With the normal production of canned food in the safety zone, Lin Fatzi and they tasted the canned products produced by themselves for the first time, even so they did not dare to let go of eating, after all, their food supply is still abundant, but the packaging used to produce canned food is not rich, these canned boxes need to be processed and produced with specially treated metal, although there is corresponding equipment in the cannery, but these metal materials they have no way to get supplies.

Lin Fatzi opened a can of freshly produced cans for everyone to taste, and everyone was full of praise for Hu Jing's recipe, so these freshly produced cans were immediately loaded and transported back to the warehouse in the area where the geothermal power plant is located for storage, in case of food shortages in winter.

Some of the fruits and vegetables planted by Lin Ruoqing can also be ripe and picked, so that the supply of food and vegetables in the safe area has been greatly alleviated, plus every day the lizards catch a large number of sea fish under the arrangement of Lin Fatzi, so soon the cold storage of the entire canning factory was filled with these sea fish.

Lin Fatzi and they calculated all the food reserves now, enough for them to support at least 2 or 3 months, plus those potatoes in Lin Ruoqing's field, which can be harvested in a few months, it should not be a problem for all the residents in the safe area to survive this winter, as long as the sea water thaws, they can resume fishing again, so the problem of food seems to have been temporarily solved now.

Winters in City B are cold, so before the end of the world, the peninsula where the safe zone is located will have heating as soon as November begins. Dr. Gu and Professor Cao had long considered everyone's needs for the winter, so as soon as the mutant plague passed, they began to prepare for the repair of the heating equipment in the safe zone.

Previously, the entire peninsula where the geothermal power plant site was located was heated with cooling water from the geothermal power plant, so they only needed to go through a simple overhaul to get heating back on.

The situation of water supply is more complicated, after the outbreak of the end times, most of the water sources have been contaminated by the end of the world virus, and there will be some hidden dangers in all direct references, but fortunately they have experts like Dr. Gu, and he quickly determined a plan with his assistant Lu Yuan, that is, to use the cooling water after power generation for drinking water supply.

The cooling water itself is distilled water and does not contain magazines, so there is no need to worry about the contamination of the apocalyptic virus, and it is heated and boiled by geothermal heat before cooling, and even if there is a residual virus, it is killed by high temperature.

It will take at least a month or two to renovate the entire water system, but according to their plan, the water supply system in the entire security zone can be restored before winter hits.

Lin Fatzi knew that Dr. Gu and Professor Cao were in charge of this work, and he didn't have to worry about it at all, so he ended up having a good time, and finally there was good news from Han Lei's side, after nearly two weeks of polishing, the first katana made of iron ant shell metal has been completely made.

After Lin Fatzi learned the good news, he took the Zhang sisters to the shipyard together, and Han Lei was already waiting for them at the factory gate with the treasure knife that had condensed their hard work for several days.

"You guys can count it, we have been forging and polishing this knife day and night, the metal on these iron ants is simply too powerful, the melting temperature is extremely high, and the toughness is good, so it is difficult to forge, plus the metal surface is very hard, we spent more than a week just polishing it, and now this knife is finally made, which of you will be the first to try?" Han Lei handed over the treasure knife he had worked so hard to make, and when Lin Fatzi saw this, he hurriedly took it with both hands.

As soon as this knife fell into Lin Fatty's hand, he felt the huge difference between this knife and other weapons. Previously, they had been using those ancient swords or daggers collected from military museums as weapons, and those weapons were also the masterpieces of ancient craftsmen, otherwise they would not have been preserved to be so sharp today.

But after all, due to the limitations of materials and technology, no matter how powerful the wisdom of the ancients was, there was no way to produce a weapon like the one in the hands of Lin Fatzi now. This sword, made of iron ant metal, is the size of a Japanese samurai sword, but the blade is unusually light. After Lin Fatzi felt the weight of the blade, he was amazed, but after all, the purpose of creating this knife was to allow Zhang Shuya to give full play to her ability. So Lin Fatzi just sighed, and immediately handed it over to Zhang Shuya's hands.

Zhang Shuya is a master of using melee cold weapons, as soon as she took the knife handed over by Lin Fatzi, she immediately felt that the weight of this knife was different, first of all, the weight, she was a weak girl, holding it in her hand, she didn't feel that this knife was very heavy at all, even if it was a hand, she could swing it freely. Then the balance of this knife was almost perfect, she couldn't wait to pull this knife out of the scabbard, and as soon as she pulled it out, the cold light reflected by this knife surprised Lin Fatzi and a few people.

Han Lei saw their surprised faces, and smiled proudly: "How about it, didn't you expect it?" This is my masterpiece. ”

Lin Fatzi and the Zhang sisters looked at the long knife in front of them that even the blade was pitch black, and they really didn't know what to say, Zhang Shuya felt the cold air emitted by the blade of this knife, and suddenly had an urge to find a target to try this knife.

Han Lei seemed to see Zhang Shuya's thoughts, and hurriedly said: "I have prepared a stake for you to experiment with this knife, you come with me." ”

After speaking, a few people followed Han Lei to the courtyard of the shipyard, and then saw that in a corner of the courtyard wall, there were three wooden stakes of different thicknesses neatly erected, it seemed that they should have just been erected here, even the thinnest one was the thickness of an arm, and the thick one was as thick as a human thigh.

Zhang Shuya saw that the stake for the test knife had been erected, so she naturally couldn't hold back her excitement, and was the first to rush forward, and before Han Lei instructed her, she pulled out the knife from the sheath, and then used this pitch-black long knife to cut at the thinnest stake.

The three people behind her saw a black light flash from her hand, and the arm-thick stake was broken in response, Lin Fatzi and they didn't react, Zhang Shuya's figure changed, just now she felt the sharpness of the knife, and her heart was overjoyed, and the knife was not completely withdrawn before she turned around and slashed towards the thickest stake.

Her speed was so fast that the others didn't see what was going on, and another stake was cut into two straight and neat pieces. Lin Fatzi and the others were amazed by the sharpness of this knife, but Zhang Shuya didn't seem to have the slightest intention of stopping, and turned his hand and split the wooden stake in the middle directly from top to bottom.
