Brother Tian was injured, he clutched the wound on his left rib as he returned to the small courtyard, taking three times longer than usual to open the door of the house, and upon entering his room, both the smell of blood and sound were completely blocked off.
This was not due to the soundproofing of the walls, but rather, that room had some sort of special barrier which could block out sound, smell, and perception.
Originally, Tang Luo had been wondering what could be in such a small room to produce such a strong smell, necessitating the use of an array to conceal it.
Now he knew; it must have been the other party treating his wound, worrying that the smell would be detected.
After all, some spiritual beasts are extremely sensitive to the scent of blood; once injured, there was no escaping their pursuit.
Some sorceries and witchcraft could even use original blood in their spells to track down their target.
