Suddenly, she noticed that the lower right corner of the photo was obviously much older than the other three corners.

A trace of doubt rose in Dong Yilan's heart, this photo was pasted on the tombstone and did not move, why there was a corner that looked particularly old, as if it was often held in people's hands. Her slender fingertips caressed the photograph, and the bumpy touch came from the fingertips, as if the photograph was a switch.

Mo Yao leaned over, he also found something unusual about the photo, there was a trace of worry on his cold face, and he gently held Dong Yilan's hand, "I'll come." The cold-sounding voice came into Dong Yilan's ears with a gentle tone, and her tense heart suddenly relaxed, and he took his hand away.

The slender fingers pinched the lower right corner of the photo and gently picked it, and the photo was taken down.

What catches your eye is a circular knob.

A hint of surprise flashed through Mo Yao's deep eyes, which was not only surprised by the doctor's choice and mastery of the location, but also by the doctor's design of the mechanism and the psychological grasp of the psychology that people would not touch the photos on the tombstones. Imagine who comes across a grave when they are full of food and will want to take down the photo on the tombstone to see if there is a mechanism inside.

Dong Yilan also looked at the black knob on the tombstone in surprise, and after hesitating for a moment, he wanted to reach out and turn it.

Mo Yao shook Dong Yilan's hand again, "You stand back." Leng Jun's face was full of worry, he was afraid that she would be hurt by the opportunity, so he insisted on touching the mechanism himself, so that Dong Yilan would retreat so as not to be injured by the hidden weapon in the tomb.

Dong Yilan wanted to say that his strength was actually strong enough, but when he saw the man's stubborn face, he silently retreated behind Mo Yao. I have to admit that the feeling of being protected by others is really very good, and Dong Yilan cherishes this precious touch.

There is no password for the rotation, it is just heavier, and Mo Yao needs both hands to exert force at the same time to turn it.

Rumble!

The stone slab in front of the tombstone sank, opening a one-meter-square entrance, and then something flew out of the entrance, Mo Yao turned around dexterously, and quickly retreated three or four meters to protect Dong Yilan, and her wide arms protected her entire body in her arms, forming a warm protective circle for her, shielding her from dangerous erosion.

Dong Yilan felt an inexplicable warmth in his heart, from meeting him to now, he has given himself too much touch.

After a long time, there was an explosion in the sky, and the thing didn't seem to have much lethality, and flew straight into the sky to explode a fireworks, some like fireworks, but brighter and more durable than fireworks, even in the daytime, it looked brilliant and incomparably bright.

"It's a flare," Mo Yao said, "and I guess now the doctor knows that someone has opened his tombstone." ”

"We have to move fast." After Dong Yilan finished speaking, the two quickly got up and walked to the entrance.

The entrance was a series of steps, winding down from one side of the tomb, and the two of them saw that there was no danger before they walked in, and there was no light source in the long passage, only the light from the entrance, and it was dark at a glance. I don't know how far the steps went, but they came suddenly, without any light equipment, and could only walk forward by a little dim light from the top of the cave. Mo Yao walked in front, holding Dong Yilan's hand, and the two of them walked down the steps step by step, the sound of high heels hitting the stone surface was crisp, ethereal, and with bursts of echoes, reverberating back and forth in the space as black as splashing ink.

In the clinic, the doctor had already seen the rising flames, and the signal flare was launched, which means that the secret in the graves of Ming and Qing'er had been discovered.

He kept the secret for 17 years, and it seems that he can no longer hide it.

The doctor was not angry but laughed, but the smile on his face was obviously bitter and helpless, as if a sad person remembered the sad past, and it was like an infatuated lover in the face of the moment when his lover left, that kind of piercing pain, even the whole person fell into a hopeless sadness, and the huge sadness on his body that could not be ignored made people who passed by and saw him couldn't help but be infected and sad.

His originally clear facial features were now distorted and gathered together, as if he was suffering some kind of unbearable pain.

After a long time, he muttered, "Qing'er, you also hope that he can find you, right?" ”

Turn around, lock the door, and hang up the sign that is closed.

The stairs have been extending down, there is no end to the long one, the two of them don't know how long they walked, they only felt that the further down they went, the cooler the temperature became, and the air became thinner, Mo Yao took out the Zippo lighter, lit the fire, and the two of them lit up with a hazy vision in front of them.

"We've got to get here for about a kilometer, right?" Dong Yilan asked, a pair of red eyes in the dim light are even more enchanting, treacherous, as if from another world of evil spirits, with an innate unique charm. She stared at the long passage suspiciously, and it seemed that they had guessed that the passage should have been diagonally to the bottom of the sea.

"When you're tired, take a break." Mo Yao said.

There was a gurgling sound of water under his feet, and the hollow echo seemed to come like the sky, extremely far away, and he wasn't sure how deep this passage was, but the depth of the seabed plus the slope, to say the least, was more than ten kilometers, and it had been downhill, which hurt her knees very much, Mo Yao felt sorry for Dong Yilan's body, and wanted her to rest here for a while.

"I'm fine." Dong Yilan's hand in Mo Yao's palm shook it hard, silently transmitting the power, Mo Yao understood, and continued to lead her forward.

