When Ma Lu had first entered the secret chamber, his gaze was instantly drawn to something on the wall, but out of politeness, he first checked the message left by the Pointy Hat.
It turned out not to yield much useful information.
The video left by the Pointy Hat was based on the scenario of successfully completing his thesis and returning to The Grand Alliance, but the developments thereafter had completely diverged from his expectation.
He hadn't managed to leave the promised gift for the traveler who discovered this place, but at the same time, he hadn't taken any of the items in this room with him.
Ma Lu walked over to the wall and removed the blue metallic object hanging there.
Its design resembled a household drill a bit, with a handle and a switch, a thin metallic head on the front, and an oval slot at the back, plus three buttons in red, yellow, and green on the side.
