After eating and resting, Wang Chengyuan and the dumb man also regained some mobility, the two did not dare to approach the thousand-year-old Xuanbing like Yunli, but standing on the periphery, they could also see the situation on the Xuanbing, a burly iceman lying flat on the Xuanbing, he didn't look very old, he looked like he was in his forties, but in ancient times, he could be regarded as entering the old age of his life. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The iceman's whole body is covered by Xuan Ice, and his body does not have any decay and dehydration, basically retaining his original appearance, wearing exotic style clothes, with various bone ornaments on his neck and wrists, it can be basically concluded that he is a Hun leader, and he has a bronze long sword on his side, which has also been integrated with the thousand-year-old Xuan Bing, and there are no other items.

"That's all there is, we can't find the information on the way out, and we finally picked up a life, do we have to be trapped here again?" Wang Chengyuan carefully probed around, and the forbidden bead did not react at all, so he had to sigh helplessly.

"There's still a place to explore, so you don't have to give up so early." Yun Li replied calmly, without any frustrated look on his face.

As soon as Wang Chengyuan heard that there was a play, but there was no place to explore, only the thousand-year-old ice in the center was left, so he asked urgently: "Could it be that this escape passage is under this huge ice block?" ”

"Do you remember the five coffin mechanism we broke through, it is this thousand-year-old ice that provides energy power to the mechanism, this is the main space, the other four spaces should be nearby, and these five coffin mechanisms are not perfect, they have to be set up according to the specific situation of this piece of ice, each independent space needs different energy, which forms the blind spot of this mechanism, and the craftsmen use this blind spot to build an escape passage between the two spaces with the largest energy difference." Yunli replied truthfully.

"There is this possibility, then let's quickly find a way to open the escape route, the food and water left now are estimated to not last a day, and after leaving the ancient tomb, we will have to go down the snowy mountains, and the road ahead is arduous." After hearing that there was an escape route, Wang Chengyuan and the dumb man's eyes lit up, Wang Chengyuan was anxious, and couldn't help but urge.

"The craftsmen opened the passage here, but it's been so long, and the ice block that could have been moved here has fused with the main body again, and we have to find a way to chisel it open." Yun Li pointed to the location of the lower part of the Xuan Ice Block.

This thousand-year-old Xuan Ice is as hard as iron, it is not feasible to chisel it by hand, although Yunli can use the green ox to create cracks, but this is not as good as digging ice plum blossoms, the workload is too great for him to bear, and he is too late in time, and these tools they have are not of much use, this is indeed a problem.

"Now I'm kind of nostalgic for those, if I can make a dust explosion, maybe I can blow the tunnel out." Wang Chengyuan braved the cold air and came over to fiddle with it a few times, but the Xuan Bing did not move at all, not even a scratch was left, if it was really a strange thing, he had to sigh helplessly.

Speaking of those ghost things, Yun couldn't help but shudder, he who had recovered his electromagnetic power was the peerless delicacy of the ghost meteors, and he didn't want to be chased by these things anymore.

"If it is detonated here, it is estimated that we will be the first to die, although the hardness of this thousand-year-old Xuan Ice is not much inferior to steel, but it still has a fatal weakness, it depends on the ability of the dumb." Yun Li thought of a plan and said unhurriedly.

"Dumb?" After Yunli said this, Wang Chengyuan and the dumb man were confused, and they broke into the ancient tomb all the way down, and the leader was either Yunli or Wang Chengyuan, and the dumb man was a supporting role, not to mention that his current state was much worse than Yunli, and it was unrealistic to rely on him to break the ice.

Yun Li knew their doubts, so he immediately explained: "Brute force can't work, we can take advantage of it, the weakness of this thousand-year-old Xuan Ice lies in resonance, we create a sound wave similar to its natural frequency, it is estimated that we can crack it from the inside, and the dumb bamboo whistle is just right for using." ”

The principle of this method is very simple, but how to blow the required frequency sound waves, this may be more difficult than smashing with brute force, and it is impossible to distinguish it by the human ear alone, but there are clouds among them, and this whimsical method naturally has the possibility of turning into reality.

Wang Chengyuan and the dumb man didn't know that Yunli was using electromagnetic force to sense the frequency of sound waves, but they trusted him quite a lot, under Yunli's instructions, the dumb man began to blow a bamboo whistle, Yunli put his hand on the ice where the channel was located, and used electromagnetic force to sense the effect of sound wave vibration, and instructed the dumb man to adjust the rhythm through gestures, and slowly approached the frequency of resonance.

Wang Chengyuan was not idle, he used the only thing he had to put together a trumpet-shaped thing, carrying it and standing in front of the mute, in order to expand the sound effect, the three of them performed their own duties, and it looked like a bit of a concert, but if the audience could hear the sound of the scene, it was estimated that there would be no one left in the audience.

Yun Li has seen a lot of smashing cups, but this time it is the thousand-year-old Xuan Bing that will be shattered, even if they can find the right frequency, but with this intensity of the whistle alone, the dumb person will not be able to create a crack in the Xuan Bing even if he blows through his lungs, which has to be Yun Li's hand and use electromagnetic force to amplify the sound waves, and with the addition of the two, it is estimated that there will be an effect.

