Listening to Guo Xiuyuan's explanation, this Fengyang volcano group is built in a connected underground palace. From this entrance, you can walk to every crater at will, and all craters are guarded. Logically speaking, this kind of management It is very strict, no one can sneak in quietly. When it comes to the seal of the Fire Spirit Bird, Guo Xiuyuan can't believe it, because as the deputy leader of the World Business Alliance, he has never heard of the fire in the Fengyang Volcano Group. With the seal of the spirit bird, he couldn't help but wonder if Lu Chen had heard the news from somewhere.

Lu Chen's face was also a little puzzled, and he didn't understand what was going on. Since the guards of the World Business Alliance were so strict, it was reasonable for Han Boyuan to break in silently.

Lu Chen pondered for a moment, recalling the means by which Han Boyuan framed him in Golden Crow City. Everyone in the Luo family believed that he was the one who murdered Luo Zhenyu together with others, and the fact that he saw it with his own eyes showed that there must be someone disguised as himself, only Only in this way can we explain why others insisted that he killed Luo Zhenyu.

This shows that Han Boyuan or Yun Yi are good at disguising.

Thinking of this, Lu Chen immediately asked the two disciples of the guard: "Are you here, no one missing yesterday and today?"

"Missing?" The disciple guarding was stunned, "No one is missing."

"Isn't there any abnormality in the past two days? For example, does anyone of you behave abnormally, and their words and deeds are not the same as usual?" Lu Chen asked.

If Han Boyuan and Yun Yi pretended to be the disciples of the World Business Alliance and broke in, they would definitely not stop, so as not to be seen through, they might go in a hurry, or have other abnormal behaviors. In response to these questions, Lu Chen asked them in detail one by one. .

Guo Xiuyuan and Nie Tianli were standing beside them, listening to Lu Chen's questioning, but they did not interrupt.

However, even such sophisticated people in the world can't help but admire Lu Chen's meticulousness. Lu Chen's questions were very careful and thoughtful.

Sure enough, after a while, the gatekeeper said: "Listen to what Your Excellency said, there is something wrong today. In the morning, two brothers were late for half an hour. They were patrolling near the crater in the south. The two boys have never missed things, and they were late today, and without saying a word, they walked towards the west of the crater, as if they were looking for someone."

Lu Chen said, "The volcano in the west? It should be over there. We'll go over there right away."

According to Lu Chen's idea, Han Boyuan may have killed two people, then disguised himself as the two with Yun Yi, and got in. Only in this way can he break in without disturbing others.

The question is not difficult to speculate, but after asking for a while, I can find a possible clue.

Guo Xiuyuan and Nie Tianli looked at each other, and both walked in with Lu Chen.

The three walked all the way to the west crater.

This underground palace is very spacious, like an underground world, but it looks very hot. All the disciples of the World Business Alliance stationed here have practiced fire-type exercises and are able to adapt to this hot environment.

After walking for more than ten minutes, the temperature is getting hotter and hotter, and it is much hotter than the outside. I am afraid that ordinary warriors in the late Xiantian realm will not be able to stay in this place for too long, unless they are cultivating superior fire such as Lihuo Shen Gong. It is possible to not be affected by this kind of fire spiritual power if the physique is also fire.

For those who practice the Lihuo Cultivation Technique, the fire spirit is strong, which not only has no effect, but is also beneficial to cultivation.

But for most people, being so close to the crater requires body protection profound energy to resist, otherwise it will be unbearable.

Of course, for Lu Chen, Guo Xiuyuan, and Nie Tianli, this level of fire spirit power is trivial.

Of course, there are no disciples patrolling the place that is too hot, and ordinary people cannot resist it, so it is very quiet here.

Not long after they walked, the three saw a well. This was not a normal water well, but a crater. It was used to use the earth's core fire for alchemy, utensil refining, or to practice fire-attribute exercises.

A strong fire spirit emanated from the wellhead, and this temperature was enough to cook the average person in an instant.

However, Lu Chen acted calmly and didn't even sweat.

Seeing that Lu Chen was not affected at all in this environment, Guo Xiuyuan was secretly surprised. Even if he cultivated fire-attribute exercises, it was generally impossible to be immune to fire spirit power, unless the person had a very high level of fire-attribute exercises. attainments.

Although Guo Xiuyuan knew that Lu Chen was an alchemy master who was not weak in Lihuo, but he was so calm and calm, he couldn't help being surprised. Because even him, if he didn't use his skills to resist, he would feel that it was too hot and uncomfortable.

Of course, it was just uncomfortable, and Nie Tianli was the same. With the physical ability of the Primordial Spirit Realm cultivator, this heat could not pose a threat to them.

Lu Chen is indeed very relaxed. This kind of heat has no pressure on him. Since he has cultivated to the Cave Profound Realm, he has already achieved greatness in the art of leaving the fire. The fire attribute profound energy will only be stronger than the fire spirit power of this crater. Naturally don't care about this temperature.

In fact, when Lu Chen was in the Tianlong Continent, he had a brief confrontation with that fire spirit bird, and his body was burned by the spirit fire. It was a fire spirit bird at the peak of the cave, and its flames were very difficult. Burning Lu Chen, the geocentric fire here is naturally nothing.

Near the wellhead, there is a large cauldron, which is the magic weapon used for refining. Below the cauldron, the power of the fire from the volcano can be used.

