After finishing this, Shen Qingqing returned to check on the remaining mice. After observation, although these mice were in a depressed state, they were no longer in danger of death, and after a period of eating and resting, they recovered a lot.

Shen Qingqing finally breathed a sigh of relief. If all these little white mice had died, she would have felt so guilty.

Shen Qingqing confirmed the efficacy of the two drugs, and then decided to make more pills so that she could give them to Zhou Yuanzheng. If anything happened during the mission, they could help.

Shen Qingqing made up her mind, so she continued to process the purchased medicinal materials, trying to make more before Zhou Yuanzheng left.

The night before Zhou Yuanzheng was leaving, he was packing his things. Shen Qingqing called him into the bedroom, then took out a small box from the cabinet and handed it to him carefully.

Shen Qingqing's voice was very soft, just loud enough for two people to hear.

"This is for you. Remember to take it with you."

Zhou Yuanzheng was a little curious, "You are so mysterious, what are you doing? What is this?"

Shen Qingqing motioned for him to open it.

Zhou Yuanzheng opened the small box, which was divided into two layers. The top layer contained small dark brown pills, and the second layer contained light yellow pills.

"What is this?" Zhou Yuan was puzzled.

Shen Qingqing smiled mysteriously, "This is the secret martial art I gave you."

"Secret weapon?"

"Yes, you must remember this. The first layer of dark brown is poison. It is very toxic. Be sure not to ingest it by mistake. If you have touched it with your hands, remember to wash them before doing anything else. The second layer of white is the antidote. Do you remember?"

"Let me tell you, don't underestimate this pill because it's very toxic. It won't kill you, but it will stimulate your nerves and sense of pain. Once you're infected, it will hurt so much that you lose your mind. But don't worry, the antidote is already prepared."

Upon hearing this, Zhou Yuanzheng immediately felt that the small box in his hand was a little hot and almost threw it out.

"No, I don't dare to take this."

Shen Qingqing didn't understand his behavior, and hurriedly advised him, "Why don't you take it? What if you need it? No, you have to take it with you."

"I can't bring it. It's against humanism. Even if I really need it, I can't use it!" Zhou Yuanzheng replied helplessly.

Shen Qingqing was firm, "No, you have to take it with you! I tell you, when you really need it, don't worry about whether it's human or not. Life is the most important thing, don't you understand?"

"Come on, repeat it to me. The dark brown is the poison, and the light yellow is the antidote. Remember, don't get them mixed up."

Zhou Yuanzheng thought about it for a long time and finally decided to accept it.

Zhou Yuanzheng counted them and confirmed that there were only four poison pills and four antidote pills respectively, then he put the box close to his body with confidence.

Shen Qingqing watched him put the things away before she felt relieved. Finally, she couldn't help but remind him again, "When it really comes in handy, remember that your life is the most important. And don't worry about humanism, understand?"

Zhou Yuanzheng looked at her with amusement, "Why, are you worried that something might happen to me?"

"Puh, puh, puh!" Shen Qingqing was so angry when she heard this that she wanted to hit him. "Why are you talking so badly? You will definitely come back safely, don't you know?"

"I know, I know. Look at you, you're so scared." As he said that, Zhou Yuanzheng pulled her into his arms and stroked her soft hair soothingly.

"Wife, I promise you, I will come back safe and sound, don't worry too much, okay?"

Shen Qingqing simply found a comfortable position in his arms, put her arms around his waist, and gently rested her head on his chest.

The man's heartbeat was like a drum and thunder, but it made Shen Qingqing feel particularly relieved. She couldn't help but sniff. She was really scared, afraid that even if she helped Zhou Yuanzheng escape the disaster last time, the fate of death would still find him.
