Wu'an City is 120 kilometers north of Zhenjiang City.
On the edge of the southern urban area of Wu'an City, hundreds of thousands of human troops gathered here.
These human armies come from Zhenjiang City and originally belonged to major bases in Yunhai City.
Three days ago, Zhao Xuan suddenly invited the leaders of other major forces who had moved to Zhenjiang from Yunhai City to gather in Yunling New City.
Zhao Xuan showed Qin Kedi and others the huge power generation capacity and huge traction capacity of the crystal energy engine. At that time, Qin Kedi and other powerful leaders wanted to possess it.
Then Zhao Xuan made the request smoothly. This time, he does not need the crystal cores from various forces to exchange for the crystal energy engine. Instead, he needs to form an alliance with the major forces to capture Wu'an City.
After taking Wu'an City, the crystal cores can be divided however they want according to the rules, but the inventory of the military special tire factory in Wu'an City must belong to Yunling City.
The major forces naturally agreed to Zhao Xuan's request. Those special tires may be of great use to Zhao Xuan, but they are dispensable to them.
So in order to get a free crystal energy engine to go back and do research, the current battle was formed.
At the moment, on the edge of Wu'an city, as usual, more than 5,000 earth-type spiritual warriors are vigorously creating deep pits and traps.
"What the hell, why are these people so haunted? I just said to gather zombies here, and they actually came here again. Could it be that Zhao Xuan is keeping an eye on my whereabouts and knows that I am here?" Ao Yonghe hid in the dark and watched the actions of the coalition forces, feeling angry and hateful.
After the zombies in the city of Zhenjiang were wiped out by the human coalition last time, he was temporarily quiet for a while, and took advantage of this time to continuously inspect the surroundings of Zhenjiang.
He not only wanted to find where the corpses were plentiful and powerful, but also made a plan to gather the corpses and take them to a place where they could sneak attack on Yunling City's new base and hide them.
He finally decided to 'collect' the zombies in Wu'an City and brought these zombies one after another to the surrounding areas of Yunling City's new base. But just as he started to take action, Zhao Xuan caught up with him relentlessly.
Little did he know that this time it was a complete coincidence. Zhao Xuan had no idea that he was among the corpses in Wu'an City.
Zhao Xuan simply took a fancy to the large amount of inventory in the warehouse of Wu'an Military Special Tire Factory. He only summoned the coalition forces again because he didn't want to waste time.
With only the power of Yunling City to deal with the more than two million zombies in Wu'an City, Zhao Xuan still felt that he was not equipped enough and was in great danger.
As more and more zombies enter level five during this time, the overall intelligence of the zombies seems to have improved, and all kinds of strange zombies have begun to appear in large numbers. For example, poison zombies, flying zombies, sharp arrow zombies, giant zombies, crawling zombies, heavy artillery zombies, meat mountain zombies...
These different types of zombies have different attack characteristics, which have caused headaches for all human survivors.
Zhao Xuan used the crystal energy engine as bait to summon the coalition forces as a precaution.
Ao Yonghe, who didn't know the inside story, was furious as he watched from a distance that the human coalition forces started to use their old tricks to create deep pits and traps again.
But the next moment, a sinister smile appeared on his face.
He thought about the new situation emerging among the corpses.
Among the groups of corpses everywhere, there were many and some few of those special zombies, and some groups of corpses didn't even have one at all. But what a coincidence is that there are a lot of these special zombies in the urban area of Wu'an.
"You pesky guys, just wait for me. I will definitely cause you heavy losses today. Even your whole army will be annihilated." Ao Yonghe gritted his teeth secretly.
At two o'clock in the afternoon, more than 5,000 earth-type spiritual warriors worked non-stop and finally completed the pit trap.
This time the pit trap is still three thousand meters wide, but its depth reaches an astonishing five thousand meters. Because everyone knows that the corpse group in Wu'an City is a bit special, they are worried about something unexpected happening.
Only by making the depth of the pit and trap larger can they have enough room for changes.
And the battle that followed showed that their precautionary actions were indeed not in vain.
After the trap was laid, the coalition forces immediately began to attract monsters.
Ao Yonghe summoned a group of specific types of zombies to lie in wait and did not interfere with the coalition's monster-baiting operations. The coalition forces also successfully led the corpse group to the edge of the pit half an hour later.
The brutal pit attack and defense battle began immediately.
Zhao Xuan still led the Yunling City troops to guard the 20 middle passages of the trap. He led the team of men he commanded and retreated fifty meters along a passage, then stopped and prepared to fight the zombies.
According to the usual tactics, zombies rushing towards this passage will rush forward mindlessly along the passage. During their forward charge, many zombies will be squeezed into deep pits by their own kind, resulting in attrition.
But nothing like that happened today.
The zombies seemed to have suddenly enlightened. Instead of rushing up the passage in a swarm, they ran forward in threes and fives side by side.
"The wisdom of the corpses here is actually so high. It seems that today will definitely be a tough battle." Zhao Xuan's heart suddenly sank.
He quickly looked at the other passages and found that all passages were like this. Three or five zombies passed through the three-meter-wide passage side by side, with almost no possibility of falling into the pit!
"Fire with the level 4 crystal core crystal energy gun. Fighters should pay attention to intercepting the corpses." Zhao Xuan sighed inwardly and still issued the attack order.
'Shuashuashua...'
The muzzles of twenty crystal energy guns kept flashing with light. Bursts of energy flow immediately hit the zombies that were rushing forward.
Because there are as many as 150 passages, Zhao Xuan temporarily loaned out some crystal energy guns, resulting in an extremely limited number of crystal energy guns here.
Many zombies were killed immediately, but a small number of zombies were slightly injured and continued to rush forward.
These zombies that were not killed are all level five zombies.
"Fire with the level five crystal core crystal energy gun. Pay attention to the shooting accuracy." Zhao Xuan ordered again.
After zombies and mutated animals and plants have successively entered the fifth level, neither the Yunling City army nor other armies have fought an annihilation battle, so the number of fifth-level energy crystal cores in their hands is not too many, and they cannot load the fifth-level crystal cores. The crystal energy gun achieves unlimited fire.
Following Zhao Xuan's order, the muzzles of 20 more crystal energy guns continued to flash a slightly brighter light.
Under the powerful blow of the fifth-level energy flow, the fifth-level zombie that was only injured died quickly immediately.
The zombie's forward momentum suddenly stalled and was quickly pushed back.
Zhao Xuan just felt relieved when the situation with the zombies suddenly changed.
'Shuashuashua...'
As there was a faint sound in the corpse group, green mist-like substances suddenly appeared from the corpse group and shrouded Zhao Xuan like rain.
As soon as that thing appeared, the air was filled with an extremely fishy and nauseating smell.
Just a hint of it makes your head spin slightly.
"Venom zombies! Retreat!" Zhao Xuan hurriedly gave the order.
