Yu Xian saw Yu Yiyi coming to her with an inconspicuous little box, "What's wrong, Yiyi?"

"Aunt Yu Xian, this is a gift from Sister Ning Ning, and I accepted it..." Yu Yiyi said with a nervous look on her face. She didn't know if it was right for her to accept such an expensive gift, so she could only come to Aunt Yu Xian for help.

"Oh? What gift? Let me see." Yu Xian opened the box she was holding and immediately recognized that it was filled with purifiers, and it was the purifier before improvement. This kind of purifier can only be bought on the black market. Seeing this, even though she had seen a lot of good things, she couldn't help but reveal a hint of surprise on her face.

Why did you give such an expensive gift?

Yu Yiyi looked at Aunt Yu Xian's solemn face, not knowing what she was thinking. She thought she was unhappy, and suddenly became even more panicked. She took the initiative to admit her mistake and said, "Aunt Yu Xian, I was wrong. I, I will return the things now." However, she felt that it was a bit unfair to Sister Ningning to return the gift like this. Sister Ningning might think that she didn't like her gift and would not be nice to her in the future.

The more Yu Yiyi thought about it, the more frustrated she became. Although she said she would return the gift, she looked so anxious that she was about to cry.

Yu Xian was just thinking about the reason, but when she heard her crying, she came to her senses and comforted her, "It's okay, since it's a gift for you, just accept it. However, since your sister Ningning gave you a gift, we must remember to return the gift, okay?"

These days, debts of favor are the hardest to repay. Purification agents are one of the materials that the cultivation center urgently needs. Even if they can exchange mutant plants with other bases, they can't get them for a while. These purification agents really solve their urgent needs.

Yu Yiyi heard that Aunt Yu Xian did not blame her. She wiped the tears from her eyes and the uneasiness in her heart slowly disappeared. Thinking of picking out a return gift, she said excitedly, "Then I'm going to pick out something better for Sister Ningning!"

Yu Xian looked at Yi Yi who suddenly became happy, and sighed that she was just a child, so easily satisfied. She smiled with relief: "Well, go ahead."

After she finished speaking, Yu Yi excitedly left the room and went to pick out a gift.

Yu Xian looked at her leaving figure and shook her head helplessly. She had never married and had children, and her sister only had Yiyi as her daughter, so she treated Yiyi as her own daughter. She had no other wishes, just hoping that Yiyi could grow up safely.

In fact, to be honest, Yu Xian was very happy that Yiyi had a good friend. Moreover, those two people were quite capable, not ordinary people, and would not approach a child with ulterior motives, so she did not have to worry about Yiyi being hurt in the future.

In the afternoon, Yu Xian called Ruan Ning over alone.

She did not beat around the bush and came straight to the point: "Ms. Ruan, we appreciate your kindness. If you need any help in the future, as long as I, Yu Xian, can do it, I will never refuse." She understood that the purifiers were called gifts, but in fact they were specially given to help the training center overcome difficulties. She accepted the favor.

Ruan Ning smiled and said, "Yiyi is my friend. This is just a small token of my appreciation. You don't have to take it to heart." Her original intention was not to thank them. It was mainly because she liked the training center and wanted to help them on her own initiative. Moreover, today at the training center, the morale of the Cui family was greatly dampened, which helped her vent her anger and made her feel very happy.

Her neither humble nor arrogant attitude made Yu Xian have a better impression of her, so after hesitating for a moment, she finally told him the plan she had made in her mind this morning, "Miss Ruan, I have another unwelcome request. I would like to entrust our home to you for a month."

The theft at the breeding center last time made Yu Xian feel more threatened. Last time, they only stole new varieties. What if they were to attack the people at the breeding center this time? Yu Xian didn't dare to gamble with human nature, especially when the other party was a group of people who would find ways to steal the fruits of others' labor and seek benefits for themselves. These people have dirty hearts and can do anything. As long as there is enough benefit, they might not even blink an eye, even if it means murder and arson.

