The landlord was upstairs in the house he rented, and after Cheng Zixuan knocked on the door, he heard a crisp girl coming.

"Who?" soon an eye appeared at the cat's eye position. Cheng Zixuan beckoned to the cat's eye, the door was opened, and a short-haired girl with bright eyes and bright teeth appeared inside and said to Cheng Zixuan with a smile: "Brother Cheng, why are you here today?"

"I'm looking for Sister Liu, is she at home?"

"Today's supermarket sale is huge, Mom, she went out to buy something, and she probably won't come back for a while. Do you want to come in and sit down and wait for your mother to come back? As she spoke, the girl picked up a pair of slippers and put them on the floor, and invited Cheng Zixuan into the house.

Originally, I wanted to say that Cheng Zixuan, who was waiting downstairs, couldn't go down any longer, so he simply took off his sneakers and put on slippers and walked in. The short-haired girl is Sister Liu's daughter, named Liu Xinting, because her father is also surnamed Liu. However, it seems that he and Sister Liu are separating now, and Cheng Zixuan is not clear about the specifics, after all, this is someone else's family matter. Liu Xinting is also in her first year of high school this year, and she and Li Qinghan are not in the same school, so they don't know each other. However, the biggest difference between her and Li Qinghan is that she is very enthusiastic about Cheng Zixuan, that is, Cheng Zixuan thinks that this child is too enthusiastic.

As soon as Cheng Zixuan sat down on the sofa, Liu Xinting walked to the kitchen and said, "Brother Cheng, do you want to drink something?" Tea is still a drink, and there are juice and coke in the drink. ”

"The juice is good, thank you Tingting. ”

Cheng Zixuan thought with emotion, look at how polite people are, they are also female high school students, why are they so polite.

"Hey, hey, hey" The girl opposite laughed while sitting on the other side of the sofa and watching Cheng Zixuan drink juice. I don't know why, Cheng Zixuan suddenly felt that the expression on the face of the girl opposite was very similar to the expression on his face when he fed Kunkun (little earth dog) for dinner.

Maybe it's wrong, I'm not a pet, what's so fun about feeding me.

It wasn't until the girl on the other side smirked for almost five minutes that he finally couldn't help but say, "Tingting, don't you have to do something, just sit here and watch me drink juice?"

"Oh," the girl suddenly realized.

"How about Brother Cheng come to my house to tutor me in math homework, people think math is so difficult(>_<)," the girl said shyly.

Hey, girl, how fat is your tone in the second half of the paragraph, and you suddenly changed into a person.

"Yes, when I was a freshman in high school, I almost got a perfect score in math a few times. Cheng Zixuan said confidently.

"Come to my room, I was doing my homework. The girl pulled up Cheng Zixuan's sleeve and led him to her boudoir.

"I think it's better to be in the living room, now it's only you in the house, it's not good. After all, Cheng Zixuan is an adult, and he subconsciously feels that it seems a little wrong to enter the girl's room when the other party's parents are not at home.

"It's okay, it's just that tutoring homework can be anything, it's a big deal not to close the door," the girl said generously.

"I think it's still ......," Cheng Zixuan didn't finish speaking, and before he finished speaking, he saw Tingting accidentally use her arm to knock down half a glass of juice that she hadn't finished drinking and spill it on the table.

In the end, Cheng Zixuan still had to tutor her in Liu Xinting's room, because the girl thought that even if she wiped the juice table, it would be damp, which would make her textbooks dirty.

Although he was in the girl's room, Cheng Zixuan still asked to open the door, because he always felt that if Sister Liu went home, he and Liu Xinting were still closed in the room, and they might be humanely destroyed by Sister Liu on the spot.

Regarding the request to open the door, although Liu Xinting had some regrets, she reluctantly agreed.

This girl doesn't really want to see me be humanely destroyed, Cheng Zixuan thought.

Curiously looked around the girl's boudoir, the pink hue and a large number of various plush dolls at the head of the bed, and there was a faint fragrance when you sniffed it carefully. Cheng Zixuan could still see the girl's white neck when he looked from behind, and then looked down..... Just as he was looking at the girl in a trance, Liu Xinting seemed to look back at Cheng Zixuan with some sense. All of a sudden, time seemed to stand still.

"Brother Cheng, you, why are you staring at me like this" The girl said shyly.

Just when Cheng Zixuan felt a little embarrassed and overwhelmed, fortunately, Sister Liu's opening broke the embarrassment.

"Hey, Tingting. Whose shoes are they at the door? ”

"Hello Sister Liu, I came to you for something. Cheng Zixuan hurriedly walked out of the room and said.

"Oh, it's Xiao Cheng, I haven't seen you in a while. Why did you come to me today for something?" said Sister Liu.

"I'll help you bring your things back first. Cheng Zixuan said.

"Then I'm sorry for you, Xiao Cheng, I always ask you to help me. Sister Liu said with a smile that she did not refuse Cheng Zixuan's help.

After putting away the things, Cheng Zixuan said to Sister Liu: "Sister Liu, I came to you to tell you about the house deposit, and I am ready to return the house." ”

"What's wrong, Xiao Cheng. Isn't there still two months left to arrive, if you don't have money, the eldest sister can lend you some first, and I can't let you sleep on the streets," Sister Liu was surprised.

