The coalition forces on the passage were experienced in many battles, and they immediately saw that the green mist-like thing was not easy to deal with, and they quickly retreated.
"The wind spiritual warrior blows away the poisonous mist!"
Zhao Xuan gave orders while retreating.
Due to sufficient advance arrangements, each channel's combat team is equipped with as many spiritual warriors as possible with various abilities.
Although the number of wind spiritual warriors is relatively small, there are basically three or four in each passage.
'Hoo ho ho...'
The wind spiritual warriors in Zhao Xuan's team immediately took action.
The green mist was blown away immediately.
But this inevitably delayed the team's retreat. The distance between the forward zombies and the team was shortened by several meters.
Several fireballs, ice arrows, clods of earth, and the like immediately flew out of the corpse group and quickly hit the team.
These things contain strong energy and have very powerful power.
It was obvious that this was an attack launched by a level five supernatural zombie. If such an attack were to fall on the warriors in the front row who were responsible for intercepting the melee zombies, there would probably be casualties immediately.
"Back off again!" Zhao Xuan frowned.
The team immediately accelerated their retreat, but at least they were not hit by the energy attacks of the level 5 zombies.
Zhao Xuan glanced at it and saw that after retreating again and again, his team had killed less than a hundred zombies and was already forced to retreat almost fifty meters.
If the rest of the battle was like this, by the time he retreated through the five-kilometer-long deep tunnel, he would only be able to kill about 10,000 zombies.
Compared with the previous results, this is undoubtedly a shrinkage of five to ten times.
Despite this, if the 150 passages can achieve the same results, 1.5 million zombies can be annihilated when the coalition forces completely exit the pit area. If that really happened, Zhao Xuan could barely figure it out.
But Zhao Xuan glanced left and right, and his heart immediately felt cold.
The team he personally led had no casualties yet due to his proper command, but the other teams in Yunling City next to him killed not too many zombies, and some of them themselves began to be injured.
There were even small deaths among other forces further away.
The teams on some passages were overtaken by zombies and forced to fight hand to hand with them.
"Put up a wall of earth and ice to block the zombies, and take the opportunity to distance yourself."
Zhao Xuan felt anxious and immediately shouted with anger.
This shout was made by Zhao Xuan with all his strength, and it could be heard by everyone in the deep pit area.
The people leading the team in other passages secretly said, "Ashamed" and quickly ordered the earth and ice spiritual warriors to use their moves to stop the zombies.
Many of them were frightened by the zombies that suddenly became 'smart' and powerful, and were unable to adapt flexibly to the situation.
After the earth and ice walls were raised on each passage, although the zombies destroyed them very quickly, it would still take a certain amount of time. During this time, the humans who were stuck to the zombies regained a safe distance from the zombies and began to launch crystal energy gun strikes against the zombies again.
Zhao Xuan breathed a sigh of relief.
"Haha, now I'm starting to panic. Don't worry, the fun is yet to come. Just take your time and taste it." Ao Yonghe watched with great joy.
The group of special zombies he had summoned hadn't even taken action yet, and the human team was already a little overwhelmed.
But the already relatively intelligent corpse king in Wu'an City has more than that. In the future, humans will only become more and more passive.
When humans are at their most passive, Ao Yonghe will become the last straw that breaks the human coalition's back.
"Is it possible to kill Zhao Xuan today?" Ao Yonghe began to think about good things.
On the battlefield, Zhao Xuan had just breathed a sigh of relief, and suddenly realized that he seemed to have breathed a little prematurely.
When his team pulled away from the zombies and was about to use crystal energy guns to launch a sniper attack on the zombies that continued to advance, suddenly a group of zombies with wings on their backs rose into the air from behind the group of zombies, and a mass of darkness was directed toward Zhao Xuan's body. The team pounced.
At the same time, some zombies among the zombies that had evolved to very large sizes grabbed the zombies around them and threw them at Zhao Xuan's team.
"Flying corpse! Giant corpse!"
Zhao Xuan's expression changed slightly. He quickly looked at the battlefield and found that there were also zombies flying in the sky above other passages.
"Crystal energy guns, spiritual warriors volley and snipe! The ground continues to block."
Zhao Xuan shouted again, giving instructions to all teams on how to deal with the situation correctly.
When the situation suddenly changed, only a few team leaders on the channel relied on their rich war experience to issue correct response orders to their teams, but most of the team leaders were confused and at a loss.
Although Zhao Xuan's reminder was not slow at all, quite a few teams still had some zombies 'parachuted' into their teams, causing a lot of trouble.
In the chaos, some human soldiers were even forced into pit traps by zombies.
"Miscalculation. I'm afraid things will be a bit difficult today. I hope the zombies won't show any new changes." Zhao Xuan had a bad feeling in his heart.
However, today it seems that God must be against Zhao Xuan. He hoped that there would be no more new changes in the zombies, but new changes in the zombies were emerging one after another.
While the flying corpses among the corpses were still flying up, some special zombies with ferocious bone spurs all over their bodies rushed to the front of the corpses.
These zombies leaned forward.
'Shuashuashua...'
The bone spurs on the zombie's back flew away from the body, shooting at the human team like raindrops at high speed.
"Arrow zombies! Are there more heavy artillery zombies behind?" Zhao Xuan's face suddenly became solemn.
Arrow zombies and heavy artillery zombies are the most special variants among zombies. These two are not supernatural zombies, but they can use the organ parts on their bodies to launch long-range attacks, and the attack range is much farther than the supernatural zombies.
Their methods are also mass killing methods.
If their attacks were relatively easy to dodge in a normal wilderness, it would be quite difficult to dodge their attacks in this narrow passage.
"Shield is blocking." Zhao Xuan's mind was whirling as he loudly commanded the audience.
This time, many teams reacted correctly, using their shields to block the bone spurs shot by the zombies with sharp arrows.
But Zhao Xuan's mood was not relaxed at all.
The shield can block the bone spurs of the sharp-shooting zombies, but it cannot stop the heavy-artillery zombies, especially the biochemical energy shells emitted by the fifth-level heavy-artillery zombies.
Zhao Xuan is now unable to launch a counterattack against the zombies. If he actively searches for the heavy artillery zombies, he can only closely guard against the appearance of the heavy artillery zombies.
In Zhao Xuan's defense, the team quickly retreated while dealing with various crises, and soon retreated nearly two thousand meters.
To Zhao Xuan's relief, no heavy-artillery zombies have appeared so far.
"Is it possible that heavy-gun zombies haven't evolved among the zombies here?" Zhao Xuan couldn't help but think.
However, at this moment, Zhao Xuan's expression suddenly changed.
From a distance, he saw among the zombies a special zombie that was as threatening as the heavy artillery zombies striding forward.
