Chapter 551: One Month Later

```

Logically speaking, Ye Feng's current study of the "Time Deceleration Rule" should be at least twice as difficult as the "Time Acceleration Rule".

After all, the Time Acceleration Rule can still be referenced through the World Tree Body, whereas Time Deceleration could only rely on Grand Elder Lu Ming's teaching.

According to Ye Feng's initial estimate, it should have taken at least two months to get started.

But in the end, he had successfully begun after just 25 days.

The reason for this wasn't that Ye Feng's talent had improved by much, but rather it was due to his continuous understanding of the Time Acceleration Rules.

Eventually, he had elevated the Time Acceleration Rules from the Rule Realm to the Domain Realm.

Under normal circumstances, the Domain's Time Acceleration Ability could maintain a 10 times acceleration for him.
