The underground tunnel is very quiet and deep. In the darkness, you can still hear the footsteps of people in front of you, echoing continuously in this silent underground tunnel.

Listening to the footsteps in the tunnel and the slight sound of wind, Huo Yu felt a little scared. He habitually hugged Muchen's arm and squeezed the weapon on his chest onto Muchen's arm, looking at him with wandering eyes.

Looking ahead, I felt really scared.

Huo Yu said with a trembling voice: "Brother Mu, this tunnel is so deep... I have walked for so long and still haven't reached the end."

Feeling Huo Yu's delicate skin, Muchen enjoyed it but was a little embarrassed at the same time. Seeing Huo Yu's scared expression, Muchen comforted him softly: "Don't worry, don't be afraid. No matter what happens, just remember to stay behind me."

OK, I will protect you."

Huo Yu nodded vigorously. With Muchen's words, Huo Yu's fearful heart gradually calmed down.

It seemed to be very quiet in front of them, and there were no screams, which meant that this staircase was very safe. After walking for a long time, Muchen and others finally saw the end of the stairs, and at the same time, they also heard the sound of fighting coming from the front.

.

"problem occurs!"

Something happened ahead, and the sound of fighting became clearer. Muchen and others immediately quickened their pace, wanting to go down and see what happened.

When Muchen jumped down the stairs, a huge underground palace appeared in front of Muchen's eyes. Unexpectedly, such a huge luxurious palace was hidden under the Flame Mountain.

The palace is splendid, magnificent and majestic. In front of the palace is a golden flaming lion, roaring up to the sky. On both sides of the palace, golden dragons flying into the sky and stone pillars are lifelike, giving people a sense of solemnity. In the square in front of the palace gate, there are two rows of huge towers.

There are 16 stone pillars in total, connected to the zenith, just like 16 strong men holding up the entire ground, creating such a spectacular underground palace. Muchen was also shocked by the palace in front of him.

The entire palace is like a royal palace, hidden underground. The lifelike carvings and splendid decorations look so majestic and majestic, making people feel awe. It is worthy of being a fairy mansion.

Huo Yu: "Wow... what a majestic underground palace! What are those glowing things, gold?" After a brief surprise, everyone was attracted by the sound of fighting in front of them.

I saw that many guards of the Murong family were fighting with the people brought by Ouyang Hua. Both sides seemed to be robbing something on the stone pillars in the square. Muchen took a closer look and saw that there were actually 16 stone pillars on the square in front of the palace.

It is inlaid with many fire-attribute spiritual crystals, and it is these fire-attribute spiritual crystals that gather into the rays of light that illuminate the entire underground palace.

"Fire Spirit Crystals! There are so many." Huo Lian is a fire attribute cultivator and is more sensitive to Fire Spirit Crystals. For Huo Lian, Fire Spirit Crystals are the best auxiliary props for her cultivation, and the 16 stone pillars

On it, there are actually a large number of Fire Spirit Crystals inlaid on it. Each piece is the size of a fist. Any piece is a priceless treasure.

Seeing so many Fire Spirit Crystals, Huo Lian could not contain the impulse in his heart, and immediately rushed towards the stone pillar in front, wanting to join the fight for the Fire Spirit Crystals. However, Muchen held him back.

Huo Lian looked at Muchen doubtfully and said anxiously: "Let me go quickly, that's the Fire Spirit Crystal. I'm going to grab it."

"Why are you so anxious? Didn't you see that the order of the fire spirit crystals is very standardized? The stone pillars are also engraved with spiritual patterns of formations. Before you figure out what the formations are, you should not act rashly..."

Before Muchen could finish speaking, one of the guards of the Murong family had already deducted a piece of Fire Spirit Crystal. It seemed that because one Fire Spirit Crystal was deducted, the other Fire Spirit Crystals on the stone pillar immediately burst out with dazzling light.

