It is the same sect, but the difference in strength between having a mountain protection formation and not having one is huge.
Of course, the amount of precious materials and crystals required to set up and maintain a complex formation is unimaginable.
Nangong Yu nodded and said, "This formation should have evolved from an ancient formation. It has removed many of the complicated formation patterns. Relatively speaking, it is not difficult to crack. At best, it can only be considered a fifth-grade formation."
"If what's here now is the original formation, it won't be so easy for me to crack it."
He Xi's eyes were filled with lingering thoughts, and he couldn't help but say, "Array formations are really magical. I want to learn them too."
Nangong Yu rubbed her head and smiled lovingly: "Okay, I'll teach you!"
The two walked along the passage and soon came to a place that looked like an alchemy room.
However, the most eye-catching thing in this room is not the alchemy furnace and the table, but the portrait hanging behind the table.
The woman in the portrait has a cold expression, but a stunning face with beautiful eyes and eyebrows. She is Nalan Hexi's biological mother - An Lingyue.
When Nangong Yu saw An Lingyue's portrait, a look of obvious surprise appeared on his face.
Then he stared at the portrait blankly, unable to come back to his senses for a long time, and did not even hear He Xi calling him.
He Xi felt inexplicably unhappy, so she leaned close to Nangong Yu's ear and whispered, "Why, is she very beautiful?"
Nangong Yu suddenly came back to his senses and immediately said reflexively: "In my heart, Xi'er is the most beautiful."
"Don't give me that!" He Xi snorted coldly, "I saw that you were stunned just now, your eyes were wide open, and you almost drooled. And you still say that it's not beautiful?"
Nangong Yu looked at the little girl in front of him who was frowning and staring at him, and he couldn't help laughing out loud.
He hugged the little girl in his arms, pinched her nose, and smiled very happily and sweetly: "Xi'er, you are so cute! You are even jealous of a portrait. But I like the jealous look of you!"
Seeing that He Xi was about to get angry, he quickly said, "Don't worry, except Xi'er, other women all look the same to me. Even if they stand naked in front of me, I won't be tempted."
He Xi wanted to retort with a stern face, "Who is jealous?", but he couldn't help but raise the corners of his mouth.
Nangong Yu looked at her more curiously. He lowered his head and kissed her lips. He kissed her gently for a long time before continuing, "Xi'er, I always feel that this woman looks familiar. I seem to have seen her somewhere before? Hmm... It seems like I have seen her a long time ago."
Hexi said angrily, "Don't think about it. She is Nalan Hexi's biological mother, An Lingyue. You have seen her portrait in the herb garden. It is normal to find her familiar!"
Nangong Yu shook his head and said, "The portrait of An Lingyue in the Hundred Herb Garden had gentle features. At the time, I just thought she looked like you, so I didn't think much about it. But now when I see this painting, I always feel that it seems strangely familiar. Where have you seen it before?"
"Don't think about it! People are similar, things are the same. Maybe you are seeing things?"
Nangong Yu nodded thoughtfully, "Maybe!"
The two wandered around the room for a while and soon found another secret passage leading deeper underground.
He Xi had a hunch that hidden in this secret passage was Nalan Zhengze's real secret.
The two covered their tracks and quickly entered the secret passage. (To be continued)
