In the normal upgrade, Lin Feng did not add any extra materials, mainly because he specifically consulted Chen Shanshan before upgrading.
The latter, out of concern that adding extra wolf bone materials might lead to a decrease in agility, opted for a normal upgrade.
The two upgrades increased the original twenty percent power bonus and fifty percent speed bonus to thirty percent power and seventy percent speed.
The power increase was not obvious, but the improvement in speed was significantly substantial.
Especially in high-performance mode, it can provide a one-hundred-percent speed bonus.
For the twenty-level Chen Shanshan, her original speed, after an outburst, could stably reach one hundred meters per second, and the hundred percent increase directly pushed it to two hundred meters per second!
Equivalent to a speed of seven hundred kilometers per hour.
