Kapitel 2031: Crystal Card

After three days of closed-door training in the Mystery Land, Li Lingtian had settled some matters.  

The three rings of the Wutian World Master were an astronomical amount of wealth.

For the time being, he could only use three Connate cardinal treasures, countless materials, and countless medicinal herbs. There was no need to mention spirit stones.

In his opinion, the most precious thing was still that magical crystal, because that crystal alone occupied an interspatial ring. The space inside this interspatial ring was tens of thousands of miles in circumference and hundreds of miles in height.

However, there was only one crystal card in this interspatial ring. It was ten centimeters long, five centimeters wide, and one centimeter thick. It was crystal clear and colorful. It was about the same size as a normal jade slip, but the only thing that mattered was its color.
