Background / History

Cai Xiaodong becomes acquainted with Li Yi during morning training in the Special Selection Class. He quickly takes on an informal mentor role, explaining how ancient civilization ruins can upgrade Divine Mechs by supplying surplus divinity, and why Li Yi's Pluto Mech may have originally been an A-class Divine Mech 31.

He continues helping Li Yi understand the class's internal systems, including Divine Radiation combinations and the advantages and risks of mixing different radiation types 39 40. Li Yi later makes a deal with him to investigate Zhang Xuqiang and other top students, using Cai's ability to gather information 40.

Cai becomes a target of Zhang Xuqiang's faction after refusing to exchange Divinity Radiation time with Qian Shengyue. Zhang Xuqiang plans to have Qian seriously injure him in a real match to force him out of the Special Selection Class, but Cai refuses to yield 44.

During the Tian Shu Ruins explorations, Cai joins Li Yi's team and follows his command in battles against guardian mechs and divine creatures 59 67. He later participates in dismantling a Divinity Flash Grenade launch device, using Super Shockwave cutting and internal sabotage methods before being the first eliminated by the detonation 79.

In the real ruin operation, Cai advances his Divine Mech at the Ascension Pool and later helps Li Yi and Zuo Ying secure the Gourd Men's laboratory 115 116.

Personality

Cai is open, talkative, and useful as a source of practical information. He shares knowledge without much prompting and helps Li Yi quickly understand opportunities that ordinary newcomers might miss 31 39.

He is also stubborn when pressured. Even when targeted by Qian Shengyue and Zhang Xuqiang over Divinity Radiation time, he refuses to back down despite the threat to his place in the Special Selection Class 44.

His friendship with Li Yi is casual and humorous. He jokes with Li Yi, complains when outplayed, and openly enjoys Li Yi's deceptive strategies when they benefit the team 37 67. He can also be envious of Li Yi's strength and the attention Li receives from Chen Qiong Zhi, but he continues training alongside him rather than distancing himself 46.
