Contrary to expectations of a gloomy and dark place, the base was brightly lit.

Moreover, the brightness is not achieved through artificial lights or other lighting tools, but rather through sunlight that is extremely close to the outside world.

The sunlight shone on them, and everyone could even feel the warmth of the sun.

But how is that possible?

In just ten minutes, they have climbed at least a thousand staircases. If each staircase is 0.2 meters high, they are now at least 200 meters underground.

How could sunlight possibly reach such a depth?

Mu Yin noticed the shock on everyone's faces, his gaze swept over Qin Sheng, and a strong sense of pride appeared in his eyes as he said, "No doubt about it, this is the sunlight."

"Not only sunlight, but also moonlight and starlight at night. Simply put, the lighting environment inside the QS base is almost exactly the same as on the ground."

Everyone was shocked once again.

As the head of the first experimental base, Wei Zhenyun, although primarily focused on biological genes, also had some understanding of and paid close attention to other aspects.

Upon hearing this, his eyes lit up, and he quickly asked, "Was this also designed by Lord Q?"

Mu Yin nodded: "That's right. This is also because Lord Q used the principle of light refraction and reflection, and through special materials, combined with the light introduced by the ancient formation, to restore the external environment to the greatest extent possible."

This is...this is too amazing, too fantastical!

I just want to ask, what kind of genius is this Mr. Q? How can he be so amazing and achieve this level of skill?!
