The gate is inlaid with eighty-one huge golden rivets, which can be felt to weigh three catties just by looking at the appearance, and there is a vacant position in the left and right corners under the gate.

The code to open the door is simple, move these rivets to the right place, it's a bit like a digital maze, you need to crack it yourself.

When he opened this door, it was completely by luck, if he had to say that he also had hard work, he had the strength to hang four meters high with one hand and move four catties of willow nails with his bare hands.

It's not hard to unlock the door, and if you look closely, you can see a subtle pattern on each of the willow nails that glows. There are animals, there are mountains, there are stars, etc., and when the patterns are successfully rehearsed in a specific order, the door can be opened.

Si Xiuwen carefully observed these patterns, his mind was frantically calculating, the various patterns were randomly arranged in various combinations, and it didn't take long for fine sweat to break out on his head.

And Xin Shuitong, who didn't know the situation on the side, looked at him with a puzzled expression, "Isn't it just to open the door, as for so long?" ”

"Young master, otherwise let's give up, these patterns are not fixed, they will change with time and the degree of the sun, and it will be even more difficult to unravel them." Seventeen persuaded Si Xiuwen on the side, he had also tried to open this door, tried more than a thousand times, but without exception, all failed.

Xin Shuitong, who was on the side, was full of curiosity about this door, especially hearing Seventeen's explanation, which stimulated her desire to explore even more.

As a forensic doctor, she has a strong ability to search and analyze details and hidden spots, and she carefully observes these patterns and gradually becomes attracted to them.

"What a beautiful carving!" She sighed from the bottom of her heart, these changing mountains and rivers, insects, fish, birds and beasts, etc., on the surface of the willow nails, as if they would move, lifelike.

Seventeen looked at the strange couple from the sidelines, and couldn't help but sigh deeply, one was the most persistent, the other was full of curiosity, his words didn't let them listen, he didn't bother the two of them anymore, he waited silently on the side.

The light gradually dimmed, and there was a slight chill in the air, and night fell.

......The leaves were blown up by the wind and curled in the air, and everything around them became very quiet.

From dawn to dusk.

Xin Shuitong had already returned to the car, sitting on the seat of the car and eating snacks, "How long will he want to think!" ”

She sat quietly in the car, looking out at the forest in the distance, and always felt that there was a great attraction there. Suddenly, there was an exclamation in the forest, and in an instant a group of birds flew up.

"Cuckoo, cuckoo." The cuckoo, whose feathers are snow-white, chirps loudly, and is very noticeable among many birds.

The movement in the distance had already attracted the attention of Si Xiuwen and Seventeen, and the two of them looked up at the forest one after another, a trace of surprise and doubt flashed in their eyes.

Si Xiuwen's mind was running wildly, and he calculated more than 10,000 permutations and combinations, but when it was always implemented, the most critical step was missing, and in the end it could only end in failure.

The cuckoo's chirping broke his thoughts, and he subconsciously looked at the eighty-one willow nails on the gate, and suddenly found that in an inconspicuous position, he found that there was a pattern of cuckoos.

"Young Master!" Seventeen looked at Si Xiuwen with some surprise. He had seen this strange phenomenon for a long time.

Si Xiuwen stared at the cuckoo's pattern for a long time, and began to slowly try to move the willow nails, and the key point was around the cuckoo.

"Squeak, babble." The sound of moving willow nails is particularly uncomfortable, and no one knows what the structure of this door is, only that there was this stone door in the great-grandfather's generation.

Xin Shuitong got out of the car and shone a flashlight on the wall, providing him with brightness and vision, so that Si Xiuwen could see these willow nails clearly. Seventeen, on the side, was always vigilant, paying attention to any changes around him, protecting the safety of the two.

Maybe because he had tried a few times before, Si Xiuwen moved the willow nails very slowly this time, but it was very smooth and there was nothing wrong with it.

Finally, with a roar and the sound of the machinery running wildly, the black stone gate began to slowly open outward, and Si Xiuwen protected Xin Shuitong and began to retreat, waiting until the stone gate stopped moving.

At this time, the stone gate was filled with white mist, blurring the vision ahead, Si Xiuwen's eyes narrowed slightly, trying to see the things inside, but except for the white expanse, he couldn't see anything clearly.

Suddenly, a bright light lit up in the white mist, and the light gradually approached them, brighter and brighter. A figure gradually appeared in front of them, and with it, there was a huge sense of oppression.

Si Xiuwen recognized who the person was at a glance, the corners of his mouth were a little stiff, but he still stubbornly went up, "Father." He shouted respectfully, not daring to slack off a little.

Xin Shuitong, who was hiding behind Si Xiuwen, couldn't believe her ears, she could hear the respect for his father in Si Xiuwen's words.

It's just that...... This father-in-law on her face seems to be a little indifferent. When the two got married, he didn't show up, and she once thought that Si Xiuwen only had a mother.

The white mist gradually dissipated, and she finally saw Si Xiuwen's father's appearance clearly. Dressed in a black tracksuit, wearing a brown peaked cap, and a pair of eagle-like eyes under the hat, the whole person looks like a sharp sword, with a sharp momentum.

"Why did it take so long to open this door?" The man's voice was stern.

Si Xiuwen took her hand and didn't answer for a long time.

Seventeen wanted to bury his head in the floor, hide in the darkness through the skills he had learned, and desperately try to lower his presence.

Xin Shuitong looked at the reaction of the two in amazement.

They were like rats and cats at this time, pitiful and trembling.

"Seventeen, wait for me in the training room." Hearing this fluttering command, Seventeen's body trembled unconsciously.

He didn't want to go to that place again!

It was discovered.

With a drooping face, he stepped out of the darkness and entered through the doorway.

"The more I live, the more I go back." Si Nanmin's gaze fell back on Si Xiuwen, and he glanced at Xin Shuitong as if he was nothing.

Sensing his gaze, Xin Shuitong raised his head and looked straight over.

The body also shuddered uncontrollably.

She hurriedly lowered her head and hid herself behind Si Xiuwen. I can't help but complain a little in my heart, so decent, why did he bring himself here?
