Mistaking the real dragon for a good-for-nothing

In his past life, after Li Zhou was reunited with his biological parents, he went out of his way to please the whole family. He even unreservedly contributed his scientific research achievements to his biological father's company, helping the Wang family's enterprise leap to the pinnacle of Huaguo's pharmaceutical field. However, his sincere efforts only earned him the family's disdain. He endured false accusations in silence and silently bore the exploitation, until that laboratory explosion occurred. On his deathbed, Li Zhou finally saw the Wang family's heartlessness clearly and discovered that the accident was deliberately orchestrated by the adopted son, Wang Yan, to get rid of him! Reborn in this life, Li Zhou decides to fight back forcefully.
