427 This Little Girl Is A Unique One 2 (1/2)

The mussel was considered to have done an excellent job as it could dig half a mile of railroad in an hour.

”Mussel, have you been staying in the fifth mountain since the beginning and left before?” Gu Xijiu highly suspected the possibility.

”Yup.” The mussel added, ”I’m a mussel, I don’t have to go out.”

Indeed!

Gu Xijiu smacked her head as she wanted the mussel to dig a path to the upper ground. However, she seemed to have sensed something. She walked further and placed her fingers on the freshly dug wall.

There was something on the wall!

Since it was just soil, she took out a blade and poked it. However, the blade could only penetrate about an inch into the wall and stopped. Something in the wall was restricting the penetration.

The blade could even penetrate an iron wall in a single poke, not to mention the soil. However, there was something stronger than metal behind it!

She simply scraped away the soil and finally saw the object in the soil, it was a layer of transparent membrane. The blade bounced back when she poked it, what was that?

”Wizardry barrier! Master, this is a wizardry barrier!” The Firmament Stone screamed in Gu Xijiu’s mind.

Wizardry barrier!?

Gu Xijiu heard about it before; rumor has said that the monk who had a very high spiritual power could set a wizardry barrier and it could block whoever or whichever living things from entering or escaping. It was stronger than any wall. However, wizardry barriers were usually set above the ground. This was her first time seeing a wizardry barrier underground.

Apparently, the wizardry barrier was set to prohibit any form of entrance and exit.
