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.
