The city of Letus is about 70 kilometers away from where Liu Di is now, and it will take at least several days to walk there without transportation, because the neighborhood is covered with sand. If you have a vehicle, it should take about 1 day to arrive, and you have to take the right path.

Liu Di looked at the ghost head and asked, "You have experienced the battle between Letus City and the mutants, do you have any ideas?" ”

After hearing this, the ghost head said: "It can be seen that those mutants are all controlled, organized and staged attacks, etc., and those mutants don't seem to care about the dead corpses, it is more difficult to use the sniper rifle I am using now to hit those giant third-level mutants, and I have to shoot a lot of shots to knock down that kind of mutants." ”

As everyone pondered after the ghost head finished speaking, then Chang Ye came over and said, "Commander, everyone's bedrooms have been cleaned up, lunch has been prepared, please come to the restaurant to eat." ”

"Okay, I got it!" Liu Di said to this Changye.

Liu Di got up and said: "Eating is a major event in life, let's go eat first, and you can rest for a few days." ”

After lunch, Liu Di came to the command center located on the 5th floor of the basement, and watched the time on the construction page gradually decrease, Liu Di was also extremely excited.

Suddenly, JH said, "Commander, your next mission has been issued, please check it out for yourself." ”

After hearing the words of the base, Liu Di clicked on the mission interface:

Low-level permissions are advanced to primary permissions, the mine collects at least 1G of minerals per day, and gathers more than 50 basic troops and 100 survivors.

This task lasts for 3 months, and if you complete the task in advance, you can get a lottery chance and 20,000 gold coins.

After watching the task, Liu Di wanted to curse, the nearest city from here is 70 kilometers away, where are the survivors! Suddenly, he thought of something and asked JH, "I remember that the reward for least privilege is to get a random permanent building right to build a unit!" ”

"Is there such a thing?" JH said with some skepticism.

"Absolutely, hurry up the mission reward!" Liu Di stretched out his hand in the direction of the holographic projection.

JH looked at him with disgust and then said, "Then the construction unit will be drawn and opened!" ”

After speaking, 3 chests appeared on the interface used for the lottery, and before the drawing, they were displayed on them: Mineral Refinery, Soldier Training Ground, and Electric Drive Center.

"What is the base?"

"This is the upgrade driver of the building itself, please ask the commander to draw it." After JH finished speaking, the three boxes flipped over and began to refresh.

"I've chosen the middle!" Liu Di said.

The box in the middle suddenly opened, and the icon of the soldier training ground that I had just seen appeared inside, and the base said: "Congratulations to the commander for obtaining the soldier training ground, the soldier training ground is a soldier training center that the barracks think is, you can build it at will within the area where the base is located, this building must be used near the barracks, but it is not suitable for soldiers summoned from the barracks." ”

Liu Di wanted to curse after hearing this, what is the use of this thing, but he was relieved when he suddenly thought of his brothers, after all, his brothers still have to go on missions with him, and they usually need to train every day, so this building can't be considered bad.

The power plant was built first, and there was an elevator near the gate of the base, and after the power plant was built, the elevator suddenly started, and then several robots and a giant block were seen coming out from underneath.

Liu Di looked at the construction scope of the base and felt that the power plant should be placed closest to the base to ensure the power supply of the entire base.

The power plant was placed in a vacant lot behind the base, and then Liu Di clicked on the barracks and the wall, because the wall does not belong to the building interface, so it does not affect the construction. Liu Di set up a circle of walls and mechanical guard towers around the construction range of the base, the wall was 50 gold coins, and the mechanical guard tower was 150 gold coins, and the entire fence cost 2000 gold coins.

Liu Di looked at the 4600 gold coins left and felt a little heartache, but there was no way after all, I didn't know when the mutants would come around, so it was more reassuring to do this, the best thing was that the bullets in the mechanical guard tower did not accept gold coins, so Liu Di was still quite satisfied.

After the mine and barracks came out one after another, a villain's icon appeared on the interface of the control system, and then Liu Di clicked on it, and there were only two types of troops: military dogs and orderlies.

Each military dog is 100 gold coins, and the collection time is 30 minutes.

Orderlies are 100 gold each, and the collection time is 30 minutes.

Note: All units recruited from the base are full of living creatures, they all have their own minds, and their own minds, and all soldiers are absolutely loyal to their commanders, so please put them in perspective!

