And when "Confucian Wind City" entered the first level of combat readiness, the other three cities and "Dragon City" laughed at the fuss here at this moment, you must know that their city walls, after entering the battle, can be forty meters tall, and the thickness is nearly twenty meters.

Even if a large group of corpse tyrants come to attack the city, don't even think about shaking the city wall, plus all kinds of defensive equipment on the city wall, whether they can get close to the city wall is a problem, in this case, "Confucian Wind City" actually entered the state of first-level preparation, which really made them laugh off their big teeth.

Although it is said that "Confucian Wind City" has repeatedly emphasized that everyone should also enter the state of preparation, but under everyone's shirk, the other three cities don't take this matter to heart at all, let alone enter the first-level combat readiness state.

This time can be said to have passed very quickly, after the whole city of "Confucian Wind City" was nervous for a week, the people who took the water finally came back at this moment, and with the addition of these people, everyone breathed a sigh of relief.

At this moment, the four major cities not only have enough water resources, but also have more garrison forces, although after a week, everyone has long forgotten about that incident, but the equipment and personnel on the city wall have been in a state of battle, but they are reminding everyone that that incident is estimated to be much more serious than everyone thinks.

However, a week's preparation consumed one-tenth of the original energy of "Confucian Wind City", which made the bigwigs of other cities angry and funny, so angry that "Confucian Wind City" wasted energy, and it was funny that the dean of "Confucian Wind City" was too nervous.

While everyone waited to continue to laugh at "Confucian Wind City" and waited for "Confucian Wind City" to accept the punishment of "Dragon City", in a hidden clearing outside "Confucian Wind City", "Red Moon City", "Holy Fire City" and "True Martial City", there were countless zombies standing.

Why is it said to be a hidden clearing, it is because, above this clearing, there is a huge light mask, which can not only defend against attacks, but also hide the things inside, and it is precisely because of this that under the observation of the reconnaissance plane, there is no difference between this side and other places at all.

In fact, the movement here is bigger than anyone imagined, in which, in addition to a large number of zombies, there are also three-tenths of walking corpses, two-tenths of fighting corpses and demon corpses, and the most surprising thing is that there are one-tenth of the corpse tyrants and Xiaoqiang.

Don't look at one-tenth of it, it is very small, but in one-tenth of the tens of millions of zombies, that number is a bit terrifying, and this is only one of the positions, and above the other three open spaces outside the city, there are actually three of them with the same position.

If all four of them are gathered together, it is estimated that the largest "Dragon City" will be terrified, but according to the current formation, the purpose of these zombies is not in "Dragon City", but on the other four cities.

If everyone works together, it is still possible to hold a battle of this scale, but now, only "Confucian Wind City" has entered the first level of combat readiness, and the other cities have no defensive strength at all.

As for what this group of tens of millions of zombies are doing here, it is of course through excavation, preparing to give the four major cities a raid, you know, the machinery and equipment for fetching water have just returned, leaving a very huge passage on the road.

And the zombies only need to dig through the excavation to find this passage, then they are done, but under the zombie excavation with a bad brain, this progress is obviously a bit slow, otherwise, it is impossible to reach a week later, the zombies have not moved.

But one thing is certain, behind this zombie, there is a thing that makes all zombies feared and has a very high intelligence commanding them, for this thing, it is estimated that even the dean of "Imperial College" may not know.

~Boom————————! With the loud sound of an object collapsing, the walking corpses who had been in charge of digging inside also let out a cheerful roar at this moment, and under this roar, the leader also gave the order to attack very decisively at this moment.

Under the order, the tens of millions of zombie armies of these four phalanxes, like armies, walked into the cave in a very orderly manner, and the group of walking corpses, which was strong in defense and large in size, was placed at the front by this side as a meat shield.

After this walking corpse, there are zombies, fighting corpses and demon corpses, as for the corpse tyrant and Xiaoqiang, they stand at the back, not that the corpse tyrant is not good at fighting, but its size is too huge, if it is arranged in front, it will become a huge target.

It seems that this zombie leader is not only very smart, but also knows how to use the weaknesses and strengths of the troops, which is really terrifying, in fact, if it were not for the drilling equipment to get water, it would not be possible to leave such a wide passage underground.

This also leads to giving the zombies a chance to sneak attack quietly, and this passage is really huge, so huge that even the ten-meter-high corpse bully can walk in it, if this situation is known by the academy, I don't know if it will be angry to death.

Walking underground, not to mention how secretive, in addition to the exit is blocked by a large amount of heavy steel, even if there is a little sound from inside, it is blocked by steel and dirt.

As time goes by, the day is coming to an end, and at this moment, it is the time for all human beings to rest, and it is also the time when everyone is the most tired and sleepy, but at this time, a large number of zombies have gathered in the underground outside the four cities.

It is estimated that it is to let all the zombie army behind gather, all until two o'clock in the morning, this zombie army is still desperately assembled, it can be said that this time the zombie army is prepared, if so many zombies are not in a city, then this leader can really die.

~Wow——-! Boom, boom, boom.............

It was almost four o'clock in the morning, when everyone was sleeping soundly, and a roar instantly spread throughout the entire heaven and earth, and the army of tens of millions of zombies hiding underground also destroyed the exit at this moment and came to the ground.

And the corpse tyrant and Xiaoqiang in the back, at this moment, jumped hard towards it, this jump can be described as earth-shattering, and the very thick ground was actually directly penetrated by them.

As the corpse tyrants jumped out of the ground and came to the ground, Xiao Qiang, who could fly, also instigated his heavy wings at this moment and flew into the air, as for the fighting corpses and demon corpses, it was amazing, and he actually began to form a formation on the scene, as if he was gathering something.

"Ding! Global Announcement: Please gather at the city wall, and resist the siege of the zombie army, since this siege is an emergency, reward everyone for killing a zombie for each zombie experience value is twice the usual, and the explosion rate is increased by 10%. ”
