"Of the three holes, which one do you want to choose, and this is obviously a hole made by an animal, aren't you afraid that there will be danger inside?" Zhang Tianyuan asked cautiously.

Now this situation is obviously an accident, but everyone is not in a hurry, because such an accident is expected, after all, this palace under the sea has moved, and there will definitely be a collapse.

The question is just which of the three holes to choose.

"Take this one on the left. After observing the three holes, Yang Yijun quickly made a decision.

Zhang Tianyuan wanted to ask why, but after thinking about it, he gave up, he estimated that Yang Yijun was also blind, even if he asked the reason, Yang Yijun must be talking nonsense, then it was better not to ask, just try it first, if you can't get in later, you can come out, anyway, there is plenty of oxygen.

When it comes to oxygen, I have to praise Liu Ruohan, these oxygen cylinders she provided are all works under first-class technology, and they were originally only used by the frogmen in the army, and the people can't buy them if they want to, and the quality is surprisingly good.

It seems that Zhang Qisheng is not bad in the United States, otherwise he would not be able to get this kind of thing.

Everyone entered the cave, but because it was a hole made by an animal, it was definitely not as suitable for people to move in as it was to rob the hole, and some places were too narrow, and they had to be re-excavated, so this job could only be handed over to Liu Ruohan, who was walking in the front.

At this time, the original formation had been disrupted, because the cave could only accommodate one person, and Liu Ruohan was at the forefront. Next is Yang Yijun, then Zhang Tianyuan, and Haiyu. Brother Pony is still in the end, but Brother Pony doesn't know how to develop a bad habit. It turned out to be backwards, and I don't know how he confirmed the distance between himself and the sea fish, anyway, after walking and stopping, he didn't even encounter the sea fish.

It looks like this guy really looks like a master of sea fishing.

The cave road twists and turns, while moving forward, while digging and widening, so everyone is moving very slowly, but fortunately, the position from the entrance of the cave to the gate is not far, so after a distance of more than ten meters. Everyone's eyes suddenly brightened, and they saw the light again from the darkness.

Although the light is only for the inside of the cave, it is still a little dark, just like when the sky is about to get dark, after all, this is still in the sea, although it is not far from the sea, but the light can always shine down.

"This is the gate?" After exiting the tunnel, everyone breathed a sigh of relief that nothing had happened. This is the luckiest.

Zhang Tianyuan looked at the door in front of him, looking at the material, it should be bronze, but it is not bronze from the Shang and Zhou dynasties or the Qin and Han dynasties. Rather, it is an alloy that is closer to modern times.

"Yes, this is the door. Haiyu nodded, and then took out his three small bronze mirrors.

"It turns out that there is no water here. But now it's filled with seawater, so it seems. I guess the environment has changed a lot, so I hope the mechanism hasn't failed. He spoke. walked over and put three small bronze mirrors on the keyhole, and then said to Zhang Tianyuan: "Boss Zhang, bring your big bronze mirror." ”

"You should go to Miss Liu, I believe she has the real thing in her hand, this one in my hand is an imitation, and something will happen if you don't get it right." Zhang Tianyuan guessed that since Liu Ruohan was sure to come to this palace under the sea, he didn't even ask him if the bronze mirror was real, which means that Liu Ruohan probably had a real mirror in his hand.

Moreover, Liu Ruohan and her master Zhang Qisheng often poured sea buckets, this place, they must have been here, maybe not in depth, but like sea fish, the possibility of obtaining a bronze mirror is relatively large. Otherwise, it is unlikely that the imitation bronze mirror will appear on the market.

Even Zhang Tianyuan suspected that Zhang Qisheng might have something to do with the Heavenly King and Mo Xie.

The workmanship of the imitation bronze mirror is the characteristic of the Hidden Heavenly King, Zhang Tianyuan recognized it at a glance, and it is not clear that Zhang Qisheng and the Hidden Heavenly King are still old friends.

As for Mo Ye, that was pure speculation. Because Zhang Tianyuan could confirm that he had not offended Liu Ruohan, let alone offended her master Zhang Qisheng, what was the reason for Zhang Qisheng to want his life? After thinking about it, he still blamed the suspicion on Mo Xie.

If Mo Xie is Zhang Qisheng's apprentice, this qiē makes sense.

Of course, this was just his guess, and he couldn't be completely sure, but he didn't think he could be wrong.

There is no love for no reason in this world, and there is no hate for no reason.

Because the channels of the walkie-talkie are all public, Liu Ruohan also heard Zhang Tianyuan's words very clearly. She glanced at Zhang Tianyuan with some surprise, obviously surprised that Zhang Tianyuan could think of this.

But surprise to surprise, she took out the large bronze mirror and put it on the keyhole.

