The mutant wolfhound's speed is actually a bit faster than Zhang Mu's normal speed. After all, he can't win in a one-on-one fight. If his endurance and speed are not even as good as a human, then it would be too undignified for this mutant beast to be like this.

However, Zhang Mu was still very humane. While running, he would take out a handful of Yuan Crystals and mixed them with beast cores and feed some to the mutant wolfhound. This made it believe more that what the Obsidian Worm said was true, and that Zhang Mu could really provide it with energy for advancement on a continuous basis.

Unlike the Obsidian Worm, the mutant wolfhound's attribute happens to be earth-related, so it has no concerns at all when taking the mutant wild monkey's beast core.

This mutant wolfhound has always been a loner, and at most it would bully small groups of zombies. It has never dared to provoke those groups of mutant beasts, even those that are much weaker than it, such as small groups of mutant rats. After all, a large number of ants can kill an elephant.

Therefore, the wolfhound, which had never taken the mutant beast core, made rapid progress in strength, and its speed was constantly increasing. Zhang Mu was also very happy to feed it. The biased Black Obsidian had already mentioned his opinions to Zhang Mu many times, and it was a little regretful that it had let Zhang Mu accept it.

The obsidian worm looked at the mutant wolfhound with increasingly hostile eyes. The creature swallowed up all of its food, but Zhang Mu blocked it with a reason that it was unable to refute.

Zhang Mu said a few simple words and the Obsidian fell silent. "Aren't you almost reaching the bottleneck of the second stage? Do you want these things, or the second-stage evolution potion that can help you advance? If you choose these things, I can consider giving them to you, and then give the second-stage evolution potion to the wolfhound. I think it is quite obedient."

The Obsidian Bug was so angry that he almost died. He was really inviting a wolf into the house. This stinky dog ​​had been fed by Zhang Mu for just a few days and had become completely devoted to him. Now he was constantly showing his affection to him, and he was even threatening to let it advance to the second level?

Now, Zhang Mu, who was much quieter, lay directly on the mutant wolfhound's back, and then fell asleep with his face pressed against its soft fur, happily and comfortably having a sweet dream. The wolfhound cooperated very well and paid attention to the frequency of the bumps, which made the Black Obsidian see it and angrily scolded it for being useless.

The wolfhound

He bared his teeth at the Obsidian Worm, not caring about the threat posed by the Obsidian Worm at all.

During the five-day journey, the mutant wolfhound consumed nearly forty first-level earth-type beast cores. Except for the fur on its back which remained soft and even became more shiny, other parts of its body were gradually covered by rocks, and the energy of the earth-type slowly awakened in its body.

Zhang Mu and his group returned to the highway they had passed before. Zhang Mu remembered the herd of mutant domestic pigs that had threatened his life before, and wanted to go over to take a look and collect the nuclei of these mutants. Because now he felt that the expenses were too high, the wolfhounds needed to eat, the blood vine lotus needed to replenish different energies, and even the obsidian insects sometimes couldn't bear to eat some as snacks, and if Zhang Mu didn't give them anything, they would get mad at Yuan Rui.

As a result, Zhang Mu now only has the last twenty beast cores in his hand. In the past five days, the number has shrunk by four-fifths. Zhang Mu is heartbroken. The cost of raising mutant beasts is really too high. No wonder those evolvers with the ability to tame beasts have joined the big forces in the gathering place. Otherwise, they would not be able to feed these mutant beasts that feed on beast core crystals with their own abilities.

In fact, it is not like that. Tamers in later generations did not feed their mutant beasts so many beast cores as crazy as Zhang Mu. The main reason was that it was too difficult to collect a large number of beast cores of the same attribute. Even if there were wealthy people behind them, there was no way to mobilize them all. After all, for the evolvers, these were also urgently needed materials and evolutionary energy.

But Zhang Mu's situation was rather special, because a Black Obsidian Worm had a very strong ability to absorb beast cores of various attributes, and a Blood Vine Lotus absorbed beast cores even more unscrupulously. The only normal mutant wolfhound happened to need earth-type energy.

What Zhang Mu urgently needs now is to replenish these animal cores. Under the premise of not delaying the journey, the only thing Zhang Mu can think of is the mutant domestic pigs here. Although they look a bit ugly, the animal cores in their bodies are genuine.

However, when Zhang Mu arrived at the familiar place where the trucks were linked together, he was dumbfounded. The place that was originally occupied by dozens of domestic pigs was now filled with only flesh, bones, and feces. It was a mess.

Yuan Rui and the mutant wolfhound looked disdainful and didn't dare to approach, so Zhang Mu had no choice but to move closer, covering his mouth and nose and observing carefully.

There was not even a single one left? Did they run away? Did they become even dumber after their intelligence was weakened? Did they lose even the most basic instincts?

Zhang Mu frowned, but soon he realized something was wrong.

There were a few grey feathers on the scattered pieces of flesh and blood that were not easy to spot. Zhang Mu picked up one of the feathers and examined it carefully in the sunlight.

Suddenly, his pupils condensed and he raised his head and looked around.

"Is it a gray buzzard?"

"I didn't expect the zoo entrance would be opened now. Did the animals escape on their own?"

"Or has someone already entered the zoo and released them?"

Zhang Mu thought hard and even put down the sleeves that covered his mouth and nose. He didn't care about the stench in the air at all. Because in his memory, the zoo would not be opened by the mutant beasts that had advanced at least once every three months, causing great damage to the gathering place at that time.

It must have been three months. Zhang Mu would not be wrong. At that time, he had already gone out to do the mission of the Epoch Merchant. When he came back, several large gathering places he knew were all attacked, causing heavy losses and resulting in excessive casualties. 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, those who died were all humans, and he couldn't bear it. However, it was only half a month, and the group of gray vultures had been released. Those who were able to hunt these mutant pigs must be elites who survived the more cruel natural selection in the zoo.

Strength and intelligence must also be top-notch.

After Zhang Mu came back, he had a gloomy face and directly climbed onto the back of the mutant wolfhound. He only said one sentence to Yuan Rui.

"Something might have happened in Luoyang City!"

Seeing Zhang Mu's gloomy expression, Yuan Rui did not dare to respond.

Zhang Mu urged the wolfhound to move forward at full speed, leaped over the collapsed carriage with great force, and shuttled back and forth at a rapid speed.

I hope that not too many things will happen in Luoyang City now.
