"Miss Zi Yan, I’m not that much older than you are. Let’s talk as equals. You may call me senior brother Hua."

Zi Hua was momentarily taken aback, but then opened her mouth as if to speak.

"Miss Zi Yan!" Su Ming’s second senior brother’s face grew more stern. "I said that I would bear the responsibility for his wrongs. How about this, I’ll follow you to the seventh summit and punish myself to protect you for three years. I’ll use these three years to compensate for Hu Zi’s mistake."

Once the second senior brother finished speaking, he sighed. If Hu Zi was by his side and saw the gentleness on his face along with the persistence in his words, perhaps… just perhaps, he would be very touched?

"Senior brother Hua… There’s… no need for that."

Zi Yan felt that she could not handle him and took a few steps back.

"Are three years not enough? Alright then, ten years. I’ll punish myself to go to the seventh summit and protect you for ten years."
