When he got underwater, Situ Fang tried hard, and those golden nails could indeed move inside and out. According to Zhang Gong's instructions, Situ Fang soon set all 28 nails. As the work was done, no reaction appeared. Situ Fang didn't give up, and dived to the stone gate to take a look, but the stone gate was still closed, and the expected effect did not appear.

Zhang Gong hovered, looked at the nails again, and saw that all the nails were moved according to his instructions, and there was no mistake, and he couldn't think of the reason for a while, so he pointed upwards, and several of them all went up.

Zhang Gong took off the equipment and said, "It shouldn't be, there's no reason for no reaction." ”

Professor Chen is not very good at the mechanism, and Zhang Gong is a little decadent, so he said encouragingly: "If the position of the nails must be all correct, it may be that you have ignored some details, don't rush, and study it slowly." ”

"If the nails are all in place, then why not trigger them? What could be overlooked? ”

After saying this, Zhang Gong fell into deep thought. I walked to the side and studied the photos for a long time, but I still didn't figure it out, and the day's work was over.

At night, Zhang Gong lay on the bed and tossed and turned, wondering why the stone door under the water had not been opened. It wasn't until 11 o'clock that he finally figured it out, shook Professor Chen up excitedly, and said loudly: "Old Chen, I know why the stone door hasn't opened!" ”

Professor Chen turned on the light and asked in a daze, "Found the answer?" ”

"Yes! I did overlook one detail! ”

"What details?"

"That's what I said in the Immortal Hunting Formula."

"Don't sell it, let's talk about it."

"This passage in the Immortal Hunting Formula, you have listened carefully, 'Treasure Hunting Mountain, right first, high and low peaks, occupy the middle sky, Tenglongqi, look at Pingchuan, secret clouds, there must be immortals, help its left, proud first,' you now understand what I want to say, right?"

"Are you saying that the three stone statues in the middle also need to be adjusted before the mechanisms below will take effect?"

"Yes! I just pushed the stone statue on the right over, but didn't put him in place, the whole mechanism should be pushed away from the stone statue on the right first, which is equivalent to turning on the limit function of the mechanism, and then the nail below can be adjusted, so as to adjust the setting in the lock, and after the nail is adjusted, a program is also needed to lock the results that have been set below, and then through a stone statue, in fact, it is the start button, the trigger of the mechanism. ”

"Are you saying that the stone statue on the right is put back in place, set to lock it, and then push the stone statue on the left and in the middle to trigger it?"

"Exactly!"

"Now that you know the answer, let's go to bed and go in early tomorrow morning."

Zhang Gong, who got the answer, soon fell asleep. In the middle of the night, a man did not sleep, but quietly came to the waterhole, and sat quietly on the side, in a daze. Seeing that the water was calm, he sighed, walked over to the stone statue in the middle row, and prepared to push the stone statue on the right back.

At this moment, two white shadows rushed towards him one after the other, and when one of them approached him, the courier scratched his face, and then quickly ran to the front. In this way, the blood seeped out of the scratches, and soon, from seepage to flow; Another white shadow, almost at the same time, grabbed him hard in the back of the heart, causing a few more blood cuts on his back, and under the rapid attack, a piece of his clothes was also torn off. He covered his hot face with one hand, endured the pain in his back and face, and shone the white shadow just now with a flashlight, and with the beam of the flashlight, he saw the two white shadows clearly, which turned out to be a boy and a girl. Suddenly, he was frightened and screamed, "Ghost! Then he crawled along the way he came, and escaped.

Early the next morning, Zhang Gong took people and equipment and walked happily to the waterhole. As soon as he walked down the steps, Situ Fang saw a small piece of cloth on the side of the stone statue opposite the waterhole. This discovery immediately alerted him. After he stopped everyone from moving forward, he went over to pick up the cloth, looked around with a flashlight, and found a few more blood droplets on the ground, and said to Professor Chen: "Professor, it seems that some things happened here after we left. ”

Professor Chen walked up to him, looked at a few drops of blood at Situ Fang's feet, and asked, "Is there a fight here?" ”

"It should be, and someone is hurt."

Professor Chen turned off his headlamp and asked loudly, "Who walked at the back of the line yesterday?" ”

Team Fan took a step forward and said, "Yesterday it was me and Chen Zhijun and Lei Tongren, and there was no problem. ”

Chen Zhijun and Lei Tongren hurriedly walked out and nodded in confirmation.

Professor Chen looked at the blood stains under his feet and said suspiciously, "If it weren't for the fact that one of us quietly stayed, then who would have slipped over?" ”

Team Fan took the fragments of the clothes from Situ Fang's hand, looked at them and said: "This is the material on the sportswear, such a black sportswear, it seems that not many people wear it, and the monitoring should be able to find out who is wearing it, and who went out from here last night." ”

Situ Fang added: "There is a small drop of blood on this clothes, and there is a lot on the ground, which means that the person is injured, and based on this, it should be easy to find." ”

Team Fan nodded, and after explaining a few words to the deputy captain beside him, he took someone with him and ran away immediately.

When Professor Chen saw that Team Fan was gone, he turned the topic to the main topic and said loudly to everyone: "Through Zhang Gong's efforts in half the night, I have worked out a way to open the stone gate below, Situ, you will take the two of you to put on diving suits and equipment in a while, and after Zhang Gong finishes it, I or Zhang Gong will call you, and then a few of you will go down." ”

"Okay, take two more people, with a video camera?"

"Yes, you stand with me, and the rest of us go back to the passage!"

Seeing that Professor Chen had finished speaking, Zhang Gong squatted down in front of the three stone statues in the middle and looked at their feet again. After reading it, he saw that except for Professor Chen, Situ Fang and a few others, the rest of the people had already retreated into the passage, so he smiled at Professor Chen and pushed the stone statue on the right back from behind. After pushing back the stone statue, Zhang Gong stood in front of the middle stone statue again, took a deep breath, and then pushed the stone statues on the left and in the middle back one by one.
