The two walked and chatted, all the way was like a leisurely stroll, similar to the two of them wandering around before the end of the world, and after walking for more than an hour, there was not a single creature that could make Yang Fei look back, which made Li Shura really envious.

"I really can't compare with you..."Li Shura sighed with emotion: "What about the rest of your Great Ideal Group? Are they all the same as you? ”

Yang Fei thought for a while and said, "Although Duo'er's grade is very small, if you really fight her, I guess it will be to see if you can sneak attack her at close range when she is defenseless... After all, the flying sword is a bit overbearing. ”

Li Shura nodded, but it was like this, he had seen it thousands of times along the way.

"Jiang Shiyu's words, um... How can I say it, if I have a flying sword, I don't dare to say that I can beat her, after all, she is a crazy woman..."

Li Shura nodded again. Yang Fei continued: "If you are a big cat, you two should not have to fight, the big cat's combat ability is not strong, but it has mind control, although it can't control you, but it can definitely make you helpless..."

"But if it's Liu Yang, your combat strength should be about the same..."

"Is that the guy younger than me?"

…

The two chatted all the way, approaching the location of the city center, and Li Shura finally had a chance to make a move, and when they arrived here, low-level zombies rarely appeared, and more high-level zombie creatures appeared.

Yang Fei fought with a third-order mutant beast, and the flying sword passed through the opponent's head, but did not kill the opponent. The life core of the third-order mutant beast was no longer in its original brain position, but in the condensed evolution crystal position, Yang Fei used his flying sword to shuttle back and forth in the opponent's body, hoping to shatter the opponent's evolution crystal. At the same time, he is constantly running back and forth, dodging the attacks of the other party.

Li Shura began to pick up his iron rod and smashed it at several other creepers, he jumped seven or eight meters high, directly crushed the creeper's head, and at the same time jumped on the other party's body, dodging the bite of the other creeper, and turned around with a stick again.

Although his iron rod is only more than a meter long, compared to these crawlers who are more than ten meters at every turn, it looks very lethal, but in his internal strength Cui Dongxia, this iron rod gave birth to a long period of something like fighting energy, and it was also like a knife, and the iron rod flew up and down in his hand, and five or six second-order creepers were smashed by him one by one in just a few minutes.

When he had time to look at the battle situation on Yang Fei's side, he found that Yang Fei had been watching him for a long time, and he couldn't help but smile slightly, sighing that his competitiveness was still so strong, and he began to dig the evolution crystal of the creeper.

Yang Fei unleashed his flying sword and flashed over the corpses of several other creepers, helping Li Shura pack up the loot.

"Give." Yang Fei handed over the third-order evolution crystal just now to him as well.

"Don't you need this?"

"I have a lot..."Yang Fei spread his hand and said, Li Shura was almost choked to death, although he could easily kill the second-order mutant beast, but he rarely had the opportunity to kill it, because the current second-order and third-order mutant beasts were mostly in the city, if a third-order or fourth-order creature was introduced, he would probably be planted there.

Li Shura looked at the fallen third-order mutant beast and said with emotion: "Originally, I was still a little worried, but now it seems that even if there are your so-called fourth-order mutant beasts in this city, most of them are not your opponents..."

Yang Fei shook his head when he heard this, and said, "It's hard to say, it's hard to say, there was a time when I thought so..."

That huge beautiful zombie, at the beginning, everyone in the Great Ideal Group didn't take it seriously, and they were still joking with each other, but when they really fought, they were almost killed by a brick...

Who can bear the fact that TM and that mobile building are photographed?! Yang Fei's face is not very good-looking when he thinks about it now.

"Don't underestimate the mutant beasts of the third order and after the third order, the mutant beasts of the second order have a fixed form, many of the second-order mutant beasts are the same, but the third order is not good, the third-order mutant beasts are almost not the same, and the weaknesses are not the same... It's kind of out of its own evolutionary path..."

Yang Fei popularized the level of mutant beasts defined by his own team to Li Shura, needless to say, the first-level ones are creatures that have just been infected with the zombie virus, and the most common ones in the second order are crawlers and the like, large mutant beasts evolved from zombie dogs, and the second-order humanoid evolved from zombies also exists, but not much, because humans are difficult to fight for beasts in terms of physique, the reason why there are many creepers is that there is enough food, and they are also infected with the virus, zombie dogs and humans have a lot of food, but humans have a lot of food because of instinct and physiqueIt's hard to beat the zombie dogs.

The third-order mutant beast is a mutant beast that has walked out of its own unique evolutionary path, and with a little wisdom, it knows how to hide its own life origin, that is, the evolution crystal. Fourth-order mutant beasts are a step further, because they have taken another step on their own evolutionary path, so the consumption of biological energy has also increased significantly, and this kind of creature is usually in a sleeping state, in order to reduce the consumption of biological energy.

As for the fifth order, they don't have an accurate definition yet, but a few mutant beasts that can't be described as the fourth order are temporarily considered to be the fifth order, such as the tentacle monster in the Sea of Japan, such as the one in the Bering Strait...

Li Shura listened to it with relish, this statement is very interesting and reasonable, and there are some benefits to understanding this. At the same time, he also admired the Great Ideal Group, and he had fought with so many zombie creatures, which was really well-informed.

The two were chatting happily. A signal suddenly appeared on the side of the city, Yang Fei looked up, a signal flare flashed in the sky, he pulled up Li Shura and flew over with his sword, and many zombie birds attacked in the air, but they were all killed by the two of them one by one.

In just a minute, the two of them came to the place where they asked for help, and in this direction was Liu Yang's big cat, and they were being chased by a strange-looking guy.

"Earth Dragon? Lizard? Is there anything else in the city? Yang Fei muttered to himself with a strange expression.

He glided on the ground, put Li Shura in the position of Liu Yang and the big cat, and stepped forward to block the strange creature himself.

The creature was pitch black, had limbs, two white bones on its back, and a head that looked a bit like a lizard, half-erect, and a mouth full of sharp teeth that made people's hearts see.

"Be careful! This guy's skin is very hard, and the saber that I instilled with internal strength is also difficult to cut through the skin on the other party! Liu Yang shouted, it seems that before asking for help, he and the big cat had already fought with this creature, but they found that it was not low.

"Don't worry!" Yang Fei made a gesture with a few people, asking everyone to hide first, this creature doesn't seem to be able to fly, so he is not in a hurry, observe it first, and find out the weakness of the other party.

Not long after, Duo'er and Jiang Shiyu also arrived, and they also saw the signal for help.
