At this moment, in Qi Yuan's perception, it felt as though an unparalleled master was personally transmitting profound teachings to him.
A flood of unfamiliar but incredibly profound knowledge continuously poured into his mind, seamlessly integrating into his memory.
As this realization surged within him, it was as if a fog had lifted from Qi Yuan's heart, and an overwhelming sense of enlightenment instantly filled his mind.
It was a sudden, deep understanding of the 'rules'!
"This is the domain…" Qi Yuan unconsciously traced his fingers in the air in front of him.
Crackling~~~
Purple electric sparks appeared, dancing at his fingertips before rapidly spreading out in all directions.
The electric snakes twirled, and thunderbolts crackled everywhere!
In just a moment, his entire cultivation cave was transformed into a thunder domain filled with destructive energy!
Standing at the center of the thunder domain, Qi Yuan opened his eyes. In the depths of his gaze, a faint purple electric glow flickered.
"Return!"
The next second, his five fingers clenched into a fist.
Immediately, the vast thunderbolts contracted as if devoured by a black hole, disappearing in an instant.
Only a few residual sparks remained, dancing at the tips of his hair, casting a faint purple glow in the depths of his pupils.
"I never expected that the system would even return something like a 'domain'!" Qi Yuan thought, feeling like he had just been hit by an enormous blessing. His lips unconsciously curled into a smile.
At first, he only wanted to test another function of the system, but this was a surprise beyond his expectations!
What he had previously taught Cang Fan mostly consisted of basic knowledge that planetary stage cultivators should be familiar with.
As for the laws and domains, they were common concepts in the universe, with no deep, specialized content involved.
Yet, under the 400x return multiplier, these very basics had turned into insights related to the 'Thunder Domain', a topic that many stellar-level geniuses wouldn't even comprehend!
It was no exaggeration to say this was like "eating grass and squeezing out milk!"
"Now this is more like it! If, after teaching, the return is only the same knowledge I already possess, then that option would be pretty useless!"
Qi Yuan's eyes shifted, and based on the two previous returns, he had begun to form some understanding of the system's return mechanics.
For example, the first time, he had given the 'Earth Soul Liquid' as a gift, and it returned 'Wood Yajing', a higher-quality resource.
The second time, when he taught 'Planetary-level cultivation experience', the system had returned a highly advanced concept: 'Thunder Domain', something even many stellar-level geniuses wouldn't master.
From this, it seemed that the system's return items weren't just a matter of adding up in quantity. It involved quality upgrades as well.
If that's the case, compared to simply gifting items, the 'teaching cultivation experience' option might actually be the more valuable one.
Perhaps it wasn't clear yet, but as Qi Yuan's cultivation level increased, such as when he reached the bottleneck of breaking through to the Master of the Universe, or even the Strongest in the Universe, he could potentially break through those immense barriers with a single lesson.
Just thinking about the potential rewards was enough to drive someone mad with excitement!
"It seems like I'll know for sure once I try a few more times." Qi Yuan mused to himself.
"For now, though, it's best to focus on my own cultivation!"
Qi Yuan sat in the cave for a long time, gradually calming the excitement and restlessness that had surged within him. Then, without wasting any more time, he immersed himself back into his rigorous training.
What pleased him was that, with the addition of the domain, his control over his body had undergone a significant improvement!
This greatly enhanced his ability to control both the explosive force of 'Nine Radiant Heaven Saber' and the resonance of multiple energies during combat.
His progress in 'Nine Radiant Heaven Saber' also became increasingly rapid.
In just one month, he had completely mastered the seventh level of the Nine Radiant Heaven Saber's techniques, directly increasing his power output by 21 times!
When the new month's return opportunity arrived, he again chose to 'teach cultivation experience' as the gift for the return.
However, this time, the result was a bit disappointing.
It was possible that the gap between this and the last return was too short. Cang Fan hadn't even finished digesting the previous gains, so he didn't ask any particularly insightful questions.
Qi Yuan spent a lot of effort explaining, but in the end, he didn't even trigger a critical hit reward.
The return multiplier was only 8x, and it only returned a "Mastered Planetary-level cultivation insight," giving him a deeper understanding of planetary-level cultivation.
This result was a far cry from the amazing rewards from the previous two returns!
However, this experience taught Qi Yuan that the system's critical hit rewards weren't so easy to trigger.
The reason the first two critical hits had triggered was that the 'gifts' had been something completely new to Cang Fan.
Both the Earth Soul Liquid and the insights into domains and laws were things Cang Fan had never encountered before. Naturally, they had a much greater impact on him.
But when the same content was used again, Cang Fan, having already experienced the initial "shock," was much less likely to be deeply moved.
It seemed that, in order to trigger a critical hit, Qi Yuan either needed to constantly change the 'gifts', maintaining a sense of surprise for Cang Fan, or he could change disciples, allowing them to experience periods of "disappointment" before they would truly appreciate the value of their teacher's guidance.
"It looks like the system's two return options should be balanced and used wisely," Qi Yuan concluded.
In the following time, Qi Yuan continued his cultivation while also further experimenting with the system's functions.
He used the 'Thunder Saber Body Forging' technique to absorb 'Wood Yajing' and recover, sticking to a routine.
When the return opportunity for the next month arrived, he tried using different 'gifts' to maximize his returns.
In the fourth month, he used the Wood Yajing given to him by the Thunderstorm Star Master as a gift, which triggered a critical hit reward, giving him a Dragon Vein Fruit.
After secretly consuming it, his cultivation breakthrough took him to Stellar Level 4.
In the fifth month, he used 3 kilograms of Earth Soul Liquid as the gift, barely triggering a 10x critical hit, which gave him 480 Wood Yajing.
In the sixth month, after a three-month gap, he again chose to 'teach cultivation experience' as the return trigger.
This time, under Qi Yuan's meticulous guidance, Cang Fan seemed to make good progress, triggering a 50x critical hit, and Qi Yuan received insights into the Thunder Domain once again.
After assimilating these insights, Qi Yuan's understanding of the Thunder Domain deepened further. He was now on the verge of breaking through to the second layer of the domain.
And just as he was deeply immersed in his peaceful cultivation, his routine was suddenly interrupted.
Before the magnificent castle of the Thunderstorm Star Master, Qi Yuan, who had just disembarked from the spaceship, curiously transmitted a question to Old Wu, who stood beside him:
"Old Wu, is there a task this time that the Master is calling us for?"
"It's not really a task," Old Wu responded through a transmission. "The Master is returning to his family, and most of the personal guards will accompany him."
"Family?" Qi Yuan was taken aback. "Is that why we're leaving Thunderstorm Star?"
"Yes." Old Wu nodded, a deep sense of reverence in his gaze.
"The Master's ancestral home is on Lanka Star, where more than half of the Ortega family's elites reside. There are even Domain Lords there. It's a prosperous planet renowned throughout the entire Eternal Starfield!"
Listening to Old Wu's introduction, a peculiar glint flashed in Qi Yuan's eyes.
"I wonder if I'll have a chance on Lanka Star…"
