We Agreed To Be An Idle Son-in-law, You Land God?

Outrageous, Chen Yi traveled through time and opened his eyes and found himself in the execution hall of the Hou Mansion - just because he was a surrogate son-in-law, but he escaped from the wedding on his wedding day.
So not only was he not welcomed by the Hou Mansion, he was also grounded and punished.
However, Chen Yixing enjoys his leisure time. In his previous life, he worked hard all day long, so in this life it is better to be an idle son-in-law.
Since then, he has relied on daily intelligence to gain opportunities, intensively studied music, chess, calligraphy, painting, medicine, fishing, etc., and lived leisurely in the Hou Mansion.
[Daily information: Xiao Wuge, the direct grandson of Marquis Wu, will gain a lot of opportunities if he fights with the eldest son Zhang Hengda. 】
Chen Yi looked at the content and fell into deep thought.
"There is something wrong with this system."
...
Many years later, Chen Yi, who had perfected his skills in music, chess, calligraphy, painting, medicine, and fishing, faced the invasion from the barbarians, and had no choice but to step into the land of the gods and fight to the amazement of the world.
Xiao Jinghong: "Husband, we agreed to be an idle son-in-law, you land god?"
Chen Yi hugged her and said with a smile: "It's all your brother Xiao Wuge's fault..."
Who would have thought that the grandson and crown prince of Marquis Wu was only five years old?
Daily information? No, eat melon today!
PS: Eat melons, relax, be honest, pretend to be pigs and eat tigers
PPS: Also known as "The Leisurely Life of the Marquis' Son-in-law", "Wherever there are melons, there is me", "Husband, do you dare to go fishing today?" 》
