Capítulo 268: It’s Time to Go Back

Sang Qianqian stood by a small lake on the west side of Professor Fu'er's small courtyard, nervously watching the busy workers.

The thick layer of ice on the surface of the lake was smashed open, and the water inside was quickly sucked dry.

The excavator's shovel moved the mud and searched carefully.

More than an hour later, a heavy metal box with a height of around two meters was dug out.

The box was washed clean and transported back to Professor Fu'er's residence. It was covered in rust, but one could still vaguely see that it was an old safe. The number on the password lock could still be distinguished.

"When my daughter passed away, I thought Fu'er was the main culprit. In my anger, I put all the treasures in his laboratory into this safe and threw them into the lake."

Caroline carefully entered the password, and the old safety lock actually opened with a click.
