"Chief, according to the monitoring of our weather satellites, this cold air will arrive near us around 11 o'clock tonight as scheduled. At that time, the temperature here will plummet by about 10 degrees Celsius in two hours, reaching a low temperature of minus 17 degrees. ”

When the zombies outside the castle were actively preparing for this fifth attack on the Steel Castle, in the command room of the Steel Castle, a meteorological expert was reporting the new meteorological situation to Chen Yuan.

Chen Yuan, who heard the report, immediately breathed a sigh of relief.

In fact, this cold air had been monitored by the Meteorological Department of the Iron Castle 10 days ago.

Chen Yuan has also been waiting for this day.

Don't look at it as a 10-degree drop, but it's already very powerful.

At that time, due to the impact of low temperature, the mobility of zombies will be further limited, and the defense of the human alliance will naturally be easier.

In fact, even if the temperature only drops by one degree, Chen Yuan will be very happy.

Because any drop in the strength of zombies means that the human alliance can sacrifice a few or even dozens of fewer people!

Even at this time, the population under the leadership of the Iron Castle is as high as 400,000, and Chen Yuan still values every life!

What's more, now that the temperature is to be lowered so much at once, the decline in the overall strength of the zombies is definitely more than a little simple.

Wang Luzhou also said happily: "This cold air is really timely, so that tonight's battle will be much easier." ”

At this time, Qin Cheng was standing by the window, holding a night vision binoculars and looking at the zombie position opposite. The zombies on the opposite side are now actively deploying troops, and it is estimated that it will not be long before they start attacking.

Hearing Wang Luzhou's words, he jokingly said: "I think God is really partial sometimes, and he has always been very good to Chen Yuan." Look at this cold air, it doesn't come early, it doesn't come late. Just come when the zombies are about to attack, this is to put the zombies in a dilemma! This kind of luck sometimes even I have to envy. ”

Chen Yuan smiled: "God is a human being who favors our Iron Castle. ”

Then, Chen Yuan reminded Liu Jinlong: "Old Liu, it is beneficial for us that the cold air can arrive as scheduled. However, the coalition forces also need to be prepared in this regard. Inform every soldier and let them remember to keep warm, so that when the zombies are not frozen, our own soldiers will be frozen. ”

Liu Jinlong also nodded with a smile and said, "It has been notified, and every soldier has a warm-up patch." Just wait for the temperature to cool down tonight and give the zombies a head-on blow. ”

*************

The zombie attack soon began, and the 1.2 million zombies were still charging all over the mountains and fields.

As for the Steel Fort, the tank brigade still launched an attack on the zombies' positions 1 hour after the zombie attack began.

It's just that this time the zombies seem to be well prepared.

The Corpse King was 20 kilometers behind the position, scattering a large number of zombie scouts.

As soon as the two tank brigades of the Self-Salvation Army appeared, the Corpse King immediately found out.

Although at this time, it only left 200,000 zombies on the position, as long as it was transferred in advance, 200,000 zombies could not be moved by the two tank brigades of the Self-Rescue Army.

Therefore, after the tank troops arrived near the zombie position, in the face of the zombie army that had been prepared and waited for a long time, they could only put a few cannons from afar, and quickly turned around and retreated.

The harassment scheme came to naught. In fact, this is also within Chen Yuan's expectations.

But fortunately, at this time, the expected cold air finally arrived, and the gradually decreasing temperature made the speed of the attacking zombies begin to slow down gradually. It's like athletes entering the second half of a 10-kilometer race, and their physical strength has dropped.

This is a good opportunity for humanity.

The warriors have exerted their strength, and the loss of zombies has gradually begun to increase.

At first, the Corpse King didn't really care too much.

After all, it seems that the temperature drops at night, which is normal.

But slowly, it found that the temperature dropped a little unusually tonight.

Because the temperature has continued to drop rapidly after dropping to the lowest temperature of last night.

The mobility of the zombies under his command has also been further affected.

By 12 p.m., the temperature had dropped to minus 13 degrees.

Many zombies have a lot of ice on their bodies, which not only increases their weight, but more importantly, the activities of various troops in their bodies begin to become very inflexible.

From the beginning of the attack, it was only two hours, and 200,000 zombies were gone!

And until now, the zombies have just attacked the human wall.

This suddenly made the Corpse King a little uncertain.

Is it to continue the attack? Or do you retreat and wait for the temperature to rise a little during the day before attacking?

Continuing the attack, the temperature seems to be continuing to drop at this time. Obviously has a great influence on its zombie army. At that time, the rate of casualties will be further increased.

And retreat, and wait for daylight to attack.

Daytime attacks also have the benefit of daytime attacks, with their zombie archers and Molotov cocktail-throwing zombies seeing better and hitting more accurately than at night.

And at this time, near the Iron Castle, the temperature during the day, especially at noon, can still be above freezing. As zombies, as long as the temperature is not lower than zero, their mobility will not be affected. At least twice as fast as the current one!

But now retreat, the previous 200,000 won't be in vain!

The walls of the human race have finally been stormed, and their harassing forces have been repulsed. The Corpse King is a little unwilling to give up, what if the temperature doesn't continue to drop too much?

With such a fluke mentality, the corpse king hesitated and hesitated, and the time was delayed for more than ten minutes.

By this time, the temperature had dropped to minus 15 degrees Celsius and was still falling.

Zombies are further affected, with more zombies being shot every second than before.

And more importantly, the territory of zombies on the city wall has not only not increased compared to before, but has gradually shrunk a little, and they have a tendency to be driven off the city wall by the human defenders.

This suddenly made the Corpse King secretly annoyed, and at the same time, he finally made up his mind.

At this time, on the wall of the Steel Castle, Chen Yuan hurriedly said to Liu Jinlong: "Old Liu! Tell the troops to put some water in it! Don't fight too hard! The zombies are going to be driven off the city wall by you! You're going to scare the zombies away! ”

But it was already too late.

As soon as Chen Yuan's words were finished, the zombie army was already under the control of the Corpse King, and Hula began to retreat.

They charge fast and retreat faster.

The human coalition can't stay.

In the end, this night, the zombies attacked for 2 hours and 15 minutes, leaving 250,000 zombie corpses under the walls of the Iron Castle! The fifth offensive again ended in failure.
