The only problem in this area is that there may be residual zombies, and it will take some time to clean them up, but Lin Fatzi has zombie dogs and werewolves, as long as there are no mutated zombies among these zombies, they will naturally not pose a threat to them, and how to deal with this kind of mutant zombies, Lin Fatzi needs to ask Zhang Hai, who was too scared to speak by himself just now.

"The new zombie we encountered at the army security point before, it is stronger than other zombies, rifle bullets can't cause effective damage to it, and it can also manipulate other zombies around it through psychic abilities, is there a way to make some more powerful weapons to deal with it?" Lin Fatzi said, and glanced at Xia Siying beside him, after all, Xia Lao Jingjun used his own glorious bullet to blow it up, and he mentioned this monster again, I'm afraid it will make her a little sad.

But by this time she seemed to regain her emotions, stopped crying, and listened attentively to their plans.

"A more powerful weapon?" Zhang Hai heard Lin Fatzi ask himself, and said to himself: "If you want to say that the weapon that can be made now is more powerful than a rifle, it is the Molotov cocktail, which can be made with gasoline and beer bottles, but it is not convenient to carry, and the effective attack distance is relatively close." ”

"This weapon is only suitable for self-protection when we encounter a group of zombies at a safe point, and it is useless to encounter the mutant zombies who are more agile than me before." Lin Fatzi directly denied Zhang Hai's idea.

"I have an idea about heavy weapons." Professor Cao, who had been silent, suddenly spoke at this time. Everyone looked at him, and Professor Cao was highly respected in the whole safety point, and if it was his suggestion, it must be very valuable for reference.

"With our current capabilities, there is no problem at all in producing black powder, and it should not be difficult if we can find ancient smoothbore guns from military museums, and with laboratory equipment, produce some shells from the collected lead and copper." Professor Cao said as he asked for Lin Fatzi's opinion.

When Lin Fatzi heard this, his heart was suddenly happy, he had seen a lot of movies about ancient wars, the kind of ancient artillery cast of pure iron in the face of the enemy's cavalry charge, a single shot can blow up a large area, if there is such a weapon, not to mention the kind of mutant zombies encountered before, it is a beast the size of an elephant, and it can be blown apart with a single shot.

"I'll go to the Military Museum tomorrow and bring those cannons back." Lin Fatzi said: "When these artillery pieces are repaired, we will be ready to set off at any time to investigate the situation of the new site in the security zone." ”

Everyone naturally had no objections, and at the end of the brief meeting, Xie Nan briefly treated their respective wounds for Lin Fatzi and the others, and everyone disbanded and rested.

Soon the night passed, Lin Fatzi called Hu Bing and Zhang Hai in the early morning, and took a few of the strongest werewolves, drove the big truck when they rescued Han Lei, and went to the military museum to collect cannons.

Several people searched a large circle in the museum, although there are many kinds of artillery used in the museum exhibition, but most of them are old, lack of maintenance, the cannon body is rusty, and the barrel of the cannon is uneven.

Lin Fatzi took the opportunity to find the artillery this time, and returned to the ant nest to check the situation, the new ant queen he controlled before was injured in the life-and-death battle with the old ant queen, and now he has fully recovered, and when he saw Lin Fatzi, he actually showed some joy that ordinary people could not detect.

Lin Fatzi thought about it, if these iron ants can be used to fight, it is really an extremely powerful force, but the new ant queen now has no breeding ability at all, and the ant colony is not easy to transfer in batches, he remembered the plan he had thought about before to use the subway to build an underground transportation network, but the last war caused this iron ant colony to suffer heavy losses, and the number of worker ants was barely enough to maintain the normal survival of the entire ant colony.

It seems that the best way to restore the entire colony is to help the new queen find a suitable male as soon as possible, and his plan will continue to be shelved.

At this time, the survivors brought by Han Lei and Xia Siying in the safety point had already seen the werewolves and zombie dogs outside the safety point, and they also learned about the situation of these zombie dogs and werewolves from the original survivors of the base, and only then did they know that Lin Fatzi had such a strong strength to control these monsters.

Lin Fatzi knew that he couldn't hide these from them sooner or later, and someone else explained for him, so he naturally saved himself from wasting energy, so he drove the big truck directly to the repair workshop and discussed with Zhang Hai and Chen Bing how to repair these bulky cannons.

"This thing is big and heavy, is there a way we can modify it a little bit to make this cannon more flexible when used in the future? After all, this thing has to go with us to the new safe zone to destroy the zombies, and I can't let the werewolves carry it for 200 kilometers. "When Lin Fatzi helped the werewolves carry these two cannons just now, he personally felt the weight of these two cannons, and in terms of his strengthened physical fitness, he was almost broken at the waist, if these two iron cannons have no maneuverability, they are no different from two scrap irons.

"Brother Lin, the pickup truck you drove away before weighed less than 1 ton, and these two guys each had to weigh more than two tons, so I think we can fix them on a small truck, so that it is easy to move and can be adjusted at any time." Chen Bing had a whim.

As soon as Lin Fatzi heard this, these cannons themselves have cannon lugs next to them, which can be fixed in the stone trough on the ground or on the wooden cart. Now they fasten it to a wagon, and it's a simple version of a mobile gun.

So he immediately arranged for Hu Bing and Xue Wei to go out to search for suitable trucks, which were almost everywhere before the end of the world, and soon the two found a suitable one in a nearby neighborhood and drove back, while Zhang Hai and Chen Bing happily modified the two cannons with the assistance of werewolves.

Lin Fatzi checked the progress of various preparations for their next trip, Han Lei learned that Professor Cao was going to produce artillery shells, and took the initiative to ask his workers and himself to join Professor Cao's team, with these professional and skilled workers to join, Professor Cao's work was very smooth, several people not only helped Professor Cao use laboratory equipment to produce a mold for making solid shells, but also used their professional technology to improve the original equipment for producing rifle bullets, so that the output of rifle bullets from less than 50 rounds per day, It has become possible to produce up to 200 rounds per day.

Lin Fatzi even showed Han Lei the metal of the iron ant shell that Professor Cao had smelted before, and Han Lei looked at this coin-sized piece of black metal left and right, whether it was light weight or hardness far beyond steel, he was amazed.

"It's a pity that the amount of this metal is too scarce, otherwise it would be nice to use this metal to make a few knives, or make bullets." Lin Fatzi felt a little sorry when he thought that it was so difficult to refine these metals, and at the same time, his iron ant colony could not be regenerated.

"If you want to talk about war knives, it's not that you can't make them." Han Lei's words suddenly attracted Lin Fatzi's attention: "I don't know if you know the practice of Japanese katana, in fact, they just use the hardest and rare metals to make blades, and the blade is still made of ordinary metal materials, if I can get more of these metals, maybe I can forge a good katana." ”

When Fat Lin heard him say this, he was very happy in his heart, and thought that when he had enough electricity, he must make use of the remains of those iron ants.

Soon the first few shells were produced, and Zhang Hai and Chen Bing's transformation work also came to an end, and finally the day came to test fire the artillery.
