In fact, the speed of the mutant wolf dog is faster than that of the normal Zhang Mu. After all, it can't fight alone. If the endurance is not as good as that of a human, it's too dignified to become a monster.

However, Zhang Mu is still very humane. When he runs, he will take out a handful of Yuanjing and animal nucleus and plug it for the mutant wolf dog. In this way, he believes that what Obsidian said is true. Zhang Mu can really continue to provide him with advanced energy.

Unlike obsidian, the attributes of the mutant wolf dog happen to be soil attributes, so it has no concern when taking the animal nucleus of the mutant wild monkey.

This mutant wolf dog has always been a loner. At most, it bullies small zombies, but does not dare to provoke groups of mutant animals, even if they are much weaker than it. Small mutant animals such as mutant mice can kill elephants after all.

Therefore, the strength of the wolf dog that has never taken the mutated animal core has improved by leaps and bounds, and the speed is not rising continuously. Zhang Mu is also very happy to feed it. The eccentric Obsidian has put forward opinions with Zhang Mu many times, and it is a little regretful to let Zhang Mu take it.

Obsidian looked at the mutant wolf dog with increasingly poor eyes. The goods swallowed all its share, but Zhang Mu blocked it back with a reason he couldn't refute.

Zhang Mu said a few simple words, and the Obsidian stopped squeaking. "Don't you have reached the bottleneck of the second order? Do you want these things or the second-order evolution potion that can make you advanced? If you choose these things, I can consider giving them to you, and then the second-order evolution potion can be used by the wolf dog. I think it's very obedient."

Obsidian is so angry that he really leads wolves into the house. This smelly dog has been fed by Zhang Mu in just a few days. Now he is so attentive that he will threaten to advance to the second level?

At this time, Zhang Mu, who was quiet a lot, fell directly on the back of the mutant wolf dog, and then fell asleep with his face close to his soft fur, happily dreaming freely. The wolf dog was very cooperative and paid attention to the bumpy frequency, so that the Obsidian saw it and scolded it for being worthless.

The wolf dog just showed his teeth at the obsidian, and didn't care about the threat of the obsidian.

In the past five days, the mutant wolf dog fully took nearly 40 first-order animal nuclei of the earth system. Except that the fur on the back was still soft and even more shiny, other parts were gradually covered by rocks, and the energy of the earth system slowly awakened on him.

Zhang Mu and his party returned to the highway they had passed before. Zhang Mu thought of the herd of mutant domestic pigs that had threatened his life before. He wanted to go over and have a look. By the way, he put the nuclei of these mutant animals into his bag. Because now he feels that the cost is too big. The wolf dog wants to eat, and the blood vine lotus needs to supplement different energy. Even the Obsidian sometimes can't see it, he wants a little as a snack. If Zhang Mu doesn't give it, he will spill it with Yuanrui.

As a result, the total number of animal nuclei in Zhang Mu's hands is only the last 20, which has shrunk by four fifths in the past five days. Zhang Mu is painfully dripping water. The cost of raising mutant animals is too large. No wonder those evolutionists with domestication ability have defected to the great power of the gathering place. Otherwise, they rely on their own skills, I can't feed these mutant animals who eat animal nuclear Yuanjing at all.

In fact, it's not like this. Future generations of domesticators don't feed so many animal nuclei to their mutant animals as crazy as Zhang Mu, mainly because it's too difficult to collect a large number of animal nuclei with the same attribute. Even if there are big rich people behind them, there is no way to dispatch them. After all, for evolutionists, this is also an urgent material and evolutionary energy.

But Zhang Mu's situation here is special, because an obsidian has a strong ability to absorb animal nuclei with various attributes, and a blood vine lotus is unscrupulous to absorb animal nuclei. The only normal mutant wolf dog also happens to need the energy of the earth system.

What Zhang Mu urgently needs now is the supplement of these animal cores. On the premise of not delaying the trip, Zhang Mu can only think of the mutant domestic pigs here. Although they look a little ugly, the animal cores in their bodies are real.

However, when Zhang Mu came to the familiar place of the truck chain, he was silly. The place originally occupied by dozens of pigs is now only flesh and blood, skeleton and feces.

Yuanrui and the mutant wolf dog were reluctant to approach. Zhang Mu had to get closer, cover his mouth and nose and observe carefully.

No one left? Did you run away? More stupid when your sanity is weakened? Don't you even have the least instinct?

Zhang Mu frowned, but soon he found something wrong.

A few scattered flesh and blood were stained with gray feathers that were not easy to find. Zhang Mu picked up one of the feathers and looked at it carefully in the sun.

Suddenly, his pupils coagulated and looked around in an instant.

"Is it a gray spotted vulture?"

"Unexpectedly, the opening of the zoo has been opened now. Did the animals run out by themselves?"

"Or has someone entered the zoo and let them out?"

Zhang Mu thought hard and put down his sleeves covering his mouth and nose. He didn't care about the lingering stench in the air, because in his memory, the zoo would not be opened by the advanced mutant animals for at least three months, which caused great harm to the gathering place at that time.

It must have been three months. Zhang Mu can't remember wrong. At that time, he had gone out to be an era merchant. When he came back, all the large gathering places he knew were attacked, causing heavy losses, resulting in excessive deaths. Many people he knew died in the city.

Zhang Mu originally wanted to deal with it when he returned to Luoyang City this time. After all, they all died of human beings, and he couldn't bear it. However, in just half a month, the gray spotted vultures have been released and can kill these mutant domestic pigs. It must be the elite who survived the crueler natural selection of the zoo.

Strength and intelligence must be superior.

Zhang Mu came back with a gloomy face and turned over directly on the back of the mutant wolf dog. He just said a word to Yuan Rui.

"Something may have happened in Luoyang!"

Yuan Rui looked at Zhang Mu's face and didn't dare to answer.

Zhang Mu directly urged the wolf dog to move forward at full speed, jumped directly on the collapsed carriage, and shuttled quickly.

I hope there are not too many things happening in Luoyang now.
