For the same sect, there is a big difference in strength between those who have the mountain protection formation and those without the mountain protection formation.
Of course, it is unimaginable to spend precious materials and crystals to arrange and maintain a complex formation.
Nangong Yu nodded and said: "This formation should have evolved from an ancient formation, minus many complicated formation patterns, it is relatively not difficult to decipher, at best it can only be regarded as a fifth-rank formation."
"If what is here now is the original formation, I want to break it, it will not be so easy."
Hexi's eyes were filled with love for Yi Cai, and he couldn't help but said: "The magic formation is really amazing, I want to learn it too."
Nangong Yu rubbed her head, smiled dotingly and said, "Okay, I'll teach you!"
The two walked along the passage, and soon came to a place similar to an alchemy room.
But the most conspicuous thing in this room is not the alchemy stove and the table, but the portrait hanging behind the table.
The woman in the portrait looks cold, but she has a beautiful face and beautiful 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 blankly at the portrait, couldn't come back to his senses for a long time, and didn't even hear Hexi calling him.
Hexi was inexplicably unhappy in his heart, leaned close to Nangong Yu's ear and whispered, "Why, isn't it beautiful?"
Nangong Yu suddenly came back to his senses, and immediately said reflexively: "In my heart, Xi'er is the most beautiful."
"Come on!" Hexi snorted coldly, "I saw you were dumbfounded just now, your eyes were staring straight, you were almost drooling, and you said you weren't pretty?"
Seeing the little girl wrinkling her nose and staring at him, Nangong Yu couldn't help laughing.
He said that the little girl hugged her into his arms, pinched her nose, smiled happily and sweetly: "Xi'er, you are so cute! You can even be jealous of a portrait. But this king likes it." You look so jealous!"
Seeing that He Xi was about to get angry, he quickly said: "Don't worry, except for Xi'er, all other women look the same to me, even if they stand naked in front of me, I won't be moved."
He Xi wanted to refute him with a sullen face, "Who is jealous", but she couldn't help the corners of her mouth curling up.
Nangong Yu looked more and more curiously, lowered his head to hold her lips, kissed her gently for a while, and then continued: "Xi'er, I always feel that this woman looks familiar, where did I see it? Uh... It seems a long time ago seen."
Hexi said angrily: "Don't think about it, she is An Lingyue, Nalan Hexi's biological mother, and you have seen her portrait in the Herb Garden. It is normal that she looks familiar!"
Nangong Yu shook his head and said, "The portrait of An Lingyue in the Herb Garden has gentler eyebrows. At that time, I just thought she resembled you, so I didn't think much about it. But now when I see this painting, I always feel that it is inexplicably familiar. Where did you see it?"
"Don't think about it! People are similar, and things are the same. Maybe you misread it?"
Nangong Yu nodded thoughtfully, "Maybe!"
The two wandered around the room for a while, and soon found another secret passage leading deeper underground.
Hexi had a hunch that what was hidden in this secret passage was the real secret of Nalan Zhengze.
The two covered up their traces and quickly entered the secret passage.
