Chapter 2496: God-Killing Sword

"Master, I have the urge to advance."

The weapon spirit of the Demon-Slaying Knife appeared, with a very painful expression on its face: "But the strength is quite lacking, so I can't have both!"

"Want to advance but don't have enough strength?"

Cheng Feng thought thoughtfully: "Could it be that the demonic energy you absorbed before allowed you to meet the standards for promotion?"

"But you don't have enough weapon essence to absorb, so you can't advance."

"Yeah, almost."

The weapon spirit of the Demon-Slaying Knife nodded, the look of pain on his face getting darker.

"This is easy to handle."

Cheng Feng nodded, took out all the weapons in his soul ring, and threw them all to the demon-slaying knife for it to swallow.

But not enough!

Far from enough!

So Cheng Feng took out a sword, a Buddhist weapon at the level of a top holy weapon.

When Buddhist monks saw this weapon, they all went crazy for it. It was priceless.

But Cheng Feng didn't even look at it and threw it directly to the demon-slaying knife.

Wow~~~

The demon-slaying sword melted completely and wrapped the sword.

In the blink of an eye, the essence of the sword was absorbed by the demon-slaying sword.

However, it is still not enough for the Demon-Slaying Sword to enter the top holy weapon level!

After thinking about it, Cheng Feng smacked his eyebrows.

A black knife appeared, which was the treasure that Cheng Feng had blackmailed from King Gu Yao.

It is rumored that this object was polished from the fragments of a supreme holy weapon.

This object can carry the will of the supreme sword and is Cheng Feng's trump card for killing enemies.

But this time, in order to let the Demon-Slaying Sword advance, he gritted his teeth and threw it to the Demon-Slaying Sword.

The black knife is indeed a fragment of the supreme holy weapon.

After being wrapped by the demon-slaying knife, the blade exuded a thick black aura.

The entire Blood Flame Mountain was plunged into thick darkness.

The sword demon was recovering from his injuries when he was suddenly awakened.

Seeing the horrifying scene in front of me, I thought that the coffin of gods and demons had escaped from the trap, and the sword intent was rolling all over my body, piercing the sky of the secret realm of Blood Hell!

"Sword Demon, don't get excited!"

Cheng Feng hurriedly reassured: "My weapons are being upgraded, don't worry!"

The explosion of the sword demon allowed Cheng Feng to see how powerful the sword demon was.

Eighty percent of the supreme sword willpower is enough to instantly kill a true saint with thirty lines!

Even against a perfection-level half-saint, he can still compete for supremacy.

"Is your weapon being upgraded?"

Hearing this, the sword demon took a long breath: "I was shocked just now. I thought the gods and demons had escaped from the coffin!"

At this time, not only the sword demon was frightened.

The existence in the coffin of the gods and demons was also shocked.

After stopping the collision with the Demon Subduing Formation, a surprised voice came from the coffin.

"A fourth-level magic weapon is advancing to the fifth level?"

"It's really interesting to see the birth of a fifth-level magic weapon in a place like this!"

After the words fell, buzz~~~

The demon-slaying knife wrapped in a black knife suddenly surged in demonic energy.

It was like a black mushroom cloud rising on the Blood Flame Mountain.

A large amount of weapon essence exploded as the demonic energy surged.

Wow~~~

The Demon-Slaying Knife absorbs it crazily.

The surrounding demonic energy surged as if being torn apart by a tornado.

While breathing, he retracted his demon-slaying knife again.

Not only that, the suction force also penetrated the demon-subduing array and took away most of the black energy emitted by the coffins of gods and demons.

The demon-slaying sword that was constantly transforming finally stabilized its form.

It turned into a ferocious dragon-shaped black knife.

The handle of the knife is the mouth of the black dragon, the blade is the torso of the black dragon, and the tip is the tail of the black dragon.

When the black knife was flying, it was like a demon dragon dancing.

