The mysterious man nodded yes.

Nie Tian suddenly thought of whether it was possible to add zero a month ago, and it became a four-digit password, 0215, and informed the mysterious man of his thoughts.

The mysterious man shook his head and said: "This possibility is almost zero, the ancients did not have the habit of adding zero before the month, but now when accounting accounts, add zero before the single number of months to prevent tampering." Moreover, the ancients had other names for the months, such as January was called the first month and the first month, and February was called the middle moon and the flower moon,...... So the kind of thing you're talking about isn't very likely. ”

After a pause, the mysterious man then sighed: "The architectural structure and mechanism design here are all discovered for the first time, which can be described as exquisite, and if the discovery here is made public, it will definitely cause a sensation in the archaeological world and shock the world!" ”

Listening to the mysterious man's explanation, Nie Tian was impressed by the wisdom of the ancients, and couldn't help but say, "Since the password is not wrong, it must be something missing."

I know that most of the mechanisms of the ancients were fixed with shrapnel and circlip, with levers and gears, and most of the power was provided by potential energy (boulders) and water energy.

Just like the flap floor tiles on the first floor, most of them are made of potential energy. ......”

When the mysterious man heard this, he interrupted Nie Tian and suddenly said, "Thank you little brother for reminding me, I understand." ”

Hurriedly walked to the center point of the circular platform (the hollow cylinder), tapping on the pillar with a flashlight, looking for something.

Everyone also quickly followed, expecting the mysterious man to find out.

It didn't take long for the mysterious man to make a discovery, and gently pulled out a moving green brick from the cylinder with a crowbar, and under the green brick, there was a hole the same size as the first layer of the mechanism.

As the hammer fell, a "click" was heard, coming from the hollow cylinder.

Brother Huo took the lead, walked to the cylinder, probed in, shone a flashlight on the sound, and carefully observed it for a while.

He turned to everyone and said, "There is a hole down here, about 3 or 4 meters deep, and there should be a passage on the side of the bottom of the hole."

The hole is very narrow, we can only go one at a time, and we can reach the bottom of the cave by holding the wall with our hands and feet. ”

Nie Tian listened to Brother Huo's description, and always felt that something was wrong, but he couldn't say what was wrong.

Brother Huo walked in front of everyone, preparing to arrange the order of going down the hole, Mao San hid at the end, obviously not daring to go down the hole first.

Brother Huo didn't bother to take care of him, so he arranged for everyone to say: "Brother Long is the first to go down to explore the way, Xiaotian is the second, the second is you, and Mr. and I are behind." ”

Brother Huo's intention in this arrangement is obvious, he can't put Nie Tian in the first place, in case he has the opportunity to attack the people behind him after he goes down first.

It can't be put at the end, it's just as easy to attack the person in front.

Beware of Nie Tian everywhere, but he didn't mention Mao San, I don't know if he was taking care of his brother-in-law, or if he was tired of him to the extreme.

Everyone went down the hole in turn, and Brother Long was agile, sliding to the bottom in two or three times.

The cave was so small that I could only poke the side with my foot and shout to it: "There is a passage on the side, but the passage is very short, and I can't bend over, and I am big, so I can only crawl or sit down and rub forward." But you can probably walk in a squat. ”

Nie Tian thought about it, Brother Long's big and tall man must be aggrieved down there.

After speaking, Brother Long sat and rubbed into the passage, and after waiting for a while, Brother Long shouted inside: "There's nothing wrong, you can come down." ”

Nie Tian's body flashed, and he slipped to the bottom of the cave with both hands and feet.

Hold your hands on the walls of the cave and put your feet into the side passage, then lean back and enter the passage little by little.

The passage is also made of green bricks, which is very delicate and slippery to the touch. The further along the passage he went, the more slippery it felt, and the steeper the slope became, giving Nie Tian a sense of foreboding.

Everyone came down one after another and entered the passage, and Nie Tian used super hearing to guard the surroundings.

