There was a special biogas pool in the underground palace. With thousands of years of biogas accumulated, it would not be a problem to keep the underground palace warm for decades.

This equipment was more mature, advanced, and practical. The longer it took, the more obvious the effect. He Yi was deeply impressed by the craftsman who built this palace. However, the overall mastermind behind all of this was only one person -- Queen Loulan!

This was indeed a woman full of wisdom. She had planned everything so meticulously and meticulously. However, she had arranged the underground palace so meticulously and comfortably as if it was to receive visitors after a thousand years.

Why did she treat the intruders so well? Could gentle give a reasonable answer to this question!

In He Yi’s eyes, gentleness was no longer just an explorer, an outdoor activist, an archaeologist, a geological explorer, and an architecture researcher... he also had another title, which was an expert in deduction.
