Zhang Yi was not particularly worried about Xing Tian and others appearing in the back mountain.
When building the defensive line, he had already considered the issue of the mountains behind.
The place was easy to defend but difficult to attack, and he planted many trigger mines on the mountainside.
If you make an emergency landing from that place, there is no good way to clear the mines, and you will have to be blown up alive.
"The enemy has appeared, prepare to fight!"
Zhang Yi shouted in a deep voice on the communication channel.
Everyone in the shelter was extremely focused at this time.
This battle can determine life and death!
"Boom!"
The tank teams from Yangsheng and Chaoyu bases have already advanced towards the outer perimeter of the shelter.
All soldiers are fully armed, wearing combat uniforms and holding modern weapons and equipment in their hands. It can be said that they are armed to the teeth.
There are powerful aliens in the secret, ready to take action at any time.
No matter how they look at it, they all feel that they will win this battle!
The followers of the Snow Worship Sect approached from the other direction step by step, holding primitive weapons such as firearms and even broadswords and spears.
The distance was getting closer and closer. When the front row of tanks reached 300 meters away from the defense line, Zhang Yi suddenly shouted: "Do it!"
At the console, Yang Xinxin decisively pressed the button in her hand.
Facing the direction of Yangsheng Base and Chaoyu Base, cracks suddenly appeared on the snow wall, and the ice was pushed open by huge gun barrels and muzzles.
Suddenly, the deafening sound of gunfire resounded throughout the entire front line!
Even vehicles loaded with heavy armor could not withstand the bombardment of large-caliber artillery and tank main guns, and were sent flying backwards, slamming into the cars behind them!
"boom!!!!"
"boom!!!!"
"boom!!!!"
The deafening explosion shocked all the forces!
"Artillery! Tanks, and machine guns! My God, where did they get these weapons?"
Immortal Zheng Yixian was stunned.
Fortunately, his men moved slowly and did not get close to the defense line. Otherwise, facing such fierce firepower, everyone would become a target!
Xiao Honglian and Wei Dinghai were also shocked and couldn't believe their eyes.
These heavy firearms are only held by Xishan Base in the entire Tianhai City.
"Could it be that... they looted the weapons depot at Xishan Base?"
"How on earth is this done?"
The firepower of Xishan Base exceeds the entire Tianhai City!
However, because heavy firearms are difficult to transport, they are difficult to actually apply on the battlefield.
However, today, they turned out to be the first batch of people to test the cannon!
"Spread out immediately and fight back!"
At this time, they had no time to be shocked. Xiao Honglian and Wei Dinghai hurriedly ordered their men to spread out and fight back.
But they were caught off guard in the first wave. Many people were beaten to pieces and tanks were blown up!
"This defense line is just an ice wall. If you blast it to pieces, you can get through! As long as we can get close to that shelter, we will win."
Xiao Honglian said with cold eyes.
Although she was caught off guard, she did not panic.
Because Wu Huairen told her that this shelter did not have a weapon system, it was just a solid shell.
So as long as they break the outer defense line, their chances of winning are infinite!
The soldiers on the chariot were afraid of being beaten, so they quickly jumped out of the chariot with their weapons in hand.
But as soon as they left the chariot, they immediately became Zhang Yi's targets.
Zhang Yi stood calmly in the attic, protected the window with a dimensional door, and then started sniping.
The process of sniping enemies is a bit boring.
Just aim, pull the trigger, and reload.
Every time this action is repeated, a soldier's life will be taken away.
Since the end of the world, Zhang Yi has become proficient in using sniper rifles to the point of instinct.
On average, he kills an ordinary soldier every three seconds!
As for Yangsheng Base and Chaoyu Base, because they did not predict that Zhang Yi had a large number of heavy firearms, the losses were extremely heavy!
Their modified tanks cannot withstand artillery fire.
Even the artillery carried on the vehicle for sieges was destroyed directly on the trailer before it even had time to be towed off!
On the back mountain side, Xing Tian, who originally planned to watch from the sidelines, couldn't help but swallowed his saliva.
