At this point, there was no need to continue the experiment. Zhao Hai already knew the general use of the black crystal. The rest of the experiment could be carried out slowly. Now, Zhao Hai only wanted to do one thing, and that was to wait until night time. Then, he would go into the forest at the bottom of the lake and find the source of the soul Origin Energy.
Time passed by and soon, the sky turned dark. After Zhao Hai and the others had their meal, everyone went to rest. So did Pu Li and the others. They were going to the forest with Zhao Hai the next day, so they needed a good rest.
When the sky was completely dark, Zhao Hai left his tent and went straight into the forest at the bottom of the lake. The forest was still as bright as day. All the plants were emitting a blue light, making the bottom of the lake look very beautiful.
