He just got the opportunity for this special reward.
The [Sixth-Level City Lord's Mansion Upgrade Certificate] just came along.
Of course, this is just Zong Shen's speculation.
It could also be due to his good luck.
The reward mechanism is not that important because obtaining such a special reward is not easy.

The remaining two reward items are quite novel.
He took out the blueprint, focused his eyes on it, and started to examine it.