"No, no, no," Cheng Zixuan hurriedly waved his hand.

"Well, I got a new job in the suburbs. The new company has dormitories, and it's three or four hours away by car. So I had to move out for convenience. Cheng Zixuan explained.

"That's good, that's good. I'm going to get you the money, you wait. After speaking, Sister Liu walked to the bedroom, and after a while, she took a brand new envelope and handed it to Cheng Zixuan.

"Come on, Xiao Cheng, count and see if the money is right. ”

Cheng Zixuan glanced at the envelope, which was the one he had deposited for Sister Liu.

"No, no, I'm troublesome. Besides, how could I not trust you for this amount of money. Cheng Zixuan said politely.

"Oh, you kid, you'll be deceived in the future if you're so sloppy. Sister Liu said worriedly.

"No, no. Cheng Zixuan smiled and said.

"Then Sister Liu, I'll leave first, and I have to move my things back to the company dormitory. ”

"Xiao Cheng, you always pick this kind of time to come over when you have just eaten, and you can't invite you to a homely meal, it's really too out-of-the-box. Tingting, Brother Xiao Cheng is leaving, come out to send them off. Sister Liu said to Liu Xinting's room.

Liu Xinting, who had been eavesdropping behind the door for a long time, immediately walked out.

"Come on, Brother Cheng. I'll help you get your stuff in the car. It's better than going back and forth by yourself. Liu Xinting said.

Cheng Zixuan, who felt that he really had to go a few times alone, thought about it and did not refuse Liu Xinting's help, nodded and said, "Then thank you, Tingting." ”

Because of the two of them, although Liu Xinting was not allowed to take too many things, Cheng Zixuan's luggage was still transported downstairs in one trip. Liu Xinting, who had been silent while waiting for the car, said: "Brother Cheng, will you come back to see me in the future and help me with my homework." ”

Cheng Zixuan thought about it, now that the laboratory has gradually moved on the right track, although he will be very busy in the future, he may not have time, so he nodded and said, "Yes, I am not the kind of person who is impersonal." Sister Liu has also helped me a lot, and I will come back to see you two often. ”

Is it just to look at me and my mother, Liu Xinting thought regretfully.

After watching Cheng Zixuan get into a taxi and leave far away, the girl unconsciously recalled the night a few months ago, and he left without looking back after helping herself, but her back was deeply imprinted in Liu Xinting's heart.

The girl raised her fist and cheered! Liu Xinting, you still have a chance! After cheering herself up for a while, Liu Xinting slowly walked home.

Cheng Zixuan, who returned to the laboratory, asked the oven: "Why does the research on ant medicine become 102%? ”

"Your Excellency Commander has ever heard of a gene fusion?"

"Gene fusion? You mean that the ant potion has genes from other species added to it. ”

"Yes, I have used my existing resources to make basic improvements and enhancements to the ant potion so that it can be more adapted to your body. ”

"Isn't there only an Abyssinian cat with the resources available? Cheng Zixuan wondered.

"Yes, the effect of the extra improvement is only 2% because of the large gap, and if you can find more creatures, you can improve it with any flask. ”

"Then why is the success rate of Abyssinian only 89%, oh, now 94%. Cheng Zixuan asked.

"Because the Abyssinian cat you bought is only 89% genetically pure, the reason why it can now rise to 94% is because of the potion that enhances you personally after analyzing your genes. That's why we increased the 3% match and the 2% match of the ant genes studied. The oven explained.

"That means that the potion is only 94% effective in the end. ”

"If we don't continue to add other research resources, it should be. ”

After Cheng Zixuan learned about the situation of the genetic medicine, he used the virtual console in the laboratory to look up the map information of the DL City Zoo, and quickly locked the location of the zoo.

"Oven, find out where the orangutans and monkeys are kept, and what the zoo is watching at night. ”

Soon a three-dimensional model of the zoo appeared on the console, with red and blue markers indicating where the monkeys and orangutans were housed, fortunately close to each other.

The monkey hall and the orangutan hall each have a rockery inside, and the outside is surrounded by tempered glass. It appears that in order to collect the blood of these two animals, it must be entered through the keeper's passage.

"Oven, mark the path from the staff passage to the zoo and how many locks are used for the staff passage, whether the door is opened with a physical key or electronic. ”

The three-dimensional map in front of him immediately transformed into a map that resembled a building plan, marked with a green road.

"Before you can enter the monkey house and the orangutan house, you need to go through two locks, the back door of the zoo is physically locked but it is usually unlocked because there is a security officer at the door. After entering the gate, passing by the locker room, there is also an electronic lock, which uses an electronic lock with an automatic door closer to prevent animals from escaping, and requires an employee card to enter. ”

I saw that there was a footprint mark on the map of the console, and after passing through the two doors, two arrows were divided.

"The room that the two arrows point to is where you need to enter the Monkey House and the Orangutan House. Both doors also use electronic locks with automatic door closers, which also require employee cards to enter. ”

"Did you say before that my watch has a certain hacking ability, and this electronic lock opens all the electronic doors of the zoo without triggering the alarm?" asked Cheng Zixuan.

"Absolutely. ”
