The area was deserted, so Xu Lin took out a moisture-proof mat and had a picnic right outside the cave.

After finishing their meal, Xu Lin cleared away the plates, took out snacks and fruit, and lay down on the moisture-proof mat with Zhou Pin.

The mountain was not as affected by natural disasters as the city. Lying on the ground, I felt like I had returned to the pre-apocalyptic world.

Xu Lin lay on Zhou Pin's lap, while Zhou Pin held a map in one hand and stuffed grapes into Xu Lin's mouth with the other.

After resting for half an hour and finishing their fruit and snacks, the two got up and continued collecting supplies.

By evening, all the trees around the cave had been harvested, and Shuke and Beta returned, both covered in mud. Xu Lin dragged them into the space to take a bath, while Zhou Pin went to cook.

Dinner was rather light: dry-pot cabbage, stir-fried broccoli, cold tripe salad, and tomato and egg soup. The dogs went to their own room to eat after their baths; it was all imported food, they didn't even look at the local specialties.

“I looked at the map, and the place where I put my supplies is just over this hill.”

"Is there another cave on the other side of this mountain?"

"There are caves and dark rooms."

“I think the cave Brother Long found is quite deep. Do you think there’s a possibility…”

“That is indeed a possibility,” Zhou Pin said after a moment’s thought.

Perhaps Xu Lin's words inspired Zhou Pin. He didn't even bother to eat and took a detailed map from Xu Lin, spreading it out on the coffee table in the living room to start studying it.

“The mountain we are in now belongs to the Daxing Mountain Range. I also stored supplies in Anshan, which is part of the Daxing Mountain Range. Before, I was looking at a map of the entire Inner Mongolia Province. Now, I’m looking at a map of the Daxing Mountain Range separately. If nothing unexpected happens, the cave where Brother Long and I stored our supplies is the same one, but the middle part is blocked.” Zhou Pin said to Xu Lin, pointing to the map on the table.

"That's great! There are explosive devices in the space, so we can break through the middle, which will save a lot of time." Xu Lin's excitement was palpable.

The two returned to the dining table and quickly ate their meal. Zhou Pin then sat on the living room floor, studying a map of the Daxing Mountain range to see if there was a place where they could collect supplies.

Xu Lin wasn't good with maps, so she took out a book about the specialties of the Daxing Mountain range and started reading.

"One of the specialties of the Daxingshan Mountains is potatoes. Potatoes from the Daxingshan Mountains are characterized by high yield, excellent quality, and good traits."

"Uliginosum, also known as persimmon, is a wild deciduous shrub belonging to the Rhododendron genus. It grows in the primeval forests of the Daxingshan Mountains north of 52 degrees north latitude. Its ripe fruit is black and purple."

"The Daxing Mountain Range has three treasures: the old three treasures are ginseng, sable fur, and Ula grass; the new three treasures are ginseng, sable fur, and deer antler."

Xu Lin quickly jotted down the descriptions in the book and took photos of the actual items to save them.

Xu Lin woke up before dawn the next day. The previous day's work hadn't exhausted her; on the contrary, she was full of energy.

The two arrived at the deepest part of the cave. Xu Lin took out the explosive device, gas masks, and protective suits. The two changed into the protective suits, and Zhou Pin secured the explosive device.

To prevent the entire mountain from collapsing, multiple blasts in small batches are needed. Fortunately, Zhou Pin had read some related books before and knew a little about it.

The two emerged from the cave, found a safe spot, put on gas masks, and lay prone on the ground, preparing to detonate the device.

With a loud "bang," the earth shook, and the sun slowly peeked out from the distant mountaintop, heralding the start of a new day, another day full of hope!