Although Liu Di was distressed, he still ordered 10 orderlies and 5 military dogs, and the gold coins on the top were only 3100 at this time, and when he saw that the soldier training camp only needed 100 gold coins, Liu Di clicked on the construction without thinking about it.

Suddenly, a rapid alarm voice came from the base: "Warning, the signal of a fourth-level mutant lifeform has been found, please pay attention to the commander!" ”

"Open the map!"

As soon as Liu Di finished speaking, the whole room dimmed, and a real-time picture of the fourth-level mutant appeared in the entire room. Fourth-level mutants and third-level mutants began to develop in an extreme direction, one was to shrink to the size of first-level mutants, and the other was to be larger than third-level mutants.

At present, what Liu Di sees is a fourth-level mutant who has developed into a small area, and this mutant is actually carried by two third-level mutants.

Within 100 kilometers of the base, the base can be seen through this real-time screen, and this range will gradually expand as the level increases.

"Can you analyze this fourth-level mutant?" Liu Di didn't know if the base had this kind of function, so he asked.

"Under analysis...... The results of the analysis show that the other party is a fourth-level mutant, with unknown abilities and commanding skills. ”

"Unknown ability?" Liu Di raised his eyebrows and said.

"Because the other side doesn't have the ability to use it, the base can't be predicted." JH said.

Liu Di watched it for a while and then turned off the real-time screen, and Liu Di found a small button under the column where soldiers were recruited. After Liu Di pressed it, a logistics supplies manufacturing area appeared, which included guns and cars, but at this time, only two guns were unlocked, and the cars were only civilian.

"Base, which of these two guns can injure a level 4 mutant?" Liu Di asked.

"The second type can injure level 4 mutants, but it is not recommended to use it in large quantities, this gun has a slow rate of fire, but it is extremely penetrating"

After hearing what JH said, Liu Di ordered 4 guns of each type, as well as thousands of bullets, and spent a total of 100 gold coins. Liu Di knew that this kind of gold coin could not be omitted, so he was willing to spend it.

Soon the weapons were sent to the ground through the platform outside, and everyone came out of the house.

Liu Di stood in front and looked at everyone and said: "The existence of fourth-level mutants has been confirmed, so we must be ready, here is the newly produced gun, the ghost head, the night shadow, the ghost ghost, the three of you are sniper-like guns, Tang Fan, ghost shadow, thunder shadow, black shadow, you take the rifle, Chen Ziyu and Yan Zhiwen, you two can continue to rest, ready to meet us at any time." ”

At this time, the bullet casings on the defensive line on the outskirts of Letus City had fallen to the ground and covered a layer, and the remnants of the feathers kept shooting and directing on the front line of defense.

The statement moved to the side of the remnant feather and said: "Commander, our ammunition can only hold up for 3 days, and after three days, we will not be able to withstand the bullets in our rear if they can't be transported!" ”

"What? Are the bullets depleting so quickly? Contact our logistics today to see when our supplies will arrive! "Remnant Yu knew in his heart that if there was not enough ammunition, this position would soon be attacked by mutants.

At this time, in the barracks outside the walls of the base, there were already prepared orderly soldiers and military dogs, and five civilian trucks were parked at the entrance of the base, although this kind of car is not bulletproof, but this kind of car is driving twice as fast in the desert as the usual vehicle in the desert.

There was already a person inside the barracks that Liu Di had heard of but had not seen, and Wu Peng was sitting in the barracks at this time waiting for Liu Di's order, but Liu Di obviously didn't know that Wu Peng had also arrived at the base.

"Brother Di, it has been determined that Lets City is being hit, are we going to help them!" Nightshade said, looking at a tablet.

"Packing up the equipment and bullets, Changno informs all the orderlies to be responsible for the safety and security of the base, and all the members of the Shadow Killing Team are ready to go," Liu Di said, looking at his watch.

Soon everyone got into the car, the ghost head and the black shadow were extremely excited, Liu Di, Tang Fan and the ghost shadow were in a car, Liu Di asked the two of them, "How did you come here?" ”

The ghost shadow was stunned for a moment and said, "We saw Wu Peng, he brought us here, and we teleported over directly." ”

Liu Di didn't continue to ask, after all, even if he asked clearly, he wouldn't understand how the base sent people over directly. The three vehicles followed closely together, following the direction indicated by the base along the way, and finally reached the outskirts of the city of Letus the next night, when the city of Letus was so quiet that no gunfire was heard.

