I Picked Up Skill Fragments In The Monster World

Introduction 1:
Zhang Chen travels to a mysterious world where he can randomly pick up talent skill fragments from monsters - and add points for unlimited upgrades.
And all of this started when the Yellow River overflowed and someone wanted to turn a dragon into a dragon. The county annals record that in the 16th year of the Great Wednesday, it coincided with the Grain Rain season:
A man told his family before his death that they would throw him into the river after his death, and remember not to wear any clothes. The family couldn't bear it and put flowery pants on the body. Ten years later, there was a major flood, and a white dragon wearing flowery pants jumped out of the river and saved the whole village...
"Hey, that dragon, your water control skills are gone!"
