Ask for an urban power novel long ago, in which the hero has the ability to become other people, and a chapter is written by one woman and another.

He is the king of the Tang family. The protagonist's parents are engaged in research and have been abroad. When the protagonist was eighteen, he received a reagent, which was left to him by his parents after he was killed. Later, someone traced it to his house and accidentally broke the reagent. Since then, he has the ability to absorb the power of others. This book is very nice, I recommend reading it!
