Chapter 22: The mastermind behind this incident has been found

Unlike pioneering the mine area, in this world, even with his vast knowledge reserve, Tang Xian was far less adept.

For instance, he was currently in a grocery store where, although the exteriors of items were covered in dust and some moss,

it didn't hinder identification, yet Tang Xian couldn't recognize these items.

Well... let's just pretend he didn't recognize them.

Tang Feiji seemed to have smelled the scent of lubricating oil from a small package.

He opened the bag and took out something resembling a balloon.

"What is this?"

"This is a type 0.1 ultrathin balloon, which has many uses. It can be used to store water, or you can blow it into a balloon for fun when bored."

Tang Feiji seemed half-comprehending.

Initially, Tang Xian couldn't recognize those tools, but after seeing the "balloons" Tang Feiji unpacked, he roughly knew what the grocery store sold.

Shaking his head, Tang Xian walked out of the grocery store.
