If there was no holy water, Yang Dingtian would definitely not be able to withstand the profound energy surging out from the golden demon core. This profound energy was simply too powerful and overbearing.
However, it was completely different when the demon core was placed in the holy water. This incomparably powerful profound energy directly seeped into the holy water, and then into Yang Dingtian's profound veins. The impact was immediately reduced by a lot.
However, it was still very painful because the profound energy that poured in was simply too powerful, too much.
It felt as if Yang Dingtian's profound veins were about to explode.
Yang Dingtian closed his eyes and circulated the Qi Refinement Art, frantically devouring this incomparably powerful profound energy.
What surprised Yang Dingtian was that this profound energy was not completely pure.
However, it did not seem to have any attributes, whether it was Yin or Yang. Of course, it was not fire or ice, etc.
This profound energy carried a very, very peculiar aura. At least, this profound energy was golden in color.
Whether Yang Dingtian used the Profound Fire to refine it, or the Yin Yang Qi Transformation Art, he was unable to make this profound energy become completely pure.
However, this profound energy could completely enter the Qi Sea and be used to raise his cultivation.
Merely an hour later, a golden light flashed in front of Yang Dingtian's eyes.
Then, all of his consciousness and everything turned into nothingness.
He was very familiar with this feeling because he was about to break through and level up.
But this time, it was different from before, when there was nothing but emptiness.
When he was in the void, it was as if something different, different, and mysterious was crazily pouring into Yang Dingtian's mind.
Yang Dingtian wanted to search, wanted to capture an image, but it disappeared without a trace.
Furthermore, when he entered the void, Yang Dingtian could not control his thoughts at all, as if this brain did not belong to him.
After a short period of nothingness, this mysterious image that poured into Yang Dingtian's mind immediately stopped.
And Yang Dingtian's Qi Sea was currently empty.
However, the slightly strange thing was that Yang Dingtian felt that the inner wall of his Qi Sea was actually golden. That's right, it was actually golden.
It was really too strange. The profound qi that was pouring in was golden, and the inner wall of the Qi Sea was actually golden as well.
However, from this, Yang Dingtian finally confirmed that although the Sea of Qi was in the lower abdomen, it was a virtual space.
Furthermore, the Qi Sea was completely formed from refined profound energy.
It was no wonder that ordinary battle Xuan Qi could be filled to the brim within four to six hours after entering the Sea of Qi.
As for the refined Xuan Qi, it would be compressed by a hundred times after entering the Sea of Qi.
When the cultivation Xuan Qi filled the entire Qi Sea, it immediately exploded.
At this time, the cultivation Xuan Qi inside did not disappear. Instead, it directly merged with the Qi Sea and became a part of the expanded Qi Sea.
Moreover, both combat and cultivation Xuan Qi were in the Sea of Qi.
However, the two spaces were completely independent and did not interfere with each other.
Even if the battle profound energy filled the energy sea, it would not prevent the cultivation profound energy from entering, and vice versa.
…
After breaking through and leveling up, Yang Dingtian was already a seven-star Martial Ancestor.
After that, the golden profound energy continued to crazily surge into Yang Dingtian's Xuan Meridians before gathering and entering the Sea of Qi.
After all the profound energy entered the Sea of Qi, it was directly compressed by a few hundred times and gradually filled the Sea of Qi.
Yang Dingtian also realized that as his cultivation level increased, the degree of compression of the profound energy that entered the Sea of Qi increased.
At the beginning, the cultivation profound energy that entered the Sea of Qi was only compressed by a few dozen times. Later on, it was compressed by a few hundred times.
In other words, as one's cultivation level increased, the amount of profound energy required to break through the Sea of Qi would increase exponentially. The firmness of the Sea of Qi would also increase greatly.
Of course, the cultivation time required to break through one level was even longer.
Previously, it was said that even a martial artist with eighth-grade Xuan Meridians would need about two years to break through from a six-star Martial Ancestor to a seven-star Martial Ancestor.
However, Yang Dingtian had the Nine Yang Meridians, the Yin Yang Qi Transformation Technique, and the Million Spirit Demon Fire. He only needed two to three months and his cultivation speed was more than ten times that of others.
On the other hand, absorbing the profound energy from the Naga royalty demon core only took about an hour.
