It was just as Yang Dingtian had imagined.
There was no limit to how much Dark Mystic Flame could devour.
It was like a bottomless pit, continuously devouring, devouring, and devouring!
Did the Dark Mystic Flame have a huge breakthrough after devouring Mystic Qi?
Of course, the negative energy of the Dark Mystic Flame was getting stronger and stronger.
However, how big was it exactly?
Yang Dingtian did not know.
In short, as the Dark Mystic Flame devoured more energy, it did not become bigger, but smaller and thinner.
At first, the Dark Mystic Flame was the size of a fist, but as it devoured Mystic Qi, it became the size of a normal candle flame.
Later on, it became the size of a grain of rice.
Moreover, the smaller it got, the more energy it devoured.
It was so much that it started to affect Naga Shuang's share of energy devouring.
In the end, Yang Dingtian's Dark Mystic Flame was like a sharp black thread.
When Yang Dingtian released it, it felt like it could cut through everything.
Then, one day, Yang Dingtian could not help but try it. He released the Dark Mystic Flame that was as sharp as a thread and slashed it across.
As a result, the thick energy crystals were cut open alive.
The energy crystals that Yang Dingtian had a hard time digging with his soul sword that was close to the Emperor-grade were easily cut open by the Dark Mystic Flame like tofu.
Yang Dingtian was stunned.
He wondered if this Dark Mystic Flame could cut open the Chaos Emperor Armor and the Demon King's Sea of Vital Energy.
…
Finally, eighty days had passed since he had entered different energy crypts.
Yang Dingtian had broken through to the 24th level, and his Dark Mystic Flame had completely turned into a terrifying energy thread.
Along the way, Queen Poissa and Vulture also changed pyramids.
Finally, it was time to leave.
Yang Dingtian said to Naga Shuang, "It's time, we should go back."
Naga Shuang turned around and looked at the Old Naga Empire ruins that had shrunk a lot. Her beautiful eyes were filled with reluctance.
Then, she asked Yang Dingtian, "Husband, do we have to go back?"
"Of course," Yang Dingtian said.
Naga Shuang continued, "Then, are we still coming back?"
Yang Dingtian said, "Once we eliminate the Demon King, Xu Yantian, I will send you back."
Naga Shuang said, "Unfortunately, by that time, who knows how much of the energy in the ruins will have dissipated."
Yang Dingtian could clearly feel that she was reluctant to part with him from the depths of her heart.
Energy was the lifeblood of Naga.
Getting a Naga that was constantly devouring energy to leave its powerful body was probably the most difficult thing to do.
Naga Shuang kept gasping for breath. Then, she nodded and said, "Alright then, let's go and come back as soon as possible. We will try to come back within a month."
Then, Naga Shuang held Yang Dingtian's hand and flew away from the ruins of the Old Naga Empire without looking back.
Because she was worried that if she looked back, she would never be able to leave again.
…
Because of Naga Shuang, the speed of the four of them returning was indeed much faster.
In less time than before, they had already flown through the seemingly boundless Dark Void.
This shadow void was still deathly silent, and there were still distorted lights and shadows. There was still no sign of life.
At the end of the shadow void, there should have been an energy barrier. Medusa's trap enchantment.
However, the energy source of this Medusa's trap had been taken away by Yang Dingtian.
Therefore, this trap space was very abandoned and turned into an endless space of dead silence.
Yang Dingtian and the other three kept flying and flying.
Finally, they saw the incomparably huge statue of Medusa, which was tens of thousands of meters tall.
However, the statue of Medusa, which had lost two eyes, was now broken into several levels. It had become a huge ruin, floating in the silent void.
It looked especially lonely.
After flying for tens of thousands of miles in the abandoned trap space, the four of them hit the energy barrier.
Naga Shuang said, "At that time, I wanted to return to the human countries, but I was stopped here."
Yang Dingtian asked, "Did you encounter any accidents or dangers when you passed through Medusa's trap?"
Naga Shuang said, "Not at all."
Yang Dingtian thought about it and found it reasonable. This Medusa's trap space was to prevent other creatures from entering the Naga Empire. It would certainly not stop the Naga.
After flying through Medusa's trap space.
It was a boundless void of darkness.
After the countless dark matter swallowed to the extreme, it began to decompose. Pieces of dark matter condensed to the extreme, and after swallowing countless amounts of energy, it began to expand and expand.
When it expanded to the extreme, it became an incomparably huge dark void space.
There was nothing inside, only an infinitely large space, which had already surpassed the scope of the Chaotic World.
"Shuang 'er, your cultivation is too much higher than mine, so you may have to enter the space ring and jump through the space door," Yang Dingtian said.
Naga Shuang was a little unhappy, but she turned into a stream of light and flew directly into Yang Dingtian's space ring.
Then, Yang Dingtian opened the space door.