Everyone was in the passageway, slowly rubbing forward, and after a long time, the slope had made everyone have to support the wall with their hands and feet, barely to keep from sliding.

At this time, Nie Tian heard Mao San at the back, and said in pieces, "Fuck, I knew I wouldn't be here, what kind of bullshit expert, I made a password for a long time, it turns out that the fucking channel mechanism is somewhere else." ”

Mao San's complaint reminded Nie Tian, it is true that this passage is wrong, if opening this passage has nothing to do with the password, it doesn't mean that there is another passage, if that passage leads to the place we are going, then where does the one we are walking now lead to?

Nie Tianzheng was thinking in his heart, whether to discuss with everyone, whether to continue, only to hear Mao San's "ah~~", and fell in response.

The following people were affected by Mao San, one by one sliding towards Nie Tian, under the effect of gravitational acceleration, if several people were pressed on their bodies, Nie Tian not only could not stop them, but also might be injured.

Nie Tianxin was horizontal, let go of his hands and feet, and slid down the passage.

The speed of the slide exceeded expectations, and in an instant, Nie Tian's feet had reached the top of Brother Long's head, and at this moment, he completed the analysis in his mind: the weight of the four people above was almost more than seven hundred catties, plus the impulse of gravitational acceleration, it was definitely above a thousand catties.

Although the super made his body much stronger, he didn't want to be big, and he didn't want to be used as a meat pad when he landed.

Moreover, to be merciful to one's enemies is to be cruel to oneself.

Nie Tian made a quick decision, and as soon as his feet landed on Brother Long's shoulders, he kicked down hard. Brother Long's blocking only made him pause for a moment, and then the two of them quickly slid down together.

The speed is getting faster and faster, and if you fall down according to this momentum, you will definitely break the bone and die.

Nie Tian was ready to roll forward at the moment he landed, unloading the momentum of the landing, so as to avoid the four people behind him, so as to avoid being torn apart by the organs that they had stepped on.

The expected landing did not come, but after sliding sharply to the bottom, the whole person leaned diagonally to form an upward angle with the horizon, and the feet jumped diagonally upward.

Nie Tian immediately understood in his heart that this was a "U" shaped passage.

The design is very ingenious, using the person's own gravitational acceleration, just like riding a slide, quickly gliding from one end of the passage to the other end of the "U" shaped passage.

Not long after, Nie Tian felt a huge inertia and squirted out of the "U" passage with his feet diagonally upward, and the moment he left the passage, he used his afterglow to capture the black shadow of Brother Long dangling by, already standing firmly in place.

In order to avoid colliding with Brother Long, Nie Tian used force on his waist, drove his whole body to twist, his lower body sank, facing the passage, and he stopped steadily half-squatting and half-kneeling, and put on a cool pose of a superhero.

The whole process was like flowing water, without the slightest delay, Nie Tian was really satisfied, and forgot to get up for a while.

I only listened to the four people in the back, like playing solitaire, from the mouth of the passage.

Nie Tian hurriedly flashed, and he could dodge.

I saw the four of them come out one after another, Brother Long's body was heavy, and he rushed to Brother Jin horizontally, hugged him from his chest, and dragged him aside.

There is no more time to help others.

The mysterious man followed, his body was clumsy, and at first glance, he didn't have any kung fu in his body, Nie Tian's figure flashed, and when he came to him, his arms stopped his waist, and he drew an arc, leading him to avoid the two people behind.

Brother Huo is also a practitioner, his body turned, his hands propped up the ground, and he rolled on the ground horizontally, unloading the momentum, and also dodging Mao San behind.

Mao San was already fat, and the inertia of this rush was greater than that of others, and he didn't have much effort, he crossed a long arc in mid-air, rubbed the back of his head on the ground first, and then slapped it heavily.

It hurts to look at.

After Mao San landed, there was no sound, and he didn't know whether he was dead or alive.
