The wife of the rebirth era has a system

Lin Nan heard it when he was calming down in the room, and knew that Tong Momo might have a fever, so he rushed out to meet Cheng Li who came in, and heard Cheng Li say: "Nan Nan, come and take a look, Momo seems to have a fever."

Lin Nan immediately reached out and felt it: "It's hot, yes, it's a fever."

Cheng Li asked: "Then do you need to take antipyretics now?"

Lin Nan instructed Cheng Li: "Don't feed her yet. Put her on the bed and I'll show her. There are many types of fever. It depends on which one it is, so we can prescribe the right medicine."

"it is good."

Cheng Li carefully put Tong Momo on the bed.

Lin Nan sat down and felt Tong Momo's pulse, because he couldn't rely on the system all the time, Lin Nan was studying whenever he had time, and his medical skills were very good now.

But when she touched Tong Mo's door, she still frowned.

Pulse, very wrong.

Seeing that Lin Nan's face was ugly, Cheng Li asked, "What's the matter?"

Lin Nan shook his head and quickly connected to the system hospital.

The results showed [gene mutation! 】

Lin Nan: "..."

What exactly does this mean?
How did the gene mutate?

If Lin Nan can't figure it out, it depends on the treatment method.

I saw that the above is [Need to absorb the crystal nucleus to quell the riot in the body. 】

The problem is that this kind of crystal nucleus is only available to zombies with levels in the last days, and it is not stored in the system hospital.

Seeing Lin Nan's changing expression, Cheng Li couldn't help but ask again: "What's the matter?"

Lin Nan had no choice but to tell Cheng Li about the matter.

After finishing speaking, he opened the system mall and searched for crystal cores. Some of them were found, but they belonged to strange beasts, and one belonged to zombies. Unfortunately, they were out of stock.

Lin Nan didn't even know what mood she was in right now.

Just when Lin Nan had nothing to do, the system finally sent a prompt [Ding Dong!The system upgrade is complete. 】

Lin Nan lost her composure when she heard it: "System, you have finally upgraded."

The system was a little flattered [So excited, can't it be that you have encountered trouble? 】

Lin Nan: "Bingo, the system of those who know me."

system【……】

【what happened? 】

Lin Nan told about Tong Momo's situation.

After finishing speaking, he said again: "Now we must find a way to get the crystal nucleus, otherwise Momo is only afraid of danger."

After the system heard it, 【Mo Mo's parents are both people of the last days. During the last days, many human physiques have undergone mutations. Although Mo Mo's mother is an ordinary person, her father has supernatural powers. It is normal to have genetic mutations. 】

After hearing this, Lin Nan said, "I just thought of this, what should I do now? System, do you know where I can get zombie crystal cores?"

The system said [If you can't even get it in the system mall, you can only go to the end of the world. 】

"What?" Lin Nan exclaimed: "Go to the end of the world, system. Are you sure you are not joking?"

System [Human life is at stake, would I joke about this kind of thing? 】

Then explained to Lin Nan [After the system upgrade, the main system gave the host the opportunity to travel through time and space three times a month. 】

Lin Nan: "This main system won't predict the end of the world, so that's why it's arranged like this?"

System [The main system has its own reasons for such an arrangement. Okay, are you going to the end of the world to find crystal nuclei for the end of the world? 】

Lin Nan looked at Mo Mo who was crying, and said firmly, "Go."

System [Okay, let’s get ready, the end times are very dangerous, so prepare more life-saving things. 】

"it is good."

Cutting off contact with the system, Lin Nan finished talking to Cheng Li about going to the end of the world, opened the system mall, and started buying equipment.

After Cheng Li heard Lin Nan's words, his face became ugly. He didn't want Nan Nan to take risks, but he couldn't watch Mo Mo die.

He asked: "Nan Nan, you can ask the system if you can let me go there. I am skilled and it is easier to get the crystal nucleus."

As soon as he finished speaking, the system said [No, this time-traveling condition can only be used by the host. 】
