As a reptilian creature, the mutant gray crocodile is different from ordinary crocodiles, it can dive for a long time without going ashore, and it can also go into the water for days or even months, which is one of the very successful cases of mutation.

However, the mutant gray crocodile is huge, and the speed of land combat is too slow, and at this stage, in the case of land combat, the mutant gray crocodile does not play much role.

Su Chen thought about it for a long time, and planned to take it with him first, and after it devoured enough fourth-level mutant creatures and successfully transformed into a fifth-level mutant creature, he would release it into the sea in the north of Nanshi, and then come back to help when it could fight on land without hindrance.

For Su Chen's decision, the mutant gray crocodile naturally agreed, its thoughts were almost the same as Xiaobai's, as long as there was food, there was no refusal.

Su Chen found a medium-sized truck with a full fuel gauge near the small pond, and after throwing the ash into the container, Su Chen didn't look at the road map, just drove all the way north.

About ten days ago, Su Chen was wandering around Nanshi, and it was difficult to see the shadow of the fourth-level mutant creatures, and it was only less than ten days later, and the number of fourth-level mutant creatures had increased significantly, and Su Chen suspected that in other unknown regions, fifth-level mutant creatures might have sprung up like mushrooms after a rain.

Su Chen has gone all the way this time, and the number of third-level mutant creatures on the road is already comparable to the number of second-level mutant creatures ten days ago.

Mutant creatures quickly mutate by devouring mutated creatures of the same type or other siblings.

It stands to reason that the overall number of mutated organisms should be greatly reduced if such a number of third-level or even fourth-level mutant organisms appears, but the actual situation is that the overall number of mutated organisms is not decreasing, but showing an upward trend.

It is worth mentioning that as far as Su Chen currently knows, the first to fourth level mutant creatures, no matter what variety of mutated creatures, will not have the ability to reproduce, which means that their number will only get smaller and smaller, and it is impossible to increase.

Nowadays, the mutant creatures in Nanshi have not decreased with the tide of time, but have gathered more and more, Su Chen doesn't know what kind of charm Nanshi has, attracting more and more mutated creatures to gather here.

There are tens of thousands of types of mutated creatures, and the number is even more than hundreds of millions, if it is easy to deal with human beings who turn into zombies, the key is that all creatures on this planet have the possibility of mutation.

Su Chen didn't want to be a savior, but as a survivor, he had some sense of rebellion and thoughts in his heart about mutated creatures dominating the planet.

This is Su Chen's first time driving a medium truck, after reading the relevant instructions and the assistance of a variety of specialists, Su Chen was soon able to drive the medium truck proficiently, compared to the Z3 off-road he originally drove, he felt that the performance of the medium truck was simply terrible.

Su Chen drove north for half an hour, encountering many mutant creatures along the way, but there was no shadow of a fourth-level mutant creature.

Su Chen didn't know if there was a problem with his route, and drove all the way to the north, even if there was no shadow of a fourth-level mutant creature, even the third-level mutant creature rarely sensed it.

Although the number of third-level and fourth-level mutant creatures is small, the total number of mutated creatures is still very high, and Su Chen even wonders if this area will be the same as the urban area of Nanshi, where there will be multiple fourth-level mutant creatures fighting.

In order not to be in the cargo box behind the car with Big Ash, Little White Nest is curled up in the passenger seat, although it looks like a stupid husky, but it is essentially a cat.

Regarding Su Chen's question, Xiaobai agreed, and the big ash in the back box quickly agreed.

After getting the unanimous approval of Xiaobai and Da Ash, Su Chen's suspicion was recognized by him as true.

He decisively stepped on the brakes and ordered Xiaobai and Big Ash to act and find out the fourth-level mutant creatures in this area.

Xiaobai had long been fed up with the crowding in the passenger seat, and in front of Su Chen, he kicked the door next to the passenger seat and jumped down.

Hearing the movement, Da Ash wanted to continue to sleep in the cargo box, but seeing that Xiaobai took the first step, he had to violently break open the door of the cargo box with steel claws, and fell off the car with his tail.

Although the big gray is amphibious in the waterway, it can't be called an amphibian in the true sense, it was a real reptile before the mutation, but in Su Chen's eyes, it is an amphibian.

Su Chen quickly arranged the route and scope for Xiao Bai and Da Ash.

Xiaobai walked to the west side, because it was fast and Xiaobai could probe the situation, so its advance range was twice as high as that of Da Gray.

The big gray walked to the east side, its skin was hard, although it would not cause fatal trouble, but its speed was really unbearable to look at, and Su Chen had to reduce the range of its search route.

As for Su Chen, he kicked the car door and continued to move towards the north side.

Once one of the three parties finds the target, they will alert each other, and the other two parties will immediately rush over.

Because the consciousness of Xiaobai and Da Ash is connected to Su Chen, Su Chen's consciousness world is like a transit station, even if Xiao Bai and Da Ash's consciousness are not in Su Chen's consciousness world, because Su Chen's consciousness world channel is not closed, they can still be connected with each other.

