Late at night, a flight from Jiangnan City to Malaysia slowly took off!
On the plane, Ye Feng glanced through the window at Jiangnan City shrouded in the night, a devilish smile curling at the corner of his mouth!
The human experiment this time was highly successful, and it also showed Ye Feng the tremendous value of the Energy Source Stone!
At this moment, he took out a small black box from his pocket, which held half a piece of the Energy Source Stone!
Only a tiny piece of the Energy Source Stone is needed for human experiments, but Ye Feng chose to carry most of it with him, just in case!
"Research on the Energy Source Stone is still at the primary level! There will be greater development value in the future!"
Ye Feng's eyes sparkled. Now, he would not blindly use the Energy Source Stone on his Blood-colored Maple Leaf members, because it's still unclear whether the Energy Source Stone has any side effects, or how much damage it could cause to the human body!