Poissa, Vulture, and Yang Dingtian jumped into the dark void space hand in hand.
With the lesson from last time, Yang Dingtian immediately summoned his near-Emperor-grade soul sword.
Then, the three of them stepped on the soul sword and flew at a speed of more than tens of thousands of kilometers per hour.
They crazily shuttled through the dark void space.
In just a few hours, they flew millions of miles.
Yang Dingtian's luck was very good.
In less than a day and a night, they actually flew to the end of the dark void space.
It seemed that this dark matter was either not big enough, or it was expanding too slowly, or it was expanding too late.
Previously, Yang Dingtian had flown for tens of millions of miles in that ghostly void space before he managed to escape.
This time, it was only one-tenth.
However, when Yang Dingtian created the space door and jumped out of the dark void space, he did not see the border of the Ancient Sea Serpent Empire. It was still an energy wall.
That's right, there was another dark void space in front of him.
Yang Dingtian created the space door again, jumped in, and flew with his near-Emperor-grade soul sword again.
This time, Yang Dingtian was not so lucky.
After flying for three days and three nights, they should have flown more than tens of millions of miles in this dark void space, but they still could not escape.
Yang Dingtian could not help but feel a little anxious.
It had been six days since they came out of the ruins of the Old Naga Empire.
At first, the situation was very smooth, but he did not expect to waste so much time in this dark void space.
Hopefully, this dark void space was not so big that it was infinite.
Yang Dingtian was not done complaining!
Something even worse happened!
Yang Dingtian's near-Emperor-grade soul sword suddenly became slower and slower, and finally came to a complete stop.
What, what was going on?
Yang Dingtian knew that a long time ago, the Naga royalty demon core of this soul sword was about to be exhausted.
Especially in the Buzhou Mountain domain, when Yang Dingtian stopped the new Demon King, Xu Yan Wentian, from approaching, he frantically released the Naga royalty sword soul. This was the final consumption of the demon core's energy.
However, this kind of dark void flying did not require much energy.
Even if there was a little bit of the Naga royalty demon core left, it would be enough to fly for many years.
However, he did not expect that it would run out of energy at this time.
After breaking the fossil of the Ancient Sea Snake Empress, the Naga royalty demon core's energy was almost completely exhausted.
What, what should he do?
This godforsaken space was constantly expanding. It was not advancing at all. Instead, it was retreating.
Moreover, in the battle with the Demon King, Xu Yan Wentian, the Naga royalty sword soul played a very important role.
This was because this was the only attack that Yang Dingtian could use.
Now, its profound qi energy had actually been completely depleted. It was simply too unlucky.
However, the problem now was more troublesome. The speed of the Mysterious Fire was only about ten thousand miles per hour, which was far from the speed of expansion of this dark void space. They would never be able to escape.
At this moment, the Naga Shuang suddenly turned into a ray of light and flew out of Yang Dingtian's space ring.
"Ao …" Then, she suddenly changed shape in the air and turned into a huge Naga that was hundreds of meters long.
"Whoosh whoosh whoosh …" The Naga Shuang threw Poissa and Vulture into Yang Dingtian's space ring.
Then, she opened her mouth and directly picked up Yang Dingtian.
"Whoosh …" Finally, she turned into a ray of golden light and flew toward the east at lightning speed.
This speed was actually not inferior to Yang Dingtian's Naga royalty sword soul.
It actually reached more than ten thousand miles per hour.
Naga was Naga, it was completely omnipotent!
Yang Dingtian's luck was not bad.
After a day and a night, they flew to the end of this dark void space and directly went against the energy boundary.
Yang Dingtian called out Poissa and Vulture from the space ring and then created a space door against the energy boundary.
The three of them, hand in hand, jumped over.
The moment Yang Dingtian jumped over the space door, the Naga Shuang directly turned into a ray of light and burrowed into Yang Dingtian's space ring.
In this way, the four of them all left the void space.
In front of them was the Ancient Sea Serpent Empire that had been swallowed by the dark matter.
There was an endless amount of dark matter everywhere.
Yang Dingtian took out the Eye of the Premier Naga, melted the dark matter, and kept flying toward the east.
It was still the Naga Shuang who complained that Yang Dingtian's speed was too slow.
Therefore, she took action again. With Yang Dingtian in her mouth and the Eye of the Premier Naga above her head, she melted the dark matter and flew at lightning speed.
Last time, it took Yang Dingtian five days to fly out of this endless dark matter.
This time, it took less than a day.
Naga Shuang flew back to the ruins of the Sea Serpent Empire's Magic Capital with Yang Dingtian.
After three to four months, Yang Dingtian once again returned to the palace hall of the Ancient Sea Serpent Empire.
He had finally returned with Naga. It would take at most two to three days to return to the human countries from here.
There was more than enough time to fight the Demon King.
The figure of the Sea Serpent Empress condensed and appeared, bowing to Naga Shuang!
