Chương 233: Gold Certificates

An Jiuyue pursed her lips.

She knew what was in the box even without Wei Na's reminder. Why else would she search the entire house for the key to open this box?

The box was divided into five levels. The first level had a button that could eject all levels like a staircase with a press.

There were five bamboo tubes on the first level. Red and beautiful, the bamboo tubes were authentic and customized.

If Qian Jiyun was here, he would be able to tell that these tubes were used by the military to transmit messages. Each bamboo tube had been soaked in special medicine. Water could not corrode it, and it could even withstand fire for a while.

An Jiuyue picked one up and began opening it to inspect it.

"It's stuffed with paper. Why do I find these papers familiar?" she muttered to herself.

The paper in the bamboo tube felt different from ordinary paper. It was slightly yellow as if she had seen it somewhere before.
