Da Xian Special Chapter 26: Friendships start to form
On the first day they arrived, Ping Hu created a perimeter with the sylvan venomous snake's blood which he still had plenty of it left. After he had checked, none of the beasts around here could break through the perimeter. Due to the enormous size of the perimeter, Ping Hu had to ask everyone to help send a little of their qi to the perimeter.
They spent all of the evening creating a temporary camp. They would build a permanent camp tomorrow because they would have to stay here for a while. Ping Hu was the one who suggested this. It was because if it rained hard and there was a flood, the temporary camp would be wiped away by the water.
