The teen – who carried out his crimes with hammers – was jailed for life last month.
After the two students sustained “multiple serious injuries” at Blundell’s School in Devon, Huang faces a minimum term of 12 years behind bars for attempted murder.
Devon and Cornwall Police responded to reports of a serious assault in the early morning of June 9 2023.
Huang used weapons he had collected to prepare for a zombie apocalypse to attack his schoolmates and housemaster, Exeter Crown Court heard.
The student admitted to assaulting the trio, claiming that he was sleepwalking.
To execute the attack, Huang carried three claw hammers and waited for the two schoolboys to fall asleep.
The students were sleeping in cabin-style beds in one of the school’s boarding houses when the then 16-year-old got up and attacked them shortly before 1am on June 9 last year.
