While Zhang Mu was still relishing the harvest of this hunt, obsidian had solved the remaining dozens of first-order zombies and rushed back to Zhang Mu to take credit.

"How to say, it's OK this time?"

Zhang Mu's heart heard a voice of obsidian, which was full of arrogance. He also felt angry and funny, but he couldn't say anything about obsidian. After all, obsidian's warning did give him time to react at the first time.

So unexpectedly, Zhang Mu didn't move his hand to obsidian. He didn't even refute it. He smiled and said, "it's really thanks to you this time. You're great. I owe you this bill first. After tonight, I'll settle it for you and you'll get what you want."

Zhang Mu then muttered in a low voice, "I really didn't learn anything else. I took the opportunity to give full play to my ability to raise my value. I haven't heard anyone say that after signing a blood contract with the mutant beast, it will be imperceptibly influenced by the master's character.

Bah, no, I'm not like Zhang Mu. "

Zhang Mu, who can't remember this memory, doesn't think about it anymore. With a big hand, he casually said to obsidian, "you first pick out all the yuan crystals in the zombies on the ground and put them on the corpses. Wait for me to collect them. If there are zombies involved, it takes too much time."

Although it was clear that there were nearly 1500 zombies on the ground, obsidian was completely attracted by the bad check described by Zhang Mu. He did his work without ambiguity and didn't even complain. He began to fly diligently to the end of the street. Starting from the first zombie, he accurately and quickly took out the Yuan crystal behind the neck of each zombie.

After all, Zhang Mu promised it, but a big cake that can make it advance to the second level and become an alien. If it is allowed to evolve by itself, it is estimated that it will take at least a month, maybe more than that. It requires a large number of first-order peaks and animal nuclei that meet its attributes to be promoted, which is more difficult.

In fact, Zhang Mu knows that era merchants have not developed the system function of exchanging variant animal cores with different attributes, but Zhang Mu is not cheating obsidian, because he thought for a long time and thought it was time to take that thing out and use it on obsidian.

Yes, it's the bottle of second-order evolution medicine in Zhang Mu's hand!

Although this medicine is marked by era merchants to enable human first-order evolutionists to greatly improve the success rate, it is also suitable for the evolutionary needs of mutant animals.

The only second-order evolution potion bought from era merchants is the reason why many evolutionists flock to it in future generations because it has no attributes!

In other words, evolutors and mutant beasts of any attribute can use this purest evolutionary medicine to improve their success rate of promotion. It is the safest and most harmless. Moreover, if it is a two attribute or three attribute evolutor, it can also share the mysterious energy that can catalyze evolution.

Because unless the era store opens the function of exchanging mutated animal nuclei of any attribute one year after the end of the world, in most cases, if the evolutors in the early end of the world can't exchange animal nuclei that meet their attributes, they will take risks to absorb animal nuclei of the same level that are inconsistent with their attributes to refine themselves in order to obtain powerful power after advanced.

Although weak humans have a 70% chance of exploding and busy in this situation, it is difficult to find the peak animal core at the same level as themselves. In order to increase the probability of these 30% to another higher level, many evolutionists without background will choose to fight.

After all, further advancement means that we can get strong strength, respected power and our own security will be guaranteed. Such temptation is too great in this man eating end of the world.

Even in a large gathering place, in the year before the end of the world, there were no era agent merchants to make large orders with them. In fact, the rare peak animal cores of the same level they hoarded were only enough to meet the hands of those who held real power at the top of the pyramid.

Therefore, once an era agent merchant is found to sell the legendary perfect evolutionary medicine, he will buy it at all costs, and may even stare at the merchant with a treasure.

If there is no strong background, there is no era agent businessman who dares to sell this generously. They still understand the truth that every man is innocent and vindicates his crime, and they generally use it for their own use. Only their strong strength can be relied on to get enough confidence to match when trading, otherwise they will be swallowed by people and even waste.

This is what Zhang Mu exchanged for almost all his savings, but now he decided to buy another bottle of second-order evolutionary medicine after observing the era general goods list of businessmen in Xi'an City tonight. He decided to give the bottle in his hand to Obsidian first.

