Su Xing slightly shook his head.
The third layer of the Zhengyi Submission Decision required consuming the qi of the four seasons.
Only on the days of the start of spring, summer, autumn, and winter could cultivation progress rapidly.
On ordinary days, though progress was possible, it was far slower than on those four days.
Therefore, advancing to the third layer of the Zhengyi Submission Decision demanded a lot of time and effort.
"At this pace, I might need several simulations... or hundreds of years in an immersive simulation to master the third layer?"
Su Xing slightly shook his head. Since the Zhengyi Submission Decision could not currently progress to the third layer, he decided to go all out for the Yin Fire Calamity instead!
There were forty years remaining in the simulation, enough time to pass through the Yin-Yang Fire Calamity and break through to the Earth Immortal realm!
With this thought, Su Xing looked at the simulation panel.
