Master, you go first!

Gu Jiu's spirit stone lamp was modified to be similar to the flashlight, and he took out an ordinary spirit stone lamp and handed it to Mu Zhou beside him. A linear lighting and a range lighting worked at the same time.

The lights illuminated the cave, and everyone found that the walls inside the cave were a dark red, as if they had been burned by fire.

As they continued to move forward, they heard the sound of fighting in the cave. Not only the sound of fighting, but also a roar, like the sound of a monster.

Following the direction of the sound, the five people continued to move forward. The cave became bigger and bigger. Finally, they came to a relatively wide place, which seemed to be the center of the cave.

I saw a huge lava pool inside. Due to the existence of this lava pool, the light in the cave became much brighter.

In the middle of the pool, there was a gigantic monster, roaring. The monster looked like a buffalo, with two huge blood-red horns, but the color of its body was similar to the environment here, all red and black.

There were already several monks around fighting against it. The monks were agile, with magic weapons in their hands shining, constantly attacking the monster. The monster, on the other hand, spewed blazing flames from its mouth, fighting with the monks, and from time to time it would use its tail to throw lava to attack the monks.

Gu Jiu and others stood at the entrance here and did not step forward to join the battle.

"Should we go find the place your master mentioned first?" Gu Jiu asked several people for their opinions.

"Let's go." Su Jin nodded.

So a few people walked around the pool where the monks were fighting with the monsters, and saw that there were two entrances in the hall in the center of the cave.

"Which way?" Su Jin asked.

I have no clue. The map Su Yunran gave only marked the entrance to the cave, and did not provide detailed information about the situation inside the cave.

"Whoever has better perception among you can go to the direction where the spiritual energy is thinner." Gu Jiu spoke.

"Why is the spiritual energy so thin? Shouldn't it be rich?" Su Jin didn't understand.

"Because the spiritual energy is gathered together by the Spirit Gathering Array, the remaining spiritual energy is naturally thinner than that in other places. The spiritual energy in other places will continuously flow to the Spirit Gathering Array." Gu Jiu explained in a low voice.

"I see." Su Jin finally understood what Gu Jiu meant.

She let go of her senses and carefully compared the spiritual energy of the two entrances. Then she pointed to the entrance with thinner spiritual energy, and several people entered together.

After entering this entrance, the light became dim again, just like when I entered the cave from the outside.

The spiritual stone lamp had a very good lighting effect and everything around could be seen clearly. The few people continued walking, and the further they went in, the quieter it became. The sound of fighting in the center of the cave gradually disappeared, leaving only the clattering footsteps of a few people.

After walking for a distance, the ground is no longer scorched earth, but stone bricks. The gray-black bricks are laid neatly, and the walls of the cave have also become stone brick walls.

"We should be there soon. This is a place that has been artificially transformed." Gu Jiu said.

There was nothing unusual this time, and they walked smoothly into another wider hall. It was not as big as the center of the cave, but it was also very spacious.

There were several circles of array-like patterns on the ground in the center of the hall, and one could clearly feel the extremely rich spiritual energy in the array patterns.

"That's right, it's here." Gu Jiu stepped forward, stopped at the edge of the outermost array pattern, and stretched out his hand to probe.

Sure enough, it was exactly as Su Yunran described. There was a defensive formation outside. As for its strength, Gu Jiu felt that it was just so-so, not as strong as the one he had set up himself.

"Can it be broken?" Su Jin asked.

"It's not a big problem. Wait a moment, I'll try it." Gu Jiu nodded.

Several people responded and waited for Gu Jiu to break the formation.

Gu Jiu stretched out his hand and pressed on the barrier of the formation, using his spiritual power to touch the formation pattern on the barrier, just like when he broke the formation in Huo Canglin before. However, this formation is a little different. Gu Jiu turned around and said to them,

"This formation is not difficult to break, but the formation patterns are complicated, long and boring, so it will take some time."

"It's okay, just focus on breaking the formation and we'll guard it." Su Jin responded.

Gu Jiu nodded and began to concentrate on breaking the formation. He estimated that it might take nearly half an hour to solve it. What he didn't know was that Su Yunran took a full half day to solve it. Fortunately, Su Yunran was not here, otherwise she would be shocked again.

Time passed little by little, and just when Gu Jiu was halfway through breaking the formation, footsteps were heard in the cave, and it sounded like there were quite a few people. Gu Jiu frowned, could it be that the monster in the central area had been killed? Were these people the group of cultivators just now?

Su Jin and others also stared at the entrance of the hall vigilantly.

After a while, the group of monks at the entrance of the hall came in. There were eight of them, five men and three women. They were the same group that had been fighting with the monster before.

Seeing Gu Jiu standing in the middle of the hall breaking the formation, the leading male cultivator noticed that the concentration of spiritual energy in the formation was extremely high. He realized that it was a spirit gathering formation, and his face became a little greedy.

He said, "Formation Master, that's great. Since we have a spirit gathering formation, fellow Taoists, how about we practice together?"

"You'd better go to the place we found. If too many people go in, the effect of cultivation will be greatly reduced. I think you all know this." Su Jin said to the man.

However, the other party did not seem to be a good person. After listening to what Su Jin said, he did not move at all, and it seemed that he had no intention of leaving. He even looked at Su Jin with a bit of teasing and ill intentions.

He said jokingly, "My beauty, since it will be more effective only if there are fewer people inside, why don't you and I go in together to practice dual cultivation? The effect will definitely be very good. Hahahaha."

Su Jin was immediately annoyed by his provocation, but the other party had more people and their cultivation did not seem to be very poor.

Gu Jiu, who had broken half of the formation, stopped what he was doing and turned to look at the man with disgust in his eyes. He didn't know why, maybe because Su Jin and Shen Nian were too similar, he suddenly felt a nameless anger in his heart, as if the person being teased was Shen Nian, and he couldn't suppress his anger.

Gu Jiu turned around and walked in front of Su Jin, staring at the man and said calmly,

"Would you like to try again?"

"Hey, beauty, is this your Taoist partner? It seems that his cultivation is not very high. Why don't you just follow me? I will take you to get all the resources in the secret realm." The leading male cultivator continued to provoke with a giggle, not even looking at Gu Jiu.

Su Jin blushed a little after hearing what he said. She had followed Su Yunran since she was a child and had been devoted to cultivation without any contact with a Taoist partner. She felt a little embarrassed when she was suddenly misunderstood.

And her embarrassed blushing face caused the leading male cultivator on the opposite side to tease her even more playfully.

“Hahahaha, is your beauty’s face blushing? Then let this pretty boy open the formation so we can start practicing earlier.”
