Zhao Hai didn't know what was going on with this space, but he was sure that there must be something in it that was constantly absorbing spiritual Qi. Otherwise, it wouldn't be like this.
With a thought, a few crystals appeared in Zhao Hai's hand. These crystals were huge. If they were placed outside, people would definitely fight over them. However, there were a lot of such crystals in Zhao Hai's spatial space, so he didn't feel any heartache.
As soon as the crystals were taken out, the energy inside was absorbed by the space. Zhao Hai took out another crystal, but it was not absorbed completely. Zhao Hai felt like he was giving food to a starving person. He would eat as soon as he saw food.
After a long time, Zhao Hai suddenly felt that the speed of the spiritual Qi absorption in this space had slowed down. In the end, it no longer absorbed the spiritual Qi from his body, but directly absorbed the spiritual Qi from the crystals.
