Yang Hao sighed and said: "With such a small hole, I'm afraid that only weasels or pangolins can climb into it, of course, pythons and larger black-haired mice can also climb in, but only we humans can't." ”

"Do you know biomimicry? It's true that human body characteristics are not suitable for climbing such small holes, but if you know a little bit about bionics, you may be able to draw inferences and find a way to climb in. Fu Ying prompted.

"Okay, I'll try it as you say. Yang Hao closed his eyes and began to think seriously. He thought that since such holes were only suitable for animals such as weasels, pangolins and pythons, humans would have to use the principles of biomimicry to imitate these animals.

Yang Hao also discovered a phenomenon, that is, the body shape of these animals is streamlined, that is, the body is like a narrow thin line, which can basically be consistent from head to tail, unlike some large mammals, the head is small, but the body is very large, that kind of body shape is obviously not suitable for climbing, or drilling such a hole. The human body can also be seen as streamlined, and the key is to see how you make the body with limbs and limbs folded into streamlining. Therefore, theoretically, people should also be able to climb into such a hole. Of course, there is also the premise that your head must not be bigger than the hole.

After thinking about it, Yang Hao finally had a plan. I saw that he was lying on the ground, putting his legs together, and then his arms together, and slowly stretching forward, so that the whole body from the tips of his hands to the heels just became a straight cylindrical streamline.

Once he was in the pose, he began to implement his plan. I saw him slowly creep into the hole like a python, and then put a pair of arms into it. As soon as the arm was inside, his head was already in front of the hole. He measured the width of the hole with his head, and found that it matched his head. In other words, the head is able to get in. However, he found another problem, that is, his two ears seemed to be stuck, and he tried to squeeze them in, but it hurt to rub his ears, and he had to stop and think of a way.

At this time, he thought that if he pulled both ears with his hands and pressed them tightly against his cheeks, the ears would be able to enter smoothly. But by this time his arm was already in the hole, and there was nothing he could do to help. There was no way, he could only slowly adjust the angle and posture of his head, and kept trying. Eventually, he finally adjusted to a suitable angle and squeezed both ears in - he suspected that his ears had been rubbed off a layer of oil, but he couldn't care about it, getting himself in was the first thing at the moment!

Once the head was in, he moved his torso and thighs in (he found that this was exactly what he had guessed, as long as the head went in, the body would be able to get in).

It was pitch black in the cave, and I didn't know how deep it was, and I didn't know where it leaded, and it was like a water pipe, which went on and on. Because the hole was so narrow, Yang Hao could only squirm forward slowly, inch by inch, as if it had entered the food in his esophagus. This process is naturally quite long, and at the same time, the heat in his body cannot be dissipated, and he will soon be like soaking in a sauna, and his whole body is **. His nose smelled the rotten smell of dirt and the stench of dead rats and dead snakes. The smell was so smoky that he almost choked.

Only then did he realize how difficult it was for those tomb robbers to climb such a robbery hole. It seems that the tomb robbers have had enough of trying to get the lighter. But that didn't change his view of grave robbers. For in any case, it is a sin to dig up the graves of the ancestors! He has no contempt for this sin, and no mercy for it!

I don't know how far he climbed, he suddenly felt his head hit a hard object, this sudden collision made him unprepared, his head suddenly bulged a big bag, and he also let out a strange cry of "ouch".

"Brother Yang, are you okay?" Fu Ying's voice came to his ears again. It seems that Fu Ying has been paying attention to him. His heart was relieved and he replied, "I'm fine." ”

Just now, his arm has been stretched out in front of him, which actually plays a role in pathfinding, because in such a dark cave, there is no light source to distinguish, he can only rely on his own hands to probe and move forward. And his hand didn't touch any hard object just now, why did his head hit it?

"You've hit a tomb brick, and you're now in an ancient tomb, and this place is the boundary between the tomb and the outside. Fu Ying said.

"What? Why is there such an ancient tomb here? Could it be that your father actually built such an ancient tomb in order to test me?"