"I've been wondering why Zhang Yi dares to confront so many forces at the same time. It turns out that he has such a hidden skill!"
He was secretly glad that he had the wit to go to the back of the shelter to catch fish.
However, he still said to his subordinates:
"Brothers, shoot! Make the noise louder. But be careful not to shoot at others!"
A bald man next to him scratched his head: "Boss, where is anyone around here?"
Xing Tian gave him a slap on the head: "If you are told to shoot, shoot. There is so much nonsense! In short, don't hurt anyone."
"I, Xingtian, am a man of iron bones, and I keep my word! We must do our best when we take other people's things."
"Unless Zhang Yi is defeated, we will not add insult to injury!"
As a result, intensive gunfire rang out from the back mountain, and those who didn't know thought they were launching an urgent attack.
But on the front line, the fighting was really fierce.
The two major bases were caught off guard by Zhang Yi, causing heavy casualties.
Zheng Yixian was worried that he would be suspected if he did not take action, so he directly ordered a group of believers to attack the defense line.
Even though there were hundreds of believers armed with various cold weapons and crude firearms, they roared and rushed towards the defense line.
In front of the shelter is a flat open space with no cover at all.
They rushed over, but before they got even 100 meters closer to the defense line, they were directly beaten into pieces by machine guns.
Zheng Yixian frowned. He didn't expect Zhang Yi to be so ruthless and not give him any face.
But considering that acting requires a complete performance, he had no choice but to hold back his emotions.
"We can't continue like this. We miscalculated the firepower configuration of this shelter!"
Xiao Honglian gritted his teeth and looked at the many soldiers who were killed by the bombing, and he began to regret it!
If they had known that Zhang Yi had such strong firepower, they would have come back better prepared.
But who would have thought that a team temporarily formed by a warehouse manager in the apocalypse would have the firepower that a militarized army can possess?
At this moment, Wei Dinghai's voice came to her ears.
"We must work together to break through this outer line of defense!"
"Most of their firepower should be here, and they don't have enough manpower. As long as they break through the defense line, they will be at a comprehensive disadvantage."
"You cover me with fire, I'll deal with it!"
Xiao Honglian said immediately: "Okay!"
Wei Dinghai's [Snow Lord] can work wonders at this time.
She immediately ordered everyone: "Carry out fire suppression and cooperate with Chaoyu Base to attack the ice and snow defense line!"
The Snow Worship Sect and Qingwei Base also received their requests.
Zheng Yixian kept a cold face and continued to ask his followers to die.
But Xing Tian just laughed and asked everyone to point their guns in the sky and fire.
On the position of Chaoyu Base, Wei Dinghai's whole body was covered by a layer of crystal armor of ice and snow, and then his whole body slowly merged into the ice and snow of the earth like mercury pouring down the ground.
On the defense line outside the shelter, the guns and cannons were still spewing tongues of fire, wreaking havoc on the three forces in front.
But suddenly, a sudden change occurred!
Without any warning, a wall of ice and snow exploded with a "Boom!"
Sharp snowflakes flew everywhere like flying knives, and an artillery piece behind it was also directly overturned.
"Um?"
Zhang Yi and others also noticed the changes here.
There was no warning, why did it happen suddenly?
While the ice and snow were flying, Zhang Yi saw a figure covered in thick ice and snow armor.
There was a hint of sarcasm in the corner of Wei Dinghai's mouth.
"In the world of ice and snow, I am the king!"
Machine guns and artillery are okay against ordinary people, but they are meaningless against powerful ice and snow aliens like him!
Because the distance was too far, Zhang Yi was unable to activate his divine power.
However, after Wei Dinghai opened a gap in the defense line, the coalition forces were already excited and rushed towards this direction with roars!
Within a few moments, thousands of soldiers would cross the ice and snow defense line and rush into the shelter.
Wei Dinghai continued to attack. After pressing his right hand on the wall, his supernatural power was activated. The huge ice and snow barrier exploded like paper!
The steel frame in the middle lost its support and collapsed.
Even Zhang Yi couldn't help but shrink his pupils when he saw this ability.
Wei Dinghai's ability is many times stronger than Fatty Xu's!
