The Villain Kills the Protagonist and His Family at the Beginning

It was a systematic start, but it was too late and the whole family was killed. Is there anything we can do? There is no other way. I cannot bear the pain alone, so I can only ask the protagonist's family to die. The protagonist's confidante will be killed as soon as possible. War Temple, leader of the martial arts alliance? Haha, everything is fake. If you encounter the clone army of the system, you should not be able to defeat it. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
