Capítulo 525: Chapter 525: Dragon Cave is a cage?

At this moment, countless people were watching Ning Fei’s live broadcast.

Marine experts, spectators, archaeologists, scientific research departments, and so on.

The foreign countries were also enjoying such a magical scene.

This was the South China Sea, the deepest blue hole in the world.

At this moment, the discussion about this matter was also very heated.

[ he has already passed through the hydrogen sulfide layer! ]

[ is he alright? ]

[ there is no oxygen below the hydrogen sulfide. It is just stagnant water. No large marine animals will survive. ]

[ not necessarily. There are still many unexplored secrets in the sea. ]

Ning Fei continued to dive.

The sea became darker and darker.

The feeling of claustrophobia invaded everyone.

This place looked even scarier than the Kurubala Cave.

The netizens knew that the sea water here was poisonous.

Every minute and every second, Ning Fei faced great danger.
