What do you need, I don't know what needs me, but...
I don't like this feeling...
the bustling Jing Town, standing alone in the smoke of troubled times, even the most authoritative place, has to be controlled by the most powerful princes recently, which is why all the princes are eager to go to Luoyang
the idea of holding the emperor to order the princes has been conveyed in another continent more than 1000 years ago
"..."
today's weather is just the right wind. There is always a peaceful place in the noisy center. There is an open space outside the solemn shrine, which is inaccessible to ordinary people. Only a little girl is flying a kite quietly
if you capture the plain expression carefully, you can detect a trace of happiness
I don't know what the bondage is, but temporary relief can have such an expression
"..."

"..."
her little face was slightly red, but she did not forget to stare at the paper kite on the unknown person

once, twice
the tree branches fell continuously on the sleeping person's face, but they didn't react much. The girl's forehead trembled slightly< br/>“……”……