"Why is it so quiet!" Nether asked, frowning.

"Nightshade, throw a drone and take a look."

When Nightshadow heard this, he hurriedly threw out a drone, and through the screen, he could see that the interception net on the edge of the city was not broken at all.

Liu Di thought for a moment and said, "Black Shadow, Ghost Head, and Thunder Shadow, the three of you go up there to have a look, and if there is no living person on it, return immediately." ”

"Yes!" After the three of them got out of the car, they ran towards each other's positions, and soon the voice of the ghost head came back from the earphones: "Report to Digo, the Border Department of Letus City is cleaning the battlefield, and we have arrived at the headquarters of the Border Department of Letus City." ”

After hearing the ghost's words, Liu Di said: "Drive the car in, we'll see you at the door of the headquarters." ”

Then Liu Di's car drove inside, and Liu Di saw that the soldiers were cleaning the bullet casings in the defensive places in front, and the bullet casings had covered the entire ground.

After seeing the ghost head, Remnant Yu knew that Liu Di was coming, and hurriedly stood at the door to greet Liu Di.

"Hello, Chief Liu." After seeing Liu Di get out of the car, Remnant Yu hurriedly stretched out his hand.

Then the two of them shook hands together, and Liu Di said to the remnant feather: "I rushed over after receiving the news of the ghost head, so you can tell me about the current situation here." ”

Remnant Yu looked at the people behind Liu Di and said questioningly, "You just take these people?" ”

Liu Di looked at him with a smile and said confidently: "Just a few of me are enough!" ”

"Come on."

Listening to Remnant Yu's tone, Liu Di knew that he didn't trust himself and the brothers he brought, so he came to the headquarters and said: "We have been fighting here for half a month, and there are about hundreds of thousands of mutants in the city, and about half of them have been solved by us, and our ammunition is seriously insufficient, but the interception net has not been damaged." ”

After thinking for a while, Liu Di looked at the sky outside that was not yet bright and said, "How long will it take for your logistics ammunition to arrive?" ”

"There are about 8 hours left, and mutants generally attack during the day, so the remaining ammunition must hold on for at least 3 hours."

"Nether, Dark, Ghost, you three go and set up the bombing point to ensure the last line of defense. Ghost Head, Thunder Shadow, and Night Shadow go to find the commanding heights, preferably a place with a wide field of vision, to ensure that you can kill a third-level mutant with one shot. Tang Fan quickly established communication equipment, and the principle was not to be interfered by mutants. Liu Di said to the people of the shadow killing team.

Liu Di did not rest in the headquarters but returned to the car, and after a few hours, he heard the voice of the ghost head in the headphones: "Commander, the mutant is out of the nest!" ”

"Okay, I see, everybody is in a fixed position." After Liu Di finished speaking, he took his gun and came to a high point, where the ghost head and the night shadow were eating beef jerky and talking.

"What's going on now?" Liu Di took a piece of beef jerky from the ghost head and asked.

"The mutants have started to come out, but they haven't attacked here yet, so I don't think there's anything wrong with it." The ghost head said as he ate.

Liu Di opened the cover on the scope and then looked into the city, there were already some first- and second-level mutants walking on the street in the city, and there was a data slot on the gun's scope, which could be used to determine how many levels of mutants it was aiming at at the center point.

"No, these mutants are cleaning up the battlefield."

"How is that possible?" The ghost head looked at the scope and said, "I haven't seen those mutants cleaning the battlefield just now." ”

Nightshade smiled and shook his head without speaking, as he was closing his eyes at this point. After a while, I heard a screaming sound coming from the city, and then Tang Fan's unclear voice came from the earphones, "Commander, the sound in the city has the effect of interference, and our signal has been interfered with!" ”

"Got it, you keep the signal as good as you can!"

Soon a huge fat man appeared in Liu Di's scope, looking at the display on the scope Liu Di said: "I'll go, such a big guy is actually a third-level mutant." ”

"Brother Di, a new third-level mutant, we haven't seen it before!" The ghost's voice spread throughout the Shadow Slayer team.

"I haven't seen this either, pay close attention to it, and if necessary, the sniper rifle will block it, I feel that the protection of this mutant should be very thick!"
