Although Immortal Qi was good, to most cultivators, it was just an illusion. It looked beautiful, but in reality, it could not bring about any benefits.
Cultivators were limited by their physiques, and their efficiency of absorbing Immortal Qi was very low. They could not unleash the full potential of Immortal Qi.
Even with Su Chen's strong physique, the amount of Immortal Qi he could absorb was very limited. If he purely used Immortal Qi to boost his cultivation and strengthen his physique, the effect would not be as good as the Purple Spirit Qi from the Dao Seed.
But, if he used Immortal Qi to nourish his soul, it would be different.
Firstly, Su Chen was a Spirit Master.
Secondly, Su Chen had obtained the Spirit Clan's secret Spirit Technique from the Spirit King's tomb, Immortal Soul Transformation!
Using Immortal Qi, Su Chen could transform his soul into an Immortal Soul bit by bit.
This was a qualitative change!
Su Chen originally planned to wait for the System to restart and buy a large amount of Heavenly Gold to absorb the Immortal Qi within it for cultivation. But now that he had the Immortal Qi within the Immortal Skull, he could directly use it to cultivate the Immortal Soul Transformation.
The Immortal Qi within the Immortal Skull was not too big, nor was it too pure. But, it was still much better than the Heavenly Gold.
The Fire Spirit Qi entered his sea of consciousness to circulate.
The Immortal Qi was used to nourish his soul and cultivate the Immortal Soul Transformation.
In an instant, Su Chen's cultivation potential was completely activated. He was immersed in cultivation.
Two days later, the green leaves on the Immortal Skull were all eaten clean by Su Chen.
Just these green leaves alone had allowed Su Chen's strength to improve by leaps and bounds, increasing by quite a bit.
Then, what kind of surprise would the remaining Immortal Skull bring to Su Chen?
But Su Chen was having a headache.
He did not mind the appearance of the Immortal Skull. After all, it was just a large piece of plant root and connective tissue. It was just that this thing was hard and Su Chen could not refine it. Could it be that he had to chew it raw?
Even though Yours Truly's teeth are very good, isn't this a little too crude and barbaric?
Forget it, I'll take a small bite to taste it first.
Crunch …
Su Chen took a bite and his expression froze.
It tasted like granite that had been frozen for ten thousand years.
Su Chen suddenly had some doubts.
Had this immortal skull been in the amber for too long and turned into a fossil?
However, Su Chen could clearly sense that the energy fluctuations contained within the skull were much denser than the green leaves.
Eat it, eat it. Even if it's a rock, it's still a rock formed from Saint medicine.
Crack! Crack!
Su Chen's teeth crunched as he chewed. He felt as if he was eating a lump of metal. Not only did it hurt his teeth, but it also pricked his tongue.
After chewing it to a suitable size, Su Chen simply swallowed it whole.
So hot!
A heat ten times more intense than before swept through Su Chen's entire body. Su Chen's entire body was instantly soaked in sweat. Before the sweat could drip down, it was evaporated by the high temperature. For a moment, white smoke curled up from Su Chen's body, as if he was about to ascend.
Su Chen felt as if his heart, liver, spleen, lungs, and kidneys were about to be burned to ashes.
However, the corners of Su Chen's mouth could not help but curl into a smile.
This was exactly the effect he wanted.
Boundless fire-attribute spiritual Qi burst out wantonly in Su Chen's body, as if a spiritual Qi typhoon was blowing.
He frantically absorbed the Spirit Qi, held his breath, and continued to cultivate.
Half a month passed in the blink of an eye.
Su Chen's body temperature had risen to a terrifying level. His silhouette was no longer visible. He was enveloped in a ball of golden flames, as if he'd turned into the sun. For a moment, his brightness even exceeded that of a soul lamp.
However, the light radiating from Su Chen had no effect on the demons of the Nightmare Dao. Even though his light grew brighter and brighter, the demons in the shadows around him were still restless.
The demons didn't care about Su Chen's cultivation. He was just a human ant from the Inextinguishable Tribulation. Even if he broke through the Immortal Tribulation, or even the Saint Realm, so what? He wouldn't be a threat to them at all.
As long as the soul lamp's power continued to weaken, it would be difficult to suppress them. Then, it would be time for them to launch a fierce attack.
"Pitiful ant. His death is near, but he's still struggling. How laughable."
"His perseverance is commendable, but he doesn't know what's good for him. He's doomed to fail."
"I quite like this little guy. His body contains a kind of potential that even I can't see through. It just so happens that my body is already broken. When the time comes, I'll take over this kid's body."
"You have no taste. This little guy's soul is the most delicious thing. When the time comes, don't try to fight me. Otherwise, don't blame me for not showing mercy."
"Look at how useless you guys are. As long as we break the seal and escape from the Mirage Sect, we won't have to worry about not having better food outside. I'm not interested in this mortal. The only thing that can interest me is a Heaven's Equal Realm Saint."
"I wonder if there are still divine kings in the outside world in this day and age. Looks like we'll have a great battle to our hearts' content."
"Tsk tsk, you remind me of the divine king who broke into the Nightmare Dao. His flesh is so delicious."
Just as the demons were whispering, the golden light on Su Chen's body suddenly erupted again, and the brightness increased by another level.
"He broke through!"
Complete Inextinguishable Tribulation!
He was only half a step away from the Immortal Tribulation.
The power of the immortal skull was a great surprise to Su Chen. He'd only refined half of it, but he'd already broken through to the Inextinguishable Tribulation. Once he absorbed the rest of the skull, he was sure to break through to the Immortal Tribulation.
Not only that, but after absorbing an enormous amount of fire spirit qi, the Great Solar Flame had reached the fifth level!
Its power had more than doubled.
Su Chen's soul was also strengthened by the immortal qi. When his soul power fluctuated, a wisp of ethereal immortal qi spread out.
He'd reached the peak of the ninth-stage Soul Master realm!
Was this the power of the sacred medicine? In just twenty days, Su Chen's overall strength had risen to a whole new level. If he'd cultivated step by step, Su Chen would've needed several years or even decades to reach this level.
It was no wonder that powerful cultivators yearned to explore all kinds of opportunities.
The stronger one was, the harder it was to break through. If one wanted to improve themselves quickly, they had to use all kinds of rare treasures.
Cultivating step by step was like working for a salary. You wouldn't starve to death, but your future was bleak.
If you wanted to get rich, you had to go out and fight.
Whoosh!
The soul lamp flickered again.
Su Chen waved his hand and poured his soul power into the soul lamp.
Fortunately, after cultivating the Immortal Soul Transformation, his soul power recovery rate had greatly increased. Now, the soul lamp was relying on Su Chen's soul power to forcibly support it.
However, this wasn't a long-term solution. Su Chen didn't know how long the soul lamp could last.
It had been four months since he'd arrived at the Nightmare Island. In a month, the system would restart. In two months, Su Chen would be able to leave this damned place.
Could he hold on?
Even if he couldn't, he had to. In Su Chen's dictionary, there was no such thing as admitting defeat!
