Bab 1859: Improved Engine

Chapter 1859 - Improved Engine

As the light-blue loading bar filled, the analysis began to take more time to complete. Once the analysis reached 90% completion, each subsequent percentage took over a dozen seconds.

Don't tell me it's going to fail? Shi Feng couldn't help his growing nerves as he watched the loading bar.

Blank Subclass Designs generally had a 100% modification success rate, but as far as he knew, no one had ever tried to modify parts of a design.

The Subclass Design was a one-time use item, vanishing regardless of whether the modification succeeded or not. Nobody would take the risk of losing an opportunity to upgrade their subclass to the next rank.

Finally, after more than ten minutes, the modification finished.

And Shi Feng heard the sound of a system notification.

…

System: Congratulations! You have modified the Hell Tank's Engine and acquired the Dark-Gold ranked Hell Tank Engine Design.