Item refining is different from alchemy. Alchemy pays attention to controlling the appropriate heat, while alchemy generally requires the stronger the firepower, the better. The stronger the firepower, the easier it is to fuse all kinds of things together, so it needs to be supported by volcanoes. After all, it only depends on the refiner itself. The cultivation base to stimulate the firepower, that is too hard.

It stands to reason that there should be an elder craftsman guarding the furnace near the refining pot, but there is no one here.

"Sure enough, it seems that Han Boyuan has already come." Guo Xiuyuan saw this, and naturally knew that Han Boyuan must have shot.

According to the regulations, there should be at least one elder who refines weapons, plus a few disciples who are responsible for controlling the fire. At least there are two or three people. Now there is no one, not even a corpse.

Guo Xiuyuan's face was a little ugly.

Lu Chen's expression was also solemn, and he said, "The smell is a little off, I'm afraid the body has already been burned by Han Boyuan."

There is an unpleasant smell in the air. In this kind of place, it is easy to destroy the corpse. As long as you kill people with thunder, and immediately use the fire of the earth to burn the corpse, it is difficult to see what is going on.

Guo Xiuyuan naturally understood that things were probably just like what Lu Chen said.

"The guard disciple said just now that the two of them didn't leave, which means that Han Boyuan should still be here.

"Let's look for it, if the Fire Spirit Bird's seal was not concealed enough, it would have been discovered long ago, and it would be a turn to get it now?" Lu Chen said.

After saying that, go inside.

After passing this crater, it was not too far ahead, and it was already at the end. Lu Chen released his mental power and quickly found a hole in a nearby corner of the wall.

The hole was apparently newly dug.

"They dug a hole here?" Guo Xiuyuan asked in confusion.

Standing at the entrance of the cave, Lu Chen felt that there was no abnormality near the entrance, so he jumped straight down, and fell about ten meters deep. Lu Chen found that there was a tunnel here.

Guo Xiuyuan and Nie Tianli also came down from the hole.

"Why is there a tunnel here?" Guo Xiuyuan's expression changed slightly.

"It seems that your business alliances don't know about this tunnel either," Lu Chen said.

Guo Xiuyuan said: "Our world business alliance has occupied Fengyang Volcano Group for more than a thousand years, and we never knew there were tunnels here."

This tunnel is below the underground palace, no one would have expected that there is a layer below this underground palace.

Walking along the tunnel, not too far, the three came to a wide secret room.

The three were careful, trying to hide their breath as much as possible.

At this time, a burst of laughter suddenly came: "Haha, the ban has finally been resolved. I just sensed that the demon refining pot was in this place, but I didn't expect this to be the place where Du Yang was sitting."

It was Han Boyuan's voice.

Lu Chen, Guo Xiuyuan, and Nie Tianli were all shocked when they heard Han Boyuan's voice. The cracking of the ban was not unexpected. They were surprised that Du Yang died here.

Du Yang was one of the four famous elders of Yuan Shimen, and he was as famous as Chu Jueming, Zhou Daoyan, and Zhang Chongqi, and he actually died in this secret volcano.

As for where Du Yang died, Lu Chen didn't care, he only cared about whether Du Yang would leave Zhou Tian Shenjue behind.

The Zhoutian Divine Art was jointly created by the four elders. Although Chu Jueming had the highest attainments in the Zhoutian Divine Art in the end, each of the four elders could do it.

If Du Yang left some insights on the Zhou Tian Divine Art, it would also be beneficial to Lu Chen's cultivation.

At this time, Yun Yi suddenly said: "We didn't find the Zhoutian Divine Art, only a bunch of magic weapons, not even medicinal pills."

"The pills should have been completely consumed. Take those magic weapons. They are of no use to me. Unfortunately, there are no Nine Heavens Profound Art and Big Dipper Talismans in them," Han Boyuan said.

"Isn't Jiutian Xuangong the town-style martial arts of Tiandaomen? What is the Big Dipper Talisman?" Yun Yi asked.

"Jiutian Xuangong and Beidou Talisman are the keys to unlock the ancient realm. At that time, Du Yang was in charge of the ancient realm of Yuanshimen. Jiutian Xuangong was his proud martial arts. Primordial Spirit Realm is not difficult." Han Boyuan said.

There is a wealth of immortal spiritual power in the ancient realm, which Han Boyuan naturally knows, but what he doesn't know is that Lu Chen and others have already ruined the ancient realm, and even took away the sacred monument. If he knew this, I'm afraid he would be **** off.

Yun Yi could only sigh and said, "Senior Han, let's go. After all, this is the center of the world's business alliance. If someone finds out that something is wrong, it will be troublesome." Fire Spirit Bird, hehe, Fire Spirit Bird is the king of chasing and killing, as long as you find a way to restore Fire Spirit Bird to its former strength, that will be my big help." Han Boyuan laughed.

"What is the peak strength of the Fire Spirit Bird?" Yun Yi asked.

"It's equivalent to the normal ninth level of the Primordial Spirit Realm," Han Boyuan said.

"The ninth level of Yuanshen Realm can be sealed by Du Yang, so Du Yang is so powerful?"

"If you have seen Chu Jueming, you will know that Du Yang is not very powerful, that is, he can only play a tie with me."