, and then a flame laser was ejected from the groove where the Fire Spirit Crystal was held. The Murong family guard was hit from the front and turned into fly ash. Only a piece of Fire Spirit Crystal fell down alone.

The sudden and powerful attack immediately scared everyone away. Unexpectedly, once the fire crystal on the stone pillar was deducted, a flame laser would be ejected from the groove and the person who took the fire crystal would be burned to death. This is

You have to trade your life for the Fire Spirit Crystal.

Seeing the power of the flame laser, everyone immediately moved away from the stone pillar. Only Muchen walked towards the stone pillar and picked up the Fire Spirit Crystal on the ground.

The strange thing is that this time, no flame laser was ejected from the stone pillar. It seemed that the flame laser could only be emitted once.

"The Fire Spirit Crystal after taking it down does not seem to trigger the formation in the stone pillar. It should only be a defensive method for the formation, not a trigger condition. Huolian, here you go." Muchen threw the Fire Spirit Crystal to Huolian.

Start observing the formation spirit patterns on the stone pillars.

These spirit patterns seem to connect all the fire spirit crystals into a whole. Once one of them is missing, the formation will be activated, using the power of the remaining fire spirit crystals to shoot flame lasers. If you want to take away the fire spirit crystals, you must take them at the same time.

Remove all the fire crystals on the stone pillars, otherwise you will be attacked by the stone pillars.

The entire stone pillar was inlaid with hundreds of fire crystals. It was impossible to capture them all at the same time. Muchen didn't want to try the power of the flame laser, so he had to let it go.

As for the remaining people, they could only shake their heads and regret that it was a pity that so many priceless Fire Spirit Crystals could only be looked at but not taken.

At this time, everyone had arrived at the underground palace. After Muchen and others, there were several masters of casual cultivating who also entered the underground palace. Although they were single and weak, their own strength was not weak. At this time, no one could

Not wanting to cause trouble first, I just followed them.

Obviously, the palace in front is the control room of the core formation, and the flame runestones must be inside.

Just the stone pillars in the square outside the palace were inlaid with such fire crystals. If there were no treasures in the palace, no one would be able to do it. The desire for the treasures quickly swallowed up the fear in everyone's hearts, without caring at all that it had just turned into a treasure.

The ashes of the little minions have already begun to form their own teams and slowly move towards the palace.

There were a total of 6 teams that entered the underground palace. The largest one was the Murong family, with twenty-three people, and the lowest strength was at the peak of the Human Martial Realm. There were also more than a dozen masters of the Earth Martial Realm, led by the Wushi brothers.

, is the stronger force on the surface.

Next, there is the Shadow Organization, with a total of 18 people, led by Fan Jin. There are not many strong people in the team. Fan Jin is only at the fifth level of Tianwu Realm, and is considered the weakest force today, but there are more people.

.

The second largest person after the Shadow Organization is the Rukongai force led by Yan Ruyu, which is similar to the Shadow Organization. There are 16 people in the team, including Yan Ruyu's 17 people. Yan Ruyu is the only one who is a master of the Tianwu Realm, and the rest are all from the earth.

Martial arts masters, compared to the Shadow Organization, if the two sides really want to fight, they should be between equals. However, Yan Ruyu and Muchen are allies, and now they are the strongest group.

There are not many people in Ouyang Hua's group. There are only six Earth Martial Realm guards and Ouyang Feng. However, Ouyang Feng is a high-level Tianwu Realm warrior and ranks third in strength here. No one will take advantage of Ouyang Hua's small number of people.

Just despise them.

Similarly, Muchen's side has even fewer people. There are only two sisters, Muchen, Danxin, and Huolianhuoyu. There are only four of them. There is one master of the divine martial realm and one pervert. Yes, in everyone's eyes,

Muchen is a pervert. He is not only an individual cultivator, but also a very violent physical cultivator. His strength is comparable to that of a master of the Divine Martial Realm! And a master of the fourth level of the Tianwu Realm. Fire Feather can only be regarded as a gift. There is no doubt that they are

The strongest force currently.

