Chapter 770 The Battle of Defending the City Started

One night, everything was fine.

The 11th and 12th waves of zombie attacks that were originally worried did not happen.

With Liu Mingyu's current physical fitness, it is not a big problem to not rest all night, and there is still energy potion around.

Liu Mingyu checked the task countdown on the system interface for the first time 01:30:50

With only an hour and a half left, the system will turn on the zombie siege mode.

This night, the soldiers rarely got a good night's sleep.

After waking up in the morning, Ye Qingxuan had already asked the logistics staff to prepare breakfast and transport it to the city wall.

After hurriedly eating breakfast, I checked the weapons and ammunition again.

At night, Liu Mingyu had asked Ye Qingxuan's logistics staff to move all the ammunition in the warehouse to the city wall, and everyone was assigned the corresponding bullets and ammunition.

Fortunately, Liu Mingyu bought a lot of bullets and grenades from Austin Martin last time when he was in Sam Country, and this time he carried a lot of ammunition from Chen Wuqi and the others.

There are tens of thousands of bullets and hundreds of grenades around everyone, and in the warehouse not far from the city wall, a large amount of ammunition is stored in order to be able to provide support at the first time.

There are millions of bullets, hundreds of thousands of grenades, various armor-piercing rounds, etc.

With these ammunition here, Liu Mingyu has enough confidence to defend this zombie siege attack.

For this zombie siege, Liu Mingyu made a lot of preparations.

Unfortunately, this method of attacking in advance did not work, otherwise defending the city would be easier today.

Liu Mingyu looked at the time, only half an hour left.

A large number of drones were dispatched. It is daytime, and the field of vision is very good. From the Xingchen Group, you can clearly see the situation in every direction.

It can be considered to know each other.

Just as everyone was waiting for the attack of the zombies, suddenly, a loud noise sounded.

Everyone was shocked, because the direction of the loud noise was behind everyone.

Suddenly, everyone's eyes were attracted by the two iron lumps more than five meters high in front of them.

Gundam?

No, it's a combat intelligent robot.

The moment everyone saw the battle-type intelligent robot, they thought of the battle-type intelligent robot that the boss had shown not long ago.

They have seen the power of these combat intelligent robots.

The two five-meter-high robots moved forward slowly, and with every step forward, everyone seemed to be able to feel a vibration coming.

"Boss, this is a combat intelligent robot I built, and I want them to participate in this defense of the city."

Zhao Yulong pointed to two iron lumps more than five meters high behind him.

"Yes, no problem, but unfortunately there are only two. It would be better if there were a little more. If there are tens of thousands of combat-type intelligent robots, we don't need to take action. These combat-type intelligent robots can handle these zombies." Liu Mingyu Laughing loudly, he almost forgot about the battle-type intelligent robot.

Although there are only two, I believe that they can also exert a lot of power.

"Boss, there are actually more than two, there are a total of eight, and there are two in each direction. Unfortunately, there is not enough time. Otherwise, if the boss wants tens of thousands, it is still possible."

The main reason is that the zombie siege came too fast this time. If you give more time, it is not impossible.

These combat-type intelligent robots in Zhao Yulong's hands are actually made of some "garbage".

When manufacturing the first combat-type intelligent robot, it took a lot of time, but the second, third, and more and more combat-type intelligent robots will be manufactured faster and faster, because the Proficiency is increasing.

Liu Mingyu's eyes lit up, and he gave a thumbs up and praised: "Oh, there are eight stations, that's not bad."

The combat-type intelligent robot is relatively large, and its main attack method is melee attack, and it is not very useful to stay on the city wall.

Combat intelligent robots were placed outside the city walls as the first line of battle.

Time passed slowly, and everyone's heart was lifted.

Liu Mingyu was no exception, his eyes fixed on the countdown on the system interface.

10 seconds.

9 seconds.

8 seconds.

...

1 second.

"It has been detected that the host has successfully established a base, and the zombie siege mode is now officially launched. The zombie attack will be divided into 20 waves of attacks. Please keep the heart of the base, and defend the city successfully, and there are rich rewards."

"The first wave of zombie attacks has started, please prepare for the battle."

On the system interface, two messages flashed.

"Boss, there is a gap in the invisible barrier. Just like yesterday, a large number of zombies came out."

"Everyone, prepare to fight." Liu Mingyu said condensedly.

With an order, everyone stared at the front.

After countless zombies came out, they no longer walked slowly as before. All the zombies seemed to run fast as if they had turned on the acceleration plug-in.

Rumble.

Countless zombies ran quickly, like ten thousand horses galloping, and there was a loud noise.

"Pay attention to the interval between each wave of zombies' attacks. This time we need to face twenty waves of attacks." Liu Mingyu instructed the monitoring personnel on the side.

Not everyone came to fight on the city walls, everyone had a position for everyone, some were fighting, some were supporting in the rear.

Don't underestimate these auxiliary personnel, the strength they exert is not much less than that of the fighters.

Liu Mingyu only knew that there were twenty waves of attacks, and he didn't know what the time interval of the twenty waves was.

But soon, he knew that his worries were unnecessary.

Because after the first wave of zombies attacked all zombies, the system interface immediately displayed the countdown for the next wave of attacks.

30:00

That is to say, there is an interval of 30 minutes. If Liu Mingyu can kill these zombies in no more than 30 minutes, he can buy more rest time for himself.

I just asked the monitoring staff to calculate the interval between attacks, and he has not changed it.

The distance between the two sides is only a few kilometers away.

Don't think that the speed of zombies is slow. Only those who have encountered the zombie tide know how fast the zombies can run with all their strength.

A few kilometers away in a blink of an eye.

Liu Mingyu stood on the city wall, a breeze blew over, and he smelled a strong rancid smell blowing into his nose along the wind.

This is the rancid smell emanating from zombies.

Soon, the zombies entered the combat range.

Three hundred meters.

two hundred meters.

One hundred meters.

"kill."

Liu Mingyu roared and took the lead to shoot at the swarming zombies.

An incendiary bomb mixed with Liu Mingyu's anger rushed towards the zombies.

Boom.

Incendiary bombs explode in zombies.

The number of zombies in this attack was too many, and many zombies gathered together.

More than a dozen zombies around were set on fire by incendiary bombs.

The battle of defending the city of Xingchen Group started.
