This scene didn't last long, and the ball of light dove down at an extremely fast speed, finally disappearing into the Guardian Thunder Tower, becoming completely still.
"Hahaha, when luck comes, you can't stop it!"
Su Ran was overjoyed. The system truly understood him and allowed him to successfully strengthen the special building!
What the enhancement of the Guardian Thunder Tower meant was something only Su Ran knew, as waves of excitement surged in his heart, making it impossible to calm down!
"Brother Overturning Water, what happened?"
Banana looked confusedly at the iron plate on the ground, lost, not understanding why Su Ran was so excited.
The Guardian Thunder Tower was usually hidden beneath the ground, so it was no wonder Banana couldn't figure out the mystery. Even the three female elves were looking at Su Ran in confusion, hoping he would explain.
"My blueprint just now could strengthen the building, but it was random."
