Su Yao prepared to head to the villa. The female protagonist mentally stored everything in her current house into her spatial dimension. Suddenly, she felt dizzy, but after a while, she felt better. She then discovered that her spatial dimension had upgraded. She noticed that the jade artifact she had previously stored away was missing. Did the spatial upgrade require the jade artifact? She shook her slightly dizzy head, quickly overcoming her discomfort with the joy of the upgrade. She didn't have time to investigate whether the jade artifact's disappearance was directly related to the spatial upgrade; her immediate priority was to reach the villa and build a safe house.

She arrived at the villa, a luxurious suburban estate surrounded by open space and greenery. The protagonist first used her mind to retrieve tools from her spatial storage, including building materials and defensive items. She began by reinforcing the villa's exterior walls, taking out special metal plates—lightweight yet extremely strong—and covering them with the existing facade. Each plate was secured with special rivets to ensure there were no gaps.

Next, the windows. The protagonist installed multi-layered bulletproof glass with reinforcing fibers sandwiched between the panes, which could not only withstand bullet damage but also prevent impacts from zombies. Around the edges of the glass, she used a special sealant that hardens upon impact, further enhancing the window's stability.

For the main entrance, the female protagonist chose a heavy-duty security door. The interior of the door was filled with fire-resistant and impact-resistant materials, and the surface had a special coating to prevent corrosion and scratches. The lock was a high-tech three-in-one design combining fingerprint, password, and mechanical key, which could only be opened by the female protagonist and her trusted family members.

Inside the villa, the female protagonist begins to create a safe living area. She sets up an emergency shelter in the basement, its walls reinforced with thick concrete and steel plates to withstand major disasters such as earthquakes and explosions. The shelter has an independent air circulation system equipped with a high-efficiency air purifier and oxygen supply device, ensuring fresh air inside even when the outside air is polluted.

The woman also installed multiple surveillance cameras inside the villa. These cameras are equipped with night vision and motion capture capabilities, allowing for comprehensive monitoring of the area surrounding the villa. The cameras are connected to a central control system installed in a secluded room within the villa. The woman can use this system to view the surveillance footage at any time, and the system will automatically issue an alarm in case of any abnormality.

Regarding food storage, the female protagonist utilized the resources within the space to set up several large storage rooms in the villa. These storage rooms had dedicated shelves where she categorized rice, flour, cooking oil, canned goods, and other items according to type and expiration date. Additionally, she installed multiple large refrigerators and freezers in the villa's kitchen to store meat, seafood, and other foods requiring refrigeration.

To ensure a stable water supply, the woman dug a deep well in the villa's yard and installed an advanced pumping and purification system. This system extracts groundwater and performs multiple filtration and disinfection processes to bring it up to drinking water standards. In addition, she installed several water storage tanks within the villa to store backup water.

Regarding weapons and defensive equipment, the female protagonist stored a large quantity of firearms, ammunition, knives, and protective vests in a secret room of the villa. These weapons were meticulously maintained to ensure they could be used properly in critical moments. She also set up simple traps throughout the villa, such as pressure-sensitive mechanisms hidden under carpets and tripwires in the stairwells; these traps could deliver a surprise attack if zombies or other enemies invaded.

After careful renovation, the villa was transformed into an incredibly sturdy safe house. Looking at her creation, the female protagonist felt a great sense of accomplishment and gained more confidence in her future life in the apocalypse.
