For the next three days, Zhao Hai and Shi Yan had been searching for the ground worms in the poison fog pool. When they finally found the ground worms, Zhao Hai had found three, and Shi Yan had found two.
All the wire worms they caught were put in the steel pipe. One end of the steel pipe was sealed, and the other end was plugged with a buckle. In order to prevent the wire worms from being suffocated, there were some small holes on the steel pipe, which allowed the steel pipe to breathe without letting the wire worms out.
The underground worm was a kind of poisonous worm with a strong vitality. If it was put in the steel pipe, it would not die even if it didn't eat or drink for a few months. Moreover, after Zhao Hai and Shi Yan caught the underground worm, they directly put it in the steel pipe and then put it in the mud. Although the underground worm couldn't escape from the steel pipe, it could touch the mud, so they wouldn't die.