Yu Xian is not afraid of these people. She will fight with them to the end and will not let their efforts go to waste. If they get away with it, she will live and die with the training center. But Yiyi is different. She is still so young and she doesn't want her to stay in the training center and be scared. The only person Yu Xian is worried about in this world is her. She thought that Yiyi had always wanted to go to the Hope Base, so she thought of handing Yiyi over to the girl in front of her. Before the dust settles, she wants to send Yiyi to a safe place first. The person in front of her is the best candidate, and besides her, she can't find anyone else she can trust and who will treat Yiyi well.

Pay Yu Yiyi to her for one month? What does this sentence mean? ?

Ruan Ning was a little puzzled. She knew how much Yu Xian cared about her niece Yu Yiyi. When they first met, Yu Xian would not let her leave the training center alone in order to prevent people with ulterior motives from hurting her. She was so cautious even in Chaoyang Base. How could she let her follow her to Hope Base for so long?

Yu Xian told Ruan Ning about the recent situation at the training center and her worries. After listening, Ruan Ning roughly understood why she would rather let Yu Yiyi go to another base with herself than let her continue to stay in Chaoyang Base.

The man is innocent, but he is guilty of possessing a treasure. Even though the breeding center has never done anything bad, and has been trying to breed new varieties to benefit all Chinese people, this kind of thing is inevitable because every time they breed new varieties, they attract the attention and covetousness of others. The only way is to become stronger first, so that even if they see it, they dare not covet it anymore, and can only be jealous secretly.

Ruan Ning agreed to Yu Xian's request without much thought, "Don't worry about that. I take care of Yiyi as if she were my own sister. Besides, this is not a request, so you don't have to be so polite." Ruan Ning knew that Yu Yiyi wanted to go to Hope Base to play. It was just a one-month care, which was not a big deal. Yiyi was such a cute little girl, and she liked her very much. How could she refuse such a small thing?

"Thank you, thank you so much." Yu Xian said sincerely. She was really grateful to her from the bottom of her heart. She even thought that if the person in front of her didn't agree, she might have to leave Yiyi in the training center.

Half of Yu Xian's face was burned, and she looked particularly scary. When she pulled her lips to smile, she looked even more eerie. But Ruan Ning didn't feel scared, because she knew she was an honest person. If she liked someone, she liked him, and if she disliked someone, she disliked him.

Ruan Ning likes to hang out with people like this because it makes him feel comfortable being with them and he doesn't have to worry about being plotted against.

Yu Xian stood up and took out a palm-sized mahogany box from the safe hidden in the wall beside her and placed it on the table. "I know you really treat Yiyi as a friend, but you must accept this."

"Well... okay." Ruan Ning knew that if she didn't accept it now, this person would not feel at ease. It would be the same for her. If she wanted to entrust a person to another person, she would never be able to be reassured by just a promise or words of affection.

Ruan Ning knew that the things in the box given by Yu Xian must be unusual. However, when Ruan Ning returned and opened the box, he found that it contained two crystal cores with brilliant light.

People with Ruan Ning's physique do not need to use crystal cores to upgrade, but the two crystal cores in front of her still made her beautiful eyes light up.

——This... is a fourth-order spiritual crystal core and a fourth-order lightning crystal core? !

Because psychics are generally weaker than zombies of the same level. Therefore, a level 4 crystal core usually requires the cooperation of several or even more people. After all, not everyone has advanced to level 5 like Gu Yicheng. To kill a level 4 zombie, they need at least several high-level psychics to work together.

Moreover, after killing the zombies and taking out the crystal cores, they usually use them themselves and will not sell them easily. This shows how popular the fourth-level crystal cores are. And this time, Yu Xian took out two fourth-level crystal cores at once and gave them to her, which was quite generous.

If she had only taken out two fourth-order crystal cores, she might not have been so surprised. After all, she already had several fourth-order crystal cores in her space. The main reason was that these two were exactly what she needed now.

Gu Yicheng's birthday will be coming soon. This is the first birthday they celebrate with each other since they got together. Ruan Ning has been thinking about what to give him as a birthday gift. In the end times, she wants to give him something practical, such as a crystal core. So as early as a month ago, she has been paying attention to whether there is anyone willing to exchange or sell the two types of crystal cores, spirit and thunder. But spirit crystal cores and thunder crystal cores are rare. Even if Ruan Ning is willing to make a loss, she can't find anyone who wants to sell them.

I didn't expect that the things I had tried so hard to get before could be obtained so easily today.

