I understand the meaning of a feast for the eyes

Lu Zheng leaned forward on purpose, almost causing Gu Xin to fall.

"Brother Yuanyuan will teach you today. Never let down your guard against the enemy at any time!" Lu Zheng said with a smile.

"Brother Yuan Yuan isn't an enemy!" Gu Xin pouted.

Lu Zheng squatted down and let Gu Xin down. He then pinched her face, " "When we fight, you have to think of me as an enemy."

Gu Xin nodded,'Oh, alright! Brother Yuanyuan, hurry up and wash up. Look, your head is covered in sweat. You still need to wash your hair, right? I'm hungry, so I'm going to buy breakfast. I was going to ask you to eat with me, but you can wash your hair, and I'll go to the corner to buy it. "

Lu Zheng could feel Gu Xin's dislike. Alright, he went to wash his hair.

When he was removing his hair, he realized that there was an additional hairpin on his bun. He was stunned for a moment. He took it down and saw a Jade hairpin. It was a very simple Jade hairpin with the word " Yuan " carved on it.
