A void gate formed nearby, and three people walked out of it.

"Han Feng, Hong Jun, Luo Hou!"

The ancient demon spirit hadn't left and immediately recognized the three of them.

With the three ancient clan ancestors by his side, he roared, "You have some nerve, actually trespassing into our ancestral star system! Are you looking for death?"

"Get out, this is not a place where you can talk."

"The Demon Ancestor Rahu said coldly."

"OK!"

The ancient demon spirit's eyes glazed over, and it obeyed the command of the Demon Ancestor Rahu.

"This is the Great Dao of the Heart Demon. It's more powerful than I imagined. I didn't expect you to dare to appear here. If you dare to appear here, your cultivation level must have broken through to the Dao Heaven Realm. Otherwise, coming here would be no different from courting death."

The Demon Heart Ancestor scrutinized the three of them.

"His cultivation level has broken through to the Dao Heaven Realm?"

The Divine Ancestor exclaimed in astonishment, "This vast starry sky and this world were clearly sealed by us, making it impossible to break through to the Dao Heaven Realm. How could the three of them possibly have broken through to the Dao Heaven Realm?"

"Seal? What seal?"

Dao Ancestor Hongjun asked.

"As expected, the limit of our vast starry sky cannot be the late stage of the Heaven-Treading Realm. As for why the highest realm of our vast starry sky is stuck at the late stage of the Heaven-Treading Realm, it has a lot to do with your three ancient clans."

Han Feng learned a lot of hidden information from the Eastern Emperor in the Dao Domain.

The three levels of interfaces devour each other; no interface is particularly powerful from the start.

The Six Paths Great World is more powerful than the Dao Domain because it has devoured many third-level realms.

The Dao Domain is stronger than the Taixu Divine Domain mainly because the strongest person in the Taixu Divine Domain lost the contest.

The three demons survived using a secret technique, and the Dao Domain drained the Taixu Divine Domain dry by absorbing the Great Dao of the Taixu Divine Domain.

This also shows that it is not so easy for three-level interfaces to devour each other; it is still a gradual process.

For example, the Six Paths Great World and the Dao Domain are already so close that it will be difficult to find a way to devour each other unless the barriers between them are broken.

Han Feng learned the key to the mutual devouring of the three worlds, and also learned about the initial abilities of the three worlds.

The vast starry sky is not much smaller than the Taixu Divine Realm, which has three beings at the Earth Heaven Realm.

He believed that no matter how weak the vast starry sky was, it was impossible for its highest realm to be the late stage of the Heavenly Stepping Realm.

It now appears that the three ancient races are hiding many secrets, including why the vast starry sky has become what it is today.

Han Feng had previously searched for the ancient Xuan Divine Soul, but found no key information.

Now, Han Feng learns from the ancestor before him that it's not that the three ancient clans didn't have anything to do with the vast starry sky, but rather that Gu Xuan's level was insufficient.

"How about this, I can tell you the secrets of the vast starry sky and why you can't improve your cultivation level."

A mocking smile appeared on the Demon Moon Ancestor's crimson lips: "In exchange, how about you tell us how to break through to the Dao Heaven Realm?"

"It's easy to find out the method, just kill me. Of course, it's also easy for you to know my secret, just kill me."

Han Feng said expressionlessly.

"You're really confident in your strength. You three don't think you can contend with us just because you've just broken through to a higher realm, do you?"

The progenitor of divine power said disdainfully.

"Enough with the nonsense, let's fight."

"The Demon Ancestor Rahu said impatiently."

"You call the Demon Ancestor to master the Great Dao of the Heart Demon, but I am the ancestor of the ancient demon race and can also be called the Demon Ancestor. Today, I will have a good competition with you, the Demon Ancestor, to see who is the true Demon Ancestor."

The Demon Moon Ancestor immediately set his sights on the Demon Ancestor Rahu.

"Can."

Demon Ancestor Rahu said fearlessly, "Today I will show you what a true demon is."

With a thought, the entire inner demon world unfolded, heading towards the Demon Moon Ancestor.

In an instant!

The Demon Moon Ancestor was taken into the Heart Demon World by the Demon Ancestor Rahu and disappeared from everyone's sight.

"Then I will choose you, Dao Ancestor Hongjun. I have heard that you have a nine-layered Great Dao World. I will see if I can shatter your nine-layered Great Dao World with my power."

The Divine Ancestor set his sights on the Dao Ancestor Hongjun.

"Can."

Dao Ancestor Hongjun also used the Nine-Layer Heavenly Dao World to cover the Divine Power Ancestor.

"It seems I have no choice but to fight you."

The Demon Heart Ancestor gave a wry smile.

Actually, he was a little hesitant, unsure whether he should choose Han Feng.

Of the three, the most renowned were Dao Ancestor Hongjun and Demon Ancestor Luohou, due to their immense strength and profound understanding of the Dao.

Even the three ancient clan ancestors in the Dao Domain had heard of the two's reputation.

It's obvious that choosing Han Feng is much safer than choosing either of these two.

At the same time, he didn't want to choose Han Feng because Han Feng had killed a late-stage Sky-Stepping Realm expert, while the other two had not.

With that moment of hesitation from the Demon Heart Ancestor, Han Feng was left as his only opponent.

"It doesn't matter who my opponent is, they're all going to die anyway."

Han Feng said coldly.

"You're young, but you've got quite the nerve. Let's see just how strong you really are."

The Demon Heart Ancestor's body began to grow rapidly, soon surpassing the size of a planet.

"Are you not planning to use the Great Dao World and instead want to fight me with your physical body?"

He had received information from Han Feng that he had killed Gu Xuan with his own body.

At this moment, Han Feng was not using the Great Dao World; it was clear he intended to fight with his bare hands.

"You guessed right."

Han Feng took out his own Life Dao Tree and merged it into himself.

His body began to swell, and his size reached that of the Demon Heart Ancestor.

"It's one thing to compare physical strength with our ancient clan when you're in the late stage of the Heavenly Ascent Realm, but to compare physical strength with our ancient clan when you're in the Dao Heaven Realm is practically suicide."

Feeling scorned, the Demon Heart Ancestor angrily lunged at Han Feng.

He threw a powerful punch at Han Feng, intending to defeat him on the spot.

Han Feng was equally unafraid and threw a punch as well.

Their fists collided, producing a loud bang.

In this contest, Han Feng staggered back several steps, crashing into a nearby planet and making a cracking sound as his hand bones broke.

Most of the ancient races in the progenitor galaxy realized something was wrong and chose to evacuate.

However, many ancient clans failed to evacuate in time and were all killed when they were hit by Han Feng's physical body.

An ancient clan expert at the Heavenly Realm failed to evacuate in time and died from Han Feng's collision.

The battle between two Dao Heaven Realm experts was terrifying; experts below the Dao Heaven Realm simply couldn't intervene.

"Do you, a mere human, even deserve to compete with me in physical strength?"

The Demon Heart Ancestor laughed heartily.

Although he didn't defeat Han Feng in one fell swoop, injuring Han Feng was enough.

All that's left is to wait out; he's confident he can kill Han Feng.

"You don't think such a small injury can kill me, do you? Am I that fragile in your eyes?"

Han Feng's hand bones made a cracking sound as they gradually returned to their original state.
