The more that she feels sick, the more that she thinks about it. 

Memories of these years keep coming back to her mind. If it weren’t for Jiang Ning’s teaching, Doudou might still be a people-pleaser, either trying to please others without a bottom line or keeping everything in her heart and not telling her brother. 

It was Jiang Ning who corrected her shortcomings in time, helped her build confidence, and brought her closer to her brother. 

Doudou threw herself into Jiang Ning’s arms, “Sister-in-law, I’m really glad that you’re not the one who got hurt.” 

Jiang Ning choked and hugged her tightly. 

The condition kept recurring, and the two were worried and took turns to stay by the bed. 

There was one time when they almost had to use a heart stimulant. 

After burning with fever for five days, it finally came down. 

Not only did Doudou lose weight, but Huo Yishen and Jiang Ning also lost several pounds, and Coke also had a poor appetite. 

All the tests that could be conducted were performed, and all indicators were low. No significant organ damage was also evident. 

They had temporarily won this battle. 

But it was extremely dangerous; without the oxygen machine and the many medications, they would have had to leave it to fate. 

Huo Yishen was still uneasy, so he pulled Jiang Ning aside, “Is Doudou really okay now?” 

Jiang Ning couldn’t guarantee it, “When Yang Weimin had mutated squid at Aoyuan, he was fine after having his stomach pumped. So not all ancient viruses are fatal. It should depend on the specific type of virus, the amount of virus, and the host’s physical condition.” 

The sea tide bugs are formidable. When they encounter the monstrous creatures, they swallow it skin and bones. There must be a lot of viruses in their bodies. 

Without detection methods, Jiang Ning is not sure whether the virus has been killed or coexists with the cells in Doudou’s body. 

She didn’t want him to worry, so she gently said, “She should be fine now. Let’s take care of her body during this period and let her exercise more to improve her resistance. The Ghoul drank so much nuclear wastewater and ate mutated marine creatures for so many years and can still survive. Doudou was just bitten so let’s continue to observe.” 

Huo Yishen was relieved and hugged her tenderly, “Anning, you have worked hard during this time.” 

“As long as Doudou is okay.” Otherwise, she didn’t dare think about what might happen in the future. 

Jiang Ning told Doudou to have a good rest and to tell her if she felt any discomfort. 

Doudou was very weak after a serious illness, but the joy of successfully surviving the disaster made her smile. 

When she was in a bad mood, she saw many survivors die in front of her, and sometimes she thought that death might not be a bad thing. 

But when she was on the verge of death, she really didn’t want to die and felt a strong desire to continue living. 

She wanted to eat delicious food, play with Coke, and have future nephews and nieces. Everything made her so reluctant to leave.

Jiang Ning was very concerned about Doudou. Not only did she have rich and delicious meals three times a day, but she made sure that she take herbal medicine regularly to regulate her body. 

Considering her weak body, the submarine stayed on the seabed without floating up, for fear that Doudou would catch a cold. 

After waking up from a nap, Jiang Ning sat in front of the observation window, drinking juice and reading magazines to kill the boring and long time. 

Suddenly, Doudou came over, her voice was full of panic. “Sister-in-law, I don’t feel well.” 

Jiang Ning looked up, only to see her face pale, with beads of sweat pouring from her forehead. She couldn’t help but jump in shock, “What’s wrong with you?” 

“I, I…” Doudou was too embarrassed to speak; her face turned red. “I’m bleeding.” 

“Where are you bleeding?” 

Jiang Ning checked her face and hands, and there were no strange lumps on them. 

“I, I’m bleeding here.” Doudou held her stomach tightly, tears falling. “Sister-in-law, I’m going to die.” 

Where? Jiang Ning was stunned and saw that she had been holding her stomach tightly, and it took her a while to realize it. 

Blame her. She taught her everything except physiological knowledge. 

Doudou is almost 15, the age to have her first period. 

Jiang Ning hurriedly comforted her, “You’re not sick, you’re growing up.” 

Hearing his sister crying, Huo Yishen came out of the room, “Doudou, what’s wrong with you?” 

Although she didn’t know much about physiological knowledge, she still knew the difference between men and women. Doudou felt particularly ashamed thinking about bleeding in that place and didn’t know how to tell her brother. She hesitated and didn’t say anything, and her tears fell even harder. 

Her pants were wet, and she hid behind Jiang Ning awkwardly, not daring to let her brother see. 

Jiang Ning yelled at him, “It has nothing to do with you, don’t ask around, go back quickly.” 

Huo Yishen was confused by the yelling, and he didn’t know what to say, so he had to touch his head and go back to the room. 

Jiang Ning pulled Doudou back to the room and gave her some knowledge about female physiology, “Doudou, when girls grow up, they will have menstruation every month. From today on, you are an adult.” 

Doudou was confused and took a while to digest it. 

It turned out that she had grown up and was no longer a child. 

It’s great that she can be independent now, and her brother and sister-in-law don’t have to take care of her everywhere. 

Although humans might become extinct, who knows what will happen in the future? Jiang Ning also taught her about sex. 

Such a beautiful girl, what if she is kidnapped by a bad man one day and got pregnant? 

She doesn’t even dare to think about it! 

Doudou was even more confused after hearing this, and she felt vaguely embarrassed, and her face turned red. 

She lowered her head and pinched the corner of her clothes and said fearfully: “Sister-in-law, I won’t let men touch me, not even for a moment.” 

As she said that, her soft and sweet face suddenly became fierce. “If they dare to touch a hair on my head, I’ll kill them!” 

Jiang Ning was frightened by her. “Oh, there is no need to be so agitated. If you meet someone and they are not sincere enough, they are either a traitor or a thief. Just stay away from them. Even if you meet someone you like one day, you must think carefully before making a decision, and don’t give yourself up easily.” 

“Remember, you must know how to protect yourself. If conditions do not allow, don’t get pregnant.” 

Zheng Weili and Xiao Min are living examples, but Zheng Weili is lucky enough to survive. 

Doudou nodded. 

Perhaps after experiencing this, it was as if they had a common secret, and the relationship between the aunt and the sister-in-law became closer. 

The ignorant Doudou was curious and couldn’t control her mouth for a while. “Sister-in-law, why did you let your brother touch you?” 

Her brother and sister-in-law would make strange noises at night, as if they were fighting, but not necessarily. In short, it made people feel flustered and shy, so she could only hold it in her heart and didn’t dare to ask. 

She didn’t dare to ask anything! 

She pretended that she was sleeping soundly. 

But she secretly observing them the next day, her brother and sister-in-law seemed to be closer, as if nothing had happened last night. 

It’s really strange. 

Jiang Ning took a breath of cold air. “…” 

Facing Doudou’s clear eyes, Jiang Ning couldn’t avoid it and could only simply say, “Because your brother is very good, a person worth entrusting to stay with.” 

Doudou felt the same way, sister-in-law is good, brother is also good. 

Jiang Ning touched her head. “Doudou, if you meet someone you like in the future, he must be better than your brother in every aspect before you can trust him, understand?” 

“Yes.” 

But Doudou thought there may be no better man than her brother in the world. 

At least in all these years, she has never seen anyone better and more powerful than her brother. 

Jiang Ning went back to her room and took out several packages of sanitary napkins. 

Huo Yishen suddenly realized, “Doudou has grown up?”