It was so fierce and powerful that it was so overwhelming that it was difficult to breathe!

"Hoo~~~"

Seeing this scene, Cheng Feng's eyes widened: "Demon Slayer, have you finally advanced?"

"Huh? It seems it's not complete yet..."

Cheng Feng originally thought that the Demon-Slaying Sword had completed its promotion.

Just as he was about to pick it up, he suddenly felt that the Demon-Slaying Sword was still a little incomplete.

There seems to be something that has not grown on the blade covered with dense black scales.

However, Cheng Feng no longer had any weapons on his body for the Demon-Slaying Sword to devour.

Unless the Thousand Machine Tower, God of War Armor, Sky Burial Flag... these commemorative things are thrown to the Demon-Slaying Sword to swallow them up.

"Cheng Feng, let me help you."

At this moment, the sword demon suddenly shouted.

The next moment, phew~~~

The sword in his hand was actually thrown at the Demon-Slaying Sword.

Not only that, the sword demon also put the middle finger and index finger of both hands together and stabbed the demon-slaying knife.

Whoosh! Whoosh! Whoosh!

Swords flew out of the sword demon's body one after another.

Like a shock of sword rain, it flew towards the Demon-Slaying Sword!

The quantity is huge, tens of thousands of pieces!

"So many swords?"

Seeing this scene, Cheng Feng was shocked: "These swords must have been collected by the sword demon over the years, right?"

"Each one is a fine product, and some of them are swords that are comparable to the top holy weapons!"

"Absorbing the essence of these swords, slaying demons is enough to reach the top holy weapon level, right?"

Wow~~~

Cheng Feng just finished speaking.

In the sky, the handle of the demon-slaying knife suddenly opened and turned into a ferocious dragon's mouth.

He swallowed all the tens of thousands of swords thrown by the sword demon into his mouth.

The next moment, the blade of the demon-slaying knife became deeper and heavier.

The pieces of black dragon scales are like steel poured into iron, giving people an indestructible feeling.

The blade is even more impressive, incredibly sharp.

Especially near the handle of the demon-slaying knife, there was a writing like an iron hook and a silver stroke.

The words were not human words, but Cheng Feng could understand them.

It only took one glance to tell that it was the word "kill"!

"kill?"

Cheng Feng raised his eyebrows: "Is this word the real name of Demon Slayer?"

When Cheng Feng got the Demon-Slaying Sword, the word "Demon-Slaying" was engraved on the blade.

Cheng Feng thought that Demon Slayer was the name of the Demon Slayer Sword.

Now the Demon-Slaying Sword has changed, and a new character has appeared. Perhaps this character is the real name of the Demon-Slaying Sword!

"Kill? Could it be that this sword is actually the God-killing sword?"

Just as Cheng Feng was thinking to himself, a suspicious voice came from the coffin of gods and demons.

He seemed to have seen something incredible, which surprised him!

"God-killing sword?"

After hearing this, Cheng Feng hurriedly asked: "Do you know the origin of Demon Slaying? Is its real name the God-killing Sword?"

"Impossible. The God-killing Sword is a weapon of the Bing Demon Clan. It has always been controlled by the Clan Saint of the Bing Demon Clan. It is impossible for it to appear here."

The being in the coffin of gods and demons did not answer, but said to himself: "This knife should be a counterfeit, with some charm of the God-killing Knife. Even I was almost deceived!"

The existence in the coffin of gods and demons seems to know the demon-slaying knife.

At this moment, he decided that the Demon-Slaying Sword was a counterfeit, and his excitement gradually calmed down.

But Cheng Feng's thoughts were swirling in his heart, and he shouted: "Hey, what's going on with the God-killing Sword?"

"The God-killing Sword is a ninth-grade magic weapon!"

Cheng Feng originally did not expect an answer from the being in the coffin of gods and demons. Unexpectedly, the other party actually answered: "In the entire demon world, there are only a dozen or so!"
