"Uh~~! How big is the area that needs guarding, and what strength is required?" Liu Qinghe asked.
"It's quite large, about the size of this palace, and it's also quite deep underground," Mu Rufeng replied.
"In that case, I recommend the Demon Vine, which usually lies dormant underground. The underground is pretty much its stronghold, and it can even burst through the soil to attack enemies on the surface."
"And since it's usually underground, it takes some effort for enemies to remove the Demon Vine."
"In terms of strength, there are levels from one to seven available. I recommend you purchase the level seven, as we have special methods of control, allowing even ordinary people to claim ownership."
"Once planted, it will absolutely not act against its master's wishes, nor will it attack others without reason, even if they are alive," Liu Qinghe said.
"What about level eight? Are there no level eight Demon Vines?" Mu Rufeng asked.
