I picked up skill fragments in the demon world

Zhang Chen traveled to a mysterious world, where he could randomly pick up talent skill fragments from demons - and add points to upgrade infinitely.

And all this started when the Yellow River flooded and someone wanted to turn into a dragon. According to the county annals, in the 36th year of the Great Zhou Dynasty, it coincided with the Grain Rain season:

a man told his family before his death that he would be thrown into the river after his death, and remember not to wear any clothes. The family couldn't bear it, so they put a pair of flowered shorts on the corpse. Ten years later, a major flood broke out, and a white dragon wearing flowered shorts jumped out of the river and saved the whole village...

"Hey, that dragon, your water control technique has fallen off!"
