Outside the city of Huzhou's C district, inside the primeval forest, the polluted environment has caused the plants to begin to mutate.

Neither humans nor zombies dared to go deep into the forest.

Because unconsciously, you may encounter deadly dangers, and mutant plants are much more difficult to deal with.

Pet Ai and Lin Xu walked into the dim forest, and the leaves fell to the ground and spread into a withered yellow blanket, which would make a slight creaking sound when stepped on.

Pet Ai walked towards the place where the energy was sensed.

"Roar~" Where to go?

Lin Xu asked anxiously, his dark eyes scanning the forest.

"Shhhhh

This idiot, if he alarms the mutant plant, will have difficulty approaching its body, and it will be even more difficult to deal with.

Suddenly, there was the voice of Si Si Suo.

Pet Ai and Lin Xu felt their ankles grabbed at the same time, and then the two flew out in the next moment, and the trees quickly retreated.

In a moment, they were grabbed by the legs by the rattan and thrown towards a large mouth.

Is!

"Arson!" She shouted at Lin Xu.

Lin Xu's hands radiated scorching flames, wrapping around the thick vines like snakes, quickly spreading and burning.

As soon as he raised his hand, sharp ice edges appeared in the air, and he flew towards a large tree at a rapid pace, and slammed into the trunk of the tree.

Suddenly—

The vines that had grabbed their ankles and were burned by the fire loosened and quickly retracted to the trees.

The tree made a strange cry, screaming as if it was hurt.

The next moment.

More than a dozen bucket-sized vines suddenly appeared in the air, winding towards the two of them.

Pet Yi sneered, stretched out his hand, and like a raging wind passing through, the wind blade flew towards the tall mutant tree like a knife.

Lin Xu didn't show weakness and followed, and a ball of fire flew out of his hand and smashed on the thick vines that writhed like snakes.

The mutant tree shook wildly, and the vines smashed the surrounding trees to pieces, and the rumbling sound kept sounding.

Pet Ai flew over, and the ice in his hand condensed into a sharp knife, and thrust it fiercely. Cut the center of the tree to reveal the green nucleus in the middle.

The mutant tree sensed the mortal danger, and the vines all returned to wrap around the pet.

Pet Ai grabbed the crystal nucleus and pulled it violently, and the corners of her mouth hooked a cold arc: "Game over." ”

As if it had been frozen, the mutant tree suddenly stopped, and collapsed in an instant.

Pet Ai walked towards Lin Xu with a crystal nucleus full of energy.

"Here you go, eat it to upgrade."

This mutant tree has killed countless zombies and supernatural beings, and its crystal nucleus is full of powerful energy, and Lin Xu can upgrade to the seventh order after eating it.

"Roar, roar~" Thank you, Empress.

Lin Xu called out with emotion, and happily took the crystal nucleus.

"Don't thank me, if you don't level up, I'll kill you." Pet Ai said with a smile.

The expression of joy on Lin Xu's face froze, and he quickly ran away with the crystal nucleus.

The pet hooked her lips happily and walked slowly towards the city.

After two days, Tom and Jerry both successfully leveled up, but unfortunately they failed to upgrade to the seventh order, only to the sixth order.

Don't blame them, after all, not all zombies are as easy to upgrade as her, otherwise she, the villain, would be killed by cannon fodder.

Over the next few days.

Pet Elle asks Tom to take the zombies to start repairing the damaged base walls and repairing the city's electricity.

And Jerry led the zombies to take care of the environment in Huzhou and arranged the zombies in an orderly manner.