After the route separated, Su Chen didn't speed up, and his perception and detection of fourth-level mutant creatures were far weaker than Xiao Bai and Big Gray.

If he is moving at full speed, not only will it be easy to miss the target, but he will also increase the time to support the other two lanes.

The strength of the little white monomer is very strong, and in the face of the joint efforts of two fourth-level mutant creatures, it can barely resist, while the big gray skin has a strong defense, even if three or five fourth-level mutant creatures join forces together, it will not be able to break the defense in a short time.

Su Chen wasn't worried that something would go wrong with them, but he was afraid that things would go differently than he expected, so he couldn't run far.

Once they reach the designated position and do not find the target, they will retreat to the next gathering place, and Su Chen will redraw the route and reconnoiter again.

In this way, there is no slowness in support, it just takes a little more time.

Su Chen, who has experienced so much, knows the importance of time, and also knows that everything cannot be in a hurry, he believes that as long as there are fourth-level mutant creatures nearby, this kind of operation is definitely the most stable.

Xiao Bai and Da Ash unconditionally carried out Su Chen's order, and after arriving at the designated place, they quickly came to the next meeting place, and then continued to set off.

The northern suburbs of Nanshi are vast, and Su Chen is not sure when he will find his goal, but he believes that his current efforts are definitely not useless.

After a few trips, the evening sun exuded residual heat, Su Chen, Xiaobai, and Da Gray came to the gathering point again.

Su Chen analyzed it for a while and gave the route for this time, which was also the last trip today.

Xiaobai, who didn't eat, was slightly disappointed, and Da Gray looked lazy, eager to sleep on the ground now.

After deciding on the route, the three quickly separated for the last expedition of the day.

Five minutes later, Su Chen, who was heading all the way north, suddenly stopped, and in his perception, several flickering figures appeared.

Because the target was on the outermost part of Su Chen's perception, he couldn't clearly sense the movements and combat power of these figures.

However, the mutated creatures that could be perceived by Su Chen were naturally not ordinary goods, he didn't think much about it, and after determining the general direction, he accelerated his speed.

Su Chen hid his aura all the way, even if he sped up, it would be difficult for the fourth-level mutant creatures to detect him.

In just half a minute, Su Chen's perception could clearly sense four energy fluctuations, and without analysis, Su Chen immediately confirmed that there were four fourth-level mutant creatures here.

Su Chen didn't know the purpose of their gathering here, and he didn't need to know, he just wanted the final result.

Before Su Chen could inform Xiaobai and Da Ash of the situation here, Da Ash first came with the news.

Big Ash rushed ahead of Su Chen, and also found the fourth-level mutant creature, because it was not very sure, it chose to get closer to check, but it didn't expect to attract the attention of the other party, and after passing the information, it had already fought with another fourth-level mutant creature.

Xiao Bai didn't find the target, it quickly received Su Chen's order, quickly turned to Su Chen's direction, and came to support Su Chen.

And there is only one opponent of Big Ash, so he will be contained by it for the time being, waiting for Su Chen and Xiaobai to solve the trouble here, and then go to support.

Confirming that Xiao Bai was already on his way, Su Chen continued to move forward, and the shadows of the four mutated creatures soon appeared in his sight.

Their actions exceeded Su Chen's expectations, one by one, they were in place, communicating in a language that Su Chen didn't understand, and it looked like a gathering of friends.

Su Chen once suspected that they hadn't left here because another "little friend" from the party had been stopped by Big Ash.

Not being able to understand each other's language was a rather distressing thing, but fortunately, Su Chen was not interested in what they were communicating.

In just a minute, Su Chen could see that these four mutated creatures had obvious movements, Xiao Bai's arrival was obviously noticed by them, and they should be discussing countermeasures against the enemy.

The strength of these four mutant creatures is average, once Xiaobai and Su Chen join forces, in the case of two against four, Su Chen thinks that his victory rate is very high.

Su Chen had already had a very detailed analysis of their combat power.

Fourth-level speed zombie, because its arm is no different from a normal person, Su Chen changed its name to a speed zombie.

There are also fourth-level power-type zombies, fourth-level mutant evil dogs, and fourth-level mutant giant tortoises.

The names of the Mutant Dog and the Mutant Giant Tortoise are provided by the Zombie Illustrated Book.

The Mutant Dog has an advantage in speed, and it has no other skills other than beast transformation.

As for the mutant giant tortoise, it is made of sea turtles, the size is comparable to a large suitcase, its mutation is very successful, and its speed on land is faster than that in the sea, and it can reach 500.

Needless to say, its defense, normal defense is slightly worse than Big Ash, but it doesn't have a beast skill, but it has a hard shell skill.

As the name suggests, this is a defense-type enhancement skill, and the effect is to strengthen 100% defense, which means that its turtle shell hardness can't even be pierced by bullets.

However, Big Gray is very good in terms of strength and agility, while the Mutant Giant Tortoise only has defensive advantages, and its strength, speed, and agility are all weak and can't bear to look at it directly.

Su Chen had wondered why the mutant giant tortoise was here, but until now, he hadn't found an answer.
