The city of Shanghai is huge, with a total of 16 municipal districts covering an area of 6,340 square kilometers, but it never seems empty, because this highly developed city has a population of more than 24 million, and everywhere you go, it is bustling with people coming and going, and the bustling area is full of high-rise buildings and constant traffic.

It wasn't until the evacuation of the entire territory began, turning the thriving capital into a silent city, that people realized how big and empty the city was.

Now, the situation has reversed, and the first cracks that appeared first filled Huangpu Road and quickly spread to the surrounding areas, threatening to cover the entire Hongkou District.

It didn't take long for the area to be filled with monsters bursting out of the cracks, huge monsters roaming the tall buildings around them, making the street lamps look like toothpicks under them, and tiny monsters shuttling between the streets and floors, curiously exploring new worlds.

When different kinds of monsters meet each other, sometimes they are safe and sound, sometimes they fight fiercely, and the seemingly never-ending roar resounds in all corners of the city. Because there was no smoke to cover up, there was only a strong and pungent smell of blood in the air.

Every once in a while, flares are dropped into the area, and when the time fuse ignites the illuminator, the parachute under the flare opens, causing the light box to slowly descend over the area and spread the incandescent light onto the ground, looking up at the dark city as if a small sun is falling.

This spectacle attracted the attention of many monsters, who, like refugees picking up airdrops, rushed to the location where the flares had landed to find out.

There are also a few powerful monsters that are not attracted by the flares, the powerful glimmer long-range vision allows them to see the "huge iron bird" whistling high above their heads, they don't know that it is the reconnaissance plane of the Nandu Military Region, in their understanding, it must be the indigenous creatures that belong to this new world, so they are driven by curiosity and desire to kill, and chase in the direction of the reconnaissance plane, and a few of them have the ability to fly monsters struggle to flap their wings, rise from the ground, and soar into the sky.

However, they were far from being able to keep up with the reconnaissance planes, and in the end, they had no choice but to give up, and when they returned to the ground, they immediately vented their anger on the buildings and other weaker monsters. They don't know that the relative slowness of their speed allows them to temporarily pick up their lives, and if they can catch up with the unmanned reconnaissance aircraft, then they will definitely be hit by an over-the-horizon strike by a fighter group on the way to the pursuit, and their lives will be killed.

The drone constantly hovered overhead, transmitting clear aerial footage back to the command and command center of the military region.

"Still haven't been ordered?"

Yang Xiaoqian looked at the picture in front of him and rubbed his eyebrows with a headache. At this time, an hour had passed since the first crack appeared, but all the troops were still standing still and not a single shot was fired.

It's all well that monsters kill each other, but there's always a limit to how much they can fight each other, and judging from the footage taken by drones and reconnaissance satellites, most monsters will choose to retreat when they encounter more powerful monsters.

Therefore, just because you watch from the wall doesn't mean you can really take the time to watch the monsters fight to the ground, as the cracks increase and the density of monsters increases, more monsters will only spread throughout the city and outside the city.

If we don't solve some of them now, and wait for tens of thousands of demons and monsters to storm the defense line together, even if we can hold the defense line, we will have to pay a heavy price, and no matter how valuable the missiles and shells are, they will not be worth the lives of more than 100,000 soldiers, so it stands to reason that the bomber brigade and artillery units should be allowed to attack now, but the military region has never issued an order to open fire, and no matter which unit asks for instructions, the only reply it gets is "stand still" and "stand by now."

"There are no instructions, so keep waiting." Pei Qingxian stood behind Yang Xiaoqian, also puzzled, thirty minutes ago he gathered all the troops in the hunter base, and each squad entered their own equipped vehicles and was ready to go, from armed helicopters to large transport aircraft, from main battle tanks to infantry fighting vehicles, to armored personnel carriers and heavy locomotives, giving every monster hunter who participated in the battle the ability to mobile combat.

But the troops who were ready to go waited for half an hour, but they did not receive a single order to go to battle.

"Then continue to wait, the commander-in-chief is Liu Yuanzhou, there will be no problem, Xiao Dan, please make me a cup of coffee." Yang Xiaoqian nodded, until now he was too lazy to ponder Liu Yuanzhou's thoughts, since Liu Yuanzhou chose to continue to wait, it means that continuing to wait can maximize the benefits, although Liu Yuanzhou's calculation may not always be correct, but the probability of being correct is definitely much greater than others.

When the crack appeared, Yang Xiaoqian had just fallen asleep, and he was awakened as soon as he put down his heavy work and closed his eyelids, and spent a monotonous and boring hour in a tense state, and finally felt a little sleepy, and needed a cup of coffee to wake up.

A few minutes later, when Xiao Dan came over with coffee, Yang Xiaoqian was no longer sleepy, because there was new news from the General Staff, three new cracks appeared in the Hongkou District, the largest crack reached an astonishing height of eighty meters, and the widest part was nearly fifty meters, as soon as it appeared, all the monsters within a radius of three thousand meters with the crack as the center began to move away from the area.

According to the experience of the defense of Nandu and the information given by Yu Qian, the larger the area of the spatial rift, the longer it takes for monsters to appear from it, and correspondingly, the stronger the strength of monsters, and they are often proportional to their size.

The last time the giant crack that appeared in the sky above Nandu was only more than fifty meters, it released a demon dragon, and the three spatial cracks that appeared in the Hongkou District were all more than fifty meters long.

This is not the most troublesome problem, what is even more worrying is that the appearance of these three giant cracks obviously stimulated other monsters, causing the monsters gathered in the Hongkou area to all flee in the direction of moving away from the cracks, and gradually converge into a vicious torrent, surging in the direction where the defense line is located.

Seeing the aerial footage sent back by the drone, Yang Xiaoqian finally knew why the humans of Earth No. 2 called this kind of disaster a "magic tide", even Pei Qingxian, a tough guy with iron bones, couldn't help but gasp.

………………

In the general headquarters, a thin young man sat in a wheelchair, and behind him, on the three-dimensional electronic sand table, countless red dots appeared at different heights and positions, and in front of him, thousands of screens recorded the swept away magic tide from different angles.

"Let's get started."

He spoke, then slowly stood up, standing up straight, and a silhouette was reflected on the screen,
