David's learning ability is extremely terrifying, thanks to his powerful spirit, three long-range sniper guns under his control will fire every few seconds.
The Shadow Attendant judges the position of the first-level Zerg in the air, and David manually enters the coordinates on the controller according to the observed position, which reduces the aiming time of each long-range sniper gun and increases the number of attacks.
Outside the city walls, as the explosive beetle was killed more and more, the green poison mist became thicker and thicker, almost reaching the level of affecting the sight.
Even part of the green poisonous fog floated over the city walls, and even in the No. 5 sniper control room where David was located, a faint green poisonous fog began to appear.
The protective military uniform on David automatically turned on the internal circulation mode, and the internal vitality system provided the required oxygen.
This technology of generating oxygen has reached its peak long ago, relying on the energy block on the protective uniform, as long as the energy is not consumed, oxygen will continue to be supplied.
So David didn't have to worry about what harm the green poisonous mist would do to him.
But the increasingly dense poisonous fog has affected his speed of discovering the first-class Zerg.
"Washing mode is on!" Hearing the notice from the operation room, in the shadow attendant's field of view, a lot of small holes appeared above the city wall, and these small holes sprayed out pieces of mist.
These water mists merged with poisonous mists, and turned into green water to fall to the ground.
It seems that the city defense system has a long-term response to poisonous fog. Think about it too. The Federation has been fighting the Zerg for thousands of years. During this period, the means against the Zerg have long been prepared.
The exhaust system in the control room also started to work, and the indoor poisonous mist was discharged.
When David first came to participate in the city defense, he was still a little nervous, but this time he hadn't felt that way long ago.
To be honest, the city defense battle is safer than the battles he experienced in the phantom.
Those powerful first-class zergs were either cleared by heavy laser guns or blown into pieces by Gaussian guns, and those that could escape were named and cleared by long-range sniper guns.
The entire combat process is sitting in front of the display screen, through the control device in your hand to complete.
When he received the order, he didn't even come home to get the weapon, but now he found that he had no chance to use the second-level sword and the second-level spear.
Besides, David also has the name of self-knowledge. Although he has a cold weapon control ability comparable to that of armor, he does not have armor exoskeleton armor, and is enemies with the first class Zerg, which is the result of being crushed .
"Warning, warning, the No. 5, No. 6, and No. 7 long-range sniper guns are overheating and are cooling. The cooling process takes one hundred seconds!" Just ten minutes after David attacked continuously, a row appeared on the screen in front of him. prompt.
Then all three of his long-range sniper guns lost control.
Shaking his head, David released the controller in his hand.
At this moment, the Shadow Attendant saw the Zerg begin to retreat, and soon disappeared into the field of vision.
"This is over?" David said to himself in doubt.
However, the identity bracelet still shows the call, he still has control of three long-range sniper guns, and the Zerg attack should not end so easily.
At this time David received a video call request from his father Hans, and he chose to agree.
"David, where are you?" Hans' figure appeared on the identity bracelet, but he stopped after only half of what he said, because he saw David's environment.
As a veteran who participated in many wars, he naturally knew where David was.
"Why are you in the sniper control room of the city defense?" Hans asked anxiously.
"Father, I was called up. It's safe here. Are you safe with Aunt Bertha and Little Edie?" David didn't say much about his situation and asked instead.
"We are all well, and we are all transferred to the shelter." Hans replied, while inquiring about David's situation with his own authority. As the guardian of David, he has the right to query all the information of David.
But he did not expect that David would be the object of being called.
Soon he saw the reason for the conscription, specializing in sniper, has the potential to sniper armor.
This made him happy, because he was able to get the title of "Kingdom" because of his sniper ability, which shows that his son inherited his talent.
As for the call for war, if it is a call for melee armour, then the danger is still very great, but the call for snipers is relatively safe.
Besides, if even the sniper control room is threatened, it means that the city cannot defend, and it will be equally unsafe in the city by then.
Thinking of this, Hans relaxed slightly.
"David, you pay attention to safety. When using long-range sniper guns, don't attack at full load. How many long-range sniper guns do you control now?" Hans asked very professionally.
"I'm controlling three long-range sniper guns now!" David also heard Hans's words and answered quickly.
"City defense is really crazy, let you recruit a newcomer to control three long-range sniper guns!" Hans complained when he heard the result, and then he said: "Three long-range sniper guns should keep firing at least once every 15 seconds. Do not increase the frequency. The alloy of the long-range sniper can not withstand continuous overclocking attacks. In addition, you must ensure that once a zerg rushes to the city wall, there must be a long-range sniper to protect your control room. "
David was stunned for a while. He also understood the problem of overheating of long-range sniper guns from the previous battle. As long as you think about the continuous battle, you can't fire it for 100 seconds, it will definitely be a disaster.
But he never thought of using a long-range sniper gun to defend his control room.
"Once the control room is broken by the Zerg, you can adjust the temperature of the protective clothing to zero, keep your body still, and have a certain chance to avoid the Zerg attack on you." Hans continued.
This method is a method of pretending to be dead, and makes the Zerg think it is a corpse, so that there is a certain probability that the corpse will not be destroyed.
Because when the city defense was broken, there were lively life everywhere, and the Zerg had more and better goals.
Of course, this method is also inferior to the military, but David is not a real soldier, the most important thing is that David is his son.
He paid everything for the Federation, including the body, including the family. He did not want his son David to die in war before he reached adulthood.
Even if he is the title of "Kingdom", the selfishness in his heart still exists.
"Father, I know it!" David responded with a deep voice. He then said softly, "Father, if the city defense is broken and you have no chance of evacuation, then take Auntie and Edie to this address. I prepared a little here Means to leave safely. "
As the message was sent, the location of his shelter was over.
"David, you have grown up!" Hans laughed loudly. He was a warrior crawling out of a dead body. He didn't care about such small things as Zerg attacks, but David's concern moved him particularly.
As for David's safe way of leaving, Hans didn't ask too much. The child always has his own secret when he grows up.
"Father, I will explain to you when the war is over." David finally said before disconnecting the video call.
After finishing the call with Hans, David sat in the No. 5 sniper control room and felt the responsibility for the first time. Behind him was his father, his relatives, and his friends.
Just thinking about it, there was a situation outside the city.
Near the city wall twenty meters away, a larvae drilled out of the ground.
Within 20 meters outside the city wall, the ground is reinforced with special alloys, so if these larvae want to be close to the city wall, they must drill the ground from 20 meters away.
These larvae are not the same as those that David has seen before. These larvae are no longer earth gray. Under the earth gray shell, the dark green blood makes the shell show a strange color.
David's identity bracelet also received the name and introduction of the larvae. Corrosive mutant larvae, special zergs mutated from larvae, have no combat power, but after the body is broken, it will produce strong corrosive liquid.
Although his three long-range sniper guns have been repaired, he saw in the aiming system that a prompt to prohibit attack appeared on these corroding mutant larvae.
So all he could do was watch these corroding mutant larvae emerge from the soil one by one, and then approach the city wall.
