The woman's crisp and pleasant voice made Chen Mobai wake up instantly, and there was a faint amount of water vapor in his warm eyes.

"It doesn't matter." He smiled faintly, "I just happened to think of a tune that matched the notes on the correct bluestone bricks that I had just walked by." ”

So, he sang in a low voice again. His voice was low and magnetic, and the music came out of his mouth in an indescribable beauty.

Jun Qinglan came from a scholarly family, and has been involved in piano, chess, calligraphy and painting since childhood. However, Chen Mobai hummed this tune, which she had never heard before.

"What's this tune?"

Chen Mobai lowered his head, and his eyes seemed to be a little dim: "It was an ancient song that I occasionally heard when I was in exile, but now I am afraid that I can't hear it anymore." ”

Exile?!

Jun Qinglan was very surprised by this word, what has Chen Mobai experienced over the years?

Chen Mobai smiled lightly: "Why bother? Compared to you, I've suffered only a few minor setbacks, and I'm not worth mentioning. ”

Jun Qinglan smiled and did not have any extra words. Although Chen Mobai's background is low, his self-esteem is actually extremely strong. He despises the pity of others for him.

According to the tune of the song hummed by Chen Mobai, Jun Qinglan pressed the correct brick, and the two finally passed the long and dark corridor. Looking back at the road they had walked, they all breathed a long sigh of relief.

Standing on the last note, they saw another wall.

The wall was unlike anything I'd seen before, with a huge hourglass in the middle of it, but not half of the sand had fallen. Beneath the hourglass are ten vermilion square stone bricks, each engraved with numbers from one to ninety-nine, and one blank.

Jun Qinglan looked at it for a while, and suddenly exclaimed: "Nine Palace Grid? It's actually a nine-square grid?! ”

"What is the Nine Square Grid?" Chen Mobai looked at her with a little doubt in his eyes.

Jun Qinglan took a breath: "It's an ancient technique. This kind of technique has been lost for a long time, but I didn't expect it to appear here. ”

Jun Qinglan became more and more curious about the builder of the dungeon, who could use this long-lost knowledge to the mechanism?

Chen Mobai said with a smile that he didn't care, "Compared with this number technique, I think Ah Wei is a treasure." First the thunderbolt fire bomb, and then the nine-square grid, all of which are very insightful. I haven't seen him for so many years, Ah Wei is really impressive. ”

Jun Qinglan smiled and waved her hand: "Mo Bai, you are a false praise." You have forgotten that there is a rather old wooden box in our library. My father said that the books in the box were left by the ancestors, and they were a rare treasure, but no one was allowed to read them at will. Daddy said that if you can use it properly, you will become a talent in the world like your ancestors, and you can assist the holy monarch and help the world, or you can destroy the world. Thunderbolts, fireballs, and the Nine Square Grid are exactly what is recorded above. Hey....... ”

Jun Qinglan looked at Chen Mobai: "That year, you and I were greedy to play and enter the library building privately, didn't you read this book together?" How did you forget? ”

"Hmm." There was a touch of gloom and sadness in Chen Mobai's eyes, and he quickly passed by: "The age is too long, I don't remember it for a long time." ”

Jun Qinglan sighed: "Now that I think about it, it makes sense for my father to carefully store that book at the beginning. If it falls into the hands of someone with a bad heart, I don't know what kind of uproar it will cause. At the beginning, the Qin family was burned clean by a fire, and this book must have been burned as well. It's a shame. ”

Chen Mobai half-lowered his eyes, and the smile on his cheeks was just hidden in the shadows: "Maybe." ”

Jun Qinglan didn't speak for a long time, and her clear eyes stared at Chen Mobai for a moment: "Mobai, can I still believe you?" ”

The smile on Chen Mobai's cheeks froze for a moment, and after a while, he raised his face and looked at Jun Qinglan with warm eyes: "Chen Mobai is always Chen Mobai, why did Ah Wei say this?" ”

Jun Qinglan frowned fiercely: "You never seemed to lie to me before!" ”

Chen Mobai pursed his lips, and sighed heavily after a long time: "After all, I can't hide it from you, I knew I couldn't hide it from you!" ”

Jun Qinglan's eyes were slightly dark, and there was a bit of thought in her eyes: "Kong Chen, but you killed it on purpose?" ”

"Yes."

"Did you bring me here on purpose?"

"Yes."

"You also leaked the news of the camp?"

"Yes."

Jun Qinglan's voice condensed like ice: "Who is the real gap in the white camp?" ”

"It's me."

"Why?"

"To stay alive. Only by being alive can I have the opportunity to investigate the Qin family's case clearly. Return the Qin family, and give you justice! ”

Chen Mobai's gaze was confused for a moment: "I was originally the gap between Princess Changle and the white camp. Whether it is the actions of the black camp or the white camp, it is up to me to secretly ward princess. Kong Chen had seen me above, and he must die! Since I have the intention of luring you in, I naturally can't let him divulge my secret. Although all of this was designed by me and Kong Chen a long time ago, I couldn't fully trust him. ”

Chen Mobai's voice paused slightly: "I do this to live!" ”

"Purpose?" Jun Qinglan said coldly: "What is the purpose of you trying to lure me here? ”

Chen Mobai smiled bitterly: "I'm just a person who acts on orders, how much do you think a fine work can know?" ”

"Princess Changle's order?"

