Shi said softly: "I will keep these crystal nuclei first, and then I will give them to you later." ”

Liu Yiyi did not refuse: "Thank you, sister~"

Shi said softly: "Then let's go." ”

Liu Yiyi nodded, and the two held hands, continued to move forward, and successfully left the Yican Research Room.

On the way, they encountered a lot of zombies, and Shi Qing wanted to do it, but considering the time limit of Liu Yiyi's stealth ability, they chose to give up.

After all, I have already got the big head, and then I have to make this small profit and lose a lot because of the small loss, and some of the gains outweigh the losses.

When Shi Qing and Liu Yiyi rushed back, they were mentally attacked, and immediately covered each other's heads, seeing that their hands were about to be released, Shi gently bit his lip and quickly returned to the car with Liu Yiyi.

Liu Yiyi was sweating profusely, but insisted on not handing it over.

If it was during her total victory, she would definitely be able to block the mental attack, and the reason why she couldn't resist it at this time was because the ability was too badly depleted.

Shi Qing was very worried about her situation, took out a handful of first-order crystal nuclei for Liu Yiyi to absorb, and saw that her face was better, so she was relieved.

For Liu Yiyi, the stealth ability is good, but it is not easy to advance, because she can only absorb the first-order non-attribute crystal nucleus, and the crystal nucleus of the higher level above cannot absorb it at all.

The zombies with stealth abilities are terrifying to think about, not to mention, they haven't encountered zombies with stealth abilities now, so it is not easy for Liu Yiyi to advance to the second order.

"Yiyi, how are you now?" When he opened the car door gently, he saw Ji Moyan and the others dealing with zombies in dirty white coats, while Yanchen and Yanyang's convoy were watching from the side, obviously trying to pick up the leak.

frowned slightly, and after watching the battle for a while, he felt the movement behind him, looked at Liu Yiyi and hurriedly asked.

"Sister, I'm fine." Liu Yiyi also noticed the situation outside, and was a little worried about her brother: "Sister, I want to see my brother." ”

Shi Qingqing also wanted to see her son, but Liu Yiyi needed someone to guard her, so she held back and waited patiently for her to recover: "Okay, you follow me incognito, let's go to that RV." ”

Liu Yiyi nodded, her face was pale and invisible, only at such a distance, she could still get through.

Shi gently got out of the car and walked quickly to the RV that she had enclosed with a water chain, Yan Chen and Yan Yang noticed Shi Qing's movements, just glanced at it and looked away.

Shi Qing didn't know what happened during the time she and Liu Yiyi left: "Xiao Heng! How are you? After getting into the car, he reached out to hug his son, and his eyes turned red.

Shi Zhiheng was hugged a little tightly, he hadn't seen his mother for so long, he was a little scared: "Mom." ”

The mother and son hugged each other, Liu Yiyi's figure was revealed, and seeing that her brother was fine, Liu Yiyi breathed a sigh of relief, found a place to sit down, and continued to recover her abilities.

Seeing this, she hugged her son and waited quietly, and at the same time used the water crystal nucleus to restore her ability, but she was a little seriously injured, and she used the fourth-order water crystal nucleus beyond this level, and at this time, many places in the body were damaged, and the ability could not be called for the time being.

Now the ability is her only means of attack, and if she can't use it, she'd better rest on the sidelines.

As for the fifth-order zombie war outside, even if she wanted to manage it, she was powerless......

"Mom, is Dad back?" Shi Zhiheng's immature voice sounded, Shi gently let him go, and touched the somewhat messy hair: "Xiao Heng misses his father?" ”