Of course, this was because Yang Dingtian was already a mid-grade six-star Martial Ancestor. In this hour, it was equivalent to breaking through half a level.
…
The process of breaking through from a seven-star Martial Ancestor to an eight-star Martial Ancestor had undoubtedly slowed down.
The energy from the Naga royalty demon core was still incomparably powerful, but the amount of profound energy required to break through from a seven-star Martial Ancestor to an eight-star Martial Ancestor was simply too much.
Compared to breaking through from a six-star Martial Ancestor to a seven-star Martial Ancestor, it was a completely multiplied increase.
Furthermore, as Yang Dingtian refined the profound energy into his Sea of Qi, he also felt his own body and was surprised to find that.
When countless profound energy entered the Sea of Qi through the Xuan Meridians, there were many golden-purple photons that remained at the Xuan Meridians and then seeped into the Xuan Meridians.
These golden Xuan Meridians were mixed with the purple Naga royalty and were actually transforming his Xuan Meridians.
However, he had the Nine Yang Meridians and there was almost no room for transformation.
Just like this, countless profound energy entered his Xuan Meridians and after being compressed by a few hundred times, flowed into his Sea of Qi.
His empty sea of qi rose little by little.
Two hours passed.
Four hours passed.
Four hours later!
Finally, the golden-yellow profound energy once again filled Yang Dingtian's Sea of Qi.
Yang Dingtian's Sea of Qi began to expand and expand.
Previously, because the Sea of Qi was colorless, Yang Dingtian could only feel it expanding, but he couldn't see it expanding.
This time, he could see it clearly. The golden-yellow Sea of Qi began to tremble, as if it was a bomb that was about to explode.
"Boom …"
With a flash of golden light, everything entered nothingness.
Yang Dingtian's body, his mind, and his spirit had completely entered nothingness.
He broke through again and became an eight-star Martial Ancestor!
Similarly, at this time, countless information, mysterious and clear, crazily poured into Yang Dingtian's mind.
However, Yang Dingtian was still completely unable to capture a single image. He could only helplessly watch as the information crazily poured into his mind.
The breakthrough was over!
Everything around him gradually returned to normal and Yang Dingtian gradually regained consciousness.
The color of the Sea of Qi had obviously become more golden-yellow, and it was empty again.
Then, countless golden-yellow profound energy poured into the profound veins again. After being compressed by hundreds of times, it flowed into the Sea of Qi again.
…
Two hours.
Four hours.
Six hours.
Eight hours.
Eight hours later, the golden-yellow profound energy once again filled Yang Dingtian's Sea of Qi.
Yang Dingtian's Sea of Qi expanded again, expanded …
It expanded to the extreme.
"Boom …"
With a flash of golden light, everything entered nothingness again.
Yang Dingtian successfully broke through again and became a nine-star Martial Ancestor.
In the short period of nothingness, countless information still crazily poured into Yang Dingtian's mind.
Perhaps, this was the soul memory of the Naga royalty. Who knew?
…
At this time, Yang Dingtian was already a nine-star Martial Ancestor.
Sixteen hours had passed since he started cultivating, which was sixteen hours in total.
He had promised Miejue Toutuo that he would only borrow it for one day.
There were only eight hours left.
Just now, Yang Dingtian had spent eight hours to break through to the nine-star level.
The time needed to break through to the Martial Venerable level from the nine-star Martial Ancestor level was probably double.
Yang Dingtian only had eight hours left. It was obviously impossible for him to break through to the Martial Venerable level.
Of course, Yang Dingtian could break the contract and return the golden Demon Core to Miejue Toutuo after he had completely devoured the profound energy in it.
However, a man could not live without integrity!
Moreover, Miejue Toutuo had lent him the Demon Core, which was already a great kindness. How could he break the contract again?
In the face of an untrustworthy person, it was pedantic and stupid to pay attention to credibility.
However, in the face of a person who was indebted to him, it was shameless to go against credibility.
Therefore, Yang Dingtian had to change his method. Otherwise, he would not be able to break through to the Martial Venerable level within eight hours.
Yang Dingtian took a deep breath.
There was only one way, which was to shorten the time for profound energy to enter the Sea of Qi and reduce the loss of profound energy in the process of passing through the profound veins.
