Mode is a talking ground fairy. He usually sleeps underground and leaves a small hole on the ground to breathe. It is precisely because it always drills holes that he discovers the huge space underground in the secret realm. It is worth mentioning that this little guy is now in his 180s.

Fairies are not immortal. According to Mode, ordinary fairies can live to about four hundred years old, while fairies with stronger magic power can live longer.

The next morning, Mode led the way, and Luo Tian tied a rope to this guy's feet, and with the small black siege formation, it could not escape at all.

"Did you see the mountain wall in front? Let's go over."

Walking under the huge mountain wall, looking up, you can see a symbol engraved on the mountain wall. Mod flapped his wings a few times before flying to the front of the symbol. Then his body glowed, and the light shone on the symbol. The entire mountain began to rumbling, and then a huge gap broke through the middle of the mountain wall.

Luo Tian took Xiaobao back a few steps. To his surprise, the entire mountain wall looked like it was made of stone on the outside, but in fact it was a steel skeleton inside. At the same time, a dark and deep passage continued to extend deeper.

"Just below, go." Maud said, pointing to the dark passage.

Luo Tian made a torch, ignited it and walked down the passage. The entire interior was completely steel space, with rusty iron walls on both sides. Maud would automatically shine in the darkness, and the flames could barely see the way forward.

After walking a long distance down, Luo Tian estimated that it was about twenty to thirty meters before the terrain gradually became flat.

"Be careful when moving forward. There are some mechanisms that will be triggered, such as the one on your left." Mode reminded.

Luo Tian took a look and saw a small hole in the iron wall on his left hand, which seemed to be inlaid with a red gem, but there was something that could not be seen clearly in the dark.

He walked forward carefully for a while and arrived at a gate. At the same time, the same symbol appeared next to the gate as when he came in. Mode flew over, and the light on his body reflected on the symbol. The large iron gate in front of him slowly opened as just now.

But when the door opened and Mode flew in, a red light shone down from the air and swept across Luo Tian and Xiaobao's bodies.

"Identify, there are unregistered personnel and are on alert."

A strange female voice suddenly rang underground, and then the originally pitch-black underground space suddenly turned into a red light, and a strange sound came from the distance, as if something was approaching.

"What's going on? What's going on?" Luo Tian retreated nervously and asked Mode.

Mode also looked surprised and said, "I have never encountered such a situation when I came in the past, and I don't know what happened."

The sounds in the distance were getting closer and closer, and three tall figures could be seen in the red light, but when you approached, you would not be a normal person, but like a puppet man crafted from steel.

"Listen, no matter who is talking, I am not a villain, I have no malice, we will leave immediately." Luo Tian shouted to the surroundings.

But the three steel golems had already arrived in front of them, holding weapons that looked like spears. After approaching a certain range, a terrifying arc suddenly appeared on the spear. Then a steel golem directly threw the spear weapons over and stabbed them with a terrifying lightning. Luo Tian saw that the other party launched an attack and immediately retreated and the spiritual shield was unfolded.

The thunder spear hit the spiritual shield and made a "ziz" sound, but it failed to penetrate the spiritual shield.

"So that's it, I was shocked." The spiritual shield was not penetrated, which means that the opponent's strength was very weak. Luo Tian was relieved and put on the mask of Yin Jiu to forge and rushed over.

The crazy sword was useless. The three steel puppets were not strong enough. At most, they were at the seventh or eighth level of the Qi Refining Realm. They were beaten into pieces by Luo Tian’s palms.

"The guard was killed and verified that the invader was a monk. The alarm was temporarily lifted, and the alert level increased in three hours." The emotional female voice came again, and the red light around temporarily disappeared and turned back into darkness.

Luo Tian held up a torch and illuminated the broken steel puppets on the ground. These steel puppets have different skills from those in the martial arts world. Luo Tian had never even seen similar puppets. It seems that they are driven by electricity, while the puppets on the mainland are driven by magic arrays and spiritual energy.

"Xiaobao, do you know what this is?" Luo Tian asked.

Xiaobao shook his head and thought about it and said, "I have seen it in some books from the old era. It seems that in the old era, it was called a robot, which was a kind of puppet man driven by electricity. However, the skills in it are different from the skills of our puppet man on the mainland today, so many sects and families who tried to copy these robots failed."

How could things from the old era appear underground in the secret realm of the demon clan? Luo Tian felt strange since the beginning that the environment here seemed to be out of place with the outside world.

"Let's go quickly." Mod said.

Luo Tian hesitated, and it should be even more dangerous to move forward. It was not convenient for him to take Xiaobao. After thinking about it, he said, "Xiaobao, you and Xiaohei leave here first and wait in the cave where we camped yesterday. I am sure that this place is safe and will come to pick you up. If I haven't come out for a long time, you can return to our entrance and wait there for the entrance door to open. You can take all the dry food. If it is not enough, Xiaohei will help you hunt."

Xiaobao was a little scared, hesitated for a moment, nodded, and followed Xiao Hei to the outside.

"Let's keep moving forward."

I avoided many mechanisms along the way, but I never saw the steel golem who I had seen before seemed to be much safer.

"Further forward, passing through the door is what I call the underground spiritual spring." Mod pointed to the front and said.

Just as it was about to pass, the red light that had disappeared for a while turned on again, and the voice of the woman who had no feelings also sounded again.

"The alert level is increased, and the elite guards are activated."

The sound of footsteps came from the corridors on both sides of the left and right at the same time. Some taller steel golemists were surrounding Luo Tian. The weapons in their hands were different, and they turned into some huge iron blocks, but one end of these iron blocks had a hole.

“Clear unregistered outsiders.”

The moment the female voice disappeared, a large number of beams of light were shot out from the iron blocks that had opened their holes. These beams were powerful and had high temperatures. Even the steel plates were melted wherever they swept.

Soon the beam shot into Luo Tian's spiritual energy shield, which was much stronger than the three steel puppets I had encountered before, and reached the level close to the human puppet realm, but he still couldn't break Luo Tian's spiritual energy shield. Luo Tian's in the evil state roared and released a terrifying evil light. The evil light swept across the corridor to both sides, and in an instant, he cut off all the steel puppets in half.

"The alert level has been upgraded again. A cultivator in the Human Pill Realm was detected. The killer was activated in three hours."

The female voice sounded again, and then the red light disappeared. The same words as before made Luo Tian's heart slightly sank. It seemed that after a while, a stronger monster would come to deal with him.

Passing through the front door, a glowing sculpture stood in front of Luo Tian in the darkness, and a trace of spiritual energy turned into white smoke and surged outward from the surroundings of the sculpture. This is the legendary spiritual energy spring.

"This is the first time I have seen the spiritual spring..."

Luo Tian seemed to feel that the air had become sweeter, and the surroundings were very quiet. The spiritual energy was invisible, but when a large amount of spiritual energy was piled up together, it would form a white smoke state.

The power of monks comes from spiritual energy, and the spiritual spring eye is like an endless treasure for monks.

Luo Tian walked over slowly. After approaching the spiritual spring, he felt that every meridian and every inch of his skin were extremely comfortable.

"The spring is under this sculpture. The sculpture is just an ornament. Okay, I have done what I promised you. You should let me go." Mod said.

Luo Tian's face darkened and said, "Didn't you tell me there is no danger?"

Mode smiled awkwardly and said, "I don't know either. I have never encountered an attack when I came in the past. I don't think it's my problem, but your problem. Maybe this place doesn't welcome humans but only demon clans. After all, this is the secret realm of our demon clan."
