章 4273: Soul realm's Ten Kingdoms (1)

Liu Yu stared blankly at little crane grass's back. Little crane grass was pulling Xiao Yu 'er out of the house, and Xiao Yu' er was obediently following by his side. There was nothing unusual about the two of them, just like an ordinary brother and sister who were about to go home.

However, Liu Yu looked as if he had just seen a ghost. He had really tested the knowledge of the little crane grass just now, but the result was really hurtful.

Liu Yu considered himself one of the few meticulous people among the servants of the Liu family. In terms of knowledge, he was not inferior to anyone. He even believed that there were not many servants in the Liu family who could surpass him in knowledge. However, when he tested the little crane grass today, he did not succeed. This was extremely shocking.
