Can't Afford to Offend My Scheming Disciple

*On the day he was 23 years old, he was lying on his sickbed, quietly leaving this world. He did not expect that he would be transported to a novel about cultivation, where the heavens gave him a healthy body.
 Looking at his little Nanchen, he thought to himself, "This time, I must treat him well."
He (Nanchen) was supposed to be a son of heaven, a Foundation Establishment cultivator at the age of ten. 
He had a master who doted on him, but he didn't expect his master to be a hypocrite who killed his parents and raised him up like a cauldron. 
He had obtained the Devil's Note and became the Demon Lord, yet he still died under his sword. When he woke up again and was six years old, he would live a new life again.
