Year 1, nothing special happened Ye just continued to cultivate.Year 2 nothing spectacular happened again the system gave Ye Zai a warning "cultivation is good and all but Ye Zai is still human he needs to take a break and eat every once and a while".
Year 3 Ye Zai started to feel uncomfortable and started to spit blood he had broken through to the next stage but his body was to weak from not eating for 3 years.He was suffering three years of not eating while he was enduring backlash from his cultivation breakthrough.
The System said the hosts health Has dropped below minimum threshold now activating assisted breakthrough.The System then went into Ye Zai's body and helped him endure the breakthrough.
Then after he broke through his body, began to glow and he reached the immortal realm where if those who were not careful could destroy the several nations and just by walking could destroy entire cities.
Ye Zai then continued to cultivate, on year 100 He had reached the realm of deity child 2 stages from the realm of supreme deity, those who reached supreme deity stage could destroy the entire universe, including its concepts, unless they sealed their power, or were used in avatar to enter the world they would not be able to enter the world of mortals.
Ye Zai then exited the void and wanted to take a walk, but he forgot to hide his aura. As he walked every thing in the land surrounding was destroyed trees and mountains.Ye Zai realized he forgot to hide his aura he then concealed his aura and continued but not before a fellow immortal cultivator realized and started to follow Ye Zai.
The cultivator continued to follow Ye Zai into town an Ye Zai went into a restaurant the immortal following him wondering Whay Ye Zai went into a restaurant followed him inside and sat at the table beside him.Ye Zai then asked him "why have you been following me".
