A moment later, Zhou Shu came out of Xiaoyu'er's grotto-heaven with a thoughtful expression.
Xiaoyu'er's grotto-heaven was indeed several times larger than before, and there was already a preliminary ecosystem inside. As long as living people didn't stay inside for too long, there shouldn't be too much of a problem.
