In this simulation, Jiang Yifeng accidentally left the Southern Region.
After leaving the Southern Region from Wan Jianlin, he did practice quietly for a while.
But this period lasted only fifty years.
After that, there were always strong winds, which made it impossible for him to continue practicing.
It seemed that even if he replicated this simulation, he would not be able to gain much simulation time.
He still needed to find a way to enter other large domains.
Jiang Yifeng felt that perhaps only the other large domains in the Nine Profound Realm could allow him to develop in peace.
However, after these two simulations, Jiang Yifeng came up with a bold guess.
Behind the cracks in the formation of the Death Desert, there were dragon corpses and dragon souls full of resentment.
Could this be the cemetery of the dragon clan?
And behind Wan Jianlin was a sea full of murderous aura, even manifesting into the shape of a white tiger.
Jiang Yifeng speculated whether this was also the resting place of the White Tiger clan.
After all, he knew from the simulation that the White Tiger clan had been completely wiped out, leaving only Wu Youdao's reincarnation.
If he thought even more boldly, could the cemetery of the Black Turtle clan be located behind the Endless Sea?
And was the Great Wilderness behind the Flame Valley the cemetery of the Phoenix clan?
Could it be that a powerful being in the immortal world killed the four great beasts, leaving only one in the Southern Region, while using their clan cemeteries to guard the cracks in the formation?
Jiang Yifeng kept pondering various possibilities.
Soon, he shook his head. Something wasn't quite right.
He had been to the Great Wilderness in the simulation but hadn't seen any Phoenix clan corpses. Apart from being desolate, it was inhabited by people, with no signs of a Phoenix cemetery.
Moreover, Bai Ruoxue had entered from the Endless Sea. If the Black Turtle clan's cemetery were located outside, she should have noticed it.
Additionally, Jiang Yifeng thought that if the powerful beings in the immortal world wanted to control these beasts, they wouldn't use such crude methods.
"There are still too few clues!"
Jiang Yifeng said to himself, deciding not to dwell on these questions any longer.
Instead, he shifted his focus to the rewards of this simulation.
There was no need to worry about the rewards this time.
He had obtained the "True Meaning of the Way of Killing (Entry)" through deep simulation.
The pseudo spiritual liquid (a pool) was also an excellent cultivation resource, but it was prohibitively expensive.
By now, Jiang Yifeng had discovered that all physical rewards seemed to require an exorbitant amount of energy value.
For example, a single spiritual stone cost 1 energy value.
When his cultivation was low and his consumption high, he thought it was affordable and exchanged many of them.
Now, in hindsight, it felt like a massive waste.
Hundreds of thousands of spiritual stones had cost billions of energy value, yet they had only helped him ascend a few minor realms.
Jiang Yifeng had even tried exchanging spiritual stones for energy.
But it wasn't worthwhile—he had once obtained them for 10,000 energy value per stone through the simulation.
Yet when exchanging them back, the value plummeted tenfold, with each stone worth only 1,000 energy value.
Ultimately, Jiang Yifeng abandoned the idea of choosing the pseudo spiritual liquid.
It wasn't cost-effective, and it highlighted the simulator's unscrupulous nature.
Currently, he had more than 6 billion energy value but couldn't even afford a pool of spiritual liquid.
So, Jiang Yifeng silently made his choices.
"I choose *Heaven Rewards Hard Work (Talent)* and *Desolation Fist (Minor Achievement).*"
[Ding, congratulations to the host for obtaining the talent "Heaven Rewards Hard Work," deducting 100 energy value. Remaining energy value: 6 billion.]
[Ding, extraction of *Desolation Fist (Minor Achievement)* successful. Deducting 100 million energy value. Remaining energy value: 5.9 billion...]
As the electronic sound of the simulator fell silent, Jiang Yifeng suddenly found himself in a mountain forest, repeatedly practicing the Desolation Fist.
Punch after punch, he practiced until he reached the state of minor achievement.
A few seconds later, Jiang Yifeng shook his head, confused.
What had just happened?
Why had this scene appeared when extracting combat skills this time?
Previously, when he extracted the Wind Chasing Art body technique, there had been no such sensation.
At this moment, the simulator's voice rang out.
[Ding, the host has practiced a combat skill too powerful for the current simulator level. It cannot be directly instilled and can only be upgraded through experience.]
[Hint: If the host upgrades the simulator, this problem will not occur.]
"Eh?"
The simulator had responded to his thoughts again.
Jiang Yifeng was speechless. Was the simulator intelligent or not?
At times, it seemed unintelligent, as it only answered at critical moments.
Yet when it seemed intelligent, it ignored him when called upon.
Nevertheless, Jiang Yifeng now understood why this extraction had differed from before.
It was harmless, though—how could he complain about an upgrade!
The thought of upgrading the simulator excited Jiang Yifeng.
After all, his simulations seemed stuck in a dead end.
No matter what he chose, it was challenging to leave the Southern Region, this forbidden land.
Unless his strength reached an immensely high realm, perhaps beyond the fairyland.
But achieving that realm was not something he could do in the short term.
Since his strength was advancing slowly, upgrading the simulator might provide new functions or talents to aid him.
With this in mind, Jiang Yifeng asked the simulator, adopting a trial-and-error approach.
"Simulator, what are the conditions for the next upgrade?"
[Ding, prompt: To upgrade this simulator to version 4.0, the host must reach the Nascent Soul stage or True Yuan realm, and 10 billion energy value is required.]
"Pfft!" Jiang Yifeng nearly spat out blood.
Was he being naive again?
Initially, he assumed the simulator needed a higher realm for its next upgrade.
After all, he had unlocked version 3.0 during the Golden Core stage.
But now, it seemed he had underestimated the cost and effort required.
Determined, Jiang Yifeng rushed out of his house without hesitation.
He went straight to his steward, Jiang Dafu, and instructed him to procure 10,000 tons of ore within a week by any means necessary.
The previous 10,000 tons of ore had earned him 6 billion energy points.
With another 10,000 tons and his existing 5.9 billion points, he could finally upgrade the simulator.
Seeing his young master's urgency, Jiang Dafu dared not refuse and agreed immediately, rushing off to make arrangements.
Once assured everything was on track, Jiang Yifeng heaved a sigh of relief.
He trusted Jiang Dafu's reliability—if the steward promised something, he would deliver.
With his affairs settled, Jiang Yifeng leisurely headed to Chunyan Tower to listen to music once more.
Time passed quickly.
A week later, Jiang Dafu delivered 10,000 tons of ore to the Jiang family's remote old house, as promised.
After dismissing everyone, Jiang Yifeng successfully exchanged the ore for another 6 billion energy points.
His total energy value now exceeded 11.9 billion!
Finally, Jiang Yifeng met the conditions to upgrade the simulator.
