Secret Treasure and Marrow Crystal

At first, a plain-looking, middle-aged man paid 11 million for a fist-size aerolite.

The aerolite, which was particularly angular, had also caught Li Yao's attention.

According to the Bountiful Treasures Pavilion, the aerolite had been shining in seven different colors when it fell into the Heaven's Origin Sector. There was even a video clip to prove it.

But other than that, it seemed to be a perfectly normal stone.

Examinations suggested that 99% of the stone was made of regular metals and only 1% of it contained the unknown materials that had never appeared in the Heaven's Origin Sector before.

In the end, the middle-aged man, after spending a fortune on the mysterious aerolite, took out a syringe of grey liquid which he poured on the stone.

Then, the aerolite started shining in various mystic colors, which was exactly the scene where it first entered the aerosphere. The shining didn't stop until three minutes later.
