After asking Xia Ning Chang carefully about the issue, Yang Kai realized that it was a coincidence that she managed to obtain that grey Qi.
It was just after Yang Kai had left Tong Xuan Realm, and Xia Ning Chang was feeling incredibly lonely. In order to pass the time, she could only sit in Nine Heavens Holy Land and refine pills every day.
She possessed the Sacred Spirit Medicine Body, so performing Alchemy was the same as cultivation to her.
While a large number of pills were refined, Xia Ning Chang’s own cultivation increased at a terrifying speed, without any kind of bottleneck at all.
After only a few years of hard work, she had become a Saint, catching up to Yang Kai’s cultivation when he had left.
Then one day, bored, she secretly ran out to travel alone and encountered this grey Qi in a hidden underground cave.
Since she collected that grey Qi, her cultivation pace became even more astonishing. Within just ten years, she broke through from the Saint Realm to the Saint King Realm, and another ten years later reached the Second-Order Saint King Realm.
Yang Kai was dumbfounded.
Such a terrifying cultivation speed was something that ordinary disciples of great forces on Shadowed Star may not be able to achieve it.
But in this barren Tong Xuan Realm, Little Senior Sister had accomplished such a feat.
The reason Xia Ning Chang had her current achievements was inseparable from that mass of grey Qi.
“After you obtained it, did you feel any discomfort?” Yang Kai asked seriously.
“There wasn’t any kind of discomfort per se,” Xia Ning Chang thought carefully, “It’s just that sometimes I would suddenly feel tired and become lethargic, not even wanting to think. Hehe, it was almost as if I suddenly became old.”
Yang Kai gently nodded.
“Junior Brother, is there some kind of issue with that thing?” Xia Ning Chang asked.
“I can’t say for certain whether it is a blessing or a curse,” Yang Kai shook his head slowly, a little worried.
“Then what is it?”
“I’m not certain, but I have a guess. If this guess is correct… Then, this is an astonishing opportunity for Little Senior Sister!” Yang Kai looked at Xia Ning Chang with scorching eyes and an excited expression.
This vague guess was enough to make his blood boil!
“Right, where did you obtain it, do you remember?”
“En,” Xia Ning Chang nodded.
“Take me there!” Yang Kai said, reaching out to embrace Xia Ning Chang’s slender waist, summoning his Star Shuttle, and shooting out like a bolt of lightning from Nine Heavens Holy Land.
Following the route Little Senior Sister laid out, Yang Kai flew through the air with her at great speed.
Only a day later, the pair arrived in the sky above a certain mountain range tens of thousands of kilometres long.
Xia Ning Chang’s memory was excellent, so even after more than twenty years, she still clearly remembered the exact spot she found the grey Qi that day.
Soon, the two landed in a secluded mountain valley and Yang Kai put away his Star Shuttle. Xia Ning Chang then led the way forward on foot.
Not long after, a deep and dark cave appeared before the pair, Xia Ning Chang pointed to it, and said, “Junior Brother, I was exploring this cave and found that thing at the deepest level.”
“Then let’s go in and take a look,” Yang Kai smiled. Emboldened by his strength, he took Xia Ning Chang’s hand and dove into the cave.
It was extremely dark inside, and the air was still, but not damp.
As soon as he entered the cave, Yang Kai’s brow rose slightly.
He felt the World Energy aura was incredibly rich in this cave!
Of course, it was only rich compared to other places on Tong Xuan Realm and could not be compared to other famous Cultivation Stars like Shadowed Star in the Star Field.
Nevertheless, this was still quite a rare find.
Moreover, the deeper they dove, the richer the aura became.
Yang Kai’s expression grew brighter as he became more and more certain his guess was correct. Otherwise, there would be no other explanation for the increasingly dense World Energy aura here.
This really was a Heaven-sent opportunity for Little Senior Sister! If that grey Qi was handled well enough, it would bring Xia Ning Chang unimaginable benefits, akin to allowing her to emerge from a cocoon and transform into a butterfly.
The two held hands as they descended step by step.
Suddenly, Yang Kai seemed to feel something and quickly paused.
At the same time, Little Senior Sister cheered happily, “It’s here, I can feel it!”
A mass of mysterious energy was approaching from the front at an extremely rapid speed. Yang Kai Divine Sense swept out and confirmed that the approaching energy was the same one he had extracted from Little Senior Sister a few days ago.
The grey Qi had sunk into the ground that day and returned to where it was originally located, but now that it felt Xia Ning Chang’s aura, it had come out on its own to meet her.
A moment later, the grey Qi arrived in front of them.
However, it did not dare leap out towards Xia Ning Chang directly and instead stopped about ten metres away from Yang Kai.
It felt threatened by Yang Kai!
“Junior Brother…” Xia Ning Chang looked at him and asked for his opinion.
“Let it come. I didn’t want to startle it that day, I just wanted to see what it was,” Yang Kai backed off and gave way.
Xia Ning Chang called out immediately, and as if it sensed her beckoning, the grey Qi flew past Yang Kai and sank directly into Xia Ning Chang’s chest, disappearing in the next instant.
Xia Ning Chang’s tender body shivered slightly as she let out a slight gasp.
A flash of golden light suddenly burst from Yang Kai’s left eye as a narrow and majestic golden pupil appeared, staring towards Xia Ning Chang.
Demon Eye of Annihilation!