The Zippo's firelight jumped in the narrow space, illuminating the path under their feet, but the shadow did not last long, and soon the Zippo ran out of gas, and the faint flame flickered, extinguished, and the world fell into darkness again.

Mo Yao visibly felt the footsteps behind him pause.

"Are you afraid?" She's afraid of thunder, so she's afraid of the dark, right? With a pain in his heart, he clenched the small hand in his palm, and the fingertips were cold as if there was no temperature.

"Don't worry, I'm fine." She was as fragile as he thought, and a little darkness could scare her! The joking voice sounded in his ears, and Dong Yilan pursed his lips and smiled. Mo Yao also smiled, laughing a little distressed, a trace of guilt flashed in her eyes, if she had brought Yilan home, this qiē would not have happened, she was still the innocent little girl, chasing after him like a little fart every day, calling her little brother over and over again.

"Little brother, little brother, I can't walk, can you carry me on your back?"

"Okay."

"Little brother, am I heavy?"

"It's not heavy."

"It's not heavy, so can you carry me on my back for the rest of your life?"

"Good!"

Such a heavy promise, never forgot jì, "Come up, I'll carry you on my back." Mo Yao stopped her steps, and squatted slightly in front of Dong Yilan, who was wearing high heels and was very tired from the road in front of her.

Dong Yilan was stunned, but she didn't expect that this cold-looking man was really good to her Cheng Dù.

"I'm not tired now, I'll sue you when I'm tired." She didn't want to be a burden to him, this passage seemed calm, who knew what kind of danger would be hidden inside, he carried her on his back, and the reaction speed would be much slower, and once he encountered danger, he would have no time to dodge. If something happens, it's something she doesn't want to see.

"Why, don't believe in your master's physical fitness?" The man who was despised by the woman was very angry, you must know that he Mo Qiye is an arrogant and domineering master, and suddenly lowered his posture to offer a courtesy, but was rejected, it was a very shameful thing, and he came up without thinking about his temper: "If you come up, come up, so much nonsense?" ”

Dong Yilan raised his eyebrows, and he was still angry! If you are willing to carry it, you will be able to carry it, and you will be tired to death! Thinking of this, Dong Yilan climbed onto Mo Yao's back without hesitation.

The man's steady footsteps continued to go out.

In fact, Dong Yilan's small physique of 100 pounds really can't feel the weight on Mo Yao's back, and he didn't take a few steps and the seventh master began to give his opinion, "It's too thin, I don't like it, I will make up for it when I go back, and I will personally supervise your meal." ”

Dong Yilan rolled his eyes, thinking that he was cooking himself.

"Don't think about it, I said, no matter how much weight you get, you can hold you." After a moment, he added, "Sixty pounds is no problem." ”

Dong Yilan's face is black, she is 170 tall, if she grows to 130 pounds, she is not thin, if she really reaches 160 pounds, how fat will she be, how can she see people? It's a shame that he can figure it out! But listening to these words, there was a warm current surging in her heart, from head to toe, and even the lower and lower temperature in the passage did not make her feel cold.

The further down they went, the louder the sound of running water became, and finally, at the end of the steps, they saw a waterwheel used to generate hydroelectric electricity.

"It's an electromagnetic field." East Israel said.

Next to the waterwheel, a blue laser connected to the ground, and lightning-like light waves flickered back and forth in the darkness, and Dong Yilan already felt that powerful power, right under his feet. Seeing the waterwheel rolling in the water, she couldn't help but sigh strangely, this doctor is really a genius, he actually brought water in from the bottom of the sea, and used the current to drive the waterwheel to generate electricity, such a huge project, I don't know how he did it alone.

"As long as the windmill is destroyed, the magnetic field loses its energy supply, and the gravitational pull disappears." Dong Yilan looked at the windmill slowly turning in the water, and was very puzzled, "You say that he is a doctor, how can he make such a delicate thing?" "It's supposed to be something that engineering students can only do.

"Maybe he's not a doctor by profession." Mo Yao's tone was cold, his eyes fell on the sturdy waterwheel, its design is very strong, it is not easy to dismantle it by manpower, if you use explosives to blast, I am afraid that this side has just been blasted, and the passage on the top has also been blown up, then there should be two more names on this tombstone.

He didn't want the three of them to be buried together.

"Look at me." Dong condensed his heart with blue, and the white blazing light in his palm instantly turned into a scorching red light.

"Yilan, don't ......" It was too late, a cloud of red light had already rushed in the direction of the waterwheel, Mo Yao's raised hand froze in the air, and there were only two words left in his mind, it's over...... If they are not buried alive now, they are sorry that they went to the bottom of such a deep cave.

Rumble!

The moment the streamer hit the waterwheel, the water splashed, and the sturdy waterwheel instantly shattered into a pile of waste wood and fell into the water, splashing a few people high, almost hitting the top of the rock, and falling into the pool with a bang, the edge of the pool was sparsely slammed, and the underground laser was gone.

Almost at the same time, the glimmer of light on the roof of the distant cave disappeared, and the cave was completely plunged into darkness-

Ahem, tomorrow Qixi Festival, how will you spend Valentine's Day?

Xiaoyan has thought about it, how about letting the Seventh Master and Qiao Qiao celebrate the festival in the hole where they can't see their fingers?
