บท 540: Installing a Signal Device

Lu Ye smiled and said, "Plastic bottle."

Zeng Sanshui was filled with curiosity and asked, "What material is it made of?"

The plastic bottle was processed from oil extraction. This was not a secret in the southern frontier.

Even if Zeng Sanshui was told, he would not understand.

Lu Ye did not want to waste his breath because Zeng Sanshui had too many questions.

If he answered, there would definitely be another question.

He did not want to answer, but he saw Qu Yuanxian and the others looking at him curiously.

Lu Ye remembered that they were envoys and it was necessary to promote the achievements that their country was proud of.

He held the plastic bottle and said, "This is a plastic bottle made of black gold water."

"Black Gold Water?"

Everyone looked unconvinced.

The black gold water was black, oily, and smelly. It could only be used as a flammable material. How could it be made into such a beautiful bottle?