Chen Mobai shook his head: "Do you think the real owner here is Princess Changle?" She doesn't have that qualification. ”

Jun Qinglan breathed and condensed: "Are those people in blue?!" You've had multiple chances to kill me, so why don't you do it? ”

"Huh." Chen Mobai chuckled: "How could Ah Wei think that I would kill you?" I didn't know it was you at first, but when I saw you, I knew it was impossible. ”

Chen Mobai took a breath: "My heart for you has never changed, in the Jiedu Envoy's Mansion, I already knew it when I first saw you. You will be the one I will protect for the rest of my life. I will never hurt you! ”

Chen Mobai's voice paused slightly, and then he laughed self-deprecatingly: "It's really ridiculous to say such things now, how can you believe it?" Even I can't believe it. ”

The blood on the man's pale face receded. At this moment, Chen Mobai looks like a lifeless puppet, which can die at any time.

Yu Jinyun was silent, and only after a long time did he raise his head: "I believe it!" ”

The most difficult thing in the world to measure is the human heart.

Jun Qinglan has always been very curious about Chen Mobai's privileges in the secret prison.

Although he is handsome, there is no shortage of handsome people in the white camp. What's more, he doesn't have an amazing background and identity, so why do all the vicious killer demon kings in the black camp shy away from him?

Except at the behest of their master, he did not think of it.

He didn't understand why the real master of the black camp would let her in, and even let her discover the secrets. Looking at it now, it is completely impossible to make her disappear here quietly. She thought about this question for a long time, but she still couldn't get to the point.

However, the owner of the black camp did not know about her relationship with Chen Mobai.

By the time they met, many things were different from what had been planned.

Her side is full of dangers, and Chen Mobai is doing his best to protect her. If he hadn't pushed himself out of the snake cave and let himself fall into it defenselessly, where would he have a chance of surviving?

No matter how things change in the world, he is still the Chen Mobai who takes care of her in every way under the magnolia tree!

Chen Mobai's eyes suddenly miraculously regained their brilliance when she said what she believed. The bright light was dazzling in the darkness of the tunnel.

"Thank you for believing in me. I won't let you down! He said.

After a long time, Jun Qinglan finally lowered her head and said softly: "Now, finding a way to unlock the Nine Palace Grid is the right way. ”

Chen Mobai saw that she didn't care about Fang Cai's affairs anymore, and the corners of her lips finally hooked: "I have long forgotten about the book, what is the matter with Jiugongge, please tell me about it?" ”

"The nine-square grid is a simple formation made up of nine numbers. Numbers from one to nine appear once in the squares and are never repeated. All the cracker needs to do is find a way to line them up. So that whether they look horizontally, vertically, or diagonally, as long as the three numbers arranged in a straight line are added, the result is exactly fifteen. ”

Chen Mobai took a breath: "How is this possible? ”

Jun Qinglan said: "It's really not easy. I don't know how to do it, so I have to try my best. ”

Chen Mobai bowed: "This time, I'll come." ”

"Nope." Jun Qinglan did not hesitate to stretch out her hand to stop: "I'll come." ”

Chen Mobai's eyes darkened, and he no longer insisted.

Jun Qinglan smiled: "It's not that I don't believe you. It's just that I've seen this kind of thing in the past and secretly studied it for a while, and although it's been a long time, I still have some impressions. Now it should be faster. ”

Chen Mobai only smiled slightly and did not speak.

Jun Qinglan's fingers had just touched the square brick, and the only square brick without inscription retracted without warning. A large hole suddenly appeared on the wall, and at the same time, the hourglass on the wall suddenly turned upside down, and the fine sand contained inside began to flow slowly.

And a deafening roar sounded in their ears.

When the sound stopped, countless sharp spear heads instantly popped out on the walls on both sides of the far behind, and the cold light flashed terrifyingly. The spear-tipped walls were moving, slowly gathering towards them at a speed visible to the naked eye.

Chen Mobai took a hard breath of cold air: "What a poisonous mechanism!" ”

The nine-square grid is the only way to open the secret door, but when you touch it, the hourglass will turn upside down. The inversion of the hourglass causes all the traps in the dungeon to open. If you can't put the nine-square grid together before the sand falls, you will inevitably be tied into a hedgehog by the wall covered with spear tips.

The mechanisms here are interlocking, making it impossible to prevent people.

Jun Qinglan didn't seem to be disturbed by the external crisis. In the course of dealing with all kinds of dead corpses for several years, she has developed an extraordinary courage and carefulness.

The sand in the hourglass was falling faster and faster, and the tip of the spear was getting closer and closer to the two of them. Jun Qinglan's fingers also increased the speed of movement at the same moment.

As soon as she had moved the last brick in the right place, the last grain of sand fell from the hourglass.

Suddenly, peace was restored between heaven and earth.
