"Afu, bring the treasure box over here," Zhang Bairen commanded.

"Yes, Master!" Afu, whose body was inscribed with magical runes, walked up to Zhang Bairen.

As Zhang Bairen took the Panku Treasure Box, this unassuming magical artifact underwent a miraculous transformation. The entire box was first enveloped in a ghastly green light, and then suddenly released a beam of the same green light, which struck the stone lock on the temple gate.

Bathed in green light, the keyhole, originally shaped like a key, changed, gradually revealing a three-dimensional engraved keyhole with a nine-palace eight-trigram pattern underneath, which corresponded exactly to the pattern on the Panku Treasure Box.

"The gates of hell are about to open! Ah Fu, Valon, Dao Long, all of you step back!" Zhang Bairen warned.

Just as the sound faded, the Panku Box, enveloped in green light, suddenly floated up and flew swiftly towards the keyhole, fitting perfectly inside.

The next moment, the Panku Box shot out a ghastly green beam of light, which landed on the ground.

The beam of light landed, then spread out horizontally, and before Zhang Bairen's eyes, a huge door frame, hundreds of meters high, suddenly rose from the beam of light!

The ghastly green door frame exuded despair and eeriness, while inside the door was a massive vortex of blood red and earthy yellow, like a deep black hole.

Afu's sixth sense gave him a very dangerous warning. Immediately afterwards, a cruel and violent aura swept across the world. A huge claw, several meters long and covered with dark green skin, slowly emerged from the Gates of Hell and reached out to grab Afu and the others.

It turned out that Bo Gang sensed that Afu and the others were standing together and not holding the treasure box, so he chose to launch an attack.

"Insolence!" Zhang Bairen roared, and a dazzling sword mountain rose from the ground, instantly severing Bo Gang's disgusting arm.

Ugh!

Ouch!

"Bo Gang's screams and roars spread out in the form of sound waves."

"Bo Gang! I released you not so you could fight my people!" Zhang Bairen's voice neutralized the demonic sonic wave and even caused Bo Gang to almost stumble backward.

A moment later, a huge, dark green head emerged from the gates of hell, but its face was contorted with a look of agonizing pain.

After Bogang's enormous and obese body squeezed out of the Gates of Hell, Afu realized that the huge hand reaching for him was pitifully small compared to the demon's size.

It has a fat and bloated body, dark green demonic skin, and yellow protrusions representing rocks and clods of earth. Its short, thick arms and legs look disproportionate. Inside its hideous, blood-red mouth are densely packed, interlocking, terrifying teeth. On its ugly head is a Japanese-style topknot.

At this moment, the mountain demon, Bogang, officially left hell and descended upon the human world once more!

The green light suddenly disappeared, the Gates of Hell vanished, and the Panku Box returned to its original shape, but the enormous Pogan remained in this world.

Having already suffered a loss, Bo Gang did not attack again. Instead, he picked up his severed arm and placed it on his wound.

As the green light flashed, Bo Gang's injuries were instantly healed.

"Human, do you have a request for me after you released me?" Bogang asked politely, suppressing his hunger.

"I have no requests, I just want to release you." After saying this, Zhang Bairen led Daolong and the others away.

Bo Gang was stunned for a moment, then, drooling, he stuck out his freely elongated tongue and swallowed the surrounding land and trees into his gaping maw.

A moment later, Bo Gang arrived at the river mouth, lay down, and began to drink water in large gulps.

As Bo Gang inhaled sharply, it was as if an abyss had appeared, and endless seawater surged into his body.

Glug, glug, glug...

After drinking about 30% of their fill, the nearby riverbed had completely dried up.

Bo Gang's body has also become even more obese and enormous.

Stimulated by the seawater and feeling slightly full, Bo Gang, whose mind was temporarily clear, felt the influence and blessing of the black energy.

"Something's not right. The swirling black aura is a bit too outrageous."

"Could it be because there are too few demons?" Bo Gang wondered to himself.

But the next moment, she thought of the Holy Lord.

"No! Absolutely not!"

"Where is the Holy Lord? Where is the Holy Lord's aura? Where is the Holy Lord's fiery magic?!" Bo Gang's heart instantly panicked.

In the sky, Zhang Bairen led the group to observe Bo Gang below.

"Master, this demon seems to have discovered something," Daolong said.

"Yes, that's true."

It was a brainless thing that suddenly gained a little brainpower.

It's probably because the Holy Lord died that the Black Qi panicked, which is why it increased Bo Gang's brain capacity.

But so what!?

Whether or not Bo Gang becomes smarter, she now only has two paths to take.

They can either give up the struggle and choose to wait for death on the spot.

"Either you restore your strength as much as possible, devour everything, and rely on the amplification of the black energy to fight me!" Zhang Bairen replied.

"Master, should we deal with the black energy?" Daolong asked again.

"No rush, take your time."

First devour the demon, then devour the black mist.

This world doesn't need messy rules.

"Only I am the sole will!" Zhang Bairen replied casually.

Bo Gang, who had already guessed the general situation, froze on the spot.

It wasn't until the dark energy surged that the mountain demon regained some confidence in turning the tide.

Looking at the bustling city not far away, Bo Gang's eyes gradually turned bloodshot and terrifying.

"Damn humans! Once I've filled my stomach and regained all my power, this world will be mine again!"

"And you, too, will be swallowed by me and digested into dust!" Bo Gang, whose confidence had been amplified by the black energy, muttered to himself.

Having already set its sights on Mount Fuji, the mountain demon charged headlong towards it.

Along its journey, Bo Gang devoured and destroyed everything in its path, leaving behind only ruins and the extinction of all living beings.

Soon, this mountain demon was subjected to a barrage of fire from humans.

The descendants of the Onmyoji who had dealt with the Shadow Legion in the past, as well as the royal high priests, quickly contacted the Japanese government and requested immediate intervention.

Thanks to the convenience of technology, intelligence agencies from various countries have also become aware of Japan's crisis and situation.

Leaders from around the world are closely watching Japan's response and its outcome.

At this moment, the battle between humans and demons has begun. Faced with the weak human army, Bogang, the demon of the mountains, finally showed a little bit of what a demon should look like.

Bogang's skin is indestructible; even powerful missiles and armor-piercing rounds cannot penetrate his physical defenses.

Despite the endless barrage of bullets and missile bombardments, Bo Gang was not harmed in the slightest. Instead, all the self-defense forces that launched the attack became his meal.

"Food! I want more food!"

"Bogang's tongue danced in the air, constantly swirling in various foods, while his short legs kept moving as he ran towards Tokyo, the most populous city."

Its two short, powerful arms would grab trees and buildings from time to time and stuff them into its mouth without hesitation. Its infinitely long tongue, like a python, would coil around Self-Defense Force members and fleeing Japanese citizens.

Faced with the overwhelming ferocity of the Demon Lord, humanity was utterly powerless to resist!
