章 677: 12.79 Unknown Star - Modern ABO World: Second Case - Siblings

Crossfield Private High school's old building. 

Abandoned Biology Laboratory. Secret Storage and Laboratory of the mad scientist, Datura. 

Hei Yuhua and Hei Yumei finally meet each other. It was an abrupt meeting and both sides didn't expect this to happen. They could only stare at each other's faces which look similar to each other. The only clear difference is their gender.

They both asked at the same time.

Hei Yuhua asked, "Who are you?"

"Are you my elder brother?" asked Hei Yumei.

The question of the young lady froze Hei Yuhua in shock. He had the feeling that the woman in front of him was indeed connected to him by blood. Her appearance alone says everything. It wasn't just a simple similarity but instead, a certain inexpressible feeling was filling his heart at this moment. When he heard her call 'Elder Brother' Hei Yuhua didn't know how to react at all.
