The only drawback was that the Upgrade Card took too long, and he would be completely cut off from the world during the upgrading process. It would be troublesome if something happened during that time, and he could not make a move.
Lu Zhou hesitated. He did not know if he should use the Upgrade Card or not.
He sensed the situation in Fragrant Valley. Then, he looked at the building he was in. It was simple and crude and stood in an open space, making him feel insecure.
Lu Zhou looked at the description for the Upgrade Card.
[After using the Upgrade Card, it would take 100 years to upgrade the system.]
"..."
Following that, a system notification rang in a timely manner.
"Ding! Would you like to use the Upgrade Card?"
Lu Zhou decisively chose 'no'.
'100 years is a bit of a scam. It's a pity I didn't get the Upgrade Card earlier. Otherwise, I could've used it in the ancient formation.'
