The center of the Origin Continent, the Forbidden Zone.
This place is also known as the Heart of Heaven.
This is the core of the Origin Continent, the forbidden land of the entire Upper Realm.
Legend has it that deep within the Heart of Heaven lies the Seed Source of the Origin Upper Realm.
All the rules of the Origin Upper Realm, as well as the powerful world force, are derived from that Seed Source.
This place is filled with powerful world force year-round, which will kill anyone who dares to step into the forbidden land.
Once, an ultimate expert with three Seed Sources coveted the Seed Source of the Origin Upper Realm and attempted to forcibly enter the forbidden zone.
And that ultimate expert was quite high-profile in his actions, publicizing his intention everywhere and setting a time for breaking into the Heart of Heaven.
It was precisely because of that ultimate expert's high-profile publicity that on the day he was about to force his way into the forbidden zone, large sects from the entire Origin Upper Realm, and countless ultimate experts, gathered at the periphery of the Heart of Heaven, wanting to witness that ultimate expert's attempt to break into the forbidden zone.
Even those ultimate experts who were conquering the Lower Origin Realm rushed back.
Although the essence of all Seed Sources is the same, the energy intensity they contain is ultimately different... The reason why the Origin Upper Realm is called the Upper Realm is because the energy of its Seed Source is the most powerful among all Seed Sources.
If they could obtain the Seed Source of the Origin Upper Realm, the ultimate experts could not even imagine how strong they would become!
If that ultimate expert successfully entered the forbidden zone, the ultimate experts watching would definitely not just stand by outside the Heart of Heaven; they would rush in to contend for the Seed Source.
Once that ultimate expert succeeded, the Origin Upper Realm would likely witness an unprecedented great battle, with countless ultimate experts in chaos, and perhaps the Origin Upper Realm itself would be destroyed!
At that time, all the ultimate experts knew what consequences would arise if the ultimate expert attempting to break into the Heart of Heaven succeeded.
However, to everyone's horror, even though that top ultimate expert used countless defensive treasures and made thorough preparations, he was instantly killed by the infinite world force the moment he stepped onto the edge of the forbidden zone.
That ultimate expert with three Seed Sources turned to dust in an instant!
It was precisely because that top ultimate expert was instantly killed that all the top ultimate experts in the Origin Upper Realm reached a consensus: they must absolutely not approach the Heart of Heaven!
Therefore, all the ultimate experts in the Origin Upper Realm, over a thousand in number, joined forces to construct an unprecedented ultimate barrier around the Heart of Heaven, precisely to prevent any more foolish people from approaching the Heart of Heaven and causing tragedy again.
But, no one expected...
At this moment, a fierce battle was taking place within the Heart of Heaven.
Tian Xing, carrying the World Extinguishing Spirit Fire, was fleeing in disarray within the outer perimeter of the Heart of Heaven, inside the barrier constructed by the ultimate experts.
Behind her, she was being pursued by lightning puppets condensed from world force.
"Damn it... these guys are truly persistent!" Tian Xing glanced back at the lightning puppets relentlessly chasing her, her expression extremely grim.
After she parted ways with Ye Ling, she had prepared to leave the Origin Upper Realm to find Xuan Yu and Bai.
But she never expected that Xiao Mao Mao, as a primal immortal beast, was always protected by the world force and could not leave the Origin Upper Realm at all!
The moment Tian Xing, along with Xiao Mao Mao and the Myriad Poison Beast, attempted to leave the Origin Upper Realm, they were located by the world force.
Then, Tian Xing had a confrontation with the world force of the Origin Upper Realm within a spatial rift and was ultimately pulled into the Heart of Heaven by the world force.
Facing the massive world force of the Heart of Heaven, Tian Xing and the World Extinguishing Spirit Fire were initially unable to resist and would have been instantly killed. However, at a critical moment, Xiao Mao Mao stepped forward, using his own power to send Tian Xing and the World Extinguishing Spirit Fire out of the Heart of Heaven.
The price was that Xiao Mao Mao remained forever within the Heart of Heaven.
