Yang Dingtian loudly said, "Seniors of the Netherworld Sea, Yang Dingtian has come to visit!"
There was only silence. There was no response.
"Seniors of the Netherworld Sea, Yang Dingtian has come to visit." Yang Dingtian loudly shouted again.
Still no response.
"Seniors of the Netherworld Sea, Yang Dingtian has come to pick up my wife, Yanyan Ximen, please show yourself." Yang Dingtian shouted.
Still no response.
Yang Dingtian suddenly frowned.
Yanyan had knelt on the silver beach for seven days and seven nights. When she was about to die, the people of the Netherworld Sea appeared and took her and Yang Dingtian in.
Now, it was absolutely impossible for Yang Dingtian to kneel for seven days and seven nights. Moreover, he didn't have the time.
Yang Dingtian said, "Seniors of the Netherworld Sea, in order to save me last time, you wasted a Naga's Xuan Vein crystal, which was five inches long.
This time, I brought a fresh Naga's purple Xuan Vein, which was one foot long, to repay my debt. "
One must know that purple was one level higher than red.
Moreover, one was five inches, while the other was one foot long.
One was a crystal, while the other was a fresh Xuan Vein.
Therefore, Yang Dingtian returned Yang Dingtian to the Netherworld Sea, which was more than ten times what the Netherworld Sea gave him before.
Of course, the Naga's Xuan Vein that Tantai gave to Yang Dingtian was three feet long. Yang Dingtian used one foot to repay the debt. One foot was intended to be used on Yanyan, and the last foot was used on himself.
If the holy water still couldn't save Yanyan's Xuan Vein, then this foot of Naga's Xuan Vein should be able to heal Yanyan's Xuan Vein.
Of course, the one foot long Xuan Vein that Tantai gave was a whole one. There was almost no weapon in the world that could cut off the Naga's Xuan Vein without destroying its energy.
Fortunately, Yang Dingtian possessed the Mystic Flame and could silently sever the three feet Mystic Vein into three sections in an instant.
To be honest, if Yang Dingtian were to use all of the purple veins from the Naga Clan on himself, he might be able to break through to the Revered Martial Artist level.
However, he owed Yanyan so much. How could he be so selfish and use this treasure on himself?
Just now, the Netherworld Sea had ignored Yang Dingtian's call from beginning to end.
Now that Yang Dingtian had used such a precious treasure to lure them, he did not believe that the people of the Sea of Hades would not show themselves.
A foot of Naga's purple Profound Veins was enough to move anyone in this world, even the Netherworld Sea.
However, after Yang Dingtian shouted, there was still silence.
Yang Dingtian directly took out a jade box from his bosom, raised it high in the air and said, "Everyone from the Netherworld Sea, I am willing to use a foot of purple Naga Clan's profound veins in exchange for the freedom of my wife, Ximen Yanyan. Please show yourself."
Suddenly, a gust of wind blew past.
The mirror-like Netherworld Sea surged.
However, there was still no response!
Yang Dingtian did not believe that the Netherworld Sea would not be moved by him taking out such a precious treasure.
However, no one had appeared yet. He was afraid that they had other intentions.
The people from the Netherworld Sea had never been good people.
Otherwise, there would not be a debt to the Netherworld Sea that could not be repaid in ten lifetimes.
Next, Yang Dingtian shouted three more times, but no one responded.
Yang Dingtian frowned and said, "If you don't show yourself, then I will enter the Netherworld Sea myself."
Suddenly, a cold wind blew past, as if it brought along a burst of disdainful ridicule.
It was as if it was mocking Yang Dingtian. If there were no people from the Netherworld Sea leading the way, no one in this world could enter the Netherworld Sea, and no one knew where the Netherworld Sea was.
Yang Dingtian actually said that he wanted to come in himself. It was ridiculous.
… …
Yang Dingtian naturally did not know where the Netherworld Sea was. However, ever since he went to the Celestial Red Sea and Five Elements Hall Secret Realm, Yang Dingtian had a deeper understanding of the Netherworld Sea.
"Then I will offend you. I will barge into the Netherworld Sea myself." Yang Dingtian said loudly.
He pretended to stuff the jade box containing the Naga Race's Xuan Veins into his clothes, but in reality, he stuffed it into his spatial ring.
Then, Yang Dingtian unfolded the Empty Spirit Profound Wings and flew into the air. He circled above the sea surface, looking for the entrance to the Netherworld Sea.
This jade-like sea surface did not have any abnormalities at all. Looking from the sea surface, it was impossible to tell where the entrance to the Netherworld Sea was.
Yang Dingtian only knew that the Netherworld Sea was at the bottom of the sea. Moreover, it was a completely different world. There was even a sky and an island there.
It was as if it was another small world.
Suddenly, Yang Dingtian descended from the sky and dived into the sea.
The water here was very calm. There were almost no waves or flow. It was completely clear to the extreme. It really did not seem like the water of the sea.
Moreover, there were no living creatures in this sea. No matter if it was fishes or prawns, there was not even any aquatic plants or corals.
Yang Dingtian kept diving and diving, and very quickly, he reached the bottom of the sea.
It was not different from the ordinary bottom of the sea. The bottom of the sea here was completely flat and smooth.
Moreover, every inch and corner was exactly the same. There was no difference at all. There was not a single place that looked like the entrance to the Netherworld Sea.
Yang Dingtian pulled out his youngling sword and stabbed down at the smooth bottom of the sea.
Yang Dingtian's youngling sword could be considered as the world's sharpest and hardest treasure sword. It was almost indestructible.
