This black gate, about two meters high and one and a half meters wide, has a cold and smooth tentacle, with a metallic feel, and in terms of shape, it is actually very ordinary.

However, when this ordinary gate is located at a depth of hundreds of meters underground, it is not only ordinary, but has a strange and eerie feeling.

Looking at this gate, after the three of them glanced at each other, Liu Jizong took out two pills and handed them to Ye Dong and Red Wolf respectively: "You guys should replenish the aura first!"

Although Liu Jizong helped absorb the water in the soil that passed down this way, although Ye Dong restored his original appearance in order to save aura, the aura consumed by him and the red wolf was still very amazing, and he was about to open this door, and he didn't know if there would be any danger hidden behind the door, so they had to let their aura recover as soon as possible and deal with any possible accidents in the best condition.

Ye Dong and the red wolf were not polite, and took the pill and swallowed it separately.

Although Liu Jizong was not an alchemist, as the younger brother of the previous sect master of Cihang Sect, the pills on his body were naturally extraordinary.

As the elixir turned into liquid and flowed directly into the lower abdomen, the huge aura filled Ye Dong and the red wolf's bodies almost instantly.

While the two of them were busy digesting the effects of the medicine, Liu Jizong and Liao Yue were not idle, and they tried to peek behind the door with their spiritual senses to see if they could find anything.

However, it is a pity that the spiritual senses of the two of them, regardless of strength or weakness, will be immediately shocked by a powerful force when they come into contact with the black door, as if there is an invisible cover around this door.

Liu Jizong shook his head and said, "This door has been forbidden by a master, and our spiritual sense cannot penetrate it. ”

Liao Yue nodded silently.

After a while, Ye Dong and the red wolf recovered one after another, and after everyone looked at it again, Ye Dong put his hand on the door, took a deep breath, and with a slight force, the door was slowly pushed open!

Behind the door, there is no imaginary Huangquan guide, just a narrow passage, about two meters high, at most can only allow two people to pass side by side, there is no sky, and there is a night pearl the size of a dragon's eye hanging on the walls on both sides every other distance, releasing a soft and bright light, illuminating the whole passage with a piece of light.

The passage is inclined downward, and it is impossible to see where the passage leads with your eyes.

Liu Jizong looked at the night pearls hanging on the wall, and snorted coldly: "It's really a big deal, I actually used the night pearls as lights." ”

Indeed, these night pearls, any of which are sold for a great price, are now placed in this narrow passage to serve as illumination.

Ye Dong's attention was not on the Night Pearl, but he was busy using his spiritual sense, wanting to follow this passage to see if he could find anything.

Although his spiritual consciousness was not shocked back by any force, it could only be released to a distance of more than two meters, and once it exceeded this distance, the spiritual consciousness would automatically disperse.

Obviously, even though it was just a passage, it was still manipulated and forbidden to prying eyes.

Since the spiritual sense had no effect, Ye Dong simply gave up the exploration, everyone was here, what else was there to be afraid of, so he stepped into the door first and stood on the passage.

Liu Jizong, Liao Yue and Red Wolf naturally followed.

"Ye Dong, let's take the lead, Liao Yue, you and the red wolf are postponed. ”

For Liu Jizong's words, everyone had no objections, so they divided into two groups, and just walked a few steps forward, the black door behind him suddenly slowly popped back, and the "click" sound seemed to be locked, and all this seemed to be operated by someone in secret.

Liao Yue turned around, walked to the door, and said after pushing and pulling a few times, "I can't open it." ”

"Let's move on!"

Ye Dong didn't care about the door closing, he believed that there must be people living here, so there must be a way to leave.

So the group continued to walk forward, and came to the end of what they had just seen, and sure enough, the passage was extending to the bottom of the road, and there was still no end in sight.

After walking along the passage for nearly a quarter of an hour, except for the passage that was still with no end in sight and the night pearl on the wall, no anomalies were found, as if the road was endless, and there was no end at all.

Liu Jizong couldn't help but whispered: "Now we have probably gone two or three hundred meters underground, how deep are these people hiding, and how did they build this passage." ”

A hundred meters underground, it began to continue down, building a passage one or two hundred meters deep, which is not something that ordinary people can do.

Another quarter of an hour passed, and Ye Dong suddenly let out a sigh of relief and said, "The front should be at the end!"

Sure enough, everyone walked two meters further, and the slope of the passage began to slow down, just now it was a flat road, and after turning a corner, they finally saw the entrance to the cave.

Everyone quickened their pace and rushed to the entrance of the cave, but at the moment of standing at the entrance of the cave, the three people and one wolf couldn't help but be stunned in unison.

In front of everyone is a huge square, in the middle of which stands a huge stone tablet about five meters high, on which are written three blood-red characters - Yin and Yang Realm!

Passing through the square, you can see a flat road, stretching into the endless distance, and the two sides of the road are actually planted with a kind of fiery red flowers, competing to bloom, enchanting and gorgeous, but giving people a creepy and strange feeling.

The passage hundreds of meters long just now was enough to shock Ye Dong and the others, but compared to such a spectacular situation in front of them, that passage was not even a fart.

Liu Jizong's mouth opened wide, and finally he couldn't help but curse a dirty word: "Damn, don't tell me, this is really the underworld!"

How much manpower and material resources are needed to build such a large-scale world realm in such a deep underground?

Looking at the spectacular scene in front of him and listening to Liu Jizong's words, Ye Dong remembered the Danfang Cave on the Tiandan Peak in the Tianxin Sect for no reason.

At that time, he was also shocked by the grandeur of the cave, originally he thought that it was created by the predecessors of the Tianxin Sect, but later learned that the cave actually existed before, and according to analysis, the cave should have been built by a strong man with his own strength.

So, is it possible that this magnificent underground world in front of you is also from the hands of a certain strong man?

Maybe this idea does sound incredible, but it's not impossible, like yourself and others can go 100 meters underground, to ordinary people, isn't it also incredible?

The gap in strength will naturally limit your horizons and ideas!

But now is not the time to explore these questions, Ye Dong slowly walked under the stone tablet, looked up at the three big characters of "Yin and Yang Realm", and said with a cold smile: "Stepping through this stone tablet, does it mean stepping into another world?"
