This question surprised Tao Cheng and Wang Bingyu.
This was because the question was already very in depth. Normally, ordinary people would not ask such a question.
"Research has shown that there is a type of stone on the island called 'Bas,' which undergoes accelerated weathering and releases oxygen when exposed to high temperatures. This is why scientists refer to it as solid oxygen. As a result, the oxygen content on the island is slightly higher than in other places."
"Let's not talk about how magical this prehistoric civilization is. If we take back this Bas stone, material science should advance by leaps and bounds, right?"
"That's true, but the agreement stipulates that bringing it out of the island is strictly prohibited. If anyone discovers this, the warships of various countries will attack them mercilessly, which is why it has remained there to this day." Tao Cheng smiled and shrugged.
