"All the delicious food I prepared for you is here. Take it with you when you leave."

"Yes, thank you, Auntie."

"Thank you, Mom."

"Thank you, Grandma."

With Chu Yunzhi and Chu Nanzhi around, the girls don't need to do these things, plus there's Xia Yiyang waiting for them at Huayang Mountain.

The van that everyone was preparing for the trip was parked in the yard. Chu Xingyue fastened Xiao Mianmian's seatbelt, Chu Jiaojiao sat in the passenger seat, and Chu Nanzhi sat in the back. Today, Chu Nanzhi was driving.

After saying goodbye to my family, the car set off.

Throughout the journey, Chu Mianmian chattered excitedly. Chu Xingyue and his siblings took turns talking to her. When the little girl didn't know something, except for Chu Yunzhi who was driving, the others took turns explaining it to her in words she could understand. The little girl kept exclaiming how amazing it was.

Huayang Mountain isn't too far from their Chu family's old residence, but it still takes more than an hour to drive there.

Xia Yiyang arrived last night. Chu Xingyue didn't let him go home, but told him to rest in the city. They met at Huayang Mountain this morning.

The journey was filled with laughter and joy.

"Sister, Jiaojiao." Xia Yiyang's voice could be heard not far away as soon as the car stopped.

Xia Yiyang, who had run up to Chu Yunzhi, saw him getting out of the car and Chu Nanzhi taking food out of the trunk.

"The brothers are back too?"

"Yes, we were on vacation too, so we came along."

"Uncle," Chu Mianmian, the little girl, exclaimed with delight upon seeing Xia Yiyang.

"Oh dear, Little Mianmian still remembers her uncle."

Xia Yiyang squatted down, picked up the little girl, and touched her forehead to hers.

"Mianmian has a very good memory; she remembers her uncle."

"You came alone?"

Chu Jiaojiao looked behind Xia Yiyang.

"Yes, of course, just one person. Who else would we need to bring on our family's spring outing with Xiaomianmian?"

"Oh, it's nothing." There was a hint of disappointment in his tone.

"Hey, wait, what are you thinking, little girl? I feel like there's something hidden in your words."

Chu Jiaojiao crossed her arms and didn't reply.

"He's mysterious and cryptic, and he only says half of what he means."

"What are you whispering about? Are you about to fight?" Chu Jiaojiao said, waving her fist in front of Xia Yiyang.

"He didn't say anything. Let's go, aren't we going hiking?"

After Xia Yiyang finished speaking, he picked up Chu Mianmian and started walking up the mountain.

"Come down, come down, Mianmian can walk by herself."

"Alright, alright, Mianmian can walk by herself."

Put Chu Mianmian down and let the little girl walk on her own.

"Brother, I'll get the things."

Chu Jiaojiao led Chu Mianmian in front, with Chu Xingyue following behind.

Xia Yiyang bypassed the two sisters and took the items directly from the two brothers.

"Xiao Yang, you can carry one. Nan Zhi and I will take turns carrying them."

"Okay, then just give it to me when you can't carry it."

"Okay, let's go."

The two brothers weren't being pretentious. They were just normal men in terms of physical strength, which couldn't compare to Xia Yiyang, who had a background in martial arts, and even less so to the two sisters. It was definitely impossible for the younger sister to carry things, but the younger brother could.

Xia Yiyang would definitely not suggest it, since this weight is less than the weight of his off-road gear.

With Xiao Mianmian and her siblings, the speed definitely wouldn't be fast.

The little girl was still excited, full of boundless energy, and felt like she could reach the top completely.

The five siblings walked and played, taking their time since they had little ones with them.

After walking for more than two hours, Chu Jiaojiao gradually took over leading Chu Mianmian, and the lunch boxes that should have been in Chu Nanzhi's hands were all in Xia Yiyang's hands. Xia Yiyang followed behind Chu Jiaojiao and Chu Mianmian, while Chu Xingyue and the twin brothers followed behind.

"Be careful!" Chu Xingyue quickly reached out and pulled Chu Yunzhi back.

"Thank you," Chu Yunzhi said apologetically, feeling a little embarrassed after being pulled.

"What's wrong?"

Xia Yiyang's voice came from ahead.

"It's okay, it's okay, I just tripped. Let's keep going."

"Brother, is something wrong? I noticed you seemed a bit distracted yesterday."

Chu Yunzhi hesitated, unsure how to begin.

"Brother, what can't you say? Have you forgotten who An'an is? An'an won't leak secrets to anyone else."

"I don't know where to begin."

"If you won't tell me, I will."

"Nan Zhi," Chu Yunzhi said with a hint of helplessness.

"We took this vacation because we ran into problems with the experiment. An'an, you don't know, some radicals at the higher-ups actually wanted us to conduct human experiments. It's absurd, isn't it? The problem is, my brother is starting to waver." Chu Nanzhi's voice wasn't loud, but the rise and fall of his chest showed his agitation.

“Nanzhi, it’s not what you think. I’m different from them.”

"How is it different? You were persuaded by them."

"Why can't I understand you?" Chu Yunzhi looked at his anxious younger brother with a bit of a headache.

"Brother Nan, you go after Jiaojiao and the others. I'll chat with Brother Yun for a while."

"Yeah, An'an, you should have a good talk with him. He's ruined his brain from doing research."

After saying that, she glared at Chu Yunzhi and turned to chase after Chu Jiaojiao and the others.

“An’an, you have to believe me, I’m definitely not that kind of person.”

Chu Yunzhi excitedly explained to Chu Xingyue.

"Brother, I believe you."

Chu Xingyue grabbed Chu Yunzhi's arms with both hands and looked directly into Chu Yunzhi's eyes.

Chu Yunzhi looked into the calm eyes before him and slowly calmed down.

After taking a deep breath, he spoke:

"I have already conducted experiments on laboratory animals, and the survival rate is extremely low. But I am willing to work hard for that one in ten thousand chance, which shows that my general direction is correct. Animals are more fragile than humans, and humans' strong will to survive will make the survival rate higher."

Where did you get that conclusion?

Chu Xingyue hit the nail on the head.

Chu Yunzhi was speechless.

"explain"

Chu Xingyue said sternly.

"I used my own blood to create the gene sequence for the experiment."

Do you know what consequences this will bring you?

That's insane.

Has Chu Yunzhi damaged his brain from doing research?

No wonder he looked so pale when he came back this time. At first, she thought he was just overworked. It turns out that there are still people who are willing to go crazy for experiments and research.

“If you weren’t my brother, I would have slapped you right now.”

“I know, An’an, I know you must have a way, right? I heard your name from the leader last time.”

Chu Xingyue remained silent. Her identity was no secret to those within the group who were interested, especially since Chu Yunzhi and Chu Nanzhi were her family. The mere mention of her name would be enough for them to assume it was her. After all, at her age, with her intelligence and achievements, it couldn't be anyone but their sister.

"Why do you think I would help you?"
