• Lu Zhe found damp soil beneath some shrubs and discovered that the water in it was fresh, earning a Potential Point.
• Lu Zhe checked the Survival Manual, which advised filtering the water by wrapping the soil in a pure cotton sock and squeezing it.

• Ning Shu picked a branch of persimmons before Lu Zhe could finish explaining that they were too sour and astringent to eat yet.
• A scream and urgent whistle blasts came from camp, prompting Lu Zhe and Ning Shu to realize something was wrong.

Lu Zhe captured the cobra that had bitten Tang Xiaoguo and treated her wound with squeezed-out venom and wild persimmon. Tang Xiaoguo reported pain but no numbness or breathing trouble, and Lu Zhe believed the small venom dose had not put her life in immediate danger.

• Lu Zhe trapped the cobra in his pants and tied them into a sack.
• Tang Xiaoguo told Lu Zhe the snake had bitten her big toe after she kicked at it to protect Jiang Yao and Lin Qianqian.

• Tang Xiaoguo said her toe hurt but she had no numbness or trouble breathing, and Lu Zhe said her life should be safe.

After Tang Xiaoguo ate five wild persimmons to counter the snake venom, Lu Zhe prepared to make the snake the group’s dinner. He searched the shore for food and returned with a piece of kelp, while Tang Xiaoguo suffered the persimmons’ laxative effects.

• Tang Xiaoguo ate five wild persimmons to counter the snake toxins, despite their extreme astringency.
• Lu Zhe told Lin Qianqian, Ning Shu, and Tang Xiaoguo that the snake would be dinner if they found no other food, and said it needed to be cooked thoroughly.

• Lu Zhe found only tiny hermit crabs on the beach, then collected a large piece of kelp and earned a Potential Point for obtaining carbohydrates.
• Lu Zhe returned to camp with the kelp as Tang Xiaoguo finished her difficult trip to the toilet.

• Lu Zhe explained that he had recovered an important survival resource and showed them the seeds, but both girls recoiled in fright.

Lu Zhe searched for ways to secure food and fresh water while Tang Xiaoguo suffered from snake venom. He found a small pool of fresh water in the woods, but it was murky and needed filtering.

• Lu Zhe explained that seeds recovered from the girls’ waste could be used to grow fruit, but Ning Shu and Lin Qianqian refused to say what fruit they had eaten before boarding the plane.

• Lu Zhe found fish mint, gaining a Potential Point and discovering another possible source of food with some detoxifying properties.
• Lu Zhe found a small pool containing about two liters of fresh water and learned from the system manual that bra padding could filter its murky water.

Lu Zhe secretly used Jiang Yao’s bra to filter dirty pool water into fresh water, but Ning Shu, Lin Qianqian, and Tang Xiaoguo discovered it and accused him of stealing it. He defended his actions as necessary for survival, then insulted Tang Xiaoguo’s chest and left her furious.

• Lu Zhe took Jiang Yao’s bra while she slept and used its padding to filter dirty pool water into four bottles of fresh water.

• The girls confronted Lu Zhe with Jiang Yao’s bra, and he explained that he had used it to filter water.
• Lu Zhe argued that the girls would not have lent him a bra if he had asked, then mocked Tang Xiaoguo’s small chest and made her threaten to strangle him.

• Jiang Yao murmured Lu Zhe’s name while unconscious, and the others realized she was repeating their usual exchange about him washing his hands.
• Ning Shu and Lin Qianqian gave Jiang Yao water, and she woke up before vomiting after Tang Xiaoguo told her it came from a muddy puddle.
• Lu Zhe received a mission to help Jiang Yao overcome her germophobia and decided to shock her with the facts of their survival efforts.
• Lu Zhe told Jiang Yao that the group had used muddy water, seawater-soaked socks, and urine to save her, and that he had recently searched feces for seeds.
• Lu Zhe reminded Jiang Yao that her classmates had worked and risked themselves to keep her alive, then warned that she would have to eat anything she vomited back down.

Jiang Yao joined the survival team after Lu Zhe helped her adapt to the island, and the group learned that the tide had begun going out. They prepared to explore the beach as the evening low tide approached.

• Ning Shu admitted she had used Jiang Yao's bra to filter water, and Jiang Yao accepted the explanation without anger.
• Jiang Yao and Tang Xiaoguo discussed Lu Zhe's rescue of Tang Xiaoguo, while each privately felt competitive with the other.
• Lu Zhe observed that the tide had started going out at about 4:30 p.m. and estimated the coming high and low tides.
• Tang Xiaoguo suggested beachcombing for seafood, and Lin Qianqian explained that finding a king crab there was unlikely because they lived in cold, deep waters.

Lu Zhe tried to make a fire with a bow drill while the girls searched the shore for crabs and shells. As they returned, the girls spotted him working the drill and Ning Shu mistook what he was doing for something scandalous.

• Tang Xiaoguo insisted on joining the shore search despite her foot wound, so Lin Qianqian and the others took turns supporting her while Lu Zhe stayed behind.
