Every single one of them started undergoing the thunder tribulation but they realised that they have underestimated this world too much.
They were seemed to be discovered by the consciousness of this world, the power of the thunder tribulation is a tier higher than it should be.
Countless lightning strike descended unto them, each one of them started circulating their body tempering art, Qi cultivation technique and Beast Swallowing Technique.
Boom! Boom! Boom! The thunderstorm was relentless, especially since this world doesn't want them to survive, meanwhile, Qi Nulong and her fellow sect disciples were finishing up cleaning the remnants of the Ten Thousand Venomous Snake Sect.
None of the disciples have died but most of them were heavily injured, the only reason why they survive is because of Qi siblings and the elite sect disciples of their sect.
