"Xiao Zi, let's go!"

Liu Wen didn't give Yu Li a chance to speak again, but directly commanded Xiao Zi in the air, and flew directly towards the dense sky above the mutant rat group.

Liu Wen, on the other hand, has been following Xiao Zi's side, waiting until Xiao Zi flew over the city wall of Baihua Base City.

Liu Wen began to input the plant ability energy in his body to Xiao Zi.

At the same time, Liu Wen also had time to check the battlefield at this time.

Originally, most of the trenches dug out by the White Birch Base City outside the city walls to deal with zombies had been filled with the corpses of mutant rats.

And outside the city walls of White Birch Base City, there are also a large number of mutant rat corpses, piled up.

Many mutant rats stepped on the corpses of their companions and climbed the walls of the base of White Birch City.

Before the end of the world, rats could easily climb up uneven walls.

Now in the last days, the rat has become a mutant rat, and the ability to climb has not degraded, but has strengthened a lot.

And the city wall of Shirakaba Base City, when it was built, in order to ensure the progress, a large number of laymen were used.

In this way, the surface of the city wall of the White Birch Base City is not smooth, and it is not too difficult for these mutant rats to climb up the wall.

It's not good, but there are countless fortifiers on the city wall, and they all use spears and other long weapons now.

As soon as the mutant rat climbs up, they use their spears to stab it down.

Whenever a mutant rat is pushed down by the reinforcers on the city wall, a height of tens of meters, if it falls, it is basically certain death, not to mention, most of these mutant rats that fall down have been poked a few holes in their bodies by spears.

And the mutant rats under the city wall are not only desperately climbing the city wall, but also many are constantly devouring the corpses and beast crystals of their companions.

The mutant rat's behavior of devouring the corpses of their companions made the people on the city wall of the base breathe a sigh of relief, so that because there were too many mutant rat corpses under the city wall, they would not be piled up directly when the time came, so that the mutant rats would go up to the city wall as if they were walking on the ground.

But in the same way, the mutant rats devouring the corpses of their companions like this, mainly after devouring the beast crystal, their combat effectiveness will be significantly improved.

Under Liu Wen's command, Xiao Zi did not get entangled near the city wall, but flew directly to the center of the city wall and the dam, and then at a position more than twenty meters above the ground, he began to attack the mutant rat swarm back and forth.

Ordinary mutant rats can't attack Xiao Zi who is more than twenty meters in the sky at all.

But Xiao Zi can easily roll up a mutant rat every time she stretches out a vine.

When the mutant rat that was rolled up by Xiao Zi returned to the ground, it had already turned into a dried corpse, and the crystal nucleus in its head had disappeared.

At this time, Xiao Zi, with the support of Liu Wen's plant ability, the number of vines that split out had exceeded 10,000.

In fact, if Xiao Zi bursts out with all her strength, she can even split more vines.

However, Liu Wen's plant ability energy supply was too stressful.

The more vines Xiao Zi splits, the faster Liu Wen's plant ability will naturally be consumed, and the energy is conserved, as if how much money is taken and how much work is done.

Today's Liu Wen has three hundred second-level magic fruits in his hands, basically, taking one can almost replenish the energy he consumed, and if it is a pure war of attrition, Liu Wen is really not afraid.

What worries Liu Wen a little is the zombie army.

"Twitter..."

Half an hour after Liu Wen and Xiao Zi joined the battlefield, hundreds of Wang Pin's mutant rats in the mutant rat group let out a rapid cry again, and then took the lead and rushed towards the city wall.

"Xiao Zi, attack!"

"Nana, be careful!"

Liu Wen's eyes were sharp, and he could clearly see that these Wang Pin mutant rats that rushed over were different from most of the previous Wang Pin level 4, and the vast majority of these mutant rats were Wang Pin level 5.

The current Liu Wen may not care about the third-level and fourth-level mutant beasts of Wang Pin, but he is very short of those of Wang Pin level 5.

Not to mention anything else, if Milk Bean wants to be promoted to level seven, it needs a hundred level five Wang Jing, and Kitty Eagle is still level five now.

The wings of Liu Wen and the three of them also need a large number of fifth-level Wang Jing to improve their level.

Among these hundreds of king-grade mutant rats, there are at least a hundred or so king-grade fifth-level mutant rat kings.

Obviously, this batch of rat kings should be the highest-ranking kings in this group of mutant rats.

As for why these king-grade mutant rat kings rushed towards the city wall of the base city so desperately, it was mainly because of the arrival of the zombie army.

From the very beginning, the mutant rat colony went berserk because it was cut off by the zombie army.

These mutant rats were also dead-eyed, and they were cut off by the zombie army, and began to storm the walls of the base city.

It's just that the city walls of the base city are obviously not so easy to capture, and the group of mutant rats of less than 10 million has directly lost the vast majority of them in the crazy attack of about half an hour, and in the entire battlefield, the number of mutant rats is still one or two million.

The city wall and under the city wall were already rivers of blood, and the entire land was dyed red by the blood of the mutant rats, and after the blood of the mutant rats dried up, both the city walls and the ground showed a dark red color.

Fortunately, now that the weather is getting colder, there is no epidemic.

Whoa...

Xiao Zi fought against hundreds of Wang Pin mutant rats, and its flight altitude suddenly rose to more than 100 meters.

If Xiao Zi's flight altitude is still more than twenty meters, Wang Pin mutant rats are not ordinary mutant rats, they can easily attack Xiao Zi.

Even if Xiao Zi flies to a height of 100 meters now, it is not too difficult for these level 4 and 5 mutant rat kings of the king product to attack Xiao Zi.

Because he was fighting against a large number of king-grade mutant rats, Liu Wen did not limit the number of vines in Xiaozi at this time.

In just an instant, the number of vines split out by Xiao Zi doubled again.

Xiao Zi itself uses wings to support flight, and the wingspan is now more than a kilometer.

More than 20,000 vines, fluttering in the wind, for a time, attracted all the attention.

Woohoo!

Whoa...

Driven by the huge wings, Xiao Zi quickly came to the top of this group of king-grade mutant rat kings, and then countless vines began to entangle these king-grade mutant rat kings in batches.

"Twitter!"

"Twitter..."

Wang Pin Mutant Rat King, when faced with so many vines entangled in Xiao Zi, most of them were afraid and wanted to escape.

These rat kings can evolve to the fourth or fifth level of Wang Pin, and their IQ has already improved a lot.

From Liu Wen's milk bean and Xiaoying, it can be seen from the execution of his orders that as these mutant beasts increase in level, their intelligence will gradually improve.

And the biggest weakness of intelligent creatures is that they are afraid of death, and when their lives are in crisis, ordinary intelligent creatures will choose to run away!

The third is offered!
