Elders yin and yang followed Zhao Hai to the entrance of a cave dwelling. There were two cultivators standing in front of the door. Both of them were actually experts of the bichen realm. The two of them stood there expressionlessly. When they saw the three of them coming over, the two cultivators looked at them and said in a deep voice,"Password!"
"The Yin Yang token has been issued. Return the order!" Elder Yin said.
"Peerless domineering blade!" The cultivator said in a deep voice. Please, elders." The two elders nodded and walked inside.
Zhao Hai was stunned as soon as he entered the cave. There was a long and gloomy passage. On both sides of the passage, there was a cultivator standing every two meters. All of these cultivators were in the dust-free realm. This was beyond Zhao Hai's expectations.