However, this stab with all his strength was unable to pierce through the bottom of the sea.
It was not because the bottom of the sea was very hard. Rather, it was because when he stabbed it, it was immediately rebounded.
As a result, Yang Dingtian used all the profound qi in his body to hack down.
The bottom of the sea was still undamaged. No matter how much power Yang Dingtian hacked down, it was all rebounded back. Yang Dingtian's chest immediately turned over and over. He almost vomited blood.
The bottom of the sea was not some kind of hard substance, but some kind of energy substance. No matter how much power was hacked down, it would all be rebounded.
Therefore, no matter how sharp the sword was, it was useless.
If the sword was useless, then what about the Profound Flame?
After Yang Dingtian slightly hesitated, he closed his eyes and clasped his hands together. Suddenly, a sharp Profound Flame blade emerged.
"Go … …" Yang Dingtian suddenly used his profound qi.
Suddenly, the Profound Flame turned into a flaming blade and stabbed towards the bottom of the sea.
The Profound Flame was indestructible. It directly used energy to break energy.
"Boom … …" When the Profound Flame Flaming Blade was hacked down, Yang Dingtian felt a sudden tremor under his feet. The sea water surged.
However, that was all. The bottom of the sea was still undamaged. The energy of Yang Dingtian's Flaming Blade was completely like mud sinking into the sea.
Yang Dingtian no longer acted rashly. Instead, he closed his eyes and sat cross-legged on the bottom of the sea. He recalled every scene in the Netherworld Sea that day.
He clearly remembered that when he was in the Netherworld Sea, there was a sky and a sun above his head. It felt exactly the same as on the ground.
However, the Netherworld Sea was indeed at the bottom of the sea.
And the bottom of the sea was completely filled with energy substances.
That meant that the Netherworld Sea was under the sea.
The sea water was absolutely transparent. Therefore, when he was in the Netherworld Sea, the sun and sky he saw were separated by a layer of absolutely transparent sea water.
Of course, if it was on Earth, light would not be able to pass through such deep sea water without any damage.
However, this seawater was completely different.
If the Netherworld Sea was only separated by a layer of seawater, this layer of the sea floor was only filled with energy substances and did not have a physical body.
And the seawater would not flow down. That meant that there was a different gravitational field under the sea, just like the Five Elements Hall Secret Realm.
That meant that Yang Dingtian and the small world of the Netherworld Sea were only separated by a layer of energy field.
However, he was completely unable to pass through this powerful energy field.
However, the people of the Netherworld Sea could enter and leave as they pleased. That meant that there was still an entrance.
But other than the people of the Netherworld Sea, no one else could find the entrance to this energy field.
The sea surface here was at least a few hundred miles in size.
If the entrance to the energy field was completely unfixed, then no matter how high an ordinary person's cultivation was, they would not be able to find the entrance.
Of course, Yang Dingtian would not be able to find it either.
Then, Yang Dingtian's heart lit up. Perhaps he had a way.
Closing his eyes, Yang Dingtian summoned the Mystic Fire in his sea of qi.
Suddenly, the Mystic Fire in his sea of qi flared up.
Then, the Mystic Fire suddenly split into countless resentful spirits.
Yang Dingtian's Million Spirit Demonic Fire contained hundreds of millions of resentful spirits. Each resentful spirit had an independent soul.
Hundreds of millions of resentful spirits could cover hundreds of miles of the sea floor and there would be more than enough of them.
"Go …" Yang Dingtian ordered.
Instantly, countless resentful spirits separated from the Mystic Fire and rushed to every inch of the sea floor.
An army of hundreds of millions of resentful spirits was enough to fill every inch of the sea floor.
Then, Yang Dingtian closed his eyes and sensed the countless resentful spirits.
Instantly, Yang Dingtian's mind was filled with the fluorescence of resentful spirits. They were densely packed and were even denser than the stars in the sky.
The sea floor here was extremely calm. Hence, the resentful spirits behind the wall cloth were also floating there peacefully.
However, there would definitely be energy surging at the entrance to the Netherworld Sea.
And these resentful spirits were the most sensitive and the slightest energy bodies.
Just like countless dust particles floating in the air, as long as there was a slight breeze, the dust particles would dance and undulate.
Indeed!
Yang Dingtian found it. 120 miles away from the northeast corner, the resentful spirits were surging up and down uneasily.
That's right, that was the entrance. Hence, the energy field was not calm and caused the resentful spirits to surge.
Instantly, Yang Dingtian hurriedly chased after it.
Indeed, this energy entrance was constantly moving. Furthermore, it seemed to be moving without any pattern. It was completely random.
No wonder other than the people of the Netherworld Sea, no one else could find the entrance. This kind of erratic entrance was less than two feet in diameter. In an area of hundreds of miles, even immortals could not find it.
If Yang Dingtian did not have hundreds of millions of resentful spirits, even if he became a Great Grandmaster, he would not be able to find this entrance.
Yang Dingtian swam quickly and chased after this entrance.
Soon, he caught up to the entrance where the energy was unstable and rushed in.
"Whoosh …"
Instantly, as if he had entered a whirlpool, Yang Dingtian was directly sucked in.
After being sucked in, Yang Dingtian passed through a layer of empty energy field and fell down.
The scenery below was very familiar. It was a beach, a golden beach.
That's right, below was the Netherworld Sea.
The Netherworld Sea and the seawater above were separated by a layer of anti-gravity energy field.
In this world, no one could find and enter the Netherworld Sea. However, Yang Dingtian did it.
At this time, Song Yu was looking at Yang Dingtian who had barged into the Netherworld Sea with a face full of shock.
