Wu Feng was stunned for a moment, then came back to his senses and smirked: "No...... Grandpa, these two things, the apprentice grandson has seen before, I remember when I and Xiao Huang first entered the cave, you still let me guess what this thing is, if I guess wrong, I will roast the apprentice grandson and the yellow-haired monkey, but the apprentice grandson did not guess correctly, your old man still let me go...... Thinking about how this has happened for almost a year, it seems as vivid as what happened yesterday. ”

The white-haired old man smiled, shook the two things in his hand, and continued to ask: "Then you stinky boy guess now, what is this thing in the hands of the ancestor grandfather?" ”

Wu Feng shook his head and said with some embarrassment: "The apprentice grandson doesn't know what it is used for now, why don't you tell the ancestor grandfather to tell me, this thing looks strange, and the apprentice grandson has never seen it when he is outside." ”

The white-haired old man stretched out his other hand and took out the long thing like a ruler for measuring clothes, a little black, it didn't look very inconspicuous, it shook in front of Wu Feng's eyes, and then said: "This thing in the hand of the ancestor grandfather, you kid didn't guess it right at all, but you guessed half right, this thing is called "corpse ruler" Do you know what it is for?" ”

Wu Feng shook his head again, and said with some resentment: "Grandpa Zu, don't sell your old man to your apprentice grandson, hurry up and sue me." ”

"Hehe......" The white-haired old man smiled proudly, and then said: "This "corpse ruler" can be used a lot, you kid don't look at this thing black, it can be very useful, first of all, it can sense the yin and evil qi within a radius of ten miles, as long as there is something like a corpse within this range, this "corpse ruler" will turn black, and then a red dot will appear on it, the closer you get to the demonic thing, the brighter this red dot will be...... It allows you to quickly track down those evil things. ”

Wu Feng's eyes widened, and he looked at the so-called "corpse ruler" in the hands of the white-haired old man with a curious expression, and then looked up at the white-haired grandfather, and smirked: "Grandpa ancestor, the original appearance of this "corpse ruler" should not be black, right?" ”

The white-haired old man was stunned for a moment, and wondered, "How do you kid know?" ”

"Hey...... That's not simple, because the ancestor grandfather is also a kind of corpse, a jade corpse that has been practiced for thousands of years, can this "corpse ruler" not be black when you hold it in your hand? Wu Feng said boldly, but he still couldn't help but want to laugh.

Fortunately, the white-haired old man was like an old naughty boy, and he didn't mind that this little apprentice made a joke about himself, but just scolded with a smile: "You stinky boy, no big or small, although your grandfather and I are a jade corpse, but also your grandfather, how can you be offended by this junior!" ”

"Who let Grandpa Grandpa, you have no shelf at all? The apprentice grandson is not afraid of you at all. Wu Feng patted his ass.

As he spoke, he took the "corpse ruler" in the hands of the white-haired old man, and looked up and down in his hand, this thing was cold in his hand, and it felt a little slippery, like a piece of warm jade, the weight in his hand was quite heavy, but the material was a little like iron, and some of it was like a hard wooden board, and he couldn't tell what it was made of for a while, what puzzled Wu Feng the most was that the red dot that the grandfather said was not shown on this "corpse ruler".
