When Lin Xia stood up, Li Chengfeng took the lead and walked inside. The cave was extremely dim, and the two had to light candles.

The terrain went all the way down, and when they first stepped on the steps, the two of them seemed to be stepping on something, soft and soft, which made people feel numb.

"This ...... What is this? We can't be stepping on some big snake or insect or something, right?" Lin Xia asked Li Chengfeng with the discomfort in his heart.

The most regrettable thing about "Swordsman" is that there is no olfactory sensing system, after all, this is something that cannot be simulated in the virtual world.

If the two of them could smell the smell at this time, they would probably be so smoked by this fishy smell that they rolled their eyes. The damp, musty air is mixed with a fishy smell, and in such a confined space, even if you don't get poisoned, it will make your heart feel uncomfortable.

As he continued to walk down, the candle flame pierced the darkness and revealed everything in front of him. I saw that the strange stones hanging upside down in the passage overhead were covered with dense bats, and the candlelight came, boom, thump!

From time to time, there is a faint and eerie sound of wind moaning from the auditory sensor, and there seems to be the sound of rushing water.

It turned out that this staircase was leading to an underground river passing underneath. The dark river and stream are turbulent, and white smoke rises from time to time. The two of them threw a stone and tested the depth of the water. Fortunately, the dark river belongs to the shallow stream type, and the two of them are ready to wade through the water.

As soon as they came into contact with the stream, they felt a warm current lingering on their feet. This dark river is actually a warm stream. It is no wonder that the shallow stream was constantly drifting white smoke and water vapor.

"There should be an underground fire here. We've gone deeper into the secret realm, probably in the middle of a cliff. Li Chengfeng said.

Lin Xia didn't speak because he was nervous, but just followed closely behind Li Chengfeng with a candle.

The more the two of them walked inside, the more they felt the heat, and the oncoming heat wave couldn't help but remind Lin Xia of the summer in the mountain city. Bursts of hot wind kept blowing. Lin Xia didn't know whether it was because of nervousness or heat waves, and fine beads of sweat had appeared on his sideburns.

As I walked down the terrain, the front became more and more red, as if someone was burning a fire in front of me.

Suddenly, the two of them were caught off guard, and what appeared in front of them was a huge circular pagoda-like building, the pagoda was located on top of a ring, and the ring was surrounded by fiery red magma, and the magma was constantly churning and rolling upside down. From time to time, a drop or two of fiery red solution was squirted.

I saw that both sides of the ring were stained with gray-white cooling residue.

"Leyline Fire!" Li Chengfeng said in a tone that seemed to be full of incredulity.

"What is this?volcano?" Lin Xia asked curiously.

"It can be said to be volcano, but it is not volcano. It's just a bare place in the center of the earth! But it's enough to show that we've gone from a cave in the middle of the mountain to the bottom of the mountain!" Li Chengfeng said in a complicated tone.

"Your sword hiding is really a big skill, and it is surprising every time. Tiankeng Village, the fire in the center of the earth. I really don't know how magnificent your Hidden Sword Villa should have been when it was in its heyday!" Lin Xia sighed as he looked at the scene in front of him.

"Although the fire in the center of the earth is extremely difficult to find, it is said to be relatively common on the coast of the East China Sea. On the other hand, the circular pagoda here is really admirable. Li Chengfeng said.

"It takes a lot of strength to build a three-story pagoda in this molten land, and it takes a lot of strength in addition to the magic of skill. The two couldn't stop sighing.

"Then why did you build the pagoda on the fire of the leyline?" Lin Xia asked curiously.

Li Chengfeng smiled and explained: "This secret place may be relatively old, the Tibetan Sword Villa was once located on the shore of the West Lake in Lin'an City, and it has been famous for forging swords for generations. All the famous swords in the world come from the Tibetan Sword Villa, which is also the origin of the name of the sect. ”

Li Chengfeng continued to talk to Lin Xia. How did such a great martial arts sect go into decline and perdition? The world is impermanent, and prosperity is bound to decline. At that time, there were disputes in the world, but the weapons of the people in the world who killed each other came from the Tibetan sword. The owner of the village felt deeply guilty, so he stopped forging swords, and began to study advanced swordsmanship.

But it also offended a lot of forces because of this, and at the same time, the study of swordsmanship is not a matter of one or two days. The Tibetan Sword Villa has lost the most important sword, and the prestige of martial arts has also been lost.

When the position of the villa is passed on to the next owner, the husband is not guilty and is guilty. People all over the world began to covet the various famous swords in the Tibetan Sword Villa. For this reason, the owner of the village began to bring some weapons here to build this secret realm, in case the hidden sword was broken.

"How do you know this?" Lin Xia suddenly asked.

"Look, it's written on the stone wall. Li Chengfeng said with a smile.

"This leyline fire was found by the owner of the village to be used to forge weapons for the Tibetan sword disciples who were hiding here. Li Chengfeng said.

"Then why is the secret realm still in decline here, and what about the hidden sword disciples here?" Lin Xia asked again.

"I'm afraid...... The ancestors built this place back then, and before the disciples of the Tibetan Sword Sect could transfer here, something happened, otherwise why hasn't the top of the pagoda here been repaired?" Li Chengfeng said.

"Then what inheritance can there be if it hasn't been repaired here?" Lin Xia said.

"Have you forgotten what the county keeper said? This is what my master handed over to him for safekeeping, so the inheritance is my master's inheritance. Li Chengfeng said.

"Oh, I see. Your master also found this secret realm of the hidden sword back then, and then he left this inheritance and passed it on to the descendants of the hidden sword, that is, you. Lin Xia suddenly realized.

Then the two of them began to circle around, looking for any writing or murals on the stone walls, or the secret chamber of the machine. But nothing came of it.

However, Lin Xia found a small white flower on the stone wall, but he had not learned to collect medicine and make medicines. Just by feeling that this should be a precious medicinal herb.

Later, Lin Xia found several ores under the stone wall. There are copper mines, basalt mines, and fluorite mines. Among them, only copper ore can be mined at the current mining level of Linxia.

Lin Xia dug up in the corner, and also dug up a lot of associated ore sulfur ore. I don't know what the use is, but Lin Xia took it one by one.

"Li Chengfeng, why are all the Xuanwu mines here broken?" Lin Xia said loudly.

"What do you mean by that?" Li Chengfeng asked when he heard the sound.

"You see, there is basically a little bit of this basalt left here and it is broken, but the low-grade ore of copper ore has not been destroyed. Lin Xia said.

"Maybe the ancestors found high-grade ore in order to build this place, or the master mined it back then. The more high-grade ores you need to forge a sword, the higher the quality. Li Chengfeng said.

Lin Xia thought about it.

The two of them wandered around for a long time, but they didn't find any mechanism or record. I decided to explore the circular pagoda.
