Chapter 89 Guidance

David's ability to learn is extremely terrifying. Thanks to his strong spirit, three long-range sniper guns are fired every few seconds under his control.

Shadow Servant judged the position of the first-level Zerg in the air, and David manually entered the coordinates on the controller according to the observed position, which reduced the aiming time of each long-range sniper gun and increased the number of attacks.

Outside the city walls, as more and more poisonous blasting beetles were killed, the green poisonous fog became thicker and thicker, almost to the point of affecting the line of sight.

Even part of the green poisonous fog floated above the city wall, and even in the No. 5 sniper control room where David was, a faint green poisonous fog began to appear.

The protective military uniform on David automatically turned on the internal circulation mode, and the required oxygen was provided by the internal life support system.

The technology of this kind of generated oxygen has already reached its peak. Relying on the energy blocks on the protective military uniform, as long as the energy is not consumed, the oxygen will continue to be supplied.

So David doesn't have to worry about what harm the green poisonous mist will do to him.

But the thicker and thicker poisonous mist affected the speed at which he discovered the first-level Zerg.

"Starting the cleaning mode!" Hearing the notification from the control room, in the Shadow Servant's field of vision, many small holes appeared on the city wall, and these small holes sprayed out pieces of water mist.

These mists merged with the poisonous mist, turning into green water and falling to the ground.

It seems that the city defense system has long responded to the poisonous fog. Thinking about it, the Federation and the Zerg have been fighting for ten thousand years, and they have long been prepared for the means of the Zerg during this period.

The exhaust system in the control room also started to work to discharge the indoor poisonous mist.

When David first came to participate in the city defense, he was still a little nervous, but at this moment, that feeling has long since disappeared.

To be honest, the city defense battle was safer here than the battles he had experienced in the illusion.

Those powerful first-level Zerg were either cleaned up by heavy laser cannons or blown to pieces by Gauss cannons, and those who could escape were named and cleared by long-range sniper cannons.

The entire battle process is done by sitting in front of the display screen and using the controller in his hand.

When he received the summoning order, he didn't even have time to go home to get the weapon, but now he found that even if he took the second-level long sword and second-level spear, he had no chance to use it.

Besides, David also has a reputation for self-knowledge. Although he has the ability to master cold weapons at the level of the armored soldier, he does not have the exoskeleton armor of the armored soldier. He is the enemy of the first-level Zerg, which is the result of being crushed. .

"Warning, warning, the No. 5, No. 6, No. 7 long-range sniper guns are overheating, and they are cooling down, and the cooling process takes 100 seconds!" Just after David attacked for ten minutes, the display in front of him showed a row of hint.

Then all three of his long-range sniper guns lost control.

Shaking his head, David released the controller in his hand.

At this moment, Shadow Servant saw the Zerg start to retreat, and soon disappeared from sight.

"Is this the end?" David asked himself suspiciously.

However, the identity bracelet still shows the recruitment, and he still has the control of three long-range sniper guns. 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 halfway, because he saw the environment David was in.

As a veteran of many wars, he naturally knew where David was.

"Why are you in the city defense's sniper control room?" Hans asked anxiously.

"Father, I was called here. It's very safe here. Are you, Aunt Bertha, and little Edie safe?" David asked instead without saying much about his situation.

"We are all well,

were moved to shelters. "Hans replied, while inquiring about David's situation through his own authority. As David's guardian, he has the right to inquire about all of David's information.

It's just that he didn't expect that David would become the target of the call.

Soon he saw the reason for the recruitment, specializing in sniping, and having the potential to snipe armored soldiers.

This made him happy, because the reason why he was able to get the title of "national scholar" was because of his own sniping ability, which showed that his son had inherited his talent.

As for the war recruitment, if it is a melee armored soldier recruitment, then the danger is still great, but the sniper recruitment is relatively safe.

Besides, if even the sniper control room is threatened, it means that the city cannot be defended, and it will be equally unsafe in the city by then.

Thinking of this, Hans's nervous color relaxed slightly.

"David, pay attention to safety. When using long-range sniper guns, don't attack at full capacity. How many long-range sniper guns do you control now?" Hans asked very professionally.

"I'm in control of three long-range sniper guns now!" David also hurriedly replied after hearing the meaning of Hans's words.

"The city defense is really crazy, let you a recruited newcomer control three long-range sniper guns!" Hans couldn't help complaining when he heard the result, and then he said: "The three long-range sniper guns must keep firing at least once every fifteen seconds. Don't increase the frequency, the alloy of the long-range sniper gun cannot withstand continuous overclocking attacks, and you must also ensure that once a zerg rushes to the city wall, there must be a long-range sniper gun to guard your control room."

David was stunned for a moment. He also understood the problem of overheating of long-range sniper guns from the battle just now. As long as you think about the continuous battle, if you can't fire for 100 seconds, it will definitely be a disaster.

But he never thought of defending his control room with long-range sniper guns.

"Once the control room is breached by the Zerg, you adjust the temperature of the protective suit to zero degrees, keep your body still, and have a certain chance to avoid the Zerg's attack on you." Hans continued.

This method is a method of pretending to be dead, so that the Zerg thinks 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 fresh life everywhere, and the Zerg had more and better targets.

Of course, this method is also despised by the army, but David is not a real soldier. The most important thing is that David is his son.

He gave everything for the Federation, including his body, including his family, and he did not want his son David to die in the war before he became an adult.

Even if he has the title of "national scholar", the selfishness in his heart still exists.

"Father, I know!" David replied in a deep voice, and then he said softly: "Father, if the city defense is broken and you have no chance to evacuate, then bring Auntie and Edie to this address, I have prepared a little here. Means of safe exit."

Along with the message was the location of his hideout.

"David, you've grown up!" Hans laughed loudly. He was a warrior who climbed out of the corpse. He didn't care about the trivial matter of the Zerg attack, but David's concern made him particularly moved.

As for the means of safe departure that David said, Hans did not ask much, the child always has his own secrets when he is older.

"Father, when the war is over, I will explain it to you," 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 were his father, his relatives, and his friends.

Just as I was thinking about it, something happened outside the city.

On the ground twenty meters away from the city wall, one by one larvae burrowed out of the ground.

Within 20 meters outside the city wall, the ground is reinforced with special alloys, so if these larvae want to get close to the city wall, they must drill out of the ground from 20 meters away.

These larvae are not the same as the larvae that David has seen before. These larvae are no longer soil gray. Under the soil gray shell, the dark green blood makes the shell appear strange colors.

David's identity bracelet also received the name and introduction of this larva. Corrosive mutant larvae, a special zerg mutated from larvae, have no combat power, but after the body is broken, it will produce a strong corrosive liquid.

Although his three long-range sniper cannons had been repaired, he could see in the aiming system that a warning forbidding an attack had appeared above the mutated larvae.

So all he can do is watch these mutated larvae emerge from the soil one by one, and then approach the city wall.
