Lu Yao arrived at an abandoned classroom carrying something.
He opened the lead box and took out an ornament with an "eye in the middle of a triangle".
This palm-sized object was the "Star Key" obtained from the Otherworld.
He had tried many methods without any reaction, but the one Zhang Xin gave him had activated.
At this moment, Lu Yao was about to "replay" the process. Zhang Xin had smeared the "Star Key" with radioactive material, so he decided to try the same!
Moreover, he would use even more force!
~~~~~~~~~~~~
Lu Yao placed the "Star Key" on the podium and retreated ten meters, then took out a can-shaped container holding "plutonium-239".
He sent Mind Force into it, only to see the silver can rise from the ground as if held by an invisible hand and slowly float toward the podium.
When it reached the spot, Lu Yao clenched his hand sharply, and under the effect of Mind Force, the can unscrewed itself in mid-air.
