I would like to the name of the manhua. The description of the manhua is as follows:

The main character (MC) is a teenager whose father is a lord and the MC has a kind stepmother and a tsundere stepsister. The MC always sleeps. Then a man comes to a village, rents a house, and starts practicing sword fighting for the rest of the file  ("Pre-sequel of the story"). 

This same man appears in the MC's dreams and starts practicing sword fighting in his dreams, prompting the MC to wake up and start practicing sword fighting himself. Then an old man sees him practicing and recommends him to a sword fighting school, in which he befriends the top candidate, who is a girl, and his rivals are a boy and another girl.

In the final exam they conduct, everyone is asked to show their sword fighting style and the MC simply does a vertical slash and breaks a building. Meanwhile the MC's stepsister becomes a powerful mage, and then a cat comes along, saying he is an extraordinary species, and teaches the MC about magic, during which the MC goes into a coma for a few months.

That's all that I remember. If anyone knows the name of the manhua kindly do tell.

Thanks in advance.
