"The boundary of chaos is the edge of the primitive world. Because the evolution is not perfect, it belongs to the beginning of the world. There are many unknown dangers in it. For anyone, it is a very dangerous place!" Mu Feili explained, chaos. The boundary, even their lucky children, are unwilling to go there, because inside, their lucky power has no place to play.

"That capable person escaped to the border of chaos. Did you know that we were going to kill him?" Xiao Ai'ai asked with some confusion.

"Whether it is or not, it's a bit of trouble now. If that guy is allowed to continuously improve his strength in the Chaos Boundary, he will definitely reappear in the world by then." Mu Fei left the road, his eyes with indescribable solemnity.

"Let's go in!" Xiao Aiai said solemnly.

"You can imagine that once we enter the boundary of chaos, even we may belong to chaos." Mu Feili said in a deep voice. Generally speaking, their lucky sons cannot die, but there is one exception, that is, Chaos boundary, the place where they killed the ancient evil beasts in the first place is also the Chaos boundary, otherwise the ability of the ancient evil beasts would never be killed.

However, even if the ancient evil beasts died within the boundary of chaos, they still possessed and do evil on humans from time to time, which is enough to prove the horror of the ancient evil beasts.

"If we really wait for Ying's resurrection, we still need to go to the chaos boundary." Xiao Aiai said, Ying's resurrection, they will definitely find their revenge, they will face it sooner or later.

Hearing Xiao Ai'ai's words, Mu Feili's expression instantly collapsed, and said, "I really don't want to go to the border of chaos. Let's just leave other people alone."

"As much as possible, we must bear much responsibility." Xiao Ai'ai gave Mu Feili a pale glance. They are lucky children and have the responsibility to protect the creatures of the primitive world. If they cannot save themselves, they will be lucky children. , Will gradually be deprived.

"Hey." Mu Feili could only sigh, and suddenly looked at Qianmei Yilian and said: "Sister, you will appear when Xiao Chen should appear, then where is he now?"

She was not concerned about Xiao Chen, but the old man in Xiao Chen's body.

"Don't worry, he will appear when he should appear." Qianmei Yilian replied with a smile.

"Okay, we should start." Xiao Aiai said.

"Let's go." Mu Feili said helplessly.

The chaotic boundary is located on the edge of the primitive world. Because there are various unknown dangers here, the primitive power is not strong, so few people set foot.

A few days later, Xiao Aiai and the others came to the edge of a desert. In the desert, there was flying sand and rocks. The entire sky was desert, gray, and it looked terrifying, giving people a very uncomfortable feeling.

"This is just the edge of the chaotic boundary. When going inside, the weather is even worse." Mu Feili sighed. She was very reluctant to come here. The bad weather alone made her feel bad.

"Don't complain, the chaos boundary is very large. We don't know when we can find the capable person, but there is no time to continue wasting here." Xiao Aiai said, saying that he had stepped into the desert.

It was just that she had just stepped into the desert, and suddenly not far from her, flying sand and rocks, a tornado suddenly appeared, accompanied by the appearance of the tornado, and the roar of beasts.

"No, we are the lucky ones. When did our luck become so bad." Mu Feili looked at the tornado and suddenly widened his eyes.