"This ancient tomb is already there, and it was not built by my father specifically to test you, but my father has transformed this ancient tomb to make its function more perfect, you have to deal with it carefully. ”

"Isn't this ancient tomb complicated?Where am I now?" Yang Hao asked Fu Ying while looking up and entering the tomb from the place where the tomb bricks were laid. After entering the tomb, he felt that the space was a little wider, and he was able to move his shoulders and stretch his arms and kick his legs freely, but the height of the space seemed to be insufficient, only more than a foot high, so he couldn't sit up at all, he could only lie down or lie on his stomach, but the space on both sides was very large, and he couldn't reach the edge of his hands or kicking his legs. Naturally, there was no light source in the space, and Yang Hao could only grope his way forward in the dark.

"You're in a funerary tomb right now, and this tomb isn't much bigger than the usual grave of an ordinary person. That's why you're so narrow. You have to find an iron rod and a fire breaker quickly. You have to take some precautions with the help of iron rods, and at the same time you have to light them with fires. Fu Ying reminded Yang Haodao.

"What? Why do I have to find an iron rod as a precaution? Is there any danger in this tomb? Also, you and Uncle Fu just put a few lighters, flashlights, or fluorescent sticks inside, why do you have to put such an old and backward fire fold?" Yang Hao wondered.

"As long as it is a tomb, there are naturally dangerous factors in it, from small corpse cockroaches that mutate due to eating dead human flesh to large zongzi, which are all possible. As for the fire fold, it was left here by a tomb robber a long time ago, and you can only use it for lighting now, and there are no lighters, flashlights, or glow sticks. ”

"Ah, isn't this the underground of your house? And this ancient tomb has also been transformed by your father, and those terrible things should have been removed by your father a long time ago, how can there still be?"

"All tombs are extremely yin places, and even if you get rid of the evil things here, after a while, they will move here from other places. In short, you have to do it yourself!" Fu Ying's tone was a little solemn. It seems that her warnings are by no means unfounded.

Yang Hao didn't dare to slack off, and cautiously groped back and forth in the tomb, trying to find out what Fu Ying said as soon as possible.

But I don't know if it's really harder to find something in the dark than to find something in the light, or what's going on, he touched it for a long time, and he didn't touch what Fu Ying said.

And there seemed to be a sound of Xi Suosuo in his ears, and he didn't know if it was a mouse or something. If it's a mouse, it's not a big problem, I'm afraid it's the "corpse cockroach" that Fu Ying said, this thing is said to eat dead human flesh, I don't know if it will also eat live human flesh?

Yang Hao's heart smacked a gedeng, and he reached out to the side and tugged hard, only to feel that he had touched a cold object, like a human arm. He shuddered, and his mind flashed, "What? There is a human arm in here? Whose is it? Is it just an arm, or is it a whole person?" He followed the arm down, and then touched the torso and thigh! It seemed that this was a whole person lying here! But judging from the form of this person lying here, this was a corpse!

"Yingying, how can there be a corpse here? What the hell is going on?" Yang Hao shouted at the surroundings. But Fu Ying didn't respond, and I don't know if I could hear his shouts, or if Fu Ying left at this time and couldn't hear his voice?

Yang Hao's heart was in a hurry, and he shook the hand that grabbed the corpse's arm - this was completely a subconscious action. But he didn't expect him to throw it off, and immediately pulled a piece of flesh off his arm! It seems that this corpse has reached the point of decay!

Before he could come back to his senses, he only felt a "squeak" scream in his ears, and then the piece of meat he was dragging in his hand was snatched away by something, and then there was a sound of chewing in the darkness, as if something was eating the piece of meat!

Yang Hao only felt a churning in his stomach, as if he wanted to vomit. But he forced his stomach back to sour in his throat, and at the same time quickened the search for it.

Fortunately, he finally touched a bamboo tube five or six centimeters long, and the mouth of the bamboo tube seemed to be stuffed with something. Yang Hao had checked the information before and knew that this thing was a fire fold. The principle of ignition is to pull out the roll of soil paper stuffed in the mouth of the bamboo tube, and then blow on the bamboo tube, and the flammable materials with a very low ignition point such as yellow phosphorus and nitrate contained in the bamboo tube come into contact with the oxygen in the air, and it will burn up and become an open flame!

"Pounce!" Yang Hao puffed out his cheeks and blew, and the bamboo tube really burned flames, and the beating fire light illuminated the entire tomb! Yang Hao's heart was happy, and he was about to see the surrounding environment clearly, but he didn't expect a Bai Sensen's arm to suddenly stretch out from behind him, and snatched away his fire fold!
