Lin Feng's Method

"The burden has increased!"

Lin Feng's heart sank. If the burden increased when rewinding time, normally, this meant that time had been rewound to a point when there's an entity with powerful strength.

Only then would Lin Feng's burden increase abruptly.

The burden of rewinding time was actually very, very small for Lin Feng. After all, it was not like reversing time, and the burden was not that extreme. However, if he had to rewind the time for an expert, such as a Two-star Supremacy, Three-star Supremacy, or even a Chiliocosm Sovereign, the burden would be very extreme.

If Lin Feng wanted to rewind the time for a Chiliocosm Sovereign, his internal chiliocosm domain would probably be at risk of collapsing as soon as he did. The power of such a powerful entity alone was enough to affect time. If Lin Feng wanted to rewind time for such a terrifying entity, there was no knowing how powerful his own strength had to be.
