The cave was dim, only a sharp whistling sound was heard, and a huge blunt object was felt moving in the darkness, Shen Feng exclaimed, "What!!"

"It's coming—" Ye Jiang's skirt shouted urgently, "Lie down!"

The pot of wine hurriedly shouted: "You can't lie down, there are still mechanisms underground!"

Shen Feng hurriedly said, "Then what should I do?"

"Retreat first, one fast and one slow to confuse the mechanism!" At the moment of danger, the pot of wine temporarily responded with a unique method, and the three of them slowly retreated in a chaotic manner, while the blunt weapon in front roared and gradually approached.

Shen Feng's eyesight in the dark was still okay, and after adapting to the darkness, he saw the huge blunt weapon a little clearly, it turned out that the blunt weapon was a circular sawtooth, which was larger and larger than the sawtooth he had seen before, and it was much more difficult to drive, and to maintain such a large rotation speed, the precision of this mechanism could be seen.

"If you go down further, it's the wall!" the whistling sound grew louder and louder, and it hurt a little to scratch my cheeks, but if I didn't think of a way, I was afraid that this thing would be cut into six pieces.

Jujiu stopped groping with his hands, stood up and whispered, "Senior sister, you use the hilt of your sword to knock on the walls on the left and right, and then return to the center!"

Ye Jiangskirt knocked the hilt of the sword on the left and right walls according to her words, and then returned to the center, while knocking on the wall, the huge sawtooth suddenly split into two, and half of them each transformed into a T-shape and moved forward at high speed, until it hit the wall, it did not stop, and then retracted.

The three of them dodged without danger, Shen Feng took a long breath and asked, "Uncle Shi, why did the mechanism split into two after knocking on the wall twice?"

Jujiu said: "How to design the mechanism, is nothing more than figuring out people's hearts, ordinary people encounter this sawtooth, they will retreat to both sides, and will never stand in the middle, and there are actually copper sheets behind the two walls, and the sound of the copper pieces is used to judge the actions of the trapped people, so I asked my sister to knock on the copper plates, and the organs will naturally look for people." ”

After that, he said proudly: "How, boy, if you are not convinced, it is better for you to worship me as a teacher, I see that you call me my junior sister master, and you have not learned anything." ”

Others apprentice to see talent, Shen Feng apprenticeship is to look at the thigh, this thigh is not the other thigh, it is the proverbial hugging of the thigh: "My master is beautiful and can fight, when she fights, I can watch her fight, and you, you know a little bit of organs, belong to an unpopular profession." ”

The pot snorted dissatisfiedly.

Shen Feng turned to Ye Jiang's skirt and said with a smile: "Master, don't worry, I will never leave you." ”

Ye Jiang's skirt glanced at it lightly, unmoved.

Rumble –

It was not long before the cave was quiet, and suddenly there was a sound, and the pot of wine hurriedly alerted: "The mechanism has been activated again! Be careful!"

"Again!"

At this time, the masonry on the ground suddenly moved, to be precise, in a regular arrangement and combination, and it was only then that it was discovered that all the stone bricks in this cave were square, not the rock walls in the previous cave.

After the stone bricks were reassembled, the cave also changed shape, and the original rectangular shape was moved and rearranged to become a huge sphere, and the three of them stood at a point within the circle, and before the three of them could figure out what was going on, the sphere began to roll.

The sphere is rolling, but it doesn't happen, like a rotating globe.

The three of them kept running in the circle, trying to be vigilant, in this case, it was difficult to concentrate at all, even if they couldn't stand steadily, at this time, the top of the original shape shot arrows, the three had to dodge to the sides, but they also lost their center of gravity and fell into the ball, and the arrows on it were still firing, and the three of them dodged in a panic to be able to pick up their lives.

The spherical shape rotated for a while, and then began to become slow, and after standing at one point, it began to rotate in the opposite direction, and while turning, the arrows began to shoot from the other direction, and after repeating, the circle began to rotate in four directions, and the arrows were also fired from different directions, and gradually, the pot began to find a pattern, and the arrows were fired one by one with the direction of rotation of the ball.

Just when the three of them caught the rule, the ball suddenly stopped, the ball stopped, Shen Feng felt uneasy in his heart, and the pot of wine and Ye Jiang's skirt didn't say a word, in the dark, he whispered: "Why did you stop?"

Jujiu took the opportunity to grope for a moment and said in a deep voice: "Yes." ”

Shen Feng said thoughtfully: "Why don't I try to forcibly break it!"

"No, if we destroy the mechanism, we will be trapped here forever." ”

Shen Feng sighed helplessly, and said thoughtfully: "The reason why the ball can rotate is that there must be a gear pushing outside the ball, and there is an arrow in the middle of the gear, and every time you pass a tooth, an arrow is shot, so although the arrows of Fang Cai have different directions, the time between them is the same." ”

The pot nodded.

Shen Feng's expression suddenly brightened and said: "Uncle Shi, have you ever seen a zipper? You think about it, this ball is also combined from the uneven and neat teeth, just like a zipper, and it will be closed until the end, so we just need to find the last position of the zipper, and we can come out!"

Hearing this, the pot of wine slapped his thigh hard, and said excitedly: "Good boy, it makes sense, so in this way, the opening is in——"

The two said in unison: "Directly above!"

At this moment, kerosene came out of the ball, smelling this smell, Shen Feng's face immediately changed greatly, at the same time, the ball began to rotate again, due to the rotation of the ball, the kerosene also spread, and at this time the kerosene flowed out, obviously trying to set fire!

Shen Feng and Jujiu quickly rushed up to find the place where the opening was, and sure enough, there was a small opening at the end of the 'zipper', Shen Feng struggled to pull left and right, like a butterfly breaking out of the chrysalis, at the same time, a flame behind him spread out in a fan-shape, Shen Feng was the first to jump out, followed by Ye Jiang's skirt and pot of wine, and the giant ball behind him turned into a furnace, if it was a moment later, he would definitely be burned alive.

"It's dangerous!"

After escaping, Shen Feng immediately pinched a cold sweat, then looked at Ye Jiang's skirt and pot of wine, and saw that they were also safe and sound, so he smiled helplessly and said, "This time the mechanism is more dangerous." ”

Ye Jiang's skirt said rarely: "If you stay like this, sooner or later you will die under the organs." ”

Jujiu said in a low voice: "The more dangerous it is, the more you can find an exit, I feel that the exit is about to appear, you hold on a little longer, boy, I underestimated you before, it seems that it is not a fluke that you can pass through the imperial tomb." ”

Shen Feng reluctantly smiled and said: "As you said, whether it is an organ or a person, it must follow the basic principles of all things, I don't understand the mechanism, and some of the theories I have learned can also be applied to the mechanism." “

Jujiu nodded approvingly: "Not bad!"
