Chu Zhixuan smiled and said, "Really? I don't think I'm dreaming." After speaking, he said to the two guards, "Drag him down to me. You should know what to do." The two guards immediately took orders, and no one dragged Cheng Guodong's arm and took him out of the room.

   In another place, Leng Xuan stood in front of the square door, his brows slightly wrinkled, and his handsome face showed a trace of contemplation. The cave of this vampire is indeed very strange, and any strength that comes with infuriating energy will be repelled. Moreover, in such a place, it is impossible to use too strong force, otherwise, the cave is very likely to collapse. Just when Leng Xuan was confused, the ghost hand not far away sat on a stone, playing with a small stone and muttering: "Those guys from the blood clan have learned to play ghost tricks now." Throw the pebble at the square door. Suddenly, a strange scene appeared immediately. Seeing that the pebble easily crossed the restriction without being blocked, everyone was greatly surprised when they saw it. Leng Xuan quickly picked up a stone from the ground and threw it again, the result was the same as before.

   After thinking for a while, Leng Xuan rummaged in his pocket for a while, and found a coin. He tossed it casually, and the coin suddenly threw an arc and fell into the square door. Mu Qing couldn't help but wonder: "Why can all these things go in, but we can't?"

   Guan Hu said, "These things are all dead things. Could it be that only dead things can enter?" Leng Xuan shook his head slowly, without making a statement. He walked slowly to the restriction of Sifangmen, and slowly stretched out his hand. When he came into contact with the restriction, a rebound force immediately came, making him unable to move forward half an inch. Standing in front of the door and thinking for a while, he said, "Since this ban has no effect on these dead things, it means that this ban has entry conditions. As long as we can meet this condition, we can enter smoothly."

Mu Qing couldn't help but ask: "Then how do we know what this condition is?" Leng Xuan smiled and said, "This restriction is set by the blood clan for outsiders. In other words, this prohibition on the blood clan people is invalid. Then, The question arises, what is the difference between us human beings and the blood race?" The ghost hand sitting on the stone said, "Could it be the body structure?" Leng Xuan shook his head and said, "It's not this, although this restriction is powerful, after all It's just a dead thing, without wisdom, so what he resists should be very characteristic. Think about it, what is the biggest difference between a blood race and a human?"

After everyone's thinking, Guan Hu was the first to react. He clapped his hands and shouted: "I see, it's blood. The blood of the blood is cold, but the blood of us humans is hot. Leng Xuan, what I said. Right?" Leng Xuan smiled and nodded and said, "Although I'm not sure, but I think this possibility is very high, why don't we try it." After speaking, he stretched out his hand again to the square door. Probe. However, this time, he lowered his body temperature first. With his current strength, it is very easy to freely control the temperature of his body. But after he felt that his blood gradually became cold, he slowly stretched his hand into the restriction. Seeing his hand approaching little by little, Mu Qing and the others were full of expectations.
