After the blizzard stopped, the temperature held steady at around minus sixty degrees.

Big Camphor Tree Base.

The group raised their crossbows and shot for quite a while, with more and more zombies and corpses piling up under the tree, gradually increasing in height.

The appearance of the zombie hill brought a great shock to everyone.

They had never thought they could use the zombies in this way to deal with them.

But the premise for this was that they had to be in a relatively safe location to do it so recklessly.

The temperature was very low, and after 30 minutes on the wall, the group began to feel extremely cold.

Even though they were all wearing thick clothes, they couldn't withstand the fact that the outdoor temperature was way too low.

At this moment, the zombie hill outside the wall, after piling up to a relatively high level, suddenly collapsed, countless zombies rolling down.

Many of the deceased zombies still had arrows shot by Li Yu and his team inserted into their heads.

"Second Uncle, why don't you go warm up in the duty room first?" Seeing Second Uncle's body tremble slightly, witnessing his spasming shoulders, Li Yu knew his muscles were contracting.

Indeed, most of them were originally long-term residents of the Southern region, accustomed from a young age to temperatures of twenty to thirty degrees, making this extreme cold very hard for them to adapt to.

Second Uncle heard Li Yu and didn't pretend to be tough, nodding his head and walking into the duty room.

"Bai Jie, Shang Xue'er, Ma Di, Haoran... you all should go inside too, don't end up freezing something serious." After seeing Second Uncle leave, Li Yu said to the others.

Bai Jie and the others didn't refuse; in fact, they were already barely holding on.

Thus, they followed Second Uncle into the duty room.

Even while wearing leather gloves and thermal clothing, breathing cold air, the pervasive cold air seeped through every gap of their bodies, lowering their body temperatures.

They stopped shooting, not just because they were tired from constant shooting, but also because the cold affected their aim, making it difficult to hit the zombies' heads now.

Li Yu felt alright, perhaps due to his training, or maybe because of his rebirth, his physical condition seemed much better.

Slowly, Li Tie and Dapao also couldn't hold out, and after notifying Li Yu, went into the duty room to warm up temporarily.

Generally, when they went out to patrol from the duty room, it never exceeded 15 minutes; like just now, Li Tie and the others stood on the wall, lasting over 40 minutes.

After Li Tie and the others left, Li Yu felt somewhat cold too, but far from unendurable.

On the entire front wall, only Third Uncle and Li Yu were left.

Third Uncle remained calm, suddenly pointing to a place on the right side of the woods, saying to Li Yu, "Xiao Yu, is that a roe deer?"

Li Yu focused, looking in the direction Third Uncle pointed, and sure enough, there was a roe deer, though this roe deer was also infected by the zombie virus, its body shape not changing much, but its skin color from original yellow turned to yellow and white patches.

It looked like a skin disease, somewhat unsightly.

Roe deers' jumping ability was originally quite high; normal roe deers could jump over two meters.

That roe deer bounded among the zombie group, with a few jumps leaping to the place where the zombie bodies were.

The originally lengthy teeth, after being infected by the zombie virus, became longer and sharper.

Opening its mouth, a row of densely packed sharp teeth tore into the zombie corpses.

Li Yu and Third Uncle exchanged a glance as they witnessed this scene, inexplicably finding it eerie.

Before the Doomsday, people often used roe deer teeth or antlers as decorations on keychains.

But seeing these roe deers turned into zombie roe deers now, they felt somewhat unsettling.

The zombie hill that just collapsed was now in chaos.

Those zombies frantically fought over the corpses of their kind to gnaw on.

Over time, the zombie bodies were visibly consumed to nothing.

Zombies flooding over from the distance didn't reduce but instead increased.

Zombies outside the wall also began focusing on the wall here, while the roe deer within the zombie crowd jumped several times, arriving at the Big Camphor Tree Base wall.

Third Uncle noticed this roe deer's jumping ability, stronger than before infection.

One jump almost reached three and a half meters high, three or four meters far.

Knowing that normal roe deer jumping ability was just over two meters, this amounted to a fifty percent increase.

Woosh—

The roe deer kicked off its hind legs, leaping towards the wall.

Standing on the twenty-meter-high wall, Li Yu was entirely unperturbed, but closely watched the roe deer.

Third Uncle raised his crossbow slightly, ready to immediately kill it if it jumped higher.

Bang—

The roe deer's head directly hit the hard wall with tremendous impact.

This collision sounded clear even to Li Yu and Third Uncle higher up on the wall.

The icy surface on the wall was shattered by the impact.

Yet when the roe deer's antlers struck the exceptionally hard reinforced concrete, it was unable to budge it.

With a crisp snap, the roe deer's antlers broke.

Soon, the roe deer slowly tumbled down.

Falling on several zombies below the wall.

After falling, the roe deer didn't die but instead scrambled shakily back to its feet.
