He and the obsidian worm spent a full hour on this meal, playing with it and eating it. Zhang Mu didn't dare to rush into the sea of ​​fire rashly, so he took a sausage from his backpack and shook it up and down, teasing his little beetle out of boredom to kill time.

Gradually, the night grew darker.

Zhang Mu stood up, quietly looked at the scenery in the distance, and stuffed the last piece of bread in his hand into his stomach.

Alas, this is the downside of strengthening the body in advance. It consumes too much energy, and the amount of energy that needs to be replenished will gradually become a huge number. Fortunately, there is this merchant ring, otherwise such a large mountaineering bag, even if Zhang Mu fills it up, it will only be enough for one meal for him now.

Pack up and leave.

Zhang Mu casually picked up the little beetle playing on the ground, put it on his shoulder, and looked at the place in the distance where the gas station used to be turned into a mess.

He knew that he was about to get his first great fortune after his rebirth.

The man and the bug slowly walked out of the shelter and trotted towards the ruins of the gas station where the flames had been extinguished.

"Here, you are in charge of this side. Eat as much as you can. Everything you can eat is yours."

Zhang Mu generously designated an area for the obsidian worm and let it forage for food on its own.

In fact, Zhang Mu's heart was bleeding, but who could blame him for the fact that the Obsidian Worm was already bound to Zhang Mu's blood? The power of the Obsidian Worm was now also a part of Zhang Mu's strength growth, so the stingy man had nothing to be reluctant to give up.

As long as there is any opportunity to enhance his strength, Zhang Mu will not miss it.

Although he did not have the ability to tame a mutant beast in his previous life, after all, even the lowest level mutant beast requires an evolver with the ability to tame and evolve it to have a slight chance of success through constant attempts.

However, Zhang Mu in later generations had heard the merchants he had traded with mention it several times, because some animal trainers needed a large amount of crystals and exotic materials to train mutant beasts, and obtaining them from their Era Agent merchants was a stable way to obtain resources.

When Zhang Mu heard the number revealed by his colleague, he felt a sense of emotion. It turned out that raising a mutant beast required so many Yuan Crystals as a price.

However, as long as you can successfully tame one, the price after reselling it will rise rapidly, which is really a huge profit.

Zhang Mu was not famous at that time, and the Yuan Crystals he had stored were not enough to fill the gaps between the teeth of these high-level animal trainers. Naturally, no one came to him to purchase goods, so he didn't know the specific situation and just listened for fun.

However, now Zhang Mu finally saw what it meant to really burn money.

When Zhang Mu just ordered the Obsidian to find the Yuanjing to eat, the little beetle lying on Zhang Mu's shoulder, unable to hold back any longer, suddenly shot out in the direction Zhang Mu said like a cannonball, creating ripples in the air, and even the transformation time was much faster than usual.

Under Zhang Mu's stunned gaze, the sturdy obsidian worm began to fly flexibly at a low altitude. It stretched out its small claws and poked accurately, picking out the Yuan Crystals preserved in the charred wreckage on the ground and throwing them into its mouth. Its efficiency was extremely high.

During the time when Zhang Mu was in a daze, the agile obsidian worm had already eaten at least fifty Yuan Crystals. You know, these are not ordinary first-level Yuan Crystals, they are all second-level Yuan Crystals with ten times more energy.

Zhang Mu felt a little scared. What kind of monster was this that signed a blood contract with him? It could actually absorb so much energy across levels, and it didn't even look like it was saturated.

Looking at himself again, it took him five minutes to pick out two Yuan Crystals from the remains of several zombies that had turned into a ball. Comparing this efficiency, Zhang Mu simply stopped digging and waited for the Obsidian Worms to eat their fill and then work for him.

About ten minutes later, under Zhang Mu's gloomy gaze, his obsidian worm finally ate its fill. Although it looked a little reluctant, it stopped taking out the Yuan Crystal.

A giant bug as tall as a man staggered back to Zhang Mu.

Indeed, the number of them had an effect. Zhang Mu felt that the already fat body of the obsidian worm had become even thicker, and its claws and teeth had inexplicably increased by about two centimeters. Most importantly, the dark golden stripes on its head began to increase. The pattern that was almost invisible without careful observation had now become a little clearer.

"How much did you eat?"

As if it was too excited, the Black Obsidian didn't seem to notice the strangeness in Zhang Mu's tone and answered stupidly.

"Master, Xiao Hei has absorbed 100 portions of energy. He is so full that he can't eat anymore."

Just when the Obsidian Worm was about to shrink and return to Zhang Mu's shoulder to rest, Zhang Mu snorted coldly, "You want to sleep after eating? It's not that simple. Hurry up and pick out the remaining Yuan Crystals for me.

Why are you still standing there?

Why don't you go now? Do you want me to kick you?"

The Obsidian Bug then noticed Zhang Mu's distressed look, as if he had eaten too much all at once. Afraid that Zhang Mu would get angry, he quickly did as Zhang Mu said.

The obsidian was flying low in front of us.

Since he was only responsible for picking out the Yuan Crystals, he increased his speed. Zhang Mu was almost unable to pick up any more just by following behind.

One, two... ten... a hundred... picking them up quickly like this, Zhang Mu and Obsidian had already taken out all the Yuan Crystals from the necks of the zombies covering most of the ground in the gas station.

Nearly five hundred Yuan Crystals had already filled Zhang Mu's backpack. The Obsidian Worm picked them up and ate a few more, but Zhang Mu pretended not to notice.

Just when Zhang Mu was about to put everything in his backpack into the ring and use the empty bag to continue collecting the remaining crystals on the ground, his obsidian worm suddenly stopped moving. The small wings on its back began to vibrate at high speed, conveying a feeling of uneasiness and anxiety to Zhang Mu from the heart, and its small eyes stared straight at the direction behind the ruins.

What is this green light?

Looking at the direction the obsidian was staring at, Zhang Mu didn't notice it at first, but slowly, the dots of green light began to increase. Zhang Mu saw clearly what it was and instantly took a breath of cold air.

The green light actually came from the eyes of hundreds of mutant mice.

When the green light reached a certain density, these green dots began to move rapidly.

Zhang Mu subconsciously wanted to run away, but suddenly realized that they were not coming for him. They all pounced on the charred zombies and started biting them. Wherever they passed, not even a bone was left. In their eyes, Zhang Mu and the obsidian worms were not even enough to fill their teeth.

"My money!"

Zhang Mu reacted and shouted in agony. At this time, a large group of mutant rats were attracted by the sound Zhang Mu accidentally made.

I didn't feel anything just now, but now the feeling of being stared at by hundreds of mutant rats at the same time is really uncomfortable.

"Okay, you guys are so powerful, I can't afford to offend you, so I'll run away, Xiao Hei.

The wind is strong, hurry up."

Zhang Mu was frightened by being stared at, so he turned around and ran. After hearing Zhang Mu's command, the Obsidian Bug moved even faster than him. It shrank in a flash and rushed to Zhang Mu's shoulder, asking Zhang Mu to run with it.

The mutated rats still did not follow. After all, the meat of the zombies and the weight of these second-level crystals were too great, and Zhang Mu's meat was not good enough in their eyes.

"It turns out that the debugging period is so difficult. No wonder few people in the world dare to wander around during the debugging period."

Zhang Mu walked towards the warehouse while cursing.

However, this is the normal behavior of low-level mutants, group hunting. Zhang Mu's obsidian worm is really special.