There are still 5 casual cultivator masters left. All 5 of them are wearing black clothes and covering their faces. They dare not reveal their true faces, and their strength is indeed good. They are all at the lowest level of the Earth Martial Realm. There are two more.

They should be masters of the Tianwu Realm, but their concealment methods are relatively good, and no one can detect their true strength.

These 6 teams all had their own agendas and were wary of everyone around them as they moved slowly towards the palace.

When everyone stepped into the middle of the square, Muchen's heart palpitated. It seemed that something was about to happen. He focused his gaze on the surrounding stone pillars and found that there was a mirror in the middle of each stone pillar. Mirror

There are many spiritual patterns carved around it, which seems to be a formation.

Muchen was somewhat familiar with such a structure. He carefully searched for the memory in his mind and seemed to have thought of something. He suddenly broke into a cold sweat with fear: "Golden Light Array! Damn, it's too much. Quick... Danxin, Huolian, follow me.

"

Because Muchen and others were walking at the end and they were all gathered together. When Muchen shouted, Danxin and Huolian reacted immediately and turned around and ran back. Muchen hugged Huo Yu and ran back too.

The closest place to Muchen and the others was Rukong Street. Although he didn’t know why Muchen ran back, out of trust in Muchen, Yan Ruyu also ordered everyone to run back quickly.

Just as Muchen and others were retreating, the team at the front had already entered the center of the square. After sensing someone intruding, the mirrors among the 16 stone pillars began to light up, and fire-attribute aura began to surge around them.

A powerful flame laser was emitted from the mirror. Many flame lasers were emitted from the mirrors of the 16 stone pillars at the same time, and they were fired randomly in all directions. The hot temperature of the laser directly melted the rocks. If it hit a person, he would be able to escape even if he died.

layer of skin.

After the sudden attack, everyone was briefly shocked and immediately began to organize a resistance. They were already prepared for the danger, and they all took out their own defensive props and began to resist the laser fire.

Because Muchen and the others ran a certain distance forward, they were far away from the dense shooting point in the middle. Although they would be attacked, the attack frequency was not high and it was much easier to deal with them.

Muchen casually scattered the laser with a palm of his hand and said, "No, the power of this golden light array is too weak, and the gathered fire attribute spiritual power is too little."

The golden light array is also a relatively common offensive formation. Precisely because the golden light array is so common, the spiritual patterns derived from it are also diverse, and the methods of array arrangement are also different. Muchen did not immediately

I recognized the golden light array, but there is no doubt about the offensive ability of the golden light array. The power of the golden light array at this time is too weak. The power of a laser can only be compared to the full blow of a master in the middle stage of the Earth Martial Realm. It is much stronger than just now.

The flame laser fired is still weak.

Huo Yu hugged Muchen tightly, and she didn't need to dodge at all. She could still concentrate on answering, "Is it possible that the power of the formation has weakened because it took too long?"

This is possible, because it has been too long, and the pure spiritual power in the Fire Spirit Crystal has long since passed away. It is replaced by ordinary fire-attributed spiritual energy drawn by the formation. Because the spiritual energy is too complex, the power of the formation is naturally reduced.

, coupled with the passage of time and the formation's spiritual patterns being damaged to varying degrees, the golden light array was weakened to this extent.

Such a powerful golden light array does not pose a great threat to Tianwu Realm masters. The Wushi brothers have already walked a long way forward with their shields on their shoulders. Seeing this, Muchen also said quickly: "Quick... let's go along

Walk along the stone pillars, there will be the fewest attacks around the stone pillars."

Although the power of the golden light array is weakened, it is still very dangerous to those Earth Martial Realm warriors. Several Earth Martial Realm masters have had their protective spiritual armor shattered by lasers and were seriously injured. There are also several Human Martial Realm warriors.
