What is the ending of Nannan in the world?

In the world, Nan Nan is the child born of Luo Shibin's invasion of Zheng Juan.

Luo Shibin got drunk, invaded Zheng Juan, and Zheng Juan got pregnant. Zheng Juan wanted to abort the child, but Zheng Juan's mother believed in Buddhism, so she was not allowed to abort the child.

When Zheng Juan gave birth to Nannan and saw her son so cute and likable, she was even more reluctant to part with her children. From these details, we can know why Zheng Juan kept the child because of kindness and sympathy.

Nannan's ending in the world

One day at the end of class, a boy suddenly broke into the classroom and shot at random. When the gun was pointed at a college student, Zhounan Station stood in front of her. The boy pulled the trigger without hesitation, but the bullet got stuck.

The other party immediately turned the spear head and aimed at another stunned girl. Nan Zhou covered himself for the second time, and the pistol got stuck. The boy pointed a gun at the old professor again. Nan Zhou thought the pistol was out of bullets, so he jumped at it. A gunshot sent a bullet into his chest.
