The second line of defense in this battle had a frontal width of 2,000 meters and a depth of 800 meters.
Within this area, many deep pits more than ten meters deep were dug in various directions. The pits are connected to each other by numerous wide or narrow passages.
For intelligent humans, passing through these passages connecting the pits is not difficult at all. Humans can not only run fast on these twisted passages, but can even drive heavy trucks on these passages.
But for zombies with one muscle, if a few zombies are allowed to walk, they may be able to turn and pass normally. But for the huge group of corpses that are attacked by the tide, it is a nightmare.
Because they cannot pass in an orderly manner at all. In corners or narrow areas, zombies in front can easily be pushed by zombies behind and fall into deep pits.
Even if these zombies who fall into the pit don't die, they will be trapped inside. Humans will kill them slowly and take away their energy cores after large battles.
After Qin Kedi issued the order to retreat to the deep pit area, the six forces participating in the battle quickly entered their defensive areas.
Yunling City, which has the strongest individual strength, is responsible for the defense of the middle 400-meter battlefield.
There are about twenty ground passages in this area. Each channel starts with a width of four to five meters.
There are endless deep pits between the passages.
Ten thousand Yunling City elites were divided into twenty teams. Each team of 500 people has at least 150 second- and third-level spiritual warriors, and the rest are all third-level warriors.
Each team retreated thirty to fifty meters into the passage before engaging in contact combat with the forcibly diverted zombies.
Fighters wearing protective armor stood in the middle of the passage and blocked the charging zombies. The spiritual warriors behind them were paying close attention to the zombies with supernatural powers in the zombie team, and were ready to suppress them at any time.
The fighters at the front were all standing in the two to three meter area in the middle of the passage. Because they are also worried that they will lose their footing and fall into a deep pit. The fighters standing on both sides were holding large iron guns or spears three to four meters long, trying to prevent the zombies from getting too close.
Zombies don’t have that much consideration. As long as there is someone in front of them, as long as there is a gap in front of them and a place to stay, they will move forward without thinking. Even if the edge of a deep pit lies ahead, they are fearless.
This situation is very beneficial to mankind. The human warriors only need to knock down the zombies standing in the middle of the passage, and those zombies just tilt left and right, which is enough to force the zombies standing on the edge to become unstable and fall into the pit.
So while humans are fighting and retreating, and the zombies are pressing forward step by step, the zombies are quickly falling into pits and reducing in number. This attrition rate is two to three times faster than when they pass through the steel plate bridge.
Zhao Xuan, who was in the central passage of the battlefield, was directing the battle in his own passage while paying close attention to the entire battlefield.
After the battle lasted for more than ten minutes, Zhao Xuan finally showed a relaxed look on his face.
Humanity's current play style actually has one of the biggest weaknesses, and that is that the formation cannot be disturbed at all while it is steadily retreating. If the human formation is disturbed, for example, the zombies continue to play throwing and let the zombies 'airborne', then the human formation will be in chaos, and the human soldiers will fall into the trap one after another.
But the wisdom of the corpse king on the opposite side is limited after all. It only saw that its team was advancing all the time, and was not aware of the huge losses of the zombies. It took no immediate targeted measures.
Precisely because the Space Corpse King did not react correctly, after the humans retreated half of the distance into the pit, the number of corpses was reduced by another two to three hundred thousand.
Only a handful of these reduced zombies were killed on the passage roads, but the vast majority fell into deep pits and were divided and restricted by many deep pits.
"The victory of this battle is determined!" Zhao Xuan immediately came to a very firm conclusion.
Not only Zhao Xuan, but also the leaders of other forces saw this trend, and they all couldn't help but beam with joy.
Another ten minutes passed, and the major forces completely withdrew from the second line of defense, the deep pit defense line, and entered the third line of defense, the wide wall defense line, at the cost of very few casualties.
All the zombies quickly passed through the pit area and approached the wide defensive line.
At this time, the number of corpses was only about 200,000. The remaining more than 400,000 zombies are trapped in the vast pit.
The organizers of this battle finally saw the dawn of victory.
But the Space Corpse King doesn’t think so. In the consciousness of the Space Corpse King, it still has countless subordinates.
As the Space Zombie King roared, two hundred thousand zombies rushed into the wide wall area like a tide, rushing towards the wide wall that was just around the corner.
Because fresh blood that can drive them crazy is standing on the wide wall.
Unfortunately, after they actually rushed in, they discovered that they couldn't reach the blood food on the two or three meter high wall.
Ordinary zombies roared and clawed desperately to destroy the wide wall, but they were randomly stabbed by human warriors holding spears and spears on the wide wall.
The supernatural zombies launch long-range energy attacks against the humans on the wide wall. Although they can hurt some powerful warriors and even unlucky spiritual warriors, they will soon be killed by concentrated fire from the human spiritual warriors.
The rate of human casualties is gradually increasing, but the zombie casualties are even greater. The number of two hundred thousand zombies is rapidly decreasing at a speed visible to the naked eye.
At this time, Zhao Xuan, Yan Chengfeng and others had gathered together.
They all stopped taking action and began to recharge their batteries for the next attack on the zombie leadership.
When the brutal wide wall attack and defense battle lasted for more than half an hour, and when the zombies were about to kill through the wide wall area and reach the city wall, there were less than 100,000 zombies left.
The group of corpses became noticeably thinner.
"I saw the target." Zhao Xuan suddenly pointed to a place and said.
Everyone looked up and saw a bunch of zombies with special appearance and special movements in the center of the zombie team.
Although they had been searching hard before, there were too many zombies and the battlefield was too chaotic for them to find it.
Now that there are fewer zombies, the leadership of the zombies has been exposed.
"There are more than a hundred of them, they should all be tough characters." Sikong Zhen frowned slightly.
"That's right. They are all super zombies, and at least 20 of them are level four super zombies." Qin Kedi's face was a bit grim.
The expressions of others also became heavy.
Those elite zombies can easily deal with them with missiles, but other methods are not very effective. They can only kill them face to face.
However, when it comes to killing by force, only Zhao Xuan and Hei Yun on their side are at the fourth level, while the others are at the top of the third level. If you really want to go up and kill them, there may be a lot of casualties.
The casualties this time will not be casualties of physical warriors or ordinary spiritual warriors, but actual casualties of absolute elites.
Maybe even their own lives will be in danger.
