Poison for Plants

It was a cylindrical black object inside the box.

After a look, Yang Guang picked it up and weighed it with his hands. It was not very heavy, and it didn't feel like metal. Instead, it felt like wood.

Lu Wenwen had keen eyes. She found that there seemed to be words at the bottom of the object, so she told Yang Guang, "Look at the words here! Poison for Plants?"

"What?"

Yang Guang was a little confused. He looked at her and asked.

"It explains what this object is. This is a special character from ancient times," Lu Wenwen explained.

"Then, it's a kind of poison?"

Yang Guang scratched his head, and then an idea flashed through his mind. "Does it mean that this thing is the reason why there are no plants around?"

"Literally, it should be. It's the poison of the plants, and that's why the surroundings have become a barren mountain." Lu Wenwen said.
