What's wrong with being cold-blooded in the end times? Anyone who messes with my wife will die.

"Roze, look—"

In the early morning of June, the air was filled with the unique warm and stuffy atmosphere of early summer. The dazzling sunlight shone through the gaps between the leaves, casting mottled shadows on the ground, swaying gently in the wind.

Luo Ze leaned against the trunk of the old locust tree, closed his eyes and silently recited ancient poetry, ignoring Kong Sisi's excited call.

"Luo Ze!" Kong Sisi saw that Luo Ze ignored her, closed his eyes, and moved his mouth silently. She shouted again in dissatisfaction, "Luo Ze, look at me!"

Luo Ze was confused by her continuous shouting and had to open his eyes helplessly. He saw that Kong Sisi's whole body was wrapped in a layer of blue ice, which even condensed into the shape of armor.

"I asked Nandan to teach me." Kong Sisi looked at Luo Ze who was a little stunned, and felt a little proud in her heart, "How is it?"

Just a week ago, Kong Sisi, under the instruction and training of Nan Dan and Kong Lian, was able to control her ice ability more accurately, and she also gave her two "teachers" satisfactory results - she upgraded from green ability to blue ability.

From Fu Ying's point of view, it is not difficult for a green alien to upgrade to a blue alien, but for a young alien like Kong Sisi, the upgrade speed is far beyond most of the aliens in the world.

"Sisi is very talented." At that time, seeing Kong Sisi's level up, Song Shu said, "This child has a bright future."

Fu Ying just said one simple sentence.

“Belief is important.”

Song Shu understood: "You mean she wants to protect Luo Ze's belief."

Fu Ying nodded.

"Sisi, you're awesome." Luo Ze stood up and walked over to check the ice armor on Kong Sisi. He noticed the dense and fine spikes on the surface of the ice. It was hard to see clearly from a distance. "Sisi, what's on that?"

"It's my weapon." Kong Sisi saw Luo Ze reaching out to touch it, and said with a smile, "Sister, you won't get hurt if you touch it, I will put it away, but if someone else touches it, they will bleed."

She was right. When Rose touched the surface of the ice, all the spikes had disappeared and that spot became very smooth.

"What kind of weapon is it? Is it just for defense?" Rose asked her.

Kong Sisi shook her head: "Of course not."

She gently pushed Rose away, walked toward the street, faced the abandoned storefront, raised her hands, and the color of her ice armor instantly became richer. A strong chill emanated from her body, forming mist in the air.

In that instant, all the spikes on Kong Sisi's armor popped out, and she rushed forward at an extremely fast speed, piercing into the concrete wall like a bullet!

Luo Ze ran over and tried to pull one out, but the spike was completely embedded in the concrete wall and could not be pulled out at all. Kong Sisi directly controlled an ice spike to move outside the wall.

As the ice spike moved, Rose discovered that it was actually longer than his forearm. The spike was thin and long, and had barbs on both sides, which scraped off a lot of cement debris.

It is hard to imagine what a tragic scene it would be if these ice spikes pierced into the human body.

Luo Ze was still frightened. She looked at Kong Sisi, who was full of joy and expectation when looking at her, and considered her words: "Well... Sisi is great, very good."

Kong Sisi burst into laughter and threw herself into her arms: "I can protect you, Luo Ze."

Luo Ze touched her head and made an unexpected discovery.

"Sisi, have you grown taller in the past few months?"

Kong Sisi touched the top of her head and was very happy: "Really? Dad said that girls develop faster, and it is normal to grow taller now."

Luo Ze compared her size with his own and felt a little jealous.

How come he is almost as tall as me? No, I have to go find Sister Squirrel and ask her if she has any tips on how to grow taller.

Luo Ze said: "Let's go back."

Kong Sisi grabbed her hand, and the ice spread from her hand to Luo Ze's hand. Luo Ze did not retreat, but just lowered his head and stared.

Soon, a thinner set of ice armor appeared on her body. Kong Sisi looked at it and was very dissatisfied: "It's still not enough. The protection is not strong enough. I need to work harder."

"You've worked very hard." Luo Ze said seriously, "Don't overwork yourself, Sisi."

"Not enough, Luo Ze, I still need to evolve to purple level." Kong Sisi said firmly, "I want to protect you and daddy. Look at how powerful Fu Ying is, I want to be as strong as her."

Luo Ze: “…”

She breathed in lightly, her eyes a little warm.

The armor on Kong Sisi suddenly disappeared, and the armor on Luo Ze also disappeared. Kong Sisi's face changed, but she quickly reacted: "Sister, you are using your ability to shield me again."

"We should go back to study." Luo Ze held her hand, "Uncle Kong said we should read more and develop good character."

Kong Sisi curled her lips: "Is it useful? This world is full of people who kill each other. Maybe their personalities were good before, but they changed after the zombies appeared."

"Oh, that's their business. We have to learn our own thing. Sisi, I will always be with you, so you won't feel tired."

The two walked towards the southern inner wall. On the way, they saw several beast-shaped people running wildly on the road. Kane and Mu Wenxuan were practicing their abilities. Mu Wenxuan's ability could only turn stone into gold, and he was still a white one, and had not successfully upgraded yet. Kane was the same, still a green one.

After knowing that Kong Sisi had been promoted, everyone in Building No. 1 celebrated for her with a mixture of envy and joy, which greatly inspired others to want to be promoted.

When Kong Sisi passed by Kane and Mu Wenxuan, she casually shot out an ice spike and controlled it to penetrate the gold nugget that Mu Wenxuan had just lit up.

Kane waved his hand: "Children are not allowed to make trouble. Mu Wenxuan, look at yourself, then look at Kong Sisi, you have to work hard, young man——"

Mu Wenxuan: “Let’s encourage each other.”

Kane: "Don't speak ancient language, I don't understand."

Mu Wenxuan: "Don't pretend to be a foreign guest."

Kane: "I'm a foreign guest, okay?"

"..."

"I don't understand why they can't upgrade." When the two walked to the bottom of the south inner wall, Kong Sisi said lightly, "They are still not working hard enough."

"Sisi, sometimes you can't succeed just by working hard." Luo Ze explained, "Sister Fu Ying said that for psychics to level up, they also need to rely on luck to unleash their potential."

"Then I have both luck and potential." Kong Sisi said confidently, "Just wait, Luo Ze, I will definitely reach the purple level this year."

Luo Ze didn't quite believe it, but he didn't want to disappoint her: "Then you should have a good rest and protect yourself. I will supervise you."

Kong Sisi grinned and said, "I know that my sister loves me the most."
