"It's not that we didn't think of using explosives to blow it up, it's just that it's easier said than done, and we're still working on it. There are three main difficulties: First, because it is close to the military base, I am afraid that it will affect the base's armament equipment, and even some high-power weapons......" Chen Langping said high-power weapons, deliberately lowering his voice.

Fang Tianyou and the others did not ask what kind of high-power weapon it was, which involved state military secrets. Anyway, those things can't be detonated.

"Second, we should consider the collapse caused by the explosives, and third, we should consider whether the explosives will blow up the contents of the tomb, after all, some of those pills and other things will deteriorate as soon as they are exposed. Chen Langping continued.

"It's so complicated, no wonder it's been so many days, and it still hasn't been dug yet. An Yan sighed, "Since we are here, we might as well go down and have a look first, maybe there is something to discover." ”

"Of course, I asked you to come to think of a way to come up with ideas, otherwise you will be allowed to watch the play alone. Chen Langping scolded with a smile and reminded, "However, if you really open the stone door, you must also be careful, don't rush in, according to the advice of tomb robbers and archaeological experts, there is likely to be poisonous gas in this tomb!"

"Poison gas!" Fang Tianyou and the others were shocked when they heard this.

"Although the technology of ancient people was not as good as that of modern times, poison gases were diverse, so even if you are good at kung fu, you must be careful. Chen Langping reminded.

"Okay, we'll be careful, besides, it's not certain if we can open the stone door. An Yan replied.

Under the guidance of Chen Langping, An Yan took Fang Tianyou and Gong Xi to the entrance of the ancient tomb, which was an underground passage that sloped downward.

Although the engineers had excavated in the early stage, the passage had been widened, the ground had been paved, and wires had been pulled, and electric lights had been installed at intervals at the bottom of the cave, but after entering the passage, the three of them still felt a chill.

With the help of the not very bright light, they walked forward for a long time, and the three of them really saw a stone gate standing there in front of them. There are some quaint characters carved on the stone door, which look very ancient, but Fang Tianyou and the three of them don't know each other.

An Yan stepped forward and tried to push the stone gate, but found that the stone gate did not move at all, he increased his strength again, and later Gong Xi simply pushed together, but still did not feel the stone gate react.

"This stone gate is really not simple. An Yan shook his head and gave up the idea of pushing it away.

Fang Tianyou wanted to use his divine sense to probe the inside of the stone gate, but found that his divine sense could not penetrate this stone gate. Fang Tianyou's current divine consciousness can detect 100 meters on the ground without hindrance, and it can also detect 40 or 50 meters in the sparse soil layer.

But now it is impossible to detect this stone door. It can be seen that the stone of this stone gate is hard and dense, and it can also be inferred that this stone is huge, and the thickness should be at least ten meters or more, which isolates Fang Tianyou's divine sense detection.

"If you want to open the stone gate in front of you with brute force, it will be very difficult. Even if explosives are used, ordinary explosives will not work. If there is less explosives, you will not be able to blow up the stone door, and if there are too many explosives, you will be afraid of adverse consequences. Fang Tianyou knocked on the stone door and said.

"It stands to reason that there is usually a mechanism to control the rise and fall of a stone gate like this. Gong Xi said.

"So many masters outside have already studied it, and if there was a mechanism, it would have been discovered a long time ago. I wonder if this is a dead door, and the real entrance is somewhere else!"

"Let's look for it first, if someone else can't find it, it doesn't mean that we can't find the 'Dragon Shield' either. Fang Tianyou said.

"That's right, too. Although our 'Dragon Shield' is not known for robbing tombs, since we have already gone out, we can't admit it so quickly. An Yan said with a smile.

So, the three of them began to search the surroundings, carefully looking for clues.

Although Fang Tianyou's divine sense could not see the situation in the inner layer of the tomb through the stone gate, he could see the surrounding situation at a glance. He soon noticed a palm-sized stone protruding from the right wall of the cave near the stone door.

This stone protruded, and it seemed to be naturally combined with the surrounding soil layer, but Fang Tianyou discovered the strangeness in it through his divine sense. The stone is curved, like a deadbolt with two ends upturned, and if you press it down, you should be able to activate a certain mechanism.

Fang Tianyou tried to press the protrusion, but found that the stone did not react at all, so he gradually increased his strength. Until he used all his physical strength, he was still unable to defend the stone. The stone seemed to have taken root, and it did not move.

"Maybe it's a stone that grows here in the sky, embedded in the earth, where can you press it. Gong Xi saw Fang Tianyou struggling with the stone, and reminded with a smile.

"No, I don't have a problem with this stone at all. Fang Tianyou insisted. As he spoke, he took a few steps back, secretly operated the true element, and then with acceleration, quickly approached the stone, and swung his right palm out heavily, pushing it on the stone.

