Zhang Hai and Lao Chen woke up from the coma in the next day, and Lin Fatzi asked him about his previous situation, he only remembered that he was attacked by iron ants that rushed up from the ground and hit his head, and he didn't know anything about the future.

Lin Fatzi and Zhang Hai rested in the ward for a few days under Xie Nan's care, and as soon as their physical strength recovered, they couldn't wait to take Zhang Hai back to the Military Museum to select the available firearms.

When he saw the guns on the second floor, he forgot all the iron ants, this is simply a paradise for military fans, from all kinds of old-fashioned equipment during World War II, to the new weapons in service now, Zhang Hai used all his learning, and collected all the guns they are currently capable of repairing, and soon a few people were loaded with a large cart, all kinds of pistols, rifles and even heavy machine guns.

After Lin Fatzi transported these guns back to the safety point, he instructed Zhang Hai and Professor Cao to organize the students of the School of Mechanical Engineering to concentrate on repairing these guns.

While instructing these students, Professor Cao also devoted himself to studying the remains of iron ants brought back by Lin Fatzi, and after his research, the secret of iron ant shells as hard as iron was solved.

It turns out that the shell of these ants is divided into two layers, the inner layer is no different from ordinary insects, but it is relatively thick, and on the surface of this shell, the iron ants have also evolved a thin layer of metal, this layer of metal hardness is very high, Professor Cao once used an electric drill and other tools can not drill through this shell, and finally had to use the electric oven in the laboratory to dissolve part of the outer layer of metal, this layer of metal is very thin but light and hard, and the remains brought back by Lin Fatzi can only be refined to the size of a coin.

Lin Fatzi understood what Professor Cao said, and his energy points were not enough to improve the level of star field science and technology ability, and the current level did not have a drawing suitable for using this metal, he knew that it was difficult to use the unknown metal on these iron ants in the short term, and instead focused on repairing the gun, but with the gun, the bullet became a problem, fortunately, Professor Cao and Zhang Hai knew a lot about weapons, and the materials and equipment needed for the manufacture of ammunition were quickly listed by the two. After reading it, Lin Fatzi handed it over to Xue Wei and the others, and asked them to collect it as soon as possible.

Professor Cao was in charge of gun restoration and other work, and the responsibility for logistics naturally fell to Hu Jing's head, Lin Ruoqing assisted her in organizing some women and elderly people to plant lettuce, shallots and peppers and other easy-to-survive seasonal crops in the vegetable fields around the playground, in addition to Lin Ruoqing spent her spare time studying this unknown magical fungus brought back from the ant nest, she first tried to use the medical microscope provided by Xue Shuyan to examine the structure of these fungi, Then he tested the toxicity of these fungi with some birds around the safety point, and was sure that the fungi were safe to eat, and finally with the help of everyone, he found an auditorium in the school building of the safety point to cultivate these fungi.

Zhang Hai and Professor Cao were busy repairing guns, and the work of repairing and renovating vehicles naturally fell on Chen Pingren, and almost every day, large and small minibuses or buses were driven back to the base by Xue Wei and others from outside, and soon 3 or 4 vehicles that could be used were selected by him and sent to the repair workshop for repair and transformation. In order to resist the zombies and even various mutated beasts on the road, they removed the glass of these vehicles and replaced them with barbed wire or iron fences, and even used the crash barriers and body steel plates of other vehicles to transform them into crash corners and install them in the front and rear of the vehicles. These large vehicles are already powerful, and with such ramming angles, they can directly rush up with one foot on the accelerator and crush them into pulp when they encounter a group of zombies, even if they are big guys like mutated beasts, they can also inflict fatal damage on them through violent impacts.

Lin Fatzi recuperated in the interval of physical strength, from time to time to go to the military museum, search for some waste shells and shells and other materials brought back as materials for the production of bullets, and at the same time check the recovery of the queen ant's injury, the queen ant gradually recovered her physical strength under the care of many worker ants, and the film that originally grew on the wound became an increasingly thick shell, and the mycelium outside gradually fell off with the recovery of the wound.

Lin Fatzi returned to the battlefield where they eliminated the old ant queen before, in order not to attract other beasts, at this time, the ant remains outside had been cleaned up by the worker ants under the instructions of the ant queen to the ground station that was originally used as a hatching room, when Lin Fatzi went down to check, he saw that the dense ant shells and stumps were stacked in the station, and when the time was ripe, when the metal on the surface of these ant shells he had the ability to recycle, the mountain of ant corpses in front of him would become a huge wealth, and the end times were like this, in times of despair, There is never a shortage of new hope.

Lin Fatzi began to think about the subway station in front of him, in the past, they were all transferred and searched for materials through the ground, if they can carry out daily activities through these underground networks, they only need to guard the subway station entrance to pass freely around the city, if so, it will greatly increase their search range and safety, but now he does not have so many people, and whether there are other groups of people like these iron ants or more terrifying creatures underground, he does not know now.

After all, the current queen ant was broken off her wings before the marriage flight, and she could not lay eggs because she did not complete the mating, and the current ant colony had no way to replenish every worker ant that was lost, and the previous soldier ants were also eliminated by themselves in the battle, and the original huge ant colony could only barely maintain the daily vigilance and food supply of the ant nest after the competition between the new and old ant queens, which was not enough to help them implement the plan to explore the subway network.

After Lin Fatzi thought about this, he returned to the safety point with the trophies, handed over the shells and shells made of copper and lead to Professor Cao and Zhang Hai's team, inquired about the progress of weapon repair and ammunition production, and was about to go back to his room to rest, but suddenly his sister Lin Ruoqing came running excitedly.

"Brother, come with me, I have made a new discovery!" Lin Fatzi heard his sister shouting at him from the corridor, and hurriedly turned his head to look at her, and at this time, the female prompt of the Eden system in his brain also sounded: "Check the target ability awakening, check it." ”

"I'm c, my sister has awakened too?!" Lin Fatzi looked at Lin Ruoqing who was running towards him in surprise, his face full of incredulity.