The value of these two crystal cores is no less than the purifier she gave him before.

Ruan Ning and his team did not stay in the Chaoyang base for too long this time. They set off on the second day of the exhibition.

It was a little different from when they came here. When they went back, there was one more person in their car.

"Sister Ningning, can I really stay with you for a whole month this time?!" Yu Yiyi asked excitedly. She thought that she was satisfied with her aunt's promise to let her go for a few days, but she didn't expect that she could stay with her sister for such a long time, a whole month! ! Yu Yiyi felt that everything was like a dream. But if this was really a dream, she hoped not to wake up for the time being, and let her have a good time first.

Ruan Ning helped her fasten her seat belt and said with a smile, "Of course, when has your Aunt Yu Xian ever lied to you? Look, didn't she even prepare your luggage for you this time?"

It took two suitcases to pack Yu Yiyi's things. It can be seen that Yu Xian really loves Yu Yiyi and has thought of a way out for her in advance, fearing that something might happen to her.

In addition to this, Ruan Ning no longer had to spend money to buy the mutant plants and seeds she wanted to buy before. Because when she left, Ruan Ning found that Yu Yiyi also brought a lot of mutant plants and seeds into the car, and said seriously that it was a return gift for her. She also said that she liked the gift she gave her before.

Ruan Ning was a little moved and wanted to laugh, but she finally held it back. She had never met such an honest child.

Since Yu Yiyi settled down with Aunt Yu Xian at Chaoyang Base, she has never left the base gate. This is her first time out of Chaoyang Base. Although she is very curious about the scenery outside the window, she is very well behaved and does not make any noise, which makes Ruan Ning feel very relieved. She also eats whatever Ruan Ning gives her for lunch. She is not picky about food. She is easier to take care of than a picky adult like her.

It was also Ruan Ning's first time taking care of a child, and she found that this feeling was actually not bad.

She thought that if she had a child in the future, she would also want a beautiful and obedient daughter like Yu Yiyi, rather than a naughty son.

However...

Ruan Ning glanced at the person driving the car in the driver's seat. If this person was there, even the most naughty child would not be able to act naughty in front of him.

Ruan Ning couldn't help laughing when he thought about the way Gu Yicheng, a big boss, disciplined his children in a strict manner. Such a scene was really too interesting just to think about.

Gu Yicheng, who was in front, heard her laughter and asked her what she was laughing at and why she was so happy.

Ruan Ning then realized that she was so absorbed in her thoughts that she laughed out loud without noticing. She quickly suppressed the smile on her face, covered her mouth and coughed lightly, then mumbled "It's okay" and tried to get away with it with an excuse.

How could she have the nerve to say what she was thinking about just now? Should she just tell him that she was thinking about how he would discipline their two children in the future? If she really said this, it would be too embarrassing, right? ! ! !

After all, they were still just boyfriend and girlfriend, and the man in front of her hadn't even asked her for marriage.

This is all she is thinking about now. Isn't it a bit too far-sighted?

Half a month later.

The news of the appearance of giant mutant plants in City C and the development of a new variety of plants that could resist zombies by the Chaoyang Base Breeding Center spread to bases of all sizes throughout China in May.

Ruan Ning guessed that the giant mutant plant that appeared in City C was most likely Xiaohua. In the right place, its growth rate was indeed faster. In just half a month, it was so strong that it attracted the attention of surrounding bases.

When Ruan Ning was in the base, she couldn't help but worry about whether Xiaohua would get into trouble. After hearing the news that people from other bases went to City C and returned empty-handed, she was relieved. No matter how Xiaohua grew up or how strong she was, in Ruan Ning's heart, it would always be that small flower bud that was not even as big as her palm.

In addition, the training center spent a lot of money to hire a reliable and powerful mercenary team from another base to guard the training center to prevent the situation like the last time from happening again. Another Cui family appeared.

Fortunately, the arrangement this time should have worked well. Ruan Ning had not heard about what was happening at the training center, and Yu Xian's occasional letters had not mentioned anything bad happening.