Because he felt that if he evolved to the second level without any awakening evolutionary ability, his agility and strength would be qualitatively improved, while others would not change at all. This is the sadness of his ordinary evolutionist who has no evolutionary potential.

However, if this bottle of second-order evolution medicine is used by obsidian, which has reached the peak of the first-order, it is likely to break through the second-order in one fell swoop with the accumulation of various attribute animal nuclei it has eaten before.

The reason why Zhang Mu doesn't use Obsidian now is different from human beings. The advanced process time of mutant animals is uncertain for different species. At present, Zhang Mu needs obsidian, at least to protect Yuanrui and find large zombies.

If the transaction with the era merchants in Xi'an city can be successfully completed, Zhang Mu can exchange new era general goods that can greatly enhance himself, and the Obsidian can enter an advanced sleep.

No more thinking, Zhang Mu took Yuanrui from the starting point of obsidian insects to start the collection process. His right hand hung low and opened his era merchant ring. As long as Yuanjing, which was pulled out by Obsidian insects near him, was not involved in flesh and blood, they poured into the black hole where the ring on Zhang Mu's hand expanded.

This is also a hidden benefit after swallowing a new era merchant ring. Zhang Mu's own one can be opened for up to ten minutes each time.

Obsidian took out Yuanjing at almost the same speed as Zhang Mu's walking all the way to collect scattered Yuanjing. In only eight minutes, Zhang Mu swept away all Yuanjing on the ground. As for those zombies, Zhang Mu was not interested at all.

Obsidian now has a high vision. He doesn't eat this ordinary first-order zombie meat at all. He also dislikes its taste. His mouth has been picked up by Zhang Muyang. He completely forgot how he enjoyed eating at that time. As for the blood rattan lotus, it is even more cold. This kind of blood and meat with too little nutritional value and too low energy storage is not thin enough to stretch out the rattan to devour.

Looking back at the messy commercial pedestrian street, and then looking at the full space inside the ring, including nearly 2000 yuan crystals and nearly 100 animal cores of mutated wild monkeys, Zhang Mu is completely confident about tonight's transaction.

"Era merchants in Xi'an city? I'd like to see if you are excited about this performance."

Who knows, in a far corner, a figure hiding deeply witnessed the whole process of Zhang Mu cleaning up the zombies and Liu Shuo's body being thrown out, and fled the scene trembling.

In a humble Hotel, a group of people were sitting in the middle of the hall, surrounded by smoke.

It was Lin Shui's gang just now. The big man who was close to Lin Shui stepped on the ground and said anxiously, "cousin, let the mouse follow the skinny monkey for an hour and a half. Why don't you come back?"

It turned out that he was Lin Shui's cousin, but their personalities were completely opposite.

Lin Shui ignored him, half leaned on the sofa and continued smoking.

Suddenly, Lin Shui's head buried in his brown hair was raised and suddenly moved towards the door. Everyone else was nervous by Lin Shui's behavior and pointed weapons at the door of the hotel.

It was the little man who peeped at Zhang Mu's party just now. He stumbled to Lin Shui. It seemed that he ran too fast. He slipped and fell to the ground. He kept talking.

"All dead, all dead."

Just now the big man asked aloud, "what's the matter, mouse? What's the matter with you? Make it look like this?"

The little man called mouse still said vaguely that he was all dead. He was no longer conscious and didn't notice the big man asking him.

Lin Shui's cousin was angry. He slapped the mouse in the face and shouted angrily, "what are you doing with me? Tell me clearly!"

The pain of this slap woke the mouse up. He covered his hot face, looked at the forest water staring at him, swallowed his saliva, and replied with a sad face, "lingo, thousands of zombies in the downtown commercial pedestrian street were killed by the man just now. There is no one left. Even the madman who specially cut off his head was killed and became a mummy!"

All the people present just listened to the mouse's words, imagined the tragedy of the battlefield, and immediately took a breath with one voice.

Thousands of zombies in the city center were solved by the man just now in an hour and a half?

And the madman who appeared like a ghost, specialized in hunting and killing people with the same evolutionary ability as himself, and had the habit of collecting heads, was turned into a mummy by that man?

Now, even if you are as calm as forest water, you can't sit still at this time,