The method was to swallow the entire Naga royalty's Demon Core into his stomach and use profound energy to force it into his lower abdomen, where it was closest to the Sea of Qi.
That way, shortening the distance was nothing.
The most important thing was to reduce the loss of profound energy in the circulation of profound veins throughout the body.
However, this was extremely dangerous.
Such powerful profound energy would first flow through the entire body's profound veins and then enter the Sea of Qi. There would be a huge buffer.
Now, Yang Dingtian wanted to swallow it directly into his stomach and release profound energy from the side of the Sea of Qi. He wanted to swallow it directly into the Sea of Qi.
This was too terrifying. This was using less than ten percent of the profound veins to swallow the same amount of profound energy as before.
There was no need to talk about the extreme pain. It was very likely that part of the profound veins would explode and even Yang Dingtian's Sea of Qi would shatter.
However, there were two reasons why Yang Dingtian dared to take such a risk.
One of the reasons was that he was in the Holy Water.
Secondly, all the profound veins in his body had been transformed by the Naga royalty's purple profound veins.
Even if it couldn't upgrade the grade of his profound veins, it could at least make them tougher.
Gritting his teeth, Yang Dingtian immediately made a decision!
Fight it out …
Yang Dingtian took out a cup of Holy Water from his spatial ring and placed the Demon Core in it. Then, he swallowed the Demon Core with the Holy Water.
Then, he used profound energy to quickly force the Demon Core to the vicinity of his lower abdomen.
"Ah …"
The moment the Demon Core entered his stomach, Yang Dingtian almost cried out in pain.
It was really painful to the extreme. It was completely indescribable.
It was as if a bomb had directly exploded in his stomach.
After the extreme pain, Yang Dingtian felt that his stomach was completely numb, as if the entire stomach didn't belong to him at all.
That kind of pain directly made Yang Dingtian faint.
"Pfft …" A mouthful of blood suddenly spurted out.
Then, the meridians in Yang Dingtian's entire body shattered inch by inch at a speed that could be seen with the naked eye.
Countless amounts of blood surged out from the countless cracks.
That small portion of his profound veins still couldn't withstand such powerful energy and directly shattered inch by inch.
At this time, Yang Dingtian had become incomparably shocking. Countless cracks appeared all over his body, making him look like a ghost.
Even though he knew that the consequences would be severe, he didn't expect it to be so terrifying.
Yang Dingtian didn't care. He frantically operated the Qi Refining Art, guiding the incomparably powerful profound energy into his Qi Sea.
At this time, even under extreme pain, Yang Dingtian still had to maintain his rationality and use the shortest time to guide the profound energy into his Qi Sea. Otherwise, the consequences would definitely be Yang Dingtian's body and bones shattering.
Finally, after the profound energy entered his Qi Sea.
Only then did the powerful energy of the Demon Core stop rampaging through Yang Dingtian's body.
Even though it was still painful as if countless red-hot knives were stirring in his stomach, it was much better than before. The pain just now directly made Yang Dingtian's eye sockets crack.
Next, under the effect of the holy water, Yang Dingtian's cracked body finally gradually healed and recovered.
Then, everything returned to normal.
In the process that was like a knife twisting, countless powerful golden profound energy crazily poured into Yang Dingtian's Qi Sea.
Two hours.
Four hours.
Three and a half hours.
Yang Dingtian's Qi Sea was once again filled with golden profound energy.
The Qi Sea began to expand, expand, expand …
"Boom …" A golden light burst out.
Everything entered nothingness.
Countless mysterious information once again crazily poured into Yang Dingtian's mind.
And the strange thing was that the time of nothingness this time was exceptionally long.
In the past, the time of nothingness after breaking through was at most four or five seconds.
This time, it was a full few minutes.
It was as if endless information crazily poured into Yang Dingtian's mind, causing that moment, Yang Dingtian's spirit and mind seemed to be about to turn into ashes.
A few minutes later.
The nothingness stopped.
Everything around him began to gradually recover!
And Yang Dingtian had officially broken through to Martial Venerable!
In the almost hellish pain, Yang Dingtian finally succeeded in breaking through to Martial Venerable within the allotted time!
