    Chen Xin does not plan to dismantle the equipment in his shelter, so to modify the vehicle, he must collect additional resources or make parts himself.

    Fortunately, he has a workbench, and he can process some parts of the materials needed to transform the vehicle himself. What he really needs to exchange and collect are mainly some raw materials and materials that are more cumbersome to process by himself and more convenient to collect through exchange.

    ¡°Chenxin, such as auto parts, cold-proof materials, and various steel materials needed for vehicle modification, must be obtained through exchange with Li Yulong and the SWAT team.

    But for other materials such as shock absorber springs, track parts, and water circulation devices, he can make them by himself. All he consumes is a small amount of survival points and raw materials.

    ¡°However, most of the raw materials Chen Xin reserved were prepared for the overall upgrade of the shelter that was originally planned. Most of them were building materials such as cement and steel bars, and the rest were mostly things like insulation boards.

    There are not many high-performance steels used to make shock-absorbing springs and track parts. There are only a few steel plates intended to strengthen the shelter building structure.

    "So we have to collect a batch of steel!" Looking at the list of materials, Chen Xin sighed helplessly.

    Although there is a system in place, even the simplest metal materials can be used as raw materials, and even non-metal materials can be used. However, considering the cost and investment issues, as well as subsequent use, Chen Xin feels that it is more appropriate to obtain a batch of steel materials.

    Fortunately, in addition to these parts that require metal materials to process, things like water circulation devices do not require a large amount of metal materials. Although the effect of using metal materials is better, other materials can also be used instead.

    So Chen Xin decided to use the existing materials on hand to make everything he could do. For what he couldn¡¯t do, he would also see if he could make some lower-level substitutes, and then use survival points to upgrade to make up for it.

    Although the function of the system upgrade is powerful, the consumption of survival points is not a small amount. Although he currently has close to five-digit survival points, according to the consumption listed on the list, if Chen Xin has no scruples  Using system functions to make these things would use up at least one-fifth of the survival points on his hand.

    So you should save if you can.

    Making a water circulation device is actually not too difficult and does not require too much material. The most critical thing is the recycling of waste water and sewage, as well as recycling after purification.

    There is no need to worry about the recycling of waste water and sewage. When the water circulation device is installed on the vehicle, the sewage recycling can be completed by using the pipes in the water area. The real focus is purification.

    Simple sewage purification treatment is not complicated. You only need to use activated carbon, sand and other materials to sediment and filter the sewage.

    But such a simple filtration effect is not good, and the chemical pollutants and heavy metal ions that may remain in the sewage will not be separated by such a simple filtration.

    Chen Xin purchased a portable filter necessary for survival in the wild, and also took it apart to study the structure inside.

    In addition to the basic sand and activated carbon filtration, the most important thing is the filter membrane. This filter membrane can effectively filter bacteria and other harmful substances in the water, making the original sewage return to a drinkable level.

    Chen Xin used this kind of portable water purification filter when he was playing wild survival in the past. When it is difficult to find a clean water source or when there is a lack of water boiling conditions and the water cannot be boiled for drinking, this kind of filter is really useful.  Convenient device for easy access to clean drinking water.

    This kind of filter is used as a water purification component of the water circulation device. It is not said that the material is overused, but it is more than enough.

    However, Chen Xin did not directly use his portable filter as a component to make a water circulation device, nor did he take it apart to obtain parts. Instead, he planned to make one himself.

    Saw a section of PVC pipe as the main body, and cut some more pipes as auxiliary materials. Use the system processing function to modify the structure and turn the pipes as auxiliary materials into end caps. The rest is to fill the main pipe with filter material.  .

    The filter membrane is made of a special material that Chen Xin doesn¡¯t have on hand. Although it¡¯s not impossible to make it with the help of system functions, Chen Xin doesn¡¯t need to go to that trouble.

    Since you want to borrow system functions, why not upgrade directly?

    After filling the sediment and carbon into the main body of the filter he made, Chen Xin compared the consumption required to make the filter membrane himself and directly upgrade the filter, and decisively chose to upgrade directly.

    After all, this is just aLittle thing, making the filter by yourself costs 10 survival points, but directly upgrading it only requires adding a few materials and only costs 15 survival points. In comparison, this survival point is still affordable.

    After upgrading the homemade filter to the same level as the purchased portable filter, Chen Xin used the filter as a water purification component and assembled it into the same homemade water circulation device.

    In this way, the water circulation device, which is one of the important components of vehicle modification, is completed.

    After checking the list, Chen Xin looked at the materials and parts listed on the list and thought about what he should do next.

    However, while he was thinking, his radio suddenly rang.

    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª

    At this time, outside Chen Xin¡¯s shelter, a police armored vehicle was parked in front of his house.

    "Chen Xin said he would open the door right away." In the car, a SWAT team member put down the walkie-talkie in his hand and reported to Li Tou and a man sitting next to him who was not wearing a police uniform and looked like an official.

    Both of them nodded and said nothing more.

    Previous Operations Although Li Tou's team was not only injured in the hospital due to previous operations, but also several other team members were also injured and treated in the hospital. However, even if there is a lack of manpower, under the current situation where the whole city is mobilizing for a large-scale platoon,  , they were still sent out to work with the staff of the joint investigation team to conduct a survey and arrangement of unofficial shelters.

    "The person living here is a member of the public who cooperates with our SWAT team. He mainly provides our SWAT team with fresh vegetables in exchange for some survival supplies. We have come to investigate before and there is no suspicion." Li Tou turned to him.  A man who looked like an official explained the situation, but he was obviously trying to put in a good word for Chen Xin to avoid the possibility of Chen Xin being suspected.

    "The work of the comrades of the municipal bureau is of course trustworthy. However, the joint investigation team decided to conduct a second investigation. It is safer to conduct another inspection." The official-looking man nodded slightly and did not make any obvious reaction to Li Tou's words.  .

    But looking at his expression, Li Tou also knew that he had listened to his words.  (Remember the website address: www.hlnovel.com
