As the roar fell, countless pale skeletons poured out of the spatial crack, which was immediately captured by the drone hovering outside the crack and transmitted back to the command headquarters in the rear.

The big war is about to break out, and the skeletons are not as terrible as imagined, and humans can easily destroy the skeletons that rush out of the spatial rifts with thermal weapons, even those cracks with a diameter of more than a kilometer.

But there are so many skeletons that the rift is like a skeleton production machine, and no matter how many skeletons humans destroy, new skeletons will emerge from the rift.

The battle lasted for ten days and ten nights without a victory, the human soldiers changed batch after batch, and the bullets consumed alone exceeded 10,000 tons, and the guns were even more deformed by the overheating of the barrel due to the continuous shooting, and the scrapped guns were piled up into a hill, which was still a crack with a diameter of no more than 100 meters, and the consumption of those with a diameter of more than 500 meters was even more than dozens of times.

Such a huge consumption even a military power that has not experienced a disaster can not withstand it, let alone the sea blue star that has just experienced a disaster, some countries with relatively weak military strength have begun to ask for help from neighboring countries, and the leaders of those countries that have not seen cracks in their countries naturally understand the truth of their lips and teeth, and have sent troops with a large number of weapons and ammunition to assist in defense.

Leaders held video conferences almost daily to discuss countermeasures, and the most militarily powerful Stars and Stripes proposed dropping nuclear bombs into the cracks in an attempt to destroy them.

The Stars and Stripes were more unlucky, there were three cracks in the country, one of which was a kilometer in diameter, and the other two were also more than 300 meters in diameter, resulting in the consumption of ammunition faster than production, and the Stars and Stripes who wanted to save face did not ask for help from the host country, maybe they were really about to be unable to withstand it, or they were overconfident in their own nuclear bombs, and before the leaders of the countries discussed the results, they dropped a nuclear bomb on the smallest crack.

The effect was immediate, and there were no more skeletons pouring out of the cracks that had been attacked by the nuclear bomb, but the Stars and Stripes were horrified to find that instead of disappearing, the cracks expanded rapidly, until they were more than two kilometers in diameter, and even worse things happened, and the re-stabilized cracks were filled with hideous zombies in addition to the skeletons that were pouring out.

The new zombies are not only immensely powerful, but their bodies are as hard as iron, and small-caliber firearms can hardly do any damage to them.

The appearance of zombies is not only panicked by the Stars and Stripes who want to know the future troubles, but also by the leaders of other countries, although it is speculated that there is more than skeleton and a monster inside the crack, but there is some luck mentality, but a nuclear bomb in the Stars and Stripes country completely shattered this luck.

For the sake of the continuation of human civilization, the leaders of various countries finally decided to establish a human alliance after several fierce discussions, and establish a super giant city that can accommodate a billion people, so as to integrate the scattered forces and jointly resist the monster invasion.

Cities should be built far away from cracks, but also have water and fertile land, originally surrounded by the sea is the most ideal choice, but Australia is simply a paradise for atavistic beasts, and the center has a crack with a diameter of more than 600 meters, which was finally rejected.

Although there were only twenty cracks, there were not many that met the conditions for building a city, and after a lot of selection, it was finally decided to build the city in the south of the Dragon Kingdom.

Building a city that could accommodate a billion people was a huge undertaking, including almost the entire southern part of the Dragon Kingdom.

The global mobilization has begun, from national leaders to the elderly, weak women and children have joined in the construction, and no one has any reason to be lazy for the continuation of mankind.

As a large number of people and supplies were transported to the south of the Dragon Kingdom, after detailed planning, the entire south began to build on a large scale.

Although it is said to be a city, in fact, it is only necessary to build a wall that can resist monsters, and after a year's hard work, the concrete wall with a height of 100 meters on all sides and a thickness of 30 meters has been completed.

In the past year or so, the cracks with a diameter of more than 500 meters have been lost, and in order to buy time for the construction of the city, the human warriors can only fight and retreat, for which too many humans have sacrificed their precious lives.

Humans naturally don't devote all their energy to building cities, and researchers are naturally trying their best to find ways to make humans stronger, and by chance, human warriors found that monsters have a black crystal in their heads when cleaning the battlefield.

According to the research of scientific researchers, this crystal contains a special kind of energy, which can be absorbed by ordinary enhancers to strengthen the body, and after absorption, the supernatural person can not only strengthen the body, but also enhance the power of the ability.

One of the weapons design engineers even took a different approach, combining crystals and thermal weapons to invent energy weapons, which greatly reduced the need for ammunition on the front line.

After the completion of the construction of the city wall, all the human warriors retreated to the city armed to the teeth in an orderly manner, although there are cracks in the dragon country, but they are relatively small, and the monsters that have poured out for more than a year are only skeletons and zombies, plus the defense of a large number of human warriors, although there will be battles every day, but the pressure is not great.

Humanity has respite from respite, but this disaster is not so easy to solve, those monsters that come out of the cracks with a diameter of more than 500 meters are terrifying, and they can easily destroy a tank, ordinary shells can't kill at all, only the use of missiles can be killed, and some can even resist missile attacks head-on without dying.

Thankfully, these powerful monsters don't run around when they come out of the rift, but move around the area around the rift.

In addition, after a year, although a large number of monsters are pouring out every day, there are many fewer than before, which is also good news for humans.

In order to be able to train excellent warriors to fight against monsters from the rifts, the Human Alliance has established five military schools, and all young people who have reached the age of sixteen must enter the military academy to study.

Sea Blue Star also has five continents, and each continent has opened a military school, which is Dongzhou Longteng Military Academy, Nanzhou Victory Military Academy, Xizhou Royal Military Academy, Zhongzhou Dawn Military Academy and Beizhou Polar Bear Military Academy, among these five military schools, Longteng Military Academy is the most popular and strongest military school.

There are two reasons related to the big brother of Dongzhou, the Dragon Kingdom, the top military strength of the first Dragon Country, and the martial arts of the Second Dragon Kingdom, a large number of students apply for the Dragon Teng Military Academy every year, of course, it is not so simple to enter the Dragon Teng Military Academy.

The three do not block the vast majority of students outside the school gate.

Students with physical fitness below 20 will not be accepted.

Students who have not dedicated themselves to the Dragon Emperor City at any time will not be accepted.

Students without special skills are not accepted.

In addition, there is an unspoken rule: Dongzhou students are given priority.
