Zhao Chen quickly left the Boundless City and came to a deserted place.

Zhao Chen was ready now, and hurriedly said, "System, start traveling through time and space!"

【Ding, Starting......】

I saw that the repaired space-time key directly turned into a ray of light, enveloping Zhao Chen.

Then Zhao Chen found that he was already in the space-time tunnel, Zhao Chen seemed to feel a familiar breath, and gradually Zhao Chen saw the familiar light blue earth.

Soon, a white light that no one else could see quickly fell on the top of a high-rise building, thinking that he could still see the original prosperous and busy modern city, but the scene in front of him made Zhao Chen frown.

"System, is this really the earth? Why is it like this?" Zhao Chen hurriedly let the system analyze. In front of Zhao Chen's eyes were a piece of ruins, the once luxurious high-rise buildings were already unrecognizable, falling down, shattered! None of the houses were intact.

It's a completely apocalyptic scene, some buildings are wrapped around tall and rough rattans, and looking at the cars on the road, none of them are intact, and none of the roadside windows are intact, and it's very chaotic.

"Someone, isn't it right!" Zhao Chen looked at the shadow of a person, but found that his movements were really weird. Zhao Chen's eyes flickered, and the whole picture of this person appeared in Zhao Chen's eyes, and Zhao Chen couldn't help but be startled at this look!

"This is, zombies, is it the end of the world?" Zhao Chen couldn't help but exclaim. The zombie in Zhao Chen's eyes rolled his eyes, his skin was pale, his body was ulcerated, his clothes were bloody and tattered, or his whole body was covered in blood. It's exactly what a zombie looks like!

Zhao Chen moved slowly, and found the dilapidated signboard of this high-rise building, and he could clearly see the four words of Chuanzhou Building. Seeing this scene, Zhao Chen can be 100% sure that this is the earth, and this Sichuan Mansion can be said to be very familiar to him!

Today is your second year away from Earth!]

"What, it's only been two years!" Zhao Chen couldn't help but be surprised, he could be said to have been in the world of the Spirit Cultivation Continent for hundreds of years, and it had only been two years since he returned to the earth at this moment, why not make Zhao Chen very surprised, at this time, a figure appeared in Zhao Chen's mind: "Isn't that, my sister is still there!"

[Ding, on February 22, 2222, the earth's sky suddenly changed, the blood-red sky rained blood, countless extraterrestrial meteorites fell from the sky, directly hitting the ground, almost half of the people on the earth turned into zombies!]

[A rain of blood has changed all the animals on the earth, they have become ferocious and huge, and they feed on humans!

[Since that day, human beings have suddenly changed from the top of the food chain to the lowest food, becoming the object of hunting, and those who survive can only survive and struggle on the verge of death!]

"System, quickly check where my sister is now!Is she still alive!" Zhao Chen also listened to the information collected by the system, and hurriedly ordered. The world has become like this, and my sister doesn't know if she will live.

[Ding, I can't explore, but I search for a piece of information about Zhao Ruoruo!]

"Say it quickly. Zhao Chen couldn't wait to say.

[According to the news, a woman named Zhao Ruoruo successfully became an evolutionary a year ago!]

"There is no other information?" Zhao Chen said. That's too little news, isn't it?

[Ding, no.] 】

Zhao Chen couldn't help but shake his head, it seems that in the current situation, he will find his sister first, but unfortunately there are no clues now.

"By the way, system, what the hell did you just say that evolutionary?" Zhao Chen asked puzzled.

[Ding, the evolutionary is the mutation of human genes, and the real person becomes stronger, the higher the evolution level, the stronger the strength!]

This is Zhao Chen also understood, this is the same as cultivation, the higher the realm of cultivation, the stronger the strength. That sister is an evolutionary, which means that she has the ability to protect herself and should still be alive!

Zhao Chen couldn't help but think, and suddenly breathed a sigh of relief.

"System, what is my strength on the earth?" Since there is such a level division on the earth now, what is the strength of my current world, Zhao Chen couldn't help asking.

[Ding, nature is an invincible existence!]

Zhao Chen opened his personal information panel, and indeed his level bar was still invincible!

"Forget it, I don't want to do so much! Let's go to my own house first!" Zhao Chen shook his head and said, and then jumped down directly. The speed of landing was very fast, but Zhao Chen landed on the ground smoothly and made a slight falling sound.

Although the sound was very small, it still attracted the attention of the two zombies, watching Zhao Chen rush madly!

Seeing this, the corners of Zhao Chen's mouth raised, and with a wave of his hand, the two zombies were separated in an instant, and the two heads fell to the ground one after another.

"Well, there seems to be something in here?" Zhao Chen looked at the two corpses and muttered. With a slight bend of his fingers, a pitch-black thing flew directly into Zhao Chen's hands in the two corpses.

Looking at the pitch-black spar-like thing in his hand, Zhao Chen thought of something: "Is this the corpse core?" Zhao Chen felt a strange energy from this corpse core.

I saw Zhao Chen's fingers pinched slightly, and the corpse core changed into ashes, and the energy in it was also emitted in the air and disappeared.

Looking at the corpse of this zombie up close, Zhao Chen still felt slightly disgusted, and quickly left the place.

Walking according to the familiar route in his memory, he soon came to a community, but there was a ruin in front of him, Zhao Chen couldn't help but sigh: "There is no home, I want to buy a house, I don't know how much hard work I have paid!"

Just as Zhao Chen wanted to leave, he suddenly felt a killing intent, and soon Zhao Chen locked on to this killing intent in a darkness.

There were two green lights in the darkness, and a cat came out. You can see that its claws have become very sharp.

"Isn't that the Colat cat raised by Uncle Wang next door?" Zhao Chen looked at the familiar cat and couldn't help but say, thinking that Uncle Wang next door didn't show off his Colat cat, as for why Zhao Chen recognized this cat at a glance, it was because there was a scar next to the cat's eyes, which seemed to be a birthmark. So it's also easy to identify!

I didn't expect pet cats to mutate.

The Colat cat tiptoed, approaching Zhao Chen step by step, and pounced on Zhao Chen, Zhao Chen saw the shadow of the Kotla cat flashing, and came to his side.

The Kotra cat directly stretched out its claws and slapped at Zhao Chen's head.

"Good guy, this is killing me!" Zhao Chen snorted coldly.
