This is the largest upheaval that has occurred within the ten great clans of the Demon Beast Dynasty on the Haotian Continent for thousands of years. Aside from the Split-Sky Blue Sky Beast Clan, the other nine clan leaders have either been defeated or directly killed, and scenes of old kings falling and new ones ascending played out one after another.

Those who replaced the original clan leaders were all the Demon Saints of each clan who were sent to guard the Divine Tree in the Divine Tree Domain due to some mistakes or conflicts.

Their power advanced rapidly in just a few hundred years, far surpassing their former clan leaders, and it is rare to find any in the history of the great clans who can compare with them.

As for what exactly happened during this period, no one knows.

However, under the protection of the nine Demon Saints, no one had the courage or ability to intrude into Zhang Menglong's breakthrough area. As the thunderclouds dissipated and the World Force faded, it was announced that Zhang Menglong had successfully broken through to the Heaven-breaking Realm!

"Menglong succeeded!"

"Good lad, truly a freak. This aura, his Mystic Qi cultivation is almost at the human Mystic-Breaking Realm, right?"

"You guys stay here and guard, do not let anyone in or allow anyone to intrude!"

The nine Demon Saints who had already seized the clan leader positions in their respective clans immediately had their elders guard the surroundings, while they themselves rushed to Zhang Menglong's side.

Zhang Menglong emanated a divine radiance, absorbing the power of these thunders. Having cultivated several Body Refining Techniques and martial arts to the extreme, he achieved Physical Sanctification, able to unleash Demon Saint-level attacks with ease.

His Mystic Qi cultivation instantly elevated from the True Martial Realm to the peak of the Heaven-breaking Realm!

At that moment, the Earth-based Universe Seven underwent a tremendous transformation.

Zhang Menglong possessed a powerful contract with the world's origin, and with his upgrade to the Heaven-breaking Realm, Universe Seven began its transition from a low-level world to a mid-level world!

The first step was the strengthening of the Laws, the enhancement of Energy, and the fundamental enhancement of all life forms.

Life on Earth, originally at the most elementary level, now started from the Universe Seven's promotion. Even a newborn on Earth now possessed a life level of Elementary Level Two strength.

Within a massive bubble of countless mid-level worlds, a small bubble of Universe Seven appeared.

Of course, though Universe Seven was now promoted to a mid-level world, it remained the weakest, requiring Zhang Menglong to frantically plunder resources and energy to help raise its level.

"Menglong, congratulations, your power has taken yet another step forward!" the nine Demon Saints exclaimed in congratulations.

"Hahaha, there's nothing worth congratulating compared to you brothers and sisters," Zhang Menglong remarked. Though he had been dealing with the Tribulation Thunder earlier, he hardly paid much attention to it and was instead rather intrigued watching the nine Demon Saints ascended to power, "Congratulations to you brothers and sisters for becoming the trusted Clan Leaders for your respective races."

"This is all due to your contributions, Menglong!"

"Indeed, we've thought it over. Previously, our ten great clans were constantly warring among ourselves. Now that we are sworn brothers, we've decided to unite into a real Demon Beast Empire, consolidating all our strength."

"Yes, that's right. Our ten great clans will be the core of this Empire, so humans will no longer dare to invade us on a whim."

"Wait, so who should be our leader now?" Liman suddenly suggested, "Our ten great clans originally maintained this old situation due to refusal to submit to each other, and we can't solve this problem now."

"Right, who will make decisions if conflicts arise?"

"Is that even a question?" Sen Wanxiang's gaze fell on Zhang Menglong, "Of course, we'll support Menglong as our king."

"Indeed, although Menglong is a human, we all acknowledge him. There's no one else fit to be the Demon King!"

"Huh?" Zhang Menglong hadn't anticipated they'd suddenly propose this, reminding him of Xu Que from the Blast Sky Gang and his infamous deeds. Was he to become a troll king himself?

"Um, actually, I'm not quite suitable for this," Zhang Menglong said, "A human being the Demon King sounds quite far-fetched. Plus, I like to show off and wander everywhere, and you wouldn't be able to find me. I suggest you races take turns governing, ten years for each race, with the other nine supervising, which should solve your issues."

"Yes, that's also a way."

"Menglong sure has lots of ideas."

"Alright, brothers and sisters, I've completed my breakthrough. I need to help my friend find his father, let's gather again when we return from the forbidden area!"

"Be careful in everything!"

...

"Brother, Menglong is heading to the forbidden area. Are we really not going to stop him?" Liman was still somewhat worried.

"Do we still need to worry about Menglong?" Sen Wanxiang laughed, "I think it might be more reliable for us to worry about those beings in the forbidden area instead."

"Hahaha, indeed. Whatever others can do, Menglong can do, and whatever others can't do, he can likely do as well. Let's stop worrying unnecessarily."

"Everyone should return. We each need to clean up our own clans!"

"Yes, that old rat's followers are many and can't be left as future troubles."

...

"Brother Zhang, you finally returned!" Zhang Menglong had been away for several days this time, and Kong Lan was worried sick, "Did everything go smoothly?"

"Yes, it went quite smoothly," Zhang Menglong said, "I even adopted nine brothers and sisters from the other nine great clans. They are all the clan leaders of their respective races now."

"What?" Kong Zhi by the side twitched his lips. Weren't the members of those nine great clans just some high-level Demon Saints? There was an insurmountable gap between their strength and that of their former clan leaders. How could the clan leaders of the nine great clans change? What's going on?

At this moment, a member responsible for gathering intelligence from various races for the Blue Sky Beast returned.

"Clan Leader, something major happened. All former clan leaders of the nine great clans were killed, and new clan leaders have ascended. It's confirmed these new leaders were the ones guarding the Divine Tree, but what exactly happened is still unclear. Reliable intelligence suggests those old clan leaders were almost all killed with a single strike!"

"Hiss!" Kong Zhi gasped.

When he took Zhang Menglong to the Divine Tree Domain, those nine Demon Saints were very wary of him. His strength was about on par with those clan leaders, perhaps just slightly stronger, but definitely not enough to kill them with a single strike!

If they had such power back then, they wouldn't need to be wary of him.

This means, their strength must have surged after he left, and this is undoubtedly connected to Zhang Menglong!

He single-handedly changed the situation for the nine great clans of the Demon Beast Dynasty!

Thinking of this, he suddenly breathed a sigh of relief. If it weren't for his elder's and his family's old friendships, he himself would probably have been replaced by a Demon Saint guarding the Divine Tree Domain by now!

Thinking about it like this, he actually felt somewhat lucky!

His gaze toward Zhang Menglong became increasingly reverent.

"This man... is invincible!"