The whistle gradually maintained at a sharp frequency, which was very close to the needs of resonance, and the mute could last for about a minute at a time, and it could continue after a half-minute break, so repeated application, coupled with the assistance of the increase of electromagnetic force, a slight light gradually appeared inside the thousand-year-old Xuanbing, and everyone knew that this was a phenomenon caused by cracks, so they worked harder.

After getting it for a long time, the whole piece of Xuan Ice was already full of cracks, and the three of them were all tired after doing this, the dumb trachea was not smooth, Wang Chengyuan's ears hurt, and Yunli was too much electromagnetic consumption, but they didn't mean to stop and rest, and continued to work hard.

The impact of the fragmentation of the thousand-year-old Xuan Ice is that the temperature in the secret room has plummeted, and it has been unable to keep the cold astringent, even if the three of them are fully clothed and equipped, they are still shivering from the cold, the temperature here is much lower than in the ice and snow, and the cold is approaching the body, Wang Chengyuan and the dumb man are deeply affected, it is estimated that it will not be long before they become two popsicles.

Yun Li knew that he couldn't drag it out any longer, and the thousand-year-old Xuan Ice was almost on the verge of collapse, so he accumulated the green ox and broke the Xuan Ice in front of the passage with one kick, revealing a square entrance.

As soon as the passage came out, the dumb man and Wang Chengyuan immediately put away their backpacks and climbed in, this passage was too narrow, adults couldn't stand up in it at all, they could only use crawling, the snow wolf dog was just right, and they didn't have to lower their heads to walk in front, before leaving, Wang Chengyuan was not busy reminding Yunli to take the bronze long sword away.

Yun Li didn't plan to take the bronze long sword, after all, he had already obtained the Ice Plum Blossom, and the weight of this bronze long sword was not light, and the cold aura of his body did not disperse, which had a lot of interference effect on his electromagnetic power, and it was a burden to carry it, and I don't know what difficulties would wait for them on the road, it was not a wise move to take it with him, even if its value was definitely not low.

What's more, he even broke the thousand-year-old Xuanbing that others used as coffins, and it seemed a little unkind to take the sword that accompanied the funeral, although he had no prejudice against the act of robbing the tomb, but if he really wanted to do it himself, he still had some scruples. But thinking that the owner of this tomb set up so many mechanisms to torture them, and almost died here several times, it is not too much to take this bronze long sword as a comfort, not to mention that when this ancient tomb was built, the owner of this tomb must have done a lot of things that hurt the heavens and reason, so Yun Li's heart was calm.

After climbing for a long distance, the passage began to widen, they could bend over and walk, but this walking posture was also a tiring job, they stopped and stopped, they didn't know where the passage was going, and this passage was not like those in the tomb, there was almost no light, they could only move forward in the dark, and the air was thin, if it weren't for their oxygen bags, it was estimated that this road would not be able to walk.

The darkness is not an obstacle for Yun Li, he is the first to take the lead, Wang Chengyuan is in the middle, the dumb and the snow wolf dog are behind, the three of them and a dog go all the way down the passage, occasionally encounter a collapse and blockage, fortunately it is not very serious, the three of them can continue to move forward after a while, there are no difficulties along the way, it seems that this is really an escape channel left by the craftsmen.

The front section of the passage is dug out in the belly of the mountain, and most of the back section is a natural rock crack and crack, the space is larger, but it is rugged and difficult, if it is not for the instructions of Yunli to lead, Wang Chengyuan and the mute will definitely suffer a lot in this place where they can't see their fingers. Yunli guessed that the craftsmen had discovered the existence of this rock crack and combined with the location of the blind spot of the five coffins, so they would build the escape in this place.

The water and food are exhausted, they are still moving forward in the dark, stop and rest when they are tired, lie down and rest when they are sleepy, so even the spare oxygen bag is estimated to not last long, and they can reach the center of the earth if they go down, Yun Li just wanted to stop them to rest for a while, but there was gratifying information from the outside consciousness, and immediately reported to the two of them:

"The exit is not far away, hold on a little longer!"

These words were injected into the bodies of the two like stimulants, and even the snow wolf dogs cheered up, and everyone unconsciously accelerated their pace. Sure enough, it didn't take long for them to see the light they hadn't seen for a long time, and they didn't care about the discomfort caused by the lack of light for a long time, so they ran quickly to the exit.

"Snow wolf dog, come back! Dumb, hurry up and stop the snow wolf! ”

After seeing the exit, the snow wolf dog was so excited that he got carried away, and he ran out with his legs, Yunli reacted and wanted to stop it, but it was too late, so he immediately pulled the dumb man over and asked him to whistle.

The whistle of "whirring" sounded, the snow wolf dog slowed down a little, and just stopped at the exit, the three of them hurriedly ran over, Wang Chengyuan and the mute man understood why Yunli had to stop the snow wolf dog urgently, because outside this exit is an almost vertical rock wall, and below is a desolate valley, if you fall down, there will definitely be no way to live.
