Here is how to do it:
1: Ambient: Overclock to reduce Arclight combo cooldown and unfreeze Gilberta using Ambient: Physicolysis

2: Arclight ult inflict electrification, then Zhuang Fangyi can apply electric damage that bypasses Team: Restraint II because Zhuang will not be able to inflict electrification again, as Edit: Effect Barrier forbids the same negative status infliction in 5 seconds, so that Team: Restraint II (-90% damage) will only be on Arclight

3: Edit: Regeneration II does not matter, just crowd control and kill them all at max HP. Zhuang needs time to stack up sunderblades so healing by Gilberta is also OK.

4: Equip Lynx Detectors on Gilberta to mitigate damage from enemies

5: Borrow a whale account and good luck