But... although Tian Xing and the World Extinguishing Spirit Fire were sent out of the Heart of Heaven by Xiao Mao Mao, they were completely unable to break through the ultimate barrier jointly constructed by a thousand ultimate experts.
Thus, Tian Xing and the World Extinguishing Spirit Fire were trapped between the Heart of Heaven and the ultimate barrier, constantly evading the pursuit of the world force.
The World Extinguishing Spirit Fire said anxiously, "Tian Xing, this cannot go on... We cannot replenish our strength here, and we will eventually exhaust our spiritual power and die here!"
Tian Xing quickly asked, "Do you have any ideas?"
The World Extinguishing Spirit Fire said, "I've observed the outer barrier and found a few slightly weaker spots. Head towards them, and I'll try to detonate my Seed Source to see if I can blow open a gap. You can escape then!"
Upon hearing the World Extinguishing Spirit Fire's words, Tian Xing refused without thinking, "No! Isn't this trading your life for mine?"
"If not, we'll both die!" the World Extinguishing Spirit Fire shouted, "And I'm just detonating the Seed Source, not self-destructing. You just need to seize the opportunity to take me out, and then we'll both have a chance to survive!"
Tian Xing said, "If that's the case, I can also detonate my Seed Source. You seize the opportunity to escape."
"Why don't you understand?" the World Extinguishing Spirit Fire said somewhat anxiously, "Ye Ling only left a mark on you, and you still have that half of the World Suppressing Bead. Only if you get out, you have a chance to find Xuan Yu and Ye Ling. If I get out... then we'll be completely separated!"
"World Extinguishing Spirit Fire..." Tian Xing's eyes were filled with hesitation upon hearing the World Extinguishing Spirit Fire's words.
"Don't hesitate! Those puppets are about to catch up again!"
The World Extinguishing Spirit Fire quickly shouted, then cut off a piece of his soul and handed it to Tian Xing, saying, "Just in case, I'll leave a backup with you. If you can't save me in time, use my residual soul to revive me!"
"Keep up!"
After speaking, the World Extinguishing Spirit Fire didn't wait for Tian Xing's reply, but flew directly out of Tian Xing's wrist and chased straight towards the weak point of the barrier he had marked!
"World Extinguishing Spirit Fire!"
Seeing the World Extinguishing Spirit Fire charge out directly, Tian Xing's expression changed drastically, and she quickly chased after him, trying to stop him.
However, the World Extinguishing Spirit Fire's speed was about the same as Tian Xing's, and with the World Extinguishing Spirit Fire already igniting his Seed Source, it was too late for Tian Xing to stop him.
"Tian Xing, seize the opportunity and prepare to escape!"
The World Extinguishing Spirit Fire shouted loudly, charging headfirst into the ultimate barrier outside the Heart of Heaven. Cracks appeared on the surface of his Seed Source, and infinite energy permeated from his body.
Brilliant light emanated from the World Extinguishing Spirit Fire, illuminating the surroundings.
"World Extinguishing Spirit Fire!!!" Tian Xing roared, her eyes about to split.
"World Extinguishing Spirit Fire, I didn't expect you to be so manly!"
At this moment, Ye Ling's voice echoed around them. Immediately, the space next to the World Extinguishing Spirit Fire cracked open, and Ye Ling walked out. He grabbed the World Extinguishing Spirit Fire, suppressed the cracks in his Seed Source with runes, and then used his creation power to repair the damaged parts of the Seed Source.
"Ye Ling?"
Both Tian Xing and the World Extinguishing Spirit Fire were stunned by Ye Ling's sudden appearance.
And at this moment, the lightning puppets condensed from world force rushed up from behind and attacked Tian Xing!
Seeing this, the World Extinguishing Spirit Fire's expression changed drastically, and he quickly warned Tian Xing, "Tian Xing, be careful!!!"
"Don't worry, I'm here!"
At this moment, Nuo Ying's voice sounded.
Immediately, Nuo Ying appeared behind Tian Xing and punched towards those puppets!
"Eat my punch!!!"
Nuo Ying roared, unleashing a punch, and a powerful gust of wind swept towards the lightning puppets...
Boom!!!
In an instant, all the lightning puppets condensed from world force turned to dust!