"Boom......" There was a heavy sound from the stone door, as if something had been pushed open.

"There's a play!" An Yan said in surprise. But after waiting for a long time, except for that bang, Shimen did not react anymore.

"No, there was a reaction in the stone gate just now!" Gong Xi said puzzled.

"You push the stone door again. Fang Tianyou probed with his divine sense, and clearly "saw" something at the bottom of the stone gate burrowing into the ground, as if it was something similar to a door bolt.

In the case of opening the door, even if it is not an automatic door, since the deadbolt has been opened, it is enough to push the door open. The problem now should be that the stone door itself still has weight, and it is not something that ordinary people can push open.

When An Yan and Gong Xi heard this, they pushed the stone gate again suspiciously, and this time they really found that the stone gate moved. The two pushed harder. Seeing this, Fang Tianyou also stretched out his palm to help push it.

"Ge Bang," the stone gate came out with a roar, and began to retreat towards the inside, one centimeter, ten centimeters, thirty centimeters, the three pushed more and more smoothly, the stone gate retreated faster and faster, and soon, I was afraid of a "boom", the stone gate seemed to hit something, and stopped.

However, on the right side of the two-meter cave wall left behind the retreat of the stone gate, a one-person-sized hole was revealed. At the same time, a breath of air that could not be said to be fresh came out of the cave.

"The stone door is open!" said the three of them with a smile on their faces. An Yan immediately took out the special walkie-talkie of "Dragon Shield" and reported the good news to Chen Langping.

Chen Langping was also happy in his heart, and immediately began to arrange further excavation activities.

Fang Tianyou in front of the stone gate did not wait for Chen Langping's response, turned on the searchlight he brought with him, and walked towards the entrance of the cave that had just appeared, and Gong Xi also followed curiously.

The cave was small and short, as if it had bypassed the stone gate and turned back to a passage about the same width and height as outside.

Gong Xi was about to walk forward, but Fang Tianyou stopped him. Then he picked up a piece of gravel in the corner next to him and threw it in front with all his might.

The stone "snapped" and rolled forward, and Gong Xi was puzzled, but heard a large number of arrows shooting from the stone walls on both sides.

Seeing that Gong Xi and An Yan, who had just walked in, both had a chill behind them. If this is shot directly on people, it will not be directly shot into a hornet's nest.

Fang Tianyou seemed to have expected it, and only after the arrow was fired did he step on the passage inside. When Gong Xi and the others saw that he had passed safely, they also followed his steps and walked all the way, passing through this passage full of arrows.

"There's an agency inside, and it's best for the general staff not to come in now. An Yan reported to foreign exchange through the walkie-talkie.

The three of them walked out of a distance again, and another stone gate appeared in front of them, but this time the stone gate was not as thick as the previous one, and Fang Tianyou's divine sense could detect it through.

Through the stone door, Fang Tianyou "saw" that there was indeed an open space inside, although he couldn't see the coffin and other things, he should also be able to infer that this was inside the tomb.

In the space inside, because of the limited detection distance, Fang Tianyou didn't see anything, but under the space, Fang Tianyou found an underground stream, which seemed to be a small underground river. The water of the dark river is silvery-white, and a faint white mist rises from time to time on the surface of the river.

"It's not a stream, it's a ditch dug by hand, and the silver-white thing is not water, but mercury, and once it is volatilized, it has highly toxic mercury. Even if it is buried under the soil, there must have been a lot of evaporation to the ground over the years. There is only fear of poison in the tomb space!" Fang Tianyou was secretly shocked in his heart. He can now carry out internal breathing, and he doesn't have to be afraid of the poison of these mercury, but An Yan and Gong Xi are not in a good situation.

"I suspect that there is poisonous gas in it, so you should ask General Chen to arrange for someone to come with gas masks and oxygen. Fang Tianyou reminded An Yandao.

"He had already thought of this when he was talking to the boss just now, and now he has probably sent someone to send it to us, so let's wait for someone to go in later." An Yan said.

In this regard, Fang Tianyou didn't have much to say, it was of course the best not to expose the secret of his inner breath, not to mention entering the grave, and he was not in a hurry at this time.

Fortunately, the people outside are also fast enough. Within minutes, gas masks and oxygen were delivered. Due to the accident of the three people, in addition to the three special police officers who sent things in, a Taoist priest and a monk followed.

Someone in the special police took out a certificate, and An Yan took it and confirmed that it was commanded by Chen Langping, and the two sides were connected. Fang Tianyou and the three of them each received a set of gas masks and oxygen supply equipment from the special police.

Fang Tianyou was wearing the equipment while secretly looking at the monk. He found that the monk was fine, his breath was quite thick, but on that Taoist priest, Fang Tianyou always felt a cold aura, and he couldn't help but be secretly vigilant.
