I think Yu Wenyue killed Linxi to show Yu Wenhuai. Although Yu Wenhuai was not present, there must be an eyeliner watching in the dark (in fact, the golden candle is the eyeliner). As can be seen from the following plot, he is not dead. Yu arranged a scene for Yu Wenhuai and Yu Wenxi to make them think that they were dead. As Yu's son, Yu is a slave after all, and at this time, he is already highly toxic. Even if I don't kill him, he will die. So Yu was very angry and pretended to punish him for killing his grandfather, killing him and doing all the tricks.