During this time, Yu Yiyi had a lot of fun at the Hope Base. Ruan Ning had nothing else to do except go to the army to treat the wounded from time to time. So he often took her to visit the Hope Base. Children like new things, and there are many people in the Dawn Team, so they have a lot of fun every day. Ruan Ning was worried that Yu Yiyi could stay here for one or two days, but if she stayed for too long, she might find it boring. Now it seems that she has adapted well here.

Sometimes when Gu Yicheng has time, he will personally take them to the Hope Base for a walk. In addition, Ruan Ning also found that Yu Yiyi seemed to be a little afraid of Gu Yicheng. Every time the three of them went out together, she liked to hold her hand and stand on her other side, obviously avoiding him. Ruan Ning also found an opportunity to ask Yu Yiyi why she was hiding, and she said that she felt that this big brother always looked at her with a strange look in his eyes. She said that the book said that this behavior should be jealousy between couples.

Ruan Ning was also amused by Yu Yiyi's explanation. Gu Yicheng was the same. He was already so old, why was he always jealous of a little girl who had just entered elementary school? But thinking about it carefully, why did she think that he was so jealous but didn't say a word, and even had a little cuteness in his behavior! ?

Is this what is called beauty in the eyes of the beholder?

Compared with Gu Yicheng, Yu Yiyi's impression of Lin Yang is much better. He called him brother very diligently after just a few hours of being together. Lin Yang is also very good at taking care of children, mainly because he is good at playing games, so when he and Yu Yiyi play together, they get along very well. It may be the revolutionary friendship cultivated by playing games, especially Ruan Ning, Yu Yiyi, and Lin Yang, the three of them spend a lot of time together these days, often playing games until midnight.

Finally, Lin Yang was dragged out to complete the mission, and the decadent days of the three people playing games finally came to an end.

…

Night.

Gu Yicheng looked coldly at Ruan Ning, who had finally found some free time and did not go play games with others. Anyone could see that he was very unhappy at this moment, and even his tone of voice became colder: "Ning Ning, don't you think you have obviously ignored me recently?"

Gu Yicheng found that he had obviously underestimated the popularity of his little girl. Her popularity was not limited to men and women, even non-humans could occasionally act as a light bulb between the two of them to make their presence felt.

He had just sent away a mutant plant, and now there was a half-grown little girl. This light bulb was even more outrageous, with a higher wattage than the mutant plant called Xiaohua. Especially in the last few days, Ningning stayed with her all day long, much more than with her boyfriend. Even at night, he slept in the same bed with her.

All this made the possessive Gu Yicheng feel dissatisfied, and he always felt that he was ignored by his loved one.

Ruan Ning heard his question, a trace of guilt flashed in her eyes, she slowly moved closer, took his hand and shook it intimately, blinked her beautiful eyes, and her long eyelashes swept across, casting a shadow on her slightly pale eyelids. Her voice was soft and sticky, which made people's hearts soften, "Brother, I didn't mean it, please forgive me this time..."

Gu Yicheng pursed his lips tightly and remained silent, with a slight sound coming from his nose.

Seeing that he was still indifferent, Ruan Ning had no choice but to use her trump card. She took the initiative to put her arms around his neck and kissed him.

A minute later, she panted slightly and asked in a soft voice, "Please don't be angry about this, okay?"

Gu Yicheng suppressed the slight smile on his face and tried to maintain the tone of "Am I such an easy person to get rid of?" He said in a hoarse voice: "I'm not angry."

Obviously, she was angry... Ruan Ning stuck out her tongue behind the man's back. It seemed that she had played too much these days and really made him angry. It was all Lin Yang's fault. He gave her some advice, saying that she should ignore him for a few days and then give him a birthday surprise. He said that this would have a significant effect and he would definitely feel surprised.

Forget it. It's already come to this point. There's no point in saying anything more. Let's just get down to business. I'll continue explaining this to him after things are over.

Ruan Ning secretly glanced at the time on his watch. It was exactly twelve o'clock.

Not too much, not too little, just the right amount of time.

Sure enough, just after the second hand passed twelve o'clock, the power to the villa was shut down by people downstairs.

The surroundings immediately fell into darkness.

Ruan Ning took out from the space the birthday cake that she had consulted many people and prepared for a long time before she successfully made it herself. The orange candle light reflected in her bright and clear eyes, like stars, which was very beautiful.

"Brother, happy birthday~"
