holds a thick, long club that is also burning with flames!

Xuanbing Great Sage was completely different from the two demon race Great Sages. She looked like a human woman, only a size larger.

She had a beautiful face, a head full of snow-white silver hair, and was always surrounded by a storm of snowflakes!

At this moment, the six Saint Realm experts were locked in fierce combat, their battle evenly matched.

The intense fluctuations of true energy created a chaotic energy field in the air, making it impossible for martial artists and demons below the Saint Realm to get close. If they were caught in it, they would probably be torn to shreds immediately!

"Sect Master of the Underworld Sect, stop resisting! Do you think our Heavenly Demon World only has this much fighting power? Let me tell you the truth, our Heavenly Demon World still has three Great Saints who haven't come yet, otherwise your Five Elements World would have been flattened by our demon race long ago!" The Great Saint of Tianshan said with a wild laugh, his extremely ugly face revealing an arrogant and smug expression.
