Starting from Robinson Crusoe

Paul’s needle and thread kit contains three large spools of thread, with only two needles, perfectly complementing the ninja’s kit.

As for the water purification tablets, they’re the common chlorine dioxide disinfectant effervescent tablets, which Chen Zhou often used during outdoor activities.

These purification tablets only need to be thrown into the container and mixed well to achieve disinfection and sterilization, usually one tablet can purify 1 liter of water, but after being added to the water, it takes at least 30 minutes before the water can be used.

And the ninja’s bottle of purification tablets has a smaller capacity, with only 100 tablets, and all the writing on it is in Japanese.

Chen Zhou knows a little Japanese, can understand and speak but can’t read or write, so looking at the explanation with Japanese mixed in with Chinese, he can only guess that this bottle of purification tablet has a much higher chlorine dioxide content than ordinary ones, and can be called "concentrated powerful purification tablets."

However, compared to using purification tablets to make safe drinking water, boiling is still more cost-effective, considering boiling requires no consumables.

After finding the needle and thread kit and purification tablets, Chen Zhou meticulously searched the entire ninja suit but found no other items.

At this point, Chen Zhou could basically confirm that these seven items were all the survival tools the Japanese ninja acquired, so he started checking the American soldier’s combat uniform.

...

Seeing the Japanese ninja carrying so many items, Chen Zhou thought the American soldier’s "treasures" would be equally abundant, but after a thorough search, he only found a pair of gloves and a magnesium rod.

These two things plus the hand axe and the camp pot totaled only four items, even fewer than Paul’s survival tools.

Wondering why the survival tools issued by the Time Travel Administration Bureau were so random, Paul, upon leaving the campfire and entering the semi-permanent shelter, called out loudly.

When Chen Zhou entered the shelter, he discovered that the last survival tool of the American soldier had been used to construct the shelter—

Several sections of cut paracord tightly bound the wooden beams of the shelter’s roof, firmly securing the entire shelter, while half a bundle about 18 meters long was left on the ground, apparently the remainder after tying the beams.

"No wonder the flood didn’t scare them off. They cut open half a bundle of paracord and devoted it to building the shelter; these two guys really went all out.

Clearly, they can’t part with this ’feng shui treasure land’!"

Putting away the paracord, and looking at the multiple sections of paracord overhead, Chen Zhou felt a bit distressed.

A full bundle of paracord could help Paul climb cliffs or scale towering trees, but the cut-up paracord was much less useful.

Damn those Japanese and American soldiers for wasting resources, Chen Zhou initially wanted to untie the paracord, but after glancing at the spacious and tidy interior of the semi-permanent shelter, he decided not to.

...

"Let’s rest here tonight.

Once my clothes are dry, we should go fetch the small serrated tiger cub and also cut some beaver meat and fat,

Today’s cooler temperature means that without a swarm of scavengers fighting over it, the meat should still be fresh.

Let’s spend the night here, and set out tomorrow morning." After making arrangements, Chen Zhou added.

"We also need to quickly find a suitable place to build a shelter.

As autumn sets in, temperatures drop rapidly, and this area is so vast we can’t always rely on luck to encounter other challengers.

Most of the time, we’ll be contending with beasts, the environment, especially the rapidly falling temperatures.

In such situations, having a secure and solid home becomes crucial."