With the insertion of the large bronze mirror, the door suddenly came loose, but it did not open automatically, only slightly opening a gap.

"It turns out that the story is all deceitful, and there is no such mechanism at all. Zhang Tianyuan smiled bitterly.

"The trap door in the game never tells you what the principle is. Actually, there is no need to design that thing, as long as the lock is opened, then the door should be able to be pushed open. Liu Ruohan smiled, then raised his hand and pushed the gate open with the sea fish.

Although the door is very heavy, because the design is more reasonable, as long as the lock is opened, even an ordinary woman can easily push the door open, which can be regarded as a kind of mechanism. It's rare that it hasn't broken down after so many years.

"Be careful!"

After the gate was opened, the sea fish raised his feet and walked inside, but was dragged by Zhang Tianyuan's timely reach, because he didn't know which immoral ghost did it, and he actually dug a big pit behind the gate, although he didn't know how deep the pit was, but he saw that the surrounding sea water was poured into it, and he couldn't fill it for a long time, so he knew that it would definitely not be shallow.

"Thank you, Boss Zhang. "The sea fish looked at the big pit of the black hole below, and didn't know what it was down there, but if it fell, it was estimated that it would be nine deaths, even if there was water below, it would definitely fall and be seriously injured.

"Look, there's still a wall behind this gate, and you can't get in at all, so it's no wonder someone is digging a hole here. At this time, Liu Ruohan's searchlight was already shining behind the gate, and the distance was very close, but three or four meters away, there was a thick and tall wall, and there was no roof visible on it.

"What the hell is this building, it's so weird. "Brother Pony doesn't have a good air.

"It looks like we can only go down to the pit through guò. Zhang Tianyuan thought about it, so he took out a nylon rope and tied it directly to the bronze gate outside, and tried to pull it, there was no problem, this rope was very strong, and it was not a problem to bear something weighing three or four hundred catties.

"Who's going down first?" asked Haiyu.

"I'll do it. Zhang Tianyuan had already seen the situation below, because there was no obstacle, so he looked far away, there should be a river below, there was no water around the river, after the sea water poured down from here, it flowed away, and next to the river, there was a brick floor, which was obviously made of artificial masonry, which made him a little strange, obviously set the gate here, but under the pit nearly ten meters deep, there were still such artificial traces, this palace looked more complicated than imagined.

He observed it and confirmed that there was no danger below, so he volunteered, and this first one went down, and no one could stumble, relatively speaking, it was much safer.

At this time, everyone did not argue, they all had to go down anyway, and it didn't make a difference who went down first, but Haiyu was a little worried, after all, in his opinion, the reason why Zhang Tianyuan came to take the risk was purely because of his invitation, so he wanted to go down first.

However, Zhang Tianyuan had already arrived in the pit, and it was too late for him to stop him.

The helmets they wore that completely covered their heads had a searchlight on them, so they could clearly illuminate the road below.

The helmet is not bulky, because it is not made of metal, but uses lightweight, high-tech materials, which are not only strong, but also lightweight, which is worth a lot of money.

As the distance got deeper and deeper, Zhang Tianyuan saw the situation below more clearly, there was still a wall below, but there was a hole in the wall, obviously when someone came in, they encountered the same situation, so they used the method of stealing the hole and entered it.

He reached the bottom, untied the rope from his waist, and then used the guò walkie-talkie to give a brief introduction to the environment below, and even tried to light the fire fold to confirm that the fire fold could continue to burn, which showed that there was oxygen underneath.

So he simply turned off the oxygen cylinder, after all, although this oxygen cylinder can provide a lot of oxygen, but the time is limited, and it is better to save as much as possible.

However, he didn't take off the helmet, the helmet comes with a gas mask, which can filter toxic substances in the air, and it also comes with a communication function, which will be very troublesome to remove, and more importantly, this thing is sturdy, in case of danger, it can save his life.

After everyone above confirmed that there was no danger, they all went down in turn, and although it was not comfortable to be constantly watered by the seawater, they all felt a lot more relaxed after getting to the bottom.

This person is really more reliable standing on land, and even if he is wearing a wetsuit in the water, he will feel uncomfortable.

"What kind of principle do you say this, after the sea water flows in, it won't fill this place, and then flow out again?" After seeing the situation inside, Zhang Tianyuan couldn't help but feel a little curious, this kind of design is really too exquisite.

"No matter what you're doing, we're not here to study ancient architecture, let's summarize the situation first, and then make a new plan. Brother Xiao Ma was bold enough, he took off his helmet directly, took a deep breath and said: "The air is filled with the stench of corpses, I guess, if this palace used to live with living people, now it has become a tomb of the dead."
