High-level martial arts: Contract cashback, invincible starting from the Zerg.

After the Black Rose incident, Chen Feng suddenly realized that the Starry Sky Heroic Souls, besides being useful to Demon Slayers, might also be quite attractive to powerful beings from other planes.

Chen Feng had carefully read the Demon Slayer Handbook when he was at the Combat Academy.

As clearly stated above, each Exorcist's Vajra Core may contain powerful heroic spirits from other dimensions, and whether or not they can awaken and use the power of these heroic spirits depends entirely on the Exorcist's awareness.

This is why Chen Feng's next rank will be Starry Sky Demon Slayer, not Platinum Demon Slayer...

"Kid, you actually dare to challenge the people of Dark City, you've got guts!" Starry Sky Heroic Spirit said in Chen Feng's sea of ​​consciousness.

"Is Dark City a prime material world, senior?" Chen Feng replied.

Starry Sky Heroes smiled.

The voice, which had originally carried a hint of arrogance and playfulness, suddenly deepened, as if carrying the chill and vicissitudes of billions of years of starry sky, slowly spreading in Chen Feng's sea of ​​consciousness.

Even the surging spiritual energy in Chen Feng's sea of ​​consciousness stagnated somewhat.

"Then let me tell you my story."

In a realm called the Dome Universe, there are hundreds and thousands of prime planes, and the Dome Divine Realm is not only the origin of those thousands of planes, but also the end of all cultivation paths in this universe.

Within the Dome of Gods, powerful individuals abound. Even in a super-large prime plane, those who can achieve the Universe level are extremely rare. However, within the Dome of Gods, dozens of Universe-level powerhouses from various planes have gathered.

"Back then, I was one of them. With a single thought, I could move galaxies; with a single force, I could suppress the boundary. Even the second-generation Demon Lord of the largest Dark City plane had half of his demonic body shattered by my sword, causing their development to be delayed by more than a hundred years... However, even as a god, I still couldn't defend against the knife coming from behind."

Hearing this, Chen Feng was deeply shocked.

The strongest individuals recorded in the Demon Slayer's Handbook that Chen Feng saw did indeed include several Universe-level powerhouses.

What Chen Feng never expected was that the legendary being slumbering within the Vajra Core that had given him such power!

A chilling aura suddenly emanated from the voice of the Starry Sky Heroes.

It was as if, at this very moment, he was recalling the indelible betrayal of the past.

Meanwhile, within Chen Feng's sea of ​​consciousness, a tragic illusion of shattered galaxies and blood-stained divine realms faintly appeared.

"The one who betrayed me was Ling Ye, a powerful expert at the Universe level whom I regarded as my own brother and whom I personally selected as the successor to the divine title."

"After his clan was defeated, I took him back to the temple. I bestowed upon him all the secret techniques of the starry sky, and even gave him resources and authority that others could only dream of, in an attempt to make up for the bitterness he felt in his heart. But what I did not expect was that what he had always wanted was my universe-level origin."

"Ever since that great war of the gods that swept across the galaxy 120,000 years ago, he has been plotting how to kill me."

The voice of the Starry Sky Heroes weakened, carrying the weariness of a remnant soul wandering for endless years.

"After my fall, my remnant soul was constantly hunted down by Ling Ye's subordinates, and fewer and fewer of my clones managed to escape."

"By sheer chance, I discovered that the most powerful demon slayer in the Great Xia plane was about to appear, so I directly fell into your Vajra Core and fell into a deep sleep, only fully awakening when you touched the threshold of the Heavenly Rank..."

Chen Feng suddenly realized the truth.

No wonder Black Rose wanted the Starry Sky Heroes' Souls so much...

The Dark City behind her has never forgotten the humiliation of having its half-demon body shattered, nor has it given up its covetousness for the ultimate power of the Divine Realm above the plane.

The remnant soul of each of the Starry Sky Heroes is the key to their resurgence and revenge.

As Chen Feng reviewed the memories of the Starry Sky Heroes, his body grew increasingly cold, and his mental energy surged violently within his sea of ​​consciousness.

The memories of those galaxies shattering and the divine realm stained with blood are so shocking.

Even Chen Feng couldn't believe that a full-force attack from a legendary Yu-level expert could directly destroy a hunting plane.

"Senior, if you were betrayed by your own people, wouldn't there be no one to help you return to the Starry Sky God Realm?" Chen Feng asked.

The voice of the Starry Sky Heroes remained silent for a moment.

However, he soon said to Chen Feng, "After my fall, Ling Ye took away most of my Universe-level power and inherited my authority in the Starry Sky Temple, becoming the new Lord of the God Realm. Of course, no one will offend him for my sake."

Hearing this, Chen Feng finally understood.

That mad, celestial spirit shared a strikingly similar experience to his own.

They were all betrayed by their trusted confidants and lost all their cultivation, ending up in an extremely pitiful state.

Recalling the contemptuous looks Su Yao and Zhao Wuji gave him at the end, a surge of anger quietly rose in Chen Feng's heart.

Chen Feng clenched his fist, and the Vajra Core within his body seemed to begin to heat up slightly.

"Senior, I will break through to the Starry Sky Demon Slayer level as soon as possible. If I can control the power within your Starry Sky Heroic Soul, perhaps I can help you take revenge."

Within his sea of ​​consciousness, the laughter of the Starry Sky Heroes slowly resounded.

However, it was no longer the arrogant and playful tone of before, but rather tinged with a sense of relief and anticipation.

Like a galaxy that had been silent for 120,000 years, finally welcoming a glimmer of light.

"Boy, the power of this remnant soul of mine is only 10% of that of my original body. Even if I were to bestow all my power upon you now, I'm afraid you still wouldn't be able to break through to the Cosmic Level. To become a Cosmic Level expert, you would need to kill at least one colossal beast and its army of giant beasts before you could fully advance."

"Starry Sky Heroes explained."

"Although you can't help me, I've decided to strengthen your Vajra Core in consideration of your past kindness to help you break through to the Heavenly Rank as soon as possible."

As soon as he finished speaking, Chen Feng felt a powerful yet gentle force surge into his sea of ​​consciousness. That force, following his spiritual power, slowly merged into the Vajra Core.

It was a slightly hot diamond core, which at this moment was like a star that had been ignited, emitting a dazzling silver-white starlight, and forming a faint starry sky barrier around him.

At this moment, Chen Feng seemed to be able to clearly feel that all his attributes were improving rapidly, and the impurities in his Vajra Core were being slowly purified by the power of the Starry Sky.

His strength, which was originally stuck at the peak of the Earth Rank, is now steadily increasing under the pull of the Starry Sky Power!

"Senior, I haven't asked your name yet."

"You can call me Chen Xing Liu."
