For Li Zhirui, the grade of the Spirit Stones doesn't significantly impact the space generation, so there's no need to use more precious higher-grade Spirit Stones.
"Please wait a moment, I will bring the Spirit Stones right away," said the Elder as he picked up the Jade Token and deducted the corresponding Contribution Value with a special Magical Treasure.
During this process, he inevitably saw Li Zhirui's Contribution Value—an extended series of numbers that required careful counting, making his heart skip a beat.
As the Miscellaneous Affairs Elder in charge of exchanging various Spiritual Objects for the Li family, and someone knowledgeable about the family's resources besides the secret vaults, he was still shocked.
If Li Zhirui wished, he could exchange all the Spirit Stones in the family's storage, and there would still be plenty to spare!
From this, it's clear how substantial Li Zhirui's contributions to the family have been!
