Oliver takes a glance at his watch. Only one minute has passed. This wasteland isn't big, and with over two hundred zombies crammed together, his moving space is shrinking constantly, and the chance of escaping is getting slimmer and slimmer.
Facing these tireless zombies, Oliver feels helpless. If he had an automatic rifle and enough bullets, he could take them out in ten minutes.
But he doesn't.
Oliver looks at the weed - covered wasteland and gets an idea. He approaches the mud wall which is more than ten meters high. With the help of a steel pipe, he starts climbing. When he's halfway up, he digs out a place where he can stand and sits there, swinging his legs and mocking the zombies, "Aren't you guys so tough? Come on up!"
By now, three minutes have passed. James have filled up the gasoline. Oliver just needs to hold off for a few more minutes to let him get away safely.
The zombies swarm to the bottom of the mud wall and start climbing with their hands. In less than a minute, several of them have climbed nearly three meters high. They stick their fingers into the soil, not caring about the rotting flesh falling off.
More and more zombies are climbing up. Oliver's face changes. He didn't expect they could actually climb up.
"Well, if that's the case, don't blame me for being ruthless." Oliver grips the steel pipe tightly. When the zombies get close, he hit them away.
Just when Oliver is in a flurry, a male gas - station - attendant zombie in the zombie horde stops moving. Its rotting flesh and bones change from pitch - black to blood - red. Muscles bulge one by one, bursting its already tattered uniform. Its whole body trembles, and it lets out a howl like a ghost.
Oliver is stunned when he sees this. "Fuck! What's going on here?" The muscles of zombies were supposed to be destroyed by the virus, but now new muscles are growing. This situation completely shatters his understanding of the XR virus.
Just then, Isabella shows up and warns, "This zombie has mutated. Its ability is about five times stronger. You ran into this one - in - ten - thousand chance of mutation."

Oliver comes to his senses. Thinking about the terrifying ability of the mutated zombie, he breaks out in a cold sweat. "Zombies can mutate? If this keeps up, will there be any living space for humans after a few mutations?"
Isabella explains that the mutation rate of ordinary zombies is one in ten thousand, but certain conditions are required. Approximately, one or two mutated zombies may appear among every fifty thousand zombies. The probability of further evolution after each mutation is also one in ten thousand.
Theoretically, among the seven billion zombies in the world, about three hundred and fifty thousand mutated zombies will be produced, and among them, about one hundred and fifty will be three - time evolved zombies. The principle of the XR virus is very complicated, so the appearance of four - to - five - time evolved zombies can't be ruled out. The evolved and mutated zombies are classified into levels R1 - R5, and there might even be an R6 level.
After hearing this, Oliver feels a bitter taste in his mouth. The ability of an R1 zombie is about three times that of a human, and an R2 zombie is seven times. With his ten - times - human - strength ability, he can barely deal with an R2 zombie.
During their conversation, the male gas - station - attendant zombie finishes evolving and reaches the R2 level. Its throat can make monotonous notes. It first growls at Oliver, then leaps from the zombie horde, lunges onto the mud wall, and crawls towards Oliver quickly, using both hands and feet.
Oliver's scalp tingles. This speed is several times faster than that of an ordinary zombie. It's going to be hard to deal with.
The R2 zombie comes at him fiercely. Oliver pulls out the steel pipe and stabs at its head. The R2 zombie turns its head to avoid the attack, but its body still rushes towards Oliver. Its cyan - colored fingers are extremely sharp and incredibly hard.
Oliver didn't expect the R2 zombie to be able to dodge the attack. It seems that it's not just about enhancing muscle strength. He adjusts the direction of the steel pipe slightly and stabs it into the R2 zombie's eye, destroying its nerves.
With this fatal blow, the R2 zombie twitches once and then stops moving.
Oliver throws away the corpse. This seemingly simple strike has exhausted his strength. If he hadn't hit it, he would have been very difficult for him to escape in such a narrow space.
Thinking about the speed of the R2 zombie, if it were to appear in front of ordinary people, even with powerful firepower, it would be hard to hit. And they'd have to hit its head to kill it.
If there were a few R2 zombies hidden among a group of zombies, it would be a devastating disaster for teams that don't know about them.
At this moment, Oliver finally sees James running at full speed with the gas can. He stabs the climbing zombies down and continues climbing up the mud wall. Above the mud wall is a hillside. After getting rid of the zombies, he rushes towards the minibus. He has to get through this section of the road before the zombies swarm back to the gas station.
