After buying the mobile house, Li Yao sat in the living room with her laptop, poured herself a glass of honey water, and began to formally plan how to stockpile supplies.

First, there are the major categories of clothing, food, housing, and transportation. Then there are energy sources such as fuel oil, coal, gasoline, and electricity. Finally, there are protective products made of high-tech materials.

Li Yao then searched online for a list of essential items for post-apocalyptic survival enthusiasts.

This includes the Wiseman Survival Manual and the US Army Survival Manual, as mentioned by netizens, as well as videos on wilderness survival. It also includes electronic and paper copies of the World Encyclopedia of Flora and Fauna, the Encyclopedia of Traditional Chinese Medicine, world maps, maps of China, and maps of various provinces, along with various skill books, including materials on carpentry, electrical work, textiles, and more.

Once we return to a society without industry, the production and manufacturing techniques of intangible cultural heritage can still play a significant role, naturally including a lot of similar materials and videos.

After the apocalypse, order collapsed, plants mutated, cities became wastelands, and everything Li Yao prepared was based on a 150-year timeframe.

Time is long, and even with systems and space, one should try to learn as many survival skills as possible to adapt to changes in the social environment and also to pass the time.

Because Li Yao has decided to be a lone wolf, it would be best if she could have a pet. Her secret is too big to be shared with others, and besides, the system is developed for space applications.

Li Yao felt that time travel was also a form of spatial energy application. Thinking of this, Li Yao asked the system...

[6384, Is time travel also an application of spatial energy? Can you construct a spacetime anchor point to take me through time?]

The system replied, "[Ding, time travel is a combined application of time and space. The system cannot travel at present. The host needs to work hard to reach level 10 so that system 6834 has the energy to connect with the time application system. Only then can the host purchase time application skills and combine them with space skills to travel to other time and space.]"

Li Yao thought to herself, "It really is possible to travel through time." Then she asked, "[6834, can stockpiling resources and developing the spirit spring space also increase application skill points?]"

The system replied, "[Ding, yes, host. As long as you use spatial power, you can increase your skill application points.]"

Upon hearing this, Li Yao instantly wanted to go abroad to exploit loopholes. While she could teleport, maps were a problem. So, Li Yao asked the system again: "[6834, can you connect to the Earth's network and satellites? Can you hack into other people's surveillance systems in real time?]"

[Ding, 6834 is acceptable, host.] Li Yao thought to herself, "That makes sense. If you think of the system as an artificial intelligence, it's invincible when connected to the internet." So, Li Yao asked the system if she could download data. She wanted the system to save all the data that could be stored on Blue Star so that if she left in the future, she could leave this data for those who needed it. The system readily agreed.

Li Yao purchased 50 computers from the same city and had them delivered to her door. She also ordered 1,000 15TB hard drives from the same city so that the system could connect to the internet to download data.

She had the system download all the existing humanities and science data first, and then ordered 10 computers, 10 laptops, 20 of the latest mobile phones, and 50 tablets online. She also placed orders for a total of 50,000 hard drives of the largest capacity from different outlets. The delivery address was an office building under Li Yao's name that was not rented out. Li Yao decided to use this place as a warehouse in China for the first six months.

Li Yao called the internet service provider to install internet in the building, paid 5,000 yuan for electricity, and ordered 5,000 sockets. Everything was ready, and she could start downloading documents as soon as the goods arrived.

Li Yao summoned the system: "[6834, construct a door. This door allows for instantaneous teleportation. The other side of the door is where I want to go.]"

The system replied: [Ding, a teleportation portal has been constructed based on the host's thoughts and language.]

Li Yao recalled a TV series she had watched before, featuring a spatial teleportation skill that allowed her to traverse space as far as she could see. Once activated, Li Yao could appear anywhere on the target mission with a single punch, regardless of distance. So, she opened her phone, found the TV series, and had the system create a similar skill, naming it "Spatial Teleportation."
