Zhou De looked at the coffins carefully, there was no handwriting left on them, only a few pry marks, indicating that Li Wanfa seemed to want to open these coffins at that time, but he left without leaving an explanation?

There are still many mysteries at present, and everyone has no time to think about what happened back then, and Li Wanfa's powerful ability is also blocked here, and I don't know what level is here. Nanyang and the others walked to the metal wall with bated breath, looked at the cross flower holes, and were surprised to find that there were faint scratches on the edges of the holes. Where exactly is Levin found?

While everyone was still pondering, the room suddenly shook violently, as if another violent earthquake had occurred, and then a deafening roar sounded. Everyone leaned together, and at the same time there was a strange sound in the room, it was the sound of a jet!

Everyone was shocked, how could there be a jet in the room?! The sound turned into a high-frequency vibration, and everyone immediately felt a splitting headache, and then the sound of the two soldiers fighting on the ancient battlefield echoed in the room, and the sound of the impact of cold weapons was as clear as in front of them, and the shouts of people, the neighing of horses, screams, cries, and angry curses...... Shocking, everyone nervously held their weapons, as if they were standing in the middle of the battlefield, surrounded by the two warring sides fighting and fighting, the shouts of the ancients were very real, and the battle situation was extremely tragic. The sound lasted for about dozens of seconds, gradually disappeared, and suddenly gunshots rang out again, and Nanyang, Qiu Tian and Zhuzi immediately heard the sound of M1 rifles, Thomson submachine guns, MP40 submachine guns, etc., as well as grenades, aircraft bombing, and English and German shouts, the sound of tanks, and artillery fire, as if they were on a modern battlefield.

Everyone was stunned, wondering what was going on here, how did it switch from ancient Chinese fighting to World War II? The sound of the battle quickly disappeared, and the room gradually sounded beautiful and elegant music, including chimes, flutes, guqins and other sounds, Zhou De heard that this was ancient court music, like the emperor enjoying songs and dances in the palace, but this sound also disappeared quickly, followed by a mysterious "da", "da" and "da" sound.

Everyone stood nervously in place, not knowing what was going on, and suddenly there was the sound of waves, torrential rain, and then water, as if it was deep underwater, and there was a strange creature's cry, and suddenly the sound became sharp, and the mountains shook, and then there was a chaotic sound, and someone was vaguely heard shouting "How's the situation?!" Someone replied, "...... There was another earthquake...... The second rescue team has withdrawn...... The first group is still down there, and I don't know what happened" followed by a roar and the sound of motors and mechanical transmissions...... Hell, I still can't get down! I don't know what happened to the expedition! "Commander-in-Chief Xiao, the people of the first group are back!" “…… Report to the command, we only cut the 6th metal door, and the bottom has already collapsed, I don't know if there is a sealed door in front of us""...... Are all the comrades alright? None of them were hurt, were they? "Report, Xiao Liu and Da Gang are all in the lottery, both are minor injuries, no problem, Lao Hei was hit by a stone in the leg, probably a fracture...... Everyone else is fine...... The equipment is all thrown underneath......""...... Good...... Good...... You all have a good rest, these earthquakes are too frequent and strong...... Comrades, don't take risks, wait for the earthquake to stop and continue to rescue ......" "Can ...... But...... The experts are still buried underneath...... Commander-in-chief, let's rush again! ”

The voice disappeared vaguely, and the room became quiet again, but after everyone heard this voice, they were very nervous and surprised: among the people who spoke just now, the voice of the commander-in-chief was obviously Mr. Xiao Gang, that is to say, this conversation was transmitted from the ground, and those people seemed to be standing in this room, but they didn't know if this conversation was just said or what was said before. Everyone thought: From this point of view, the troops on the ground have been carrying out rescue work and want to come down to rescue everyone, but it seems that they are blocked by some closed metal door, and they have not been able to open the way.

Nanyang frowned, and said puzzledly: "Strange, when we came down, where were there more than 6 metal doors?" ”

Zhou De thought for a while, then suddenly raised his head and said, "Could it be the staircase at the beginning?" ”

As soon as everyone heard Master Zhou's words, they immediately thought of the long staircase that spiraled down, and Xu Ming said nervously, "...... Difficult...... Could it be that there is a hidden mechanism there that cuts off the passage between the inside and outside of the ancient ruins? ”

Zhou De said anxiously: "It seems that the mechanism for closing the ancient tomb has already been designed there, we only saw the last gate at that time, and we thought that there was only one door there to block the road, and it was easy to be opened, but that section of the ladder has a total of nine layers, which means that there are actually nine gates to close the ancient tomb." ”

Nanyang nodded and said: "With the equipment of the ground troops, it took so long to open only 6 of them, and they have not yet reached the ancient city, it seems that the structure of the ancient ruins and the metal sealing gate must be very strong." In addition, the space of the staircase is very narrow, which is not conducive to the work of quickly breaking through the obstacles, and there have been several earthquakes in a row just now, and the rescue work of the ground troops is very difficult and the progress is very slow. ”

However, when everyone "contacted" the people on the ground, knowing that the troops above had been working hard to carry out the rescue work, everyone's hopes in their hearts were greatly increased, and their spirits were much better.

At this time, the pillar tried the communicator, and there was a strange noise inside, and he said, "Hey, the communication signal can't reach here, how does the sound on the ground come down?" And what were those weird sounds at the beginning? ”

"It's probably an electromagnetic phenomenon, and the strange magnetic field effect may send some signals here, which has been scientifically proven," Gao Qin said. ”

Xu Ming said: "Yes, yes, there are many places that circulate haunted legends, such as shouts or phantoms of the ancients during thunderstorms, in fact, the local weather conditions are more peculiar, there are thunder and lightning or other climates to form a unique magnetic field, the sound and image at that time are recorded, and when the same environmental situation appears in the future, it is released again, just like a videotape." The sounds just now may have been recorded by nature under some special circumstances, and the earthquake here happened to produce a mysterious energy field, so the sounds that happened in the past were restored here. ”

At this moment, there was a strange sound in the room again, as if some kind of instrument was working, and then suddenly there was a screaming and wailing of countless people in despair, the sound of a great wind, which sounded chilling, and then the sound disappeared, and then there was a loud and piercing chaotic sound, as if the end of the world was over, and there were screams of despair everywhere (in the languages of many countries), followed by a deafening roar, as if the sky was falling apart.

At this moment, the room shook violently again, and everyone stood unsteadily, and they all crawled on the ground, and the surroundings suddenly fell silent, and those strange sounds came to an abrupt end.

The vibration quickly stopped, and the red lights in the room suddenly brightened, as if they had reached the highest level of alert effect, and at the same time, the black fog in the room seemed to be rapidly withdrawn, becoming less and less, only to see the coffin engraved with "Xuanwu" suddenly rising from the ground, and there was the sound of mechanism transmission in the coffin.
