Li Chen, Zheng Kai, Sha Yi, Bai Lu, Zhang Zhenyuan, Xie Yilin, Chen Xiaoting, and Cheng Lei traveled to Pu'er, the "World's Tea Source," to sip tea around a fire, listen to stories of horse caravans, and hike in the rainforest to experience the natural atmosphere. Before embarking on a team-building trip, a game of "obeying the minority" surprised everyone. Before setting off on the ancient trail, the members experienced the caravan's pre-trip ritual—throwing a shoe to ask for directions. Each member took turns throwing straw sandals onto a gourd array. To enjoy a more diverse dinner of horse caravan cuisine, a game of "increasingly large word formation" immediately began, with the members racking their brains and brainstorming abstract ideas. The Pu'er trip was split into two groups. The group with the most "golden leaves" flew to Dali early the next day to begin their "special forces" journey.

Li Chen, Zheng Kai, Sha Yi, Bai Lu, Zhang Zhenyuan, Xie Yilin, Shen Xiaoting, Cheng Lei, and Gao Hanyu continued their journey through Pu'er and Dali, experiencing the unique local customs and cultures of each region. Before embarking on a new day of travel, the Pu'er team officially began their coffee "competition." After warming up their sense of smell, the taste and brainpower followed. Weishan Ancient City, located at the heart of the Ancient Tea-Horse Road, has been a key stop on the route since the Tang Dynasty. Its rich local history and culture contribute to its unique charm. Here, a puzzle-solving challenge begins, with Zhang Zhenyuan, Cheng Lei, and Gao Hanyu tasked with solving a puzzle from eight clues.

Li Chen, Zheng Kai, Sha Yi, Bai Lu, Zhang Zhenyuan, Meng Ziyi, Li Yunrui, Gao Hanyu, and Zhai Zilu traveled to Dali for a special travel photography project. Divided into two teams, the "Haidong Line" and the "Haixi Line," they traveled to Bai Lu's signature check-in spots, capturing the beauty and joy with their cameras. To earn priority selection for tie-dye apparel, the "Tea-Containing Message" challenge began. The two teams searched for "deer" along Erhai Lake, visiting Guyue Jibai Cliff Seaview Villa and Longkan Wharf, respectively. Observing the rippling lake and swirling clouds, they felt a juxtaposition of poetry and everyday life, as if centuries had settled in. In a leisurely, slow-paced setting, a "snowball tongue twister" game, designed to test speaking speed, began.

Li Chen, Zheng Kai, Sha Yi, Bai Lu, Zhang Zhenyuan, Meng Ziyi, Li Yunrui, Zhai Zilu, Gao Hanyu, and Yu Yang drove from Dali to Lijiang, enjoying the magnificent natural scenery and experiencing the ancient Dongba culture of the Naxi people. Picturesque Dali is not only renowned for its Cangshan Mountain and Erhai Lake, but also for its diverse and delicious cuisine, attracting countless diners. The Dali photoshoot concluded, and to sample the local snack, Erkuai, before departing, a special block-laying game began. The members were divided into three groups, each wearing a pacifier, earphones, and an eye mask, and working together to arrange blocks into designated shapes.

Li Chen, Zheng Kai, Sha Yi, Bai Lu, Zhang Zhenyuan, Meng Ziyi, Li Yunrui, and Yu Yang witnessed the golden glow of the sun at the foot of Jade Dragon Snow Mountain and embarked on a unique hike through Tiger Leaping Gorge, experiencing the wonders of nature together. To capture this good fortune, the members, overcome by the cold and sleepiness, sat in rows, tea in hand, and pre-emptively embraced "nursing home mode." Before setting off for their first "dangerous" adventure, a "future travel diary" broke the tranquility, detailing the members' journeys: mountain hiking, carrying water, and eating insects.

Li Chen, Zheng Kai, Sha Yi, Bai Lu, and Zhang Zhenyuan joined Zhou Shen and Song Yuqi for two special "rescue" missions in Lijiang and Shangri-La, experiencing the unique Tibetan culture amidst the tranquility of Tibetan incense. Before departure, the members received a distress message: Song Yuqi was "trapped" at the Dongba Adventure Center. Faced with a 90-meter-long suspension bridge, the group bravely launched a joint rescue plan. Upon arriving at the Napahai Sky B&B, Zhou Shen's cabin was locked, and to obtain the code, they embarked on a "nose typing" challenge.

Li Chen, Zheng Kai, Sha Yi, Bai Lu, Zhou Shen, Song Yuqi, and Zhang Zhenyuan continued their journey through Shangri-La, carrying on with their "Bill-Paying Campaign" and engaging in a race against time. They explored historical sites within a tight schedule, demonstrating unity and hard work through their actions. Amidst the lively atmosphere of the banquet, the bill-paying campaign entered its most intense phase. To secure the ancient city's unique souvenirs, the "Brotherhood" quickly split into four groups and embarked on a relay-style hidden object challenge.

Li Chen, Zheng Kai, Sha Yi, Bai Lu, Zhou Shen, Song Yuqi, and Zhang Zhenyuan climbed to the summit of Shika Snow Mountain, searching for the last remaining ancient bell and sharing their deepest thoughts, bringing their team-building trip to a successful conclusion. The "Brotherhood" took the cable car to the Shika Snow Mountain mid-station, where the familiar shoe-throwing challenge began, symbolizing the journey's beginning and end. Reaching the summit marked the end of the journey, and the "Brotherhood" reluctantly faced the final challenge. Donning face-to-face glasses, they concluded their journey with words of "sorry," "thank you," and "I love you," sharing the unspoken truths of their journey.
