Chapter 839: The Foreigner Makes His Move!

"Grandpa Yun, haven't you heard that medicine and poison are closely related? I am a doctor, so I must understand poison. If I don't, some illnesses are hard to cure. Poison doesn't always hurt people; it can save them too. That’s why we have the saying 'fight poison with poison.'" Zhu Yanyi did not avoid the question. She needed to explain things clearly to the old master.

"Can these poisons be promoted?" Grandpa Yun’s idea of promotion meant spreading them to the army.

Zhu Yanyi shook her head slightly. It wasn’t that she couldn’t, but she didn’t want to. "Grandpa Yun, please don’t put me in a difficult position. I can study and control poison because I have the ability, and I have no intention of using it to harm others. But others might not be the same."

Human nature is the hardest thing to figure out. Some people are truly terrifying. The poisons in Zhu Yanyi’s hands were not simple ones. If used well, they could bring great benefits to China. But if someone had bad intentions, these poisons would become tools for harm. Zhu Yanyi did not want this to happen. She did not want her poisons to be used by strangers.

"Can’t you share them?" Grandpa Yun looked regretful. After hearing Zhang Hua and Old Yang, he knew the poisons Zhu Yanyi possessed were extremely potent.

Zhu Yanyi sighed and looked at Grandpa Yun. "Grandpa Yun, poison should only be used to harm people as a last resort. Hurting others hurts yourself. If you really need this poison, you must investigate everything about the person. You must decide exactly where and how much to use. Then I will give you a fixed amount. If you use it, someone must prove how much was used. I will take back any unused portion. If you can accept this, you can ask me for poison later."

Grandpa Yun was silent for a moment. "I will think about it." He naturally knew that Zhu Yanyi’s strict control was for everyone’s good. Poison truly should not fall into the wrong hands.

He needed the poison, but only under specific conditions. Grandpa Yun needed to think carefully.

Starting the next day, the families of the seven children arrived one by one. Seeing their children safe, though thin, every parent felt heartache.

Tiantian’s grandmother held Tiantian tightly, crying non-stop. "Tiantian, Grandma missed you so much."

"It’s all Mom’s fault for not taking good care of you," Tiantian’s mother cried beside her, blaming herself for being pushed.

Tiantian’s father wiped tears nearby. During the days their child was missing, their family had nearly gone mad.

Tiantian also cried. After a long while, he said, "Dad, Mom, Grandma, I missed you. I want to eat snake soup."

"Okay, Grandma will make snake soup for you when we get home." Tiantian’s grandmother knew her grandson loved snake soup best, so she agreed immediately.

Dandan’s grandfather held Dandan and refused to let go. His grandson was lost and found again.

Every family was like this. For them, having their children back was a rare and precious thing.

When everything was settled and they processed the paperwork to go home, the children wanted to see Zhu Yanyi one last time.

Hearing that the children insisted on seeing her before leaving, Zhu Yanyi came over. Tiantian saw her and shouted, "Sister is here."

Dandan also came over, holding Zhu Yanyi’s hand. "Sister."
